RESUMEN

Importance: Nursing home residents with Alzheimer disease and related dementias (ADRD) often receive burdensome care at the end of life. Nurse practitioners (NPs) provide an increasing share of primary care in nursing homes, but how NP care is associated with end-of-life outcomes for this population is unknown. Objectives: To examine the association of NP care with end-of-life outcomes for nursing home residents with ADRD and assess whether these associations differ according to state-level NP scope of practice regulations. Design, Setting, and Participants: This cohort study using fee-for-service Medicare claims included 334 618 US nursing home residents with ADRD who died between January 1, 2016, and December 31, 2018. Data were analyzed from April 6, 2015, to December 31, 2018. Exposures: Share of nursing home primary care visits by NPs, classified as minimal (<10% of visits), moderate (10%-50% of visits), and extensive (>50% of visits). State NP scope of practice regulations were classified as full vs restrictive in 2 domains: practice authority (authorization to practice and prescribe independently) and do-not-resuscitate (DNR) authority (authorization to sign DNR orders). Main Outcomes and Measures: Hospitalization within the last 30 days of life and death with hospice. Linear probability models with hospital referral region fixed effects controlling for resident characteristics, visit volume, and geographic factors were used to estimate whether the associations between NP care and outcomes varied across states with different scope of practice regulations. Results: Among 334 618 nursing home decedents (mean [SD] age at death, 86.6 [8.2] years; 69.3% female), 40.5% received minimal NP care, 21.4% received moderate NP care, and 38.0% received extensive NP care. Adjusted hospitalization rates were lower for residents with extensive NP care (31.6% [95% CI, 31.4%-31.9%]) vs minimal NP care (32.3% [95% CI, 32.1%-32.6%]), whereas adjusted hospice rates were higher for residents with extensive (55.6% [95% CI, 55.3%-55.9%]) vs minimal (53.6% [95% CI, 53.3%-53.8%]) NP care. However, there was significant variation by state scope of practice. For example, in full practice authority states, adjusted hospice rates were 2.88 percentage points higher (95% CI, 1.99-3.77; P < .001) for residents with extensive vs minimal NP care, but the difference between these same groups was 1.77 percentage points (95% CI, 1.32-2.23; P < .001) in restricted practice states. Hospitalization rates were 1.76 percentage points lower (95% CI, -2.52 to -1.00; P < .001) for decedents with extensive vs minimal NP care in full practice authority states, but the difference between these same groups in restricted practice states was only 0.43 percentage points (95% CI, -0.84 to -0.01; P < .04). Similar patterns were observed in analyses focused on DNR authority. Conclusions and Relevance: The findings of this cohort study suggest that NPs appear to be important care providers during the end-of-life period for many nursing home residents with ADRD and that regulations governing NP scope of practice may have implications for end-of-life hospitalizations and hospice use in this population.

RESUMEN

Importance: Staffing shortages have been widely reported in US nursing homes during the COVID-19 pandemic, but traditional quantitative research analyses have found mixed evidence of staffing shortfalls. Objective: To examine whether nursing home administrator perspectives can provide context for conflicting aggregate staffing reports in US nursing homes during the COVID-19 pandemic. Design, Setting, and Participants: In a qualitative study, convergent mixed-methods analysis integrating qualitative and quantitative data sets was used. Semistructured qualitative interviews were conducted between July 14, 2020, and December 16, 2021. Publicly available national Payroll Based Journal data were retrieved from January 1, 2020, to September 30, 2022, on 40 US nursing homes in 8 health care markets that varied by region and nursing home use patterns. Staffing and resident measures were derived from Payroll Based Journal data and compared with national trends for 15 436 US nursing homes. Nursing home administrators were recruited for interviews. Of the 40 administrators who consented to participate, 4 were lost to follow-up. Exposure: Four repeated, semistructured qualitative interviews with participants were conducted. Interview questions focused on the changes noted during the COVID-19 pandemic in nursing homes. Main Outcomes and Measures: Thematic description of nursing home administrator compensatory strategies to provide context for quantitative analyses on nursing home staffing levels during the COVID-19 pandemic. Results: A total of 156 interviews were completed with 40 nursing home administrators. Administrators reported experiencing staff shortages during the COVID-19 pandemic and using compensatory strategies, such as overtime, cross-training, staff-to-resident ratio adjustments, use of agency staff, and curtailing admissions, to maintain operations and comply with minimum staffing regulations. Payroll Based Journal data measures graphed from January 1, 2020, to September 30, 2022, supported administrator reports showing that study facilities had reductions in staff hours, increased use of agency staff, and decreased resident census. Findings were similar to national trends. Conclusions and Relevance: In this qualitative, convergent mixed-methods study, nursing home administrators reported the major staffing strain they experienced at their facilities and the strategies they used to offset staffing shortages. Their experiences provide context to quantitative analyses on aggregate nursing home census data. The short-term compensatory measures administrators used to comply with regulations and maintain operations may be detrimental to the long-term stability of this workforce.

RESUMEN

BACKGROUND: Home health services are an important site of care following hospitalization among Medicare beneficiaries, providing health assessments that can be leveraged to detect diagnoses that are not available in other data sources. In this work, we aimed to develop a parsimonious and accurate algorithm using home health outcome and assessment information set (OASIS) measures to identify Medicare beneficiaries with a diagnosis of Alzheimer's disease and related dementia (ADRD). METHODS: We conducted a retrospective cohort study of Medicare beneficiaries with a complete OASIS start of care assessment in 2014, 2016, 2018, or 2019 to determine how well the items from various versions could identify those with an ADRD diagnosis by the assessment date. The prediction model was developed iteratively, comparing the performance of different models in terms of sensitivity, specificity, and accuracy of prediction, from a multivariable logistic regression model using clinically relevant variables, to regression models with all available variables and predictive modeling techniques, to estimate the best performing parsimonious model. RESULTS: The most important predictors of having a diagnosis of ADRD by the start of care OASIS assessment were a prior discharge diagnosis of ADRD among those admitted from an inpatient setting, and frequently exhibiting symptoms of confusion. Results from the parsimonious model were consistent across the four annual cohorts and OASIS versions with high specificity (above 96%), but poor sensitivity (below 58%). The positive predictive value was high, over 87% across study years. CONCLUSIONS: The proposed algorithm has high accuracy, requires a single OASIS assessment, is easy to implement without sophisticated statistical models, and can be used across four OASIS versions and in situations where claims are not available to identify individuals with a diagnosis of ADRD, including the growing population of Medicare Advantage beneficiaries.

RESUMEN

In a multi-payer health care system, economic theory suggests that different payers can impose spillover effects on one another. This study aimed to evaluate the spillover effect of the Patient Driven Payment Model (PDPM) on Medicare Advantage (MA) enrollees, despite it being designed for Traditional Medicare (TM) beneficiaries. We applied a regression discontinuity approach by comparing therapy utilization before and after the implementation of PDPM in October 2019 focusing on patients newly admitted to skilled nursing facilities. The results showed that both TM and MA enrollees experienced a decrease in individual therapy minutes and an increase in non-individual therapy minutes. The estimated reduction in total therapy use was 9 min per day for TM enrollees and 3 min per day for MA enrollees. The effect of PDPM on MA beneficiaries varied depending on the level of MA penetration, with the smallest effect in facilities with the highest MA penetration quartile. In summary, the PDPM had directionally similar effects on therapy utilization for both TM and MA enrollees, but the magnitudes were smaller for MA beneficiaries. These results suggest that policy changes intended for TM beneficiaries may spillover to MA enrollees and should be assessed accordingly.

RESUMEN

INTRODUCTION: Adult day health centers (ADHCs) provide an important service to community-dwelling adults with functional dependency. This includes persons living with dementia (PLWD) and their caregivers, but we don't know how well ADHC capacity matches the distribution of PLWD. METHODS: For this cross-sectional study, we identified community-dwelling PLWD using Medicare claims, and ADHC capacity using licensure data. We aggregated both features by Hospital Service Area. By linear regression, we determined the association between ADHC capacity and community-dwelling PLWD. RESULTS: We identified 3836 community-dwelling Medicare beneficiaries living with dementia. We included 28 ADHCs, with licensed capacity for 2127 clients. The linear regression coefficient (95% Confidence Interval) for number of community-dwelling beneficiaries with dementia was 1.07 (0.6-1.53). DISCUSSION: Rhode Island's ADHC capacity distribution roughly approximates the distribution of persons with dementia. Plans for the future of dementia care in Rhode Island should consider these findings.

RESUMEN

INTRODUCTION: Older adults with Alzheimer's disease and related dementias (ADRD) often face burdensome end-of-life care transfers. Advanced practice clinicians (APCs)-which include nurse practitioners and physician assistants-increasingly provide primary care to this population. To fill current gaps in the literature, we measured the association between APC involvement in end-of-life care versus hospice utilization and hospitalization for older adults with ADRD. METHODS: Using Medicare data, we identified nursing home- (N=517,490) and community-dwelling (N=322,461) beneficiaries with ADRD who died between 2016 and 2018. We employed propensity score-weighted regression methods to examine the association between different levels of APC care during their final 9 months of life versus hospice utilization and hospitalization during their final month. RESULTS: For both nursing home- and community-dwelling beneficiaries, higher APC care involvement associated with lower hospitalization rates and higher hospice rates. DISCUSSION: APCs are an important group of providers delivering end-of-life primary care to individuals with ADRD. HIGHLIGHTS: For both nursing home- and community-dwelling Medicare beneficiaries with ADRD, adjusted hospitalization rates were lower and hospice rates were higher for individuals with higher proportions of APC care involvement during their final 9 months of life. Associations between APC care involvement and both adjusted hospitalization rates and adjusted hospice rates persisted when accounting for primary care visit volume.

RESUMEN

Importance: A SARS-CoV-2 vaccine booster dose has been recommended for all nursing home residents. However, data on the effectiveness of an mRNA vaccine booster in preventing infection, hospitalization, and death in this vulnerable population are lacking. Objective: To evaluate the association between receipt of a SARS-CoV-2 mRNA vaccine booster and prevention of infection, hospitalization, or death among nursing home residents. Design, Setting, and Participants: This cohort study emulated sequentially nested target trials for vaccination using data from 2 large multistate US nursing home systems: Genesis HealthCare, a community nursing home operator (system 1) and Veterans Health Administration community living centers (VHA CLCs; system 2). The cohort included long-term (≥100 days) nursing home residents (10 949 residents from 202 community nursing homes and 4321 residents from 128 VHA CLCs) who completed a 2-dose series of an mRNA vaccine (either BNT162b2 [Pfizer-BioNTech] or mRNA-1273 [Moderna]) and were eligible for a booster dose between September 22 and November 30, 2021. Residents were followed up until March 8, 2022. Exposures: Receipt of a third mRNA vaccine dose, defined as a booster dose (boosted group), or nonreceipt of a booster dose (unboosted group) on an eligible target trial date. If participants in the unboosted group received a booster dose on a later target trial date, they were included in the booster group for that target trial; thus, participants could be included in both the boosted and unboosted groups. Main Outcomes and Measures: Test-confirmed SARS-CoV-2 infection, hospitalization, or death was followed up to 12 weeks after booster vaccination. The primary measure of estimated vaccine effectiveness was the ratio of cumulative incidences in the boosted group vs the unboosted group at week 12, adjusted with inverse probability weights for treatment and censoring. Results: System 1 included 202 community nursing homes; among 8332 boosted residents (5325 [63.9%] female; 6685 [80.2%] White) vs 10 886 unboosted residents (6865 [63.1%] female; 8651 [79.5%] White), the median age was 78 (IQR, 68-87) years vs 78 (IQR, 68-86) years. System 2 included 128 VHA CLCs; among 3289 boosted residents (3157 [96.0%] male; 1950 [59.3%] White) vs 4317 unboosted residents (4151 [96.2%] male; 2434 [56.4%] White), the median age was 74 (IQR, 70-80) vs 74 (IQR, 69-80) years. Booster vaccination was associated with reductions in SARS-CoV-2 infections of 37.7% (95% CI, 25.4%-44.2%) in system 1 and 57.7% (95% CI, 43.5%-67.8%) in system 2. For hospitalization, reductions of 74.4% (95% CI, 44.6%-86.2%) in system 1 and 64.1% (95% CI, 41.3%-76.0%) in system 2 were observed. Estimated vaccine effectiveness for death associated with SARS-CoV-2 was 87.9% (95% CI, 75.9%-93.9%) in system 1; however, although a reduction in death was observed in system 2 (46.6%; 95% CI, -34.6% to 94.8%), this reduction was not statistically significant. A total of 45 SARS-CoV-2-associated deaths occurred in system 1 and 18 deaths occurred in system 2. For the combined end point of SARS-CoV-2-associated hospitalization or death, boosted residents in system 1 had an 80.3% (95% CI, 65.7%-88.5%) reduction, and boosted residents in system 2 had a 63.8% (95% CI, 41.4%-76.1%) reduction. Conclusions and Relevance: In this study, during a period in which both the Delta and Omicron variants were circulating, SARS-CoV-2 booster vaccination was associated with significant reductions in SARS-CoV-2 infections, hospitalizations, and the combined end point of hospitalization or death among residents of 2 US nursing home systems. These findings suggest that administration of vaccine boosters to nursing home residents may have an important role in preventing COVID-19-associated morbidity and mortality.

RESUMEN

Nursing home residents continue to experience significant COVID-19 morbidity and mortality (1). On March 29, 2022, the Advisory Committee on Immunization Practices (ACIP) recommended a second mRNA COVID-19 vaccine booster dose for adults aged ≥50 years and all immunocompromised persons who had received a first booster ≥4 months earlier.* On September 1, 2022, ACIP voted to recommend bivalent mRNA COVID-19 vaccine boosters for all persons aged ≥12 years who had completed the primary series using monovalent vaccines ≥2 months earlier (2). Data on COVID-19 booster dose vaccine effectiveness (VE) in the nursing home population are limited (3). For this analysis, academic, federal, and private partners evaluated routine care data collected from 196 U.S. community nursing homes to estimate VE of a second mRNA COVID-19 vaccine booster dose among nursing home residents who had received 3 previous COVID-19 vaccine doses (2 primary series doses and 1 booster dose). Residents who received second mRNA COVID-19 vaccine booster doses during March 29-June 15, 2022, with follow-up through July 25, 2022, were found to have 60-day VE of 25.8% against SARS-CoV-2 (the virus that causes COVID-19 infection), 73.9% against severe COVID-19 outcomes (a combined endpoint of COVID-19-associated hospitalizations or deaths), and 89.6% against COVID-19-associated deaths alone. During this period, subvariants BA.2 and BA.2.12.1 (March-June 2022), and BA.4 and BA.5 (July 2022) of the B.1.1.529 and BA.2 (Omicron) variant were predominant. These findings suggest that among nursing home residents, second mRNA COVID-19 vaccine booster doses provided additional protection over first booster doses against severe COVID-19 outcomes during a time of emerging Omicron variants. Facilities should continue to ensure that nursing home residents remain up to date with COVID-19 vaccination, including bivalent vaccine booster doses, to prevent severe COVID-19 outcomes.

RESUMEN

Importance: In October 2019, Medicare changed its skilled nursing facility (SNF) reimbursement model to the Patient Driven Payment Model (PDPM), which has modified financial incentives for SNFs that may relate to therapy use and health outcomes. Objective: To assess whether implementation of the PDPM was associated with changes in therapy utilization or health outcomes. Design Setting and Participants: This cross-sectional study used a regression discontinuity (RD) approach among Medicare fee-for-service postacute-care patients admitted to a Medicare-certified SNF following hip fracture between January 2018 and March 2020. Exposures: Skilled nursing facility admission after PDPM implementation. Main Outcomes and Measures: Main outcomes were individual and nonindividual (concurrent and group) therapy minutes per day, hospitalization within 40 days of SNF admission, SNF length of stay longer than 40 days, and discharge activities of daily living score. Results: The study cohort included 201 084 postacute-care patients (mean [SD] age, 83.8 [8.3] years; 143 830 women [71.5%]; 185 854 White patients [92.4%]); 147 711 were admitted pre-PDPM, and 53 373 were admitted post-PDPM. A decrease in individual therapy (RD estimate: -15.9 minutes per day; 95% CI, -16.9 to -14.6) and an increase in nonindividual therapy (RD estimate: 3.6 minutes per day; 95% CI, 3.4 to 3.8) were observed. Total therapy use in the first week following admission was about 12 minutes per day (95% CI, -13.3 to -11.3) (approximately 13%) lower for residents admitted post-PDPM vs pre-PDPM. No consistent and statistically significant discontinuity in hospital readmission (0.31 percentage point increase; 95% CI, -1.46 to 2.09), SNF length of stay (2.7 percentage point decrease in likelihood of staying longer than 40 days; 95% CI, -4.83 to -0.54), or functional score at discharge (0.04 point increase in activities of daily living score; 95% CI, -0.19 to 0.26) was observed. Nonindividual therapy minutes were reduced to nearly zero in late March 2020, likely owing to COVID-19-related restrictions on communal activities in SNFs. Conclusions and Relevance: In this cross-sectional study of SNF admission after PDPM implementation, a reduction of total therapy minutes was observed following the implementation of PDPM, even though PDPM was designed to be budget neutral. No significant changes in postacute outcomes were observed. Further study is needed to understand whether the PDPM is associated with successful discharge outcomes.

RESUMEN

OBJECTIVE: To describe the frequency and timing of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) antibody detection in a convenience sample of skilled nursing facility (SNF) residents with and without confirmed SARS-CoV-2 infection. DESIGN: Retrospective analysis of SNF electronic health records. SETTING: Qualitative SARS-CoV-2 antibody test results were available from 81 SNFs in 16 states. PARTICIPANTS: Six hundred and sixty nine SNF residents who underwent both polymerase chain reaction (PCR) and antibody testing for SARS-CoV-2. MEASUREMENTS: Presence of SARS-CoV-2 antibodies following the first positive PCR test for confirmed cases, or first PCR test for non-cases. RESULTS: Among 397 residents with PCR-confirmed infection, antibodies were detected in 4 of 7 (57.1%) tested within 7-14 days of their first positive PCR test; in 44 of 47 (93.6%) tested within 15-30 days; in 182 of 219 (83.1%) tested within 31-60 days; and in 110 of 124 (88.7%) tested after 60 days. Among 272 PCR negative residents, antibodies were detected in 2 of 9 (22.2%) tested within 7-14 days of their first PCR test; in 41 of 81 (50.6%) tested within 15-30 days; in 65 of 148 (43.9%) tested within 31-60 days; and in 9 of 34 (26.5%) tested after 60 days. No significant differences in baseline resident characteristics or symptoms were observed between those with versus without antibodies. CONCLUSIONS: These findings suggest that vulnerable older adults can mount an antibody response to SARS-CoV-2, and that antibodies are most likely to be detected within 15-30 days of diagnosis. That antibodies were detected in a large proportion of residents with no confirmed SARS-CoV-2 infection highlights the complexity of identifying who is infected in real time. Frequent surveillance and diagnostic testing based on low thresholds of clinical suspicion for symptoms and/or exposure will remain critical to inform strategies designed to mitigate outbreaks in SNFs while community SARS-CoV-2 prevalence remains high.

RESUMEN

Importance: The coronavirus disease 2019 (COVID-19) pandemic has severely affected nursing homes. Vulnerable nursing home residents are at high risk for adverse outcomes, but improved understanding is needed to identify risk factors for mortality among nursing home residents. Objective: To identify risk factors for 30-day all-cause mortality among US nursing home residents with COVID-19. Design, Setting, and Participants: This cohort study was conducted at 351 US nursing homes among 5256 nursing home residents with COVID-19-related symptoms who had severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection confirmed by polymerase chain reaction testing between March 16 and September 15, 2020. Exposures: Resident-level characteristics, including age, sex, race/ethnicity, symptoms, chronic conditions, and physical and cognitive function. Main Outcomes and Measures: Death due to any cause within 30 days of the first positive SARS-CoV-2 test result. Results: The study included 5256 nursing home residents (3185 women [61%]; median age, 79 years [interquartile range, 69-88 years]; and 3741 White residents [71%], 909 Black residents [17%], and 586 individuals of other races/ethnicities [11%]) with COVID-19. Compared with residents aged 75 to 79 years, the odds of death were 1.46 (95% CI, 1.14-1.86) times higher for residents aged 80 to 84 years, 1.59 (95% CI, 1.25-2.03) times higher for residents aged 85 to 89 years, and 2.14 (95% CI, 1.70-2.69) times higher for residents aged 90 years or older. Women had lower risk for 30-day mortality than men (odds ratio [OR], 0.69 [95% CI, 0.60-0.80]). Two comorbidities were associated with mortality: diabetes (OR, 1.21 [95% CI, 1.05-1.40]) and chronic kidney disease (OR, 1.33 [95%, 1.11-1.61]). Fever (OR, 1.66 [95% CI, 1.41-1.96]), shortness of breath (OR, 2.52 [95% CI, 2.00-3.16]), tachycardia (OR, 1.31 [95% CI, 1.04-1.64]), and hypoxia (OR, 2.05 [95% CI, 1.68-2.50]) were also associated with increased risk of 30-day mortality. Compared with cognitively intact residents, the odds of death among residents with moderate cognitive impairment were 2.09 (95% CI, 1.68-2.59) times higher, and the odds of death among residents with severe cognitive impairment were 2.79 (95% CI, 2.14-3.66) times higher. Compared with residents with no or limited impairment in physical function, the odds of death among residents with moderate impairment were 1.49 (95% CI, 1.18-1.88) times higher, and the odds of death among residents with severe impairment were 1.64 (95% CI, 1.30-2.08) times higher. Conclusions and Relevance: In this cohort study of US nursing home residents with COVID-19, increased age, male sex, and impaired cognitive and physical function were independently associated with mortality. Understanding these risk factors can aid in the development of clinical prediction models of mortality in this population.

RESUMEN

BACKGROUND/OBJECTIVES: Infection screening tools classically define fever as 38.0°C (100.4°F). Frail older adults may not mount the same febrile response to systemic infection as younger or healthier individuals. We evaluate temperature trends among nursing home (NH) residents undergoing diagnostic SARS-CoV-2 testing and describe the diagnostic accuracy of temperature measurements for predicting test-confirmed SARS-CoV-2 infection. DESIGN: Retrospective cohort study evaluating diagnostic accuracy of pre-SARS-CoV-2 testing temperature changes. SETTING: Two separate NH cohorts tested diagnostically (e.g., for symptoms) for SARS-CoV-2. PARTICIPANTS Veterans residing in Veterans Affairs (VA) managed NHs and residents in a private national chain of community NHs. MEASUREMENTS: For both cohorts, we determined the sensitivity, specificity, and Youden's index with different temperature cutoffs for SARS-CoV-2 polymerase chain reaction results. RESULTS: The VA cohort consisted of 1,301 residents in 134 facilities from March 1, 2020, to May 14, 2020, with 25% confirmed for SARS-CoV-2. The community cohort included 3,368 residents spread across 282 facilities from February 18, 2020, to June 9, 2020, and 42% were confirmed for SARS-CoV-2. The VA cohort was younger, less White, and mostly male. A temperature testing threshold of 37.2°C has better sensitivity for SARS-CoV-2, 76% and 34% in the VA and community NH, respectively, versus 38.0°C with 43% and 12% sensitivity, respectively. CONCLUSION: A definition of 38.0°C for fever in NH screening tools should be lowered to improve predictive accuracy for SARS-CoV-2 infection. Stakeholders should carefully consider the impact of adopting lower testing thresholds on testing availability, cost, and burden on staff and residents. Temperatures alone have relatively low sensitivity/specificity, and we advocate any threshold be used as part of a screening tool, along with other signs and symptoms of infection.

RESUMEN

BACKGROUND: Worldwide, young transgender women (YTW) contend with exceptionally high risks of HIV infection. Cross-sectional studies have suggested that co-occurring epidemics or "syndemics" of psychosocial problems may accelerate HIV acquisition and transmission through elevated sexual risk behavior among transgender women. We aimed to examine how a syndemic of 7 psychosocial problems potentiates HIV sexual risk behavior among a multicity, longitudinal cohort of sexually active YTW in the United States. METHODS: Between 2012 and 2015, 233 YTW from Boston, MA, and Chicago, IL, completed behavioral surveys at baseline, 4, 8, and 12 months. We used generalized estimating equations to examine the prospective relationship of overlapping psychosocial problems and HIV sexual risk behavior (ie, condomless anal or vaginal sex) among YTW. RESULTS: The prevalence of 7 psychosocial syndemic problems was substantial at baseline and remained high at each time point: 6.4% reported polydrug use in the past 4 months (excluding stimulants); 7.7% reported heavy alcohol use in the past 4 months; 10% reported a history of childhood sexual abuse; 15.9% reported stimulant use in the past 4 months; 41.7% reported experiencing lifetime intimate partner violence; 42.1% reported clinically significant depressive symptoms; and 68.6% reported lifetime transgender-specific victimization. We identified a statistically significant positive "dose-response" relationship between the number of psychosocial syndemic problems and condomless anal or vaginal sex over time. CONCLUSIONS: The accumulation of "syndemic" psychosocial problems predicted HIV sexual risk behavior in a prospective cohort of YTW. Given the high prevalence of psychosocial problems and HIV sexual risk behavior, as well as having the highest HIV incidence among any risk group, the HIV prevention agenda requires a shift toward improved assessment of psychosocial comorbidities and stronger integration with gender-affirming and supportive mental health, violence recovery, and addiction treatment services for this population.

RESUMEN

Adolescents are disproportionately impacted by HIV in the United States. Optimal effects from antiretroviral therapy (ART) can be achieved through stringent adherence to a daily medication regimen; for adolescents, this may be interrupted due to complex barriers unique to this age group. We previously conducted formative qualitative interviews with HIV-infected adolescents to identify key barriers facing adolescents regarding ART adherence and potential strategies to address these barriers. These data were used to inform an ART adherence intervention designed to overcome difficulties unique to HIV-infected adolescents (e.g., internalized stigma and HIV-related shame, disclosure to sexual partners, social life, and extracurricular activities at school, etc.). The resulting intervention-"Positive Strategies To Enhance Problem-solving Skills (Positive STEPS)"-combines five individual counseling sessions with daily text message reminders. We conducted a pilot randomized controlled trial of the intervention against a standard of care control and report on the feasibility of procedures and participant acceptability of the intervention in terms of content, structure, and format. ART adherence was measured in both arms through Medication Event Monitoring System pill caps and self-report. Feasibility and acceptability of the Positive STEPS intervention was evidenced by 90% retention for the intervention sessions; 100% completion of the four-month assessment; and positive responses on postintervention evaluation forms (all intervention participants rated Positive STEPS as "acceptable" or "very acceptable") and brief exit interviews. At the 4-month assessment visit, the change in ART adherence among the intervention group [mean change score = 13%, standard deviation (SD) = 29.5] was significantly higher compared with the standard of care group (mean change score = -26%, SD = 26.0; Cohen's d effect size = 1.43, confidence interval = 0.17-2.49, p = 0.02). Future testing of the intervention in a fully powered randomized controlled trial to determine efficacy is warranted.

RESUMEN

BACKGROUND: HIV infection among youth in the United States is on the rise. A high level of antiretroviral therapy (ART) adherence is crucial to treatment success and can minimize the population burden of the disease. However, the overall rate of ART adherence among youth is generally suboptimal and no published efficacious interventions exist to address the specific needs of this population. This paper describes the design of a stepped-care, "adaptive" ART adherence intervention protocol for HIV-infected adolescents and young adults. METHODS: This is a randomized controlled trial (RCT) to establish the efficacy of "Positive STEPS," a behavioral and technology-based intervention to optimize ART adherence and viral suppression among HIV-infected youth, ages 16 to 29. Participants are equally randomized to 1) the Positive STEPS intervention, which begins with two-way daily text messaging as a reminder system to take their medications; participants progress to a more intensive in-person counseling intervention if text messaging is not sufficient to overcome barriers; or 2) or standard of care (SOC). At randomization, all participants receive standardized ART adherence education. During the 4 major study assessment visits (baseline, 4-, 8-, and 12-months), participants have their blood drawn to measure HIV viral load and complete a mix of computer-based self-administered and interviewer-administered behavioral and psychosocial measures. The primary outcomes are improvements in viral load and ART adherence measured via a medication-tracking device (i.e., Wisepill) and self-report. DISCUSSION: Behavioral interventions are greatly needed to improve ART adherence among HIV-infected adolescents and young adults and prevent onward transmission. If effective, the intervention tested here will be one of the first rigorously-designed efficacy trials to promote ART adherence in this population, using an approach that holds promise for being readily integrated into real-world clinical settings.

RESUMEN

BACKGROUND: In the United States, problematic stimulant use is a prevalent and difficult to treat problem among men who have sex with men (MSM), as well as a major driver of HIV transmission through the large number of sexual partners and concomitant condomless anal sex (CAS). Evidence-based behavioral studies that address problematic stimulant use in MSM at risk for HIV infection are also lacking. In this paper, we describe the design of a behavioral intervention trial to reduce sexual risk behavior and stimulant use in HIV-uninfected MSM. METHODS: This study, funded by the National Institute on Drug Abuse (NIDA), is a randomized controlled trial (RCT) testing an integrated HIV risk reduction and behavioral activation counseling intervention (IMPACT) for HIV-uninfected, stimulant using MSM in Boston, MA, and Miami, FL. Participants are randomized (2:2:1) to either (1) the IMPACT intervention; (2) a relaxation condition, an active therapy time- and intensity-matched control; or (3) a standard of care risk reduction counseling comparison. At enrollment, all participants receive an HIV test and pre- and post-test counseling. The primary outcome is the difference in the rate of change in the number of self-reported condomless anal sex acts without the protection of consistent Pre-Exposure Prophylaxis (PrEP) use, as well as reductions in stimulant use during the prior 4-months. Major assessments are conducted at baseline, 4-, 8-, and 12-month follow-up visits. DISCUSSION: Effective and sustainable behavioral interventions are sorely needed to reduce HIV acquisition in stimulant using MSM at risk for HIV infection. In this study, we will evaluate the evidence of efficacy of the IMPACT intervention to reduce HIV acquisition in HIV-uninfected, stimulant-using MSM. If found effective, the intervention tested here holds promise for being readily integrated into real-world clinical settings.

RESUMEN

Men who have sex with men (MSM) account for nearly 70% of new HIV diagnoses, with young black MSM at the highest risk for infection in the United States. Pre-exposure prophylaxis (PrEP) can decrease HIV acquisition in at-risk individuals by over 90%. However, therapeutic efficacy requires a daily pill, posing adherence challenges. Experimental modalities, including injectable PrEP given once every 2 months, may improve adherence among those most in need. To assess interest in and preference for injectable PrEP, an online survey was mounted on two popular MSM sexual networking apps. Differences by age, race, and other characteristics were examined using multinomial logistic regressions. Of 4638 respondents, 73% expressed interest in injectable PrEP and 47% indicated they would prefer an injection (compared to 17% who prefer a daily pill and 36% who were unsure). Within this sample, interest in and preference for injectable PrEP was highest among MSM at highest risk for HIV infection (i.e., younger age groups, racial/ethnic minorities, those with risker sexual behavior). As a result, if proven effective in clinical trials, injectable PrEP has the potential to reduce social disparities in HIV transmission among MSM.
