Socioeconomic disparities and trends in the utilization of regional and neuraxial anesthesia for pediatric femur fracture repair

Pediatric femur fractures often necessitate surgical intervention, with pain management being critical for both immediate and long-term outcomes. Peripheral nerve blocks (PNBs) and neuraxial techniques are effective in providing targeted pain relief while minimizing systemic opioid exposure. Despite their benefits, the utilization of these anesthesia techniques in pediatric orthopedic surgeries is limited, particularly among socioeconomically disadvantaged patients. This study aims to evaluate the association between socioeconomic status (SES) and the use of regional and neuraxial anesthesia in pediatric femur fracture repairs, focusing on healthcare resource utilization (HRU) outcomes such as hospital length of stay (LOS), total hospital charges, and discharge disposition. Using the 2016-2020 NIS database, we identified 43,605 pediatric patients who underwent femur fracture repair. Only 1 % received PNB, and 0.1 % received spinal block (SB). Our analysis revealed that PNB was less likely to be administered to patients from lower SES backgrounds, those with subtrochanteric fractures, or those requiring delayed repair. Conversely, PNB was associated with reduced HRU, while SB was linked to increased HRU. The findings underscore significant disparities in the application of regional anesthesia, influenced by socioeconomic factors. Our study highlights the need for standardized guidelines and interventions to address these disparities, ensuring equitable access to effective pain management techniques in pediatric orthopedic care. Further research is warranted to understand the barriers to the utilization of PNB and to develop strategies to enhance its adoption, particularly among underserved populations.
