BackgroundThe evolution of neurosurgery in our center comprises 2 active phases separated by a decade-long latent phase. This study evaluates our experience in the renaissance phase using 1025 cases. We identify paradigms that predict progress under existing practice conditions.MethodsA prospective observational study was undertaken of all freshly operated patients from 2009 to 2016. Ethical approval was obtained from the hospital institutional review board. Data of enrolled patients were acquired and analyzed using SPSS software for Windows version 21. Inferences were evaluated using a 95% level of significance. Major and intermediate cases were included, whereas bedside cases as well as patients operated on elsewhere were excluded.ResultsOf 5132 patients treated, 3033 had surgical lesions, 1129 (33.2 ± 2.7% confidence limit [CL]) were operated on, and 1025 satisfied the study criteria. The unmet surgical load (66.1%) was significant (χ2 = 10.9; degree of freedom = 1; P = 0.001). The most common diseases treated were neurotrauma in 438 patients, congenital malformations in 268, and tumors in 170. The mean annual operative rate was 125 ± 5.7 patients (95% CL). Cases showed significant variability using 1-way analysis of variance (F = 13.77; P = 0.03). Residency training was a positive influence on surgeons' operative rate (χ2 = 7.59; P = 0.02). The mean complication rate was 10.3% ± 2.9%, and the mortality was 5.5% ± 1.7%.ConclusionsWe found a large unmet neurosurgical load. To resolve this situation, we recommend an increase in the number of training programs for neurosurgery residency. As neurosurgery units evolve, their progress may be evaluated using the NESCAPE (Neurosurgery Care Phase Evolution) paradigm.Copyright © 2018. Published by Elsevier Inc.
