Data Search
This systematic review was performed using a preplanned protocol. The results were reported in adherence to the guidelines of the PRISMA statement (Preferred Reporting Items for Systematic Reviews and Meta-analyses). An experienced librarian created a search strategy utilized to systematically find relevant publications. The search was conducted in February 2022. The question addressed in this meta-analysis was whether QI interventions are associated with a reduction in inappropriate or rarely appropriate echocardiography testing and whether the effect persisted over time. A systematic search was conducted using Ovid MEDLINE, EMBASE, Scopus, Web of Science, Google Scholar, and EBSCO CINAHL for relevant literature that reported an association between cardiac imaging, AUC, and QI. The search was not restricted to time or publication status (Figure 1).
