Wilson RM, Michel P, Olsen S, et al. BMJ (Clinical research ed.). 2012;344:e832.

This study conducted a retrospective chart review of more than 15,000 hospitalization records in 8 countries and found an adverse event rate range of 2.5% to 18.4% per country. Investigators estimated that more than 80% were preventable, suggesting a call to action for broader international efforts to promote patient safety.
