Physician-patient communication following invasive procedures: an analysis of post-angiogram consultations

Although rarely studied, physician-patient interactions immediately following diagnostic tests are significant medical events because during these encounters the physician and patient often make decisions about major and sometimes invasive treatment. This investigation analyzed patterns of physician-patient communication following coronary angiography with particular attention to behaviors important to decision-making: physician information-giving, physician use of partnership-building, and active forms of patient participation (e.g., asking questions, being assertive, expressing concerns). We were particularly interested in effects related to the patient's race in light of documented evidence of racial disparities in cardiac care and outcomes. From audiotape recordings, 93 physician-patient interactions after coronary angiogram in a catheterization laboratory in a large US Veterans Affairs Medical Center were coded to measure the frequency of physicians' information-giving and partnership-building and the frequency of active patient participation. We also stratified these behaviors according to whether the behavior was prompted (e.g., physician information in response to a patient's question; a patient's opinion solicited by the doctor) or self-initiated. Several findings were noteworthy. First, these interactions were very brief and dominated by the physician. Second, although physician information-giving increased with more active patient participation, which in turn was correlated with physicians' use of partnership-building, proportionally little of the physicians' information (8%) and active patient participation (9%) was directly prompted by the other interactant. Finally, there was a tendency for physicians to self-initiate less information giving to black patients and for black patients to self-initiate less active participation than white patients. Although these differences were attenuated when other variables (e.g., the physician's training, disease severity) were included in the analysis, the pattern suggests a potential cycle of passivity where certain patients tend to receive fewer informational resources and these patients in turn do less to prompt the doctor for more.
