Better, More Cost-Effective Intake Interviews
January/February 1998 (vol. 13 no. 1)
pp. 40-48

In primary-care medicine, physicians often treat patients they are encountering for the first time. After hearing a patient's complaint in an emergency room or outpatient clinic, the physician begins to narrow the list of possible causes for the patient's symptoms. In this differential diagnosis process, an experienced doctor usually needs only a few questions to identify a narrow list of candidate causes for a patient's chief complaint. However, the demands on the typical medical expert's time are great, so such interviews can be expensive, hurried, and incomplete.

This article describes how PISA, the Patient Interview Support Application, can improve the quality of primary-care medicine, contain costs, and, in particular, produce better medical records. PISA allows a person without medical training to take a patient's clinical medical history without the help of a nurse or physician. It emulates the doctor's ability to rapidly narrow the domain of inquiry while also accruing a thorough clinical record regarding the status of the patient's physical systems that are relevant to his or her complaint.
