Emerging from the Shadows: Trends in HIV Ambulatory Care, Viral Load Testing, and Viral Suppression in a U.S. HIV Cohort, 2019-2022: Impact of COVID-19 Pandemic.

OBJECTIVES: Analyze the acute impact and the longer-term recovery of COVID-19 pandemic effects on clinical encounter types, HIV viral load (VL) testing and suppression (HIV VL<200 copies/mL). DESIGN: Longitudinal cohort study of participants seen during 2019-2022 at eight HIV Outpatient Study (HOPS) sites. METHODS: Generalized linear mixed models (GLMM) estimated monthly rates of all encounters, office and telemedicine visits, and HIV VL tests using 2010-2022 data. We examined factors associated with non-suppressed VL (VL ≥ 200 copies/mL) and not having ambulatory care visits during the pandemic using GLMM for logistic regression with 2017-2022 and 2019-2022 data, respectively. RESULTS: Of 2351 active participants, 76.0% were male, 57.6% aged ≥ 50 years, 40.7% non-Hispanic White, 38.2% non-Hispanic Black, 17.3% Hispanic/Latino, and 51.0% publicly insured. The monthly rates of in-person and telemedicine visits varied during 2020 through mid-year 2022. Multivariable logistic regression showed persons with no encounters were more likely to be male or have VL ≥ 200 copies/mL. For participants with ≥1 VL test, the prevalence rate of HIV VL ≥ 200 copies/mL during 2020 was close to the rates from 2014 to 2019. The change in probability of viral suppression was not associated with participant's age, sex, race/ethnicity or insurance type. CONCLUSION: In thent encounters declined over 2 years during the pandemic with variations in telemedicine and in-person events, with relative maintenance of viral suppression. Ongoing recovery from the impact of COVID-19 on ambulatory care will require continued efforts to improve retention and patient access to medical services.

A Heavy Burden: Preexisting Physical and Psychiatric Comorbidities and Differential Increases Among Male and Female Participants After Initiating Antiretroviral Therapy in the HIV Outpatient Study, 2008-2018.

Attention to non-AIDS comorbidities is increasingly important in the HIV care and management in the United States. We sought to assess comorbidities before and after antiretroviral therapy (ART) initiation among persons with HIV (PWH). Using the 2008-2018 HIV Outpatient Study (HOPS) data, we assessed changes in prevalence of physical and psychiatric comorbidities, by sex, among participants initiating ART. Cox proportional hazards models were fit to investigate factors associated with the first documented occurrence of key comorbidities, adjusting for demographics and other covariates, including insurance type, CD4+ cell count, ART regimen, and smoking status. Among 1,236 participants who initiated ART (median age 36 years, CD4 cell count 375 cells/mm3), 79% were male, 66% non-white, 44% publicly insured, 53% ever smoked, 33% had substance use history, and 22% had body mass index ≥30 kg/m2. Among females, the percentages with at least one condition were: at ART start, 72% had a physical and 42% a psychiatric comorbidity, and after a median of 6.1 years of follow-up, these were 87% and 63%, respectively. Among males, the percentages with at least one condition were: at ART start, 61% had a physical and 32% a psychiatric comorbidity, and after a median of 4.6 years of follow-up, these were 82% and 53%, respectively. In multivariable Cox proportional hazards analyses, increasing age and higher viral loads (VL) were associated with most physical comorbidities, and being a current/former smoker and higher VL were associated with all psychiatric comorbidities analyzed. HOPS participants already had a substantial burden of physical and psychiatric comorbidities at the time of ART initiation. With advancing age, PWH who initiate ART experience a clinically significant increase in the burden of chronic non-HIV comorbidities that warrants continued surveillance, prevention, and treatment.

Disparities in Treatment with Direct-Acting Hepatitis C Virus Antivirals Persist Among Adults Coinfected with HIV and Hepatitis C Virus in US Clinics, 2010-2018.

Human immunodeficiency virus (HIV) and hepatitis C virus (HCV) coinfection carries substantial risk for all-cause mortality and liver-related morbidity and mortality, yet many persons coinfected with HIV/HCV remain untreated for HCV. We explored demographic, clinical, and sociodemographic factors among participants in routine HIV care associated with prescription of direct-acting antivirals (DAAs). The HIV Outpatient Study (HOPS) is an ongoing longitudinal cohort study of persons with HIV in care at participating clinics since 1993. There are currently eight study sites in six US cities. We analyzed medical records data of HOPS participants diagnosed with HCV since June 2010. Sustained virological response (SVR) was documented with first undetectable HCV viral load (VL). We assessed factors associated with being prescribed DAAs by multi-variable logistic regression and described the cumulative rate of SVR. Among 306 eligible participants, 131 (43%) were prescribed DAA therapy. Factors associated with greater odds of being prescribed DAA were older age, private health insurance, higher CD4 cell count, being a person who injects drugs, and receiving care at publicly funded sites (p < 0.05). Of 127 (97%) participants with at least 1 follow-up HCV VL, 110 (87%) achieved SVR at 12 weeks. Of the total 131 participants, 123 (94%) eventually achieved SVR. Less than half of HIV/HCV coinfected patients in HOPS have been prescribed DAAs. Interventions are needed to address deficits in DAA prescription, including among patients with public or no health insurance, younger age, and lower CD4 cell count.

Hepatitis C Virus Testing Among Men With Human Immunodeficiency Virus Who Have Sex With Men: Temporal Trends and Racial/Ethnic Disparities.

BACKGROUND: National guidelines recommend that sexually active people with human immunodeficiency virus (PWH) who are men who have sex with men (MSM) be tested for hepatitis C virus (HCV) infection at least annually. Hepatitis C virus testing rates vary by race/ethnicity in the general population, but limited data are available for PWH. METHODS: We analyzed medical records data from MSM in the HIV Outpatient Study at 9 human immunodeficiency virus (HIV) clinics from January 1, 2011 through December 31, 2019. We excluded observation time after documented past or current HCV infection. We evaluated HCV antibody testing in each calendar year among HCV-seronegative MSM, and we assessed testing correlates by generalized estimating equation analyses. RESULTS: Of 1829 eligible MSM who were PWH, 1174 (64.2%) were non-Hispanic/Latino white (NHW), 402 (22.0%) non-Hispanic black (NHB), 187 (10.2%) Hispanic/Latino, and 66 (3.6%) of other race/ethnicity. Most were ≥40 years old (68.9%), privately insured (64.5%), with CD4 cell count/mm3 (CD4) ≥350 (77.0%), and with HIV viral load <200 copies/mL (76.9%). During 2011-2019, 1205 (65.9%) had ≥1 HCV antibody test and average annual HCV percentage tested was 30.3% (from 33.8% for NHB to 28.5% for NHW; P < .001). Multivariable factors positively associated (P < .05) with HCV testing included more recent HIV diagnosis, public insurance, lower CD4, prior chlamydia, gonorrhea, syphilis, or hepatitis B virus diagnoses, and elevated liver enzyme levels, but not race/ethnicity. CONCLUSIONS: Although we found no disparities by race/ethnicity in HCV testing, low overall HCV testing rates indicate suboptimal uptake of recommended HCV testing among MSM in HIV care.

Hepatitis C Update and Expanding the Role of Primary Care.

Primary care physicians (PCPs) are increasing their role in the fight against the Hepatitis C Virus (HCV). Approximately 3.5 million Americans currently live with chronic HCV with rising incidence among young persons, especially those affected by the opioid epidemic. Online guidelines and drug interaction checkers streamline treatment and increase accessibility for both patients and providers. Although treatment with new Direct Acting Antiviral agents ensure cure rates that routinely exceed 95%, as well as cause fewer adverse effects than previously available interferon-based regimens, some states still restrict access to HCV treatment, including by mandating which providers can prescribe and treat HCV. This special communication reviews HCV treatment resources, discusses data demonstrating similar cure rates between PCPs and specialists, and argues that capacity-building among PCPs will be necessary to control the HCV epidemic.

HIV and HCV screening among trauma patients.

The purpose of this study was to develop a hepatitis C virus (HCV) and HIV screening program for patients evaluated by the trauma service and link to care. Patients were offered screening for HCV antibody and HIV. Demographics were collected on gender, race, age, and history of intravenous drug use. A navigator connected patients to treatment. In total, 1160 trauma patients were screened for HCV and/or HIV. There were 162 (14%) patients with HCV antibodies. Patients who inject drugs comprised 39.5% (64) of the HCV antibody positive group. Forty-six (68.7%) patients received linkage to care services and 55 (34%) patients were actively engaged in treatment. There were 155 (10.5%) of all eligible patients screened for HIV. Twenty-one (13.5%) patients were living with HIV (PLWH) and there were two (1.3%) new HIV infections. All new PLWH were linked to care and a total of 14 (73.7%) PLWH were on antiretroviral therapy. This is the first HCV and HIV screening and linkage to care program of trauma surgery patients. In this interim program evaluation, we found high prevalence of HCV antibody and HIV prevalence and high linkage to care rates. Trauma service HCV and HIV screening is an opportunity to diagnose, link, and re-engage a vulnerable population.

HIV Pre-Exposure Prophylaxis and Women: Survey of the Knowledge, Attitudes, and Beliefs in an Urban Obstetrics/Gynecology Clinic.

Uptake of HIV pre-exposure prophylaxis (PrEP) is low among women at risk for HIV acquisition. Of 468,000 women, whom the United States Centers for Disease Control and Prevention estimates to be eligible for PrEP, only 10,000 unique women have begun therapy through the third quarter of 2015. These data suggest insufficient HIV prevention efforts. This study, conducted at the site of an urban academic medical center with an emergency department HIV prevalence rate of 4%, assesses the knowledge, attitudes, and beliefs of women toward PrEP. A self-administered survey was conducted among women at a family planning obstetrics/gynecology clinic at Temple University Hospital (Philadelphia, PA). Participants assessed their HIV acquisition risk and answered eight questions regarding knowledge, attitudes, and beliefs toward PrEP. Three hundred eighty-nine surveys met inclusion criteria. Sixty-five percent of women were black, and 73% were between 18 and 33 years of age. The median self-perceived risk score was 0 (interquartile range = 2) using a Likert scale. Thirty-three percent of women believed that PrEP could work, and 27% knew that such a regimen existed. Concerns existed toward cost (44%) and side effects (39%). Fifty-seven percent of women surveyed stated that they would take a medication to prevent HIV, and 64% felt comfortable discussing the subject with her doctor. Our data demonstrate a lack of PrEP knowledge, although willingness for uptake among women at risk for HIV acquisition, and a need for directed education and outreach.

Reducing False-Positive HIV Diagnosis in Niger: A Women's Issue.

The entry into both HIV care and secondary prevention is first through the knowledge of one's own HIV status. Testing for HIV remains challenging in countries where clinicians rely on rapid testing algorithms because the routine use of confirmatory Western blot technology is unavailable. In this case report, we describe the case of a pregnant woman in Niger, who was falsely labeled as HIV positive during prenatal visits. We also describe our clinical algorithm that was developed to facilitate retesting in patients who initially tested HIV positive or indeterminant with rapid diagnostic tests. Vigilance is necessary to ensure that appropriate identification and treatment of HIV is provided to reduce mother-to-child transmission of HIV, to appropriately allocate resources, and to avoid falsely labeling patients with HIV.

Assessing Correlations of Physicians' Practice Intensity and Certainty During Residency Training.

BACKGROUND: Variation in physicians' practice patterns contributes to unnecessary health care spending, yet the influences of modifiable determinants on practice patterns are not known. Identifying these mutable factors could reduce unnecessary testing and decrease variation in clinical practice. OBJECTIVE: To assess the importance of the residency program relative to physician personality traits in explaining variations in practice intensity (PI), the likelihood of ordering tests and treatments, and in the certainty of their intention to order. METHODS: We surveyed 690 interns and residents from 7 internal medicine residency programs, ranging from small community-based programs to large university residency programs. The surveys consisted of clinical vignettes designed to gauge respondents' preferences for aggressive clinical care, and questions assessing respondents' personality traits. The primary outcome was the participant-level mean response to 23 vignettes as a measure of PI. The secondary outcome was a certainty score (CS) constructed as the proportion of vignettes for which a respondent selected "definitely" versus "probably." RESULTS: A total of 325 interns and residents responded to the survey (47% response rate). Measures of personality traits, subjective norms, demographics, and residency program indicators collectively explained 27.3% of PI variation. Residency program identity was the largest contributor. No personality traits were significantly independently associated with higher PI. The same collection of factors explained 17.1% of CS variation. Here, personality traits were responsible for 63.6% of the explained variation. CONCLUSIONS: Residency program affiliations explained more of the variation in PI than demographic characteristics, personality traits, or subjective norms.
