Correlates of Intimate Partner Violence, Including Psychological Partner Violence, in a Multisite U.S. Cohort of People in HIV Care.

We examined past-year intimate partner violence (IPV), including psychological violence without physical/sexual violence, and health outcomes among people with HIV (PWH) in care in a multi-site U.S. cohort. Between 2016 and 2022, PWH reported 12-month psychological, physical, and sexual IPV in a routine assessment. We used linear and logistic regression models adjusted for age, race/ethnicity, and site to examine relationships with health outcomes. Among 9748 PWH (median age 50 years, 81% cisgender male/16% cisgender female/1% transgender female; 44% non-Hispanic white/36% non-Hispanic Black/15% Hispanic), 9.3% (n = 905) reported any IPV in the past 12 months; half reported psychological IPV without physical/sexual IPV (n = 453). PWH reporting any type of IPV were on average younger than those who did not experience IPV. In adjusted models, any IPV was associated with increased likelihood of unstable housing, HIV viral load detection (HIV viral load ≥ 75 copies/mL), moderate-to-severe depressive symptoms, anxiety with panic symptoms, substance use (methamphetamines, cocaine/crack, illicit opioids, marijuana, heavy episodic/hazardous drinking), and concern about exposure to sexually transmitted infection. PWH reporting any IPV in the past 12 months had 4.2% lower adherence to antiretroviral therapy, 2.4 more HIV-related symptoms, a 1.9 point higher HIV stigma score, and a 9.5% lower quality of life score than those without IPV. We found similar associations among PWH reporting only psychological IPV, without physical/sexual IPV. IPV was common among PWH. Half reporting IPV reported only psychological IPV and had similarly poor outcomes as those reporting physical/sexual IPV, demonstrating the need to assess psychological as well as physical and sexual IPV.

RESUMEN: Examinamos la violencia de la pareja íntima (intimate partner violence, IPV) del año anterior, incluida la violencia psicológica sin violencia física y sexual, así como los resultados sanitarios entre las personas con VIH (people with HIV, PWH) que reciben atención en una cohorte multicéntrica de los Estados Unidos. Entre 2016 y 2022, las PWH informaron situaciones de IPV psicológica, física y sexual durante los 12 meses en una evaluación de rutina. Se utilizaron modelos de regresión lineal y logística ajustados por edad, raza/etnia y centro para examinar las relaciones con los resultados sanitarios. Entre 9748 PWH (mediana de edad de 50 años, 81% de hombres cisgénero/16% de mujeres cisgénero/1% de mujeres transgénero; 44% de blancos no hispanos/36% de negros no hispanos/15% de hispanos), el 9,3% (n = 905) informaron haber sufrido algún tipo de IPV en los últimos 12 meses; la mitad informó situaciones de IPV psicológica sin IPV física y sexual (n = 453). Las PWH que informaron de cualquier tipo de IPV fueron, en promedio, más jóvenes que las que no sufrieron IPV. En los modelos ajustados, cualquier IPV se asoció con una mayor probabilidad de vivienda inestable, detección de carga viral del VIH (carga viral del VIH ≥ 75 copias/ml), síntomas depresivos de moderados a graves, ansiedad con síntomas de pánico, consumo de sustancias (metanfetaminas, cocaína/crack, opioides ilícitos, marihuana, consumo excesivo episódico/peligroso de alcohol) y preocupación por la exposición a infecciones de transmisión sexual. Las PWH que informaron alguna situación de IPV en los últimos 12 meses tuvieron un 4,2% menos de cumplimiento de la terapia antirretrovírica, un 2,4% más de síntomas relacionados con el VIH, una puntuación de estigma del VIH 1,9 puntos más alta y una puntuación de calidad de vida un 9,5% más baja que las que no sufrieron IPV. Se encontraron asociaciones similares entre las PWH que informaron solo IPV psicológica, sin IPV física y sexual. La IPV fue común entre las PWH. La mitad de las personas que informaron IPV solo informaron IPV psicológica y tuvieron resultados igualmente deficientes que los que informaron IPV física y sexual, lo que demuestra la necesidad de evaluar la IPV psicológica, al igual que la IPV física y sexual.

Alcohol and drug use severity are independently associated with antiretroviral adherence in the current treatment era.

Substance use in people with HIV (PWH) negatively impacts antiretroviral therapy (ART) adherence. However, less is known about this in the current treatment era and the impact of specific substances or severity of substance use. We examined the associations of alcohol, marijuana, and illicit drug use (methamphetamine/crystal, cocaine/crack, illicit opioids/heroin) and their severity of use with adherence using multivariable linear regression in adult PWH in care between 2016 and 2020 at 8 sites across the US. PWH completed assessments of alcohol use severity (AUDIT-C), drug use severity (modified ASSIST), and ART adherence (visual analogue scale). Among 9400 PWH, 16% reported current hazardous alcohol use, 31% current marijuana use, and 15% current use of ≥1 illicit drugs. In multivariable analysis, current methamphetamine/crystal use, particularly common among men who had sex with men, was associated with 10.1% lower mean ART adherence (p < 0.001) and 2.6% lower adherence per 5-point higher severity of use (ASSIST score) (p < 0.001). Current and more severe use of alcohol, marijuana, and other illicit drugs were also associated with lower adherence in a dose-dependent manner. In the current HIV treatment era, individualized substance use treatment, especially for methamphetamine/crystal, and ART adherence should be prioritized.

Motivation and context of concurrent stimulant and opioid use among persons who use drugs in the rural United States: a multi-site qualitative inquiry.

BACKGROUND: In recent years, stimulant use has increased among persons who use opioids in the rural U.S., leading to high rates of overdose and death. We sought to understand motivations and contexts for stimulant use among persons who use opioids in a large, geographically diverse sample of persons who use drugs (PWUD) in the rural settings. METHODS: We conducted semi-structured individual interviews with PWUD at 8 U.S. sites spanning 10 states and 65 counties. Content areas included general substance use, injection drug use, changes in drug use, and harm reduction practices. We used an iterative open-coding process to comprehensively itemize and categorize content shared by participants related to concurrent use. RESULTS: We interviewed 349 PWUD (64% male, mean age 36). Of those discussing current use of stimulants in the context of opioid use (n = 137, 39%), the stimulant most used was methamphetamine (78%) followed by cocaine/crack (26%). Motivations for co-use included: 1) change in drug markets and cost considerations; 2) recreational goals, e.g., seeking stronger effects after heightened opioid tolerance; 3) practical goals, such as a desire to balance or alleviate the effects of the other drug, including the use of stimulants to avoid/reverse opioid overdose, and/or control symptoms of opioid withdrawal; and 4) functional goals, such as being simultaneously energized and pain-free in order to remain productive for employment. CONCLUSION: In a rural U.S. cohort of PWUD, use of both stimulants and opioids was highly prevalent. Reasons for dual use found in the rural context compared to urban studies included changes in drug availability, functional/productivity goals, and the use of methamphetamine to offset opioid overdose. Education efforts and harm reduction services and treatment, such as access to naloxone, fentanyl test strips, and accessible drug treatment for combined opioid and stimulant use, are urgently needed in the rural U.S. to reduce overdose and other adverse outcomes.

Vaporized nicotine use among patients in HIV care who smoke tobacco: perceived health effects and effectiveness as a smoking cessation tool.

Evidence suggests adverse health effects from vaporized nicotine (VN) use, such as electronic "e" cigarettes, and limited efficacy to aid tobacco cessation. People with HIV (PWH) smoke tobacco at higher rates than the general population, with greater morbidity, highlighting the necessity of effective tobacco cessation tools. PWH may be more vulnerable to adverse effects of VN. Using semi-structured 1:1 interviews, we examined health beliefs regarding VN, patterns of use, and perceived effectiveness for tobacco cessation among PWH in HIV care at three geographically diverse U.S. sites. PWH (n = 24) had limited understanding of VN product content or health effects, presuming VN less harmful than tobacco cigarettes (TC). VN failed to adequately replicate the psychoactive effects or desired ritual of smoking TC. Concurrent TC use, and continuous VN use throughout the day, was common. Satiety using VN was elusive, and consumption quantity was difficult to track. VN had limited desirability and durability as a TC cessation tool among the interviewed PWH.

Impact and correlates of sub-optimal social support among patients in HIV care.

Social support (SS) predicts health outcomes among patients living with HIV. We administered a brief, validated measure of SS, the Multifactoral Assessment of Perceived Social Support, within a patient-reported outcomes assessment of health domains in HIV care at 4 U.S. clinics in English and Spanish (n = 708). In univariate analysis, low SS was associated with poorer engagement in care, antiretroviral adherence, and health-related quality of life; current methamphetamine/crystal use, depression, anxiety, and HIV stigma (all p < 0.001); any use of either methamphetamines/crystal, illicit opioids, or cocaine/crack (p = 0.001), current marijuana use (p = 0.012), nicotine use (p = 0.005), and concern for sexually transmitted infection exposure (p = 0.001). High SS was associated with undetectable viral load (p = 0.031). Multivariate analyses found low SS independently associated with depression (risk ratio (RR) 3.72, 95% CI 2.93-4.72), lower adherence (RR 0.76, 95% CI 0.64-0.89), poor engagement in care (RR 2.05, 95% CI 1.44-2.96), and having more symptoms (RR 2.29, 95% CI 1.92-2.75). Medium SS was independently associated with depression (RR 2.59, 95% CI 2.00-3.36), poor engagement in care (RR 1.62, 95% CI 1.15-2.29) and having more symptoms (RR 1.75, 95% CI 1.44-2.13). SS assessment may help identify patients at risk for these outcomes.

Patient acceptability and usability of a self-administered electronic patient-reported outcome assessment in HIV care: relationship with health behaviors and outcomes.

We assessed acceptability/usability of tablet-based patient-reported outcome (PRO) assessments among patients in HIV care, and relationships with health outcomes using a modified Acceptability E-Scale (AES) within a self-administered PRO assessment. Using multivariable linear regression, we measured associations between patient characteristics and continuous combined AES score. Among 786 patients (median age=48; 91% male; 49% white; 17% Spanish-speaking) overall mean score was 26/30 points (SD: 4.4). Mean scores per dimension (max 5, 1=lowest acceptability, 5=highest): ease of use 4.7, understandability 4.7, time burden 4.3, overall satisfaction 4.3, helpfulness describing symptoms/behaviors 4.2, and enjoyability 3.8. Higher overall score was associated with race/ethnicity (+1.3 points/African-American patients (95%CI:0.3-2.3); +1.6 points/Latino patients (95%CI:0.9-2.3) compared to white patients). Patients completing PROs in Spanish scored +2.4 points on average (95%CI:1.6-3.3). Higher acceptability was associated with better quality of life (0.3 points (95%CI:0.2-0.5)) and adherence (0.4 points (95%CI:0.2-0.6)). Lower acceptability was associated with: higher depression symptoms (-0.9 points (95%CI:-1.4 to -0.4)); recent illicit opioid use (-2.0 points (95%CI:-3.9 to -0.2)); multiple recent sex partners (-0.8 points (95%CI:-1.5 to -0.1)). While patients endorsing depression symptoms, recent opioid use, condomless sex, or multiple sex partners found PROs less acceptable, overall, patients found the assessments highly acceptable and easy to use.

Correlates of psychological intimate partner violence with HIV care outcomes on patients in HIV care.

BACKGROUND: Among people living with HIV (PLWH), physical intimate partner violence (IPV) is associated with poor virologic, psychiatric, and behavioral outcomes. We examined non-physical, psychological intimate partner violence (psy-IPV) and HIV care outcomes using data from two U.S. consortia. METHODS: We conducted multivariable analyses with robust standard errors to compare patients indicating/not indicating psy-IPV. RESULTS: Among PLWH (n = 5950), 9.5% indicated psy-IPV; these individuals were younger (- 3; 95% CI [- 2,-4], p-value < 0.001), less likely to be on antiretroviral treatment (ART) (0.73 [0.55,0.97], p = 0.03), less adherent to ART (- 4.2 [- 5.9,-2.4], p < 0.001), had higher odds of detectable viral load (1.43 [1.15,1.78], p = 0.001) and depression (2.63 [2.18,3.18], p < 0.001), and greater use of methamphetamines/crystal [2.98 (2.30,3.87),p < 0.001], cocaine/crack [1.57 (1.24,1.99),p < 0.001], illicit opioids [1.56 (1.13,2.16),p = 0.007], and marijuana [1.40 (1.15,1.70), p < 0.001]. CONCLUSION: Psychological IPV, even in the absence of physical or sexual IPV, appears to be associated with HIV care outcomes and should be included in IPV measures integrated into routine HIV care.

Individual and poly-substance use and condomless sex among HIV-uninfected adults reporting heterosexual sex in a multi-site cohort.

BACKGROUND: We analyzed the association between substance use (SU) and condomless sex (CS) among HIV-negative adults reporting heterosexual sex in the Seek, Test, Treat, and Retain (STTR) consortium. We describe the impact of SU as well as person/partner and context-related factors on CS, identifying combinations of factors that indicate the highest likelihood of CS. METHODS: We analyzed data from four US-based STTR studies to examine the effect of SU on CS using two SU exposures: 1) recent SU (within 3 months) and 2) SU before/during sex. Behavioral data were collected via 1:1 or self-administered computerized interviews. Adjusted individual-study, multivariable relative risk regression was used to examine the relationship between CS and SU. We also examined interactions with type of sex and partner HIV status. Pooled effect estimates were calculated using traditional fixed-effects meta-analysis. We analyzed data for recent SU (n = 6781; 82% men, median age = 33 years) and SU before/during sex (n = 2915; 69% men, median age = 40 years). RESULTS: For both exposure classifications, any SU other than cannabis increased the likelihood of CS relative to non-SU (8-16%, p-values< 0.001). In the recent SU group, however, polysubstance use did not increase the likelihood of CS compared to single-substance use. Cannabis use did not increase the likelihood of CS, regardless of frequency of use. Type of sex was associated with CS; those reporting vaginal and anal sex had a higher likelihood of CS compared to vaginal sex only for both exposure classifications (18-21%, p < 0.001). Recent SU increased likelihood of CS among those reporting vaginal sex only (9-10%, p < 0.001); results were similar for those reporting vaginal and anal sex (5-8%, p < 0.01). SU before/during sex increased the likelihood of CS among those reporting vaginal sex only (20%; p < 0.001) and among those reporting vaginal and anal sex (7%; p = 0.002). Single- and poly-SU before/during sex increased the likelihood of CS for those with exclusively HIV-negative partners (7-8%, p ≤ 0.02), and for those reporting HIV-negative and HIV-status unknown partners (9-13%, p ≤ 0.03). CONCLUSION: Except for cannabis, any SU increased the likelihood of CS. CS was associated with having perceived HIV-negative partners and with having had both anal/vaginal sex.

Anemia risk factors among people living with HIV across the United States in the current treatment era: a clinical cohort study.

BACKGROUND: Anemia is common among people living with HIV infection (PLWH) and is associated with adverse health outcomes. Information on risk factors for anemia incidence in the current antiretroviral therapy (ART) era is lacking. METHODS: Within a prospective clinical cohort of adult PLWH receiving care at eight sites across the United States between 1/2010-3/2018, Cox proportional hazards regression analyses were conducted among a) PLWH free of anemia at baseline and b) PLWH free of severe anemia at baseline to determine associations between time-updated patient characteristics and development of anemia (hemoglobin < 10 g/dL), or severe anemia (hemoglobin < 7.5 g/dL). Linear mixed effects models were used to examine relationships between patient characteristics and hemoglobin levels during follow-up. Hemoglobin levels were ascertained using laboratory data from routine clinical care. Potential risk factors included: age, sex, race/ethnicity, body mass index, smoking status, hazardous alcohol use, illicit drug use, hepatitis C virus (HCV) coinfection, estimated glomerular filtration rate (eGFR), CD4 cell count, viral load, ART use and time in care at CNICS site. RESULTS: This retrospective cohort study included 15,126 PLWH. During a median follow-up of 6.6 (interquartile range [IQR] 4.3-7.6) years, 1086 participants developed anemia and 465 participants developed severe anemia. Factors that were associated with incident anemia included: older age, female sex, black race, HCV coinfection, lower CD4 cell counts, VL ≥400 copies/ml and lower eGFR. CONCLUSION: Because anemia is a treatable condition associated with increased morbidity and mortality among PLWH, hemoglobin levels should be monitored routinely, especially among PLWH who have one or more risk factors for anemia.

Antiretroviral pill count and clinical outcomes in treatment-naïve patients with HIV infection.

OBJECTIVES: Treatment guidelines recommend single-tablet regimens for patients with HIV infection starting antiretroviral therapy. These regimens might be as effective and cost less if taken as separate drugs. We assessed whether the one pill once a day combination of efavirenz, emtricitabine and tenofovir reduces the risk of disease progression compared with multiple-pill formulations of the same regimen. METHODS: We selected treatment-naïve patients starting one-, two- or three-pill formulations of this regimen in data from the Antiretroviral Therapy Cohort Collaboration. These patients were followed until an AIDS event or death or until they modified their regimen. We analysed these data using Cox regression models, then used our models to predict the potential consequences of exposing a future population to either a one-pill regimen or a three-pill regimen. RESULTS: Among 11 739 treatment-naïve patients starting the regimen, there were 386 AIDS events and 87 deaths. Follow-up often ended when patients switched to the same regimen with fewer pills. After the first month, two pills rather than one was associated with an increase in the risk of AIDS or death [hazard ratio (HR) 1.39; 95% confidence interval (CI) 1.01-1.91], but three pills rather than two did not appreciably add to that increase (HR 1.19; 95% CI 0.84-1.68). We estimate that 77 patients would need to be exposed to a one-pill regimen rather than a three-pill regimen for 1 year to avoid one additional AIDS event or death. CONCLUSIONS: This particular single-tablet regimen is associated with a modest decrease in the risk of AIDS or death relative to multiple-pill formulations.

Circumstances Surrounding High-risk Sexual Experiences Among Primary Care Patients Living With and Without HIV.

INTRODUCTION: Rates of sexually transmitted infection (STI) are rising in the USA, yet STI risk remains under-addressed by providers, even in HIV care, and with high-risk patients. We interviewed primary care patients living with and without HIV regarding circumstances surrounding sexual risk behavior to identify opportunities for providers to address and reduce STI risk. METHODS: We conducted semi-structured 1:1 interviews with patients living with and without HIV reporting ≥ 1 sex partner and varying STI exposure risk in the past 12 months from four geographically diverse US HIV and primary care clinics. We audio-recorded, transcribed, and coded interviews by circumstance type, using double-coding to ensure inter-coder reliability. We used Fisher's exact and T tests to determine associations with demographic/risk factors. RESULTS: Patients (n = 91) identified a mean of 3 of 11 circumstances. These included substance use (54%), desire for physical/emotional intimacy (48%), lack of HIV/STI status disclosure (44%), psychological drivers (i.e., coping, depression; 38%), personal dislike of condoms (22%), partner condom dislike/refusal (19%), receiving payment for sex (13%), and condom unavailability (9%). Higher proportions of those who were high STI-exposure risk patients, defined as those with ≥ 2 sex partners in the past 3 months reporting never or sometimes using condoms, reported disliking condoms (p = .006); higher proportions of the high-risk and moderate-risk (≥ 2 partners and condom use "most of the time") groups reported substance use as a circumstance (p = .04). CONCLUSION: Circumstances surrounding perceived STI exposure risk were diverse, often overlapping, and dependent on internal, environmental, and partner-related factors and inadequate communication. Meaningful care-based interventions regarding HIV/STI transmission behavior must address the diversity and interplay of these factors.

A Comparison of Adherence Timeframes Using Missed Dose Items and Their Associations with Viral Load in Routine Clinical Care: Is Longer Better?

Questions remain regarding optimal timeframes for asking about adherence in clinical care. We compared 4-, 7-, 14-, 30-, and 60-day timeframe missed dose items with viral load levels among 1099 patients on antiretroviral therapy in routine care. We conducted logistic and linear regression analyses examining associations between different timeframes and viral load using Bayesian model averaging (BMA). We conducted sensitivity analyses with subgroups at increased risk for suboptimal adherence (e.g. patients with depression, substance use). The 14-day timeframe had the largest mean difference in adherence levels among those with detectable and undetectable viral loads. BMA estimates suggested the 14-day timeframe was strongest overall and for most subgroups although findings differed somewhat for hazardous alcohol users and those with current depression. Adherence measured by all missed dose timeframes correlated with viral load. Adherence calculated from intermediate timeframes (e.g. 14-day) appeared best able to capture adherence behavior as measured by viral load.

Validity assessment of the PROMIS fatigue domain among people living with HIV.

PURPOSE: To evaluate psychometric characteristics and cross-sectional and longitudinal validity of the 7-item PROMIS® Fatigue Short Form and additional fatigue items among people living with HIV (PLWH) in a nationally distributed network of clinics collecting patient reported data at the time of routine clinical care. METHODS: Cross-sectional and longitudinal fatigue data were collected from September 2012 through April 2013 across clinics participating in the Centers for AIDS Research Network of Integrated Clinical Systems (CNICS). We analyzed data regarding psychometric characteristics including simulated computerized adaptive testing and differential item functioning, and regarding associations with clinical characteristics. RESULTS: We analyzed data from 1597 PLWH. Fatigue was common in this cohort. Scores from the PROMIS® Fatigue Short Form and from the item bank had acceptable psychometric characteristics and strong evidence for validity, but neither performed better than shorter instruments already integrated in CNICS. CONCLUSIONS: The PROMIS® Fatigue Item Bank is a valid approach to measuring fatigue in clinical care settings among PLWH, but in our analyses did not perform better than instruments associated with less respondent burden.

Provider perceptions of the value of same-day, electronic patient-reported measures for use in clinical HIV care.

Strong evidence suggests that patient-reported outcomes (PROs) aid in managing chronic conditions, reduce omissions in care, and improve patient-provider communication. However, provider acceptability of PROs and their use in clinical HIV care is not well known. We interviewed providers (n = 27) from four geographically diverse HIV and community care clinics in the US that have integrated PROs into routine HIV care, querying perceived value, challenges, and use of PRO data. Perceived benefits included the ability of PROs to identify less-observable behaviors and conditions, particularly suicidal ideation, depression, and substance use; usefulness in agenda setting prior to a visit; and reduction of social desirability bias in patient-provider communication. Challenges included initial flow integration issues and ease of interpretation of PRO feedback. Providers value same-day, electronic patient-reported measures for use in clinical HIV care with the condition that PROs are (1) tailored to be the most clinically relevant to their population; (2) well integrated into clinic flow; and (3) easy to interpret, highlighting chief patient concerns and changes over time.

Body mass index and early CD4 T-cell recovery among adults initiating antiretroviral therapy in North America, 1998-2010.

OBJECTIVES: Adipose tissue affects several aspects of the cellular immune system, but prior epidemiological studies have differed on whether a higher body mass index (BMI) promotes CD4 T-cell recovery on antiretroviral therapy (ART). The objective of this analysis was to assess the relationship between BMI at ART initiation and early changes in CD4 T-cell count. METHODS: We used the North American AIDS Cohort Collaboration on Research and Design (NA-ACCORD) data set to analyse the relationship between pre-treatment BMI and 12-month CD4 T-cell recovery among adults who started ART between 1998 and 2010 and maintained HIV-1 RNA levels < 400 copies/mL for at least 6 months. Multivariable regression models were adjusted for age, race, sex, baseline CD4 count and HIV RNA level, year of ART initiation, ART regimen and clinical site. RESULTS: A total of 8381 participants from 13 cohorts contributed data; 85% were male, 52% were nonwhite, 32% were overweight (BMI 25-29.9 kg/m(2) ) and 15% were obese (BMI > 30 kg/m(2) ). Pretreatment BMI was associated with 12-month CD4 T-cell change (P < 0.001), but the relationship was nonlinear (P < 0.001). Compared with a reference of 22 kg/m(2) , a BMI of 30 kg/m(2) was associated with a 36 cells/µL [95% confidence interval (CI) 14, 59 cells/µL] greater CD4 T-cell count recovery among women and a 19 cells/µL (95% CI 9, 30 cells/µL) greater recovery among men at 12 months. At a BMI > 30 kg/m(2) , the observed benefit was attenuated among men to a greater degree than among women, although this difference was not statistically significant. CONCLUSIONS: A BMI of approximately 30 kg/m(2) at ART initiation was associated with greater CD4 T-cell recovery at 12 months compared with higher or lower BMI values, suggesting that body composition may affect peripheral CD4 T-cell recovery.

Lessons learned from the design and implementation of myocardial infarction adjudication tailored for HIV clinical cohorts.

We developed, implemented, and evaluated a myocardial infarction (MI) adjudication protocol for cohort research of human immunodeficiency virus. Potential events were identified through the centralized Centers for AIDS Research Network of Integrated Clinical Systems data repository using MI diagnoses and/or cardiac enzyme laboratory results (1995-2012). Sites assembled de-identified packets, including physician notes and results from electrocardiograms, procedures, and laboratory tests. Information pertaining to the specific antiretroviral medications used was redacted for blinded review. Two experts reviewed each packet, and a third review was conducted if discrepancies occurred. Reviewers categorized probable/definite MIs as primary or secondary and identified secondary causes of MIs. The positive predictive value and sensitivity for each identification/ascertainment method were calculated. Of the 1,119 potential events that were adjudicated, 294 (26%) were definite/probable MIs. Almost as many secondary (48%) as primary (52%) MIs occurred, often as the result of sepsis or cocaine use. Of the patients with adjudicated definite/probable MIs, 78% had elevated troponin concentrations (positive predictive value = 57%, 95% confidence interval: 52, 62); however, only 44% had clinical diagnoses of MI (positive predictive value = 45%, 95% confidence interval: 39, 51). We found that central adjudication is crucial and that clinical diagnoses alone are insufficient for ascertainment of MI. Over half of the events ultimately determined to be MIs were not identified by clinical diagnoses. Adjudication protocols used in traditional cardiovascular disease cohorts facilitate cross-cohort comparisons but do not address issues such as identifying secondary MIs that may be common in persons with human immunodeficiency virus.

Barriers to retention in inpatient and residential drug treatment among persons who use opioids and/or injection drugs living in the rural U.S.

AIM: Barriers to retention in inpatient and residential care for persons who use drugs are understudied in the rural context. We sought to better understand barriers to retention in inpatient and residential drug treatment in a large, multi-site, geographically diverse sample of persons who use opioids and/or injection drugs in the rural U.S. METHODS: We conducted semi-structured individual interviews with persons currently using opioids and/or injection drugs in 9 U.S. states, including Illinois, Kentucky, Massachusetts, North Carolina, New Hampshire, Ohio, Oregon, Vermont, and Wisconsin. Content areas included substance use history and experiences with all modalities of drug treatment. We performed initial structural coding followed by an iterative "open-coding" process of itemizing and categorizing content within each code, and a multi-coder memoing process to summarize themes. We identified themes using three levels of the Social-Ecological Model (SEM): individual, interpersonal, and facility-level (organizational) barriers. RESULTS: Among 304 interviewed, over half (n = 166, 54 %) reported having experienced inpatient and residential treatment. Lack of treatment retention was driven by interrelated factors at all levels of the SEM. Person-level factors inhibiting retention included lack of readiness to stop using, which was particularly true for court-ordered treatment, and dislike of "freedom limitations". The sole interpersonal-level factor was the influence of other patients on re-initiation of drug use. Facility-level barriers included unaddressed withdrawal symptoms and lack of access to MOUD, staff relatability, inadequate staff training, and, particularly in residential treatment, lack of structure and supervision. Lack of preparation for coping with real-world triggers was seen as a barrier to engagement in ongoing treatment. CONCLUSION: Barriers to retention in inpatient and residential substance use treatment were present at three levels of the SEM. Interviews suggest much room for improvement in inpatient and residential drug treatment programs with respect to improving access to MOUD, tailoring content to better address social challenges in the rural context, and improving quality control measures with respect to staff and resident supervision.

Evaluation of the single-item self-rating adherence scale for use in routine clinical care of people living with HIV.

The self-rating scale item (SRSI) is a single-item self-report adherence measure that uses adjectives in a 5-point Likert scale, from "very poor" to "excellent," to describe medication adherence over the past 4 weeks. This study investigated the SRSI in 2,399 HIV-infected patients in routine care at two outpatient primary HIV clinics. Correlations between the SRSI and four commonly used adherence items ranged from 0.37 to 0.64. Correlations of adherence barriers, such as depression and substance use, were comparable across all adherence items. General estimating equations suggested the SRSI is as good as or better than other adherence items (p's <0.001 vs. <0.001-0.99) at predicting adherence-related clinical outcomes, such as HIV viral load and CD4(+) cell count. These results and the SRSI's low patient burden suggest its routine use could be helpful for assessing adherence in clinical care and should be more widespread, particularly where more complex instruments may be impractical.

Racial and ethnic disparities in COVID-19 disease incidence independent of comorbidities, among people with HIV in the US.

OBJECTIVES: To define the incidence of clinically-detected COVID-19 in people with HIV (PWH) in the US and evaluate how racial and ethnic disparities, comorbidities, and HIV-related factors contribute to risk of COVID-19. DESIGN: Observational study within the CFAR Network of Integrated Clinical Systems cohort in 7 cities during 2020. METHODS: We calculated cumulative incidence rates of COVID-19 diagnosis among PWH in routine care by key characteristics including race/ethnicity, current and lowest CD4 count, and geographic area. We evaluated risk factors for COVID-19 among PWH using relative risk regression models adjusted with disease risk scores. RESULTS: Among 16,056 PWH in care, of whom 44.5% were Black, 12.5% were Hispanic, with a median age of 52 years (IQR 40-59), 18% had a current CD4 count < 350, including 7% < 200; 95.5% were on antiretroviral therapy, and 85.6% were virologically suppressed. Overall in 2020, 649 PWH were diagnosed with COVID-19 for a rate of 4.94 cases per 100 person-years. The cumulative incidence of COVID-19 was 2.4-fold and 1.7-fold higher in Hispanic and Black PWH respectively, than non-Hispanic White PWH. In adjusted analyses, factors associated with COVID-19 included female sex, Hispanic or Black identity, lowest historical CD4 count <350 (proxy for CD4 nadir), current low CD4/CD8 ratio, diabetes, and obesity. CONCLUSIONS: Our results suggest that the presence of structural racial inequities above and beyond medical comorbidities increased the risk of COVID-19 among PWHPWH with immune exhaustion as evidenced by lowest historical CD4 or current low CD4:CD8 ratio had greater risk of COVID-19.

Measuring depression levels in HIV-infected patients as part of routine clinical care using the nine-item Patient Health Questionnaire (PHQ-9).

Little is known about the psychometric properties of depression instruments among persons infected with HIV. We analyzed data from a large sample of patients in usual care in two US cities (n=1467) using the nine-item Patient Health Questionnaire (PHQ-9) from the PRIME-MD. The PHQ-9 had curvilinear scaling properties and varying levels of measurement precision along the continuum of depression measured by the instrument. In our cohort, the scale showed a prominent floor effect and a distribution of scores across depression severity levels. Three items had differential item functioning (DIF) with respect to race (African-American vs. white); two had DIF with respect to sex; and one had DIF with respect to age. There was minimal individual-level DIF impact. Twenty percent of the difference in mean depression levels between African-Americans and whites was due to DIF. While standard scores for the PHQ-9 may be appropriate for use with individual HIV-infected patients in cross-sectional settings, these results suggest that investigations of depression across groups and within patients across time may require a more sophisticated analytic framework.
