{Abstract}: BACKGROUND: A pilot randomized controlled trial (RCT) conducted in children (2-17 y) with perforated appendicitis demonstrated an 89% probability of reduced intra-abdominal abscess (IAA) rate with povidone-iodine (PVI) irrigation, compared with no irrigation (NI). We hypothesized that PVI also reduced 30-day hospital costs.
METHODS: We conducted a retrospective economic analysis of a pilot RCT. Hospital costs, inflated to 2019 U.S. dollars, were obtained for index admissions and 30-day emergency visits and readmissions. Cost differences between groups were assessed using frequentist and Bayesian generalized linear models.
RESULTS: We observed a 95% Bayesian probability that PVI reduced 30-day mean total hospital costs ($16,555 [PVI] versus $18,509 [NI]; Bayesian cost ratio: 0.90, 95% CrI, 0.78-1.03). The mean absolute difference per patient was $1,954 less with PVI (95% CI, -$4,288 to $379).
CONCLUSIONS: PVI likely reduced the IAA rate and 30-day hospital costs, suggesting the intervention is both clinically superior and cost saving.
