Would primary health care workers give appropriate dietary advice after cholesterol screening?

The purpose of this study was to obtain information on the dietary knowledge of primary health care workers and on their ability to apply this knowledge in practice. A total of 128 primary health care workers (53 general practitioners and 61 nurses) in 12 practices and 14 primary care facilitators were surveyed by questionnaire between December 1987 and June 1988. All of the practices were participating in a project to promote prevention in primary care and offered health checks designed to identify and deal with cardiovascular risk factors. The questionnaire focused on issues related to managing patients with moderate hypercholesterolaemia. The results of the study showed some important gaps in the health workers' knowledge--for example, only 91 understood that dietary intake of polyunsaturated fatty acids as a proportion of total fat intake should be increased in a diet designed to reduce serum lipid concentrations. Appreciable gaps in their ability to give practical and appropriate dietary advice were also identified: 35 gave advice that would have led to the patient losing weight (although his history indicated that he was not overweight), and 27 gave only negative advice, offering no suggestions about substituting healthy foods for unhealthy ones. The demand for primary health care workers to give dietary advice is increasing and is likely to increase further if a national screening programme for hypercholesterolaemia is recommended. The results of this survey point to a need for improved nutritional education and training in dietary counselling for general practitioners, nurses, and primary care facilitators.

The "Help Your Patient Stop" initiative. Evaluation of smoking prevalence and dissemination of WHO/UICC guidelines in UK general practice.

The World Health Organisation and the International Agency against Cancer in 1988 published joint guidelines on smoking cessation for primary health care teams. A booklet entitled Help Your Patient Stop was produced in the United Kingdom as a model for the international dissemination of these guidelines. This booklet was sent to UK general practitioners by post; about 4 weeks later, a random sample of 5000 were asked to complete a postal questionnaire about the booklet and their smoking habits. The response rate was 75%. About half (50.5%) remembered receiving the booklet, 27.7% had read it, and only 8.8% could write down any of the three essential activities in smoking cessation which the booklet was intended to promote and which were printed in bold letters on the inside back cover. Although the booklet itself might be an adequate model for other countries, unless dissemination and marketing of the information it contains can be improved, its achievement will be limited. However, the survey did have one optimistic feature: only 13.5% of general practitioners reported that they smoke; and only a third of those who gave full details of their smoking habit smoke cigarettes.

Three year follow up of patients with raised blood pressure identified at health checks in general practice.

OBJECTIVE: To assess the extent of three year follow up of blood pressure, weight, and smoking habit in patients with raised blood pressure identified at health checks. DESIGN: Retrospective audit of medical and nursing records. SETTING: Three general practices in Oxfordshire. PATIENTS: 386 of 448 patients with raised blood pressure (diastolic greater than or equal to 90 or systolic greater than or equal to 160 mm Hg) identified from 2935 patients aged 35-64 attending health checks in 1982-4. MEASUREMENTS AND MAIN RESULTS: All records of blood pressure, weight, and smoking habit in the medical record were abstracted for three years after the initial health check. All 42 patients with an initial diastolic blood pressure greater than or equal to 105 mm Hg and 316 of 344 patients with an initial pressure of 90-104 mm Hg had at least one further measurement of their blood pressure. Follow up of smoking habit and of weight was less complete with only half of the 100 smokers and 67 of the 87 obese patients (body mass index greater than or equal to 30) having any documented follow up of these risk factors. Annual follow up in the second and third years occurred in 228/297 (76.8%) and 232/320 (72.5%) in patients with blood pressure greater than 95 mm Hg at the beginning of each year. For patients who smoked annual follow up in these years occurred in fewer than a third and for those who were obese in just over half. On the assumption that those not followed up had not changed, at the end of three years the proportion of patients with diastolic blood pressure greater than or equal to 100 mm Hg had fallen from 61 patients (15.8%) to 31 (8.1%); the proportion of smokers had fallen from 103 (26.7%) to 94 (24.4%); and the proportion of obese patients had fallen from 87 (22.5%) to 79 (20.5%). CONCLUSIONS: These changes were modest and in the absence of a control group cannot be attributed necessarily to health checks. Although the standard of follow up was better than in previously reported studies of the management of hypertension, the results emphasise the need to develop formal protocols for dietary and antismoking interventions and to evaluate formally the effectiveness (and cost effectiveness) of health checks.

Management control of open-access radiology: is it possible?

This paper considers management options for limiting general practitioner use of open access radiology - a service for which there is increasing demand which is difficult to meet. In the current climate of cost containment, restriction of general practitioner access to these expensive diagnostic facilities has management appeal. However, it is difficult to justify blanket restriction of access to radiology services as there is no evidence that it would be economically or clinically sensible. An explicit quota system is unlikely to be feasible because of the small number of referrals made by general practitioners and the element of chance which will inevitably enter into the referral process. Managers should examine more closely the manipulation of incentives and costs which are used, often implicitly, to balance the conflicting desires of clinicians and managers. The best management option would appear to involve a re-evaluation of the role of the radiologist to include responsibility for managing the service. This should include assessment of appropriateness of referral by reference to guidelines for investigation and the behaviour of acknowledged good practitioners.

Randomized controlled trial of anti-smoking advice by nurses in general practice.

Practice nurses are playing an increasingly prominent role in preventive care, including the provision of anti-smoking advice during routine health checks. A randomized controlled trial was designed to assess the effectiveness of anti-smoking advice provided by nurses in helping smokers to stop smoking. A total of 14,830 patients aged 16-65 years from 11 general practices completed a brief questionnaire on general health, including smoking status, at surgery attendance. The doctor identified 4330 smokers and randomly allocated 4210 to control or intervention groups. The doctor asked those in the intervention group to make an appointment with the practice nurse for a health check. The attendance rate at the health check was 26%. Smokers were sent follow-up questionnaires at one month and one year, and those who did not respond to two reminders were assumed to have continued to smoke. There was no significant difference in reported cessation between the intervention and control groups at one month or one year. However, there was a significant difference in the proportion of patients who reported giving up within one month and who had not lapsed by one year--0.9% in controls and 3.6% in the intervention group (P less than 0.01). Nevertheless, the effect of the nurse intervention itself may be small as the sustained cessation rate in attenders was only 42.4% higher than in non-attenders. The deception rate in reporting cessation, as measured by urinary cotinine, was of the order of 25%.

Feasibility of contact surveys in general practice.

Surveys to evaluate risk factors for disease in the general population are popular with health authorities for assessing the effectiveness of their preventive measures. A contact survey of the lifestyles of 2000 randomly selected patients aged 25-64 was conducted in five general practices over 18 months; the medical records of the patients selected were tagged, and when the patients first visited the surgery they were given a questionnaire by the receptionists, which they completed in the waiting room. Over the 18 months at least 1400 of these patients visited the practices, of whom 1106 (55%) completed a questionnaire and 20 refused to do so; 896 (81%) completed it within one year. Information on the patients who were not surveyed was obtained by sending the questionnaire by post and by audit of medical records. The population surveyed on contact with the surgeries contained a higher proportion of young women, and possibly a higher proportion of patients from social classes IIIM-V, than the other patients. No important or consistent bias towards unhealthy patients at high risk was identified in the contact survey. A one year contact survey of a random, tagged sample is feasible in estimating the risk factors in a population and may be the method of choice in general practice because of its low cost and adaptability.

Completeness of chronic disease registration in general practice.

The completeness of chronic disease registration in four general practices was assessed by referring to the Hospital Activity Analysis. Overall, just over half (56%) of the 695 patients who had been discharged from hospital with a diagnosis of diabetes, cancer, myocardial infarction, epilepsy, hypertension, or thyroid disease were identified on the practice disease registers. Patients with diabetes were most likely to be identified (72%), and those who had had a myocardial infarct least likely (43%). If the standard of registration is to be improved general practitioners must be convinced of its value. The Hospital Activity Analysis might be used widely to audit and improve practice registers.

Breast self examination and breast cancer stage at diagnosis.

The relationship between breast self examination (BSE) and breast cancer stage at diagnosis was examined in 616 women aged 15-59 years. Differences in tumour characteristics between those not practising BSE and those practising but not taught were small and inconstant. However, women who had both practised and had been taught BSE had more favourable tumours than the non-practising group. The difference was most marked in terms of tumour size and the involvement of axillary nodes. The proportions of women in the non-BSE and taught-BSE groups with each characteristic were respectively: size less than or equal to 2 cm 33% and 45%, T1 clinical stage 27% and 42%, and N0 pathological stage 37% and 50%. This advantage to taught-BSE women persisted after adjustment for the identified confounding factors of age, social class and oral contraceptive use. The likely impact on breast cancer mortality is difficult to assess, although the potential benefit of the lead time gained must not be ignored when assessing the costs and benefits of BSE.

Myocardial infarction and angina pectoris in young women.

The Oxford-Family Planning Association contraceptive study has now followed 17,000 women, predominantly of childbearing age, for a total of more than 200,000 woman-years. The incidence of myocardial infarction and angina in women aged less than 50 years has been low: 0.03/1,000 woman-years at ages 25-34 rising to 0.67/1,000 woman-years at ages 45-49. However, the overall incidence in women who were smokers at entry to the study is more than three times that in women who were non-smokers, the increase in individual risk being proportional to the number of cigarettes smoked. Observations on other risk factors must be treated with caution in view of the small numbers involved: in general, the differences and trends reported are not statistically significant. However, a consistent positive relation is observed between incidence rates and both relative weight and parity after adjustment for age and smoking, while no consistent trend is observed for social class. Ever use of oral contraceptives is associated with a twofold increased risk of myocardial infarction (not statistically significant), but there is no increased risk in current users as was suggested by earlier studies. This may reflect the adoption of lower dose preparations and the positive selection of healthy women for oral contraception.

Measles immunisation rates and the good practice allowance.

The recent discussion document on primary health care proposes that a good practice allowance is paid to general practitioners based in part on the uptake of immunisation by patients. The variation between and the validity of practice immunisation rates for measles as determined by one district health authority's child health computer are assessed. In areas of low population mobility district health authority rates may be sufficiently accurate to base a good practice allowance on but should not be used until the social environment of each practice can also be characterised. In areas of high mobility intermittent surveys may be a preferable method of auditing performance.
