General practitioners, students and the objectives of general practice attachments.

The objectives for undergraduate experience in general practice vary little from school to school although the timing and duration of attachment does. Students' views of the relevance and achievement of these objectives to a two-week attachment in the final year of St. George's Hospital Medical Schools' old curriculum are shown to differ from those of their GPs. The implications of these differences for planning undergraduate learning in general practice are discussed.

Putative temperament of patients with generalized anxiety disorder: two-years' interval test-retest reliability of a Japanese version of the Generalized Anxious Temperament.

This study examined long-interval test-retest reliability of the Generalized Anxious Temperament (GAT) Japanese version, which is a self-rated questionnaire to measure the temperament of patients with generalized anxiety disorder (GAD). First, we investigated the prevalence of GAT in 214 healthy Japanese subjects (107 females and 107 males). Second, we administered GAT to the 117 (77 females and 40 males) patients with GAD, together with GAF (Global Assessment of Functioning) and HAM-A (Hamilton Anxiety Scale), and readministered after 2 years to examine its reliability. GAT showed good test-retest reliability (Pearson's correlation coefficient = 0.8). Cronbach's alpha of the 26 GAT items was 0.93 that indicated a high level of internal consistency. GAT scores were not influenced by psychological, social or occupational functioning, nor by anxiety symptoms and remained stable over 2 years. GAT scores did not correlate with the age or sex of the control subjects. GAT scores were higher in patients with GAD than they were in control subjects, particularly in females. Twenty-three of 26 GAT items were significantly higher in patients with GAD than in healthy subjects. Stepwise multiple regression analysis revealed that GAT scores in patients with GAD were higher in females than in males (P < 0.01) and in those with early onset of the disorder (P < 0.05). These results suggest that the anxious temperament appears to increase the risk of early onset of GAD, particularly in females. This long interval and large sample research of test-retest reliability on GAT indicated its usefulness for understanding the core features of GAD.

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).

Medical audit in general practice. II: Effects on health of patients with common childhood conditions. North of England Study of Standards and Performance in General Practice.

OBJECTIVE: To estimate the effects of medical audit, particularly setting clinical standards, on patients' health. DESIGN: Before and after study strengthened by a replicated Latin square. SETTING: 62 training general practices in the north of England. PATIENTS: Random sample of 9000 children with any of five conditions--acute cough, acute vomiting, bedwetting, itchy rash, and recurrent wheezy chest--stratified by doctor consulted, condition, and age. INTERVENTIONS: Clinical standard set by each of 10 small groups comprising 84 general practitioner trainers for one randomly selected childhood condition. Each group also experienced a different type of medical audit, randomly selected, for each of the four other study conditions (receiving a clinical standard set by another trainer group, tabulated data comparing clinical performance with that of all other groups, tabulated data from only their own group, and nothing ("control" condition)). MAIN OUTCOME MEASURES: Condition specific, functional, psychological, and educational outcomes; together with parent satisfaction (recorded by home interviews and postal questionnaires). RESULTS: Children consulting trainers for recurrent wheezy chest after those doctors had set a standard for that condition improved both in drug compliance (79% (n = 33) before standard setting v 93% (30) after) and mean number of days of breathlessness (3.8 (SE 1.0) before v 1.7 (0.6) after) and wheeziness (4.7 (0.9) before v 1.8 (0.6) after), compared with those consulting doctors who had not (compliance 74% (144) before v 72% (146) after; breathlessness 2.4 (0.4) before v 2.3 (0.3) after; wheeziness 3.0 (0.4) before v 2.7 (0.4) after). There were no other significant effects of standard setting or audit on patients' health. CONCLUSION: Setting clinical standards improved drug compliance and respiratory function in children with recurrent wheezy chest.

Effectiveness of a nicotine patch in helping people stop smoking: results of a randomised trial in general practice. Imperial Cancer Research Fund General Practice Research Group.

OBJECTIVE: To assess the effectiveness of 12 weeks' treatment with a 24 hour transdermal nicotine patch in helping heavy smokers to stop smoking; also to assess the value of a specially written support booklet about smoking cessation and patch use compared with a simple advice pamphlet. DESIGN: Double blind placebo controlled randomised trial with a 2 x 2 factorial design. SETTING: 19 general practices in Oxfordshire. SUBJECTS: 1686 heavy smokers aged 25-64 (mean cigarette consumption 24/day; mean duration of smoking 25 years). MAIN OUTCOME MEASURE: Sustained cessation for the last four weeks of the 12 week treatment period, confirmed by saliva cotinine estimation (226/262 cases; 86.3%) or expired carbon monoxide concentration (36/262; 13.7%). Patients lost to follow up (155/1686; 9%) were assumed to have continued to smoke. RESULTS: Cessation was confirmed in 163 patients (19.4%) using the nicotine patch and 99 patients (11.7%) using the placebo patch (difference 7.6% (95% confidence interval 4.2% to 11.1%); p < 0.0001). There was no significant advantage in using the more detailed written support material. The most important adverse effect of the patch was local skin irritation, which occurred in 15.8% (133/842) and 5.1% (43/844) of patients using the nicotine and placebo patches respectively, was graded as severe in 4.8% (40) and 1.1% (nine), and was stated as a reason for withdrawal from the trial in 9.5% (80) and 2.8% (24). CONCLUSION: Nicotine patches are effective in a general practice setting with nursing support, but the extent to which this effect is sustained cannot be assessed until the results of longer term follow up are known.

General-practitioner ward in a district general hospital.

A general-practitioner ward, made available at the local hospital, was used by 34 of 64 local practitioners offered contracts by the regional board. Four of the five doctors in our practice took up contracts, and we were responsible for 119 admissions (100 patients) in one year. Had the general-practitioner ward not been available 73 hospital admissions would have been needed; in 27 cases care at home would have been the alternative, while the remaining 19 patients could have been seen as outpatients. Only seven consultant opinions were sought during the year.

Trends in the prevalence and management of atrial fibrillation in general practice in England and Wales, 1994-1998: analysis of data from the general practice research database.

OBJECTIVE: To determine the prevalence of atrial fibrillation in England and Wales, and examine trends in its treatment with warfarin and aspirin between 1994 and 1998. DESIGN: Analysis of data from the general practice research database. SETTING: England and Wales. PATIENTS: 1.4 million patients registered with 211 general practices. MAIN OUTCOME MEASURES: Age and sex specific prevalence rates of atrial fibrillation; percentage of patients with atrial fibrillation treated with oral anticoagulants or aspirin. RESULTS: The prevalence of atrial fibrillation in 1998 was 12.1/1000 in men and 12.7/1000 in women. Prevalence increased from less than 1/1000 in under 35 year olds to over 100/1000 in those aged 85 years and over. There was a 22% increase in the age standardised prevalence of atrial fibrillation in men and a 14% increase in women between 1994 and 1998. The percentage of patients prescribed oral anticoagulants increased from 20% to 34% in men and from 17% to 25% in women. The percentage of men with atrial fibrillation prescribed aspirin increased from 26% to 36%, and the percentage of women increased from 24% to 36%. Applying the age and sex specific prevalence and treatment rates to the population gives an estimate of around 650 000 cases of atrial fibrillation in England and Wales. The greatest number of cases occurs in the 75-84 year old age group. CONCLUSIONS: The number of patients in the community with identified atrial fibrillation is increasing. There has also been a pronounced increase in the percentage of patients with atrial fibrillation prescribed oral anticoagulants or aspirin.

Can postal prompts from general practitioners improve the uptake of breast screening? A randomised controlled trial in one east London general practice.

OBJECTIVE: To determine the effect on the uptake of breast screening of a personalized letter from the general practitioner recommending mammography, sent to coincide with an invitation from the NHS breast screening programme. DESIGN: Randomised control trial with stratification of prognostic variables. SETTING: A group practice in Hackney, east London. SUBJECTS: 473 women invited for breast screening by the City and East London Breast Screening Service. OUTCOME MEASURE: Attendance for mammography. RESULTS: All women in the randomised trial were followed up; 134 of 236 (57%) randomly allocated to receive the prompting letter attended for mammography compared with 120 of 234 (51%) controls This difference was not significant (chi 2 = 1.43, p = 0.23) CONCLUSION: Personal recommendation by a letter prompting attendance for mammography from the general practitioner known best to women due to be screened did not improve uptake of breast screening in this east London practice. Other strategies are needed to increase uptake of mammography in inner cities.

Management of chronic heart failure: perceived needs of general practitioners in light of the new general medical services contract.

BACKGROUND: Despite the existence of several chronic heart failure (CHF) guidelines the treatment of patients with CHF is suboptimal. The new general medical services (GMS) contract in primary care has only three specific performance indicators for patients with left ventricular dysfunction. The aim of this current questionnaire survey was to assess the views of general practitioners (GPs) on CHF treatments and services in light of the new GMS contract. METHODS AND RESULTS: All local GPs (717) were sent a questionnaire. Fifty three per cent were returned. Forty five per cent of GPs had access to a community CHF nurse. Having read a national guideline (SIGN) and having the support of a CHF nurse did not seem to affect the knowledge of GPs in terms of perceived benefits of drug treatments. GPs with access to a specialist CHF nurse service attached more importance to it than those with no specialist nurse (p = 0.003). CONCLUSIONS: Most GPs were aware of the existence of a national guideline but many had not read it. There was little or no difference in the knowledge level for various evidence based treatments between GPs who had or had not read the guideline suggesting that reading guidelines may not be a key factor in determining knowledge. Support for a specialist CHF nurse was higher among GPs who already had this service, suggesting that this service is valued. The new GMS contract may improve identification and diagnosis of patients with CHF but there is a danger that it may fall short of ensuring optimal treatment for patients with CHF.

Use of the General Practice Research Database (GPRD) for respiratory epidemiology: a comparison with the 4th Morbidity Survey in General Practice (MSGP4).

BACKGROUND: The General Practice Research Database (GPRD) covers over 6% of the population of England and Wales and holds data on diagnoses and prescribing from 1987 onwards. Most previous studies using the GPRD have concentrated on drug use and safety. A study was undertaken to assess the validity of using the GPRD for epidemiological research into respiratory diseases. METHODS: Age-specific and sex-specific rates derived from the GPRD for 11 respiratory conditions were compared with patient consultation rates from the 4th Morbidity Survey in General Practice (MSGP4). Within the GPRD comparisons were made between patient diagnosis rates, patient prescription rates, and patient "prescription plus relevant diagnosis" rates for selected treatments. RESULTS: There was good agreement between consultation rates in the MSGP4 and diagnosis or "prescription plus diagnosis" from the GPRD in terms of pattern and magnitude, except for "acute bronchitis or bronchiolitis" where the best comparison was the combination category of "chest infection" and/or "acute bronchitis or bronchiolitis". Within the GPRD, patient prescription rates for inhalers, tuberculosis or hayfever therapy showed little similarity with diagnosis only rates but a similarity was seen with the combination of "prescription plus diagnosis" which may be a better reflection of morbidity than diagnosis alone. CONCLUSIONS: The GPRD appears to be valid for primary care epidemiological studies by comparison with MSGP4 and offers advantages in terms of large size, a longer time period covered, and ability to link prescriptions with diagnoses. However, careful interpretation is needed because not all consultations are recorded and the coding system used contains terms which do not directly map to ICD codes.

Clinical uroselectivity: a 3-year follow-up in general practice. BPH Group in General Practice.

The objectives of this open-labeled study were to assess the clinical uroselectivity of alfuzosin in a long-term follow-up study in general practice. A total of 3,228 patients with clinical benign prostatic hyperplasia (BPH) from 812 centers were included in a prospective 3-year open-labeled study and treated with alfuzosin (immediate-release formulation) at the recommended dosage. Symptom score (Boyarsky, modified) and a 20-item BPH-specific health related quality of life (HRQL) score (Urolife BPH QoL 20), which included three questions on sexuality, were self-administered at baseline, 3, 6, 12, 18, 24, 30 and 36 months. Symptom score was significantly reduced by 54% at 3 months and this reduction was maintained up to 36 months; the HRQL score was significantly improved by 45.4% at 12 months and this improvement was also maintained up to 36 months. Alfuzosin was well tolerated: the quantitative and qualitative distribution of adverse events (AEs) was similar to that previously observed in placebo-controlled studies. 4.2% of the patients dropped out due to AEs. This study confirms the long-term safety profile of alfuzosin in general practice and highlights the need to measure HRQL in the context of clinical uroselectivity.

National General Practice Study of Epilepsy and Epileptic Seizures: objectives and study methodology of the largest reported prospective cohort study of epilepsy. National General Practice Study of Epilepsy and Epileptic Seizures (NGPSE).

Most available data on the prognosis of epileptic seizures come from hospital-based clinics in which patients with chronic or severe disease are over-represented. The National General Practice Study of Epilepsy and Epileptic Seizures is a large prospective community-based study of people with newly diagnosed seizures which aims to address questions related to the early prognosis of epilepsy. 275 general practitioners throughout the United Kingdom have registered a total of 1,195 patients. In this paper we discuss the background to the study and the methodology used.

General population and cancer patient norms for the Functional Assessment of Cancer Therapy-General (FACT-G).

Given the number of new cancer cases diagnosed each year and the increases in survival rates, the importance of having a clinically useful health-related quality of life (HRQOL) instrument has increased. The Functional Assessment of Cancer Therapy-General (FACT-G) is one such instrument that has been used worldwide to assess HRQOL. Previously, the use of the FACT-G had been limited because of a lack of published normative data. Normative data are useful for consumers to place their results in an appropriate context by comparing their scores of individuals or group of individuals to a reference group. Here, we present normative data for the FACT-G for two reference groups: (a) a sample of the general U.S. adult population and (b) a large, heterogeneous sample of adult patients with cancer. In addition, we demonstrate various uses of the normative data.

A general approach to mixed effects modeling of residual variances in generalized linear mixed models.

We propose a general Bayesian approach to heteroskedastic error modeling for generalized linear mixed models (GLMM) in which linked functions of conditional means and residual variances are specified as separate linear combinations of fixed and random effects. We focus on the linear mixed model (LMM) analysis of birth weight (BW) and the cumulative probit mixed model (CPMM) analysis of calving ease (CE). The deviance information criterion (DIC) was demonstrated to be useful in correctly choosing between homoskedastic and heteroskedastic error GLMM for both traits when data was generated according to a mixed model specification for both location parameters and residual variances. Heteroskedastic error LMM and CPMM were fitted, respectively, to BW and CE data on 8847 Italian Piemontese first parity dams in which residual variances were modeled as functions of fixed calf sex and random herd effects. The posterior mean residual variance for male calves was over 40% greater than that for female calves for both traits. Also, the posterior means of the standard deviation of the herd-specific variance ratios (relative to a unitary baseline) were estimated to be 0.60 +/- 0.09 for BW and 0.74 +/- 0.14 for CE. For both traits, the heteroskedastic error LMM and CPMM were chosen over their homoskedastic error counterparts based on DIC values.

Factor analysis and validation of the General Health Questionnaire in men: a general practice survey.

As part of a survey of 1011 men aged 20-60 years, a factor analysis and validation study of the General Health Questionnaire (GHQ) was carried out. Three clinically relevant factors could be isolated but factor analysis did not generally enhance the value of the GHQ. When compared with results for a similar group of women, sex differences in answering the GHQ were found; the GHQ was perhaps a less satisfactory screening instrument in the men.

The General Health Questionnaire and the detection of emotional disorder by General Practitioners. A replicated study.

This paper reports on a study of psychiatric morbidity in 920 patients attending 18 General Practitioners in Lewisham, South East London. Two indices of morbidity were computed on the basis of the patients responses to the General Health Questionnaire (GHQ) and the GPs' own estimates. Indices of the GPs' detection ability were found by comparing questionnaire and GP rating. The results are compared to those obtained by other workers in a sample of Manchester GPs. The GHQ gave a prevalence estimate of 42.9% which is comparable to that of 39.6% obtained in the Manchester study. In addition, the variation in caseness across sociodemographic groups was consistent with the Manchester findings. The GPs' estimates of morbidity, while much lower than those obtained in Manchester, have similar sociodemographic profiles. The results support the use of the GHQ as a screening device in epidemiological studies, and suggest the need for further investigation of the individual GP's performance as a case detector.

National General Practice Study of Epilepsy (NGPSE): partial seizure patterns in a general population.

The National General Practice Study of Epilepsy (NGPSE) is a prospective community-based study of newly diagnosed epileptic seizures. Of 594 patients with definite epileptic seizures, 160 (26.9%) had seizures with a clinically localizable onset: 36 (22.5%) frontal, 52 (32.5%) central sensorimotor, 43 (27%) temporal, nine (5.6%) frontotemporal, and 10 each (6.3%) parietal and other posterior cortex. There was no difference among these groups in seizure frequency or remission rate; 46.5% were seizure free and 6.9% had severe epilepsy. Etiology was identifiable in 41% and focal CT and EEG abnormalities in 33% and 19%, with results discordant with the clinical seizure localization in 21% and 20%. Temporal lobe epilepsy may be underreported, as it may be more difficult to localize clinically. Extratemporal seizures are extremely common in the general population, especially frontal and central sensorimotor, in relation to cerebrovascular disease. Prognoses are similar for partial epilepsies with different clinical patterns and regions of onset and are much better than suggested in hospital-based studies. The clinical, EEG, and CT localizations may frequently be discordant in this nonrefractory group.

[The practice guideline 'Acute cough' from the Dutch College of General Practitioners; a response from the perspective of general practice].

The practice guideline 'Acute cough' from the Dutch College of General Practitioners stresses the fact that a cough of less than 3 weeks' duration seldom heralds serious pathology. However, for sound reassurance of patients presenting with a cough of short duration, the general practitioner needs to know much about the signs and symptoms connected to low-prevalence serious pathology in these patients. The practice guideline distinguishes upper and lower respiratory tract infections and defines serious lower respiratory tract infection. The diagnostic value of symptoms and laboratory findings like a sedimentation rate or C-reactive protein in order to make such distinctions, is not explained in detail. Antibiotics are reserved for serious lower respiratory tract infection with the exception of acute bronchitis, croup and bronchiolitis, which can be treated without antibiotics. Recommendations for treatment of acute bronchiolitis with bronchodilators or corticosteroids, and croup with corticosteroids are based on consensus. This practice guideline can be considered as a clear and valuable piece of work for all physicians in primary and secondary care.
