Factors associated with the use of regional anesthesia for calcaneal osteotomy in pediatric patients: A single-center, retrospective cohort study.

Despite known disparities in pediatric perioperative outcomes, few studies have examined factors associated with the use of regional anesthesia for pediatric orthopedic surgery.This investigation aimed to determine if minority and developmental disability status were associated with the allocation of peripheral nerve blocks in calcaneal osteotomy.We conducted a single-center, retrospective study of records of patients <18 years who underwent calcaneal osteotomy from 2013 to 2023. Regional technique was classified into three groups: popliteal-sciatic single-shot block, popliteal-sciatic catheter, and no block. Patients were classified as either nonminority (white, non-Hispanic) or minority. Developmental disability status was defined based on medical history and classified as binary. Anesthesiologists were classified as "regional" or "nonregional" based on clinical expertise. A Bayesian hierarchical multinomial model with random intercepts for patients and surgeons was used to investigate the association of minority status, developmental disability, and anesthesiologist expertise with block selection.We analyzed 287 cases in 225 patients; of these, 55% occurred in minority patients and 28% occurred in patients with developmental disability. Catheters were placed in 45% of cases, single shot blocks in 41%, and no block in 14%. Minority and nonminority patients had a similar likelihood of receiving of any block. Patients with developmental disability had a -22% absolute difference of receiving any block (95% credible interval [-38%, -7%]) compared to those without developmental disability (55% vs. 77%), an effect primarily driven by a lower rate of catheter placement in these children. Regional anesthesiologists were more likely to place catheters (23% absolute increase; 36% vs. 13%) and more likely to perform any block in children with developmental disability (30% absolute increase; 67% vs. 37%) than nonregional anesthesiologists.Decision-making surrounding the placement of regional anesthesia techniques is complex. In this study, developmental disability status and anesthesiologist experience were associated with a difference in the use of regional anesthesia in patients undergoing calcaneal osteotomy.
