Purpose: To calculate hospitalization rates of gastroenteritis among c
hildren in Ontario and to determine the association of hospitalization
of gastroenteritis with sociodemographic indicators and the availabil
ity of hospital beds. Methods: Ontario admission rates were calculated
from hospital discharge data for fiscal year 1991/92. Small area vari
ations, correlations between sociodemographic indicators and admission
rates were studied. Results: The age- and sex-adjusted admission rate
in 1991/92 was 411.1/100,000 with a 14-fold variation in Ontario. The
availability of paediatric beds was the only significant factor assoc
iated with high admission rates, with an estimated relative risk of 6.
75 (95% confidence interval: 1.26, 36.09, p < 0.027).Conclusion: Since
most children with gastroenteritis can be successfully managed as out
patients, high admission rates may be an indication of unnecessary hos
pitalization.
