Aranaz-Andrés JM, Aibar-Remón C, Vitaller-Murillo J, et al. Incidence of adverse events related to health care in Spain: results of the Spanish National Study of Adverse Events. J Epidemiol Community Health (1978). 2008;62(12):1022-9. doi:10.1136/jech.2007.065227.
This retrospective cohort study analyzed inpatient cases associated with adverse events (AEs) and found that the most frequent events were related to medications, hospital infections, and technical problems during a procedure. The authors point out that their AE rates mirror those described in Canada and Australia but are higher than those reported in the highly regarded Harvard Medical Practice Study.
