During daily hospital ward rounds, medical teams, led by doctors, assess the progress of an individual patient's health. It is widely reported in the research literature that nurses play a relatively passive role during these rounds, because although they may have valuable information about the patient's condition and progress, and indeed their role includes advocacy on behalf of their patients, nurses nevertheless can experience difficulties in participating during case constructions. Here we report an instance from a (gastro-surgical) ward round in a Finnish hospital, in which nurses played a key role in reversing a consultant's initial decision to discharge a patient. They did so not by directly challenging the consultant's opinion, but by employing indirect means to introduce their discrepant perspective: they provide descriptions and ask questions that draw attention to information that results in the doctor coming to a different assessment than theirs of the patient's condition, and a different decision about what should be done (the patient was not discharged from hospital). The encounter reported here is taken from a corpus of ward round discussions in a Finnish hospital. The method of our study is Conversation Analysis.
