An article in the February issue of Washingtonian magazine (2/1, Vaida), entitled "Minor Mistakes, Deadly Results," produced with Kaiser Health News, reports on causes and prevention methods for hospital malpractice. Citing federal estimates that in 2010, faulty medical care contributed to the deaths of 15,000 Medicare patients each month, it says the core reasons are that hospitals "are hierarchical organizations resistant to change, they haven't done enough to create environments in which patient safety is a priority, and they've been reluctant to share patient-safety data with the public." Examining the patient safety efforts of five Washington area hospitals, the author found them employing such strategies as using checklists, enforcing hand-washing rules, breaking down hierarchical communication barriers and moving to digital records. Checklist use can help prevent the estimated 40 "wrong-site" operations occur in the US each week, and Johns Hopkins cut ICU bloodstream infections by 90 percent by consistently using checklists.
