Hay Fever Treatment in General Practice: A Randomised Controlled Trial Comparing Standardised Western Acupuncture with Sham Acupuncture

The effect of standardised, Western acupuncture on hay fever symptoms was investigated in a randomised, controlled, single-blind trial in comparison with “sham” acupuncture. Three general practices, in Oxfordshire (rural), Lincolnshire (semi-rural), and Peterborough (urban), recruited 102 patients aged 16 or over with long-standing, moderate or severe hay fever symptoms that had required continuous therapy for at least one month of the year for three or more consecutive years.

The patients were asked to keep a diary to record: the amount of medication used daily; a daily symptom score (using a ten-point scale), from which was derived a weekly remission of symptoms score; and their assessment of the effect of acupuncture on the hay fever symptoms. Symptom scores and use of medication were similar in the two groups. In the four-week period following each patient's first treatment, remission of symptoms was reported by 39.0% in the active treatment group and 45.2% in the sham group; mean weekly symptom scores were 18.4 and 17.6 respectively; and mean units of medication used were 4.1 and 5.0 respectively. Sixteen out of 43 patients in the active treatment group and 14 out of 43 in the sham group felt that the acupuncture had had an excellent or very good effect on their hay fever. The treatments were simple, safe, reproducible and perceived as equally effective. Whether this represented an acupuncture effect, a placebo effect, or natural variation in a fluctuating condition, is not clear.

Self-monitoring of blood glucose changed non-insulin-treated Type 2 diabetes patients' beliefs about diabetes and self-monitoring in a randomized trial

AIMS

To determine whether differences in beliefs about diabetes and its treatment resulted from different intensities of self-monitoring of blood glucose (SMBG) in non-insulin treated patients with Type 2 diabetes in the Diabetes Glycaemic Education and Monitoring (DiGEM) trial.

METHODS

Patients (n = 453) were randomized to usual care, less-intensive SMBG and more intensive SMBG. Beliefs about diabetes were measured with a standard questionnaire (the revised Illness Perceptions Questionnaire; IPQ-R). Changes in beliefs were analysed using analysis of covariance (ancova) with adjustment for baseline values. Mediation analyses assessed whether differences in behavioural outcomes between groups could be attributed to differences in beliefs.

RESULTS

Completed questionnaires were returned by 339 patients (74.8%). Respondents were mean (+/- sd) age 65.9 +/- 10 years and with diabetes duration of 4.8 +/- 4.7 years (median 36, range 1-384 months). Concerns about the consequences of diabetes increased in both self-monitoring groups, relative to control subjects [P = 0.004; Cohen's d standardized effect size = 0.19 less intensive and d = 0.36 more intensive monitoring]. No other beliefs about diabetes differed between groups. Beliefs about the importance of self-testing increased in both self-monitoring groups relative to the usual-care group (P < 0.001; d = 0.57 less intensive and d = 0.63 more intensive monitoring). Changes in psychological well-being did not differ between groups, but control patients reported greater increases in general (P = 0.014) and specific (P < 0.001) dietary adherence than did patients in the self-monitoring groups. These outcomes were not mediated by intervention-related changes in beliefs.

CONCLUSIONS

Despite changes in some beliefs about diabetes differing between groups there were no corresponding changes in self-reported health behaviours. This suggests that changes in illness beliefs resulting from SMBG do not cause changes in diabetes-related health behaviours.

Why is there a modifying effect of gestational age on risk factors for cerebral palsy?

OBJECTIVE

To investigate risk factors for cerebral palsy in relation to gestational age.

DESIGN

Three case-control studies within a geographically defined cohort.

SETTING

The former Oxfordshire Health Authority.

PARTICIPANTS

A total of 235 singleton children with cerebral palsy not of postnatal origin, born between 1984 and 1993, identified from the Oxford Register of Early Childhood Impairment; 646 controls matched for gestation in three bands: <or=32 weeks; 33-36 weeks; >or=37 weeks.

RESULTS

Markers of intrapartum hypoxia and infection were associated with an increased risk of cerebral palsy in term and preterm infants. The odds ratio (OR) for hypoxia was 12.2 (95% confidence interval 1.2 to 119) at <or=32 weeks and 146 (7.4 to 3651) at >or=37 weeks. Corresponding ORs for neonatal sepsis were 3.1 (1.8 to 5.4) and 10.6 (2.1 to 51.9). In contrast, pre-eclampsia carried an increased risk of cerebral palsy at >or=37 weeks (OR 5.1 (2.2 to 12.0)) but a decreased risk at <or=32 weeks (OR 0.4 (0.2 to 1.0)). However, all infants <or=32 weeks with maternal pre-eclampsia were delivered electively, and their risk of cerebral palsy was no lower than that of other electively delivered <or=32 week infants (OR 0.9 (0.3 to 2.7)). Nearly 60% of <or=32 week controls were delivered after spontaneous preterm labour, itself an abnormal event.

CONCLUSION

Inflammatory processes, including pre-eclampsia, are important in the aetiology of cerebral palsy. The apparent reduced risk of cerebral palsy associated with pre-eclampsia in very preterm infants is driven by the characteristics of the gestation matched control group. Use of the term "protective" in this context should be abandoned.

The dopamine D2 receptor C32806T polymorphism (DRD2 Taq1A RFLP) exhibits no association with smoking behaviour in a healthy UK population

A single nucleotide polymorphism (SNP) in the Taq1A site near the DRD2 gene has been associated in several studies with smoking behaviour. We genotyped 732 current smokers (241 low, one to nine cigarettes a day, 250 mid, 10-19 cigarettes, 241 high, 20+cigarettes) and 243 never-smokers at this site (C32806T), to test for effects on smoking initiation and amount of tobacco consumed. No significant association between minor allele frequency and smoking status was detected. Multiple regression analysis including DRD2 genotype, sex, age and alcohol consumption as predictors showed that level of cigarette consumption was associated with sex (p=0.003) and age (p=0.002) but not with alcohol consumption (p=0.25) or DRD2 genotype (p=0.76).

Parents measuring pulses; an observational study

Parent reported pulse rates could provide important information on a child's clinical condition. The agreement between the parent's measurement of their child's pulse and a pulse oximeter was assessed following a brief educational intervention. Parents can be taught to measure the pulse of school age children, but have difficulty with preschool children.

Health and school performance of teenagers born before 29 weeks gestation

OBJECTIVE

To ascertain the health and school performance of teenagers born before 29 weeks gestation (extremely low gestational age (ELGA)) and to compare those in mainstream school with classroom controls.

METHODS

Three geographically defined cohorts of babies born in 1983 and 1984 were traced at the age of 15-16 years. Their health, abilities, and educational performance were ascertained using postal questionnaires to the teenagers themselves, their parents, their general practitioners, and the teachers of those in mainstream school. Identical questionnaires were sent to classroom controls.

RESULTS

Of the 218 teenagers surviving to the age of 16 years, information was obtained on 179. Of these, 29 were in special schools and 150 in mainstream school, 10 of whom had severe motor or sensory impairment. Using the Child Health Questionnaire, parents of teenagers in mainstream school reported a higher incidence of problems than controls in physical functioning (difference in mean scores 9.0 (95% confidence interval (CI) 4.9 to 13.1)) and family life (difference in mean scores for family cohesion 7.0 (95% CI 1.6 to 12.4)). In all areas of learning, teachers rated the ability of the ELGA teenagers in mainstream school lower than the control group. Parents of teenagers in special schools reported a higher rate of problems in most areas.

CONCLUSIONS

One in six ELGA survivors at age 16 years have severe disabilities and are in special schools. Most ELGA survivors are in mainstream school and are coping well as they enter adult life, although some will continue to need additional health, educational, and social services.

Effects of fruit and vegetable consumption on plasma antioxidant concentrations and blood pressure: a randomised controlled trial

BACKGROUND

High dietary intakes of fruit and vegetables are associated with reduced risks of cancer and cardiovascular disease. Short-term intensive dietary interventions in selected populations increase fruit and vegetable intake, raise plasma antioxidant concentrations, and lower blood pressure, but long-term effects of interventions in the general population are not certain. We assessed the effect of an intervention to increase fruit and vegetable consumption on plasma concentrations of antioxidant vitamins, daily fruit and vegetable intake, and blood pressure.

METHODS

We undertook a 6-month, randomised, controlled trial of a brief negotiation method to encourage an increase in consumption of fruit and vegetables to at least five daily portions. We included 690 healthy participants aged 25-64 years recruited from a primary-care health centre.

FINDINGS

Plasma concentrations of alpha-carotene, beta-carotene, lutein, beta-cryptoxanthin, and ascorbic acid increased by more in the intervention group than in controls (significance of between-group differences ranged from p=0.032 to 0.0002). Groups did not differ for changes in lycopene, retinol, alpha-tocopherol, gamma-tocopherol, or total cholesterol concentrations. Self-reported fruit and vegetable intake increased by a mean 1.4 (SD 1.7) portions in the intervention group and by 0.1 (1.3) portion in the control group (between-group difference=1.4, 95% CI 1.2-1.6; p<0.0001). Systolic blood pressure fell more in the intervention group than in controls (difference=4.0 mm Hg, 2.0-6.0; p<0.0001), as did diastolic blood pressure (1.5 mm Hg, 0.2-2.7; p=0.02).

INTERPRETATION

The effects of the intervention on fruit and vegetable consumption, plasma antioxidants, and blood pressure would be expected to reduce cardiovascular disease in the general population.

Antibacterial prescribing and antibacterial resistance in English general practice: cross sectional study

OBJECTIVE

To quantify the relation between community based antibacterial prescribing and antibacterial resistance in community acquired disease.

DESIGN

Cross sectional study of antibacterial prescribing and antibacterial resistance of routine isolates within individual practices and primary care groups.

SETTING

405 general practices (38 groups) in south west and north west England.

MAIN OUTCOME MEASURES

Correlation between antibacterial prescribing and resistance for urinary coliforms and Streptococcus pneumoniae.

RESULTS

Antibacterial resistance in urinary coliform isolates is common but the correlation with prescribing rates was relatively low for individual practices (ampicillin and amoxicillin r(s)=0.20, P=0.001; trimethoprim r(s)=0.24, P=0.0001) and primary care groups (ampicillin and amoxicillin r(s)=0.44, P=0.05; trimethoprim r(s)=0.31, P=0.09). Regression coefficients were also low; a practice prescribing 20% less ampicillin and amoxicillin than average would have about 1% fewer resistant isolates (0.94/100; 95% confidence interval 0.02 to 1.85). Resistance of S pneumoniae to both penicillin and erythromycin remains uncommon, and no clear relation with prescribing was found.

CONCLUSIONS

Routine microbiological isolates should not be used for surveillance of antibacterial resistance in the community or for monitoring the outcome of any change in antibacterial prescribing by general practitioners. Trying to reduce the overall level of antibiotic prescribing in UK general practice may not be the most effective strategy for reducing resistance in the community.

Evaluation of the impact of two educational interventions on GP management of familial breast/ovarian cancer cases: a cluster randomised controlled trial

BACKGROUND

It has been suggested that primary care should become more involved in providing genetic services, such as basic risk assessment, to enable patients with a moderate/high risk to be referred and those with a low risk to receive reassurance and advice from their general practitioner (GP). However, GPs currently lack knowledge and confidence in this area.

AIM

To investigate the effect of an in-practice educational session and information pack on GP management of familial breast/ovarian cancer cases.

DESIGN OF STUDY

Cluster randomised controlled trial.

SETTING

GP principals in 170 practices in Oxfordshire and Northamptonshire. Of the 688 GPs, 426 (62%) participated.

METHOD

Practices were randomised either to Group A (receiving an inpractice educational session plus information pack), Group B (receiving an information pack alone), or Group C (receiving neither an educational session nor a pack). The main study outcome was the proportion of GPs making the correct referral decision on at least five out of six family history vignettes. A secondary outcome was GPs' reported confidence in managing patients with a family history of breast/ovarian cancer, measured by a score that was generated by combining responses to four questions.

RESULTS

There was a 40% (95% CI = 30-50%, P < 0.001) improvement in the proportion of GPs who made the correct referral decision on at least five out of the six vignettes in Group A (111/140 [79%]) compared with Group C (controls) (63/162 [39%]), and a 42% (95% CI = 31-52%, P < 0.001) improvement in Group B (100/124 [81%]) compared with the control group. There was a trend in reported confidence in the management of individuals with a family history of breast/ovarian cancer from a mean confidence score of 2.3 in Group A to 2.0 in Group B and 1.5 in Group C (P < 0.001).

CONCLUSION

Providing GPs with an information pack significantly improved referral decisions regarding patients with a family history of breast/ovarian cancer. Although extremely well received, an in-house educational session produced no additional improvements. There were, however, greater levels of reported confidence in the group who received the educational session in addition to the information pack.

Referral of patients with a family history of breast/ovarian cancer--GPs' knowledge and expectations

BACKGROUND

Primary care is expected to play a significant role in the management of patients with genetic problems. Currently, this particularly involves patients with a family history of cancer. If GPs are to exercise their gatekeeper role efficiently in this area, they must be able to evaluate genetic risk and make appropriate referral decisions.

OBJECTIVES

The aim of this study was to examine GPs' ability to assess risk and to make appropriate referral decisions for women with a family history of breast/ovarian cancer, and to determine their expectations of a referral to secondary care.

METHOD

A questionnaire survey was carried out of the 282 GP principals working within Bedfordshire Health Authority. GPs were asked to make decisions for six simulated cases of women presenting with a family history of breast or ovarian cancer.

RESULTS

A total of 164 (58%) GPs returned completed questionnaires. Across the six family histories, the percentage of GPs making an appropriate risk assessment ranged from 21% [95% confidence interval (CI) 14-27%] to 63% (95% CI 56-71%), and an appropriate referral decision ranged from 40% (95% CI 32-48%) to 80% (95% CI 73-86%). Regardless of their accuracy of risk assessment, most GPs were consistent in deciding not to refer low risk women and to refer moderate and high risk women (range 71-85% of GPs for the six family histories). Only 43 (26%, 95% CI 20-33%) of GPs knew the three most important criteria for risk assessment.

CONCLUSIONS

GPs require more help and education to enable them to perform their gatekeeper role satisfactorily when assessing patients with a family history of breast/ovarian cancer.

Cluster randomised controlled trial to compare three methods of promoting secondary prevention of coronary heart disease in primary care

OBJECTIVE

To assess the effectiveness of three different methods of promoting secondary prevention of coronary heart disease in primary care.

DESIGN

Pragmatic, unblinded, cluster randomised controlled trial.

SETTING

Warwickshire.

SUBJECTS

21 general practices received intervention; outcome measured in 1906 patients aged 55-75 years with established coronary heart disease.

INTERVENTIONS

Audit of notes with summary feedback to primary health care team (audit group); assistance with setting up a disease register and systematic recall of patients to general practitioner (GP recall group); assistance with setting up a disease register and systematic recall of patients to a nurse led clinic (nurse recall group).

MAIN OUTCOME MEASURES

At 18 months' follow up: adequate assessment (defined) of 3 risk factors (blood pressure, cholesterol, and smoking status); prescribing of hypotensive agents, lipid lowering drugs, and antiplatelet drugs; blood pressure, serum cholesterol level, and plasma cotinine levels.

RESULTS

Adequate assessment of all 3 risk factors was much more common in the nurse and GP recall groups (85%, 76%) than the audit group (52%). The advantage in the nurse recall compared with the audit group was 33% (95% confidence interval 19% to 46%); in the GP recall group compared with the audit group 23% (10% to 36%), and in the nurse recall group compared with the GP recall group 9% (-3% to 22%). However, these differences in assessment were not reflected in clinical outcomes. Mean blood pressure (148/80, 147/81, 148/81 mm Hg), total cholesterol (5.4, 5.5, 5.5 mmol/l), and cotinine levels (% probable smokers 17%, 16%, 19%) varied little between the nurse recall, GP recall, and audit groups respectively, as did prescribing of hypotensive and lipid lowering agents. Prescribing of antiplatelet drugs was higher in the nurse recall group (85%) than the GP recall or audit groups (80%, 74%). After adjustment for baseline levels, the advantage in the nurse recall group compared with the audit group was 10% (3% to 17%), in the nurse recall group compared with the GP recall group 8% (1% to 15%) and in the GP recall group compared with the audit group 2% (-6% to 10%).

CONCLUSIONS

Setting up a register and recall system improved patient assessment at 18 months' follow up but was not consistently better than audit alone in improving treatment or risk factor levels. Understanding the reasons for this is the key next step in improving the quality of care of patients with coronary heart disease.

An assessment of morbidity registers for coronary heart disease in primary care. ASSIST (ASSessment of Implementation STrategy) trial collaborative group

BACKGROUND

Organised care delivered systematically to all patients with established coronary heart disease (CHD) can reduce their risk factors and improve their quality of life. Therefore, identifying all patients with established CHD in a general practice population is an important first step for delivering this effective healthcare. However, there is little information on how registers are compiled, the factors that predict inclusion on the register or the relationship between registration and level of care provided.

AIM

To assess the completeness of morbidity registers for CHD in primary care, the factors that predict inclusion on the register, and the relationship between registration and level of care provided.

METHOD

Observational study at baseline of 1979 patients aged 55 to 75 years with established CHD in 18 general practices recruited for a cluster randomised controlled trial.

RESULTS

The proportion of CHD patients correctly identified on practice morbidity registers varied from 29.3% to 100%. Four factors were significantly and independently associated with being on a register: a relevant surgery contact since diagnosis (OR = 2.1, 95% CI = 1.6%-2.9%); a relevant repeat prescription since diagnosis (OR = 1.6, 95% CI = 1.1%-2.3%); a diagnosis of myocardial infarction (OR = 1.5, 95% CI = 1.2%-1.9%); and a revascularisation procedure (OR = 1.5, 95% CI = 1.1%-2.0%). Inclusion on a register was strongly associated with being adequately assessed (i.e. assessed for smoking status, blood pressure, and cholesterol) (OR = 1.8, 95% CI = 1.3%-2.3%) and with treatment with aspirin or a lipid-lowering agent (OR = 1.4 for each agent).

CONCLUSION

A wide variation in registration levels between practices exists. There is evidence that practices using multiple methods of case detection achieve higher levels of registration. The association between registration and better care does not prove causality but an effective call-recall system is impossible without complete registration.

Association between polymorphisms in dopamine metabolic enzymes and tobacco consumption in smokers

Central dopaminergic reward pathways give rise to dependence and are activated by nicotine. Allelic variants in genes involved in dopamine metabolism may therefore influence the amount of tobacco consumed by smokers. We developed assays for polymorphisms in dopamine beta-hydroxylase (DBH), monoamine oxidase (MAO) and catechol O-methyl transferase (COMT) using the polymerase chain reaction with sequence specific primers (PCR-SSP). We then typed 225 cigarette smokers to assess whether genotype was related to the number of cigarettes smoked a day. Smokers with DBH 1368 GG genotype smoked fewer cigarettes than those with GA/AA [mean difference -2.9 cigarettes, 95% confidence interval (CI) -5.5, -0.4; P = 0.022]. The effect reached statistical significance in women (-3.8, 95% CI -6.4, -1.0, P = 0.007) but not in men (-1.5, 95% CI -6.0, 3.0, P = 0.498). Overall, the effect was greater when analysis was confined to Caucasians (-3.8, 95% CI -6.6, -1.1, P = 0.007). Smokers with MAO-A 1460 TT/TO smoked more cigarettes than those with CC/CT/CO (2.9, 95% CI 0.6, 5.1, P = 0.013). Within each sex group, the trend was similar but not statistically significant (difference for men 2.9, 95% CI -1.0, 6.7; for women 2.0, 95% CI -0.7, 4.8). The effect of the allele was greater in smokers with a high body mass index (> 26) (difference 5.1, 95% CI 1.4, 8.8, P = 0.008). More heavy smokers (> 20 a day) had the DBH 1368A allele when compared to light smokers (< 10 a day). (Relative risk 2.3, 95% CI 1.1, 5.0, P = 0.024.) The trend for increasing prevalence of the DBH A allele in heavy smokers was greater when analysis was restricted to Caucasians (relative risk 3.2, 95% CI 1.3, 8.2, P = 0.004). Conversely, heavy smokers were less likely to have the MAO-A 1460C allele (relative risk 0.3, 95% CI 0.1, 0.7, P = 0.012). Variations in DBH and MAO predict whether a person is a heavy smoker and how many cigarettes they consume. Our results support the view that these enzymes help to determine a smoker's requirement for nicotine and may explain why some people are predisposed to tobacco addiction and why some find it very difficult to stop smoking. This finding has important implications for smoking prevention and offers potential for developing patient-specific therapy for smoking cessation.

Computer support for interpreting family histories of breast and ovarian cancer in primary care: comparative study with simulated cases

OBJECTIVES

To evaluate the potential effect of computer support on general practitioners' management of familial breast and ovarian cancer, and to compare the effectiveness of two different types of computer program.

DESIGN

Crossover experiment with balanced block design.

PARTICIPANTS

Of a random sample of 100 general practitioners from Buckinghamshire who were invited, 41 agreed to participate. From these, 36 were selected for a fully balanced study.

INTERVENTIONS

Doctors managed 18 simulated cases: 6 with computerised decision support system Risk Assessment in Genetics (RAGs), 6 with Cyrillic (an established pedigree drawing program designed for clinical geneticists), and 6 with pen and paper.

MAIN OUTCOME MEASURES

Number of appropriate management decisions made (maximum 6), mean time taken to reach a decision, number of pedigrees accurately drawn (maximum 6). Secondary measures were method of support preferred for particular aspects of managing family histories of cancer; importance of specific information on cancer genetics that might be provided by an "ideal computer program."

RESULTS

RAGs resulted in significantly more appropriate management decisions (median 6) than either Cyrillic (median 3) or pen and paper (median 3); median difference between RAGs and Cyrillic 2.5 (95% confidence interval 2.0 to 3.0; P<0.0001). RAGs also resulted in significantly more accurate pedigrees (median 5) than both Cyrillic (median 3.5) and pen and paper (median 2); median difference between RAGs and Cyrillic 1.5 (1.0 to 2.0; P<0.0001). The time taken to use RAGs (median 178 seconds) was 51 seconds longer per case (95% confidence interval 36 to 65; P<0.0001) than pen and paper (median 124 seconds) but was less than Cyrillic (median 203 seconds; difference 23. (5 to 43; P=0.02)). 33 doctors (92% (78% to 98%)) preferred using RAGs overall. The most important elements of an "ideal computer program" for genetic advice in primary care were referral advice, the capacity to create pedigrees, and provision of evidence and explanations to support advice.

CONCLUSIONS

RAGs could enable general practitioners to be more effective gatekeepers to genetics services, empowering them to reassure the majority of patients with a family history of breast and ovarian cancer who are not at increased genetic risk.

Patients with cancer holding their own records: a randomised controlled trial

BACKGROUND

The burden of cancer care in general practice is increasing. Patient-held records may facilitate effective, coordinated care, but no randomised controlled trials of their use in cancer care have been conducted, and concerns about possible negative effects remain.

AIM

To evaluate the use of a supplementary patient-held record in cancer care.

METHOD

Six hundred and fifty radiotherapy outpatients with any form of cancer were randomised either to hold a supplementary record or to receive normal care. It was explained to record holders that the supplementary record was intended to improve communication with health professionals and act as an aide memoire. After three months, patients' satisfaction with communication and with participation in their own care were assessed. Global health status, emotional functioning, and cognitive functioning were measured using the European Organization for Research and Treatment of Cancer QLQ-C30 questionnaire.

RESULTS

There were no significant differences between groups in any of the outcome measures. Patients in both groups expressed a high level of satisfaction with communication and participation in their care. Mean (SD) scores in the intervention and control groups were: global health status, 66.8 (24.2) and 65.3 (23.7); emotional functioning, 75.0 (24.6) and 77.4 (22.8); cognitive functioning, 84.5 (21.0) and 84.0 (21.3).

CONCLUSION

A supplementary patient-held record for radiotherapy outpatients appears to have no effect on satisfaction with communication, participation in care, or quality of life.

Nutrient intakes during pregnancy: the influence of smoking status and age

STUDY OBJECTIVE

To examine the relation of antioxidant and other nutrient intakes in pregnancy to smoking and sociodemographic variables.

DESIGN

Cohort study.

SETTING

St Mary's Maternity Hospital, Portsmouth.

PARTICIPANTS

Pregnant nulliparous women, with no existing complications of pregnancy, were recruited from antenatal booking clinics. A total of 774 women completed seven day food diaries, and supplied detailed data on their use of nutrient supplements.

MAIN RESULTS

Smokers had lower intakes of most micronutrients. After adjustment for the confounding effects of maternal age, height, and education, only vitamin C and carotenoid intakes remained significantly depressed. Age was strongly and significantly associated with the intake of most nutrients, including antioxidants, and this association was independent of other maternal factors. Antioxidant intake was therefore lowest in young women who smoked: for example smokers under 24 years had a mean vitamin C intake of 57 mg (SD 35) compared with 106 mg (SD 52) for non-smokers aged 28 and over (difference 49 mg, 95% CI 39, 59). The corresponding intakes of carotenoid equivalents were 1335 micrograms (SD 982) and 2093 micrograms (SD 1283) (difference 758 micrograms, 95% CI 496, 1020).

CONCLUSIONS

The study has identified, for the first time, young pregnant women as a group at particular risk of low micronutrient intake. The health implications of poor nutrition now need to be evaluated, particularly for those women who smoke.

Comparison of breast cancer patient satisfaction with follow-up in primary care versus specialist care: results from a randomized controlled trial

BACKGROUND

Routine follow-up of breast cancer patients in specialist clinics is standard practice in most countries. Follow-up involves regularly scheduled breast cancer check-ups during the disease-free period. The aims of follow-up are to detect breast cancer recurrence and to provide psychosocial support to the patient; however, little is known about patients' views on breast cancer follow-up.

AIM

To assess the effect on patient satisfaction of transferring primary responsibility for follow-up of women with breast cancer in remission from hospital outpatient clinics to general practice.

METHOD

Randomized controlled trial with 18 months' follow-up in which women received routine follow-up either in hospital outpatient clinics or from their own general practitioner. Two hundred and ninety-six women with breast cancer in remission receiving regular follow-up care at two district general hospitals in England were included in the study. Patient satisfaction was measured by means of a self-administered questionnaire supplied three times during the 18-month study period.

RESULTS

The general practice group selected responses indicating greater satisfaction than did the hospital group on virtually every question. Furthermore, in the general practice group there was a significant increase in satisfaction over baseline; a similar significant increase in satisfaction over baseline was not found in the hospital group.

CONCLUSION

Patients with breast cancer were more satisfied with follow-up in general practice than in hospital outpatient departments. When discussing follow-up with breast cancer patients, they should be provided with complete and accurate information about the goals, expectations, and limitations of the follow-up programme so that they can make an informed choice.

Influence of maternal nutrition on outcome of pregnancy: prospective cohort study

OBJECTIVE

To investigate the relations of maternal diet and smoking during pregnancy to placental and birth weights at term.

DESIGN

Prospective cohort study.

SETTING

District general hospital in the south of England.

PARTICIPANTS

693 pregnant nulliparous white women with singleton pregnancies who were selected from antenatal booking clinics with stratified random sampling.

MAIN OUTCOME MEASURES

Birth and placental weights at term.

RESULTS

Placental and birth weights were unrelated to the intake of any macronutrient. Early in pregnancy, vitamin C was the only micronutrient independently associated with birth weight after adjustment for maternal height and smoking. Each ln mg increase in vitamin C was associated with a 50.8 g (95% confidence interval 4.6 g to 97.0 g) increase in birth weight. Vitamin C, vitamin E, and folate were each associated with placental weight after adjustment for maternal characteristics. In simultaneous regression, however, vitamin C was the only nutrient predictive of placental weight: each ln mg increase in vitamin C was associated with a 3.2% (0.4 to 6.1) rise in placental weight. No nutrient late in pregnancy was associated with either placental or birth weight.

CONCLUSIONS

Concern over the impact of maternal nutrition on the health of the infant has been premature. Maternal nutrition, at least in industrialised populations, seems to have only a small effect on placental and birth weights. Other possible determinants of fetal and placental growth should be investigated.

Follow-up of breast cancer in primary care vs specialist care: results of an economic evaluation

A randomized controlled trial (RCT) comparing primary-care-centred follow-up of breast cancer patients with the current standard practice of specialist-centred follow-up showed no increase in delay in diagnosing recurrence, and no increase in anxiety or deterioration in health-related quality of life. An economic evaluation of the two schemes of follow-up was conducted concurrent with the RCT Because the RCT found no difference in the primary clinical outcomes, a cost minimization analysis was conducted. Process measures of the quality of care such as frequency and length of visits were superior in primary care. Costs to patients and to the health service were lower in primary care. There was no difference in total costs of diagnostic tests, with particular tests being performed more frequently in primary care than in specialist care. Data are provided on the average frequency and length of visits, and frequency of diagnostic testing for breast cancer patients during the follow-up period.

Randomized trial of nurse-assisted strategies for smoking cessation in primary care

BACKGROUND

Brief advice to stop smoking from general practitioners (GPs) has been repeatedly shown to increase smoking cessation by a small, but measurable amount. Some studies have suggested that adding more intensive interventions to brief advice may increase its effectiveness, but it is unclear whether this is true in general practice.

AIMS

To determine whether brief advice from a doctor together with counselling and follow-up from a trained practice nurse is more effective than brief advice alone in helping people to stop smoking.

METHODS

The design was a randomized controlled trial. Four hundred and ninety-seven general practice patients aged older than 18 years and smoking at least one cigarette per day in six general practices in Oxfordshire, Berkshire, and Buckinghamshire were randomized to one of two interventions: brief verbal or written advice from a GP plus extended counselling and follow-up from a trained practice nurse; brief advice from a GP alone. The primary outcome was sustained abstinence from smoking at three and 12 months. A secondary outcome was forward movement in the stages of change cycle.

RESULTS

The proportion showing sustained abstinence was 3.6% in the extended counselling group, and 4.4% in the brief advice group (difference = -0.8%; 95% confidence interval = -4.3% to 2.6%). Seventy-four (30%) of those randomized to extended counselling actually took up this offer. No significant progression in stages of change was detected between the two groups.

CONCLUSIONS

In unselected general practice patients who smoke, brief advice from a GP combined with intensive intervention and follow-up by a practice nurse is no more effective than brief advice alone.

General practitioners' views on genetic screening for common diseases

In a questionnaire survey of 359 general practitioners (response rate 94%), 60% accepted the need to provide genetic services, but far fewer felt competent to do so. Nevertheless, as many as 76% had referred patients to a genetics unit in the past year, and 50% had counselled about genetics.

Folates in the periconceptional period: are women getting enough?

OBJECTIVE

To examine the prevalence of folic acid supplementation prior to conception and in the first trimester of pregnancy, and to identify sociodemographic variables associated with the use of supplements.

DESIGN

Observational study.

SETTING

District general hospital in the south in England.

POPULATION

Nine hundred and sixty-three randomly selected pregnant nulliparous caucasian women recruited from May 1994 to February 1996 inclusive.

METHODS

Questionnaire administered at approximately 16 weeks gestation.

MAIN OUTCOME MEASURES

Intakes of supplemental folic acid before conception and during pregnancy.

RESULTS

31.5% (303/963) (95% CI 28.5-34.4) of pregnant women reported using supplements containing folic acid prior to conception. The proportion using pre-conceptional folic acid increased by approximately 1% per month during the 22 months of the study. 38.1% (367/962) (35 1 to 41.2) of women began taking folic acid only after the confirmation of pregnancy, and this proportion appeared constant over time. Young age, smoking and low educational attainment were statistically significant predictors of failure to use folic acid both before and during pregnancy.

CONCLUSIONS

Use of folic acid before conception in nulliparous women is much higher than the 2% to 3% reported in earlier studies of all pregnant women, and appears to be increasing. However, many women still only begin taking folic acid after conception, despite current health education strategies. New approaches, focusing on women who are currently least likely to take folic acid those who are young, are of low educational backgrounds, and are smokers - may now be required. Given the inevitably of unplanned pregnancies, efforts must also be made to increase the currently static uptake of folic acid immediately after the confirmation of pregnancy.

A comparison of two methods of follow-up in a trial of prophylactic volume expansion in preterm babies

The outcome at age 2 years of preterm babies recruited into a three-arm randomised controlled trial of prophylactic volume expansion was ascertained in two ways: from a neurodevelopmental assessment performed by a paediatrician and from responses on a brief questionnaire completed by the child's personal health visitor. Of 776 babies recruited into the trial, 604 survived to the age of 2 years and the findings of a paediatric assessment were available for all survivors. Questionnaires were sent to the health visitors of 601 of the survivors; 513 (85.4%) were returned. There was sufficient information on the returned questionnaires to categorise 449 of the children as normal, impaired, moderately disabled or severely disabled. We were unable to detect a response bias by severity of disability. Agreement on individual questions ranged between 86.3% and 98.4%. There was some mismatch in the reporting of vision (weighted kappa = 0.71) and hearing (weighted kappa = 0.73), with differences in perception of level of severity of sensory loss. Health visitors tended to underestimate the child's functional level compared with the paediatrician. However, of 56 children classified as severely disabled by the paediatrician, 48 were classified similarly and eight as moderately disabled on the basis of the questionnaire. The end point of the trial was death or severe disability at 2 years of age. There was close similarity in the trial results whether based on the paediatric assessment or on the questionnaire. Further refinement of the questionnaire is needed, but this methodology may be useful in ascertaining the frequency of severe disability in large cohorts of babies.

Lack of willpower or lack of wherewithal? "Internal" and "external" barriers to changing diet and exercise in a three year follow-up of participants in a health check

The aims of this paper were to assess whether anticipated barriers to change in diet and exercise which were cited before a health check intervention were related to subsequent behaviour changes. In 1989 a health and lifestyle questionnaire was posted to 17,965 people aged 35-64 who were registered with five general practices in Bedfordshire. Taking account of non-contacts, a response rate of 80.3% was achieved and 11,090 people described their exercise and dietary habits. Those expressing an interest in changing each behaviour were asked to identify reasons why change might be difficult. Two types of barriers--"internal" and "external"--were identified. A total of 2205 respondents were invited to attend a health check in Year One and a recheck three years later and 1660 attended. In this subgroup improvement in exercise and diet was examined in relation to the participants' baseline characteristics, including the type of barriers selected. Internal barriers to change (e.g. lack of willpower, too lazy, too busy) were chosen most frequently. In a logistic regression including a range of baseline variables those who selected only internal barriers were less likely to take more exercise (OR 0.59, 95% CI 0.41, 0.86) than those who cited only external (e.g. no transport, can't afford sports facilities) or mixed barriers to changing. There was a similar but not statistically significant trend for changing diet (OR 0.78, 95% CI 0.48, 1.28). Those who are aware of external limitations may be better placed to circumvent them. Further research is needed to explore this relationship between type of barrier and behaviour change.

Smoking cessation interventions for dental patients--attitudes and reported practices of dentists in the Oxford region

OBJECTIVE

To investigate various aspects of dentists' beliefs and practices with respect to helping their patients stop smoking.

DESIGN

Postal questionnaire survey conducted in 1996.

SETTING

The general dental practitioners on the health authority lists of Berkshire, Buckinghamshire, Northamptonshire and Oxfordshire.

SUBJECTS

The 869 dentists registered on 1 April 1996.

RESULTS

A high response rate (78%; 674/869) was obtained. The majority of respondents (82%; 95% CI: 79, 85) thought dentists should encourage their patients to stop smoking although only 37% (95% CI: 34, 41) believed dentists to be effective in smoking cessation and even fewer (18%; 95% CI: 15, 21) routinely recorded their patients' smoking status. Of respondents, 51% (95% CI: 46, 55) said they always discussed smoking with patients who had periodontal problems but only 9% (95% CI: 7, 12) always did so with patients who had no major oral health problem. Newer graduates were more likely to routinely record their patients' smoking status (P = 0.02), and to think that doctors' advice (P = 0.001) and nicotine replacement therapy (P < 0.001) were effective in promoting smoking cessation. Dentists in mainly private practices were more active than those in NHS or mixed practices in recording patients' smoking status (P < 0.001) and in discussing smoking (P = 0.002).

CONCLUSIONS

Most respondents thought that dentists should encourage their patients to stop smoking but few are active in this area.

Evaluation of computer support for prescribing (CAPSULE) using simulated cases

OBJECTIVE

To evaluate the potential effect of computer support on general practitioners' prescribing, and to compare the effectiveness of three different support levels.

DESIGN

Crossover experiment with balanced block design.

SUBJECTS

Random sample of 50 general practitioners (42 agreed to participate) from 165 in a geographically defined area of Oxfordshire.

INTERVENTIONS

Doctors prescribed for 36 simulated cases constructed from real consultations. Levels of computer support were control (alphabetical list of drugs), limited support (list of preferred drugs), and full support (the same list with explanations available for suggestions).

MAIN OUTCOME MEASURES

Percentage of cases where doctors ignored a cheaper, equally effective drug; prescribing score (a measure of how closely prescriptions matched expert recommendations); interview to elicit doctors' views of support system.

RESULTS

Computer support significantly improved the quality of prescribing. Doctors ignored a cheaper, equally effective drug in a median 50% (range 25%-75%) of control cases, compared with 36% (8%-67%) with limited support and 35% (0-67%) with full support (P < 0.001). The median prescribing score rose from 6.0 units (4.2-7.0) with control support to 6.8 (5.8 to 7.7) and 6.7 (5.6 to 7.8) with limited and full support (P < 0.001). Of 41 doctors, 36 (88%) found the system easy to use and 24 (59%) said they would be likely to use it in practice.

CONCLUSIONS

Computer support improved compliance with prescribing guidelines, reducing the occasions when doctors ignored a cheaper, equally effective drug. The system was easy to operate, and most participating doctors would be likely to use it in practice.

Comparing two methods of follow up in a multicentre randomised trial

AIMS

To evaluate a parental questionnaire as a means of providing outcome measures for a multicentre randomised controlled trial of treatment for post-haemorrhagic ventricular dilatation.

METHODS

The parents of 88 survivors were sent a questionnaire before a paediatric assessment at the age of 30 months. The parents' responses to individual questions taken mainly from the Griffiths' mental development scales and their perception of the child's ability to see and hear were compared with the paediatric findings. A model, based on the parents' responses to particular questions, allowed the categorisation of the children as normal, impaired, moderately or severely disabled; this was compared with similar categorisation based on the full paediatric assessment.

RESULTS

Agreement on items concerning gross motor function ranged between 81 and 99%, concerning dressing between 77 and 80%, concerning feeding between 91 and 99%, and concerning language between 85 and 93%. Similar proportions of children were identified as disabled by the parents (60%) and by the paediatrician (66%). Of 29 children who had developmental quotients less than 70, parents identified 28 as disabled, 18 of them as severely disabled. They were not so good at identifying children with impairments without functional loss.

CONCLUSIONS

Further work is required but there is sufficient encouragement from the results to pursue this methodology further for use in comparing groups in randomised trials.

Routine follow up of breast cancer in primary care: randomised trial

OBJECTIVE

To assess the effect on time to diagnosis of recurrence and on quality of life of transferring primary responsibility for follow up of women with breast cancer in remission from hospital to general practice.

DESIGN

Randomised controlled trial with 18 month follow up in which women received routine follow up either in hospital or in general practice.

SUBJECTS AND SETTING

296 women with breast cancer in remission receiving regular follow up care at district general hospitals in England.

MAIN OUTCOME MEASURES

Time between first presentation of symptoms to confirmation of recurrence; quality of life measured by specific dimensions of the SF-36 schedule, the EORTC symptom scale, and hospital anxiety and depression scale.

RESULTS

Most recurrences (18/26, 69%) presented as interval events, and almost half (7/16, 44%) of the recurrences in the hospital group presented first to general practice. The median time to hospital confirmation of recurrence was 21 days in the hospital group (range 1-376 days) and 22 days in the general practice group (range 4-64). The differences between groups in the change in SF-36 mean scores from baseline were small: -1.8 (95% confidence interval -7.2 to 3.5) for social functioning, 0.5 (-4.1 to 5.1) for mental health, and 0.6 (-3.6 to 4.8) for general health perception. The change from baseline in the mean depression score was higher in the general practice group at the mid-trial assessment (difference 0.6, 0.1 to 1.2) but there was no significant difference between groups in the anxiety score or the EORTC scales.

CONCLUSION

General practice follow up of women with breast cancer in remission is not associated with increase in time to diagnosis, increase in anxiety, or deterioration in health related quality of life. Most recurrences are detected by women as interval events and present to the general practitioner, irrespective of continuing hospital follow up.

Hormone replacement therapy: characteristics of users and non-users in a British general practice cohort identified through computerised prescribing records

STUDY OBJECTIVE

To assess the feasibility of recruiting a cohort of women, including long term users of postmenopausal hormone replacement therapy (HRT), through computerised general practice prescribing records, and to compare clinical and demographic characteristics of users and non-user controls.

DESIGN

Cross sectional analysis of questionnaire data.

SETTING

Subjects were recruited through 17 general practices in the Oxfordshire, south west Thames, and north west Thames regions that contributed to the VAMP Research Database.

PARTICIPANTS

A total of 2964 women aged 45-64 years were identified. Altogether 1482 were long term (> 1 year) users of HRT and 1482 were non-user controls: 1037 (70%) of the users and 819 (55.3%) of the controls agreed to participate and provided questionnaire data.

MAIN RESULTS

Users of HRT were more likely to have undergone hysterectomy than controls. Most women with a history of hysterectomy used unopposed oestrogen, while those with intact uteri generally used a combination of oestrogen and a progestagen. Among women who had undergone hysterectomy, HRT users did not differ significantly from controls over a range of demographic and clinical characteristics but they were more likely to be past users of oral contraceptives. Among women with intact uteri, users were similar to controls in terms of reported clinical characteristics, but were of higher social class and were more likely to be past users of oral contraceptives and to have had a mammogram after the age of 50. Compared with the general population, all categories of women recruited to the study were of higher social class and exhibited more health conscious behaviours.

CONCLUSIONS

Electronic general practice prescribing records provide a feasible and efficient method for recruiting women to a cohort of HRT. Women who agreed to participate in this study were not representative of the general population, emphasising the importance of internal controls in such a study. Among participants, HRT users who had not undergone hysterectomy showed evidence of better health than non-users on some dimensions. In the whole sample, however, there were no appreciable differences in social class and self reported health indicators between users and controls.

A controlled assessment of the in vitro fertilization performance of British women of Indian origin compared with white women

OBJECTIVE

To compare the reproductive performance of Indian versus white women in IVF.

DESIGN

Controlled comparative clinical study.

SETTING

In vitro fertilization center based in university department in large tertiary level hospital.

PATIENTS

Results from first IVF treatment cycles in 44 Indian patients were compared with results from 88 white patients, matched by age and body mass index, over the same treatment year. The patients were selected from a prospectively collected IVF databank.

INTERVENTIONS

Standard luteal-phase start long GnRH analogue regime. Ovarian stimulation with FSH and hMG. Transvaginal ultrasound-guided oocyte recovery. In vitro fertilization and ET following established protocols.

MAIN OUTCOME MEASURES

Rates of abandoned cycles, egg retrievals, ETs, clinical pregnancies, miscarriages, and live births were compared in the first IVF treatment cycle. Cumulative pregnancy rates (PRs) over three cycles in the two groups of patients were also compared.

RESULTS

More cycles were abandoned in the Indian than in the white group: 22.7% versus 9.1%. The Indian live birth rate per cycle was worse: 9.1% versus 22.7%. The performance of the two groups was otherwise similar: ovarian stimulation with hMG and FSH required 26.0 required 26.0 ampules in the Indian group versus 24.6 ampules in the white group, mean number of follicles on the day of egg retrieval 8.7 versus 8.7, mean number of eggs 5.9 versus 5.8, fertilization rate 82.4% versus 82.5%; ET rate 73.5% versus 82.5, mean number of embryos transferred 2.1 versus 1.8, and clinical PR per cycle started 18.2% versus 27.3%.

CONCLUSIONS

Under the same IVF regime, Indians performed worse than whites at the stage of ovarian stimulation (higher rate of abandoned cycles for poor response) and in live birth rate. Cumulative conception and live birth rates also tended to be worse in Indians than in whites.

Evaluating primary care follow-up of breast cancer: methods and preliminary results of three studies

OBJECTIVE

To evaluate a primary care centred system of routine follow-up of women with breast cancer in remission. DESIGN, PATIENTS AND OUTCOME MEASURES: Three related studies are reported: 1) A randomized controlled trial (RCT) involving 296 women with breast cancer in remission (stage I, II, or III) all receiving routine follow-up at two district general hospitals in England. Women in the control group received follow-up in hospital clinics according to the usual practice. Women in the experimental group received follow-up from their own general practitioners (GP), and were referred back to hospital clinics if any breast cancer related problems developed. The main outcome of the trial was 'diagnostic delay': the time from the first presentation of signs or symptoms suggestive of recurrence to the time that recurrence was diagnosed. 2) A prospective descriptive study of a cohort of 141 women who were eligible for the trial, but who declined to participate. 3) A national survey of 376 specialists in breast cancer, and a survey of 226 general practitioners of the patients eligible for the RCT described above, to determine their views on follow-up of breast cancer in remission.

RESULTS

1) The randomized trial to evaluate primary care follow-up of breast cancer in remission has been successfully conducted and final results are pending. 2) Patients who were eligible but declined to participate in the trial were significantly older than participants (mean age 64.3 years compared with 60.7 years; difference 3.6 years; 95% confidence interval 0.53; 6.59). The two groups were similar in clinical characteristics and quality of life. 3) The majority of specialists and GPs preferred a system of routine follow-up which was primarily provided by their own professional group.

CONCLUSIONS

A general practice centred system of routine follow-up of women with breast cancer in remission is acceptable to both patients and general practitioners. Final results of a randomized trial evaluating quality of care and quality of life outcome measures are pending.

Cancer in pregnancy

OBJECTIVE

To estimate the incidence of cancer arising in pregnancy and to report its recurrence in those women with a past history of the disease.

DESIGN

Retrospective study over 11 years.

SETTING

John Radcliffe Maternity Hospital.

PATIENTS

25,568 Oxford District Health Authority residents who delivered at the John Radcliffe Maternity Hospital, and 6775 residents who had a termination of pregnancy, between 1 January 1981 and 31 December 1985.

INTERVENTIONS

Retrospective analysis of case records to identify pregnancies complicated by cancer and follow-up through patients' general practitioners.

MAIN OUTCOME MEASURES

Maternal mortality and disease recurrence.

RESULTS

The study identified 32 pregnancies complicated by cancer in 28 women and four terminations of pregnancy performed for cancer as the main or secondary indication. By the end of 1991, three women had died, one woman had been treated for disease recurrence, 17 women were in good health and seven women had been lost to follow-up. There were six cases of cancer arising de novo in pregnancy, i.e. an incidence of 2.35 per 10,000 deliveries (95% confidence interval 0.47 to 4.22). Only one pregnancy was complicated by disease recurrence.

CONCLUSION

The incidence of cancer arising de novo in pregnancy is lower than the most quoted figure of 9.92 per 10,000 pregnancies.

Functional abilities at age 4 years of children born before 29 weeks of gestation

OBJECTIVES

To assess the rate of impairment and disability among babies born very preterm and to investigate the association between such impairment and gestational age at birth.

DESIGN

Cohort study of a geographically defined population of babies.

SETTING

Oxford Regional Health Authority.

SUBJECTS

All babies born alive before 29 weeks of gestation to mothers resident in the region during 1984-6.

MAIN OUTCOME MEASURES

Survival rates and rates of impairment and disability among survivors at the age of 4 years.

RESULTS

Of the 342 babies, half (170) survived to be discharged home. Of the 164 survivors to age 4 years, 153 (93%) were assessed. A total of 35 (23%; 95% confidence interval 16% to 30%) were severely disabled and only 54 (35%; 28% to 43%) were unimpaired. The risk of impairment and disability increased with decreasing gestational age at birth (p < 0.003).

CONCLUSIONS

With the increasing survival rate among babies born before 29 weeks of gestation, we need urgently to establish reliable ways of monitoring the proportion of survivors who have a disability.

Factors affecting response to an invitation to attend for a health check

OBJECTIVE

To describe the characteristics of general practice patients who fail to respond to an invitation to attend for a health check, in relation to demographic variables, risk factor status, health status, and attitudes to behaviour modification.

DESIGN

Postal questionnaire before invitation to attend a health check and subsequent record of attendance.

SETTING

Five urban general practices in Bedfordshire, UK.

SUBJECTS

A total of 2678 patients aged 35-64 years were invited for a health check in 1989-90.

RESULTS

The number of patients who did not attend was low overall but was higher among men than women (21 v 15%, p < 0.001), and in unmarried than married patients (24 v 16%, p < 0.001). Failure to attend was also higher among people in manual than in non-manual occupations (21 v 15%, p < 0.001), in people living in rented accommodation than in homeowners (29 v 16%, p < 0.001), and in those without access to a car than in car users (27 v 16%, p < 0.001). There was no difference in non-attendance rate according to age at completion of full time education. After adjustment for age, sex, marital state, and social class, the odds ratio for non-attendance was 1.74 (95% confidence interval (CI) 1.41, 2.14) for smokers; 1.07 (95% CI 0.76, 1.51) for heavy drinkers; 1.91 (95% CI 1.41, 2.58) for those with a less healthy diet; and 1.50 (95% CI 1.09, 2.07) for those who were obese. Patients who had visited their general practice more frequently and those who indicated a willingness to change their behaviour were significantly more likely to attend the health check.

CONCLUSIONS

Health check attendance was lowest among patients who rarely attended the surgery and those who reported higher risk behaviour. Attendance was not, however, confined to the 'worried well'. Equal numbers of those with and without chest pain attended, as did at least three quarters of those in each risk group. This high rate of attendance reflects the time and effort invested in systematic recruitment. The development of a robust recruiting strategy is essential if substantial numbers, and particularly those at highest risk, are to be reached.

General practice careers: changing experience of men and women vocational trainees between 1974 and 1989

The aim of this study was to consider the careers pursued by men and women general practitioner trainees following the completion of their training, and to assess changes since 1974. It was based on a postal questionnaire survey involving 995 doctors who had completed general practice vocational training in the Oxford region between 1974 and 1989. A total of 796 doctors replied to the questionnaire (498 men and 298 women, overall response rate 80%). The vast majority of ex-trainees were working in general practice at the time of the survey (men 87%, women 71%). Women were less likely to have become principals than men (75% versus 97%). Most women (71% of those completing training before 1988) reported at least one period of non-employment. While the duration of maternity leave dropped only slightly during the 15 years studied, the length of voluntary and involuntary unemployment experienced by women fell markedly. Men experienced little unemployment with no change in length of unemployment over time. Considerably fewer women than men (6% versus 13%) had become involved in teaching or training. The degree of difficulty in choosing and following a general practice career remained constant over time for women. In contrast there was a significant increase in the difficulties experienced by men. The proportion of men and women completing training in 1984-89 who found following a general practice career 'difficult or very difficult' was similar (10% of men, 13% of women). The possibility of improving these experiences, particularly by encouraging flexibility in the early years after completion of training, is discussed.

Breast self examination and survival from breast cancer

The survival of 616 women aged 15-59 with breast cancer, 226 of whom had been taught and practised breast self examination (BSE) prior to diagnosis and 390 of whom had not, is reported. Six year survival rates were 73.1% in the BSE taught group and 66.1% in other women (P = 0.07).

Motivational effect of cholesterol measurement in general practice health checks

A randomized trial was conducted in five general practices in and around Aylesbury, Buckinghamshire to assess the motivational effect of cholesterol measurement on compliance with advice to reduce dietary fat intake and to stop smoking. The advice was given by practice nurses during health checks for cardiovascular risk factors. A total of 578 patients were recruited to the study and randomized into two groups. Both groups were given the same advice and were followed up after a median of three months, but the intervention group was also given immediate feedback on their cholesterol concentration. Follow up was completed for 88.2% of subjects, and those who were not followed up were assumed not to have changed their behaviour. The mean fall in total cholesterol at follow up was 0.11 mmol l-1 (95% confidence interval 0.03 to 0.18) in the intervention group who were told their cholesterol result and 0.02 mmol l-1 (95% CI -0.06 to 0.10) in the control group who were not. The proportion of smokers who were not smoking at follow up was 10.7% and 10.1% in the two groups, respectively. Patients in the intervention group with an initial total cholesterol level of 6.50 mmol l-1 or greater showed a mean fall of 6.2% in cholesterol level whereas those with an initial cholesterol level of less than 5.20 mmol l-1 experienced a mean increase of 3.6%, but as differences of this magnitude were also seen in the control group they probably reflect regression to the mean rather than an effect of knowledge of cholesterol level.(ABSTRACT TRUNCATED AT 250 WORDS)

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.
