Abstract
OBJECTIVE: To determine the proportion of potentially avoidable deaths in children under five in Colombia, by department and municipality of residence, during the period from 2000 through 2018. METHODS: A multi-group and longitudinal ecological study was conducted in 33 departments and 1 118 municipalities over a period of 19 years. The deaths were classified as probably unavoidable or avoidable; the latter were then identified as treatable, preventable, or mixed; and a proportion was calculated relative to the total. Finally, clusters were created by municipality and by department and depicted in coropleth maps. RESULTS: Between 2000 and 2018, Colombia reported 228 942 deaths of children under five, of which 91.4% were avoidable (68.2% treatable, 6.8% preventable, and 16.5% mixed) with no difference by sex. At the national level, the proportion of avoidability declined from 93.5% to 88.5% during this period. César was the department with the largest proportion of avoidable deaths (94.1%), compared with Santander, which had the smallest (89.0%). At the municipal level, all the deaths were potentially avoidable in 99 municipalities, whereas Palmar (Santander) had the least (33.3%). CONCLUSIONS: Nine out of 10 of the deaths that occurred in children under five in Colombia during 2000-2018 could have been avoided, mainly through early and better quality medical care. Sizable differences were observed between subnational territories.
