The impact of interruptions on the duration of nursing interventions: a direct observation study in an academic emergency department

This study analyses the effect of interruptions to care provided by nurses and clinical technicians on the length of clinical procedures and interventions (excluding the length of the interruption). Methods An observational time study of the effect of interruptions on common nursing interventions in the emergency department (ED) of a large academic medical centre was conducted. This study used direct observations of nurses and clinical technicians while delivering care to patients. Results The average time spent on an uninterrupted intervention was 296.47 s (median:185.15, SD:319.05), while interrupted interventions took 682.02 s (median:589.63, SD:504.59). Controlling for intervention type and other potential confounding factors using multiple linear regression found that interrupted interventions were 121.36 s (95% CI 79.57 to 163.15) longer, a 19 percentage point increase (95% CI 11.31 to 26.89), than an intervention without (excluding the length of the interruption). Family/patient interruptions effected duration the most while staff interruptions affected the intervention time the least. Discussion Our findings are consistent with outcomes of studies in non-healthcare domains, but are contrary to a study of ED physicians, suggesting differential responses to interruptions by physicians and nurses. Future studies on interruptions in healthcare should thus be discipline specific. Though the effect of interruptions on intervention length is only about 2&nb...
