Abstract

Background and objectives: The primary objective of this study was to evaluate the influence of operating room nurse (ORN) characteristics on the duration of elective neurosurgical procedures in adults. In addition, we conducted a cost-benefit analysis of various strategies for organizing the workflow of ORNs.

Methods: We collected and analyzed operating times for adult elective neurosurgical procedures, categorizing them by surgeon, procedure complexity (dichotomized as technologically complex and simple), and ORN characteristics (dichotomized as ORN dedicated to neurosurgery [dORN] and ORN not dedicated to neurosurgery [ndORN]). The monetary valuation of operating times is based on the unitary cost per minute of the operating room, including opportunity costs of ORN, as well as their training costs and salaries. Cost-benefit analysis adopted the hospital perspective.

Results: Analysis of operating times reveals an approximately 20-minute difference for complex procedures when performed with ndORN. However, there is no significant difference in operating times for simple procedures, whether they are conducted by dORN or ndORN. The additional annual cost incurred by complex procedures performed with ndORN is estimated at CHF 68 144.4 for the Geneva University Hospitals.

Conclusion: Complex neurosurgical procedures exhibit shorter durations when performed by dORNs. We explore several hypotheses to explain this difference. By adapting available human resources and optimizing workflow organization, hospitals can potentially achieve a net benefit.
