Surgical complications are common and frequently preventable. The introduction of the WHO Surgical Safety Checklist has improved surgical outcomes. WHO guidelines reduce, but do not prevent errors. Successful arthroplasty surgery requires strict infection control measures. We observed a single surgical team to see if errors caused by operating room personnel were covered by the WHO Checklist. Two independent observers studied compliance of WHO Checklists and operating room etiquette, for one surgical team. All operating room personnel were observed during thirteen arthroplasties (hips and knees) from induction to recovery. All Personnel were blinded to the purpose of this study. Data was categorised into errors with WHO checklists and operating room etiquette.Purpose
