Criteria used to define appropriate red blood cell transfusion in the perioperative setting: a scoping review.
Article in BMC surgery, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
introductionIntraoperative red blood cell (RBC) transfusion strategies vary depending on multiple factors. Several studies have documented significant variability in RBC transfusion practices during surgery. This scoping review aimed to identify and describe existing criteria or clinical decision-making tools used to evaluate intraoperative and immediate post-operative RBC transfusion appropriateness.
methodsA scoping review was conducted and reported according to Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines with extension for scoping reviews. A systematic search of MEDLINE and EMBASE was conducted. Relevant references were also explored. Studies reporting on the development, use, or validation of a clinical tool or set of criteria to adjudicate the appropriateness of intra- or post-operative RBC transfusions were eligible for inclusion.
resultsA total of 3,342 de-duplicated articles were identified. 135 underwent full text review, and 28 were included in the analysis. One tool was designed specifically for use during surgery. Adjudication of perioperative RBC transfusion appropriateness was determined using pre-existing published society guidelines in 61% of studies. 29% used a pre-defined set of criteria selected by the study team, and one study used RAND-UCLA to achieve consensus on appropriate transfusion criteria.
conclusionThis review identified several tools that were used to adjudicate the appropriateness of intraoperative and immediate postoperative RBC transfusions. Almost all studies adjudicated transfusion appropriateness based on guidelines intended for use outside of perioperative settings. Further research is required to develop RBC transfusion adjudication criteria that specifically integrate the unique factors that influence transfusion in the perioperative setting.
