Abstract
Automation bias (AB)—the tendency to over-rely on automation—has been studied in various academic fields. Clinical decision support systems (CDSS) aim to benefit the clinical decision-making process. Although most research shows overall improved performance with use, there is often a failure to recognize the new errors that CDSS can introduce. With a focus on healthcare, a systematic review of the literature from a variety of research fields has been carried out, assessing the frequency and severity of AB, the effect mediators, and interventions potentially mitigating this effect. This is discussed alongside automation-induced complacency, or insufficient monitoring of automation output. A mix of subject specific and freetext terms around the themes of automation, human–automation interaction, and task performance and error were used to search article databases. Of 13 821 retrieved papers, 74 met the inclusion criteria. User factors such as cognitive style, decision support systems (DSS), and task specific experience mediated AB, as did attitudinal driving factors such as trust and confidence. Environmental mediators included workload, task complexity, and time constraint, which pressurized cognitive resources. Mitigators of AB included implementation factors such as training and emphasizing user accountability, and DSS design factors such as the position of advice on the screen, updated confidence levels attached to DSS output, and the provision of information versus recommendation. By uncovering the mechanisms by which AB operates, this review aims to help optimize the clinical decision-making process for CDSS developers and healthcare practitioners.
Here are some thoughts:
This systematic review examines the frequency, mediators, and mitigators of automation bias, which is the tendency for users to over rely on automated decision support systems as a heuristic replacement for vigilant information seeking and processing. The authors reviewed 74 studies across healthcare, aviation, and human computer interaction fields and found that automation bias is a robust effect, with a meta analysis showing that erroneous clinical decision support system advice increased the risk of incorrect decisions by 26%. Key mediators include user factors such as cognitive style, trust, confidence, and task specific experience, as well as environmental factors like workload, task complexity, and time pressure that strain cognitive resources. Mitigators include increasing user accountability, providing training, updating confidence levels alongside advice, positioning advice less prominently on screen, and presenting information rather than direct recommendations. The review concludes that automation bias and the related concept of automation induced complacency represent distinct but overlapping attentional phenomena that can introduce new errors even when decision support systems improve overall performance, highlighting the need for careful design and implementation strategies.
