Uptake of immunisation in district health authorities in England.

The uptakes of immunisation in the district health authorities in England were studied for the years 1983-5. Multiple regression analysis showed that the factors significantly associated with a low uptake of immunisation were mainly related to social conditions, particularly overcrowding of households and population density. Of the service factors, high proportions of elderly and singlehanded general practitioners and high average list sizes were also associated with a low uptake of immunisation in some of the analyses. The results suggest that the measures outlined in the government's white paper on improving primary health care services are likely to lead to improved uptakes of immunisation. If, however, the uptakes of immunisation are used as a measure of standards of the services provided they should first be adjusted to control for variations in social conditions, and the quality of vaccination data would have to be improved.

Developing primary health care.

Primary health care is best provided by a primary health care team of general practitioners, community nurses, and other staff working together from good premises and looking after the population registered with the practice. It encourages personal and continuing care of patients and good communication among the members of the team. Efforts should be made to foster this model of primary care where possible and also to evaluate its effectiveness. Community services that are not provided by primary care teams should be organised on a defined geographical basis, and the boundaries of these services should coincide as much as possible. Such arrangements would facilitate effective community care and health promotion and can be organised to work well with primary care teams. The patient's right to freedom of choice of a doctor, however, should be retained, as it adds flexibility to the rigidity of fixed geographically based services.

Patterns of physicians' use of medical resources in ambulatory settings.

We studied British general practitioners' use of ambulatory resources to determine whether the quantities of different resources used were related to each other, and whether these quantities were associated with their personal characteristics. Rates of laboratory requests, referrals for specialty opinion, prescriptions, and visits per patient per year were examined for 21 physicians in seven practices over one year. Physicians who more frequently saw their patients referred and prescribed for them more often and ordered more tests, once the number of years they had practiced was taken into account. Doctors who ordered more tests referred their patients more frequently, regardless of how often they saw them. Doctors longer in practice saw and prescribed for their patients more frequently. Resource use was not related to other personal characteristics we studied. Greater frequency of patient-physician contact appears to increase costs not only through use of more professional time but also through greater use of other ambulatory resources. Attention to the use of only one type of resource may result in a distorted picture of how physicians care for their patients and the costs that such care incurs.

Preregistration rotation including general practice at St Mary's Hospital Medical School.

A rotation for the preregistration year which included medicine, surgery, and general practice started at St Mary's Hospital Medical School in August 1981. Initially approved by London University for an experimental period of three years, in 1984 it became an established rotation subject to normal review. Special arrangements were made for clinical work, supervision, prescribing, teaching, and other aspects of the general practice component. Data relating to the general practice consultations of the nine participating house officers show that they obtained wide experience, and their comments on the post itself were generally favourable. The four months spent in general practice were needed to allow time for the house officers to adapt to the new setting but did not seem to have an important effect on their experience in medicine and surgery.

Factors associated with home visiting in an inner London general practice.

We decided to examine the services provided by doctors in an inner London practice for domiciliary care. It was expected that the study would highlight the most relevant questions and variables related to access and uptake of this service; it would thus contribute to the design of an accurate procedure for auditing the pattern of delivery of home care to be conducted in the practice in the future. During the study period, 1976-81, there were 90 500 doctor-patient contacts. For patients up to the age of 10 years the proportion of home visits was 9.2%, falling to 2.2% in the age group 20 to 29; then there is a quasi plateau till the age of 60. After 60 the proportion of home visits doubles in each of the following 10 year age groups, reaching 54% in the over 80s. The proportion of home visits (standardised by age) rises from social class II (8.0%) to social class V (10.0%), but is higher in social class I (11.7%). The proportion of home visits according to distance from the practice rises from 8.2% near the health centre to 9.6% at a distance of 0.25 to 0.50 mile, and drops to 8.8% beyond 0.75 mile. The distance effect is not consistent when the social class dimension is added: social classes I and II have higher proportions of home visits in certain age and distance groups. Single people have the lowest proportion of home visits (6.8%); there are large differences between men and women among widowed (14.1% and 8.6% respectively) and divorced or separated (7.0% and 10.7% respectively) patients. There are important variations in the proportions of home visits made by the doctors in the practice, the trainees carrying out proportionally many more home visits. Data collected in the practice can be used to define specific issues for future audit exercises. Furthermore, sociodemographic characteristics of patients have been shown to be associated with use and access to medical services.

Giving advice about welfare benefits in general practice.

Many people do not receive the full state welfare benefits to which they are entitled. Roughly two thirds of the population consult their general practitioners at least once a year. General practitioners and community nurses are exceptionally well placed to detect those who are suffering genuine financial hardship but they are not well equipped to give advice about the complex system of state social security benifits. Imparting such advice in suitable cases, particularly where the lack of it is detrimental to health, might be regarded as a proper function of general practitioners and health centres. A method of providing such advice in a health centre with the help of a computer is described.

Case history questionnaires in the study of doctors' use of resources. Are they measuring what we want?

A set of 15 self-administered case histories were developed, each consisting of a short case followed by a standard format on which desired tests were checked. After pilot testing the case histories within a group of doctors, the authors selected the ten cases with the highest item-total correlations that also provided a broad clinical spectrum. Using a different group of 19 doctors, test-ordering on the questionnaire was compared with actual test-ordering in clinical practice. Questionnaire test-ordering did not reflect practice behavior; in fact, the relationship tended to be inverse (r = -0.43: P less than 0.10). Adjusting for case-mix variation by including only those practice cases with diagnoses similar to questionnaire cases did not improve its performance (r = -0.50: P less than 0.05). These findings suggest that test-ordering on case history questionnaires may not reflect actual practice behavior. Conclusions about test-ordering behavior and management strategies to alter it should not be based on results from questionnaires that have not been validated against actual practice.

Prescribing--a case for prolonged treatment.

In an earlier study it was shown that general practitioners changed some of their prescribing habits when they were given detailed analyses of their prescriptions every six months for two years and provided with opportunities to discuss the information with participating colleagues. A follow-up study of the same doctors two years later revealed that most of the effects of the intervention had disappeared, though the increase in generic prescribing persisted. It is concluded that a more sustained intervention is needed to bring about more lasting change.

Underprivileged areas: validation and distribution of scores.

Underprivileged areas were identified by weighting several census variables that relate to social conditions, by using weights determined by means of a questionnaire sent to one in 10 of the general practitioners in the United Kingdom. The weighted variables were added (after statistical manipulation) to give a score for each of the 9265 electoral wards in England and Wales. Blank ward maps were sent to general practitioners in five family practitioner committee areas and they were asked to shade the wards according to the degree to which the population increased their workload or the pressure on their services. Maps of these same areas were then prepared by using the calculated scores with the cut off points between the worst, the intermediate, and the best areas as on those used by the general practitioners. The two sets of maps were then compared to determine how well the maps that were based on scores agreed with the general practitioners' maps showing their assessment of the variation of workload in their areas. Overall, 6.3% of the wards differed in shading in any way between the two sets of maps. In the three areas where the general practitioners shaded complete wards and did not report having difficulties with shading only 1.2% of the wards differed. It may be possible to use these "underprivileged area" scores to indicate where problems occur for general practitioners and to extend this work to other primary health care workers.

A comparison of ambulatory test ordering for hypertensive patients in the United States and England.

We compared British and American patterns of ambulatory testing for chronic uncomplicated hypertensive patients by examining test use for 351 American patients cared for by 30 community-based internists in Massachusetts and 511 British patients cared for by 18 general practitioners in Greater London. For each of 13 tests examined, utilization was equal or higher for American patients. Significantly more ECGs, chest roentgenograms, plain roentgenograms (other than chest roentgenograms), blood cell counts, urinalyses, cervical cytological tests, barium enema examinations, and intravenous pyelograms were ordered. Differences ranged from four to 40 times higher in the United States. This investigation documents a marked difference in test use. Further study is needed to determine whether the conservative use of diagnostic services adversely affects patient outcomes or represents a more cost-effective form of care.

Influence of patient characteristics on test ordering in general practice.

Information regarding all consultations was collected in seven general practices for one year. From these data we report on the use of laboratory tests and its association with patient characteristics--including social class, age, sex, and diagnosis--and with which doctor was consulted. Most of the requests were for technically simple tests of low cost. There was a noticeable variation in the use of tests with regard to all patient characteristics. Diagnosis, identity of doctor, age of patient, and social class were each shown by multivariate techniques to be independently related to use of tests. Whereas fewer tests were used per consultation for social classes III-V compared with other social classes, more were used per patient per year for these same groups, reflecting in part the higher consultation rates of social classes III-V. Variation in diagnoses fully accounted for the greater test ordering for women. Nearly two thirds of all tests were ordered for 10% of all patients who consulted and 7% of all registered patients. The results of our analysis suggest that this concentration is determined primarily by those patient characteristics most indicative of medical need and by which doctor is providing care.
