Wrong-sided and wrong-level neurosurgery: a national survey

Restricted access

Object

Perhaps the single greatest error that a surgeon hopes to avoid is operating at the wrong site. In this report, the authors describe the incidence and possible determinants of incorrect-site surgery (ICSS) among neurosurgeons.

Methods

The authors asked neurosurgeons to complete an anonymous survey. These surgeons were asked to report the number of craniotomies and lumbar and cervical discectomies performed during the previous year, as well as whether ICSS had occurred. They were also asked detailed questions regarding the potential determinants of ICSS.

Results

There was a 75% response rate and a 68% survey completion rate. Participating neurosurgeons performed 4695 lumbar and 2649 cervical discectomies, as well as 10,203 craniotomies. Based on this self-reporting, the incidence of wrong-level lumbar surgery was estimated to be 4.5 occurrences per 10,000 operations. The ICSSs per 10,000 cervical discectomies and craniotomies were 6.8 and 2.2, respectively. Neurosurgeons recognized fatigue, unusual time pressure, and emergent operations as factors contributing to ICSS. For spine surgery, in particular, unusual patient anatomy and a failure to verify the operative site by radiography were also commonly reported contributors.

Conclusions

Neurosurgical ICSSs do occur, but are rare events. Although there are significant limitations to the survey-based methodology, the data suggest that the prevention of such errors will require neurosurgeons to recognize risk factors and increase the use of intraoperative imaging.

    Pie charts indicating how often patients were informed of ICSS made during a 12-month period for wrong-sided craniotomies (A) and wrong-level discectomies (B).

  • View in gallery

    Pie charts revealing factors related to wrong-sided cranial surgery. Factors specifically related to wrong-sided cranial surgery were emergency operating conditions or surgery performed after hours (68% of cases, A), fatigue (19% of cases, B), and unusual time pressures to start or finish a procedure (42% of cases, C).

  • View in gallery

    Pie charts showing factors related to wrong-level spinal surgery. Factors specifically related to wrong-level spinal surgery included failure to use intraoperative x-ray films or image guidance to confirm spinal level (30% of cases, A) and unusual patient anatomy or physical characteristics (38% of cases, B).
