Background:
Laboratory and other healthcare professionals participate in developing clinical practice guidelines through systematic review of the evidence. A significant challenge is the identification of areas for analytic focus when the evidence consists of several categories of interventions and outcomes that span both laboratory and clinical processes. The challenge increases when these interventions present as sets of combined interventions. A scoping review may provide a transparent and defensible analytic route forward for systematic reviews challenged in this manner.
Content:
A scoping review was carried out to characterize the evidence on rapid identification of bloodstream infections. Fifty-five studies previously identified by the supported systematic review were charted in duplicate. Charted records were analyzed using descriptive content analysis and evidence mapping with a 5-step process.
Summary:
The 5-step analysis culminated in the characterization of 9 different intervention chain configurations that will facilitate the comparison of complex intervention practices across studies. Furthermore, our evidence map indicates that the current evidence base is strongly centered on 3 specific clinical outcomes, and it links these outcomes to the most represented intervention chain configurations. The scoping review effort generated a route forward for the supported systematic review and meta-analysis.
