In Mozambique, the probability of dying in the first month after hospital discharge is high, particularly for babies under three months of age, according to a study led by the Barcelona Institute of Global Health (ISGlobal). The study also shows that an algorithm based on a series of simple clinical parameters can identify those children at higher risk of dying and that would therefore benefit from a proactive follow-up after their discharge. The implementation of these models could contribute to reducing child mortality in low-income countries.

In the last 25 years, the reduction in mortality of children under five years of age has been remarkable but insufficient (50 percent instead of the 75 percent target set by the millennium goals). In , children are at increased risk of dying following hospitalisation, regardless of their illness, with an estimated risk ranging between three and 13 percent in the month following discharge. The challenge, therefore, is to identify those children at higher risk in order to follow them up closely after discharge, and thereby avoid a considerable number of pediatric deaths.

The performed a analysing data from more than 20,000 pediatric hospital admissions over almost 20 years in the district hospital of Manhiça, a semi-rural area in Southern Mozambique where almost half of the population is under 15 years of age. The researchers determined mortality during the first, second and third month after hospital discharge, and looked for indicators that could identify children at of dying.

"This is the largest study performed to date to evaluate mortality three months following in a rural area of a low-income country," explains Lola Madrid, ISGlobal researcher and first author of the study.

The results show that the average mortality after discharge is high (3.6 percent), with half of deaths occurring within the first 30 days. The risk is highest in babies under three months of age and decreases progressively with age. The study also identifies a series of clinical parameters (malnutrition, diarrhea, clinical pneumonia, etc.) that identify those children at highest mortality risk. Using all or some of these variables, the team used a series of predictive models capable of identifying up to 80 percent of children at risk of dying after discharge.

The children thus identified could benefit from close follow-up during the first 30 days by community health workers, or receive preventive antimicrobial therapies. "If these simple models, based on easy-to-obtain parameters like those used in our study, are validated in other contexts, they could represent a to save neonatal and infant lives in countries with a high burden of ," concludes Quique Bassat, ICREA researcher and study coordinator.
