Patterns of Prescribing Antiretroviral Therapy Upon Discharge to Psychiatry Inpatients With HIV/AIDS at a Large Urban...

HIV infection is more prevalent among people with severe mental illness (SMI) than in the general population. People with SMI may lack access to recommended antiretroviral therapy (ART), and inpatient psychiatric admissions may be opportunities to ensure that individuals receive recommended treatment.

To evaluate ART prescription patterns on an inpatient psychiatry service.

In this retrospective, observational study, patient and admission characteristics and ART prescriptions were obtained for 248 HIV-positive inpatients between 2006 and 2012. Receipt of any ART, any recommended ART regimen, and ART with potentially harmful adverse events and drug interactions were examined. General estimating equation models were used to evaluate prescription patterns in relation to patient and admission characteristics.

ART was prescribed at 39% of discharges and increased by 51% during the study. Prescription was more common in admissions with an AIDS diagnosis and age greater than 29 years and less common in admissions associated with a psychotic diagnosis and shorter inpatient stays. When ART was prescribed, regimens were consistent with guideline recommendations 91% of the time. Prescription of potentially harmful regimens was limited.

In an acute inpatient psychiatry setting in an urban HIV/AIDS epicenter, where psychotic disorders and brief and involuntary admissions were the norm, guideline-recommended ART regimens were prescribed at almost 60% of discharges by the end of the study. Future studies should explore interventions to increase ART for high-risk subpopulations with SMI, including younger individuals or those with brief inpatient psychiatry hospitalizations.
