From: A portable mnemonic to facilitate checking for cognitive errors
TWED Checklist | Classification of cognitive errors covered (based on Campbell et al. 2007) | Rationale |
---|---|---|
T = life or limb Threat (What are the life or limb threatening conditions in this patient?) | Cognitive errors due to failure to consider alternative diagnoses (worst-case scenarios) | This domain encapsulates the rule-out-worse-case scenarios (ROWS) heuristics as a form of cognitive forcing strategy |
W = Wrong? (What if I am wrong? What else could it be?) | Cognitive errors due to overattachment to a particular diagnosis and cognitive errors due to failure to consider alternative diagnoses | This domain is to reduce the risk of committing cognitive errors such as search satisficing, anchoring, confirmation, availability biases, etc. |
E = evidences (Do I have sufficient evidences for or against this diagnose?) | Cognitive errors due to inheriting someone else’s thinking and cognitive errors due to erroneous estimation or perception of prevalence | This domain is to minimize cognitive errors such as anchoring, confirmation bias, blind spot, myside bias, ego bias, etc. |
D = dispositional factors (What are the environmental & emotional (2es) dispositions influencing my decision?) | Environment influences are not explicitly listed as one of the categories but discussed in this paper as error-producing conditions (EPC). These are high-pressured conditions that often exist by necessity, but are prone to cognitive errors because of the expectation to shorten the decision making process | These are the factors that may increase the risk of committing cognitive errors. These can be further divided into 2 ‘E’s: the environmental factors—e.g., chaotic, busy working place; and the ‘emotional factors’. These emotional factors can come from the physician or from the patient |
