On usage of artificial intelligence for predicting mortality during and post-pregnancy: a systematic review of literature

Abstract

Background Care during pregnancy, childbirth and puerperium are fundamental to avoid pathologies for the mother and her baby. However, health issues can occur during this period, causing misfortunes, such as the death of the fetus or neonate. Predictive models of fetal and infant deaths are important technological tools that can help to reduce mortality indexes. The main goal of this work is to present a systematic review of literature focused on computational models to predict mortality, covering stillbirth, perinatal, neonatal, and infant deaths, highlighting their methodology and the description of the proposed computational models. Methods We conducted a systematic review of literature, limiting the search to the last 10 years of publications considering the five main scientific databases as source. Results From 671 works, 18 of them were selected as primary studies for further analysis. We found that most of works are focused on prediction of neonatal deaths, using machine learning models (more specifically Random Forest). The top five most common features used to train models are birth weight, gestational age, sex of the child, Apgar score and mother’s age. Having predictive models for preventing mortality during and post-pregnancy not only improve the mother’s quality of life, as well as it can be a powerful and low-cost tool to decrease mortality ratios. Conclusion Based on the results of this SRL, we can state that scientific efforts have been done in this area, but there are many open research opportunities to be developed by the community.

Machine learning models based on clinical indices and cardiotocographic features for discriminating asphyxia fetuses—Porto retrospective intrapartum study

“…An unbalanced dataset is a big challenge because failure to solve this problem can lead to classifiers being biased. Recently, da Silva Rocha et al ( 18 ) reviewed the literature on computer models for mortality prediction, covering stillbirth, perinatal, neonatal, and infant deaths, and found that only 50% of studies addressed the crucial problem of the unbalanced dataset.…”
