Does admission to a department of internal medicine improve patients' quality of life?

OBJECTIVES: The Tromsø Medical Department Health Benefit Study was designed to estimate health gains from admissions to a department of internal medicine. We have previously reported that the hospital stays had no effect on the life expectancy of 61% of the patients. However, it has been claimed that modern medicine has a greater effect on quality of life (QoL) than on life expectancy. The aim of the present study was to investigate this issue by estimating gains in QoL for patients admitted to a department of internal medicine. DESIGN: The time trade-off method (TTO) was used for assessing QoL gain from consecutive admissions during a 6-week period. The assessments were made by one of two expert panels, each consisting of an internist, a surgeon and a general practitioner, on the basis of summaries of all relevant clinical information about the patients. Short-term improvements in QoL during the stay or shortly after discharge were scored on an ordinal scale. RESULTS: Of the admitted patients, 41% had gains in QoL measured with the TTO (mean gain = 0.06; 95% confidence interval = 0.05-0.07; n = 422), and eight of these had gains equal to or greater than 0.50. Another 40% had gains in health-related short-term QoL measured with the ordinal scale. In a multivariate linear regression analysis, emergency admissions, high age and the disease categories 'endocrinological diseases' and 'pneumonia and influenza', were associated with higher gain, and 'undiagnosed symptoms' and 'cerebrovascular diseases' with lower gain. CONCLUSIONS: As judged by the expert panels, the investigated department of internal medicine was effective in improving the QoL of 81% of the admitted patients. Whilst most of the patients achieved small gains, a minority had gains in QoL corresponding to the treatment of life-threatening diseases.

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.

Assessing health benefit from hospitalization. Agreement between expert panels.

Agreement between two expert panels in assessing gain in life expectancy and quality of life from unselected stays in a department of internal medicine was investigated. Weighted kappa statistics of 0.45 for gain in life expectancy and 0.63 for gain in quality of life were found.
