Rotavirus-related hospitalizations are responsible for high seasonal peaks in all-cause pediatric hospitalizations
The Pediatric Infectious Disease Journal , Volume 31 - Issue 12
BACKGROUND: Seasonal rotavirus (RV) epidemics partly overlap with those of other common childhood infections, thereby generating enormous, but poorly quantified, pressure on hospital resources during winter and spring. We assessed RV contribution to seasonal excess in all-cause pediatric hospitalizations and RV hospitalization incidence rate in an observational study. METHODS: The study was conducted among pediatric wards in 3 general hospitals and 1 pediatric tertiary care center. Numbers of RV hospitalizations were determined from 5-year data on confirmed RV hospitalizations and adjusted for RV underreporting, assessed through active surveillance for acute gastroenteritis during the 2011 RV season. Incidence rate and RV contribution to all-cause hospitalizations were determined on hospital administrative data and population statistics. RESULTS: RV accounted for 6.2% (95% confidence interval: 5.3-7.1) of all-cause pediatric hospitalizations among general hospitals and 3.1% (95% confidence interval: 2.9-3.3) at the tertiary care center, adjusted for the proportion RV underreporting among gastroenteritis patients (33%) as observed during active surveillance. Among general hospitals, there was a 30% increase in all-cause hospitalizations during the active season of common childhood infections compared with summer months. RV contributed 31% to seasonal excess in all-cause pediatric hospitalizations, representing 12.9% of hospitalizations between January and May. RV hospitalizations incidence rate in the population was 510/100,000 child-years <5 years (95% confidence interval: 420-600). CONCLUSION: RV is one of the main causes of seasonal peaks in pediatric hospitalizations, and as such contributes significantly to periodic high bed capacity pressures and associated adverse effects. RV vaccination benefits in this respect should be considered in decision-making processes.
