Hospitalization rates among persons with HIV who gained Medicaid or private insurance after the Affordable Care Act in 2014.
The purpose of this study was to investigate whether gaining inpatient healthcare coverage had an effect on hospitalization rates among persons with HIV following implementation of the Affordable Care Act in 2014. Hospitalization data from 2015 were obtained on adults receiving longitudinal care at HIV clinics; all patients were previously uninsured and supported by the Ryan White HIV/AIDS Program (RWHAP) in 2013. Findings showed that acquiring inpatient coverage was not associated with a change in hospitalization rates.

Increased HIV testing in people who use drugs hospitalized in the first wave of the COVID-19 pandemic.
During the COVID-19 pandemic, due to lapses in harm reduction services, several public health experts forecasted subsequent increases in diagnosis of HIV in PWUD. As many inpatient hospitals reworked patient flow during the COVID-19 surge, the investigators hypothesized that HIV testing in PWUD would decrease. To answer this question, they compiled a deidentified list of hospitalized patients with electronic medical record indicators of substance use-a positive urine toxicology screen, prescribed medications to treat opioid use disorder, a positive CIWA score, or a positive CAGE score-admitted between January, 2020 and August, 2020.

HIV care cascade before and after hospitalization: impact of a multidisciplinary inpatient team in the US South.
Hospitalization represents an opportunity to re-engage out-of-care individuals, improve HIV outcomes, and reduce health disparities. The authors reviewed electronic health records of HIV-positive individuals hospitalized at an urban, public hospital between September 2013 and December 2015. They found that hospitalized patients with HIV had low rates of engagement in care, retention in care, and virologic suppression, though all three outcomes improved after hospitalization. A multidisciplinary transitions team improved care engagement and virologic suppression in those who received the intervention.

U.S. Hospitalization rates and reasons stratified by age among persons with HIV 2014-15.
The objective of this study was to evaluate hospitalization rates and reasons stratified by age among persons with HIV in longitudinal HIV care. Results showed that hospitalization rates increased significantly with age for cardiovascular disease, endocrine, renal, pulmonary, and oncology. All-cause hospitalization rates increased with older age, especially among non-communicable diseases, while non-AIDS defining infection remained the leading cause for hospitalization.

Hospital days attributable to immune reconstitution inflammatory syndrome in persons living with HIV before and after the 2012 DHHS HIV guidelines.
The researchers’objectives were to quantify hospital usage attributable to Immune reconstitution inflammatory syndrome (IRIS) and assess the reasons for hospitalization in persons living with HIV (PLWH) before and after the guideline update. In their 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.

Hospital use by persons with HIV in the 21st century: a 5-state study.
The purpose of this study was to determine whether reductions in hospital utilization observed immediately after the availability of highly active antiretroviral therapy (between 1995 and 2000) have persisted into the 21st century. It found that the total number of hospitalizations by persons with HIV in the 5 study states fell by one third between 2000 and 2013 even though the number of persons living with HIV increased by >50%.

Alcohol-related diagnoses and all-cause hospitalization among HIV-infected and uninfected patients: a longitudinal analysis of United States veterans from 1997 to 2011.
From 1997 to 2011, 46,428 HIV-infected and 93,997 uninfected patients were followed for 1,497,536 person-years. Overall hospitalization rates decreased among HIV-infected and uninfected patients. However, cardiovascular and renal insufficiency admissions increased for all groups while gastrointestinal and liver, endocrine, neurologic, and non-AIDS cancer admissions increased among those with an alcohol-related diagnosis.

In four ACA expansion states, the percentage of uninsured hospitalizations for people with HIV declined, 2012-14.
This study examines the influence of the Affordable Care Act's optional state Medicaid expansion on insurance coverage and health outcomes for hospitalized patients with HIV. It found that the percentage of hospitalizations of uninsured people with HIV in the four expansion states fell from 13.7 percent to 5.5 percent in the study period, while the percentage in the two nonexpanding states increased from 14.5 percent to 15.7 percent.

Thirty-day postoperative mortality among individuals with HIV infection receiving antiretroviral therapy and procedure-matched, uninfected comparators.
The researchers explored the current relationship between perioperative mortality and indicators of immune function, anemia, and hypoalbuminemia among HIV-infected and uninfected individuals. Among HIV-infected patients receiving antiretroviral therapy, modern postoperative mortality rates are low and lower CD4 cell counts are associated with increased mortality, but characteristics other than HIV status, such as age and hypoalbuminemia, are also important determinants of outcome.

Disparities in hospitalizations among HIV positive individuals for native Hawaiians and Asians compared to whites in Hawaii.
This study investigated characteristics and disparities in hospitalizations among HIV positive individuals for Asian American subgroups and Native Hawaiians using data from all hospitalizations in Hawai‘i between December 2006 and December 2010. It concluded that disparities appear to exist in rates of hospitalizations among HIV positive individuals for Native Hawaiians and Asians, as well as in the demographic and, to some degree, the clinical characteristics of those hospitalized.
