Transfusion safety: Is there a difference between reported reactions in low-to-middle income and high-income countries?

BACKGROUND AND OBJECTIVES

Transfusion safety may be becoming dependent on the financial resources made available for transfusion structures and may vary between high-income countries (HIC) and low-to-middle-income countries (LMIC). To assess whether there is a difference in the reported TR between these two groups of countries, we examined TR reported in Tunis the capital of Tunisia, a LMIC, and compared their frequency with reported TR in HIC.

MATERIALS AND METHODS

Data of TR were collected from transfusion incident report (TIR) forms declared by healthcare facilities in Tunis between 2015 and 2019. They were analysed and compared to reported TR in France (ANSM) and UK (SHOT).

RESULTS

The incidence of TR was 70.6/100 000 blood components (BP) issued. A third of TR (36.8%) occurred at night. Febrile non-hemolytic transfusion reactions (43.7%) and allergic reactions (35%) were the most reported TR respectively 22.4/100 000 BP and 17.9/100 000 BP. The rate of ABO incompatibilities was 1.96/100 000 red blood cell units (RBC): they were all caused by human error. The rates of TRALI, TACO and bacterial contaminations were respectively 1.26/100 000 BP, 1.4/100 000 RBC and 0.7/100 000 BP.

CONCLUSION

While advanced technologies applied to transfusion have improved transfusion safety, this study shows that their impact has been relatively minor, as reported TR in LMIC are still comparable to those in HIC. ABO-incompatibilities are still higher in LMIC: this should be addressed by reinforcing the training of all healthcare personnel involved in transfusion medicine.
