    IntroductionFew data describe the specific reasons for inpatient hardware removal in the pediatric population. This study was designed to understand the conditions necessitating inpatient removal following fracture surgery. Cost data was analyzed to understand the financial implications of these procedures.MethodsThe Kids' Inpatient Database (KID) was evaluated for the year 2012. Patients undergoing open reduction internal fixation following upper and lower extremity fractures as well as those undergoing hardware removal due to hardware complications were identified using ICD-9 CM diagnosis and procedure codes. Univariable and multivariable logistic regression were used to determine predictors of surgical removal due to complications, controlling for patient demographics and comorbidities.ResultsThe most common indication for removal was infection (1141 patients; 32%), followed by mechanical dysfunction (923; 25.4%), and pain (472; 13%). Logistic regression analysis showed that femur fractures (OR = 8.27, 95% CI: 7.63-8.96) and tibia/fibula fractures (OR = 1.24, 95% CI: 1.17-1.35) were independent predictors of infection-related hardware removal (P < 0.001). Patients who underwent removal due to infection were more likely to have asthma (OR = 1.87, 95% CI: 1.62-2.07), smoke tobacco (OR = 1.12, 95% CI: 1.05-1.23), and suffer from developmental delays (OR = 1.32, 95% CI: 1.19-1.54) (P < 0.001). Average hospital charges and costs were $36,349 and $11,792 respectively.ConclusionWhile most commonly performed as an outpatient procedure, inpatient hardware removal occurs with relative frequency and is most often performed for infection, mechanical failure, or pain. Risk factors for infection-related removal were identified and provide a basis for further investigation.
