title: Variations in avoidable mortality in relation to health care resources and urbanization level.
abstract: "Avoidable" mortality may be defined as causes of death whose occurrence is closely related to medical intervention. Areas with particular health care delivery problems can be identified through a geographical comparison of these "avoidable deaths." Mortality data for Valencia from 1982 to 1990 were examined to determine whether or not the availability of medical care resources in the area influenced the occurrence of avoidable deaths. We identified variations in mortality from avoidable causes, grouped according to the differences in levels of urbanization and health care resources, in the 537 municipalities of the Valencian community. (In Spain, the municipality is the lowest administrative division.) Linear regression analysis was performed to predict or estimate this relationship. Only in a small number of avoidable causes did the mortality trend for males differ significantly from 0 (p < 0.005) in relation to different levels of urbanization and health care resources. A direct association between these two variables was observed in males with regards to pneumonia, tuberculosis, chronic rheumatic heart disease, and bacterial infection. In females, a relationship between "avoidable" mortality rates and the differences in urbanization and health care resources was found in cervical cancer, pneumonia, abdominal hernias, and cholecystitis. Mortality from asthma and cardiovascular disease (in both males and females) declined faster in urbanized, high income areas than in rural areas. The results clearly demonstrate the considerable mortality risk associated with living in urban areas. On the contrary, we found very little correlation between health service access and mortality.
