BackgroundThe utilization of locum tenens physicians in the United States has risen significantly as a stopgap for clinical practice needs, particularly in rural and other underserved areas. The difficulty in hiring new physicians to remote hospitals has resulted in the dependence of these institutions on locum tenens coverage. Here, we assess the quality and cost of neurosurgical care between locum and non-locum neurosurgeons in the United States, the first study in our knowledge to do so.MethodsA 5% random sample of the Medicare claims limited data set was queried for 2005-2011 for neurosurgical cases using International Classification of Diseases, Clinical Modification, 9th edition (ICD-9-CM) procedure codes for common cranial and spine procedures. Cases were divided into locum and non-locum groups using ICD modifier Q6. The association between locum care and 30-day surgical complications, disposition, and cost of care was evaluated.ResultsA total of 112,397 patients met inclusion criteria, with locum tenens practitioners involved in 164 (0.15%) cases. Locum and non-locum cohorts were statistically and clinically similar at baseline, with respect to comorbidity and case type. Mortality (0.00% vs. 0.19%; P=0.739), discharge disposition (P=0.739), surgical complication rates, and length of stay (8.74 ± 12.24 vs. 10.54 ± 15.51 days; P = 0.117) did not appear to differ significantly between the 2 groups. Hospitalization costs were also similar (158,780.20 ± 223,735.50 vs. 168,104.40 ± 308,074.90 USD; P = 0.698), as were amounts paid by patients (39,197.70 ± 14,144.75 vs. 39,234.36 ± 15,467.63 USD, P = 0.976).ConclusionsAmong Medicare beneficiaries, there exists no difference in short-term complication rates, lengths of hospitalization, or costs between locum and non-locum neurosurgeons.Copyright © 2020 Elsevier Inc.
