Time-Out and Its Role in Neurosurgery

Abstract

Background: Safety checklists have improved surgical outcomes; however, much of the literature comes from general surgery.

Objective: To identify the role of time-outs in neurosurgery, understand neurosurgeons' attitudes toward time-out, and highlight areas for improvement.

Methods: A cross-sectional study using a 15-item survey to evaluate how time-outs were performed across 5 hospitals affiliated with a single neurosurgery training program.

Results: Surveys were sent to 51 neurosurgical faculty, fellows, and residents across 5 hospitals with a 72.5% response rate. At all hospitals, surgeons, anesthesiologists, registered nurses, and circulators were involved in time-outs. Although all required time-out before incision, there was no consensus regarding the precise timing of time-out, in policy or in practice. Overall, respondents believed the existing time-out was adequate for neurosurgical procedures (H1: 17, 65.4%; H2: 19, 86.4%; H3: 14, 70.0%; H4: 20, 80.0%; and H5: 18, 78.3%). Of the respondents, 97.2% believed time-out made surgery safe, 94.6% agreed that time-outs reduce the risk of wrong-side or wrong-level neurosurgery, and 17 (45.9%) saw a role for a neurosurgery-specific safety checklist. Pragmatic challenges (n = 20, 54.1%) and individual beliefs and attitudes (n = 20, 54.1%) were common barriers to implementation of standardized time-outs.

Conclusion: Multidisciplinary time-outs have become standard of care in neurosurgery. Despite proximity and overlapping personnel, there is considerable variability between hospitals in the practice of time-outs. This lack of uniformity, allowed for by flexible World Health Organization guidelines, may reflect the origins of surgical time-outs in general surgery, rather than neurosurgery, underscoring the potential for time-out optimization with neurosurgery-specific considerations.
