RESUMEN
BACKGROUND: Operating theatres (OTs) are complex environments where team members complete difficult tasks under stress. Distractions in these environments can lead to errors that compromise patient safety. A range of potential distractions exist in OTs and previous research suggests they are common. This study assesses the nature, frequency and impact of distracting events in the OT at a tertiary New Zealand hospital. METHODS: Prospective observational study of the frequency, type and impact of OT distractions during a 3-month period. Two observational methods - the frequency of door openings and a validated tool - were used to categorize OT distractions for a range of acute and elective, paediatric and adult surgical procedures according to their cause and effect. RESULTS: There were 57 procedures (2037 intraoperative minutes) observed. During this time, 721 door openings and 1152 other distracting events were recorded. On average, either a door opening or other distracting event was recorded 56 times per hour of intraoperative time. The frequency of distractions did not vary in relation to acute versus elective or paediatric versus adult procedures but were more common in the morning. Communication unrelated to the case was the most common distracting event: these and equipment issues had the greatest effect on the entire surgical team, usually by causing some interruption to operative flow. CONCLUSION: Distractions in OTs were common, occurring nearly every minute. Most were trivial, but some had the potential to disrupt the operative procedure and result in patient harm. Reducing distractions in surgery could reduce patient harm and improve resource use.
