Factors Influencing the Interruption of Nursing Document Writing in the Intensive Care Unit: A Cross-Sectional Survey

Objective: To explore the current status of interruption events in nursing document writing in the intensive care unit (ICU) using a cross-sectional survey. Methods: Between May and October 2021, the convenience sampling method was used to observe the interruption events in nursing document writing in the ICU. A total of 54 nurses and 7 indicators were observed: the start time, end time, interruption period, source, type, duration and outcome of interruption events. Results: A total of 438 interruption events in nursing document writing occurred in 85.955 hours, with a frequency of 5.093 times/hour and a duration of 4787.00 (1152.00, 13,109.00) seconds. The frequency of interruption events in nursing document writing was the highest (11 times/hour) and the duration was the longest (9581.50 seconds) from 08:00 to 12:00. The main sources of interruptions for nurses with 10 or more years of service or with the professional title of nurse are nurses themselves and their colleagues. The main sources of interruptions for nurses who have been in charge for 10 years or over are the working environment and doctors. This intervention in work continuity occurs unexpectedly; however, if adjustments are made to nursing procedures, the interruption can be terminated rapidly or adverse consequences can be avoided. Years of working experience, seniority level, interruption time periods and professional titles were independent factors influencing the number of interruption events, and they were all positively correlated. The results of this study show that there were statistically significant differences in the incidence of negative outcomes among ICU nurses with varying years of working experience and professional titles. Conclusion: Interruptions in nursing document writing have high frequency, complex sources and multiple types. For senior nurses, the outcome was predominantly positive, while for junior nurses, it was predominantly negative.
