Primary care in Australia.

The Australian health care delivery system is reviewed in this article, with special comment on the implications of the financial components of the system and government concerns regarding costs and over-servicing. General practitioners' perception of their role is not significantly different from the expectation of patients, yet the reality may not match the idealized view. There are problems related to availability and there are developments which seem to pose some threat to the continuing care of patients. New developments have occurred in the way in which practice is organized which give an emphasis to continual availability over 24 hour periods, and these developments pose a challenge to the way in which doctors have organized their practices. Population features--Aborigines, migrants, and the elderly--present significant problems that are not always well met, and the concept of total patient care thereby suffers. The general practitioner's apparent failure to fill the expected role in co-ordination of services is discussed, as is the need for general practitioners to become more actively involved in health education and promotion. The hope for the future lies in the Family Medicine Programme of The Royal Australian College of General Practitioners, which represents a major attempt to provide appropriate vocational training for general practice.

Temperature acclimation and oxygen binding properties of blood of the European eel, Anguilla anguilla.

Temperature acclimation of the European eel, Anguilla anguilla, resulted in red cell GTP/Hb molar ratios of 1.20, 1.77 and 0.80 at 2, 17 and 29 degrees C, respectively. A small increase in blood oxygen capacity was present in 29 degrees C acclimated eels. The CO2 Bohr effect and the shape of the oxygen binding curve (n-Hill) were invariant with both temperature and GTP/Hb. The significant differences in the GTP/Hb ratio corresponded with a strong enhancement of the temperature effect on blood oxygen affinity between 2 and 17 degrees C and a similarly strong compensation between 17 and 29 degrees C. Predicted in vivo P50 values were 3.0, 13.8 and 17.6 mmHg at 2 degrees C, 17 and 29 degrees C, respectively. The adaptational value of these findings are discussed in relation to standard metabolic rates at the various temperatures. A tentative hypothesis is proposed that the present study confirms and expands earlier work and supports the contention that adjustments in blood oxygen affinity of thermally acclimated teleosts serve to provide them with an unloading O2 tension for diffusion closely matching the standard oxygen requirements at the various temperatures.

Seasonal variations in hematocrit, red cell hemoglobin and nucleoside triphosphate concentrations, in the European eel Anguilla anguilla.

Eels acclimatized in nature show a significant annual variation in erythrocytic guanosine triphosphate (GTP) concentration, temperature range 0.5-17 degrees C. A similar but smaller annual variation is also present in eels acclimated in the laboratory at constant temperature, 17 degrees C. Hematocrit and blood oxygen capacity showed no seasonal variation. Natural minimal and maximal red cell GTP concentrations were found at the end of the dormancy period (March) and in the late summer, respectively. Furthermore, a chronological connection of the erythrocytic GTP values versus ambient temperature, in the natural environment, demonstrates a hysteresis. This allows for a prediction of a slowly progressing enhancement of the temperature effect on Hb-O2 binding throughout autumn, whereas a relatively fast and pronounced enhancement predictably takes place in spring (April-May) coincident with the "awakening" of the eels.

Patients attending an accident and emergency department for primary medical care.

An increasing number of people seek primary care at casualty or accident and emergency departments of hospitals. A questionnaire was completed by patients attending for primary care at an Australian hospital. The study aimed to determine why patients chose the hospital for their medical care, whether patients triaged to the Primary Care Unit differed from patients triaged to the Casualty section of the Accident and Emergency Department, and whether the characteristics of patients attending at daytime differed from those attending out of hours. There were no significant differences between daytime and out-of-hours attenders according to sex or whether born in Australia or not. More children presented at night or at the weekend; more older people presented by day. There were more single, divorced, separated and widowed patients among the daytime attenders. Daytime attenders had significantly lower incomes than out-of-hours attenders, were less likely to have a local general practitioner or full health insurance: most had a health care card and cost may have been a factor in their attendance. Out-of-hours attenders who had a local general practitioner appeared to be unaware of any deputizing services or had rejected them in favour of the hospital service.

The elderly isolate.

Isolates do not differ from other elderly people in respect of their medical illnesses. They do differ in their ability to cope. When well, they cope better than do non-isolates. However, when incapacitated by sickness, they require supportive help services more often and if these are lacking, are more likely to be admitted to a nursing home. Loneliness, alcohol dependence and depression are more often problems of the isolate.

The assessment of need for support services as seen by general practitioners and a geriatric population.

The majority of doctors accepted the need for involvement in the management of patients with behavioural, family and welfare type problems. The health team concept was seen as desirable by a majority of respondents, though they appeared to feel that it made no great difference if the team members functioned from a health centre or were located in different sites. They were not so well informed as to the availability of supportive welfare services as they were of medical services. Of the elderly people interviewed, most had received medical care in the previous two months, and chiropody was the commonest supportive service used. About half were assessed as having at least one disability affecting their functional capacity, and a significant number were thought to be receiving inadequate care. There was an obvious need for home help services, which were in limited supply.

A department of personal and family medicine.

There has been increasing, worldwide dissatisfaction with the relevance of medical education to health care. Recently, a special task group set up by The Royal Australian College of General Practitioners made a study of how a department of personal and family medicine could participate in the education of the medical student. The task was to present first steps in a research and development programme for education of health personnel to work in and near the family setting. Two academics, two nurse educators, two general practitioners, one specialist surgeon involved in medical education and a fifth-year medical student made up the group. It worked at the task during a six-day live-in teaching and leadership seminar at Leura, New South Wales, in February, 1973.
