The impact of formulary restriction on the relative consumption of carbapenems in intensive care units at an academic medical center.

Antipseudomonal carbapenems are an important target for antimicrobial stewardship programs. We evaluated the impact of formulary restriction and preauthorization on relative carbapenem use for medical and surgical intensive care units at a large, urban academic medical center using interrupted time-series analysis.

Association between meeting core elements for inpatient antimicrobial stewardship and antibiotic utilization.

We used multivariable analyses to assess whether meeting core elements was associated with antibiotic utilization. Compliance with 7 elements versus not doing so was associated with higher use of broad-spectrum agents for community-acquired infections [days of therapy per 1,000 patient days: 155 (39) vs 133 (29), P = .02] and anti-methicillin-resistant S.

Antimicrobial stewardship practices in Virginia.

The Society of Healthcare Epidemiology of America, the Centers for Disease Control and Prevention, and the President's Council of Advisors on Science and Technology recognize the need to combat antimicrobial resistance through the promotion of antimicrobial stewardship programs. Health care facilities in Virginia were surveyed using a 23-item survey focused on facility characteristics and antimicrobial stewardship strategies. Antimicrobial stewardship activities were highly variable and many are missing key personnel and resources.

Subtherapeutic linezolid concentrations in a patient with morbid obesity and methicillin-resistant Staphylococcus aureus pneumonia: case report and review of the literature.

Objective: To report a case of subtherapeutic linezolid concentrations in a patient with morbid obesity.

Case Summary: A 34-year-old male with morbid obesity (265 kg, body mass index 82 kg/m(2)) was admitted for severe sepsis due to respiratory failure requiring emergent intubation and treatment of community-acquired pneumonia. Admission tracheal aspirate culture revealed methicillin-resistant Staphylococcus aureus (MRSA) for which vancomycin was prescribed.

Dapsone-induced sulfone syndrome.

Objective: To report a patient with dapsone-induced sulfone syndrome.

Case Summary: A 42-year-old HIV-infected African American man developed fever, lymphadenopathy, exfoliative dermatitis, hepatitis, and methemoglobinemia 4 weeks after starting dapsone. Complete resolution of symptoms and laboratory abnormalities occurred with cessation of dapsone therapy.
