Déshydratation et malnutrition : deux facteurs de risque de décès indépendants chez l’enfant sénégalais hospitalisé

Abstract

Inpatient mortality is an indicator of the quality of care. We analyzed the mortality of under 5-year-old hospitalized children in the pediatric ward of Aristide Le Dantec Hospital for updating our data 10 years after our first study. We analyzed the data of the children hospitalized between 1 January and 31 December 2012. For each child, we collected anthropometric measurements converted to a z-score related to World Health Organization growth data. Logistic regression-generating models built separately with different anthropometric parameters were used to assess the risk of mortality according to children's characteristics. Data from 393 children were included. The overall mortality rate was 10% (39/393). Using logistic regression, the risk factors associated with death were severe wasting (odds ratio [OR]=8.27; 95% confidence interval [95% CI]) [3.79-18], male gender (OR=2.98; 95% CI [1.25-7.1]), dehydration (OR=5.4; 95% CI [2.54-13.43]) in the model using the weight-for-height z-score; male gender (OR=2.5; 95% CI [1.11-5.63]), dehydration (OR=8.43; 95% CI [3.83-18.5]) in the model using the height-for-age z-score; male gender (OR=2.7; 95% CI [1.19-6.24]), dehydration (OR=7.5; 95% CI [3.39-16.76]), severe deficit in the weight-for-age z-score (OR=2.4; 95% CI [1.11-5.63]) in the model using the weight-for-age z-score; and male gender (OR=2.5; 95% CI [1.11-5.63]) and dehydration (OR=8.43; 94% CI [3.83-18.5]) in the last model with mid-upper arm circumference (MUAC). Dehydration and malnutrition were two independent risk factors of death. The protocols addressing dehydration and malnutrition management should be audited and performed systematically for each child's anthropometric measurements at admission.
