Blood transfusion practices and blood-banking services in a Kenyan hospital

Abstract

OBJECTIVES: To identify ways to improve the operation of blood-screening programs and to decrease the inappropriate use of blood by evaluating blood-transfusion practices and blood-banking services in a Kenyan hospital. DESIGN: Prospective cohort. SETTING: The study was conducted in a rural district hospital in western Kenya between September 1990 and July 1991. METHODS: We collected data on all transfusion requests (blood donation, grouping, HIV screening) and blood recipients (age, sex, diagnosis, and for a 3-month period on the pediatric, maternity, and female wards, admission hemoglobin and outcome). RESULTS: During the 11-month study period, 799 patients received 927 transfusions: 67% were children < 15 years of age, 27% were adult women and 6% were adult men. Transfusions were often delayed due to reliance on patient-recruited donors. Patients who received blood donated on or after the date of request waited longer for transfusion (median, 3 days) than patients who received blood that had been banked and screened before the request (median, 1 day). Patient-recruited donors had a higher HIV-seropositivity rate than volunteer donors (13.4 and 4.6%, respectively; chi 2 test, P < 0.001). Overall, 47% of pediatric transfusions were classified as inappropriate: 23% did not meet the criteria of having hemoglobin < 5.0 g/dl and clinical evidence of respiratory distress, and 27% were transfused 2 or more days after requested. Among adults, 68% received one unit of blood or less. CONCLUSIONS: Improved laboratory services, reduction of unnecessary transfusions, and increased recruitment of volunteer donors are critical for improving the appropriate and timely use of blood and reducing transfusion-associated HIV transmission.
