Abstract
Pivot and cluster strategy (PCS) is a cognitive forcing strategy designed to achieve diagnostic accuracy through the analytical deployment of a cluster of differential diagnoses (Cluster) specific to the initial most likely diagnosis (Pivot) recalled by a clinical diagnostician. This approach has been widely implemented and has effectively decreased diagnostic errors. Kahneman etal. have introduced innovative notions of noise and decision hygiene. Noise refers to the variance of errors, with numerous individuals' errors in judgment pointing in different directions. They suggest a "Decision Hygiene" (DH) template, w preventative technique meant to reduce noise in decision-making. This paper introduced an interpretation of the existing strategy of PCS from new perspectives of noise and DH, which would allow us to further understand the usefulness of PCS, thereby contributing to a positive effect on the quality of diagnosis.
