Document Summary

This particular combination of methods is a bit unusual. Study: examine how physicians" interpretations of patient sex-gender affect diagnostic certainty and, in turn, decision making for coronary heart disease: methods: mixed-method vignette-based experimental design. A factorial experiment of 256 physicians who viewed i of 16 video vignettes with different patient-actors presenting the same symptoms of coronary heart disease, with the same words and hand gestures. After viewing video, physicians provided their diagnosis, certainty for each diagnosis on scale of 0-100. Physicians completed a structured interview and provided a narrative about their decision-making process and management plan. Diagnostic uncertainty reduces the likelihood that physicians will order tests and medications appropriate for an urgent cardiac condition in particular. Not much of a difference here between male and female patients". Qualitative: physicians interpreted the same symptom presentation (same script, same gestures) differently for men and women.
