The side effects of interferon-alpha for chronic hepatitis C are well-known. Patients may differ with respect to their tolerance of these side effects and also with respect to their individual preferences. We administered a brief questionnaire to 67 outpatients with hepatitis C virus infection. Patients were asked to make hypothetical choices between six-month profiles of health. The results were as follows: (1) patients preferred to expedite rather than postpone intervals of poor health; (2) preferences of patients with low quality-of-life were quite similar to preferences of healthier patients; (3) patients' choices satisfied transitivity; (4) patients' choices satisfied preferential independence; and (5) patients gave a variety of reasons for their choices. These results corroborate other investigations of health preferences, and serve to introduce the field of preference elicitation to gastroenterologists.
