Specialist outreach clinics in general practice.

OBJECTIVES--To establish the extent and nature of specialist outreach clinics in primary care and to describe specialists'' and general practitioners'' views on outreach clinics. DESIGN--Telephone interviews with hospital managers. Postal questionnaire surveys of specialists and general practitioners. SETTING--50 hospitals in England and Wales. SUBJECTS--50 hospital managers, all of whom responded. 96 specialists and 88 general practitioners involved in outreach clinics in general practice, of whom 69 (72%) and 46 (52%) respectively completed questionnaires. 122 additional general practitioner fundholders, of whom 72 (59%) completed questionnaires. MAIN OUTCOME MEASURES--Number of specialist outreach clinics; organisation and referral mechanism; waiting times; perceived benefits and problems. RESULTS--28 of the hospitals had a total of 96 outreach clinics, and 32 fundholders identified a further 61 clinics. These clinics covered psychiatry (43), medical specialties (38), and surgical specialties (76). Patients were seen by the consultant in 96% (107) of clinics and general practitioners attended at only six clinics. 61 outreach clinics had shorter waiting times for first outpatient appointment than hospital clinics. The most commonly reported benefits for patients were ease of access and shorter waiting times. CONCLUSIONS--Specialist outreach clinics cover a wide range of specialties and are popular, especially in fundholding practices. These clinics do not seem to have increased the interaction between general practitioners and specialists.     

Computerization of family practice.

The primary focus of computer systems for family practice is on patient billing. Primary care physicians should be aware of the many other benefits that can and should be considered when planning a system for their practice. This article describes the type and extent of information that can be stored in a family practice data base and explores some of the applications in areas of practice and patient management, prevention and research.     

Epidemiology of endometriosis in women attending family planning clinics.

OBJECTIVE--To describe the epidemiology of endometriosis in women attending family planning clinics with special reference to contraceptive methods. DESIGN--Non-randomised cohort study with follow up of subjects for up to 23 years. Disease was measured by first hospital admission rates since endometriosis can be diagnosed with accuracy only at laparotomy or laparoscopy. SETTING--17 family planning centres in England and Scotland. SUBJECTS--17,032 married white women aged 25-39 years at entry during 1968-74 who were taking oral contraceptives or using an intrauterine device or diaphragm. About 99% of the women approached agreed to participate and annual loss to follow up was about 0.3%. MAIN OUTCOME MEASURES--Diagnosis of endometriosis, age, parity, and history of contraceptive use. RESULTS--Endometriosis was significantly related to age, peaking at ages 40-44 (chi 2 for heterogeneity = 30.9, p < 0.001). Endometriosis was not linked to duration of taking oral contraceptives. Nevertheless, the risk of endometriosis was low in women currently taking oral contraceptives (relative risk 0.4; 95% confidence interval 0.2 to 0.7), but higher in women who had formerly taken them (1.8; 1.0 to 3.1 in women who had stopped 25-48 months previously) compared with women who had never taken the pill. A similar pattern was seen for use of intrauterine devices (relative risk 0.4 (0.2 to 0.7) in current users and 1.4 (0.4 to 3.2) in users 49-72 months previously compared with never users). No association was found between endometriosis and use of the diaphragm. CONCLUSIONS--Oral contraceptives seem to temporarily suppress endometriosis. Endometriosis may be diagnosed late in women using intrauterine devices as pain and bleeding occur with both.     

Lifestyle assessment: applying microcomputers in family practice.

A randomised trial of assessment by computer was conducted with 180 patients in a family practice clinic. Histories of alcohol, tobacco, and drug use were obtained by computer (n = 60), interview (n = 60), or self completed questionnaire (n = 60). The results of previous research suggest that some patients may provide more accurate information about "sensitive" problems to a computer. No significant differences, however, in levels of consumption or problems were reported for the three methods of assessment. Patients gave differential ratings about the method of assessment, with the computer rated as more interesting but also more mechanical, cold, and impersonal. Although the interview was initially preferred by most, patients who completed the assessment by computer showed a significant increase (13% to 43%) in their preference for the computer after the assessment. The results of our study indicate that patients'' acceptance of computers in family practice may be favourably influenced by direct experience with a microcomputer.     

A survey of postgraduate training for family practice.

The results of a survey of Canadian primary care physicians for the Canadian Medical Association (CMA''s) Task Force on Education for the Provision of Primary Care Services are reported. Recent Canadian medical school graduates in primary care practice reported that the three major training routes (rotating and mixed internships and family medicine residencies) each prepared them differently for practice. The graduates of 2-year family medicine residencies were more satisfied with their preparation than were the graduates of the other major training routes. A 2- or 3-year family medicine residency was preferred by 50% of the respondents, although only 33% of them had actually taken one of these routes. There was considerable agreement in the respondents'' assessments of the types of postgraduate education needed for primary care practice. The results of this survey were consistent with the recommendations in the final report of the CMA''s task force.     

Radioallergosorbent testing for penicillin allergy in family practice.

OBJECTIVES: To determine (a) the prevalence of patients supposedly allergic to penicillin who have a positive radioallergosorbent test (RAST) result for penicillin G or V and (b) the predictive power of family physicians'' clinical judgement that a patient who is supposedly allergic to penicillin will have a positive RAST result. DESIGN: Prospective multicentre cross-sectional observational study. SETTING: Eleven primary care practices in Newfoundland; 10 were in a rural setting. PATIENTS: Of 110 consecutive adult patients with a supposed allergy to penicillin 97 agreed to participate in the study; 92 underwent RAST. INTERVENTIONS: Patients helped physicians complete a questionnaire and had a venous blood sample taken for the RAST. Physicians examined the clinical history and judged whether the patient was likely to have a positive RAST result. MEAN OUTCOME MEASURES: Rates of positive and negative RAST results for penicillin V and G. RESULTS: Of the 92 patients 8 had a positive RAST result and 84 a negative one. The positive predictive power of a "good" clinical history (e.g., urticaria, swollen eyes, tongue or lips, or an anaphylactic reaction witnessed by a physician) was low (10%); the negative predictive power of a "poor" clinical history (e.g., nausea, vomiting, diarrhea, fever, nonspecific rash or fainting) was 92%. CONCLUSIONS: Less than 10% of primary care patients with a supposed allergy to penicillin will have a positive RAST result. In addition, physicians'' predictions of allergy in such patients are imprecise.     

Hypertension in a family practice.

The performance of an urban Canadian family practice in the detection, evaluation, treatment, control and follow-up of hypertension for a 10-year period 1965-74 was reviewed. Vigorous case-finding and treatment were followed by good control of hypertension in 67% of cases and a significant decrease in mortality from stroke and congestive heart failure. It is strongly suggested that the proper location for dealing with hypertension is the primary-care practice and that the general practitioner deserves greater assistance from clinical specialists, health foundations and ministries of health in attacking this problem.     

Managing uncertainty in family practice.

Because patients present in the early stages of undifferentiated problems, the family physician often faces uncertainty, especially in diagnosis and management. The physician''s uncertainty may be unacceptable to the patient and may lead to inappropriate use of diagnostic procedures. The problem is intensified by the physician''s hospital training, which emphasizes mastery of available knowledge and decision-making based on certainty. Strategies by which a physician may manage uncertainty include (a) a more open doctor-patient relationship, (b) understanding the patient''s reason for attending the office, (c) a thorough assessment of the problem, (d) a commitment to reassessment and (e) appropriate consultation.
