Physician’s Subjective Increase in Awareness towards Perioperative Anaemia, Patient’s Blood Resource, and Transfusion after the Implementation of Patient Blood Management: A Nationwide Multicentre Survey

Abstract

Introduction: Patient blood management (PBM) is a clinical and multidisciplinary, 3-pillar concept. The aim of this study was to detect the subjective increase in physician’s awareness towards perioperative anaemia, patient’s blood resource, and transfusion after the implementation of PBM in German hospitals. Material and Methods: A survey among 56 hospitals from the German PBM Network group was conducted from October 27 to December 19, 2020. An electronic questionnaire with 28 questions was sent to the local PBM coordinator for the distribution at the hospital level. For assessment of the physician’s subjective increase in awareness, numeric rating scales (0 [no increase] – 10 [maximum increase]) were used. Results: In total, 404 clinicians from 56 hospitals completed the survey. The mean (±standard deviation) time of an existing PBM program was 4.8 (±2.2) years. The physician’s subjective increase in awareness towards anaemia (8.2 [±2.0]), patient’s blood resource (7.6 [±2.5]), and transfusion (8.1 [±1.9]) was the highest in physicians from hospitals with ≥21 implemented PBM measures. In addition, a subjective increase in awareness towards anaemia (6.6 [±3.3]), patient’s blood resource (7.0 [±3.3]), and transfusion (6.6 [±3.4]) was the highest in physicians with daily PBM contact. Conclusion: Results suggest that physician’s awareness towards perioperative anaemia, patient’s blood resource, and transfusion has increased, depending on the hospital’s number of implemented PBM measures and physician’s PBM contact in everyday clinical practice.
