摘要
Introduction While neurovascular surgeries have largely been performed by neurosurgeons, the advent of endovascular procedures has produced increasing involvement of other specialists in this arena (i.e. neurologists and radiologists).This study aims to analyzethe involvement of different specialties within theneuroendovascular workforce by characterizingthem by their primary specialty. Methods The Medicare Provider Utilization Database was queried from 2013 to 2019 for all primary Current Procedural Terminology (CPT) codes identified by the American Medical Association as pertaining to endovascular procedures of the nervous system (61623, 61624, 61630, 61635, 61626, 61645, and 61650). We counted the number of unique providers in respective fields (neurology, neurosurgery, and radiology) who performed these procedures. Statistical analyses, including data aggregation, exploratory analysis, and propensity adjustment, were performed using R, version 4.0.1 (The R Foundation, Vienna, Austria). The two‐sided Mann‐Kendall trend test, a non‐parametric statistical test that assesses for monotonic trends in either an upward or downward trend, was utilized to assess for trends over time. Within each year analyzed, a Chi‐squared test for trend in proportions was used. A significance level of 0.05 was used. Results In 2013, neurosurgeons comprised 45% of the workforce performing these procedures, neurologists were 9%, and radiologists were 47%. By 2019, neurosurgeons decreased to 34.5% of the workforce, while neurologists increased to 21.5%, and radiologists decreased slightly to 44%. Neurologists were the only field in which the proportional shift in providers was noted to have a significant change in trajectory (p:0.04), an upward trajectory. Overall proportional differences between respective specialists were statistically significant each year (p< 0.01). Conclusions Neurologists are increasingly performing endovascular procedures. Increased communication and coordination between specialties can improve disparities in care to ensure adequate access to neurovascular care across the US.
