Sequential multiple assignment randomization trial designs for nursing research.

With mounting pressure to move toward precision health care and implementation science, nurse researchers are faced with the challenge of producing evidence that their interventions are applicable in real-world clinical settings. Pragmatic clinical trials are critically important to generate evidence that is relevant to clinical practice. Pragmatic designs closely replicate true-to-life settings thereby expediting research translation and improving health outcomes. The Sequential Multiple Assignment Randomized Trial (SMART) is a valuable a pragmatic trial design that is receiving greater attention in nursing. SMART designs can be used to provide relevant clinical evidence by comparative evaluation of two or more alternative interventions. The objectives of this article are to provide: (a) A description of the main considerations and key components of SMART designs, and (b) a summary of three different nursing studies using SMART designs. Information provided by pragmatic nursing trials using SMART designs, which more closely mirror clinical practice, will facilitate evidence-based clinical practice.
