Multicenter retrospective studies can provide a pragmatic approach to evaluating uncommon pediatric conditions and are less expensive than prospective research. A well-executed retrospective multicenter study, with rigorous study design, systematic data collection, and robust statistical analysis, can produce clinically important and generalizable findings A variety of observational designs can be employed, including cross-sectional, cohort, and case-control studies. Selection bias, ascertainment bias, and confounding are common issues in retrospective research. Key steps include development of a feasible study design, regular contact with site investigators, and detailed data collection and management strategies. Principal investigators must seek to ensure that case ascertainment and data collection are consistent across sites, using manual and/or automated data extraction methods. Operations manuals, training sessions, and regular meetings can be used to ensure data reliability. Ethical considerations include obtaining institutional review board approval and establishing data use agreements. A proactive statistical approach to handling missing data, using techniques like multiple imputation and sensitivity analyses, is necessary. Careful planning, effective collaboration, and embracing technological advancements will enhance the value and accuracy of retrospective multicenter studies. This article discusses important considerations in the performance of a retrospective multicenter study.
