Mapping registered nurse anaesthetists' intraoperative work: tasks, multitasking, interruptions and their causes, and interactions: a prospective observational study

Abstract

<p>Introduction <br></p><p>Safe anaesthesia care is a fundamental part of healthcare. In a previous study, registered nurse anaesthetists (RNAs) had the highest task frequency, with the largest amount of multitasking and interruptions among all professionals working in a surgical team. There is a lack of knowledge on how these factors are distributed during the intraoperative anaesthesia care process, and what implications they might have on safety and quality of care. <br></p><p>Objective <br></p><p>To map the RNAs' work as done in practice, including tasks, multitasking, interruptions and their causes, and interactions, during all phases of the intraoperative anaesthesia work process. <br></p><p>Methods <br></p><p>Structured observations of RNAs (n=8) conducted during 30 procedures lasting a total of 73 hours in an operating department at a county hospital in Sweden, using the Work Observation Method By Activity Timing tool. <br></p><p>Results <br></p><p>High task intensity and multitasking were revealed during preparation for anaesthesia induction (79 tasks/hour, 61.9% of task time spent multitasking), anaesthesia induction (98 tasks/hour, 50.7%) and preparation for anaesthesia maintenance (86 tasks/hour, 80.2%). Frequent interruptions took place during preoperative preparation (4.7 /hour), anaesthesia induction (6.2 /hour) and preparation for anaesthesia maintenance (4.3 /hour). The interruptions were most often related to medication care (n=54, 19.8%), equipment issues (n=40, 14.7%) or the procedure itself (n=39, 14.3%). RNAs' work was conducted mostly independently (58.4%), but RNAs interacted with multiple professionals in and outside the operating room during anaesthesia. <br></p><p>Conclusion <br></p><p>The tasks, multitasking, interruptions and their causes, and interactions during different phases illustrated the RNAs' work as done, as part of a complex adaptive system. Management of safety in the most intense phases-preparing for anaesthesia induction, induction and preparing for anaesthesia maintenance-should be investigated further. The complexity and adaptivity of the nature of RNAs' work should be taken into consideration in future management, development, research and education.</p>
