Progress towards achieving national goals for improved quality of life among cis-gender Black women with HIV
Raiford JL , Tie Y , Yuan XA , Byrd KK , Buchacz KA , Beer L . Aids 2024 38 (7) 1087-1090 Data from the CDC's Medical Monitoring Project indicate that the United States is on track to meet one of five National HIV/AIDS Strategy (NHAS) Quality of Life goals among cisgender Black women, specifically, hunger/food insecurity. Substantial work needs to be done to improve self-rated health and to decrease unmet need for mental health services. Enhanced and coordinated action are necessary to reach all Quality of Life goals in this NHAS priority population. |
Unmet needs for HIV ancillary services among persons with diagnosed HIV aged 55 years and older
Byrd KK , Buchacz K , Crim SM , Beer L , Lu JF , Dasgupta S . J Acquir Immune Defic Syndr 2023 BACKGROUND: Approximately two in five persons with HIV (PWH) in the United States are aged ≥55 years. HIV ancillary services, such as case management and transportation services, can help older PWH remain engaged in care. We used data from the Medical Monitoring Project (MMP) to describe the prevalence of unmet needs for ancillary services among persons with diagnosed HIV aged ≥55 years. SETTING: Medical Monitoring Project is an annual cross-sectional study that reports representative estimates on adults with diagnosed HIV in the United States. METHODS: We used MMP data collected during 6/2019-5/2021 to calculate weighted percentages of cisgender men and cisgender women with HIV aged ≥55 years with unmet needs for ancillary services, overall and by selected characteristics (N=3,200). Unmet need was defined as needing but not receiving a given ancillary service. We assessed differences between groups using prevalence ratios (PRs) and 95% confidence intervals (CIs) with predicted marginal means. RESULTS: Overall, 37.7% of cisgender men and women with HIV aged ≥55 years had ≥1 unmet need for ancillary services. Overall, 16.6% had ≥1 unmet need for HIV support services, 26.9% for non-HIV medical services, and 26.7% for subsistence services. There were no statistically significant differences in unmet needs for services by gender. The prevalence of ≥1 unmet need was higher among non-White persons (PR range: 1.35-1.63), persons who experienced housing instability (PR=1.70), and those without any private insurance (PR range: 1.49-1.83). CONCLUSION: A large percentage of older PWH have unmet needs for ancillary services. Given the challenges that older PWH face related to the interaction of HIV and aging-associated factors, deficits in the provision of ancillary services should be addressed. |

Centers for Disease Control and Prevention , Sawyer MH , Hoerger TJ , Murphy TV , Schillie SF , Hu D , Spradling PR , Byrd KK , Xing J , Reilly ML , Tohme RA , Moorman A , Smith EA , Baack BN , Jiles RB , Klevens M , Ward JW , Kahn HS , Zhou F . MMWR Morb Mortal Wkly Rep 2011 60 (50) 1709-11 Hepatitis B virus (HBV) causes acute and chronic infection of the liver leading to substantial morbidity and mortality. In the United States, since 1996, a total of 29 outbreaks of HBV infection in one or multiple long-term-care (LTC) facilities, including nursing homes and assisted-living facilities, were reported to CDC; of these, 25 involved adults with diabetes receiving assisted blood glucose monitoring. These outbreaks prompted the Hepatitis Vaccines Work Group of the Advisory Committee on Immunization Practices (ACIP) to evaluate the risk for HBV infection among all adults with diagnosed diabetes. The Work Group reviewed HBV infection-related morbidity and mortality and the effectiveness of implementing infection prevention and control measures. The strength of scientific evidence regarding protection was evaluated using the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) methodology,* and safety, values, and cost-effectiveness were incorporated into a recommendation using the GRADE system. Based on the Work Group findings, on October 25, 2011, ACIP recommended that all previously unvaccinated adults aged 19 through 59 years with diabetes mellitus (type 1 and type 2) be vaccinated against hepatitis B as soon as possible after a diagnosis of diabetes is made (recommendation category A). Data on the risk for hepatitis B among adults aged ≥60 years are less robust. Therefore, ACIP recommended that unvaccinated adults aged ≥60 years with diabetes may be vaccinated at the discretion of the treating clinician after assessing their risk and the likelihood of an adequate immune response to vaccination (recommendation category B). This report summarizes these recommendations and provides the rationale used by ACIP to inform their decision making. |

Nucleic Acids Res 2023 52 D1333-D1346 ![]() ![]() The Human Phenotype Ontology (HPO) is a widely used resource that comprehensively organizes and defines the phenotypic features of human disease, enabling computational inference and supporting genomic and phenotypic analyses through semantic similarity and machine learning algorithms. The HPO has widespread applications in clinical diagnostics and translational research, including genomic diagnostics, gene-disease discovery, and cohort analytics. In recent years, groups around the world have developed translations of the HPO from English to other languages, and the HPO browser has been internationalized, allowing users to view HPO term labels and in many cases synonyms and definitions in ten languages in addition to English. Since our last report, a total of 2239 new HPO terms and 49235 new HPO annotations were developed, many in collaboration with external groups in the fields of psychiatry, arthrogryposis, immunology and cardiology. The Medical Action Ontology (MAxO) is a new effort to model treatments and other measures taken for clinical management. Finally, the HPO consortium is contributing to efforts to integrate the HPO and the GA4GH Phenopacket Schema into electronic health records (EHRs) with the goal of more standardized and computable integration of rare disease data in EHRs. |
Update on outbreak of fungal meningitis among U.S. residents who received epidural anesthesia at two clinics in Matamoros, Mexico
Smith DJ , Gold JAW , Chiller T , Bustamante ND , Marinissen MJ , Rodriquez GG , Cortes VBG , Molina CD , Williams S , Vazquez Deida AA , Byrd K , Pappas PG , Patterson TF , Wiederhold NP , Thompson Iii GR , Ostrosky-Zeichner L . Clin Infect Dis 2023 ![]() ![]() BACKGROUND: Public health officials are responding to an outbreak of fungal meningitis among patients who received procedures under epidural anesthesia at two clinics (River Side Surgical Center and Clinica K-3) in Matamoros, Mexico, during January 1-May 13, 2023. This report describes outbreak epidemiology and outlines interim diagnostic and treatment recommendations. METHODS: Interim recommendations for diagnosis and management were developed by the Mycoses Study Group Research Education and Consortium (MSGERC) based on the clinical experience of clinicians caring for patients during the current outbreak or during previous outbreaks of healthcare-associated fungal meningitis in Durango, Mexico, and the United States. RESULTS: As of July 7, 2023, the situation has evolved into a multistate and multinational fungal meningitis outbreak. A total of 185 residents in 22 U.S. states and jurisdictions have been identified who might be at risk of fungal meningitis because they received epidural anesthesia at the clinics of interest in 2023. Among these patients, 11 suspected, 10 probable, and 10 confirmed U.S. cases have been diagnosed, with severe vascular complications and eight deaths occurring. Fusarium solani species complex has been identified as the causative agent, with antifungal susceptibility testing of a single isolate demonstrating poor in vitro activity for most available antifungals. Currently, triple therapy with intravenous voriconazole, liposomal amphotericin B, and fosmanogepix is recommended. CONCLUSIONS: Efforts to understand the source of this outbreak and optimal treatment approaches are ongoing, but infectious diseases physicians should be aware of available treatment recommendations. New information will be available on CDC's website. |
Possible exposures among mpox patients without reported male-to-male sexual contact - six U.S. Jurisdictions, November 1-December 14, 2022
Sharpe JD , Charniga K , Byrd KM , Stefanos R , Lewis L , Watson J , Feldpausch A , Pavlick J , Hand J , Sokol T , Ortega E , Pathela P , Hennessy RR , Dulcey M , McHugh L , Pietrowski M , Perella D , Shah S , Maroufi A , Taylor M , Cope A , Belay ED , Ellington S , McCollum AM , Zilversmit Pao L , Guagliardo SAJ , Dawson P . MMWR Morb Mortal Wkly Rep 2023 72 (35) 944-948 The extent to which the 2022 mpox outbreak has affected persons without a recent history of male-to-male sexual contact (MMSC) is not well understood. During November 1-December 14, 2022, CDC partnered with six jurisdictional health departments to characterize possible exposures among mpox patients aged ≥18 years who did not report MMSC during the 3 weeks preceding symptom onset. Among 52 patients included in the analysis, 14 (27%) had a known exposure to a person with mpox, including sexual activity and other close intimate contact (eight) and household contact (six). Among 38 (73%) patients with no known exposure to a person with mpox, self-reported activities before illness onset included sexual activity and other close intimate contact (17; 45%), close face-to-face contact (14; 37%), attending large social gatherings (11; 29%), and being in occupational settings involving close skin-to-skin contact (10; 26%). These findings suggest that sexual activity remains an important route of mpox exposure among patients who do not report MMSC. |
Cost-outcome analysis of HIV testing and counseling, linkage, and defaulter tracing services in Bukoba, Tanzania
Suraratdecha C , MacKellar D , Steiner C , Rwabiyago OE , Cham HJ , Msumi O , Maruyama H , Kundi G , Byrd J , Weber R , Mkemwa G , Kazaura K , Justman J , Rwebembera A . AIDS Care 2023 1-8 Effective services along the HIV continuum of care from HIV testing and counseling to linkage, and from linkage to antiretroviral therapy (ART) initiation and retention, are key to improved health outcomes of persons living with HIV. A comprehensive analysis of the costs and outcomes of cascade services is needed to help allocate and prioritize resources to achieve UNAIDS targets. We evaluated the costs and population-level impact of a community-wide, integrated scale-up of testing, linkage, and defaulter-tracing programs implemented in Bukoba Municipal Council, Tanzania. Costs per identified HIV-positive client for provider-initiated, and home- and venue-based testing and counseling were $92.64 United States dollars (USD), $256.33 USD, and $281.57 USD, respectively. Costs per patient linked to HIV care and ART were $47.69 USD and $74.12 USD, respectively, during all ART-eligibility periods combined. Costs per defaulter traced and returned to HIV care were $47.56 USD and $206.77 USD, respectively. The provider-initiated testing and counseling was the most cost-effective modality. Testing approaches targeted to populations groups and geographic location with high testing positivity rates may improve the overall efficiency of testing services. The expansion of ART eligibility criteria and high linkage rate also result in efficiency gains and economies of scale of linkage services. |
Survey of invasive mosquito surveillance and control capacity in Southeastern USA reveals training and resource needs

J Am Mosq Control Assoc 2023 39 (2) 108-121 Several invasive mosquito species that are nuisances or of medical and veterinary importance have been introduced into the Southeastern region of the USA, posing a threat to other species and the local ecosystems and/or increasing the risk of pathogen transmission to people, livestock, and domestic pets. Prompt and effective monitoring and control of invasive species is essential to prevent them from spreading and causing harmful effects. However, the capacity for invasive mosquito species surveillance is highly variable among mosquito control programs in the Southeast, depending on a combination of factors such as regional geography and climate, access to resources, and the ability to interact with other programs. To facilitate the development of invasive mosquito surveillance in the region, we, the Mosquito BEACONS (Biodiversity Enhancement and Control of Non-native Species) working group, conducted a survey on the capacities of various public health agencies and pest control agencies engaged in mosquito surveillance and control in seven Southeastern states (Alabama, Florida, Georgia, Louisiana, Mississippi, North Carolina, and South Carolina). Ninety control programs completed the survey, representing an overall response rate of 25.8%. We report key findings from our survey, emphasizing the training and resource needs, and discuss their implications for future invasive mosquito surveillance and control capacity building. By increasing communication and collaboration opportunities (e.g., real-time sharing of collection records, coordinated multistate programs), the establishment of Mosquito BEACONS and the implementation of this survey can accelerate knowledge transfer and improve decision support capacity in response to or in preparation for invasive mosquito surveillance and can establish infrastructure that can be used to inform programs around the world. |

MMWR Morb Mortal Wkly Rep 2023 72 (15) 404-410 As of March 7, 2023, a total of 30,235 confirmed and probable monkeypox (mpox) cases were reported in the United States,(†) predominantly among cisgender men(§) who reported recent sexual contact with another man (1). Although most mpox cases during the current outbreak have been self-limited, cases of severe illness and death have been reported (2-4). During May 10, 2022-March 7, 2023, 38 deaths among persons with probable or confirmed mpox(¶) (1.3 per 1,000 mpox cases) were reported to CDC and classified as mpox-associated (i.e., mpox was listed as a contributing or causal factor). Among the 38 mpox-associated deaths, 94.7% occurred in cisgender men (median age = 34 years); 86.8% occurred in non-Hispanic Black or African American (Black) persons. The median interval from symptom onset to death was 68 days (IQR = 50-86 days). Among 33 decedents with available information, 93.9% were immunocompromised because of HIV. Public health actions to prevent mpox deaths include integrated testing, diagnosis, and early treatment for mpox and HIV, and ensuring equitable access to both mpox and HIV prevention and treatment, such as antiretroviral therapy (ART) (5). |
Evaluation of community-based, mobile HIV-care, peer-delivered linkage case management in Manzini Region, Eswatini
Suraratdecha C , MacKellar D , Hlophe T , Dlamini M , Ujamaa D , Pals S , Dube L , Williams D , Byrd J , Mndzebele P , Behel S , Pathmanathan I , Mazibuko S , Tilahun E , Ryan C . Int J Environ Res Public Health 2022 20 (1) The success of antiretroviral therapy (ART) requires continuous engagement in care and optimal levels of adherence to achieve sustained HIV viral suppression. We evaluated HIV-care cascade costs and outcomes of a community-based, mobile HIV-care, peer-delivered linkage case-management program (CommLink) implemented in Manzini region, Eswatini. Abstraction teams visited referral facilities during July 2019-April 2020 to locate, match, and abstract the clinical data of CommLink clients diagnosed between March 2016 and March 2018. An ingredients-based costing approach was used to assess economic costs associated with CommLink. The estimated total CommLink costs were $2 million. Personnel costs were the dominant component, followed by travel, commodities and supplies, and training. Costs per client tested positive were $499. Costs per client initiated on ART within 7, 30, and 90 days of diagnosis were $2114, $1634, and $1480, respectively. Costs per client initiated and retained on ART 6, 12, and 18 months after diagnosis were $2343, $2378, and $2462, respectively. CommLink outcomes and costs can help inform community-based HIV testing, linkage, and retention programs in other settings to strengthen effectiveness and improve efficiency. |
Operational insights into mosquito control disaster response in Coastal North Carolina: Experiences with the Federal Emergency Management Agency after Hurricane Florence
Brown Jeffrey S , Byrd Brian D , Connelly CRoxanne , Richards Stephanie L . J Environ Health 2022 85 (2) 24-31 Preparation for post-hurricane mosquito control is essential for an effective emergency response to protect public health and promote recovery efforts. Effective pre-hurricane planning includes laying the groundwork for a successful reimbursement application to the Federal Emergency Management Agency. The critical and overlapping need to sustain funding for mosquito control programs is highlighted here in the context of both normal and emergency responses. Community support is an integral component of an effective integrated pest management program and is established over time with appropriate communication and engagement. Experienced mosquito control operators who are familiar with treatment areas are an essential component of successful operations. Here, practical advice is provided to plan, prepare, and implement a successful ground- and aerial-based mosquito control response. |
HIV Testing Before and During the COVID-19 Pandemic - United States, 2019-2020.
DiNenno EA , Delaney KP , Pitasi MA , MacGowan R , Miles G , Dailey A , Courtenay-Quirk C , Byrd K , Thomas D , Brooks JT , Daskalakis D , Collins N . MMWR Morb Mortal Wkly Rep 2022 71 (25) 820-824 HIV testing is a core strategy for the Ending the HIV Epidemic in the U.S. (EHE) initiative, which has the aim of reducing new HIV infections by at least 90% by 2030.* During 2016-2017, jurisdictions with the highest HIV diagnosis rates were those with higher prevalences of HIV testing; past-year HIV testing was higher among persons who reported recent HIV risk behaviors compared with those who did not report these risks (1). During 2020-2021, the COVID-19 pandemic disrupted health care delivery, including HIV testing in part because many persons avoided services to comply with COVID-19 risk mitigation efforts (2). In addition, public health departments redirected some sexual health services to COVID-19-related activities.(†) CDC analyzed data from four national data collection systems to assess the numbers of HIV tests performed and HIV infections diagnosed in the United States in the years before (2019) and during (2020) the COVID-19 pandemic. In 2020, HIV diagnoses reported to CDC decreased by 17% compared with those reported in 2019. This decrease was preceded by decreases in HIV testing during the same period, particularly among priority populations including Black or African American (Black) gay men, Hispanic or Latino (Hispanic) gay men, bisexual men, other men who have sex with men (MSM), and transgender persons in CDC-funded jurisdictions. To compensate for testing and diagnoses missed during the COVID-19 pandemic and to accelerate the EHE initiative, CDC encourages partnerships among federal organizations, state and local health departments, community-based organizations, and health care systems to increase access to HIV testing services, including strategies such as self-testing and routine opt-out screening in health care settings. |
Antiretroviral therapy initiation and retention among clients who received peer-delivered linkage case management and standard linkage services, Eswatini, 2016-2020: retrospective comparative cohort study
MacKellar D , Hlophe T , Ujamaa D , Pals S , Dlamini M , Dube L , Suraratdecha C , Williams D , Byrd J , Tobias J , Mndzebele P , Behel S , Pathmanathan I , Mazibuko S , Tilahun E , Ryan C . Arch Public Health 2022 80 (1) 74 BACKGROUND: Persons living with HIV infection (PLHIV) who are diagnosed in community settings in sub-Saharan Africa are particularly vulnerable to barriers to care that prevent or delay many from obtaining antiretroviral therapy (ART). METHODS: We conducted a retrospective cohort study to assess if a package of peer-delivered linkage case management and treatment navigation services (CommLink) was more effective than peer-delivered counseling, referral, and telephone follow-up (standard linkage services, SLS) in initiating and retaining PLHIV on ART after diagnosis in community settings in Eswatini. HIV-test records of 773 CommLink and 769 SLS clients aged15years diagnosed between March 2016 and March 2018, matched by urban and rural settings of diagnosis, were selected for the study. CommLink counselors recorded resolved and unresolved barriers to care (e.g., perceived wellbeing, fear of partner response, stigmatization) during a median of 52days (interquartile range: 35-69) of case management. RESULTS: Twice as many CommLink than SLS clients initiated ART by 90days of diagnosis overall (88.4% vs. 37.9%, adjusted relative risk (aRR): 2.33, 95% confidence interval (CI): 1.97, 2.77) and during test and treat when all PLHIV were eligible for ART (96.2% vs. 37.1%, aRR: 2.59, 95% CI: 2.20, 3.04). By 18months of diagnosis, 54% more CommLink than SLS clients were initiated and retained on ART (76.3% vs. 49.5%, aRR: 1.54, 95% CI: 1.33, 1.79). Peer counselors helped resolve 896 (65%) of 1372 identified barriers of CommLink clients. Compared with clients with3 unresolved barriers to care, 42% (aRR: 1.42, 95% CI: 1.19, 1.68) more clients with 1-2 unresolved barriers, 44% (aRR: 1.44, 95% CI: 1.25, 1.66) more clients with all barriers resolved, and 54% (aRR: 1.54, 95% CI: 1.30, 1.81) more clients who had no identified barriers were initiated and retained on ART by 18months of diagnosis. CONCLUSIONS: To improve early ART initiation and retention among PLHIV diagnosed in community settings, HIV prevention programs should consider providing a package of peer-delivered linkage case management and treatment navigation services. Clients with multiple unresolved barriers to care measured as part of that package should be triaged for differentiated linkage and retention services. |

Infect Control Hosp Epidemiol 2022 43 (11) 1-9 ![]() OBJECTIVE: The incidence of infections from extended-spectrum β-lactamase (ESBL)-producing Enterobacterales (ESBL-E) is increasing in the United States. We describe the epidemiology of ESBL-E at 5 Emerging Infections Program (EIP) sites. METHODS: During October-December 2017, we piloted active laboratory- and population-based (New York, New Mexico, Tennessee) or sentinel (Colorado, Georgia) ESBL-E surveillance. An incident case was the first isolation from normally sterile body sites or urine of Escherichia coli or Klebsiella pneumoniae/oxytoca resistant to ≥1 extended-spectrum cephalosporin and nonresistant to all carbapenems tested at a clinical laboratory from a surveillance area resident in a 30-day period. Demographic and clinical data were obtained from medical records. The Centers for Disease Control and Prevention (CDC) performed reference antimicrobial susceptibility testing and whole-genome sequencing on a convenience sample of case isolates. RESULTS: We identified 884 incident cases. The estimated annual incidence in sites conducting population-based surveillance was 199.7 per 100,000 population. Overall, 800 isolates (96%) were from urine, and 790 (89%) were E. coli. Also, 393 cases (47%) were community-associated. Among 136 isolates (15%) tested at the CDC, 122 (90%) met the surveillance definition phenotype; 114 (93%) of 122 were shown to be ESBL producers by clavulanate testing. In total, 111 (97%) of confirmed ESBL producers harbored a blaCTX-M gene. Among ESBL-producing E. coli isolates, 52 (54%) were ST131; 44% of these cases were community associated. CONCLUSIONS: The burden of ESBL-E was high across surveillance sites, with nearly half of cases acquired in the community. EIP has implemented ongoing ESBL-E surveillance to inform prevention efforts, particularly in the community and to watch for the emergence of new ESBL-E strains. |
HIV testing and ART initiation among partners, family members, and high-risk associates of index clients participating in the CommLink linkage case management program, Eswatini, 2016-2018
Williams D , MacKellar D , Dlamini M , Byrd J , Dube L , Mndzebele P , Mazibuko S , Ao T , Pathmanathan I , Beyer A , Ryan C . PLoS One 2021 16 (12) e0261605 To help diagnose and initiate antiretroviral therapy (ART) for ≥95% of all persons living with HIV (PLHIV), the World Health Organization (WHO) recommends offering HIV testing to biological children, and sexual and needle-sharing partners of all PLHIV (index-client testing, ICT). Many index clients, however, do not identify or have contactable partners, and often substantially fewer than 95% of HIV-positive partners initiate ART soon after index testing. To help improve early HIV diagnosis and ART initiation in Eswatini (formerly Swaziland), we implemented a community-based HIV testing and peer-delivered, linkage case management program (CommLink) that provided ICT as part of a comprehensive package of WHO recommended linkage services. CommLink was implemented June 2015 -March 2017 (Phase I), and April 2017 -September 2018 (Phase II). In addition to biological children and partners, HIV testing was offered to adult family members (Phases I and II) and high-risk associates including friends and acquaintances (Phase II) of CommLink index clients. Compared with Phase I, in Phase II proportionally more CommLink clients disclosed their HIV-infection status to a partner or family member [94% (562/598) vs. 75% (486/652)], and had ≥1 partners, family members, or high-risk associates (contacts) tested through CommLink [41% (245/598) vs. 18% (117/652)]. Of 537 contacts tested, 253 (47%) were HIV-positive and not currently in HIV care, including 17% (17/100) of family members aged <15 years, 42% (78/187) of non-partner family members aged ≥15 years, 60% (73/121) of sexual partners, and 66% (85/129) of high-risk associates. Among 210 HIV-positive contacts aged ≥15 years who participated in CommLink, nearly all received recommended linkage services including treatment navigation (95%), weekly telephone follow-up (93%), and ≥3 counseling sessions (94%); peer counselors resolved 76% (306/404) of identified barriers to care (e.g., perceived wellness); and 200 (95%) initiated ART at a healthcare facility, of whom 196 (98%) received at least one antiretroviral refill before case-management services ended. To help countries achieve ≥90% ART coverage among all PLHIV, expanding ICT for adult family members and high-risk associates of index clients, and providing peer-delivered linkage case management for all identified PLHIV, should be considered. |
Retention in Medical Care Among Insured Adolescents and Young Adults With Diagnosed HIV Infection, United States, 2010-2014
Tanner MR , Bush T , Nesheim SR , Weidle PJ , Byrd KK . Public Health Rep 2021 137 (4) 333549211023266 OBJECTIVES: Retention in care is a critical component of effective HIV treatment, and adolescents and young adults are at higher risk of inadequate retention than older adults. The objective of our study was to examine the patterns of retention in care among adolescents and young adults with HIV infection by analyzing Medicaid and commercial health insurance claims data. METHODS: We evaluated retention in care for HIV-diagnosed adolescents and young adults aged 13-24 using the 2010-2014 MarketScan Medicaid and MarketScan Commercial Claims health insurance databases. The study period extended 36 months from the date of the first claim with a code for HIV or AIDS. We determined the unweighted proportion retained in care for the Medicaid and Commercial Claims cohorts for months 0-24 and 25-36. We assessed associations between demographic characteristics and retention in care using logistic regression. RESULTS: A total of 378 adolescents and young adults were in the Medicaid cohort and 1028 in the Commercial Claims cohort. In the Medicaid and Commercial Claims cohorts, respectively, 186 (49%) and 591 (57%) adolescents and young adults were retained in care during months 0-24. In the Medicaid cohort, 113 (73%) people retained in care and 69 (45%) people not retained in care during months 0-24 were retained in care during months 25-36. In the Commercial Claims cohort, 313 (77%) and 94 (31%) retained and not retained people, respectively, were found to be in care during months 25-36. CONCLUSIONS: Notable proportions of HIV-diagnosed adolescents and young adults are not adequately retained in care; public health interventions tailored to this population are needed. |
Factors associated with concussion symptom knowledge and attitudes towards concussion care-seeking in a national survey of parents of middle school children in the U.S
Kerr ZY , Nedimyer AK , Kay MC , Chandran A , Gildner P , Byrd KH , Haarbauer-Krupa JK , Register-Mihalik JK . J Sport Health Sci 2020 10 (2) 113-121 OBJECTIVE: Developing appropriate concussion prevention and management paradigms in middle school (MS) settings requires understanding parents' general levels of concussion-related knowledge and attitudes. This study examined factors associated with concussion symptom knowledge and care-seeking attitudes among parents of MS children (aged ∼10-15 years). METHODS: A panel of 1224 randomly selected US residents, aged ≥18 years and identifying as parents of MS children, completed an online questionnaire capturing parental and child characteristics. The parents' concussion symptom knowledge was measured using 25 questions, with possible answers being "yes", "maybe", and "no". Correct answers earned 2 points, "maybe" answers earned 1 point, and incorrect answers earned 0 points (range = 0-50; higher scores = better knowledge). Concussion care-seeking attitudes were also collected using five 7-point scale items (range = 5-35; higher scores = more positive attitudes). Multivariable ordinal logistic regression models identified predictors of higher scores. Models met proportional odds assumptions. Adjusted odds ratios (aOR) with 95% confidence intervals (CI) (excluding 1.00) were deemed statistically significant. RESULTS: Median scores were 39 (interquartile range (IQR) = 32-44) for symptom knowledge and 32 (IQR = 28-35) for care-seeking attitude. In multivariable models, odds of better symptom knowledge were higher in women vs. men (aOR = 2.28; 95%CI: 1.71-3.05), white/non-Hispanics vs. other racial or ethnic groups (aOR = 1.88; 95%CI: 1.42-2.49), higher parental age (10-year-increase aOR = 1.47; 95%CI: 1.26-1.71) and greater competitiveness (10%-scale-increase aOR = 1.24; 95%CI: 1.13-1.36). Odds of more positive care-seeking attitudes were higher in white/non-Hispanics versus other racial or ethnic groups (aOR = 1.45; 95%CI: 1.06-1.99), and higher parental age (10-year-increase aOR = 1.24; 95%CI: 1.05-1.47). CONCLUSION: Characteristics of middle school children's parents (e.g., sex, race or ethnicity, age) are associated with their concussion symptom knowledge and care-seeking attitudes. Parents' variations in concussion knowledge and attitudes warrant tailored concussion education and prevention. |
Community-wide HIV testing, linkage case management, and defaulter tracing in Bukoba, Tanzania: pre-intervention and post-intervention, population-based survey evaluation

Lancet HIV 2020 7 (10) e699-e710 BACKGROUND: Community randomised trials have had mixed success in implementing combination prevention strategies that diagnose 90% of people living with HIV, initiate and retain on antiretroviral therapy (ART) 90% of those diagnosed, and achieve viral load suppression in 90% of those on ART (90-90-90). The Bukoba Combination Prevention Evaluation (BCPE) aimed to achieve 90-90-90 in Bukoba Municipal Council, Tanzania, by scaling up new HIV testing, linkage, and retention interventions. METHOD: We did population-based, cross-sectional surveys before and after our community-wide intervention in Bukoba-a mixed urban and rural council of approximately 150 000 residents located on the western shore of Lake Victoria in Tanzania. BCPE interventions were implemented in 11 government-supported health-care facilities throughout Bukoba from Oct 1, 2014, to March 31, 2017, when national ART-eligibility guidelines expanded from CD4 counts of less than 350 cells per μL (Oct 1, 2014-Dec 31, 2015) and 500 or less cells per μL (Jan 1, 2016-Sept 30, 2016) to any CD4 cell count (test and treat, Oct 1, 2016-March 31, 2017). We used pre-intervention (Nov 4, 2013-Jan 25, 2014) and post-intervention (June 21, 2017-Sept 20, 2017) population-based household surveys to assess population prevalence of undiagnosed HIV infection and ART coverage, and progress towards 90-90-90, among residents aged 18-49 years. FINDINGS: During the 2·5-year intervention, BCPE did 133 695 HIV tests, diagnosed and linked 3918 people living with HIV to HIV care at 11 Bukoba facilities, and returned to HIV care 604 patients who had stopped care. 4795 and 5067 residents aged 18-49 years participated in pre-intervention and post-intervention surveys. HIV prevalence before and after the intervention was similar: pre-intervention 8·9% (95% CI 7·5-10·4); post-intervention 8·4% (6·9-9·9). Prevalence of undiagnosed HIV infection decreased from 4·7% to 2·0% (prevalence ratio 0·42, 95% CI 0·31-0·57), and current ART use among all people living with HIV increased from 32·2% to 70·9% (2·20, 1·82-2·66) overall, 23·0% to 62·1% among men (2·70, 1·84-3·96), and 16·7% to 64·4% among people aged 18-29 years (3·87, 2·54-5·89). Of 436 and 435 people living with HIV aged 18-49 years who participated in pre-intervention and post-intervention surveys, previous HIV diagnosis increased from 47·4% (41·3-53·4) to 76·2% (71·8-80·6), ART use among diagnosed people living with HIV increased from 68·0% (60·9-75·2) to 93·1% (90·2-96·0), and viral load suppression of those on ART increased from 88·7% (83·6-93·8) to 91·3% (88·6-94·1). INTERPRETATION: BCPE findings suggest scaling up recommended HIV testing, linkage, and retention interventions can help reduce prevalence of undiagnosed HIV infection, increase ART use among all people living with HIV, and make substantial progress towards achieving 90-90-90 in a relatively short period. BCPE facility-based testing and linkage interventions are undergoing national scale up to help achieve 90-90-90 in Tanzania. FUNDING: US Presidents' Emergency Plan for AIDS Relief. |
Overcoming barriers to HIV care: Findings from a peer-delivered, community-based, linkage case management program (CommLink), Eswatini, 2015-2018
MacKellar D , Williams D , Dlamini M , Byrd J , Dube L , Mndzebele P , Mazibuko S , Pathmanathan I , Tilahun E , Ryan C . AIDS Behav 2020 25 (5) 1518-1531 To help persons living with HIV (PLHIV) in Eswatini initiate antiretroviral therapy (ART), the CommLink case-management program provided a comprehensive package of linkage services delivered by HIV-positive, peer counselors. Of 1250 PLHIV participants aged ≥ 15 years diagnosed in community settings, 75% reported one or more barriers to care (e.g., fearing stigmatization). Peer counselors helped resolve 1405 (65%) of 2166 identified barriers. During Test and Treat (October 2016-September 2018), the percentage of participants who initiated ART and returned for ≥ 1 antiretroviral refills was 92% overall (759/824); 99% (155/156) among participants without any identified barriers; 96% (544/564) among participants whose counselors helped resolve all or all but one barrier; and 58% (59/102) among participants who had ≥ 2 unresolved barriers to care. The success of CommLink is attributed, at least in part, to peer counselors who helped their clients avoid or at least temporarily resolve many well-known barriers to HIV care. |
Roles for pharmacists in the "Ending the HIV Epidemic: A Plan for America" initiative
McCree DH , Byrd KK , Johnston M , Gaines M , Weidle PJ . Public Health Rep 2020 135 (5) 547-554 In 2019, President Trump announced a new initiative, Ending the HIV Epidemic: A Plan for America (EHE). EHE will use 3 key strategies-diagnose, treat, and prevent-to reduce new HIV infections at least 90% by 2030, as well as new laboratory methods and epidemiological techniques to respond quickly to potential outbreaks. Partnerships are an important component in the initiative's success. Pharmacists and pharmacies can play important roles in EHE, including dispensing antiretroviral therapy and providing HIV screening, adherence counseling, medication therapy management, preexposure prophylaxis, and nonprescription syringe sales. The objective of this report is to discuss potential roles that pharmacists and pharmacies can play under the key strategies of EHE. |
Costs and cost-effectiveness of the patient-centered HIV Care Model: A collaboration between community-based pharmacists and primary medical providers
Shrestha RK , Schommer JC , Taitel MS , Garza OW , Camp NM , Akinbosoye OE , Clay PG , Byrd KK . J Acquir Immune Defic Syndr 2020 85 (3) e48-e54 BACKGROUND: The Patient-centered HIV Care Model (PCHCM) is an evidence-informed structural intervention that integrates community-based pharmacists with primary medical providers to improve rates of HIV viral suppression. This report assesses the costs and cost-effectiveness of the PCHCM. SETTING: Patient-centered HIV Care Model METHODS:: Three project sites, each composed of a medical clinic and one or two community-based HIV-specialized pharmacies, were included in the analyses. PCHCM required patient data sharing between medical providers and pharmacists and collaborative therapy-related decision making. Intervention effectiveness was measured as the incremental number of patients virally suppressed (HIV RNA <200 copies/mL at the last test in a 12-month measurement period). Micro-costing direct measurement methods were used to estimate intervention. The cost per patient, cost per patient visit, and incremental cost per patient virally suppressed were calculated from the health care providers' perspective. Additionally, the number of HIV transmissions averted, lifetime HIV treatment cost saved, quality-adjusted life years (QALYs) saved, and cost per QALY saved were calculated from the societal perspective, using standard methods and reported values from the published literature. RESULTS: Overall, the PCHCM annual intervention cost for the three project sites was $226,741. The average cost per patient, cost per patient visit, and incremental cost per patient virally suppressed were $813, $48, and $5,039, respectively. The intervention averted 2.75 HIV transmissions and saved 12.22 QALYs and nearly $1.28 million in lifetime HIV treatment costs. The intervention was cost saving overall and at each project site. CONCLUSIONS: The PCHCM can be delivered at a relatively low cost and is a cost-saving intervention to assist patients in achieving viral suppression and preventing HIV transmission. |
Improvements in retention in care and HIV viral suppression among persons with HIV and comorbid mental health conditions: Patient-centered HIV care model
Byrd KK , Hardnett F , Hou JG , Clay PG , Suzuki S , Camp NM , Shankle MD , Weidle PJ , Taitel MS . AIDS Behav 2020 24 (12) 3522-3532 The Patient-centered HIV Care Model (PCHCM) integrated community-based pharmacists with medical providers and required sharing of patient clinical information and collaborative therapy-related action planning. We determined the proportions of participants with HIV and mental health conditions who were retained in care and the proportion virally suppressed, pre- and post-implementation. Overall, we found a relative 13% improvement in both retention [60% to 68% (p = 0.009)] and viral suppression [79% to 90% (p < 0.001)]. Notable improvements were seen among persons triply diagnosed with HIV, mental illness and substance use [+ 36% (50% to 68%, p = 0.036) and + 32% (66% to 86%, p = 0.001) in retention and viral suppression, respectively]. There were no differences in the proportions of persons adherent to psychiatric medications, pre- to post-implementation, nor were there differences in the proportions of persons retained in care or virally suppressed by psychiatric medication adherence, post-implementation. PCHCM demonstrated that collaborations between community-based pharmacists and medical providers can improve HIV care continuum outcomes among persons with mental health conditions. |

Kerr ZY , Chandran A , Nedimyer AK , Rothschild AE , Kay MC , Gildner P , Byrd KH , Haarbauer-Krupa JK , Register-Mihalik JK . J Sport Health Sci 2020 11 (6) 716-724 OBJECTIVE: Parents may use various information sources to obtain information about sport-related concussions (SRC). This study examined SRC-related information sources used by parents of United States middle school (MS) children (aged approximately 10-15 years). METHODS: A panel of 1083 randomly selected U.S. residents, aged >/=18 years and identifying as parents of MS children, completed an online questionnaire capturing parental and child characteristics, and utilization and perceived trustworthiness of various sources of SRC-related information. Multivariable logistic regression models identified factors associated with utilizing each source. Adjusted odds ratios (OR) with 95% confidence intervals (CIs) excluding 1.00 were deemed significant. RESULTS: Doctors/healthcare providers (49.9%) and other healthcare-related resources (e.g., Centers for Disease Control and Prevention, WebMD) (37.8%) were common SRC-related information sources; 64.0% of parents utilized at least one of these sources. Both sources were considered "very" or "extremely" trustworthy for SRC-related information among parents using these sources (doctors/healthcare providers: 89.8%; other healthcare-related resources: 70.9%). A 10-year increase in parental age was associated with higher odds of utilizing doctors/healthcare providers (adjusted odd ratio (ORadjusted)=1.09, 95%CI: 1.02-1.16) and other healthcare-related resources (ORadjusted=1.11, 95%CI: 1.03-1.19). The odds of utilizing doctors/healthcare providers (ORadjusted=0.58, 95%CI: 0.40-0.84) and other healthcare-related resources (ORadjusted=0.64, 95%CI: 0.44-0.93) were lower among parents whose MS children had concussion histories versus the parents of children who did not have concussion histories. CONCLUSIONS: One-third of parents did not report using doctors/healthcare providers or other healthcare-related resources for SRC-related information. Factors associated with under-utilization of these sources may be targets for future intervention. Continuing education for healthcare providers and educational opportunities for parents should highlight accurate and up-to-date SRC-related information. |
Association between malaria infection and early childhood development mediated by anemia in rural Kenya
Milner EM , Kariger P , Pickering AJ , Stewart CP , Byrd K , Lin A , Rao G , Achando B , Dentz HN , Null C , Fernald LCH . Int J Environ Res Public Health 2020 17 (3) Malaria is a leading cause of morbidity and mortality among children under five years of age, with most cases occurring in Sub-Saharan Africa. Children in this age group in Africa are at greatest risk worldwide for developmental deficits. There are research gaps in quantifying the risks of mild malaria cases, understanding the pathways linking malaria infection and poor child development, and evaluating the impact of malaria on the development of children under five years. We analyzed the association between malaria infection and gross motor, communication, and personal social development in 592 children age 24 months in rural, western Kenya as part of the WASH Benefits environmental enteric dysfunction sub-study. Eighteen percent of children had malaria, 20% were at risk for gross motor delay, 21% were at risk for communication delay, and 23% were at risk for personal social delay. Having a positive malaria test was associated with increased risk for gross motor, communication, and personal social delay while adjusting for child characteristics, household demographics, study cluster, and intervention treatment arm. Mediation analyses suggested that anemia was a significant mediator in the pathway between malaria infection and risk for gross motor, communication, and personal social development delays. The proportion of the total effect of malaria on the risk of developmental delay that is mediated by anemia across the subscales was small (ranging from 9% of the effect on gross motor development to 16% of the effect on communication development mediated by anemia). Overall, malaria may be associated with short-term developmental delays during a vulnerable period of early life. Therefore, preventative malaria measures and immediate treatment are imperative for children's optimal development, particularly in light of projections of continued high malaria transmission in Kenya and Africa. |
Characteristics and current clinical practices of opioid treatment programs in the United States
Jones CM , Byrd DJ , Clarke TJ , Campbell TB , Ohuoha C , McCance-Katz EF . Drug Alcohol Depend 2019 205 107616 BACKGROUND: Given rising rates of opioid use disorder (OUD) and related consequences, opioid treatment programs (OTPs) can play a pivotal role in the U.S. opioid crisis. There is a paucity of recent research to guide how best to leverage OTPs in the opioid response. METHODS: We conducted a national survey of U.S. OTPs using a 46-question electronic survey instrument covering three domains: 1) OTP characteristics; 2) services offered; and 3) current clinical practices. Descriptive statistics and multivariable logistic regression examined variables in these domains. RESULTS: Among responding OTPs, 32.4% reported using all three medications for OUD treatment; 95.8% used methadone, 61.8% used buprenorphine, and 43.9% used naltrexone. The mean (SD) number of patients currently receiving methadone was 383 (20.4), buprenorphine 51 (7.0), extended-release naltrexone 6 (1.0). Viral hepatitis testing was provided by 60.9% of OTPs, 15.3% provided hepatitis B vaccination, 14.9% provided hepatitis A vaccination, and 12.6% provided medication treatment for hepatitis C virus infection. HIV testing was provided by 60.7% of OTPs, 9.5% provided pre-exposure prophylaxis, and 8.4% provided medication treatment for HIV. OTP characteristics associated with using all three forms of medications for OUD included: providing medication for alcohol use disorder (aOR=5.24, 95% CI:2.99-9.16), providing telemedicine services (aOR=3.82, 95% CI:2.14-6.84), and directly providing naloxone to patients (aOR=2.57, 95% CI:1.53-4.29). Multiple barriers to providing buprenorphine and extended-release naltrexone were identified. CONCLUSIONS: Efforts are needed to increase availability of all medications approved to treat OUD in OTPs, integrate infectious disease-related services, and expand the reach of OTPs in the U.S. |
Pharmacy data as an alternative data source for implementation of a data to care strategy
Byrd KK , Camp NM , Iqbal K , Weidle PJ . J Acquir Immune Defic Syndr 2019 82 Suppl 1 S53-s56 ![]() BACKGROUND: Data to Care (D2C) is a strategy for using health departments' HIV surveillance data (HIV viral load and CD4 laboratory reports) to identify and re-engage not-in-care persons with HIV. In the current D2C model, there is a delay in the identification of persons not in care due to the time interval between recommended monitoring tests (ie, every 3-6 months) and the subsequent reporting of these tests to the health department. METHODS: Pharmacy claims and fulfillment data can be used to identify persons with HIV who have stopped filling antiretroviral therapy and are at risk of falling out of care. Because most antiretrovirals (ARVs) are prescribed as a 30-day supply of medication, these data can be used to identify persons who are not filling their medications on a monthly basis. The use of pharmacy claims data to identify persons not filling ARV prescriptions is an example of how "big data" can be used to conduct a modified D2C model. RESULTS: Although a D2C strategy using pharmacy data has not been broadly implemented, a few health departments are implementing demonstration projects using this strategy. As the projects progress, processes and outcomes can be evaluated. CONCLUSIONS: Tracking ARV refill data can be a more real-time indicator of poor adherence and can help identify HIV-infected persons at risk of falling out of HIV medical care. |
Threefold increases in population HIV viral load suppression among men and young adults - Bukoba Municipal Council, Tanzania, 2014-2017
MacKellar D , Steiner C , Rwabiyago OE , Cham HJ , Pals S , Maruyama H , Msumi O , Kundi G , Byrd J , Weber R , Madevu-Matson C , Kazaura K , Rutachunzibwa T , Mmari E , Morales F , Justman J , Cain K , Rwebembera A . MMWR Morb Mortal Wkly Rep 2019 68 (30) 658-663 Reducing HIV-related morbidity and mortality, and effectively eliminating HIV transmission risk, depends on use of antiretroviral therapy (ART) to achieve and maintain viral load suppression (VLS)* (1,2). By 2020, sub-Saharan African countries are working to achieve VLS among 90% of persons using ART and 73% of all persons living with HIV infection (1). In Tanzania, a country with 1.4 million persons with HIV infection, 49.6% of HIV-positive persons aged 15-49 years had achieved VLS in 2017, including only 21.5% of men and 44.6% of women aged 25-29 years (3). To identify interventions that might increase VLS in Tanzania, and reduce VLS-associated sex and age-group disparities, the Bukoba Combination Prevention Evaluation (BCPE) scaled up new HIV testing, linkage to care, and retention on ART interventions throughout Bukoba Municipal Council (Bukoba), Tanzania, during October 2014-March 2017 (4,5). Located on the western shore of Lake Victoria, Bukoba is a mixed urban and rural municipality of 150,000 persons and capital of Kagera Region. Of the 31 regions of Tanzania, Kagera has the fourth highest prevalence of HIV infection (6.8%) among residents aged 15-49 years (3). CDC analyzed data from BCPE preintervention and postintervention surveys and found that VLS prevalence among HIV-positive Bukoba residents aged 18-49 years increased approximately twofold overall (from 28.6% to 64.8%) and among women (33.3% to 67.8%) and approximately threefold among men (20.5% to 59.1%) and young adults aged 18-29 years (15.6% to 56.7%). During 2017, BCPE facility-based testing and linkage interventions were approved as new service delivery models by the Tanzania Ministry of Health, Community Development, Gender, Elderly and Children (4,5). After a successful rollout to 208 facilities in 11 regions in 2018, BCPE interventions are being scaled up in all regions of Tanzania in 2019 with support from the United States President's Emergency Plan for AIDS Relief (PEPFAR). |
Antiretroviral adherence level necessary for HIV viral suppression using real-world data
Byrd KK , Hou JG , Hazen R , Kirkham H , Suzuki S , Clay PG , Bush T , Camp NM , Weidle PJ , Delpino A . J Acquir Immune Defic Syndr 2019 82 (3) 245-251 BACKGROUND: A benchmark of near-perfect adherence (>/=95%) to antiretroviral therapy (ART) is often cited as necessary for HIV viral suppression. However, given newer, more effective ART medications the threshold for viral suppression might be lower. We estimated the minimum ART adherence level necessary to achieve viral suppression. SETTINGS: The Patient-centered HIV Care Model demonstration project. METHODS: Adherence to ART was calculated using the Proportion of Days Covered (PDC) measure for the 365-day period prior to each viral load test result, and grouped into five categories (<50%, 50%-<80%, 80%-<85%, 85%-<90%, and >/=90%). Binomial regression analyses were conducted to determine factors associated with viral suppression (HIV RNA <200 copies/mL); demographics, PDC category and ART regimen type were explanatory variables. Generalized estimating equations with an exchangeable working correlation matrix accounted for correlation within subjects. In addition, probit regression models were used to estimate adherence levels required to achieve viral suppression in 90% of HIV viral load tests. RESULTS: The adjusted odds of viral suppression did not differ between persons with an adherence level of 80%-<85% or 85%-<90% and those with an adherence level of >/=90%. Additionally, the overall estimated adherence level necessary to achieve viral suppression in 90% of viral load tests was 82% and varied by regimen type; integrase inhibitor- and non-nucleoside reverse transcriptase inhibitor-based regimens achieved 90% viral suppression with adherence levels of 75% and 78%, respectively. CONCLUSIONS: The ART adherence level necessary to reach HIV viral suppression may be lower than previously thought and may be regimen dependent. |
Methods, outcomes, and costs of a 2.5 year comprehensive facility-and community-based HIV testing intervention in Bukoba Municipal Council, Tanzania, 2014-2017
Cham HJ , MacKellar D , Maruyama H , Rwabiyago OE , Msumi O , Steiner C , Kundi G , Weber R , Byrd J , Suraratdecha C , Mengistu T , Churi E , Pals S , Madevu-Matson C , Alexander G , Porter S , Kazaura K , Mbilinyi D , Morales F , Rutachunzibwa T , Justman J , Rwebembera A . PLoS One 2019 14 (5) e0215654 To diagnose >/=90% HIV-infected residents (diagnostic coverage), the Bukoba Combination Prevention Evaluation (BCPE) implemented provider-initiated (PITC), home- (HBHTC), and venue-based (VBHTC) HIV testing and counseling (HTC) intervention in Bukoba Municipal Council, a mixed urban and rural lake zone community of 150,000 residents in Tanzania. This paper describes the methods, outcomes, and incremental costs of these HTC interventions. PITC was implemented in outpatient department clinics in all eight public and three faith-based health facilities. In clinics, lay counselors routinely screened and referred eligible patients for HIV testing conducted by HTC-dedicated healthcare workers. In all 14 wards, community teams offered HTC to eligible persons encountered at 31,293 home visits and at 79 male- and youth-frequented venues. HTC was recommended for persons who were not in HIV care or had not tested in the prior 90 days. BCPE conducted 133,695 HIV tests during the 2.5 year intervention (PITC: 88,813, 66%; HBHTC: 27,407, 21%; VBHTC: 17,475, 13%). Compared with other strategies, PITC conducted proportionally more tests among females (65%), and VBHTC conducted proportionally more tests among males (69%) and young-adults aged 15-24 years (42%). Of 5,550 (4.2% of all tests) HIV-positive tests, 4,143 (75%) clients were newly HIV diagnosed, including 1,583 males and 881 young adults aged 15-24 years. Of HIV tests conducted 3.7%, 1.8%, and 2.1% of PITC, HBHTC, and VBHTC clients, respectively, were newly HIV diagnosed; PITC accounted for 79% of all new diagnoses. Cost per test (per new diagnosis) was $4.55 ($123.66), $6.45 ($354.44), and $7.98 ($372.67) for PITC, HBHTC, and VBHTC, respectively. In a task-shifting analysis in which lay counselors replaced healthcare workers, estimated costs per test (per new diagnosis) would have been $3.06 ($83.15), $ 4.81 ($264.04), and $5.45 ($254.52), for PITC, HBHTC, and VBHTC, respectively. BCPE models reached different target groups, including men and young adults, two groups with consistently low coverage. Implementation of multiple models is likely necessary to achieve >/=90% diagnostic coverage. |
Adherence and viral suppression among participants of the Patient-centered HIV Care Model project-a collaboration between community-based pharmacists and HIV clinical providers
Byrd KK , Hou JG , Bush T , Hazen R , Kirkham H , Delpino A , Weidle PJ , Shankle MD , Camp NM , Suzuki S , Clay PG . Clin Infect Dis 2019 70 (5) 789-797 BACKGROUND: HIV viral suppression (VS) decreases morbidity, mortality, and transmission risk. METHODS: The Patient-centered HIV Care Model (PCHCM) integrated community-based pharmacists with HIV medical providers and required them to share patient clinical information, identify therapy-related problems, and develop therapy-related action plans.Proportions of persons adherent to antiretroviral therapy (Proportion of Days Covered [PDC] >/=90%) and virally suppressed (HIV RNA <200 copies/mL), pre- and post-PCHCM implementation, were compared. Factors associated with post-implementation VS were determined using multivariable logistic regression. Participant demographics, baseline viral load (VL), and PDC were explanatory variables in the models. PDC was modified to account for time to last VL in the year post-implementation, and stratified as: >/=90%, <90-80%, <80-50%, <50%. RESULTS: The 765 enrolled participants were 43% non-Hispanic black, 73% male, with a median age of 48 years (interquartile range: 38-55); 421 and 649 were included in the adherence and VS analyses, respectively. Overall, proportions adherent to therapy remained unchanged. However, VS improved a relative 15% (75% to 86%, p<0.001). Persons with higher modified PDC (adjusted odds ratio [AOR] 1.74 per one-level increase in PDC category; 95% CI: 1.30-2.34) and those virally suppressed at baseline (AOR 7.69; CI: 3.96-15.7) had greater odds of post-implementation suppression. Although non-Hispanic black persons (AOR 0.29; CI: 0.12-0.62) had lower odds of suppression, VS improved a relative 23% (63% to 78%, p<0.001), pre- to post-implementation. CONCLUSION: Integrated care models between community-based pharmacists and primary medical providers may identify and address HIV therapy-related problems and improve overall VS among persons with HIV. |
