Comparison of two methods to estimate adverse events in the IBEAS Study (Ibero-American study of adverse events): cross-sectional versus retrospective cohort design.

ABSTRACT:

Background

Adverse events (AEs) epidemiology is the first step to improve practice in the healthcare system. Usually, the preferred method used to estimate the magnitude of the problem is the retrospective cohort study design, with retrospective reviews of the medical records. However this data collection involves a sophisticated sampling plan, and a process of intensive review of sometimes very heavy and complex medical records. Cross-sectional survey is also a valid and feasible methodology to study AEs.

Objectives

The aim of this study is to compare AEs detection using two different methodologies: cross-sectional versus retrospective cohort design.

Setting

Secondary and tertiary hospitals in five countries: Argentina, Colombia, Costa Rica, Mexico and Peru.
