Importance: Whether people infected with human immunodeficiency virus (HIV) are at an increased risk of acute myocardial infarction (AMI) compared with uninfected people is not clear. Without demographically and behaviorally similar uninfected comparators and without uniformly measured clinical data on risk factors and fatal and nonfatal AMI events, any potential association between HIV status and AMI may be confounded.Objective: To investigate whether HIV is associated with an increased risk of AMI after adjustment for all standard Framingham risk factors among a large cohort of HIV-positive and demographically and behaviorally similar (ie, similar prevalence of smoking, alcohol, and cocaine use) uninfected veterans in care.

BackgroundSkin and soft tissue infections (SSTIs) are a leading cause for hospitalizations in the United States. Few studies have addressed the appropriateness of antibiotic therapy in the management of SSTIs without complicating factors. We aimed to determine the appropriateness of antibiotic treatment duration for hospitalized adult patients with uncomplicated SSTIs.MethodsThis was a retrospective analysis performed at two academic medical centers in Pittsburgh, Pennsylvania on patients aged 18 years and older with primary ICD-9 code for SSTIs admitted August 1st, 2014–March 31st, 2015. The primary outcome was the appropriateness of antibiotic treatment duration for uncomplicated SSTIs. Secondary objectives included the appropriateness of antibiotic agent spectrum, duration of inpatient length of stay (LOS), utilization of blood cultures and advanced imaging modalities, and re-hospitalization for SSTI within 30 days of discharge from the index admission.ResultsA total of 163 episodes were included in the cohort. The mean duration of total antibiotic therapy was 12.6 days. Appropriate duration was defined as receipt of total antibiotic duration of less than 10 days and occurred in 20.2% of patients. Twenty eight percent of patients received antibiotics for greater than 14 days. Seventy three (44.8%) patients received greater than 24 h of inappropriate extended spectrum gram-negative coverage; 65 (39.9%) received anaerobic coverage.ConclusionsIn the majority of patients, treatment duration was excessive. Inappropriate broad spectrum antibiotic selection was utilized with regularity for SSTIs without complicating factors. The management of uncomplicated SSTIs represents a significant opportunity for antimicrobial stewardship.

Despite three decades of dramatic treatment breakthroughs in antiretroviral regimens, clinical outcomes for people living with HIV vary greatly. The HIV treatment cascade models the stages of care that people living with HIV go through toward the goal of viral suppression and demonstrates that <30% of those living with HIV/AIDS in the United States have met this goal. Although some research has focused on the ways that patient characteristics and patient-provider relationships contribute to clinical adherence and treatment success, few studies to date have examined the ways that contextual factors of care and the healthcare environment contribute to patient outcomes. Here, we present qualitative findings from a mixed-methods study to describe contextual and healthcare environment factors in a Ryan White Part C clinic that are associated with patients' abilities to achieve viral suppression. We propose a modification of Andersen's Behavioral Model of Health Services Utilization, and its more recent adaptation developed by Ulett et al., to describe the ways that clinic, system, and provider factors merge to create a system of care in which more than 86% of the patient population is virally suppressed.
