METHODS: Comparisons were made between patients seen during peak gastroenteritis months (December-May) before (fiscal year [FYs] 1994-1997) and after (FYs 1998 and 1999) guideline implementation. Data were extracted from hospital charts, clinical databases, and billing records.
RESULTS: Following implementation, mean yearly ED encounters for AGE decreased 22% and mean yearly admissions decreased 33%. The percentage of admitted children with minor illness decreased (p = 0.002). Mean length of stay decreased 21% for children with minor illness (p = 0.0001) and 5% for others. Hydration status was noted in only 15% of ED charts examined but increased to 63% in FY 1998 and 86% in FY 1999 (p < 0.001). The proportion of admitted patients who advanced to a regular diet by discharge increased from 4.9% (FY 1997) to 23% (FY 1998) and 76% (FY 1999; p < 0.0001). Total inpatient days/year decreased by 43%. Mean hospital costs did not change significantly.
CONCLUSIONS: Following implementation, fewer patients with AGE were seen in the ED and fewer were admitted to the hospital for care. Hospital stays were shorter, and children were more likely to resume their diets before discharge.
