Health service utilization patterns among Medicaid enrollees with intellectual and developmental disabilities before and during the COVID-19 pandemic: Implications for pandemic response and recovery efforts
Kearly A , Hluchan M , Brazeel C , Lane JT , Oputa J , Baio J , Cree RA , Cheng Q , Wray A , Payne C , Gerling J , Pham T , Ekart S . J Public Health Manag Pract 2024 OBJECTIVES: To assess the impact of COVID-19 on health service utilization of adults with intellectual and developmental disabilities (IDDs) through an analysis of Medicaid claims data. DESIGN: Retrospective cohort study of Medicaid claims. SETTING AND PARTICIPANTS: Medicaid members aged 25 to 64 years from January 1, 2018, to March 31, 2021, from the states of Louisiana, Pennsylvania, and Wyoming. INTERVENTION: We analyzed data from two 12-month time periods (pre-COVID-19 and during COVID-19) and assessed the potential impact of the COVID-19 pandemic on health service utilization and service intensity for 3 cohorts: (1) IDD with preexisting mental health diagnoses, (2) IDD without mental health diagnoses, and (3) all other Medicaid members. MAIN OUTCOME MEASURE: Health service utilization determined by specific claims data classifications. RESULTS: The analysis showed reduced utilization for nonmental health service types with differing utilization patterns for IDD with preexisting mental health diagnoses, IDD without mental health diagnoses, and all other Medicaid members. Change in utilization varied, however, for mental health service types. Measures of service intensity showed decreased numbers of members utilizing services across most service types and increased Medicaid claims per person across most mental health service categories but decreased Medicaid claims per person for most nonmental health services. CONCLUSIONS: Results suggest a need for mental health services among all Medicaid members during the COVID-19 pandemic. By anticipating these needs, communities may be able to expand outreach to Medicaid members through enhanced case management, medication checks, and telemedicine options. |
Best practices and lessons learned from the public health disability specialists program: Addressing the needs of people with disabilities during COVID-19
Cree RA , Wray A , Evans A , Lyons S , Burrous H , Nilz M , Clarke C , Li J , Baio J . J Public Health Manag Pract 2024 CONTEXT: The Association of State and Territorial Health Officials (ASTHO) and the National Association of County and City Health Officials (NACCHO) applied funding issued by the US Centers for Disease Control and Prevention (CDC) to implement the Public Health Disability Specialists Program, part of a project to address the needs of people with disabilities during the COVID-19 pandemic. Disability specialists (subject matter experts) were embedded within state, territorial, and city/county health departments to help ensure disability inclusion in emergency planning, mitigation, and recovery efforts. OBJECTIVE: To evaluate the success of the Disability Specialists Program in improving emergency response planning, mitigation, and recovery efforts for people with disabilities within participating jurisdictions. DESIGN: Disability specialists worked with their assigned jurisdictions to conduct standardized baseline health department needs assessments to identify existing gaps and inform development and implementation of improvement plans. CDC, ASTHO, and NACCHO implemented a mixed methods framework to evaluate specialists' success. SETTING: State, territorial, and local health departments across 28 jurisdictions between January 2021 and July 2022. MAIN OUTCOME MEASURES: Average number of categories of gaps addressed and qualitative documentation of strategies, barriers, and promising practices. RESULTS: Specialists identified 1010 gaps (approximately 36 per jurisdiction) across eight needs assessment categories, most related to mitigation, recovery, resilience, and sustainability efforts (n = 213) and communication (n = 193). Specialists addressed an average of three categories of gaps identified; common focus areas included equitable COVID-19 vaccine distribution and accessible communications. Specialists commonly mentioned barriers related to limited health agency capacity (eg, resources) and community mistrust. Promising practices to address barriers included sharing best practices through peer-to-peer networks and building and strengthening partnerships between health departments and the disability community. CONCLUSIONS: Embedding disability specialists within state, territorial, and local health departments improved jurisdictional ability to meet evolving public health needs for the entire community, including people with disabilities. |
Prevalence and correlates of suspected and diagnosed traumatic brain injuries among US school-aged children
Haarbauer-Krupa J , Wray AP , Lebrun-Harris LA , Cree RA , Womack LS . J Pediatr Clin Pract 2024 14 Objective: To (1) estimate the lifetime prevalence of suspected and diagnosed traumatic brain injury (TBI) based on parent report overall and select sociodemographic characteristics; and (2) describe differences in prevalence of health conditions and health-related risk factors by whether a child had a lifetime history of diagnosed TBI. Study design: We analyzed data from the 2020 National Survey of Children's Health, a cross-sectional address-based survey of US households. A categorical variable was created on the basis of parent responses to 3 questions inquiring about their suspicion of their child having a brain injury, if they sought medical care, and if the health care provider provided a diagnosis. Parents also were asked to report on their child's additional health conditions, functional indicators, school and social factors, and health care access and service use. Results: The prevalence of lifetime diagnosed TBI was 4.2% (95% CI 3.8-4.5). Children with a parent-reported lifetime history of diagnosed TBI were more likely to have a variety of health conditions, special health care needs, disabilities, activity limitations, missed days of school, and unmet care coordination needs, compared with those without a history. However, they were more likely to have a usual source of sick care and to receive more health-related services. Conclusions: For school-aged children, a history of TBI is associated with parent-reported health needs and conditions, as well as missed days from school. It is particularly important for parents to seek care when they suspect their child has experienced a TBI to receive a diagnosis and monitor the impacts of the TBI. © 2024 |

Lancet HIV 2024 BACKGROUND: In 2014, UNAIDS set a goal to end the AIDS epidemic by achieving targets for the percentage of people living with HIV who were aware of their status, on antiretroviral therapy (ART), and virally suppressed. In 2020, these targets were revised to 95% for each measure (known as 95-95-95), to be reached among people living with HIV by 2025. We used data from the Fifth Botswana AIDS Impact Survey (BAIS V) to measure progress towards these testing and treatment targets in Botswana. METHODS: BAIS V used a two-stage cluster design to obtain a nationally representative sample of people aged 15-64 years in Botswana. During March-August, 2021, 14 763 consenting participants were interviewed and tested for HIV in their households by survey teams. HIV-positive specimens were tested for viral load, presence of antiretroviral drugs, and recency of infection using the HIV-1 limiting antigen avidity enzyme immunoassay. Estimates of HIV-positive status and use of ART were based on self-report and the analysis of blood specimens for antiretroviral drugs. Viral load suppression was defined as an HIV RNA concentration of less than 1000 copies per mL. HIV incidence was calculated using the recent infection testing algorithm. Data were weighted to account for the complex survey design. FINDINGS: The national HIV prevalence in Botswana among people aged 15-64 years was 20·8% and the annual incidence of HIV infection was 0·2%. 95·1% (men 93·0%, women 96·4%) of people living with HIV aged 15-64 years were aware of their status, 98·0% (men 97·2%, women 98·4%) of those aware were on ART, and 97·9% (men 96·6%, women 98·6%) of those on ART had viral load suppression. Among young people (aged 15-24 years) living with HIV, 84·5% were aware of their status, 98·5% of those aware were on ART, and 91·6% of those on ART had viral load suppression. The prevalance of viral load suppression among all people living with HIV was 91·8%, and varied by district-ranging from 85·3% in Gaborone to 100·0% in Selibe Phikwe. INTERPRETATION: BAIS V is the first population-based survey worldwide to report the achievement of the UNAIDS 95-95-95 goals, both overall and among women. Strategies to reach undiagnosed men and young people, including young women, are needed. FUNDING: US President's Emergency Plan for AIDS Relief. |
Point of care CD4 testing in national household surveys - results and quality indicators from eleven population-based HIV impact assessment (PHIA) surveys
Birhanu S , Winterhalter FS , Stupp P , Cates M , Rottinghaus E , Yavo D , Wray-Gordon F , Lupoli K , Ndongmo CB , Longwe H , Reid GA , Metz M , Saito S , McCracken S , Brown K , Voetsch AC , Duong YT , Parekh BS , Patel HK . Microbiol Spectr 2023 11 (3) e0314822 Population-based HIV Impact Assessments (PHIAs) are national household (HH) surveys that provide HIV diagnosis and CD4 testing with an immediate return of results. Accurate CD4 results improve HIV-positive participants' clinical care and inform the effectiveness of HIV programs. Here, we present CD4 results from the PHIA surveys that were conducted in 11 countries in sub-Saharan Africa between 2015 and 2018. All of the HIV-positive participants and 2 to 5% of the HIV-negative participants were offered Pima CD4 (Abbott, IL, USA) point-of-care (POC) tests. The quality of the CD4 test was ensured by conducting instrument verification, comprehensive training, quality control, a review of testing errors and an analysis of unweighted CD4 data by HIV status, age, gender, and antiretroviral (ARV) treatment status. Overall, CD4 testing was completed for 23,085 (99.5%) of the 23,209 HIV-positive and 7,329 (2.7%) of the 270,741 negative participants in 11 surveys. The instrument error rate was 11.3% (range, 4.4% to 15.7%). The median CD4 values among HIV-positive and HIV-negative participants (aged 15+) were 468 cells/mm(3) (interquartile range [IQR], 307 to 654) and 811 cells/mm(3) (IQR, 647 to 1,013), respectively (P < 0.0001). Among the HIV-positive participants (aged 15+), those with detectable ARVs had higher CD4 values (508 cells/mm(3)) than those with undetectable ARVs (385.5 cells/mm(3)). Among the HIV-positive participants (aged 15+), 11.4% (2,528/22,253) had a CD4 value of less than 200 cells/mm(3), and approximately half of them (1,225/2,528 = 48.5%) had detectable ARVs, whereas 51.5% (1,303/2,528) had no detectable ARVs. We successfully implemented high quality POC CD4 testing using Pima instruments. Our data come from nationally representative surveys in 11 countries and provide unique insights regarding the CD4 distribution among HIV-positive individuals as well as the baseline CD4 values among HIV-negative individuals. IMPORTANCE The manuscript describes CD4 levels among HIV-positive individuals and baseline CD4 levels among HIV-negative individuals from 11 sub-Saharan countries, thereby highlighting the importance of CD4 markers in the context of the HIV epidemic. Despite increased ARV access in each country, advanced HIV disease (CD4 < 200 cells/mm(3)) persists among approximately 11% of HIV-positive individuals. Therefore, it is important that our findings are shared with the scientific community to assist with similar implementations of point-of-care testing and to conduct a review of HIV programmatic gaps. |

Patel HK , Duong YT , Birhanu S , Dobbs T , Lupoli K , Moore C , Detorio M , Sleeman K , Manjengwa J , Wray-Gordon F , Yavo D , Jackson K , Domaoal RA , Yufenyuy EL , Vedapuri S , Ndongmo CB , Ogollah FM , Dzinamarira T , Rubinstein P , Sachathep KK , Metz M , Longwe H , Saito S , Brown K , Voetsch AC , Parekh BS . J Acquir Immune Defic Syndr 2021 87 S17-s27 BACKGROUND: Conducting HIV surveys in resource-limited settings is challenging because of logistics, limited availability of trained personnel, and complexity of testing. We described the procedures and systems deemed critical to ensure high-quality laboratory data in the population-based HIV impact assessments and large-scale household surveys. METHODS: Laboratory professionals were engaged in every stage of the surveys, including protocol development, site assessments, procurement, training, quality assurance, monitoring, analysis, and reporting writing. A tiered network of household, satellite laboratories, and central laboratories, accompanied with trainings, optimized process for blood specimen collection, storage, transport, and real-time monitoring of specimen quality, and test results at each level proved critical in maintaining specimen integrity and high-quality testing. A plausibility review of aggregate merged data was conducted to confirm associations between key variables as a final quality check for quality of laboratory results. RESULTS: Overall, we conducted a hands-on training for 3355 survey staff across 13 surveys, with 160-387 personnel trained per survey on biomarker processes. Extensive training and monitoring demonstrated that overall, 99% of specimens had adequate volume and 99.8% had no hemolysis, indicating high quality. We implemented quality control and proficiency testing for testing, resolved discrepancies, verified >300 Pima CD4 instruments, and monitored user errors. Aggregate data review for plausibility further confirmed the high quality of testing. CONCLUSIONS: Ongoing engagement of laboratory personnel to oversee processes at all levels of the surveys is critical for successful national surveys. High-quality population-based HIV impact assessments laboratory data ensured reliable results and demonstrated the impact of HIV programs in 13 countries. |

Williams AM , Ladva CN , Leon JS , Lopman BA , Tangpricha V , Whitehead RD , Armitage AE , Wray K , Morovat A , Pasricha SR , Thurnham D , Tanumihardjo SA , Shahab-Ferdows S , Allen L , Flores-Ayala RC , Suchdev PS . Am J Clin Nutr 2019 110 (6) 1456-1464 BACKGROUND: To accurately assess micronutrient status, it is necessary to characterize the effects of inflammation and the acute-phase response on nutrient biomarkers. OBJECTIVE: Within a norovirus human challenge study, we aimed to model the inflammatory response of C-reactive protein (CRP) and alpha-1-acid glycoprotein (AGP) by infection status, model kinetics of micronutrient biomarkers by inflammation status, and evaluate associations between inflammation and micronutrient biomarkers from 0 to 35 d post-norovirus exposure. METHODS: Fifty-two healthy adults were enrolled into challenge studies in a hospital setting and followed longitudinally; all were exposed to norovirus, half were infected. Post hoc analysis of inflammatory and nutritional biomarkers was performed. Subjects were stratified by inflammation resulting from norovirus exposure. Smoothed regression models analyzed the kinetics of CRP and AGP by infection status, and nutritional biomarkers by inflammation. Linear mixed-effects models were used to analyze the independent relations between CRP, AGP, and biomarkers for iron, vitamin A, vitamin D, vitamin B-12, and folate from 0 to 35 d post-norovirus exposure. RESULTS: Norovirus-infected subjects had median (IQR) peak concentrations for CRP [16.0 (7.9-29.5) mg/L] and AGP [0.9 (0.8-1.2) g/L] on day 3 and day 4 postexposure, respectively. Nutritional biomarkers that differed (P < 0.05) from baseline within the inflamed group were ferritin (elevated day 3), hepcidin (elevated days 2, 3), serum iron (depressed days 2-4), transferrin saturation (depressed days 2-4), and retinol (depressed days 3, 4, and 7). Nutritional biomarker concentrations did not differ over time within the uninflamed group. In mixed models, CRP was associated with ferritin (positive) and serum iron and retinol (negative, P < 0.05). CONCLUSION: Using an experimental infectious challenge model in healthy adults, norovirus infection elicited a time-limited inflammatory response associated with altered serum concentrations of certain iron and vitamin A biomarkers, confirming the need to consider adjustments of these biomarkers to account for inflammation when assessing nutritional status. These trials were registered at clinicaltrials.gov as NCT00313404 and NCT00674336. |
Assessment of U.S. pediatrician knowledge of toxocariasis
Woodhall DM , Garcia AP , Shapiro CA , Wray SL , Shane AL , Mani CS , Stimpert KK , Fox LM , Montgomery SP . Am J Trop Med Hyg 2017 97 (4) 1243-1246 Toxocariasis, one of a group of parasitic diseases known as neglected parasitic infections, is a disease caused by the larvae of two species of Toxocara roundworms, Toxocara canis, from dogs, and less commonly Toxocara cati, from cats. Although most infected individuals are asymptomatic, clinical manifestations may include fever, fatigue, coughing, wheezing, or abdominal pain (visceral toxocariasis) or vision loss, retina damage, or eye inflammation (ocular toxocariasis). To assess U.S. pediatrician knowledge of toxocariasis, we conducted an electronic survey of American Academy of Pediatrics members. Of the 2,684 respondents, 1,120 (47%) pediatricians correctly selected toxocariasis as the diagnosis in an unknown case presentation with findings typical for toxocariasis; overall 1,695 (85%) stated they were not confident that their knowledge of toxocariasis was current. This knowledge gap suggests a need for improved toxocariasis awareness and education for U.S. pediatricians, especially those caring for children at risk for infection. |
Individual and community influences on adherence to directives in the event of a plague attack: survey results
Wray RJ , Harris JK , Jupka K , Vijaykumar S , Mitchell EW , Pollard W , Zielinski-Gutierrez E , Reissman D , Lubell K . Disaster Med Public Health Prep 2012 6 (3) 253-62 OBJECTIVES: During a public health emergency, public health officials issue directives with actions people need to take to protect themselves. Past research has shown that adherence to these directives depends on individual beliefs and circumstances. This report presents new research about the effects of community factors on adherence. METHODS: A random digit-dial survey of 936 residents in the St Louis, Missouri, area was conducted in 2008 to assess barriers to and facilitators of adherence to directives issued in response to a hypothetical scenario involving the intentional release of the bacterium that causes plague. Community factors were assessed using characteristics of census tracts for individual respondents. Multilevel modeling was used to understand how individual and community factors contributed to the likelihood of adherence. RESULTS:The majority of participants indicated that they would adhere to 3 distinct directives. Community poverty and ethnic homogeneity as well as individual-level barriers were negatively associated with adherence to a 6-day quarantine. Having children younger than 18 years and being away from home when the directive was called were negatively associated with adherence to a 10-hour quarantine. Logistical concerns were negatively associated with visiting a point of dispensing for prophylactic antibiotics. CONCLUSIONS: Our findings establish an empirical basis for the influence of community factors on adherence to public health directives. The influence of community and individual factors on adherence varies across directives. Consequently, communication strategies to disseminate directives and organizational strategies to support them must vary according to the nature of the directives. |
