Background

People with serious mental illness (SMI) are at elevated risk of HIV infection, but do not receive HIV tests regularly. Inpatient psychiatric admissions provide opportunities for HIV testing.

Objective

This study retrospectively examined the impact of three sequential interventions designed to increase HIV testing on an acute inpatient psychiatry service: (1) advocacy by an administrative champion, (2) an on-site HIV counselor, and (3) a clinician championing HIV testing.

Method

Demographic and HIV testing data were extracted from hospital data systems for 11,360 admissions of HIV-negative patients to an inpatient psychiatry service between 2006 and 2012. Relationships among interventions, length of stay, patient demographics, and receipt of an HIV test were examined using general estimating equation methods.

Results

In the year prior to the intervention, 7.2% of psychiatric inpatients received HIV tests. After 1 year of administrative advocacy, 11.2% received tests. Following the HIV counseling intervention, 25.1% of patients were tested. After the counseling intervention ended, continued administrative and clinical advocacy was associated with further increases in testing. In the final year studied, 30.3% of patients received HIV tests. Patients with shorter inpatient stays and those of Black or Asian race/ethnicity were less likely to be tested. Further, 1.6% of HIV tests were positive.

Conclusion

Three interventions of varying intensity were associated with a 5-fold increase in HIV testing on an acute inpatient psychiatry service. Nonetheless, 70% of inpatients were not tested. Continued efforts are needed to increase HIV testing in inpatient psychiatric settings.

Background

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.

Objective

To evaluate ART prescription patterns on an inpatient psychiatry service.

Methods

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.

Results

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.

Conclusion and relevance

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.

Proteomics is the large scale study of protein structure and function from biological systems through protein identification and quantification. Shotgun proteomics or bottom-up proteomics is the prevailing strategy, in which proteins are hydrolyzed into peptides that are analyzed by mass spectrometry. Proteomics studies can be applied to diverse studies ranging from simple protein identification to studies of proteoforms, protein-protein interactions, protein structural alterations, absolute and relative protein quantification, post-translational modifications, and protein stability. To enable this range of different experiments, there are diverse strategies for proteome analysis. The nuances of how proteomic workflows differ may be challenging to understand for new practitioners. Here, we provide a comprehensive overview of different proteomics methods to aid the novice and experienced researcher. We cover from biochemistry basics and protein extraction to biological interpretation and orthogonal validation. We expect this work to serve as a basic resource for new practitioners in the field of shotgun or bottom-up proteomics.
