[Does the structure of medical services affect the proportion of death in hospitals? An ecological analysis in the mobility regions of Switzerland?].
OBJECTIVE
With the discussion about measures to reduce over-capacities in the health services in mind, we examined the influence of medical supply structures and services on hospital utilisation directly before death.


METHODS
Based on the specification of the place of dying from the death certificates, we determined the proportions of deaths in hospitals in an ecological study. We analysed deaths of persons above age 65 in each of the 106 mobility regions of Switzerland in the years 1979 to 1980.


RESULTS
The proportion of deaths occurring in hospitals varied between 27% and 81%. Despite missing data regarding stationary and ambulatory care services, more than half of the variance could be explained by means of a multivariate regression analysis. Our results imply an inverse relation between the proportion of deaths in the hospital and the number of consultations provided by primary care physicians, as well as the number of nursing home beds. Further, we observe a direct relation to the number of hospital beds in a region. All indicators are calculated per inhabitant.


CONCLUSIONS
In health care supply planning, such systematic associations should be taken into account. We recommend to analyse regularly interregional differences in supply and outcome of medical performances with the best available data.
