Status of hospital-based blood transfusion services in low-income and middle-income countries: a cross-sectional international survey

Abstract

Objectives: Blood transfusion is life-saving for patients experiencing acute blood loss and severe anaemia. In low-income and middle-income countries (LMICs), low blood donation rates and unavailability of whole blood and blood components (blood products) impairs timely blood transfusion. To fulfil patient-specific blood orders, a hospital blood transfusion service (HBTS) receives orders from a prescriber for blood transfusion, tests and prepares blood products for the patient. This study sought to describe the current state of LMIC HBTS.

Design: A cross-sectional survey explored LMIC HBTS access to blood products, testing methods, policies and structure. Surveys were administered in English, Spanish, French and Russian, followed by a mixed-methods analysis.

Setting: HBTS within LMICs.

Participants: From among 124 public and private facilities invited to participate, we received 71 (57%) responses. Of these responses, 50 HBTS from 27 LMICs performed on-site blood transfusions.

Results: Most LMIC HBTS perform blood collection to generate blood products for their patients (36/47, 77%); few relied exclusively on an external supply of blood products (11/47, 23%). The primary reason for blood transfusion was adult anaemia for non-malignant conditions (17/112, 15%). Testing methods varied by gross national income per capita. Blood transfusion delays to patients were common (17/30, 57%) attributed to inadequate blood inventories (13/29, 45%). Other barriers included lack of regular clinician education about transfusion (8/29, 28%) and sustainable financial models for the HBTS (4/29, 14%).

Conclusion: This survey describes the status of HBTS in diverse LMICs, illustrating that the availability of blood products remains a principal problem, requiring HBTS to generate its own facility's blood supply. Currently, blood shortages are not reported as a patient-specific adverse event making systematic tracking of delays in transfusion difficult. These findings highlight areas for further exploration related to the lack of available blood inventories for transfusions at HBTS in LMICs.
