This study seeks to assist in setting priorities for assessing medical practices and technologies when assessment resources are scarce. It develops an objective index of expected gain from technology assessment, using modified DRG-level data on hospitalizations in NY State. The index uses standard economic concepts to combine measures of resource use, the coefficient of variation in use rates across regions, and the rate at which the incremental value of a medical intervention changes as its rate of use changes, providing a dollar-valued welfare loss from variations. For the entire US in 1987, the highest index occurred for coronary artery bypass graft ($0.95 billion per year), but most of the high-index interventions were nonsurgical, including hospitalizations for psychosis ($0.74 billion per year), cardiac catheterization ($0.62 billion per year), chronic obstructive lung disease ($0.55 billion per year), angina pectoris ($0.46 billion per year), adult gastroenteritis ($0.38 billion per year), adult pneumonia ($0.32 billion per year) and medical back problems ($0.28 billion per year). The top 25 interventions create an annual welfare loss of exceeding $7 billion. The present value of convincingly assessing the correct way to use these interventions sums many years of annual gains from eliminating these welfare losses. The gains from eliminating unexplained variation in medical practices appear greatly larger than costs of necessary studies.

The prevalence of comorbidities in patients dismissed from hospitals has already been investigated to obtain economical, administrative and epidemiological information, or for health insurance-related problems. Originally designed for billing purposes, administrative data could be the basis for clinical research as well, although the clinical element has somehow been disregarded till now. The aim of this research is (i) to study the prevalence, and (ii) to evaluate the clinical relevance of comorbidities in patients dismissed from a Department of Internal Medicine. In a recent series of 1605 patients (since the Diagnosis-Related Groups-DRG-based hospital financing system has come into common use in Italy) comorbidities have been observed in 92.65% of the cases, while the percentage of comorbidities was rated as 71.97% in a previous series of 2551 patients dismissed from the same Department before the introduction of the DRG system. In the recent series, the prevalence of a single comorbid condition and of two and of three comorbid conditions was 19.50, 32.89 and 47.61%, respectively. In any case, the so-called comorbid conditions were active diseases requiring medical investigation and therapy. They included hypertensive heart disease, ischemic heart disease and angina, arrhythmias, peripheral vascular diseases, chronic bronchitis, chronic hepatitis, liver cirrhosis, diabetes, metabolic disorders, etc. In conclusion, patients referred to a Department of Internal Medicine have a high severity of illness due not only to the gravity of the primary diagnosis but also to the number and seriousness of comorbid conditions. For these patients more hospital resources and a high level of professional skill are required.

This paper demonstrates the basic properties in the systems most commonly considered for costing treatments in the Danish hospitals. The differences between the traditional charge system, the DRG system and the ABC system are analysed, and difficulties encountered in comparing these systems are discussed. A sample of patients diagnosed with stable angina pectoris (SAP) at Odense University Hospital was used to compare the three systems when costing an entire treatment path, costing single hospitalisations and studying the effects of length of stay. Furthermore, it is illustrated that the main idea behind each system is reflected in how the systems over- or underestimate costs. Implications when managing the hospitals, particularly reimbursement, are discussed.
