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).
