ABSTRACT
INTRODUCTION:
Information on transfusion-associated outcomes is limited in sub-Saharan Africa. We sought to characterize predictors of mortality in transfused patients with acute care surgical conditions in Malawi.METHODS:
We performed a retrospective propensity-matched analysis of patients with acute care surgical conditions at Kamuzu Central Hospital in Malawi from 2013 to 2021. We compared outcomes between patients who did and did not receive transfusions.RESULTS:
A total of 7395 patients were included. Transfused patients (n = 1086) were older (median 43 y with interquartile range 30-59, versus 39 y [interquartile range 27-53] in the nontransfused group, P < 0.01), had a higher proportion of females (41% versus 27%, P < 0.01), presented earlier to the hospital (median 2.9 versus 3.7 d, P = 0.02), and with lower hemoglobin levels (27% versus 1% < 7 g/dL, P < 0.01). They had a lower rate of surgical intervention (48% versus 59%, P < 0.01) but a higher rate of complications (62% versus 33%, P < 0.01). Crude in-hospital mortality was 25.5% for the transfused group and 12.8% for the nontransfused group (P < 0.01). After propensity matching, transfused patients had three times the odds of mortality compared to nontransfused patients (odds ratio 3.3, 95% confidence interval 2.3, 4.8).CONCLUSIONS:
In this propensity-matched study, transfused surgical patients were more likely to experience in-hospital mortality. These results suggest that the transfusion requirement reflects critical illness and warrants further investigation in this low-resource setting.Palavras-chave
