Trends in general practitioner distribution from 1984 to 1989.

An analysis of the distribution of general practitioners by electorates during the six years 1984 to 1989 showed that the maldistribution of practitioners in Australia has worsened despite significant increases (26%) in total general practitioner numbers. One in five rural electorates had worse population-to-general-practitioner ratios in 1989 than in 1984. The changes in distribution of general practitioners ran counter to the changes in distribution of the population over the period studied. In 1984, the 38.7% of the population living in rural Australia was served by 33% of the nation's general practitioners. By 1989, more of the population (39.8%) lived in rural areas but they were served by a smaller proportion (32%) of the general practitioner workforce. It is clear that many urban electorates have fewer people per general practitioner than the most generous ideal ratios, while most rural electorates have more people per general practitioner than the least generous.

General practitioner services under Medicare.

This paper examines how general practitioner numbers, bulk-billing rates and sociodemographic variables determined usage of general practitioners and services delivered over the period from 1984 to 1990. A 10 per cent sample of patient services, maintained by the Commonwealth Department of Health, Housing and Community Services, provided the data. Data were aggregated into 148 electorates. Separate regression analyses examined the determinants of the proportion of the population attending a general practitioner and of the number of general practitioner services delivered per patient. Determinants of the growth of these levels over the seven-year period were also examined. Region (metropolitan versus rural), age structure and general practitioner supply were significant factors in these analyses. Bulk-billing rates explained nine per cent of variance in patient numbers and 22 per cent of variance in service numbers after sociodemographic variables and general practitioner supply had been taken into account. The analyses suggest that bulk-billing and general practitioner supply influence the behaviour of patients and doctors and that the effect of bulk-billing is independent of indices of medical need. This implies that bulk-billing may increase service rates and this increase is not clearly directed to improving access to medically necessary services. Because no measures of treatment outcome are available. it is not possible to decide whether the effects observed represent an improvement in health care or are better seen as overuse by patients and demand inducement by practitioners.

Cell surface glycoconjugates in intercellular and cell-substratum interactions.

Progress in understanding the role of the carbohydrate moieties of cell surface adhesion molecules is evaluated. Functional roles of the oligosaccharides of extracellular matrix glycoproteins are also considered. Selected examples of glycoconjugate participation in cell-cell and cell-substratum interactions are presented with emphasis on systems in which structures of functionally important glycosyl moieties of glycoproteins and glycolipids have been determined. Where available, cases of altered cell adhesive behavior attributable to transformation-associated alterations in glycosylation of adhesion molecules are cited.
