INTRODUCTION: We sought to understand the impact of locum tenens surgeons on pediatric surgical care delivery. METHODS: We conducted a cross-sectional survey of Children's Hospital Association pediatric surgical practices. Anonymous electronic surveys were used to investigate locum tenens utilization, primary reason for use, limitations on clinical activities, and variations in practice standards or quality. Bivariate analysis and multivariable logistic regression were performed to evaluate for associations between practice characteristics and locum tenens use. RESULTS: Of 172 practices, 71% (n = 122) completed the survey. Median hospital size was 203 beds (interquartile range = 130-350). Median number of surgeons per practice was 5 (interquartile range = 3-8). Thirty-seven practices (30%) employed locum tenens at primary (n = 27) or satellite (n = 12) sites. Locum tenens utilization was higher in suburban (odds ratio [OR] = 3.78, P = 0.006) and rural (OR = 4.96, P = 0.041) locations and lower at sites with a level 4 neonatal intensive care unit (OR = 0.35, P = 0.035). Most (51%) used locum tenens ≥ 1 time monthly but <
1 time weekly and for ongoing or interim coverage (87%). In total, 14% of practices reported clinical restrictions for locum tenens surgeons, including limitations on extracorporeal membrane oxygenation, neonatal index cases, and operative trauma. Most (76%) practices using locum tenens reported variations in practice standards or quality
all were perceived as negative (57%) or neutral (43%). CONCLUSIONS: Locum tenens providers are utilized most commonly in suburban and rural sites and hospitals without the highest level of neonatal intensive care. While locum tenens surgeons may help maintain access to pediatric surgical care where gaps exist, there may be a need to improve the quality and reliability of care rendered.
