%X This paper conceptualizes the act of diagnosis in primary care as a 'diagnostic moment,' comprising a diagnostic utterance in a 'diagnostic slot,' together with a patient response. Using a dataset of 201 treated conditions drawn from 255 video recorded medical visits with 71 physicians across 33 clinical practices in the Western United States, we investigate the incidence of diagnostic moments, aspects of their verbal design, and patient responsiveness. We find that only 53% of treated conditions in the dataset are associated with a diagnostic moment. Physicians present 66% of these diagnoses as hedged or otherwise doubtful, and deliver 30% of them without gazing at the patient. In the context of these diagnostic moments, patients are non- or minimally responsive 59% of the time. These findings underscore the different significance that may be accorded diagnosis in primary care in contrast to care in other medical contexts. The paper concludes that the analysis of sequences of action which empirically realize diagnosis are underrepresented in the sociology of diagnosis, and that better understanding of the diagnostic moment would enhance our understanding of diagnostic processes in primary care.
