Power Failures During Surgery: A 2000-2019 Review of Reported Events in the Veterans Health Administration

Objectives The frequency and impact of power failure on surgical care over time in a large integrated healthcare system such as the Veterans Health Administration (VHA) is unknown. Reducing the likelihood of harm related to these rare but potential catastrophic events is imperative to ensuring patient safety and high-quality surgical care. This study provides analysis and description of reported power failures during surgery (January 2000-March 2019), in the VHA and their impact. Methods This quality improvement study describes patient safety adverse events related to power failure in the operating room reported by 63 VHA medical centers from the approximately 137 VHAs with a surgical program. Power failure events during surgery reported to the VHA National Center for Patient Safety are analyzed. Results The authors identify 20 root cause analyses and 135 safety reports. Most events 36.1% (n = 56) resulted from generator delay, equipment reboot delay 21.9% (n = 34), and equipment backup power failure 13.5% (n = 21). Root causes include issues with backup batteries or equipment, engineering and clinical staff communication, standardized procedures for testing power, backup power delay, electrical circuit issues, documentation, and training. Patient harm occurred in 18% (n = 28) and 3.9% (n = 6) as major or catastrophic. Conclusions Power failure during surgery is associated with major or catastrophic patient harm, though rare. Staff preoccupation with failure, disaster preparedness, and focus on communication has the potential to minimize or avoid patient harm.
