Content and process in clinical decision-making by nurse practitioners.

Clinical decision-making is the process nurses use to gather information, evaluate it and make a judgment that results in the provision of patient care. This research sought to increase our understanding of clinical decision making by nurse practitioners. The sample consisted of 27 nurse practitioners; 6 OB/GYN nurse practitioners, 11 experienced family nurse practitioners and 10 inexperienced family nurse practitioners. All subjects cared for the same patient who was presented via computer and interactive video. Findings indicated that nurse practitioners use a process of clinical decision-making in which diagnostic hypotheses drive data acquisition. The OB/GYN nurse practitioners were more likely to develop lists of diagnostic hypotheses which reflected the patient's chief complaint, while both experienced and inexperienced family nurse practitioners were more likely to acquire subjective and objective data that did not appear to be hypothesis driven.
