Hospitalization is a missed opportunity for HIV screening, pre-exposure prophylaxis, and treatment.

BACKGROUND: Hospitalization is a "reachable moment" for people who inject drugs (PWID), but preventive care including HIV testing, prevention and treatment is rarely offered within inpatient settings. METHODS: We conducted a multisite, retrospective cohort study of patients with opioid use disorder with infectious complications of injection drug use hospitalized between 1/1/2018-12/31/2018. We evaluated HIV care continuum outcomes using descriptive statistics and hypothesis tests for intergroup differences. RESULTS: 322 patients were included. Of 300 patients without known HIV, only 2 had a documented discussion of PrEP, while only 1 was prescribed PrEP on discharge. Among the 22 people with HIV (PWH), only 13 (59%) had a viral load collected during admission of whom all were viremic and 10 (45%) were successfully linked to care post-discharge. Rates of readmission, Medicaid or uninsured status, and unstable housing were high in both groups. DISCUSSION: We observed poor provision of HIV testing, PrEP and other HIV services for hospitalized PWID across multiple U.S. medical centers. Future initiatives should focus on providing this group with comprehensive HIV testing and treatment services through a status neutral approach.

Use of nonstigmatizing language is associated with improved outcomes in hospitalized people who inject drugs.

BACKGROUND: Stigma surrounding opioid use disorder (OUD) is a barrier to treatment. The use of stigmatizing language may be evidence of negative views toward patients. OBJECTIVE: We aimed to identify associations between language and clinical outcomes in patients admitted for infectious complications of OUD. DESIGNS: We performed a retrospective medical record review. SETTINGS AND PARTICIPANTS: Four U.S. academic health systems. Participants were patients with OUD admitted for infectious complications of injection opioid use from January 1, 2018, to December 31, 2018, identified through international classification of diseases, 10th revision codes consistent with OUD and acute bacterial/fungal infection. MAIN OUTCOME AND MEASURES: Discharge summaries were reviewed for language, specifically: abuse, addiction, dependence, misuse, use disorder, intravenous drug use, and others. Binary outcomes including medication for OUD, planned discharge, naloxone provision, and an OUD treatment plan were evaluated using logistic regressions and admission duration was evaluated using Gamma regression. RESULTS: A total of 1285 records were reviewed and 328 met inclusion criteria. Of those, 191 (58%) were male, with a median age of 38 years. The most common term was "abuse" (219, 67%), whereas "use disorder" was recorded in 75 (23%) records. Having "use disorder" in the discharge summary was associated with increased odds of having a documented plan for ongoing OUD treatment (adjusted odds ratio [AOR]: 4.11, 95% confidence interval [CI]: 1.89-8.93) and having a documented plan for addiction-specific follow-up care (AOR: 2.31, 95% CI: 1.30-4.09). CONCLUSIONS: Stigmatizing language was common in this study of patients hospitalized for infectious complications of OUD. Best-practice language was uncommon, but when used was associated with increased odds of addiction treatment and specialty care referrals.

Undertreatment of opioid use disorder in patients hospitalized with injection drug use-associated infections.

OBJECTIVE: To evaluate the association between medication for opioid use disorder (MOUD) initiation and addiction consultation and outcomes for patients hospitalized with infectious complications of injecting opioids. METHOD: This was a retrospective cohort study performed at four academic medical centers in the United States. The participants were patients who had been hospitalized with infectious complications of injecting opioids in 2018. Three hundred and twenty-two patients were included and their individual patient records were manually reviewed to identify inpatient receipt of medication for opioid use disorder (MOUD), initiation of MOUD, and addiction consultation. The main outcomes of interest were premature discharge, MOUD on discharge, linkage to outpatient MOUD, one-year readmission and death. RESULTS: Three hundred and twenty-two patients were predominately male (59%), white (66%), and median age 38 years, with 36% unstably housed, and 30% uninsured. One hundred and forty-five (45%) patients received MOUD during hospitalization, including only 65 (28%) patients not on baseline MOUD. Discharge was premature for 64 (20%) patients. In the year following discharge, 27 (9%) patients were linked to MOUD, and 159 (50%) patients had at least one readmission. Being on MOUD during hospitalization was significantly associated with higher odds of planned discharge [odds ratio (OR) 3.87, P  < 0.0001], MOUD on discharge (OR 129.7, P  < 0.0001), and linkage to outpatient MOUD (OR 1.25, P  < 0.0001), however, was not associated with readmission. Study limitations were the retrospective nature of the study, so post-discharge data are likely underestimated. CONCLUSION: There was dramatic undertreatment with MOUD from inpatient admission to outpatient linkage, and high rates of premature discharge and readmission. Engagement in addiction care during hospitalization is a critical first step in improving the care continuum for individuals with opioid use disorder; however, additional interventions may be needed to impact long-term outcomes like readmission.

Assessing Racial Disparities in HCV Infection and Care Outcomes in a Southern Urban Population.

OBJECTIVES: This study assessed racial disparities in access to healthcare services, hepatitis C virus (HCV) exposure, and retention in a treatment cascade in two indigent populations in an urban center in the Southern US. PARTICIPANTS/METHODS: Opt-in HCV antibody screening was offered at two large homeless centers and three residential substance abuse treatment centers (SATCs) in New Orleans, LA. Five hundred ninety-four participants experiencing homelessness and 342 residents of SATCs were assessed for previous access/perceived barriers to healthcare services and high-risk behaviors associated with HCV exposure. Participants were then screened using rapid HCV antibody testing and tracked through a treatment cascade involving referral to a primary care provider (PCP), RNA confirmation, and specialist referral. RESULTS: In both the homeless and SATC populations, whites were more likely to report barriers to accessing healthcare and high-risk behaviors, especially prior intravenous drug use (IVDU). Interaction between age and race demonstrates a protective effect of white ethnicity at higher ages, at a level approaching statistical significance. Non-whites were equally likely to access follow-up care and treatment as whites. CONCLUSIONS: Despite many more risk factors reported by the white population, HCV antibody positivity was largely equal between the two racial groups. Known interactions between race and age in the African American population were demonstrated in these high-risk, urban populations. Whites were no more likely to achieve various levels of a treatment and care cascade. The results may demonstrate the impact of improved access to testing services and primary care, although access to treatment remains a significant barrier to eliminating racial disparities in HCV infection.

High level of HIV-1 drug resistance mutations in patients with unsuppressed viral loads in rural northern South Africa.

BACKGROUND: Combination antiretroviral therapy (cART) has significantly reduced HIV morbidity and mortality in both developed and developing countries. However, the sustainability of cART may be compromised by the emergence of viral drug resistance mutations (DRM) and the cellular persistence of proviruses carrying these DRM. This is potentially a more serious problem in resource limited settings. METHODS: DRM were evaluated in individuals with unsuppressed viral loads after first or multiple lines of cART at two sites in rural Limpopo, South Africa. Seventy-two patients with viral loads of >1000 copies/ml were recruited between March 2014 and December 2015. Complete protease (PR) and partial Reverse Transcriptase (RT) sequences were amplified from both plasma RNA and paired proviral DNA from 35 of these subjects. Amplicons were directly sequenced to determine subtype and DRM using the Stanford HIV Drug Resistance Interpretation algorithm. RESULTS: Among the 72 samples, 69 could be PCR amplified from RNA and 35 from both RNA and DNA. Sixty-five (94.2%) viruses were subtype C, while one was subtype B (1.4%), one recombinant K/C, one recombinant C/B and one unclassified. Fifty-eight (84%) sequences carried at least one DRM, while 11 (15.9%) displayed no DRM. DRM prevalence according to drug class was: NRTI 60.8% NNRTI 65.2%, and PI 5.8%. The most common DRMs were; M184V (51.7%), K103N (50%), V106M (20.6%), D67N (13.3%), K65R (12%). The frequency of the DRM tracked well with the frequency of use of medications to which the mutations were predicted to confer resistance. Interestingly, a significant number of subjects showed predicted resistance to the newer NNRTIs, etravirine (33%) and rilpivirine (42%), both of which are not yet available in this setting. The proportion of DRM in RNA and DNA were mostly similar with the exception of the thymidine analogue mutations (TAMs) D67N, K70R, K219QE; and K103N which were slightly more prevalent in DNA than RNA. Subjects who had received cART for at least 5 years were more likely to harbour >2 DRM (p < 0.05) compared to those treated for a shorter period. DRM were more prevalent in this rural setting compared to a neighbouring urban setting. CONCLUSION: We found a very high prevalence of NRTI and NNRTI DRM in patients from rural Limpopo settings with different durations of treatment. The prevalence was significantly higher than those reported in urban settings in South Africa. The dominance of NNRTI based mutations late in treatment supports the use of PI based regimens for second line treatment in this setting. The slight dominance of TAMs in DNA from infected PBMCs compared to plasma virus requires further studies that should include cART subjects with suppressed virus. Such studies will improve our understanding of the pattern of drug resistance and dynamics of viral persistence in these rural settings.

PPACA and Low-Income People Living with HIV: 2014 Qualified Health Plan Enrollment in a Medicaid Nonexpansion State.

People living with human immunodeficiency virus (HIV) or acquired immunodeficiency syndrome (AIDS) often are uninsured or underinsured, and they may benefit from the Patient Protection and Affordable Care Act (PL 111-148) and its improved access to medical care. Safety net programs, such as AIDS Drug Assistance Programs (ADAP) funded through the Ryan White HIV/AIDS Program, which serve low-income people living with HIV, are incorporating Patient Protection and Affordable Care Act Marketplace-qualified health plans (QHPs) and helping to fund patients' participation. This changing landscape differs from state to state, and one main element contributing to the differing situations is whether a state elected to expand Medicaid. This review examines QHP enrollment of ADAP clients in Virginia, a Medicaid nonexpansion state, and explores some issues that affect people living with HIV in other Medicaid nonexpansion states. Virginia is a leader in the shift of ADAP healthcare delivery from direct medication provision to purchasing QHPs. Virginia ADAP clients accounted for approximately 2% of ADAP clients nationally, but they represent 17% of ADAP clients enrolled in QHPs nationwide. Ensuring good HIV care of the ADAP population is important to each patient's personal longevity, the public health, and the efficient use of healthcare dollars. As healthcare delivery models shift, the effects on patients and health outcomes achieved should be monitored, particularly for chronic diseases such as HIV.
