BackgroundAcute diarrhea is a common health problem in children, especially those under five years of age (U5). The mortality rate due to acute diarrhea among U5 children accounted for 11% in Lao PDR in 2016. No study has been done to investigate the etiologic pathogens of acute diarrhea and the risk factors associated with dehydration status among U5 children hospitalized with acute diarrhea in this region.ObjectivesThe study aimed to evaluate the clinical characteristics, etiological agents and associated factors of dehydration status of acute diarrhea among hospitalized U5 children in Savannakhet Province, Lao PDR.MethodsThis retrospective study reviewed paper-based medical records with available stool examination results of 33 U5 children hospitalized with acute diarrhea in Savannakhet Provincial Hospital, Lao PDR between Jan. 2018 and Dec. 2019. Descriptive statistics were used to describe clinical characteristics and etiologic agents of acute diarrhea of the children. Nonparametric test, Pearson's Chi-square test and Fisher exact test were used to determine the risk factors associated with level of dehydration of the participants.ResultsVomiting was the most common symptom (66.6%), followed by fever (60.6%). Dehydration was found in 48.4% of subjects. Rotavirus was the most common identified pathogen with a prevalence of 55.5%. Bacterial enteric infection was identified in 15.1% of patients. There is a significantly higher prevalence of dehydration among children with acute diarrhea caused by rotavirus compared to those with negative rotavirus testing (70.0% vs. 12.5%, p = 0.02).ConclusionsRotavirus was the most prevalent pathogen of acute diarrhea among U5 children. Pediatric patients with acute diarrhea caused by rotavirus had a higher prevalence of dehydration compared to those with negative rotavirus testing.
