Comparing complications of outpatient management of slipped capital femoral epiphysis and Blount’s disease: A database study

BACKGROUND: Currents trends in pediatric orthopaedics has seen an increase in surgeries being successfully completed in an outpatient setting. Two recent examples include slipped capital femoral epiphysis (SCFE) and Blount’s disease. Surgical indications are well-studied for each pathology, but to our knowledge, there is an absence in literature analyzing safety and efficacy of inpatient vs outpatient management of either condition. We believed there would be no increase in adverse outcomes associated with outpatient treatment of either conditions. AIM: To investigate whether outpatient surgery for SCFE and Blount’s disease is associated with increased risk of adverse outcomes. METHODS: The 2015-2017 American College of Surgeons National Surgical Quality Improvement Program Pediatric Registries were used to compare patient characteristics, rates of complications, and readmissions between outpatient and inpatient surgery for SCFE and Blount’s disease. RESULTS: Total 1788 SCFE database entries were included, 30% were performed in an outpatient setting. In situ pinning was used in 98.5% of outpatient surgeries and 87.8% of inpatient surgeries (P < 0.0001). Inpatients had a greater percent of total complications than outpatients 2.57% and 1.65% respectively. Regarding Blount’s disease, outpatient surgeries constituted 41.2% of the 189 procedures included in our study. The majority of inpatients were treated with a tibial osteotomy, while the majority of outpatients had a physeal arrest (P < 0.0001). Complications were encountered in 7.4% of patients, with superficial surgical site infections and wound dehiscence being the most common. 1.6% of patients had a readmission. No differences in complication and readmission risks were found between inpatients and outpatients. CONCLUSION: The current trend is shifting towards earlier discharges and performing procedures in an outpatient setting. This can be safely performed for a large portion of children with SCFE and Blount’s disease without increasing the risk of complications or readmissions. Osteotomies are more commonly performed in an inpatient setting where monitoring is available.
