Do general practitioners act consistently in real practice when they meet the same patient twice? Examination of intradoctor variation using standardised (simulated) patients.

OBJECTIVE: To assess the variation within individual general practitioners facing the same problem twice in actual practice under unbiased conditions. DESIGN: General practitioners were consulted during normal surgery hours by a standardised patient portraying a patient with angina pectoris. Six weeks later the same general practitioners were consulted again by a similar standardised patient portraying a similar case. The patients reported on the consultations. SETTING: Trondheim, Norway. SUBJECTS: Of 87 general practitioners invited by letter, 28 (32%) agreed to participate without hesitation; nine others (10%) wanted more information before consenting. From these 24 were selected and visited. MAIN OUTCOME MEASURES: Number of actions undertaken from a guideline in both rounds of consultations. Duration of consultations. RESULTS: The mean (range, interquartile range) guideline score, total score, and duration of consultation were not significantly different between the first and second patient encounters for the group as a whole. For individual doctors the mean (SD) difference was -0.09 (3.36) for the guideline score, 0.30 (8.1) for the total score, and -0.87 (9.01) for consultation time. CONCLUSIONS: The study shows that assessment of performance in real practice for a group of general practitioners is consistent from the first round of consultations to the second round. However, significant variation occurs in performance of individual physicians.     

Ethnic variations in incidence of asthma episodes in England & Wales:national study of 502,482 patients in primary care

Background

Recent studies have demonstrated marked international variations in the prevalence of asthma, but less is known about ethnic variations in asthma epidemiology within individual countries and in particular the impact of migration on risk of developing asthma. Recent within country comparisons have however revealed that despite originating from areas of the world with a low risk for developing asthma, South Asian and Afro-Caribbean people in the UK are significantly (3× and 2× respectively) more likely to be admitted to hospital for asthma related problems than Whites.

Methods

Using data from the Fourth National Study of Morbidity Statistics in General Practice, a one-percent broadly representative prospective cohort study of consultations in general practice, we investigated ethnic variations in incident asthma consultations (defined as new or first consultations), and compared consultation rates between those born inside and outside the UK (migrant status). Logistic regression models were used to examine the combined effects of ethnicity and migration on asthma incident consultations.

Results

Results showed significantly lower new/first asthma consultation rates for Whites than for each of the ethnic minority groups studied (mean age-adjusted consultation rates per 1000 patient-years: Whites 26.4 (95%CI 26.4, 26.4); South Asians 30.4 (95%CI 30.3, 30.5); Afro-Caribbeans 35.1 (95%CI 34.9, 35.3); and Others 27.8 (27.7, 28.0). Within each of these ethnic groups, those born outside of the UK showed consistently lower rates of incident asthma consultations. Modelling the combined effects of ethnic and migrant status revealed that UK-born South Asians and Afro-Caribbeans experienced comparable risks for incident GP consultations for asthma to UK-born Whites. Non-UK born Whites however experienced reduced risks (adjusted OR 0.82, 95%CI 0.69, 0.97) whilst non-UK born South Asians experienced increased risks (adjusted OR 1.33, 95%CI 1.04, 1.70) compared to UK-born Whites.

Conclusion

These findings strongly suggest that ethnicity and migration have significant and independent effects on asthma incidence. The known poorer asthma outcomes in UK South Asians and Afro-Caribbeans may in part be explained by the offspring of migrants experiencing an increased risk of developing asthma when compared to UK-born Whites. This is the first study to find heterogeneity for incident asthma consultations in Whites by migrant status.     

Ethnic differences in general practitioner consultations.

OBJECTIVE--To examine the levels of general practitioner consultations among the different ethnic groups resident in Britain. DESIGN--The study was based on the British general household surveys of 1983-5 and included 63,966 people aged 0-64. Odds ratios were derived for consultation by ethnic group by using logistic regression analysis adjusting for age and socioeconomic group. SETTING--The results relate to people living in private households in England, Scotland, and Wales. RESULTS--After adjustment for age and socioeconomic class, consultation among adults aged 16-64 was highest among people of Pakistani origin with odds ratios of 2.82 (95% confidence interval 1.86 to 4.28) for men and 1.85 (1.22 to 2.81) for women. Significantly higher consultations were also seen for men of West Indian and Indian origin (odds ratios 1.65 and 1.53 respectively). Ethnic differences were greatest at ages 45-64, when consultation rates in people of Pakistani, Indian, and West Indian origin were much higher in both sexes compared with white people. CONCLUSIONS--The ethnic composition of inner cities is likely to influence the workload and case mix of general practitioners working in these areas.     

Influence of patient characteristics on test ordering in general practice.

Information regarding all consultations was collected in seven general practices for one year. From these data we report on the use of laboratory tests and its association with patient characteristics--including social class, age, sex, and diagnosis--and with which doctor was consulted. Most of the requests were for technically simple tests of low cost. There was a noticeable variation in the use of tests with regard to all patient characteristics. Diagnosis, identity of doctor, age of patient, and social class were each shown by multivariate techniques to be independently related to use of tests. Whereas fewer tests were used per consultation for social classes III-V compared with other social classes, more were used per patient per year for these same groups, reflecting in part the higher consultation rates of social classes III-V. Variation in diagnoses fully accounted for the greater test ordering for women. Nearly two thirds of all tests were ordered for 10% of all patients who consulted and 7% of all registered patients. The results of our analysis suggest that this concentration is determined primarily by those patient characteristics most indicative of medical need and by which doctor is providing care.     

Appropriateness,Reasons and Independent Predictors of Consultations in the Emergency Department (ED) of a Dutch Tertiary Care Center: A Prospective Cohort Study

Objective

Consultations occur frequently in the emergency department (ED) of tertiary care centres and pose a threat for patient safety as they contribute to ED lengths of stay (LOS) and overcrowding. The aim of this study was to investigate reasons and appropriateness of consultations, and the relative impact of specialty and patient characteristics on the probability of a consultation, because this could help to improve efficiency of ED patient care.

Methods

This prospective cohort study included ED patients presenting to a Dutch tertiary care centre in a setting where ED physicians mostly treat self-referred and undifferentiated patients and other specialists treat referred patients. Consultations were defined as appropriate if the reason of consultation corresponded with the final advice, conclusion or policy of the consulted specialty. Multivariable logistic regression analysis was used to assess the relative contribution of specialty and patient characteristics on consultation.

Results

In the 344 (24% (95% CI 22 to 26%)) of the 1434 inclusions another specialty was consulted, resulting in a 55% increase of ED LOS. ED physicians more often consulted another specialty with a corrected odds ratio (OR) of 5.6 (4.0 to 7.8), mostly because consultations were mandatory in case of hospitalization or outpatient follow-up. Limited expertise of ED physicians was the reason for consultation in 7% (5 to 9%). The appropriateness of consultations was 84% (81 to 88%), similar between ED physicians and other specialists (P = 0.949). The patient characteristics age, comorbidity, and triage category and complaint predicted consultation.

Conclusion

In a Dutch tertiary care centre another specialty was consulted in 24% of the patients, mostly for an appropriate reason, and rarely because of lack of expertise. The impact of consultations on ED LOS could be reduced if mandatory consultations are abolished and predictors of a consultation are used to facilitate timely consultation.     

Reactions of patients to video recording of consultations in general practice.

The potential value of video recording for examining medical consultations depends on the extent to which recordings are representative of unfilmed consultations. This paper examines the views of 295 patients in two general practices whose consultations were filmed and compares them with the views of a control group of 185 patients. Most of those who were filmed reported that the consultation was not directly affected, and no overall effect of filming was discovered when patients rated their stress after the consultations, their rapport with the doctor, or other aspects of the consultation. At one practice, however, filming was significantly associated with lower ratings of rapport between doctor and patient among those patients who reported some direct effect of filming. Patient refusal rates from other studies are also examined and shown to vary systematically--the more opportunity patients are given to decline the more likely they are to take it. Consideration of doctors'' responses to being filmed would usefully complement the emphasis on the views of patients.     

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.     

General practice consultations: is there any point in being positive?

A group of 200 patients who presented in general practice with symptoms but no abnormal physical signs and in whom no definite diagnosis was made were randomly selected for one of four consultations: a consultation conducted in a "positive manner," with and without treatment, and a consultation conducted in a "non-positive manner," called a negative consultation, with and without treatment. Two weeks after consultation there was a significant difference in patient satisfaction between the positive and negative groups but not between the treated and untreated groups. Similarly, 64% of those receiving a positive consultation got better, compared with 39% of those who received a negative consultation (p = 0.001) and 53% of those treated got better compared with 50% of those not treated (p = 0.5).     

Evaluating care of patients reporting pain in fundholding practices.

OBJECTIVE--To compare quality of care between 1990 and 1992 in patients with self diagnosed joint pain. DESIGN--Questionnaire and record based study. SUBJECTS--Patients identified at consecutive consultations during two weeks in 1990, 1991, and 1992. SETTING--Six practice groups in pilot fundholding scheme in Scotland. MAIN OUTCOME MEASURES--Length of consultation; numbers referred or investigated or prescribed drugs; responses to questions about enablement and satisfaction. RESULTS--About 15% of patients consulted with joint pain each year. 25% (316) of them had social problems in 1990 and 37% (370) in 1992; about a fifth wanted to discuss their social problems. Social problems were associated with a raised general health questionnaire score. The mean length of consultation for patients with pain was 7.6 min in 1990 and 7.7 min in 1992. Patients wishing to discuss social problems received longer consultations (8.5 min 1990; 10.4 min 1992); but other patients with social problems received shorter consultations (7.4 min; 7.2 min). The level of prescribing was stable but the proportion of patients having investigations or attending hospital fell significantly from 1990 to 1992 (31% to 24%; 31% to 13% respectively). Fewer patients responded "much better" to six questions about enablement in 1992 than in 1990. Enablement was better after longer than shorter consultations for patients with social problems. CONCLUSIONS--Quality of care for patients with pain has been broadly maintained in terms of consultation times. The effects of lower rates of investigation and referral need to be investigated further.     

Effect of computer use in the consultation on the delivery of care.

The effects of the use of a computer on the delivery of care in consultations in general practice were examined. In this trial a computer system provided for the review and update of patients'' medical histories, notes on doctor-patient contacts, and information on repeat prescribing. Thirty consultations in which the computer system was used and 30 consultations in which no computer was used were matched individually for the doctor consulted, the sex and age of the patient, and the presenting problem(s). Six independent general practitioners blind rated each consultation for the standard of care attained. A minor negative effect of computer use on the doctors'' clinical performance was found. We suggest, however, that this small effect would disappear if a computer system was used routinely.     

Deprivation and general practitioner workload.

OBJECTIVES--To examine general practitioner consultations by demographic and socioeconomic variables and to derive a method of measuring the impact of relative deprivation on general practitioner workload. DESIGN--The study was based on general practitioner consultations reported in the general household surveys of 1983-7, covering a sample of 129,987 individuals in Great Britain. Odds ratios for general practitioner consultations were obtained for selected variables among children (0-15 years), men (16-64), women (16-64), and elderly people (greater than or equal to 65). These were then used to derive deprivation indices specific to electoral wards for use in general practice. SETTING--Great Britain, with particular findings illustrated by English electoral wards and the conurbations of London, Manchester, Merseyside, and the West Midlands. RESULTS--Council tenure increased the likelihood of consultation significantly in all four groups. Odds ratios were raised in children, men, and women with no access to a car. Birth in the New Commonwealth or Pakistan yielded high odds ratios in men, women, and elderly people but not in children. Marginally increased consultation rates were evident in the manual socioeconomic groups in women, elderly people, and children with a single parent mother. The deprivation indices for general practice derived using these odds ratios varied substantially among English electoral wards with, for example, anticipated general practitioner consultations in the electoral ward of Hulme, Manchester, being 24% higher than the average ward in England as a result of local attributes, and consultations in the Cheam South ward of Sutton, London, 11% lower than average. CONCLUSION--This deprivation index for general practice overcomes several shortcomings expressed about the underprivileged area score, which has been adopted in the 1990 contract as a basis for allocating deprivation supplements to general practitioners. The proposed index can be applied nationwide.     

Child consultation patterns in general practice comparing "high" and "low" consulting families.

All children''s consultations with their general practitioner over a 12 month period in a small urban practice were analysed. Overall consultation rates ranged from 2.2 per child a year for 8 to 11 year olds, to 6.8 for those under 2. Families were grouped according to their average rate of new consultation for children, standardised for age. Families with higher consulting rates scored higher on an index of economic disadvantage, with mothers who scored higher on a test of "tendency to consult" and who were less educated than those in lower consulting families. The presence of any doctor-defined "significant disease" in any child was highly correlated with the family''s consultation rate.     

Effect of distance from surgery on consultation rates in an urban practice.

Introducing a microcomputer into a general practice provides an opportunity to consider how different population groups use the services offered. In a study of the effect that distance has on consultation rates the results showed that patients who lived close to the surgery consulted a third more than those who lived over two and a half miles from the surgery. Further analysis showed that patients who might be expected to have transport difficulties were particularly low users.     

Assessing the consultation: methods of observing trainees in general practice.

We compared two different methods of observing trainees at work in general practice: the traditional one of a senior or training general practitioner sitting in during selected surgeries and the more modern video recording, with the patients'' written consent. Patients who had experienced the presence of a second doctor during the consultation were less likely to show an increase in arousal after their consultations than those who had been recorded on video. Patients who refused consent to be recorded were more highly stressed than those who agreed and showed smaller decreases in stress after consultations. The presence of two doctors generated fewer reductions in stress after the consultation than video recording did, but this was a non-significant trend. The group that was recorded on video did not differ appreciably from a control group in changes in stress or arousal.     

Unemployment and patterns of consultation with the general practitioner.

The relation between unemployment and consultations with the general practitioner was investigated among 13,275 economically active men aged 18-64 by using the British general household surveys. Men who were unemployed but seeking work consulted with doctors significantly more (odds ratio 1.83; 95% confidence interval 1.61 to 2.09) than those in employment, the highest consultation rate being among those who had been out of work for five years or more (odds ratio 2.12; 95% confidence interval 1.12 to 3.78). The high consultation rates persisted even after adjustment for self reported longstanding illness (odds ratio 1.53; 95% confidence interval 1.34 to 1.76). These findings suggest that in areas with high unemployment general practitioner workload is likely to be high.     

An instrument for assessment of videotapes of general practitioners' performance.

OBJECTIVES--To identify those important characteristics of doctors'' and patients'' behaviour that distinguish between "good" and "bad" consultations when viewed on videotape; to use these characteristics to develop a reliable instrument for assessing general practitioners'' performance in their own consultations. DESIGN--Questionnaires completed by patients, general practitioner trainers, and general practitioner trainees. Reliability of draft instrument tested by general practitioner trainers. SETTING--All vocational training schemes for general practice in the Northern region of England. SUBJECTS--First stage: 76 patients in seven groups, 108 general practice trainers in 12 groups, and 122 general practice trainees in 10 groups. Second stage: 85 general practice trainers in 12 groups. MAIN OUTCOME MEASURES--Trainers'' ratings of importance; alpha coefficients of draft instrument by trainee, group, and consultation. RESULTS--6890 characteristics of good and bad consultations were consolidated into a draft assessment instrument consisting of 46 pairs of definitions separated by six point bipolar scales. Nine statement pairs given low importance ratings by trainers were eliminated, reducing the instrument to 37 statement pairs. To test reliability, general practitioner trainers used the instrument to assess three consultations. With the exception of one group of trainers, all alpha coefficients exceeded the acceptable level of 0.80. CONCLUSION--The instrument produced is reliable for assessing general practitioners'' performance in their own consultations.     

Postal survey of patients' satisfaction with a general practice out of hours cooperative.

OBJECTIVE: To assess patients'' satisfaction with out of hours care by a general practice cooperative compared with that by a deputising service. DESIGN: Postal questionnaire survey. SETTING: A general practice cooperative in London and a deputising service operating in an overlapping area. SUBJECTS: Weighted samples of patients receiving telephone advice, a home visit, or attending a primary care centre after contacting either service in an eight week period. MAIN OUTCOME MEASURES: Patients'' overall satisfaction and scores for specific aspects of satisfaction. Satisfaction with telephone advice or attendance at centre compared with home visit. Relation between satisfaction and patient''s age, sex, ethnic group, car ownership, preference for consulting own doctor, and expectation of a visit. RESULTS: The overall response rate was 67% (1555/2312). There was little difference in overall satisfaction between patients contacting the cooperative or the deputising service, but patients contacting the latter were less satisfied with the explanation and advice received and the wait for a visit. There were significant differences between patients in different age and ethnic groups, with white patients and those aged over 60 years being more satisfied. Lower scores for overall satisfaction were reported by patients who received telephone advice, those who would have preferred to see their own doctor or who originally wanted a home visit, and those who waited longer for their consultation. Overall levels of patients'' satisfaction seemed to be lower than previously reported. CONCLUSIONS: There were larger differences in satisfaction between different groups of patients than between different models of organisation for out of hours care. A shift to a service based predominantly on telephone advice may lead to increased patient dissatisfaction.     

Patients' assessment of out of hours care in general practice

A sample of 177 patients drawn from 13 north London practices were interviewed shortly after they had sought help from their practice outside normal surgery hours. Patients were asked to describe the process and outcome of their out of hours call, to comment on specific aspects of the consultation, and to access their overall satisfaction with the encounter.Parents seeking consultations for children were least satisfied with the consultation; those aged over 60 responded most positively. Visits from general practitioners were more acceptable than visits from deputising doctors for patients aged under 60, but for patients aged over 60 visits from general practitioners and deputising doctors were equally acceptable.Monitoring of patients'' views of out of hours consultations is feasible, and the findings of this study suggest that practices should regularly review the organisation of their out of hours care and discuss strategies for minimising conflict in out of hours calls—particularly those concerning children.     

Socioeconomic determinants of rates of consultation in general practice based on fourth national morbidity survey of general practices.

OBJECTIVE--To identify the socioeconomic determinants of consultation rates in general practice. DESIGN--Analysis of data from the fourth national morbidity survey of general practices (MSGP4) including sociodemographic details of individual patients and small area statistics from the 1991 census. Multilevel modelling techniques were used to take account of both individual patient data and small area statistics to relate socioeconomic and health status factors directly to a measure of general practitioner workload. RESULTS--Higher rates of consultations were found in patients who were classified as permanently sick, unemployed (especially those who became unemployed during the study year), living in rented accommodation, from the Indian subcontinent, living with a spouse or partner (women only), children living with two parents (girls only), and living in urban areas, especially those living relatively near the practice. When characteristics of individual patients are known and controlled for the role of "indices of deprivation" is considerably reduced. The effect of individual sociodemographic characteristics were shown to vary between different areas. CONCLUSIONS--Demographic and socioeconomic factors can act as powerful predictors of consultation patterns. Though it will always be necessary to retain some local planning discretion, the sets of coefficients estimated for individual level factors, area level characteristics, and for practice groupings may be sufficient to provide an indicative level of demand for general medical services. Although the problems in using socioeconomic data from individual patients would be substantial, these results are relevant to the development of a resource allocation formula for general practice.
