# Provider perceptions of indications for red blood cell transfusion

## TL;DR

This study explores which factors clinicians consider important when deciding to transfuse red blood cells, beyond just hemoglobin levels.

## Contribution

The study identifies and prioritizes factors influencing transfusion decisions among inpatient clinicians.

## Key findings

- Only 7 of 30 factors were rated as 'very important' by over 66% of clinicians, with 5 being hemoglobin-related.
- Most clinicians believe anemia can cause significant adverse consequences and that restrictive transfusion is standard and optimal care.
- Despite guidelines, there is no consensus on non-hemoglobin factors important for transfusion decisions.

## Abstract

Guidelines for red blood cell transfusion recommend incorporating patient factors and clinical context beyond hemoglobin (Hb) levels. However, limited data exist on which factors clinicians consider important. Understanding these decision‐making elements can clarify how guidelines are applied and inform future research. This study aimed to identify and prioritize factors that influence transfusion decisions among inpatient clinicians.

Inpatient clinicians who are high utilizers of transfusion were administered a survey and asked to rate the importance of 30 decision‐making factors using a 3‐point Likert scale (very, somewhat, not important). Additional questions addressed transfusion practices and anemia management using a 5‐point Likert scale (very much disagree to very much agree). Descriptive statistics were used to characterize study participants and survey responses, and regression models explored associations between responses and participant characteristics.

Of 95 eligible clinicians, 85 (89%) completed the survey. Only 7 of the 30 factors were rated as “very important” by more than 66% of respondents; 5 of these were Hb‐related. Importance assigned to other non‐Hb‐related factors varied. Most clinicians (85%) do believe that anemia can result in significant adverse consequences. Most clinicians further believe that restrictive transfusion is standard of care (88%) and optimal (68%), but also that transfusion decisions need to incorporate factors other than a patient's Hb level (84%) at the same time.

Despite guidelines suggestions, there is a lack of consensus on what clinical factors beyond Hb clinicians believe are important in making transfusion decisions.
