Performance of a whole blood immunoassay for tenofovir detection and correlation with self-reported pre-exposure prophylaxis use in HIV-negative men who have sex with men interested in blood donation
Buccheri R , Whitaker B , Pollack LM , Bhaskar JR , Di Germanio C , Guillon G , Haaland R , Stramer SL , Reik R , Pandey S , Stone M , Anderson SA , Marks P , Custer B . Transfusion 2025 BACKGROUND: In 2023, the United States Food and Drug Administration revised its blood donor eligibility policy for men who have sex with men (MSM) from a 3-month deferral to individual assessment. Human Immunodeficiency Virus (HIV) pre-exposure prophylaxis (PrEP) use remains a reason for deferral, and nondisclosure is a concern. STUDY DESIGN AND METHODS: In a cross-sectional study of sexually active MSM from 8 U.S. cities who were interested in future blood donation, we assessed the performance of an enzyme-linked immunosorbent assay for detecting tenofovir (TFV) in whole blood (WB) and plasma and the correlation with self-reported PrEP use. RESULTS: Of 1548 individuals, 48% reported oral PrEP use. The WB assay identified 95% of PrEP users, while the plasma assay detected 88%. The WB assay performed well up to 14 days after the last reported dose. Receiver operating characteristics curve analysis showed an area under the curve of 0.96 (95% confidence interval [CI]: 0.95-0.97) using WB and 0.88 (95% CI: 0.86-0.90) using plasma. Specificity was 80% for WB and 66% for plasma. Detection rates for TFV disoproxil fumarate/emtricitabine (FTC) formulations were 99% in WB and 98% in plasma, compared to 93% and 86% for the TFV alafenamide/FTC formulation. DISCUSSION: High concordance between self-reported oral PrEP use and TFV detection was observed among PrEP users, suggesting the potential utility of WB as a biomatrix for TFV detection to support screening strategies. Given the expanded eligibility for MSM, who may be PrEP users, to donate blood, further examination of undisclosed PrEP use is important. |
Health care use and expenditures associated with cardiac rehabilitation among eligible Medicare fee-for-service beneficiaries
Pollack LM , Chang A , Lee JS , Shaffer T , Wall HK , Brawner CA , Thompson MP , Keteyian SJ , Sukul D , Luo F , Jackson SL . J Am Heart Assoc 2025 e037811 BACKGROUND: Cardiac rehabilitation (CR) can improve cardiovascular health. We identified whether CR participation was associated with fewer subsequent inpatient hospitalizations and emergency department visits and less Medicare and out-of-pocket expenditures, and whether outcomes varied by amount of participation. METHODS: This retrospective study used Medicare fee-for-service claims data, including beneficiaries with a CR-qualifying event in 2016. Participants attended ≥2 sessions of CR within 365 days of the event. Propensity score matching was used to identify CR-eligible nonparticipants. Difference-in-differences analyses were used to compare differences in outcomes before (2014-2015) and after (2018-2019; 2-year CR period=2016-2017) the CR period between participants and nonparticipants. RESULTS: We identified 57 668 CR-eligible beneficiaries after matching, with equal numbers of participants and nonparticipants. Nearly 65% of beneficiaries had a percutaneous coronary intervention, 33.5% had an acute myocardial infarction, 17.5% had a coronary artery bypass graft, and 16.8% had a heart valve repair/replacement. Compared with nonparticipants, participants had 47.6 fewer subsequent annual inpatient hospitalizations per 1000 beneficiaries (95% CI, -58.8 to -36.3) and $1005 lower subsequent annual Medicare expenditures per beneficiary (95% CI, -$1352 to -$659). Compared with no participation, medium participation (12-23 sessions), high participation (24-35 sessions), and CR completion (≥36 sessions) were associated with fewer inpatient hospitalizations and lower Medicare expenditures per year. CONCLUSIONS: CR was associated with fewer subsequent annual inpatient hospitalizations and lower subsequent annual Medicare expenditures. A higher amount of participation was associated with a further reduction in hospitalizations and expenditures. These findings can inform programs and policies that encourage CR participation. |
Hospital-level variation in cardiac rehabilitation metrics
Pollack LM , Chang A , Thompson MP , Keteyian SJ , Stolp H , Wall HK , Sperling LS , Jackson SL . Am Heart J 2024 BACKGROUND: To inform the delivery of cardiac rehabilitation (CR) care nationwide at the hospital level, we described hospital-level variation in CR metrics, overall and stratified by the hospital's tier of cardiac care provided. METHODS: This retrospective cohort analysis used Medicare fee-for-service (FFS) data (2018-2020), Parts A and B, and American Hospital Association (AHA) data (2018). We included beneficiaries with an acute myocardial infarction (AMI), percutaneous coronary intervention (PCI), or coronary artery bypass graft (CABG) in 2018, aged ≥65 years, and continuously enrolled in a FFS plan. We calculated hospital-level metrics for hospitals with ≥20 CR-qualifying events, which were identified using diagnostic/procedure codes. Claims for CR were identified by Healthcare Common Procedure Coding System (HCPCS) codes. We used multi-level models to examine patient- and hospital-level factors associated with CR metrics. Hospitals were stratified by tier of cardiac care provided (comprehensive, AMI/PCI, AMI-only care). RESULTS: Across the US, 2,212 hospitals treated individuals aged ≥65 years with a CR-qualifying event in 2018. By tier of cardiac care, 44.4% of hospitals provided comprehensive care, 31.2% provided AMI/PCI care, and 24.4% provided AMI-only care. Across all hospitals, there was substantial variation in CR enrollment (median 19.6%, interquartile range [IQR]=7.0%, 32.8%). Among hospitals with enrollment (n=1,866), median time to enrollment was 55.0 days (IQR=41.0, 71.0), median number of CR sessions was 26.0 (IQR=23.0, 29.0), and median percent completion was 26.0% (IQR=10.5%, 41.2%). There was also substantial variation in CR performance metrics among hospitals within each tier of cardiac care (e.g., median percent CR enrollment was 30.7% [IQR=20.7%-41.3%] among comprehensive care hospitals, 18.6% [IQR=9.5%-27.7%] among AMI/PCI hospitals, and 0.0% [IQR=0.0%-7.7%] among AMI-only hospitals). In adjusted analyses, characteristics associated with lower odds of CR enrollment included patient-level factors (older age, female sex, non-White race or ethnicity), and hospital-level factors (for-profit ownership, regions other than the Midwest, rural location, medium/large hospital size). CONCLUSIONS: This is the first national, hospital-level analysis of CR metrics among Medicare beneficiaries. Substantial variation across hospitals, including peer hospitals within the same tier of cardiac care, indicates opportunities for hospital-level quality improvement strategies to improve CR referral and participation metrics. |
Costs and healthcare utilization of heart disease by COVID-19 diagnosis and race and ethnicity
Lee JS , Zhang YX , Pollack LM , Luo F . AJPM Focus 2025 4 (1) Introduction: Heart disease poses a significant health and economic burden in the U.S., with considerable variations in outcomes across different racial and ethnic groups. The COVID-19 pandemic has further highlighted the disparities in healthcare utilization and costs associated with heart disease. Methods: The authors used the 2021 Merative MarketScan Medicaid claims database to estimate the medical costs and healthcare utilization associated with heart disease by racial and ethnic groups and COVID-19 diagnosis status. This study focused on individuals aged ≥18 years continuously enrolled in a noncapitated insurance plan in 2021. The outcome measures included total medical expenditures and healthcare utilization, including the numbers of emergency department visits and inpatient admissions and length of inpatient stay. The authors employed a generalized linear model with a family of gamma and log links for medical costs, and a negative binomial regression was used for healthcare utilization. Three-way interactions of heart disease, COVID-19 diagnosis, and race and ethnicity categories were implemented after adjusting for age, sex, and comorbidities. The authors reported average marginal effects with 95% CIs. Results: Among 1,008,166 Medicaid beneficiaries, 8% had heart disease in 2021. The cost associated with heart disease was $10,819 per beneficiary in 2021 (95% CI=10,292; 11,347; p<0.001). The cost was $15,840 (95% CI=14,389; 17,291; p<0.001) for non-Hispanic Black individuals; $9,945 (95% CI=9,172; 10,718; p<0.001) for non-Hispanic White; and $8,511 (95% CI=7,490; 9,531; p<0.001) for Hispanic individuals. Individuals with a COVID-19 diagnosis ($19,638) had $9,541 (95% CI=7,049; 12,032; p<0.001) higher costs associated with heart disease than those without COVID-19 ($10,098) (p<0.001). Individuals with heart disease had higher numbers of emergency department visits (0.937 per beneficiary, 95% CI=0.913; 0.960), inpatient admissions (0.463 per beneficiary, 95% CI=0.455; 0.471), and average length of stay (2.541 days per admission, 95% CI=2.405; 2.677) than those without heart disease. Conclusions: The study's findings showed that costs and healthcare utilization associated with heart disease are substantial in all racial and ethnic groups and the highest among non-Hispanic Black individuals. Furthermore, individuals with a COVID-19 diagnosis had approximately 2 times higher costs associated with heart disease than individuals without a COVID-19 diagnosis. © 2024 |
Antihypertensive medication adherence and medical costs, health care use, and labor productivity among people with hypertension
Lee JS , Segura Escano R , Therrien NL , Kumar A , Bhatt A , Pollack LM , Jackson SL , Luo F . J Am Heart Assoc 2024 13 (21) e037357 BACKGROUND: Hypertension affects nearly half of US adults yet remains inadequately controlled in over three-quarters of these cases. This study aimed to assess the association between adherence to antihypertensive medications and total medical costs, health care use, and productivity-related outcomes. METHODS AND RESULTS: We conducted cross-sectional analyses using MarketScan databases, which included individuals aged 18 to 64 years with noncapitated health insurance plans in 2019. Adherence was defined as ≥80% medication possession ratio for prescribed antihypertensive medications. We used a generalized linear model to estimate total medical costs, a negative binomial model to estimate health care use (emergency department visits and inpatient admissions), an exponential hurdle model to estimate productivity-related outcomes (number of sick absences, short-term disability, long-term disability), and a 2-part model to estimate productivity-related costs in 2019 US dollars. All models were adjusted for age, sex, urbanicity, census region, and comorbidities. We reported average marginal effects for outcomes related to antihypertensive medication adherence. Among 379 503 individuals with hypertension in 2019, 54.4% adhered to antihypertensives. Per person, antihypertensive medication adherence was associated with $1441 lower total medical costs, $11 lower sick absence costs, $291 lower short-term disability costs, and $69 lower long-term disability costs. Per 1000 individuals, medication adherence was associated with lower health care use, including 200 fewer emergency department visits and 90 fewer inpatient admissions, and productivity-related outcomes, including 20 fewer sick absence days and 442 fewer short-term disability days. CONCLUSIONS: Adherence to antihypertensives was consistently associated with lower total medical costs, reduced health care use, and improved productivity-related outcomes. |
Hypertension-associated expenditures among privately insured US adults in 2021
Kumar A , He S , Pollack LM , Lee JS , Imoisili O , Wang Y , Kompaniyets L , Luo F , Jackson SL . Hypertension 2024 BACKGROUND: There are no recent estimates for hypertension-associated medical expenditures. This study aims to estimate hypertension-associated incremental medical expenditures among privately insured US adults. METHODS: We conducted a retrospective cohort study using IQVIA's Ambulatory Electronic Medical Records-US data set linked with PharMetrics Plus claims data. Among privately insured adults aged 18 to 64 years, hypertension was identified as having ≥1 diagnosis code or ≥2 blood pressure measurements of ≥140/90 mm Hg, or ≥1 antihypertensive medication in 2021. Annual total expenditures (in 2021 $US) were estimated using a generalized linear model with gamma distribution and log-link function adjusting for demographic characteristics and cooccurring conditions. Out-of-pocket expenditures were estimated using a 2-part model that included logistic and generalized linear model regression. Overlap propensity score weights from logistic regression were used to obtain a balanced sample on hypertension status. RESULTS: Among the 393 018 adults, 156 556 (40%) were identified with hypertension. Compared with individuals without hypertension, those with hypertension had $2926 (95% CI, $2681-$3170) higher total expenditures and $328 (95% CI, $300-$355) higher out-of-pocket expenditures. Adults with hypertension had higher total inpatient ($3272 [95% CI, $1458-$5086]) and outpatient ($2189 [95% CI, $2009-$2369]) expenditures when compared with those without hypertension. Hypertension-associated incremental total expenditures were higher for women ($3242 [95% CI, $2915-$3569]) than for men ($2521 [95% CI, $2139-$2904]). CONCLUSIONS: Among privately insured US adults, hypertension was associated with higher medical expenditures, including higher inpatient and out-of-pocket expenditures. These findings may help assess the economic value of interventions effective in preventing hypertension. |
Impact of state telehealth parity laws for private payers on hypertension medication adherence before and during the COVID-19 pandemic
Zhang D , Lee JS , Popoola A , Lee S , Jackson SL , Pollack LM , Dong X , Therrien NL , Luo F . Circ Cardiovasc Qual Outcomes 2024 e010739 BACKGROUND: Telehealth has emerged as an effective tool for managing common chronic conditions such as hypertension, especially during the COVID-19 pandemic. However, the impact of state telehealth payment and coverage parity laws on hypertension medication adherence remains uncertain. METHODS: Data from the 2016 to 2021 Merative MarketScan Commercial Claims and Encounters Database were used to construct the study cohort, which included nonpregnant individuals aged 25 to 64 years with hypertension. We coded telehealth parity laws related to hypertension management in all 50 US states and the District of Columbia, distinguishing between payment and coverage parity laws. The primary outcomes were measures of antihypertension medication adherence: the average medication possession ratio; medication adherence (medication possession ratio ≥80%); and average number of days of drug supply. We used a generalized difference-in-differences design to examine the impact of these laws. RESULTS: Among 353 220 individuals (mean [SD] age, 49.5 (7.1) years; female, 45.55%), states with payment parity laws were significantly linked to increased average medication possession ratio by 0.43 percentage point (95% CI, 0.07-0.79), and an increase of 0.46 percentage point (95% CI, 0.06-0.92) in the probability of medication adherence. Payment parity laws also led to an average increase of 2.14 days (95% CI, 0.11-4.17) in prescription supply, after controlling for state-fixed effects, year-fixed effects, individual sociodemographic characteristics and state time-varying covariates including unemployment rates, gross domestic product per capita, and poverty rates. In contrast, coverage parity laws were associated with a 2.13-day increase (95% CI, 0.19-4.07) in days of prescription supply but did not significantly increase the average medication possession ratio or probability of medication adherence. CONCLUSIONS: State telehealth payment parity laws were significantly associated with greater medication adherence, whereas coverage parity laws were not. With the increasing adoption of telehealth parity laws across states, these findings may support policymakers in understanding potential implications on management of hypertension. |
Health care expenditures and use associated with hypertension among U.S. Adults
Wang Y , Lee JS , Pollack LM , Kumar A , Honeycutt S , Luo F . Am J Prev Med 2024 INTRODUCTION: This study seeks to estimate health care expenditures and use associated with hypertension, focusing on differences among racial and ethnic groups. METHODS: Data were from the 2019 Medical Expenditure Panel Survey, analyzed in 2023. The study sample included noninstitutionalized U.S. adults aged ≥18 years. Outcome variables were health care expenditures and events. Hypertension was determined by a self-reported diagnosis or diagnoses codes. Race and ethnicity were self-reported. A 2-part model was used to estimate expenditures associated with hypertension. A zero-inflated negative binomial model was used to estimate events associated with hypertension. Sampling designs were applied to generate nationally representative estimates. RESULTS: Hypertension was associated with $2,759 (95% confidence interval [CI]: $2,039, $3,479) in health care expenditures and 10.3 (95% CI: 9.3, 11.3) health care events, including prescriptions filled, in 2019 per person. Compared with non-Hispanic White adults, hypertension-associated health care expenditures were significantly lower among Hispanic adults (difference: -$1,877; 95% CI: -$3,389, -$364) and Asian adults (difference: -$2,452; 95% CI: -$4,093, -$811), and hypertension-associated health care events were significantly lower among Hispanic adults (difference: -3.8; 95% CI: -6.1, -1.6) and non-Hispanic Asian adults (difference: -4.1; 95% CI: -6.9, -1.2). Differences between non-Hispanic White adults and non-Hispanic Black adults were not statistically significant in health care expenditures (difference: -$954; 95% CI: -$2,849, $941) and events (difference: 0.3; 95% CI: -2.1, 2.8). CONCLUSIONS: This study reveals differences in health care expenditures and use associated with hypertension among racial and ethnic groups. Future studies are needed to examine potential drivers of these differences. |
County-level cardiac rehabilitation and broadband availability: Opportunities for hybrid care in the United States
DeLara DL , Pollack LM , Wall HK , Chang A , Schieb L , Matthews K , Stolp H , Pack QR , Casper M , Jackson SL . J Cardiopulm Rehabil Prev 2024 PURPOSE: Cardiac rehabilitation (CR) improves patient outcomes and quality of life and can be provided virtually through hybrid CR. However, little is known about CR availability in conjunction with broadband access, a requirement for hybrid CR. This study examined the intersection of CR and broadband availability at the county level, nationwide. METHODS: Data were gathered and analyzed in 2022 from the 2019 American Community Survey, the Centers for Medicare & Medicaid Services, and the Federal Communications Commission. Spatially adaptive floating catchments were used to calculate county-level percent CR availability among Medicare fee-for-service beneficiaries. Counties were categorized: by CR availability, whether lowest (ie, CR deserts), medium, or highest; and by broadband availability, whether CR deserts with majority-available broadband, or dual deserts. Results were stratified by state. County-level characteristics were examined for statistical significance by CR availability category. RESULTS: Almost half of US adults (n = 116 325 976, 47.2%) lived in CR desert counties (1691 counties). Among adults in CR desert counties, 96.8% were in CR deserts with majority-available broadband (112 626 906). By state, the percentage of the adult population living in CR desert counties ranged from 3.2% (New Hampshire) to 100% (Hawaii and Washington, DC). Statistically significant differences in county CR availability existed by race/ethnicity, education, and income. CONCLUSIONS: Almost half of US adults live in CR deserts. Given that up to 97% of adults living in CR deserts may have broadband access, implementation of hybrid CR programs that include a telehealth component could expand CR availability to as many as 113 million US adults. |
Association of economic policies with hypertension management and control: A systematic review
Zhang D , Lee JS , Pollack LM , Dong X , Taliano JM , Rajan A , Therrien NL , Jackson SL , Popoola A , Luo F . JAMA Health Forum 2024 5 (2) e235231 IMPORTANCE: Economic policies have the potential to impact management and control of hypertension. OBJECTIVES: To review the evidence on the association between economic policies and hypertension management and control among adults with hypertension in the US. EVIDENCE REVIEW: A search was carried out of PubMed/MEDLINE, Cochrane Library, Embase, PsycINFO, CINAHL, EconLit, Sociological Abstracts, and Scopus from January 1, 2000, through November 1, 2023. Included were randomized clinical trials, difference-in-differences, and interrupted time series studies that evaluated the association of economic policies with hypertension management. Economic policies were grouped into 3 categories: insurance coverage expansion such as Medicaid expansion, cost sharing in health care such as increased drug copayments, and financial incentives for quality such as pay-for-performance. Antihypertensive treatment was measured as taking antihypertensive medications or medication adherence among those who have a hypertension diagnosis; and hypertension control, measured as blood pressure (BP) lower than 140/90 mm Hg or a reduction in BP. Evidence was extracted and synthesized through dual review of titles, abstracts, full-text articles, study quality, and policy effects. FINDINGS: In total, 31 articles were included. None of the studies examined economic policies outside of the health care system. Of these, 16 (52%) assessed policies for insurance coverage expansion, 8 (26%) evaluated policies related to patient cost sharing for prescription drugs, and 7 (22%) evaluated financial incentive programs for improving health care quality. Of the 16 studies that evaluated coverage expansion policies, all but 1 found that policies such as Medicare Part D and Medicaid expansion were associated with significant improvement in antihypertensive treatment and BP control. Among the 8 studies that examined patient cost sharing, 4 found that measures such as prior authorization and increased copayments were associated with decreased adherence to antihypertensive medication. Finally, all 7 studies evaluating financial incentives aimed at improving quality found that they were associated with improved antihypertensive treatment and BP control. Overall, most studies had a moderate or low risk of bias in their policy evaluation. CONCLUSIONS AND RELEVANCE: The findings of this systematic review suggest that economic policies aimed at expanding insurance coverage or improving health care quality successfully improved medication use and BP control among US adults with hypertension. Future research is needed to investigate the potential effects of non-health care economic policies on hypertension control. |
Racial and ethnic differences in hypertension-related telehealth and in-person outpatient visits before and during the COVID-19 pandemic among Medicaid Beneficiaries
Lee JS , Bhatt A , Pollack LM , Jackson SL , Omeaku N , Lowe Beasley K , Wilson C , Luo F , Roy K . Telemed J E Health 2024 Background: Little is known about the trends and costs of hypertension management through telehealth among individuals enrolled in Medicaid. Methods: Using MarketScan(®) Medicaid database, we examined outpatient visits among people with hypertension aged 18-64 years. We presented the numbers of hypertension-related telehealth and in-person outpatient visits per 100 individuals and the proportion of hypertension-related telehealth outpatient visits to total outpatient visits by month, overall, and by race and ethnicity. For the cost analysis, we presented total and patient out-of-pocket (OOP) costs per visit for telehealth and in-person visits in 2021. Results: Of the 229,562 individuals, 114,445 (49.9%) were non-Hispanic White, 80,692 (35.2%) were non-Hispanic Black, 3,924 (1.71%) were Hispanic. From February to April 2020, the number of hypertension-related telehealth outpatient visits per 100 persons increased from 0.01 to 6.13, the number of hypertension-related in-person visits decreased from 61.88 to 52.63, and the proportion of hypertension-related telehealth outpatient visits increased from 0.01% to 10.44%. During that same time, the proportion increased from 0.02% to 13.9% for non-Hispanic White adults, from 0.00% to 7.58% for non-Hispanic Black adults, and from 0.12% to 19.82% for Hispanic adults. The average total and patient OOP costs per visit in 2021 were $83.82 (95% confidence interval [CI], 82.66-85.05) and $0.55 (95% CI, 0.42-0.68) for telehealth and $264.48 (95% CI, 258.87-269.51) and $0.72 (95% CI, 0.65-0.79) for in-person visits, respectively. Conclusions: Hypertension management via telehealth increased among Medicaid recipients regardless of race and ethnicity, during the COVID-19 pandemic. These findings may inform telehealth policymakers and health care practitioners. |
Rural and urban differences in hypertension management through telehealth before and during the COVID-19 pandemic among commercially insured patients
Lee JS , Bhatt A , Jackson SL , Pollack LM , Omeaku N , Lowe K , Wilson C , Luo F , Roy K . Am J Hypertens 2023 BACKGROUND: The COVID-19 pandemic prompted a rapid increase in telehealth use. However, limited evidence exists on how rural and urban residents used telehealth and in-person outpatient services to manage hypertension during the pandemic. METHODS: This longitudinal study analyzed 701,410 US adults (18-64 years) in the MarketScan Commercial Claims Database, who were continuously enrolled from January 2017 through March 2022. We documented monthly numbers of hypertension-related telehealth and in-person outpatient visits (per 100 individuals), and the proportion of telehealth visits among all hypertension-related outpatient visits, from January 2019 through March 2022. We used Welch's 2-tail t-test to differentiate monthly estimates by rural-urban status and month-to-month changes. RESULTS: From February through April 2020, the monthly number of hypertension-related telehealth visits per 100 individuals increased from 0.01 to 6.05 (P<0.001) for urban residents and from 0.01 to 4.56 (P<0.001) for rural residents. Hypertension-related in-person visits decreased from 20.12 to 8.30 (P<0.001) for urban residents and from 20.48 to 10.15 (P<0.001) for rural residents. The proportion of hypertension-related telehealth visits increased from 0.04% to 42.15% (P<0.001) for urban residents and from 0.06% to 30.98% (P<0.001) for rural residents. From March 2020 to March 2022, the monthly average of the proportions of hypertension-related telehealth visits was higher for urban residents than for rural residents (10.19% vs. 6.96%; P<0.001). CONCLUSIONS: Data show that rural residents were less likely to use telehealth for hypertension management. Understanding trends in hypertension-related telehealth utilization can highlight disparities in the sustained use of telehealth to advance accessible health care. |
HIV risk behavior profiles among men who have sex with men interested in donating blood: Findings from the Assessing Donor Variability and New Concepts in Eligibility study
Custer B , Whitaker BI , Pollack LM , Buccheri R , Bruhn RL , Crowder LA , Stramer SL , Reik RA , Pandey S , Stone M , Di Germanio C , Buchacz K , Eder AF , Lu Y , Forshee RA , Anderson SA , Marks PW . Transfusion 2023 63 (10) 1872-1884 BACKGROUND: Individual risk assessment allows donors to be evaluated based on their own behaviors. Study objectives were to assess human immunodeficiency virus (HIV) risk behaviors in men who have sex with men (MSM) and estimate the proportion of the study population who would not be deferred for higher risk HIV sexual behaviors. STUDY DESIGN AND METHODS: Cross-sectional survey and biomarker assessment were conducted in eight U.S. cities. Participants were sexually active MSM interested in blood donation aged 18-39 years, assigned male sex at birth. Participants completed surveys during two study visits to define eligibility, and self-reported sexual and HIV prevention behaviors. Blood was drawn at study visit 1 and tested for HIV and the presence of tenofovir, one of the drugs in oral HIV pre-exposure prophylaxis (PrEP). Associations were assessed between HIV infection status or HIV PrEP use and behaviors, including sex partners, new partners, and anal sex. RESULTS: A total of 1566 MSM completed the visit 1 questionnaire and blood draw and 1197 completed the visit 2 questionnaire. Among 1562 persons without HIV, 789 (50.4%) were not taking PrEP. Of those not taking PrEP, 66.2% reported one sexual partner or no anal sex and 69% reported no new sexual partners or no anal sex with a new partner in the past 3 months. CONCLUSION: The study found that questions were able to identify sexually active, HIV-negative MSM who report lower risk sexual behaviors. About a quarter of enrolled study participants would be potentially eligible blood donors using individual risk assessment questions. |
Rural/urban differences in health care utilization and costs by perinatal depression status among commercial enrollees
Pollack LM , Chen J , Cox S , Luo F , Robbins CL , Tevendale H , Li R , Ko JY . J Rural Health 2023 40 (1) 26-63 PURPOSE: To understand differences in health care utilization and medical expenditures by perinatal depression (PND) status during pregnancy and 1-year postpartum overall and by rural/urban status. METHODS: We estimated differences in health care utilization and medical expenditures by PND status for individuals with an inpatient live-birth delivery in 2017, continuously enrolled in commercial insurance from 3 months before pregnancy through 1-year postpartum (study period), using MarketScan Commercial Claims data. Multivariable regression was used to examine differences by rurality. FINDINGS: Ten percent of commercially insured individuals had claims with PND. A smaller proportion of rural (8.7%) versus urban residents (10.0%) had a depression diagnosis (p < 0.0001). Of those with PND, a smaller proportion of rural (5.5%) versus urban residents (9.6%) had a depression claim 3 months before pregnancy (p < 0.0001). Compared with urban residents, rural residents had greater differences by PND status in total inpatient days (rural: 0.7, 95% confidence interval [CI]: 0.6-0.9 vs. urban: 0.5, 95% CI: 0.5-0.6) and emergency department (ED) visits (rural: 0.7, 95% CI: 0.6-0.9 vs. urban: 0.5, 95% CI: 0.4-0.5), but a smaller difference by PND status in the number of outpatient visits (rural: 9.2, 95% CI: 8.2-10.2 vs. urban: 13.1, 95% CI: 12.7-13.5). Differences in expenditures for inpatient services by PND status differed by rural/urban status (rural: $2654; 95% CI: $1823-$3485 vs. urban: $1786; 95% CI: $1445-$2127). CONCLUSIONS: Commercially insured rural residents had more utilization for inpatient and ED services and less utilization for outpatient services. Rural locations can present barriers to evidence-based care to address PND. |
Timing of outpatient postpartum care utilization among women with chronic hypertension and hypertensive disorders of pregnancy
Aqua JK , Ford ND , Pollack LM , Lee JS , Kuklina EV , Hayes DK , Vaughan AS , Coronado F . Am J Obstet Gynecol MFM 2023 5 (9) 101051 BACKGROUND: The postpartum period represents an opportunity to assess the cardiovascular health of women who experience chronic hypertension or hypertensive disorders of pregnancy. OBJECTIVES: To determine whether women with chronic hypertension or hypertensive disorders of pregnancy access outpatient postpartum care more quickly compared to women with no hypertension. STUDY DESIGN: We used data from the Merative MarketScan® Commercial Claims and Encounters Database. We included 275,937 commercially insured women aged 12-55 years who had a live birth or stillbirth delivery hospitalization between 2017-2018 and continuous insurance enrollment from 3 months before the estimated start of pregnancy to 6 months after delivery discharge. Using International Classification of Diseases 10th Revision Clinical Modification codes, we identified hypertensive disorders of pregnancy from inpatient or outpatient claims from 20 weeks gestation through delivery hospitalization and identified chronic hypertension from inpatient or outpatient claims from the beginning of the continuous enrollment period through delivery hospitalization. Distributions of time-to-event survival curves (time-to-first outpatient postpartum visit with a women's health, primary care, or cardiology provider) were compared between the hypertension types using Kaplan-Meier estimators and log rank tests. We used Cox proportional hazards models to estimate adjusted hazard ratios (aHR) and 95% confidence intervals (CI). Time points of interest (3, 6, and 12 weeks) were evaluated per clinical postpartum care guidelines. RESULTS: Among commercially insured women, the prevalences of hypertensive disorders of pregnancy, chronic hypertension, and no documented hypertension were 11.7%, 3.4%, and 84.8%, respectively. The proportions of women with a visit within 3 weeks of delivery discharge were 28.5%, 26.4%, and 16.0% for hypertensive disorders of pregnancy, chronic, and no documented hypertension, respectively. By 12 weeks, the proportions increased to 62.4%, 64.5%, and 54.2%, respectively. Kaplan-Meier analyses indicated significant differences in utilization by hypertension type and interaction between hypertension type and time before and after 6 weeks. In adjusted Cox proportional hazards models, the utilization rate before 6 weeks among women with hypertensive disorders of pregnancy was 1.42 times the rate for women with no documented hypertension [aHR=1.42, 95% CI (1.39-1.45)]. Women with chronic hypertension also had higher utilization rates compared to women with no documented hypertension before 6 weeks [aHR=1.28, 95% CI: (1.24-1.33)]. Only chronic hypertension was significantly associated with utilization compared to the no documented hypertension group after 6 weeks [aHR=1.09, 95% CI: (1.03-1.14)]. CONCLUSIONS: In the 6 weeks following delivery discharge, women with hypertensive disorders of pregnancy and chronic hypertension attended outpatient postpartum care visits sooner than women with no documented hypertension. However, after 6 weeks this difference extended only to women with chronic hypertension. Overall, postpartum care utilization remained around 50-60% by 12 weeks in all groups. Addressing barriers to postpartum care attendance can ensure timely care for women at high risk for cardiovascular disease. |
Healthcare utilization and costs associated with perinatal depression among Medicaid enrollees
Pollack LM , Chen J , Cox S , Luo F , Robbins CL , Tevendale HD , Li R , Ko JY . Am J Prev Med 2022 62 (6) e333-e341 INTRODUCTION: Differences in healthcare utilization and medical expenditures associated with perinatal depression are estimated. METHODS: Using the MarketScan Multi-State Medicaid Database, the analytic cohort included individuals aged 15-44 years who had an inpatient live birth delivery hospitalization between January 1, 2017 and December 31, 2018. Multivariable negative binomial regression models were used to estimate the differences in utilization associated with perinatal depression, and multivariable generalized linear models were used to estimate the differences in expenditures associated with perinatal depression. Analyses were conducted in 2021. RESULTS: The cohort included 330,593 individuals. Nearly 17% had perinatal depression. Compared with individuals without perinatal depression individuals with perinatal depression had a larger number of inpatient admissions (0.19, 95% CI=0.18, 0.20), total inpatient days (0.95, 95% CI=0.92, 0.97), outpatient visits (14.02, 95% CI=13.81, 14.22), emergency department visits (1.70, 95% CI=1.66, 1.74), and weeks of drug therapy covered by a prescription (28.70, 95% CI=28.12, 29.28) and larger total expenditures ($5,078, 95% CI=$4,816, $5,340). Non-Hispanic Black individuals had larger differences in utilization and expenditures for inpatient services and outpatient visits but smaller differences in utilization for pharmaceutical services associated with perinatal depression than non-Hispanic White individuals. Hispanic individuals had larger differences in utilization for outpatient visits but smaller differences in utilization for pharmaceutical services associated with perinatal depression than non-Hispanic White individuals. CONCLUSIONS: Individuals with perinatal depression had more healthcare utilization and medical expenditures than individuals without perinatal depression, and differences varied by race/ethnicity. The findings highlight the need to ensure comprehensive and equitable mental health care to address perinatal depression. |
Estimating the impact of increasing cervical cancer screening in the National Breast and Cervical Cancer Early Detection Program among low-income women in the USA
Pollack LM , Ekwueme DU , Hung MC , Miller JW , Chang SH . Cancer Causes Control 2020 31 (7) 691-702 PURPOSE: The National Breast and Cervical Cancer Early Detection Program (NBCCEDP) provides free cervical cancer screening to low-income women. This study estimated the health benefits gained in terms of life years (LYs) saved and quality-adjusted life years (QALYs) gained if cervical cancer screening by the NBCCEDP increased to reach more eligible women. METHODS: Data from Surveillance, Epidemiology, and End Results, NBCCEDP, and Medical Expenditure Panel Surveys were used. LYs saved and QALYs gained/100,000 women were estimated using modeling methods. They were used to predict additional health benefits gained if screening by the NBCCEDP increased from 6.5% up to 10-25% of the eligible women. RESULTS: Overall, per 100,000 women screened by the NBCCEDP, 1,731 LYs were saved and 1,608 QALYs were gained. For white women, 1,926 LYs were saved and 1,780 QALYs were gained/100,000 women screened by the NBCCEDP. For black women, 1,506 LYs were saved and 1,300 QALYs were gained/100,000 women screened. If the proportion of eligible women screened by the NBCCEDP increased to 10-25%, the estimated health benefits would range from 6,626-34,896 LYs saved and 6,153-32,407 QALYs gained. CONCLUSIONS: The reported estimates emphasize the value of cervical cancer screening program by extending LE in low-income women. Further, it demonstrates that screening a higher percentage of eligible women in the NBCCEDP may yield more health benefits. |

Drug Alcohol Depend 2017 174 106-112 BACKGROUND: Spirituality and religiosity may serve as both a resource and a barrier to HIV prevention with young black men who have sex with men (YBMSM). We examined indices of spirituality/religiosity as correlates of binge drinking, stimulant use, and recent HIV testing in a sample of YBMSM. METHODS: From 2011-2013, annual venue-based surveys of sexually active YBMSM ages 18-29 were conducted in Dallas and Houston, Texas. Binge drinking and stimulant use were assessed in the past two months. Participants recently tested for HIV (i.e., within the past six months) were compared to those without recent HIV testing (i.e., never tested or tested more than six months ago). RESULTS: Among the 1565 HIV-negative or HIV-unknown YBMSM enrolled, more engagement in spiritual and religious activities was associated with greater odds of reporting stimulant use (Adjusted Odds Ratio [AOR]=1.20; 95% CI=1.04-1.40) while higher spiritual coping was associated with lower odds of reporting stimulant use (AOR=0.66; 95% CI=0.56-0.78). Binge drinking was independently associated with 29% lower odds of recent HIV testing (AOR=0.71; 95% CI=0.55-0.92), but lower odds of binge drinking did not mediate the association of engagement in spiritual and religious activities with 27% greater odds of recent HIV testing (AOR=1.27; 95% CI=1.11-1.46). CONCLUSIONS: Among YBMSM, culturally tailored approaches addressing spirituality/religiosity could support prevention of stimulant use and increase HIV testing. In particular, expanded efforts are needed to promote HIV testing in binge drinkers. |
