Nonclinical factors affecting intraoperative red blood cell transfusion: a systematic review
Authors' conclusion
Our systematic review has synthesized the literature on nonclinical and behavioural factors impacting intraoperative transfusion decision-making, categorized using the TDF.
Study context
- Population
- Studies evaluating nonclinical factors affecting intraoperative red blood cell (RBC) transfusion18 studies
- Outcome
- Nonclinical and behavioural factors driving intraoperative RBC transfusion, by TDF domain
Methodological detailstheoretical domains framework (TDF) coding, two independent reviewers, Databases searched from inception until August 2021; quality assessed with Mixed Methods Appraisal Tool, Included: 9 retrospective cohort studies, 6 cross-sectional surveys, 3 before-and-after studies

Pooled result
As reported in the abstract
- Most reported TDF domains: social influences, behavioural regulation, environmental context/resources, beliefs about consequences
- Social influences: social effects of peers, patients and institutional culture on decision-making
- Environmental context/resources: case volume, geographic location, case start time
- Beliefs about consequences: variable beliefs about consequences of both intraoperative transfusion and anemia
- Behavioural regulation: provider- and institutional-level audits, educational sessions, increased surgeon/anesthesiologist communication as strategies to optimize decision-making
