Does admission to a medical department improve patient life expectancy?
Doubts about the effectiveness of medical care in improving patient health have been raised by epidemiological studies and by studies of geographical variation and inappropriate use of health care. To investigate this problem, the life expectancy gain (LEG) from consecutive admissions to a department of internal medicine during a six-week period was assessed by two expert panels, each consisting of an internist, a surgeon, and a general practitioner. The mean LEG for all admissions was 2.25 years (n = 422). Sixty-one percent had a LEG of 0.10 years or less, while 5% had a LEG of more than 9.98 years. In a probabilistic sensitivity analysis, the mean LEG remained greater than zero under assumptions of overestimated positive LEG and underestimated negative LEG. We conclude that the life expectancy of the majority of the patients was not influenced by the admission, but that a minority had substantial gains, resulting in a high overall mean LEG.
