Distribution and Utilization Pattern of Single Donor Platelet Units Obtained by Platelet Apheresis at Regional Blood Center, Peshawar: a One-Year Retrospective Review

Abstract

Objective: To determine the distribution and utilization pattern of single donor platelet units collected by platelet apheresis at the Regional Blood Center, Peshawar, during a one-year period.

Study Design: Retrospective descriptive study.

Place and Duration of Study: Regional Blood Center, Peshawar, Pakistan. From January-2025 to December-2025.

Methodology: All the electronic records of single donor platelet units collected through platelet apheresis during the above-mentioned study period was reviewed. Data of 193 records, which fulfilled the inclusion criteria was analyzed and the demographic record of the donors, recipient departments, primary diagnosis of recipients, and monthly distribution of platelet apheresis procedures were extracted. The primary outcome measure was the departmental distribution and utilization pattern of single donor platelet units while the secondary outcomes included the demographic characteristics of the donor and the monthly distribution of the procedures. Descriptive statistics were employed to present the study findings.

Results: The mean age of platelet donors was 29.97 ± 7.63 years. Out of the total of 193 units, the Medicine/Medical ICU department (46.63%) demonstrated the highest utilization of single donor platelet units followed by the oncology department (36.27 %). The monthly distribution of platelet apheresis procedures remained stable throughout the year, with a modest increase during the months of October and March. Acute lymphoblastic leukemia was the most frequent primary diagnosis among recipients (19.17%), followed by chemotherapy-induced thrombocytopenia (15.54%) and dengue-associated thrombocytopenia (14.00%).

Conclusion: The demand for SDP transfusion was greatest among medical and oncology departments, and remained relatively stable throughout the year.
