Background: Retained foreign bodies discovered after surgery are documented as Agency for Health Care Quality and Research Patient Safety Indicators. Our goal was to identify pediatric patient and procedure risk factors and outcomes associated with RFB based on AHRQ Definitions.
Methods: We performed a retrospective case-control study of children with RFB using the PHIS database. Patients were defined as having RFB based on the AHRQ PSI definition. Controls were matched in a 5:1 ratio on age, procedure date, and hospital. Our primary outcome was the presence of RFB. Secondary outcomes included hospital length of stay and mortality.
Results: Patients with RFB often underwent emergent procedures, experienced one or more chronic conditions, and required ICU admission or mechanical ventilation. Musculoskeletal procedures contribute the largest numbers of RFB (30.4%), but interventional radiology procedures had higher odds of having RFB (AOR 7.88, p < 0.0001). After multivariate adjustment, children with RFB required 4 more days of hospitalization (p < .001), but there was no difference in mortality (p = .579).
Conclusions: The implications of our study include identifying which administrative flags can be used to identify children at higher risks for RFB. Early identification of at-risk patients and prevention are key towards addressing the primary problem and corresponding sequela of RFB.
