Survey to determine the relative importance of clinical factors used to make empiric antibiotic decisions.

A cross-sectional survey study of inpatient prescribers in a university health system was performed to assess the importance they place on different clinical risk factors when making empiric antibiotic decisions. Our findings show that these clinical risk factors were weighted differently based on the clinical scenario and the type of prescriber.

Assessing targeted screening and low rates of HIV testing.

OBJECTIVES: We assessed rates of HIV testing based on targeting patients with identified risk factors at the Veterans Affairs Medical Center in Washington, DC (VAMC-DC), where written informed consent along with pretest and posttest counseling had, until recently, been required by federal law. METHODS: A cumulative retrospective review of the period 2000 through 2007 was conducted to assess the number of patients who were provided medical care at VAMC-DC, tested for HIV, and underwent confirmatory testing. Data on demographic characteristics and risks for HIV acquisition were also collected. RESULTS: At VAMC-DC, 3.8% to 4.9% (mean=4.25%) of patients in care without known HIV infection underwent HIV screening annually. On average, HIV was confirmed at a yearly rate of 3.4% among those tested. During the study period, HIV prevalence ranged from 2.1% to 2.5%. Among patients receiving HIV care, 41.5% disclosed no risk factors for HIV acquisition. CONCLUSIONS: Given that the HIV prevalence observed in this study was above 2% and that 41.5% of patients in care did not disclose any acquisition risks, targeted HIV screening has not been sufficient. HIV testing must be broadened and offered as part of routine medical care.
