Computer assessment of life-style in a gastroenterology clinic

To examine the potential benefit of a computer-assisted interview about life-style in gastroenterology practice, 34 consecutive patients attending a gastroenterology clinic were questioned by a computer using software designed to obtain a comprehensive history of alcohol, caffeine, cigarette, and illicit drug use, together with an assessment of exercise, sexual activity, and nutrition. Comparisons of the information obtained by the computer with clinical records revealed that physicians documented only 3% of the patients as problem drinkers, 3% as caffeine abusers, and 17% as smokers, whereas the computer identified 10% of the patients as problem drinkers, 27% as caffeine abusers, and 43% as smokers. These findings imply that patients may be more apt to tell more about adverse life-style to the computer than to a physician during clinical interview. In a sample patient population from a gastroenterology clinic, a microcomputer provides an acceptable, efficient, and potentially cost-effective way to assess life-style.
