Decision making by general practitioners in diagnosis and management of lower urinary tract symptoms in women.

OBJECTIVE--To identify factors influencing decision making by general practitioners in the diagnosis and treatment of lower urinary tract symptoms in women. SETTING--Two suburban London general practices. SUBJECTS--Women presenting to their family doctor with lower urinary tract symptoms. DESIGN--After each consultation the doctor completed a questionnaire on presenting symptoms; clinical examination; investigations undertaken; presence of psychological, social, and menstrual problems; patients'' requests for antibiotics; antibiotic prescribing; knowledge of the patient; attitude towards the consultation; and any other factors assisting in diagnosis and management. Finally, doctors predicted the presence or absence of clinically important bacteriuria. Each woman completed a demographic questionnaire, the 12 item general health questionnaire, and the modified menstrual distress questionnaire, after which each provided a clean catch midstream urine sample. Case notes were examined for information on previous reports of results of urine analysis. RESULTS--When the general practitioners did not know the patients well they were 4.5 times more likely to assume that there was a clinically important infection. When they knew the patient well, they were four times more likely to make a correct prediction of the test result and 12 times less likely to prescribe antibiotics. Doctors were five times more likely to predict the test result correctly in patients from social classes 1 and 2 and were six times more likely to prescribe antibiotics for the older women in the sample. CONCLUSIONS--In women presenting with urinary tract symptoms, these family practitioners seemed to take no particular regard of physical, psychological, or menstrual factors in making their assessments. They were most accurate in their prediction of the result of urine analysis and least likely to prescribe antibiotics when they had a good general knowledge of the patient. Which came first, the diagnosis or prescribing, is difficult to say and probably differed in individual cases. Doctors tended to be more conservative in their management of older women and those whom they knew less well.     

Use of Radiological Facilities by General Practitioners

The 11,360 direct referrals to diagnostic radiological facilities by general practitioners in the Aberdeen area during 1973 were studied. These represented about 12% of the adult radiology performed in the main x-ray departments of the city, and barium meal examinations amounted to half of all such outpatient contrast examinations. Chest x-ray and barium meal examinations were the most frequently used procedures.Some abnormality was detected at 34% of all examinations, and the barium meal examinations requested by general practitioners showed a similar percentage of abnormal findings to those requested by Aberdeen hospital doctors.The average referral rate for all practices was 24·6 per 1,000 practice population per year. Singlehanded general practitioners referred fewer patients for diagnostic radiology than those working in group practices, and rural practitioners referred fewer than urban general practitioners. This trend was emphasized at a distance greater than 15 miles from the city.     

Upper gastrointestinal Kaposi's sarcoma in patients positive for HIV antibody without cutaneous disease

Six patients with antibodies to the human immunodeficiency virus (HIV) and with persistent gastrointestinal symptoms of HIV infection but without cutaneous lesions of Kaposi''s sarcoma underwent endoscopy. Four also underwent barium meal examination. In all six cases small lesions were seen in the stomach at endoscopy, and histological examination of biopsy specimens taken from the lesions confirmed the diagnosis of Kaposi''s sarcoma. The barium meal examinations were reported as normal in three patients and showed oesophageal candidiasis in the fourth.These findings suggest that Kaposi''s sarcoma of the upper gastrointestinal tract is common in patients positive for HIV antibody, even those without cutaneous lesions. Endoscopy, with biopsy of suspicious lesions, is necessary to make the diagnosis and is recommended in all HIV antibody positive patients with persistent upper gastrointestinal symptoms.     

Endoscopic studies of dyspepsia in a general practice.

In an urban general practice serving 7800 patients, all patients presenting over five and a half years with dyspepsia lasting more than two weeks were investigated by fibreoptic endoscopy and cholecystography, and many by barium meal. Of the 393 patients with dyspepsia, 346 completed the investigation: 180 had specific disease of the oesophagus, stomach, duodenum, or gall bladder, including six with carcinoma. Al further 67 had mucosal disease, and only 99 patients had no abnormality. After the first year the number of patients presenting annually and the percentage of patients with specific lesions remained constant. The annual incidence for patients with dyspepsia was about 1% and for patients with specific lesions 0.4%, suggesting that each year those who became symptom free (either spontaneously or because of treatment) were balanced by a similar number who developed symptoms. In contrast to the conclusions of other workers that an "open-access" endoscopy service could not be justified because the number of patients with specific lesins fell during their survey, we suggest that such endoscopy services are indeed worth while for providing an accurate diagnosis of dyspepsia.     

Improving care: a study of orthopaedic outpatient referrals.

OBJECTIVE--To identify aspects of outpatient referral in which general practitioners'', consultants'', and patients'' satisfaction could be improved. DESIGN--Questionnaire survey of general practitioners, consultant orthopaedic surgeons, and patients referred to an orthopaedic clinic. SETTING--Orthopaedic clinic, Doncaster Royal Infirmary. SUBJECTS--628 consecutive patients booked into the orthopaedic clinic. MAIN OUTCOME MEASURES--Views of the general practitioners as recorded both when the referral letter was received and again after the patient had been seen, views of the consultants as recorded at the time of the clinic attendance, and views of the patients as recorded immediately after the clinic visit and some time later. RESULTS--Consultants rated 213 of 449 referrals (42.7%) as possibly or definitely inappropriate, though 373 of 451 patients (82.7%) reported that they were helped by seeing the consultant. Targets for possible improvement included information to general practitioners about available services, communication between general practitioners and consultants, and administrative arrangements in clinics. Long waiting times were a problem, and it seemed that these might be reduced if general practitioners could provide more advice on non-surgical management. Some general practitioners stated that they would value easier telephone access to consultants for management advice. It was considered that an alternative source of management advice on musculoskeletal problems might enable more effective use to be made of specialist orthopaedic resources. Conclusion--A survey of patients'' and doctors'' views of referrals may be used to identify aspects in which the delivery of care could be made more efficient. Developing agreed referral guidelines might help general practitioners to make more effective use of hospital services.     

Laboratory and radiological investigations in general practice. I-Type requested and rate of use.

The use that 30 general practitioners in four group practices made of open access laboratory and radiological facilities was studied for one year. We were particularly interested in whether general practitioners hoped to exclude rather than confirm abnormality when requesting investigations. All but two of the general practitioners studied used investigations to exclude abnormality to a greater extent than to confirm it. The rate at which the practices investigated patients and the number of investigations requested were appreciably different and were different for individual general practitioners, part time general practitioners requesting more investigations than trainees and full time general practitioners. Haematological investigations accounted for over 30% of requests for investigations in all but one practice, biochemical investigations being requested as often as bacteriological investigations in two of the four practices. The ratio of expected to unexpected results varied among general practitioners; no general practitioner had more unexpected results and the range of ratios was similar for full time and part time general practitioners and for trainees. The proportion of patients with abnormalities uncovered by each practice increased disproportionately as the use of investigations increased, supporting a higher rather than lower rate of investigation among general practitioners. Compared with the results of other studies the use of the radiological facilities available was low. X ray examinations of the skeleton were requested more than chest and contrast media examinations by three of the four practices. Most x ray examinations were used to exclude rather than confirm abnormality by all the practices, with over 85% of results confirming the general practitioner''s initial diagnosis.     

Rectal examination in general practice.

OBJECTIVE--To investigate factors influencing a general practitioner''s decision to do a rectal examination in patients with anorectal or urinary symptoms. DESIGN--Postal questionnaire survey. SETTING--General practices in inner London and Devon. SUBJECTS--859 General practitioners, 609 (71%) of whom returned the questionnaire. MAIN OUTCOME MEASURES--Number of rectal examinations done each month; the indication score, derived from answers to a question asking whether the respondent would do a rectal examination for various symptoms; and the confidence score, which indicated the respondent''s confidence in the diagnosis made on rectal examination. RESULTS--279 General practitioners did five or fewer rectal examinations each month and 96 did more than 10 each month. Factors significantly associated with doing fewer rectal examinations were a small partnership and being a female general practitioner, and the expectation that the examination would be repeated. Lack of time in the surgery, and a waiting time of less than two weeks for an urgent outpatient appointment were also important. General practitioners were deterred from doing rectal examinations by reluctance of the patient (278), the expectation that the examination would be repeated (141), and lack of time (123) or a chaperone (39). Confidence in diagnosis was significantly associated with doing more rectal examinations, the perception of having been well taught to do a rectal examination at medical school, and being a male general practitioner. CONCLUSIONS--Factors other than clinical judgment influence the frequency of rectal examination in general practice. Rectal examination may become commoner with the trend towards larger group practices and if diagnostic confidence is increased and greater emphasis put on rectal examination in undergraduate and postgraduate teaching.     

Long-term digoxin treatment in general practice.

A questionnaire was sent to several general practitioners and specialists in an attempt to obtain a consensus on standards of care for patients receiving long-term digoxin treatment. The consultants'' suggested standards were slightly more stringent than those of the general practitioners. The records of 42 patients taking digoxin under the care of two general practitioners were studied to see how far their actual care matched up to the suggested standards. The models of management proposed by these patients'' doctors were only slightly different from those suggested by other practitioners, but measured against these models the patients'' care was in some cases inadequate. Nevertheless, there was little relationship between the recorded levels of care and the health of the patient, and it may have been the standard of recording rather than the care that was inadequate. Measuring plasma digoxin levels in these patients proved to be of little value. Medical audit is thus a useful tool in helping the general practitioner to review his work and improve his knowledge, but it may not be a practical or true way of measuring the quality of care.     

Consultations in general practice: a comparison of patients' and doctors' satisfaction.

OBJECTIVE--To provide an objective means of assessing patients'' and doctors'' satisfaction with a consultation. DESIGN--Questionnaire study of patients and general practitioners after consultations. SETTING--Urban general practice. SUBJECTS--250 Patients attending consecutive consultations conducted by five general practitioners. MAIN OUTCOME MEASURE--Identification of deficiencies within a consultation as perceived by both doctors and patients. RESULTS--The doctor''s and patient''s questionnaires for each consultation were matched and the results analysed on a group basis. The response rate for individual questions was high (81-89%). The doctors and patients significantly disagreed about the doctors'' ability to assess and put patients at ease, to offer explanations and advice on treatment, and to allow expression of emotional feelings and about the overall benefit that the patients gained from the consultation. In all cases of disagreement the doctor had a more negative view of the consultation than the patient. CONCLUSIONS--The results of giving structured questionnaires on consultations to both patients and doctors could be a useful teaching tool for established doctors or those in training to improve the quality and sensitivity of care they provide.     

Sigmoidoscopy/proctoscopy service with open access to general practitioners.

Many hospitals now offer barium enema examinations to general practitioners on an open access basis, so bypassing the traditional sequence of first carrying out a sigmoidoscopy. An open access sigmoidoscopy/proctoscopy service was therefore opened with requests for a barium enema being denied unless preceded by sigmoidoscopy. During the first three and a half years 1458 patients referred direct from their general practitioners were examined using a rigid sigmoidoscope. Patients were also examined with a proctoscope if thought appropriate. After the first year of the service a subsequent examination with a fibreoptic sigmoidoscope was also carried out if the presenting symptom was bleeding for which no cause could be found with the rigid instruments. A total of 516 abnormalities were found to account for symptoms in 506 patients giving a diagnostic rate of 35%. The most common lesion was piles (307 cases). Other relatively common disorders included inflammatory bowel disease (107 cases), benign tumours (44), and malignant tumours (38). Of 41 patients subsequently undergoing fibreoptic sigmoidoscopy a cause for the bleeding was found in 32, the most common being a malignant tumour (16). Most general practitioners in the district used the service and a questionnaire survey indicated that most found it very helpful. Requests from general practitioners for a barium enema fell substantially over the period.     

Dyspepsia: is a trial of therapy appropriate?

Dyspepsia is a common, benign condition that may be distinguished from gastroesophageal reflux, irritable bowel syndrome and pancreatobiliary, coronary or musculoskeletal disease by a careful history and physical examination. However, the presence or absence of a peptic ulcer in dyspepsia can be determined only by an endoscopic examination or a barium-contrast radiograph. Although the American College of Physicians has recommended trying drug therapy for patients with dyspepsia before diagnostic tests are done, new data support early diagnosis. Although therapy is initially cheaper than endoscopic examination, over a year the costs even out because most patients with dyspepsia eventually need an endoscopic examination, and many patients with nonulcer dyspepsia are given medication unnecessarily. Endoscopic examination, if available to general practitioners, is the most cost-effective approach to dyspepsia. An approach that does not include endoscopy lacks the opportunity to offer patients convincing reassurance that their illness is not serious, which is arguably the most important treatment in cases of nonulcer dyspepsia. Studies supporting the use of endoscopic examination predate the treatment of peptic ulcers with antibiotics, which makes an initial endoscopic examination to determine whether the patient has an ulcer even more important.

Should general practitioners call patients by their first names?

OBJECTIVE--To assess the acceptability to patients of the use of patients'' first names by doctors and doctors'' first names by patients in general practice. DESIGN--An administered questionnaire survey. SETTING--5 General practices in Lothian. PATIENTS--475 Patients consulting 30 general practitioners. MAIN OUTCOME MEASURE--Response by patients to questionnaire on attitude to use of first names. RESULTS--Most of the patients either liked (223) or did not mind (175) being called by their first names. Only 77 disliked it, most of whom were aged over 65. Most patients (324) did not, however, want to call the doctor by his or her first name. CONCLUSIONS--General practitioners should consider using patients'' first names more often, particularly with younger patients.     

Cost effectiveness of magnetic resonance imaging in the neurosciences.

OBJECTIVES--To measure, in a service setting, the effect of magnetic resonance imaging on diagnosis, diagnostic certainty, and patient management in the neurosciences; to measure the cost per patient scanned; to estimate the marginal cost of imaging and compare this with its diagnostic impact; to measure changes in patients'' quality of life; and to record the diagnostic pathway leading to magnetic resonance imaging. DESIGN--Controlled observational study using questionnaires on diagnosis and patient management before and after imaging. Detailed costing study. Quality of life questionnaires at the time of imaging and six months later. Diagnostic pathways extracted from medical records for a representative sample. SETTING--Regional superconducting 1.5 T magnetic resonance service. SUBJECTS--782 consecutive neuroscience patients referred by consultants for magnetic resonance imaging during June 1988-9; diagnostic pathways recorded for 158 cases. MAIN OUTCOME MEASURES--Costs of magnetic resonance imaging and preliminary investigations; changes in planned management and resulting savings; changes in principal diagnosis and diagnostic certainty; changes in patients'' quality of life. RESULTS--Average cost of magnetic resonance imaging was estimated at 206.20/patient pounds (throughput 2250 patients/year, 1989-90 prices including contrast and upgrading). Before magnetic resonance imaging diagnostic procedures cost 164.40/patient pounds (including inpatient stays). Management changed after imaging in 208 (27%) cases; saving an estimated 80.90/patient pounds. Confidence in planned management increased in a further 226 (29%) referrals. Consultants'' principal diagnosis changed in 159 of 782 (20%) referrals; marginal cost per diagnostic change was 626 pounds. Confidence in diagnosis increased in 236 (30%) referrals. No improvement in patients'' quality of life at six month assessment. CONCLUSIONS--Any improvement in diagnosis with magnetic resonance imaging is achieved at a higher cost. Techniques for monitoring the cost effectiveness of this technology need to be developed.     

Palliative care: views of patients and their families.

OBJECTIVE--To investigate the current problems and needs of terminally ill cancer patients and their family members, and to discover their views of hospital, community, and support team services. DESIGN--Prospective study of patients and families by questionnaire interviews in the patients'' homes. SETTING--Inner London and north Kent (London suburbs). SUBJECTS--65 Patients, each with a member of their family or a career. MAIN OUTCOME MEASURES--Ratings of eight current problems and ratings and comments on three services-hospital doctors and nurses, general practitioners and district nurses, and the support team staff-obtained after a minimum of two weeks'' care from palliative care support teams. RESULTS--Effect of anxiety on the patient''s nearest career. and symptom control were rated as the most severe current problems by both patients and families; a few patients and families identified other severe problems. Families'' ratings of pain control, symptom control, and effect of anxiety on the patient were significantly worse than the patients'' ratings (p less than 0.05). Support teams received the most praise, being rated by 58 (89%) patients and 59 (91%) of family members as good as excellent. General practitioners and district nurses were rated good or excellent by 46 (71%) patients and 46 (71%) family members, but six (9%) in each group rated the service as poor or very bad, and ratings in the inner London district were significantly worse than those in the outer London district. Hospital doctors and nurses were rated good or excellent by 22 (34%) patients and 35 (54%) of family members, and 14 (22%) patients and 15 (23%) family members rated this service as poor or very bad. Negative comments referred to communication (especially at diagnosis), coordination of services, the attitude of the doctor, delays in diagnosis, and difficulties in getting doctors to visit at home. Family members were more satisfied with the services than were patients. CONCLUSIONS--Palliative care needs to include both the patient and family because the needs of the family may exceed those of the patient. Support teams and some hospital and community doctors and nurses met the perceived needs of dying patients and families, but better education and organisation of services are needed.     

Measuring outcomes in primary care: a patient generated measure,MYMOP, compared with the SF-36 health survey.

OBJECTIVE--To assess the sensitivity to within person change over time of an outcome measure for practitioners in primary care that is applicable to a wide range of illness. DESIGN--Comparison of a new patient generated instrument, the measure yourself medical outcome profile (MYMOP), with the SF-36 health profile and a five point change score; all scales were completed during the consultation with'' practitioners and repeated after four weeks. 103 patients were followed up for 16 weeks and their results charted; seven practitioners were interviewed. SETTING--Established practice of the four NHS general practitioners and four of the private complementary practitioners working in one medical centre. SUBJECTS--Systematic sample of 218 patients from general practice and all 47 patients of complementary practitioners; patients had had symptoms for more than seven days. OUTCOME MEASURES--Standardised response mean and index of responsiveness; view of practitioners. RESULTS--The index of responsiveness, relating to the minimal clinically important difference, was high for MYMOP: 1.4 for the first symptom, 1.33 for activity, and 0.85 for the profile compared with < 0.45 for SF-36. MYMOP''s validity was supported by significant correlation between the change score and the change in the MYMOP score and the ability of this instrument to detect more improvement in acute than in chronic conditions. Practitioners found that MYMOP was practical and applicable to all patients with symptoms and that its use increased their awareness of patients'' priorities. CONCLUSION--MYMOP shows promise as an outcome measure for primary care and for complementary treatment. It is more sensitive to change than the SF-36 and has the added bonus of improving patient-practitioner communication.     

Screening for carcinoma of the prostate by digital rectal examination in a randomly selected population.

OBJECTIVE--To study the acceptability, costs, psychosocial consequences, and organisation of screening for carcinoma of the prostate. DESIGN--A randomly selected population was personally invited for digital rectal examination by a urologist and a general practitioner. Further examinations were performed if induration was felt. Each man completed a questionnaire on his response to the examination. SETTING--General practices in the area of Norrköping. PATIENTS--1494 Men aged 50-69 randomly selected from a population of 9026. MAIN OUTCOME MEASURE--Prostates having a firm nodular consistency. RESULTS--Carcinoma of the prostate was suspected in 45 of 1163 patients examined; in 10 by the general practitioners, in 10 by the urologists, and in 25 by both. Forty four men had a fine needle aspiration biopsy, and carcinomas were found in 13 cases. Of these, one had been suspected by the general practitioner, four by urologists, and eight by both. The cost for each man was 11.60 pounds, and the cost for each case of carcinoma detected and treated by potentially curative methods was 2477 pounds. Of the 13 men with carcinoma, 10 underwent radical prostatectomy and one radiotherapy. One man had advanced disease and was given endocrine treatment, another was not treated. Only 193 men felt distress during the initial examination. Of the 44 men who had an aspiration biopsy, 25 experienced anxiety. CONCLUSIONS--Screening for carcinoma of the prostate by a urologist or a general practitioner using digital rectal examination is a cost effective method of early diagnosis. Whether such screening leads to prolonged survival, however, remains doubtful.
