Money consuming monuments or efficient echelons?--Assessing the economic role of hospitals in national health care systems.

A comprehensive cost-benefit analysis of a national health care system would due to conceptual reasons and formidable technical problems result in crude or disputable estimates. Therefore, this paper argues that an economical assessment cannot avoid delineating health care into its different sectors, and looking into them separately. An analysis of the hospital sector is suggested to be pursued in the following order: First, the proportion of total health care expenditure allocated to hospitals is calculated. Second, cost per service is measured and the relative importance of input factors on that estimate of internal efficiency (productivity) are analysed. Third, distribution of service utilisation is determined, relating it to structural and demographic variables. Fourth, the impact of funding mechanisms is noted as an important marginal condition for economical performance. The paper discusses methods for each stage of analysis using examples from the Nordic countries.

Prognosis of elderly hospital patients with cerebral thrombosis.

Over 8000 patients with cerebral thrombosis (ICD-8 number 433) hospitalised between 1970 and 1980 were surveyed retrospectively for outcome and additional diseases. The case-fatality rates and long-term prognosis of the patients were strongly affected by age, and the number of patients requiring permanent hospital care rose sharply with increasing age. The case-fatality rates in the different age groups were as follows: under 50 years 6%, 50-64 years 16%, 65-74 years 32%, 75-84 years 48% and over 85 years 66%. The cumulative survival rates at 1 and 5 years were as follows: under 50 years 54 and 46%, 50-64 years and 38%, 65-74 years 60 and 20% and over 75 years 45 and 10%. Clinical manifest coronary heart disease clearly affected the prognosis of patients under 75 years, but the impact diminished with rising age. Although hypertension led to an earlier onset of ischemic stroke, it did not significantly influence the survival prognosis. In patients over 75 years additional diseases, e.g. diabetes, had no significant effect on case-fatality or long-term prognosis underlining the malignant nature of cerebral thrombosis itself.

The incidence and prognosis of cerebrovascular disease in hospital patients in Helsinki, Finland, in the decade 1970-1980.

Over 21,000 hospital episodes due to cerebrovascular disease (CVD, ICD-8 nos. 430-438) were registered in the Helsinki hospitals in 1970-1980. Of those 17,629 were identified as new cases. The age-adjusted incidence of haemorrhagic and thrombotic stroke (430-433) declined during the period 1970-1975 from 221 to 139 cases/100,000 inhabitants, whereafter no further decrease was observed. The decline in incidence was significant in both sexes. Analysis by diagnosis group showed that the decrease was confined to the incidence of haemorrhagic stroke (430-432), whereas the incidence of thromboembolic stroke (433, 434) and transient ischaemic attacks (435) remained virtually unchanged. Survival was mainly determined by patient age and type of CVD. Intracerebral haemorrhage and occlusion of precerebral arteries exhibited the poorest short-term prognosis. About half of the patients hospitalised due to cerebral thrombosis and embolism survived over one year. Long-term prognosis of the major CVD groups was very poor with only 10% of the patients alive after eight years. Transient cerebral ischaemia and subarachnoid haemorrhage had a clearly better prognosis, the survival rates after eight years being 45 and 30%, respectively.

Cerebrovascular disease: declining incidence but increasing hospital utilisation.

A total of 20,680 patients hospitalised in Helsinki during 1970-1980 due to cerebrovascular diseases were found when screening the Finnish National Hospital Discharge Register. The material was categorised according to three-digit ICD-8 diagnosis codes and age, and was analysed for case-fatality, length of stay and discharge status. By identifying all new cases an assessment of the incidence development during the study period was also possible. A fall in the overall age-standardised incidence of cerebrovascular disease was demonstrated, in accordance with disease register studies. The main reason was decline in incidence of haemorrhagic stoke (ICD-8 no. 431) and less well defined types of stroke (436-438). Ischaemic stroke (433), on the other hand, did not decrease in frequency. The diagnostic shift, occurring parallel with a growing mean age of patients, lead to decreasing acute mortality, increasing institutionalisation rates and longer stays in hospital, thus resulting in growing figures of hospital utilisation in spite of the declining incidence.

Combining data on health care utilization and socioeconomic status of a defined population: use of a population oriented health information system for regional planning.

Health services planning on a regional or national level needs information on health care utilization as well as data on the population to be served. Health or hospital information systems usually cover services provision and utilization, and population data for planning purposes must be obtained from other sources. In the health information system presented, hospital performance data are combined with census and socioeconomic data of the population. That makes cautious analysis of reasons for variation in health care utilization within the planning area possible. The HIS is regional, including 11 health care providers, and population based, linking data to municipality (38 in all). The system is described, including its structure, input registration, file content and output formats. An output example is presented. Necessary conditions for use of the HIS in planning activities are that the corresponding health care delivery system is comprehensive, the population served well defined, and that good control of patient flow and user behaviour is achieved. Use is limited by the character of information stored in the HIS: it is registered retrospectively and by routine. In a system covering various hospitals and municipalities, engaging different types of clerical and health care personnel, data reliability is also a critical issue.
