Randomized Controlled Trial Clinical Trial
A randomized trial of povidone-iodine compared with iodine tincture for venipuncture site disinfection: effects on rates of blood culture contamination.
Contamination of blood cultures creates problems in their interpretation and unneeded resource utilization. Because skin flora comprise the major group of contaminant species, more effective skin disinfection at the venipuncture site could reduce contamination. ⋯ Iodine tincture is superior to povidone-iodine for venipuncture site antisepsis before blood culture sampling. Because of the high costs associated with contaminated blood cultures, hospitals should consider switching from povidone-iodine to iodine tincture. Reduction of the contamination rate may improve the quality of patient care and reduce hospital costs.

To describe the observed sequence of withdrawal of eight different forms of life-sustaining treatment and to determine whether aspects of those treatments determine the order of withdrawal. ⋯ The preference for withdrawing some forms of life-sustaining treatments more than others is associated with intrinsic characteristics of these treatments. Once the decision has been made to forgo life-sustaining treatment, the process remains complex and appears to target many different goals simultaneously.

Unplanned hospital readmission within 30 days of discharge is considered a "sentinel event" for poor quality. Patients at high risk for this adverse event could be targeted for interventions designed to reduce their risk of readmission. The purpose of this study was to identify patient characteristics and risk factors at discharge associated with unplanned readmission within 30 days of hospital discharge. ⋯ If validated, these factors may identify patients at high risk of readmission. They suggest that interventions, such as improved discharge education programs, may reduce unplanned readmission.

Most patients with acute bronchitis who seek medical care are treated with antibiotics, although the effectiveness of this intervention is uncertain. We performed a meta-analysis of randomized, controlled trials to estimate the effectiveness of antibiotics in the treatment of acute bronchitis. ⋯ This meta-analysis suggests a small benefit from the use of the antibiotics erythromycin, doxycycline, or trimethoprim/sulfamethoxazole in the treatment of acute bronchitis in otherwise healthy patients. As this small benefit must be weighed against the risk of side effects and the societal cost of increasing antibiotic resistance, we believe that the use of antibiotics is not justified in these patients.
