Stepped wedge cluster randomized trials enable rigorous evaluations of health intervention programs in pragmatic settings. The current study aims to update neurosurgeon scientists on the design of stepped wedge randomized trials. An overview of recent methodological developments for stepped wedge designs is presented. An update on newer associated methodological tools is included to aid with future study designs. The stepped wedge trial design is defined. Indications for the design are reviewed in depth. Key considerations are discussed including mainstream methods of analysis and sample size determination. Stepped wedge designs can be attractive to study intervention programs aiming to improve the delivery of patient care, especially when examining a small number of heterogeneous clusters.
