Lifestyle advice in general practice: rates recalled by patients.

OBJECTIVE: To document how often patients with varying cardiovascular risk levels reported receiving lifestyle advice from general practice. DESIGN: Cross sectional descriptive survey by postal questionnaire. SETTING: 5 general practices in Bedfordshire. SUBJECTS: 4941 people aged 35-64 years who had consulted a general practitioner at least once during the 12 months before completing the questionnaire and who subsequently attended for a health check as part of the OXCHECK trial. MAIN OUTCOME MEASURES: Report of having received advice from a general practitioner or practice nurse about smoking, alcohol consumption, exercise, or diet during the 12 months before completing the questionnaire. Cardiovascular risk assessed by a nurse during structured health check. RESULTS: The overall reported rate of advice was 27% for smoking, 4.5% for exercise, 12% for diet, and 3% for alcohol consumption. Those with unhealthy behaviour profile or at increased cardiovascular risk received more advice--for example, 47% of smokers with a history of cardiovascular disease received advice on smoking. Among those at increased risk, men were more likely than women to receive advice about exercise (11% v 4%, p = 0.04) and alcohol consumption (10% v 4%, p = 0.007), while women received more advice about weight (17% v 23%, p < 0.001). The rate of receiving advice was unaffected by age, marital status, or social class. CONCLUSION: The low rate of lifestyle advice reported by patients implies that more preventive advice could be provided in primary care.

The epidemiology of hysterectomy: findings in a large cohort study.

OBJECTIVE: To examine patterns of hysterectomy in the Oxford-Family Planning Association (Oxford-FPA) study in relation to age, parity, social class and calendar period (-1974, 1975-79. 1980-84, 1985-89). DESIGN: The Oxford-FPA study is a large scale prospective study of 17,032 women recruited from 1968-74 and still under observation. SETTING: Seventeen family planning centres throughout England and Scotland. SUBJECTS: At recruitment the 17,032 women were all white, British, married, aged 25-39 and willing to co-operate. In addition, they were using the pill or an intrauterine device or a diaphragm as their method of contraception. MAIN OUTCOME MEASURE: Hysterectomy rates per 1000 woman-years of observation in various subclasses of the data. RESULTS: Up to the end of 1989, 1885 (11.1%) of the 17,032 women in the study were known to have undergone hysterectomy. Fibroids were the most common cause followed closely by menstrual disturbances in the absence of fibroids (hereafter referred to as 'menstrual disturbances'). Social class had a modest influence on hysterectomy rates. Hysterectomy for fibroids, prolapse, endometriosis and 'other reasons' showed little trend with calendar period while hysterectomy for menstrual disturbances and for cancer showed a sharp increase with calendar time especially at ages 30-39. Hysterectomy generally tended to increase with age and showed a strong relation to parity; in particular, hysterectomy for fibroids fell with parity and hysterectomy for menstrual disturbances rose sharply with parity. Using lifetable methods, it was estimated that almost 20% of the women in the study would have had a hysterectomy by age 55. CONCLUSIONS: The results give insights into factors affecting hysterectomy rates. Of particular interest is the modest influence of social class, the strong influence of parity and the rise in rates with calendar time at ages 30-39 for those undergoing hysterectomy for menstrual disturbances or cancer, but since the cohort is not directly representative of the population, some caution is required in extrapolating these findings. The estimated hysterectomy rate of about 20% by age 55 is in line with other similar estimates for the United Kingdom.

Outcomes of referrals to gynaecology outpatient clinics for menstrual problems: an audit of general practice records.

OBJECTIVE: To determine referral rates and intermediate and long-term outcomes for patients consulting for menstrual disorders and referred by their general practitioner to gynaecology outpatient clinics. DESIGN: General practitioners' records of referrals to outpatient clinics and retrospective audit of general practice notes to determine outcomes. SETTING: General practices in the Oxford Regional Health Authority area referring to 19 gynaecology outpatient clinics. SUBJECTS: 205 patients aged 15-59, referred in 1983/4 and follow up in 1988/9. MAIN OUTCOME MEASURES: Immediate outcomes: the initiation by hospital specialists of investigation, treatment or advice. Five year outcomes: general practice consultation rates and symptom prevalence. RESULTS: Of 18,754 index referrals recorded by 33 practices over a period of 6 months, 2513 (13%) went to gynaecology clinics. Menstrual disorders constituted 21% (n = 539) of the gynaecology referrals; there was more than three-fold variation between the practices in referral rates. In the 5 years following the index referral, of the 205 audited patients 167 (81%) had been admitted to hospital, 91 (44%) had had a hysterectomy (including 87 (60%) of the 145 patients referred for menorrhagia), 98 (48%) had dilatation and curettage; 25 (12%) received only drug therapy; and 10 (5%) had no active treatment for these symptoms from either the specialist or the general practitioner. Only 29 (14%) had consulted their general practitioners about menstrual problems in the 12 months preceding the audit. CONCLUSIONS: Guidelines are needed to assist referral decision-making. If audit is to be used to promote good practice these guidelines should consider the patients' anxieties and preferences, as well as the most appropriate use of investigations and treatments.

Outcome of general practitioner referrals to specialist outpatient clinics for back pain.

In 1983-84 general practitioners in the Oxford region kept records of their referrals to outpatient clinics over a period of six months. Five years later in 1988-89 the general practice notes of 182 patients referred for back pain were studied to determine the outcomes of their referral. The actions initiated in the outpatient clinics were compared with the general practitioners' main reason for referral recorded at the time of referral. Of the 182 patients 136 (74.7%) received specialist treatment following the outpatient referral despite the fact that general practitioners had given treatment as the main reason for referral in only 28.6% of cases. Patients' mean consultation rate for back pain declined from 4.2 consultations per annum to 0.9 (P less than 0.001) over the five year period, but there was a small but significant increase in consultations for other problems. Five years after the referral 33.3% of patients were still consulting their general practitioner for back pain. The referral system for patients with chronic back pain could be rationalized to reduce the need for re-referrals and multiple follow-up outpatient consultations. There is a need to improve communications between general practitioners, specialists and patients about the purpose of referral, the likely effects of treatment and the scope for prevention. A survey of the outcome of referrals for common conditions, such as back pain, is a useful first step in the development of referral guidelines.

Prevention in general practice: the views of doctors in the Oxford region.

A postal questionnaire was sent to all 1291 general practitioners in the Oxford region to determine the pattern of preventive care and their beliefs about its effectiveness. Replies were received from 1014 doctors (79%). Doctors' attitudes to their role in prevention and health promotion were very positive and a large majority claimed to discuss health related topics with their patients when indicated. Fewer respondents said they made a point of discussing smoking habits (64%), alcohol intake (26%), diet (12%), or exercise (11%) as a matter of routine with all their adult patients. Most general practitioners said they usually offered simple advice, leaflets, or other aids when they had identified a problem, but few said they would refer these patients to the practice nurse. With the exception of cervical screening (45%), few respondents said they maintained statistics on the distribution of risk factors in their practice population. Despite considerable enthusiasm for their role in preventive health care, before the imposition of the new contact most general practitioners in the Oxford region had not yet embraced the model of prevention which the contract aims to encourage: systematic screening for risk factors and lifestyle advice for all patients.

Patient participation in general practice: who participates?

A postal survey of 4066 men and women aged between 16 and 64 years was carried out in a general practice in Oxfordshire which had a patient participation group, established in 1972. The aim of the survey was to ascertain the knowledge and use of the group among adults aged 16-64 years. The adjusted response rate was 73%. Despite the length of the group's existence only 45% of these patients were aware of it and only 7% had ever attended a meeting. Awareness of the group and sometime attendance were significantly less in men, patients aged between 16 and 29 years, those in social classes 4 and 5, single people and those who smoked. Patients who consulted more than four times per year were more likely to be aware of the group than less frequent consulters. The possible reasons for the unrepresentative nature of the patients attending the group are discussed, together with implications for practice policies and development. Various strategies for making the group more representative are proposed, including advertising within the practice and elsewhere, and the formation of special interest groups for patients with defined medical and social needs, in the hope that this will make the concept of patient participation more relevant.

Relation between general practices' outpatient referral rates and rates of elective admission to hospital.

OBJECTIVE: To examine the variation in rates of admission to hospital among general practices, to determine the relation between referral rates and admission rates, and to assess the extent to which variations in outpatient referral rates might account for the different patterns of admission. DESIGN: A comparison of outpatient referral rates standardised for age and sex and rates of elective admission to hospital for six specialties individually and for all specialties combined. SETTING: 19 General practices in three districts in Oxford Regional Health Authority with a combined practice population of 188 610. MAIN OUTCOME MEASURES: Estimated proportion of outpatient referrals resulting in admission to hospital, extent of variation in referral rates and admission rates among practices, and association between admissions and outpatient referrals. RESULTS: Patients referred to surgical specialties were more likely than those referred to medical specialties to be admitted after an outpatient referral. Overall, the estimated proportion of patients admitted after an outpatient referral was 42%. There were significant differences among the practices in referral rates and admission rates for most of the major specialties. The extent of systematic variance in admission rates (0.048) was similar to that in referral rates (0.037). Referral and admission rates were significantly associated for general surgery; ear, nose, and throat surgery; trauma and orthopaedics; and all specialties combined. For most specialties the practices with higher referral rates also had higher admission rates, casting doubt on the view that these practices were referring more patients unnecessarily. CONCLUSION: Rates of elective admission to hospital vary systematically among general practices. Variations in outpatient referral rates are an important determinant of variations in admission rates.

A total audit of preventive procedures in 45 practices caring for 430,000 patients.

OBJECTIVE: To develop and report the results of a system of audit of computer records in general practice. DESIGN: A retrospective audit of records in practices using the same computer system. Information about recorded preventive procedures was collected by sending the same audit program to each practice on floppy disk. Other characteristics of the practices were determined by postal questionnaire. SETTING: Forty five general practices, widely distributed in England and Wales. SUBJECTS: All 430,901 patients registered with the practices. MAIN OUTCOME MEASURES: Within each practice the percentage of patients in specified age groups for whom certain preventive procedures were recorded as having been carried out. These measures were analysed in relation to practice characteristics. RESULTS: Practice characteristics and recording rates for preventive procedures varied over a wide range. Recording rates were higher in practices with computer terminals on every doctor's desk. Only one practice achieved the new contract target of 90% coverage for recorded primary immunisations, and fewer than two thirds recorded 80% coverage for cervical cytology in the past five years. Practices holding clinics did no better than those without. Smaller partnerships and smaller doctors' list sizes were associated with better performance. CONCLUSIONS: Centrally programmed audit of computerised records is a feasible method of providing data on a regular basis for epidemiological purposes and for performance review. The fact that practices with smaller list sizes had higher levels of recorded preventive care suggests that the trend towards larger lists promoted by the new contract might militate against the intended effect of better preventive care.

Health checks in general practice: another example of inverse care?

OBJECTIVE: To assess attendance at and the characteristics of patients attending health checks for cardiovascular disease offered in a general practice over a period of five years (1984-9). DESIGN: Medical record audit and postal questionnaire survey. SETTING: One general practice in Oxfordshire with a socially diverse population. PARTICIPANTS: 1101 Men and 1110 women aged 35-64 registered with the practice. MAIN OUTCOME MEASURES: Age, sex, marital state, social class, smoking habits, alcohol consumption, and diet. RESULTS: Of the 2211 men and women in the target age group (35-64) in 1989, 1458 (65.9%) had been offered screening and 963 (43.6%) had attended for a health check. Attenders were more likely to be women, aged greater than or equal to 45, married, non-smokers, and of higher social class than patients who did not respond to the invitation. The relative likelihood of non-attendance was 1.24 for smokers, 1.20 for the overweight, 1.16 for heavy drinkers, and 1.28 for those with a less healthy diet, even after adjustment for age, sex, marital state, and social class. CONCLUSIONS: After five years of offering health checks, opportunistically (to men) and in the context of cervical smear tests (to women), less than half of the eligible patients had attended. The likelihood of acceptance of an invitation to attend was inversely related to the patient's cardiovascular risk for all factors measured except age. A coherent strategy to reduce cardiovascular disease depends on more careful targeting of scarce health service resources and more emphasis on public health measures (such as dietary regulation and tobacco taxation). Doctors should be careful not to absolve the government of its public health obligations by substituting unproved preventive interventions aimed at the individual patient.

Organization of care for diabetic patients in general practice: influence on hospital admissions.

The aim of this study was to determine whether there is a relationship between the structure of care for diabetes in general practice and the corresponding admission rates for diabetic patients to hospital. A questionnaire was sent to 350 group or single handed practices in the Oxford region and a retrospective analysis was made of admission rates using hospital activity analysis. Admission rates were adjusted for the age structure of the practices. The degree of organization of care was determined by drawing up a composite score from the answers to the questionnaire and comparing practices with few, average and many facilities. There was a significant trend in the rates of admission across the groups of practices: those with few facilities made 16.2 admissions per 10,000 population over two years, those with average facilities 13.8 admissions, and those with many facilities 14.0 admissions (chi-squared trend = 6.88, 1 df, P less than 0.01). These findings support the hypothesis that organized general practice care reduces the rate of hospital admissions, although there are many other influences on the admission rate from any one practice.

Childhood accidents: a practice survey using general practitioners' records and parental reports.

A survey of accidents in children under 16 years of age from one general practice (list size 6400) was carried out using a postal questionnaire to parents and an audit of medical records. Incidence rates were estimated by audit of medical records as 97% of accidents 'other than minor cuts and bruises' reported by parents had resulted in a medical consultation, and parental reporting was incomplete. For 1986, these rates were 254 per 1000 patients at the age of four years or less, 218 per 1000 at age five to nine years and 238 per 1000 at age 10 to 15 years. However, parental reports of accidents provided better detail of the circumstances of accidents than the medical records: in the latter, the circumstances of accidents were noted in 75% of records and the location in only 40%. Various options for monitoring accidents and near accidents utilizing parental information which could be administered by general practitioners are proposed, including the use of parent-held child health record cards and a 'yellow card' system analogous to that used for reporting adverse drug reactions.

General practitioners' referrals to specialist outpatient clinics. I. Why general practitioners refer patients to specialist outpatient clinics.

There has been much concern about the wide variations in general practitioners' referral rates and the consequent implications for cost and quality of care. This has led to a call to evaluate the appropriateness and effectiveness of referrals. A collaborative audit of referrals to outpatient clinics was conducted by 127 general practitioners in 33 practices in the Oxford region. Records were kept of 18,754 referrals, which included data on diagnoses and reasons for referral. Overall, 6553 (35.4%) of the referrals were for particular treatments or operations and a further 6475 (34.9%) were for specific investigation or diagnosis. Advice on management was the main reason for referral in 2656 (14.3%) cases, and in 1719 (9.3%) cases the general practitioners wanted the consultants to take over managing their patients. Reassurance of either the general practitioner or the patient was recorded as the main reason in only 762 (4.1%) referrals. There seems to be scope for rationalising the referral process. A programme with three stages for evaluating referrals to outpatient clinics is recommended.

General practitioners' referrals to specialist outpatient clinics. II. Locations of specialist outpatient clinics to which general practitioners refer patients.

Although linkage by computer of hospital administration systems across all clinics in a health district is becoming a practical possibility, complete records of general practitioners' referrals to outpatient clinics will be difficult to achieve. Data from a large study of general practitioners' referrals to such clinics were used to calculate the proportion of referrals that crossed district boundaries, the proportion that were made to the private sector; and the number of locations that each practice referred patients to. Of the 17,601 referrals from practices in Oxford Regional Health Authority, 13,857 (78.7%) were made to NHS outpatient clinics within practices' own districts, 1524 (8.7%) to clinics in other districts in the same region, 420 (2.4%) to NHS clinics in other regions, and 1800 (10.2%) to the private sector; but these proportions varied considerably among the practices. The mean number of different NHS hospitals or clinics that each practice referred patients to was 15.8 (range 4-42).

Computer held chronic disease registers in general practice: a validation study.

Lists of patients receiving repeat prescriptions for epilepsy, diabetes, thyroid disease and asthma were compared with chronic disease registers stored on seven practice computers. Diabetes was the most accurately recorded disease: the names of 72% of patients receiving medication for this condition appeared on the relevant disease registers. Agreement between the two data sources was 68% for thyroid disease, 58% for asthma and 49% for epilepsy. The levels of accuracy are not yet high enough for the computerised chronic disease registers to provide an accurate estimate of the prevalence of these conditions, but new system developments suggest a more optimistic outlook for the future.

Do referral rates vary widely between practices and does supply of services affect demand? A study in Milton Keynes and the Oxford region.

Two commonly held beliefs about referral rates were investigated in this study: first that demand for services is determined by supply and secondly that there is wide variation between general practices in their referral rates. All referrals to specialist outpatient clinics were recorded during two 11-week periods by general practitioners in eight practices in the new town of Milton Keynes and in 17 practices elsewhere in the Oxford region. During the first period, only a limited outpatient service was available in the new town; for many specialist services, people had to be referred to hospitals outside the district. Referral rates from Milton Keynes were very similar to those from the rest of the region. By the second period the range of specialist facilities available locally had expanded considerably with the opening of the new district general hospital and during this period there was a statistically significant but rather small increase in referral rates from Milton Keynes. Variation in referral rates between general practices within each geographical group was greater than that between the two groups. Overall, there was about a three-fold variation between general practices in outpatient referral rates which is considerably less than that commonly thought to exist.
