Occurrence and Duration of Interruptions During Nurses' Work in Surgical Wards: Findings From a Multicenter Observational Study.

This was an observational multicenter study of 50 registered nurses, randomly selected, on 5 surgical wards in 5 Italian hospitals. There were on average 5.6 interruptions per hour. Interruptions occurred more frequently during the afternoon shift (n = 1061; 52.8%), were caused mainly by the staff members (n = 978; 48.7%) during medication administration (n = 1075; 53.5%), and were managed directly by the nurses (n = 1639; 81.6%). The average duration of an interruption was 32.7 seconds (95% confidence interval, 30.7-34.7).
