To quantify the yield from stool testing in pediatric inpatients and to identify criteria to test stool more deliberately without sacrificing diagnostic sensitivity.
A retrospective review was performed of all stool cultures, ova and parasite examinations, and Clostridia difficile toxin assays performed on pediatric inpatients, aged 3 days to 18 years, at Thomas Jefferson University Hospital, Philadelphia, Pa, for 1 year.
Medical records were reviewed for positive cases, each with 2 controls matched for age and test type.
For this study, the term admission refers to the interval between the times each patient was admitted to and discharged from the hospital.
Some patients had multiple stool tests sent to the laboratory during a single admission ; some patients had more than 1 admission during the study period.
Statistical analysis was performed using X2 analysis and the Student 2-tailed t test with a commercially available statistical software package (Statworks, Cricket Software, Philadelphia).
Of 250 patient admissions to the hospital for which stool was cultured, 7 cultures (2.8%) were positive.
Of 63 patient admissions having ova and parasite testing, 1 (2%) had a positive result.
Clostridia difficile toxin assays were performed on 40 patient admissions to the hospital, and 7 (18%) had a positive result.
Only 18 (3.0%) of 598 of all test results reviewed were positive.
