Risk factors for 90-day readmission and prolonged length of stay after hip surgery in children with cerebral palsy

Objective: Spastic hip dysplasia is a common complication of cerebral palsy in children, and surgical intervention is usually warranted. While current literature has primarily analyzed single institution outcomes, this study utilized a national database to describe readmission rates and factors correlated with readmission for children with cerebral palsy undergoing hip surgery in order to treat this population more effectively.Methods: This study queried the Nationwide Readmissions Database (2014-2018) for pediatric patients with cerebral palsy who underwent hip surgery. Patient demographics, pre-operative comorbidities, length of stay (LOS), treatment complications, and readmission data were collected for each patient and analyzed with inferential statistics.Results: Of the 1225 patients included, the average age was 9.3 +/- 3.8 years and 42.8% were female. Approxi-mately 26.3% patients had a prolonged LOS (>= 5 days) and 14.2% patients required readmission within 90-days of surgery. Medical complications, cardiac arrhythmias, and iron deficiency anemia were all significantly associated with elongated LOS as well as 90-day readmission. Patients with Medicaid were more frequently associated with an inpatient medical complication and the overall complication rate was 5.5%.Conclusions: While current literature has analyzed common risk factors and complications associated with hip surgery in the pediatric cerebral palsy patient, this study identifies a national readmission rate (14.2%) as well as preoperative comorbidities associated with readmission within 90-days and/or elongated LOS. Notably, com-plications are more frequently associated with patients using Medicaid. These results further exemplify the importance of equitable access to care and thorough selection of pediatric cerebral palsy patients appropriate for hip surgery.

Automated summary

Spastic hip dysplasia is a common complication of cerebral palsy in children, and surgical intervention is usually needed. This study utilized a national database to analyze readmission rates and factors associated with readmission in children with cerebral palsy undergoing hip surgery, aiming to improve the treatment for this population.
