Diagnostic errors occur for many reasons, some of which are based in cognitive biases. Also called cognitive dispositions to respond (CDR), these can result from failures in perception, faulty mental shortcuts, or unconscious biases, and clinicians are usually unaware they exist. This article discusses the influence CDRs have on clinical decisions and walks you through methods for purposeful debiasing.
Conclusion
This article reminds health care providers that cognitive biases can influence clinical decision-making. Clinicians should be aware of how System 1 and System 2 thinking couple with unconscious cognitive biases to affect clinical decisions and patient safety. Once a provider identifies a bias, he or she should attempt to employ one or more debiasing techniques. Medical decision errors usually occur due to multiple factors, and one thinking mode is not more error prone than the other (analytic versus intuitive). Cognitive errors are also caused by knowledge gaps and faulty patient data processing. Future research is needed to assess outcomes of quality improvement projects that include these components.
