Inclusion of nonrandomized studies of interventions in systematic reviews of interventions: updated guidance from the Agency for Health Care Research and Quality Effective Health Care program.
A guidance workgroup comprised systematic review experts utilized an informal consensus generation method to develop guidelines to inform decisions regarding the inclusion of nonrandomized studies of interventions (NRSIs) in systematic reviews (SRs) of the effects of interventions. The study found that varying topics may require varying decisions regarding NRSI inclusion. The researchers identified key considerations to inform the decisions; from refinement of topics through to development of protocols. During the scoping and refinement of topics, considerations were associated with the clinical decisional dilemma, adequacy of randomized controlled trials (RCTs) to address the crucial questions, risk of bias in NRSIs, and the degree to which NRSIs are likely to complement RCTs. When NRSIs are included, during SR team formation, familiarity with topic-specific data sources and advanced analytic methods for NRSIs should be considered. During protocol development, the decision regarding NRSI inclusion or exclusion should be justified, and potential implications explained. When NRSIs are included, the protocol should describe the processes for synthesizing evidence from RCTs and NRSIs and determining the overall strength of evidence. CONCLUSION: We identified specific considerations for decisions regarding NRSI inclusion in SRs and highlight the importance of flexibility and transparency.
