Current Challenges to the United States’ AIDS Drug Assistance Program and Possible Implications of the Affordable Care Act

AIDS Drug Assistance Programs, enacted through the Ryan White Comprehensive AIDS Resources Emergency Act of 1990, are the “payer of last resort” for prescription medications for lower income, uninsured, or underinsured people living with HIV/AIDS. ADAPs face declining funding from the federal government. State funding of ADAP is discretionary, but some states increased their contributions to meet the gap in funding. The demand for ADAP support is increasing as people living with HIV are living longer; the antiretroviral therapy (ART) guidelines have been changed to recommend initiation of treatment for all; the United States is increasing HIV testing goals; and the recession continues. In the setting of increased demand and limited funding, ADAPs are employing cost containment measures. Since 2010, emergency federal funds have bailed out ADAP, but these are not sustainable. In the coming years, providers and policy makers associated with HIV care will need to navigate the implementation of the Affordable Care Act (ACA). Lessons learned from the challenges associated with providing sustainable access to ART for vulnerable populations through ADAP should inform upcoming decisions about how to ensure delivery of ART during and after the implementation of the ACA.

The Continuum of HIV Care in Rural Communities in the United States and Canada: What Is Known and Future Research Directions

Abstract: The nature of the HIV epidemic in the United States and Canada has changed with a shift toward rural areas. Socioeconomic factors, geography, cultural context, and evolving epidemics of injection drug use are coalescing to move the epidemic into locations where populations are dispersed and health care resources are limited. Rural–urban differences along the care continuum demonstrate the implications of this sociogeographic shift. Greater attention is needed to build a more comprehensive understanding of the rural HIV epidemic in the United States and Canada, including research efforts, innovative approaches to care delivery, and greater community engagement in prevention and care.

Effects of recent Virginia AIDS Drug Assistance Program policy changes on diabetes and hyperlipidemia control in people living with HIV

Objectives: To describe the impacts of Virginia AIDS Drug Assistance Program’s elimination of diabetes and hyperlipidemia medication on disease outcomes in people living with HIV. Methods: Data were collected on two groups of people living with HIV who were prescribed medications for diabetes and/or hyperlipidemia; one group received medications from AIDS Drug Assistance Program (ADAP) and the other group received medications from another source. Data were collected for 13 months before and after the policy change. Diabetes, hyperlipidemia, and HIV control were compared using standard laboratory measures. Results: During the pre-policy-change time period, non-ADAP patients had better diabetes control than ADAP patients, but with multivariate analysis, ADAP status was no longer a statistically significant predictor. Otherwise, no significant differences between groups were identified. Discussion: ADAP patients had worse diabetes control compared to the non-ADAP group before the policy change. It is possible that this is due to the AIDS Drug Assistance Program population’s poor access to non-HIV primary care, including care for diabetes. It is reassuring that, even during a time of flux in AIDS Drug Assistance Program resources, the AIDS Drug Assistance Program patients’ co-morbid and HIV outcomes were not negatively impacted.

Hospital days attributable to immune reconstitution inflammatory syndrome in persons living with HIV before and after the 2012 DHHS HIV guidelines

Background Immune reconstitution inflammatory syndrome (IRIS) can manifest with initiation or reintroduction of antiretroviral therapy (ART) in persons living with HIV (PLWH). In 2012, updated United States treatment guidelines recommended initiation of ART for all PLWH regardless of CD4 count. The objectives of this study were to quantify hospital usage attributable to IRIS and assess the reasons for hospitalization in PLWH before and after the guideline update. Methods Subjects were PLWH between 18–89 years of age who were hospitalized between November 1, 2009 and July 31, 2014. Equivalent time periods before and after updated treatment guidelines were considered, and designated as Time Period 1 and Time Period 2, respectively. IRIS-attributable hospitalizations were identified by ICD9 codes and electronic medical record searches with subsequent review and confirmation. For hospitalizations that were not confirmed as being IRIS-attributable, primary discharge diagnoses were reviewed. Results A total of 278 PLWH were hospitalized 521 times throughout the study period. Time Period 1 had 9 PLWH with 12 IRIS-attributable hospitalizations while Time Period 2 had 6 PLWH with 9 IRIS-attributable hospitalizations. A larger proportion of IRIS-attributable hospital days was observed in Time Period 1 compared to Time Period 2 (7.5 vs 4.2%; p < 0.001). Median length of stay for IRIS-attributable hospitalizations was longer than for other diagnoses, particularly during Time Period 1 (12.0 vs 4.0; p = 0.05). The most common causes for hospitalizations in PLWH were non AIDS-defining infection, AIDS-defining malignancy, and gastrointestinal. PLWH who had HIV viral suppression (<200 copies/mL) accounted for 34 and 24% of hospitalizations in Time Periods 1 and 2 respectively. Conclusions Hospitalizations for PLWH continue at high rates and IRIS is a significant contributing factor. In our single-center study, there was a lower number of IRIS-attributable hospitalizations and IRIS-attributable hospital days in Time Period 2 compared with Time Period 1. The hospital burden of IRIS may decrease over time as more PLWH are started on ART earlier in the course of infection. This study highlights the continued importance of early diagnosis and linkage to care of those infected with HIV, so that morbidity and costs associated with IRIS continue to decline.

Hepatitis C Within a Single Health System: Progression Along the Cascade to Cure Is Higher for Those With Substance Misuse When Linked to a Clinic With Embedded Support Services

Abstract Background Hepatitis C is now curable for most individuals, and national goals for elimination have been established. Transmission persists, however, particularly in nonurban regions affected by the opioid epidemic. To reach goals of elimination, barriers to treatment must be identified. Methods In this open cohort of all individuals diagnosed with active hepatitis C from 2010 to 2016 at a large medical center, we identified patient and clinic characteristics associated with our primary outcome, sustained virologic response (SVR). We performed a subgroup analysis for those with documented substance misuse. Results SVR was achieved in 1544 (41%) of 3790 people with active hepatitis C. In a multivariable Poisson regression model, SVR was more likely in individuals diagnosed outpatient (incident rate ratio [IRR], 1.7; 95% confidence interval [CI], 1.5–2.0), living in close proximity to the medical center (IRR, 1.2; 95% CI, 1.1–1.3), with private insurance (IRR, 1.1; 95% CI, 1.0–1.3), and with cirrhosis (IRR, 1.4; 95% CI, 1.3–1.5). Achieving SVR was less likely in those qualifying as indigent (IRR, 0.8; 95% CI, 0.8–0.9) and those with substance misuse (IRR, 0.8; 95% CI, 0.7–0.9). In the subgroup analysis of those with substance misuse, SVR rates were higher in those linked to the infectious diseases clinic, which has embedded support services, than those linked to the gastroenterology clinic, which does not (IRR, 1.4; 95% CI, 1.1–1.9). Conclusions Social determinants of health including proximity to care and poverty impacted achievement of SVR. Those with substance misuse, a high-priority population for treatment of hepatitis C, had better outcomes when receiving care in a clinic with embedded support services.

National Survey of United States Human Immunodeficiency Virus Medical Providers’ Knowledge and Attitudes About the Affordable Care Act

Abstract Background The Affordable Care Act (ACA) affects United States’ healthcare by offering Medicaid expansion and tax subsidies to persons with low incomes, and its interaction with the current human immunodeficiency virus (HIV) healthcare delivery system is complex. The objective was to explore HIV medical providers’ knowledge and attitudes about the ACA. Methods HIV medical providers were emailed a weblink to a survey. Descriptive statistics, Mann-Whitney U tests, and binary logistic regression were performed. Results Of the 253 survey participants, the majority (61%) answered all 4 knowledge questions correctly. About 70% knew whether or not their state had decided to expand Medicaid. About 1 in 10 did not know if the ACA eliminated the Ryan White Program. When rating whether the ACA would improve their patients’ HIV outcomes from 1–5 with 5 as “strongly agree,” the providers’ mean responses varied by state Medicaid status: 3.78 (standard deviation [SD], 0.83) for Medicaid expansion compared with 3.37 (SD, 1.00) for Medicaid nonexpansion (P = .002). Adjusting for medical provider type, years of HIV practice, and sources of ACA information, correct ACA knowledge was associated with providing care in a Medicaid nonexpansion state (adjusted odds ratio [aOR], 2.07; 95% confidence interval [CI], 1.11–3.88), obtaining knowledge from case managers (aOR, 1.89; 95% CI, 1.03–3.48), and obtaining knowledge from newspapers/magazines (aOR, 1.94; 95% CI, .99–3.81). Conclusions Medical providers in Medicaid expansion states were more optimistic about the ACA’s likelihood to improve their patients’ HIV outcomes. There are gaps in HIV medical providers’ understanding of the ACA. Education could enhance systems-based practice.
