Decision making biases in the allied health professions: A systematic scoping review

Abstract: Objectives Cognitive and other biases can influence the quality of healthcare decision making. While substantial research has explored how biases can lead to diagnostic or other errors in medicine, fewer studies have examined how they impact the decision making of other healthcare professionals. This scoping review aimed to identify and synthesise a broad range of research investigating whether decisions made by allied health professionals are influenced by cognitive, affective or other biases.

“…Extensive literature highlights the presence of bias in clinical decision-making in allied health practice and the likelihood of inconsistencies and potential for suboptimal outcomes [ 21 , 26 , 45 ]. Indeed, decision-making remains a complex and multifaceted process [ 45 ] and gaps in our understanding continue to exist since most research pertains to clinical decision-making in medical [ 23 ] and psychology professions [ 26 ] or clinical errors [ 23 , 45 ]. Our findings contribute to existing knowledge of allied health resource allocation decision-making and we identified a key barrier that revolved around acceptance of evidence not aligning with prior expectations.…”

“…Internal inconsistency was noted, as was the inconsistency with established frameworks for forming recommendations based on research evidence (such as the GRADE criteria used by the Cochrane Collaboration [ 46 ]). These observations may be symptomatic of confirmation bias, which has been observed in many fields when evidence is presented that does not conform to prior expectations and beliefs [ 47 ] and affective bias, where a person’s emotional state influences decision outcomes [ 26 ]. Similarly, sunk cost bias was evident in that participants were more inclined to weekend service provision as a result of previously invested resources [ 48 ].…”

“…The quality of research evidence generally comes from the study design [14]. Formal risk of bias tools also exist to assist clinicians with appraising the quality of an individual study rather than simply relying on the evidence level [17].…”

“…(9,14,15) Improving clinical decision-making in the pursuit of quality and person-centeredness requires a clear understanding of relevant factors. While effort has gone into understanding this topic for a broader patient population, (16)(17)(18)(19) it is relatively unexplored for a more complex multimorbid population. We sought to clarify this evidence gap by conducting qualitative interviews with primary care physicians.…”
