This study investigated the survival of children referred from primary care in Malawi and found that severe hypoglycemia and hypoxemia were associated with increased mortality. Pre-referral glucose treatment and improved management of hypoglycemia could reduce the high case fatality ratio in children with severe hypoglycemia. The morbidity and mortality burden of severe hypoxemia was high, and ways to improve hypoxemia identification and management are needed.
Objective To investigate survival in children referred from primary care in Malawi, with a focus on hypoglycaemia and hypoxaemia progression. Methods The study involved a prospective cohort of children aged 12 years or under referred from primary health-care facilities in Mchinji district, Malawi in 2019 and 2020. Peripheral blood oxygen saturation (SpO(2)) and blood glucose were measured at recruitment and on arrival at a subsequent health-care facility (i.e. four hospitals and 14 primary health-care facilities). Children were followed up 2 weeks after discharge or their last clinical visit. The primary study outcome was the case fatality ratio at 2 weeks. Associations between SpO(2) and blood glucose levels and death were evaluated using Cox proportional hazards models and the treatment effect of hospitalization was assessed using propensity score matching. Findings Of 826 children recruited, 784 (94.9%) completed follow-up. At presentation, hypoxaemia was moderate (SpO(2): 90-93%) in 13.1% (108/826) and severe (SpO(2): < 90%) in 8.6% (71/826) and hypoglycaemia was moderate (blood glucose: 2.5-4.0 mmol/L) in 9.0% (74/826) and severe (blood glucose: < 2.5 mmol/L) in 2.3% (19/826). The case fatality ratio was 3.7% (29/784) overall but 26.3% (5/19) in severely hypoglycaemic children and 12.7% (9/71) in severely hypoxaemic children. Neither moderate hypoglycaemia nor moderate hypoxaemia was associated with mortality. Conclusion Presumptive pre-referral glucose treatment and better management of hypoglycaemia could reduce the high case fatality ratio observed in children with severe hypoglycaemia. The morbidity and mortality burden of severe hypoxaemia was high; ways of improving hypoxaemia identification and management are needed.
