Impact of interruptions on the duration of nursing interventions: A study in a chemotherapy unit

Abstract

Objective: To investigate interruptions during nursing interventions in a chemotherapy unit (sources and causes); measure their frequency, duration and the total elapsed time to complete the interventions. Method: This is an observational analytical study performed using a digital stopwatch. It was conducted in a teaching hospital between 2015/2016. The interventions performed and their interruptions were mapped and classified according to the Nursing Interventions Classifications (NIC) taxonomy. Results: There were 492 interruptions recorded in the 107 hours observed, especially in indirect care interventions. They were mainly caused by nursing professionals (n = 289; 57.3%) to supply materials (n = 65; 12.8%) and exchange care information (n = 65; 12.8%). The duration of interruptions ranged from 0:08 to 9:09 (average 1:15; SD 1:03) minutes. On average, interventions took 2:16 (SD 0:27) minutes to complete without interruption; however, the average was 5:59 (SD 3:01) minutes when interrupted. Conclusion: The interruptions were constant during the nursing work in the chemotherapy unit, including during the preparation and administration of medications, and increased the time to complete the interventions by an average of 163.9%.
