Abstract

Background: Despite known disparities in pediatric perioperative outcomes, few studies have examined factors associated with the use of regional anesthesia for pediatric orthopedic surgery.

Aims: This investigation aimed to determine if minority and developmental disability status were associated with the allocation of peripheral nerve blocks in calcaneal osteotomy.

Methods: 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.

Results: 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.

Conclusions: 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.
