In 2002, an estimated 877,000 lives were lost worldwide through suicide. Some developed nations have implemented national suicide prevention plans. Although these plans generally propose multiple interventions, their effectiveness is rarely evaluated. ⋯ Physician education in depression recognition and treatment and restricting access to lethal methods reduce suicide rates. Other interventions need more evidence of efficacy. Ascertaining which components of suicide prevention programs are effective in reducing rates of suicide and suicide attempt is essential in order to optimize use of limited resources.

Randomized Controlled Trial Clinical Trial
Supplemental perioperative oxygen and the risk of surgical wound infection: a randomized controlled trial.
Supplemental perioperative oxygen has been variously reported to halve or double the risk of surgical wound infection. ⋯ Patients receiving supplemental inspired oxygen had a significant reduction in the risk of wound infection. Supplemental oxygen appears to be an effective intervention to reduce SSI in patients undergoing colon or rectal surgery. Trial Registration ClinicalTrials.gov Identifier: NCT00235456.
