ReviewStress and decision-making in resuscitation: A systematic review
Abstract
Background
During resuscitation decisions are made frequently and based on limited information in a stressful environment.
Aim
This systematic review aimed to identify human factors affecting decision-making in challenging or stressful situations in resuscitation. The secondary aim was to identify methods of improving decision-making performance under stress.
Methods
The databases PubMed, EMBASE and The Cochrane Library were searched from their commencement to the 13th of April 2019. MeSH terms and key words were combined (Stress* OR “human factor”) AND Decision. Articles were included if they involved decision makers in medicine where decisions were made under challenging circumstances, with a comparator group and an outcome measure relating to change in decision-making performance.
Results
22,368 records in total were initially identified, from which 82 full text studies were reviewed and 16 finally included. The included studies ranged from 1995 to 2018 and included a total of 570 participants. The studies were conducted in several different countries and settings, with participants of varying experience and backgrounds. Of the 16 studies, 5 were randomised controlled trials, 3 of which were deemed to have a high risk of bias. The stressors identified were (i) illness severity (ii) socio-evaluative, (iii) noise, (iv) fatigue. The mitigators identified were (i) cognitive aids including checklists, (ii) stress management training and (iii) meditation.
Conclusions
Human factors contributing to decision-making during resuscitation are identified and can be mitigated by tailored stress training and cognitive aids. Understanding these factors may have implications for clinician education and the development of decision-support tools.
