How to implement of patient blood management pillar 1: An Italian expert opinion based on a "bundles" approach

Evaluating patient blood management practices using PBM metrics in a tertiary care center

BACKGROUND

PBM metrics play a crucial role in assessing and monitoring the effectiveness of PBM programs in healthcare settings. The present study aimed to assess the indicators to achieve effective enforcement of PBM at a tertiary care referral hospital.

SUBJECTS AND METHOD

A prospective observational study was conducted on patients admitted for elective surgery at a tertiary care referral centre. PBM metrics were developed and assessed for various parameters, including documentation, patient evaluation, blood ordering schedule, and appropriateness. Experts in transfusion medicine and haematology checked content validity. Eleven different parameters were analysed, and a score was assigned based on the performance. The outcome was categorized as poor, satisfactory, or good.

RESULTS

The study included 612 patients meeting the inclusion criteria and recruited from Orthopaedics, General Surgery, OBG, Urology, and ENT departments. All departments completed pre-operative anaemia tests, with General Surgery and Orthopaedics conducting the most red cell transfusions. During the study, all of the blood units were used, and there was no waste. The C/T ratio was greater in the Departments of General Surgery, Urology, and Otorhinolaryngology. Pre-operative anaemia was found in 44.12% of patients, 44 patients had red cell transfusions, with 65% getting single-unit PRBC transfusions. All departments received a PBM score between 17-19, showing adequate PBM but with room for improvement.

CONCLUSION

The current study utilized Patient Blood Management (PBM) metrics to critically assess the existing practices and identify the key gaps and areas for improvement in a tertiary care centre.

A Potential Indicator for Assessing Patient Blood Management Standard Implementation

(1) Background: Patient blood management (PBM) program as a multidisciplinary practice and a standard of care for the anemic surgical patient has an increasingly important role in reducing transfusions and optimizing both clinical outcomes and costs. Documented success of PBM implementation is not sufficient for implementation of recommendations and correct use at hospital level. The primary objective of our study was to define a composite patient blood management process safety index-Safety Index in PBM (SIPBM)-that measures the impact of screening and treating anemic patients on the efficiency and effectiveness of the patient care process undergoing elective surgery. (2) Methods: We conducted a retrospective comparative study in a tertiary hospital by collecting data and analyzing the Safety Index in PBM (SIPBM) in patients undergoing major elective surgical procedures. (3) Results: The percentage of patients from the total of 354 patients (178 in 2019 and 176 in 2022) included in the study who benefited from preoperative iron treatment increased in 2022 compared to 2019 from 27.40% to 36.71%. The median value of the SIPBM was 1.00 in both periods analyzed, although there is a significant difference between the two periods (p < 0.005), in favor of 2022. (4) Conclusions: Measuring the effectiveness of PBM implementation and providing ongoing feedback through the Safety Index in PBM (SIPBM) increases the degree to which opportunities to improve the PBM process are identified. The study represents a first step for future actions and baselines to develop tools to measure the safety and impact of the patient blood management process in the surgical field.
