After hip-or knee-replacement surgery, elderly patients have a 70% lower chance of dying within 3 months if they take an anticoagulant drug to prevent venous thrombosis. However, in a retrospective cohort study that included over 10 000 people in Quebec, Rahme and colleagues found that only 1 in 5 patients actually received thromboprophylaxis.
A related commentary by Fisher and Turpie points out the need for standard policies to eliminate noncompliance.

Adverse events in hospital
Preventable adverse events in hospital occur 3 times more often among patients with communication problems, find Bartlett and colleagues. They used a screening tool designed to detect these events and looked at nearly 2400 patient records from 20 hospitals in Quebec. Having a psychiatric disorder or being an emergency admission were the other risk factors they identified.
In a related commentary, Frankel says that simple mechanisms to enhance and assure comprehension by patients are available but need to be applied vigorously.
Medication-related visits to the emergency department
Of patients who visit the emergency department, 12% do so for a drug-related reason. Of these visits, 68% are potentially preventable. This was found by Zed and colleagues in their prospective observational study of over 1000 patients in Vancouver, British Columbia. The most common reasons for drug-related visits were adverse drug reactions, nonadherence or use of wrong or suboptimal drugs.

New hospitals dedicated to the treatment of obstetric fistula in Ethiopia continue to be built as a result of the rising incidence of the condition. But critics say educational measures aimed at preventing fistulas would likely be of more value (page 1527).
