Objective
To evaluate the appropriateness of packed red blood cell (PRBC) transfusions across different departments of a tertiary care hospital.
Methods
This audit included 632 patients admitted to the major departments of Hayatabad Medical Complex, Peshawar, Pakistan, who received one or more PRBC transfusions from November 2023 till July 2024. Six categories were defined who had different characteristics and thresholds for PRBC transfusion according to the Association for the Advancement of Blood & Biotherapies Red Blood Cell Transfusion International Guidelines. The appropriateness of PRBC transfusions was evaluated by checking if the pre-transfusion hemoglobin (Hb) met the threshold as specified in the guidelines. The chi-square test was used to test the association between the appropriateness of PRBC transfusions and the gender, department, and category of the patient. The significance of the difference in the mean pre-transfusion Hb was determined using an independent samples t-test.
Results
The median age was 30 years (IQR: 23-48.75). The majority of the patients were female (n=430, 68%). Patients from the Department of Gynecology and Obstetrics (n=267, 42.2%) outnumbered those from other departments. The majority of PRBC transfusions were inappropriate (n=465, 73.6%). Most transfusions in female patients (83.3%), in the patients of the Department of Gynecology and Obstetrics (95.5%), and in patients in the general category (86.9%) were found inappropriate. In the case of inappropriate transfusion, the mean pre-transfusion Hb was significantly different among departments, with the highest (14.1 gm/dL) value documented in the Department of Gynecology and Obstetrics.
Conclusion
Female patients, patients in the Department of Gynecology and Obstetrics, and patients in the general category had the highest frequency of inappropriate PRBC transfusions.
