Annual Number of Spinal Cord Stimulation Procedures Performed in the State of Florida During 2018: Implications for Establishing Neuromodulation Centers of Excellence

OBJECTIVE:To assess the volume of spinal cord stimulation procedures performed by physicians in the state of Florida in 2018.MATERIALS AND METHODS:We obtained information from publicly available state databases for all patients undergoing procedures in 2018 at Florida hospitals, hospital-owned facilities, and independent ambulatory surgery centers. Cases in which a spinal cord stimulation procedure was performed were identified. We estimated for each physician office-based spinal cord stimulation trials (not subject to state reporting) based on the published Florida conversion factor of 25.6% of the total number of such procedures. The medical specialty of the listed performing physician was determined based on the national provider identifier. Counts of neurostimulation procedures performed by physician and within specialties were determined. The numbers of physicians and specialties performing various thresholds between 1 and ≥100 per year were determined, and the percentages of patients whose care was delivered by physicians below each threshold were determined.RESULTS:The data analyzed included 10,762 spinal cord stimulation cases. Among the 606 physicians who performed at least one spinal cord stimulation procedure, only nine performed at least 100 cases in 2018. During 2018, 78.4% of physicians performed, on average, <2 spinal cord stimulation procedures per month; there were 29.4% of spinal cord stimulation patients cared for by such physicians. Physicians performing less than four cases per month provided care for 56.9% of all cases.CONCLUSIONS:Few physicians performing spinal cord stimulation procedures in the state of Florida in 2018 would have been considered as "high volume." Although volume is only one among many criteria used to designate centers of excellence for other procedures, the potential impact on physician practice and patient access to care should be considered if a specific minimum number of annual cases by physician is to be established.
