Does competence of general practitioners predict their performance? Comparison between examination setting and actual practice.

OBJECTIVE: To study the differences and the relation between what a doctor actually does in daily practice (performance) and what he or she is capable of doing (competence) by using national standards for general practice. DESIGN: General practitioners were consulted by four standardised (simulated) patients portraying four different cases during normal surgery hours. Later the doctors participated in a controlled practice test, for which they were asked to perform to the best of their ability. In the test they saw exactly the same standardised cases but in different patients. The patients reported on the consultations. SETTING: Province of Limburg, the Netherlands. SUBJECTS: 442 general practitioners invited by a letter. 137 (31%) agreed to participate, of whom 36 were selected and visited. MAIN OUTCOME MEASURES: Number of actions taken during the consultations across complaints and for each category of complaint: the competence and performance total scores. Combination of scores with duration of consultations (efficiency-time score). Correlation between scores in the competence and performance part. RESULTS: Mean (SD) total score across complaints for competence was 49% higher than in the performance test (81.8 (11) compared with 54.7 (10.1), p less than 0.0001). The Pearson correlation across complaints between the competence total score and the performance total score of the participating physicians was -0.04 (not significant). When efficiency and consultation time of the consultations were taken into account, the correlation was 0.45 (p less than 0.01). CONCLUSIONS: Assessment of competence under examination circumstances can have predictive value for performance in actual practice only when factors such as efficiency and consultation time are taken into account. Below standard performance of physicians does not necessarily reflect a lack of competence. Performance and competence should be considered as distinct constructs.

A method for introducing standardized (simulated) patients into general practice consultations.

A study has been undertaken to determine whether it is possible for a set of standardized (simulated) patients to visit general practitioners, without being detected, in a health care system where doctors have fixed patient lists. Since sending standardized patients into doctors' offices is a new way to assess the performance of general practitioners; this paper describes in detail the methodology that has been used for visits. The paper looks first at the general preparation for visits and secondly at the specific preparation concerning the fine detail of the individual visit. The method was tested in 156 consultations with 39 general practitioners and in no cases were the standardized patients detected. None of the doctors visited felt offended and all were prepared to cooperate in future studies with standardized patients. It is concluded that the standardized patient method, following the step-by-step procedure described, is feasible in actual practice.

Assessment of the performance of general practitioners by the use of standardized (simulated) patients.

A study was undertaken whereby a set of standardized (simulated) patients visited general practitioners without being detected, in a health care system where doctors had fixed patient lists. Thirty nine general practitioners were each visited during normal surgery hours by four standardized patients who were designed to be indistinguishable from real patients. The objective of the study was to see whether the actual performance of general practitioners, as assessed by standardized patients, met predetermined consensus standards of care for actual practice. The patients presented standardized accounts of headache, diarrhoea, shoulder pain and diabetes. The mean group scores of the doctors on the predefined standards of care for the different complaints ranged from 33 to 68%. The results show that standardized patients may be the method of choice in the assessment of the quality of actual care of doctors. It is hypothesized that the substandard scores of the doctors do not reflect inadequate competence, but are a result of the difference between competence and performance.

Competence and performance: two different concepts in the assessment of quality of medical care.

In the debate about 'what is a competent general practitioner?' little attention has been paid ot the actual practice situation of general practitioners. This paper, based on the 18 most important studies in the literature about medical competence, tries to re-initiate this debate by proposing a clear distinction between 'competence', (what a physician is capable of doing) and 'performance' (what a physician does in his day-to-day practice). With this distinction we looked at whether studies defined both competence and performance, how they dealt with these concepts, what measurement instruments were used and what the conclusions of the studies were. Although it is the common reasoning that competence is a good predictor of performance this concept could not be affirmed. This survey shows that the majority of studies use wrong concepts and come to invalid conclusions. With the empirical distinction between competence and performance however, this paper proposes new directions for the quality assessment of general practitioners.

Do personal computers make doctors less personal?

Ten months after the installation of a computer in a general practice surgery a postal survey (piloted questionnaire) was sent to 390 patients. The patients' views of their relationship with their doctor after the computer was introduced were compared with their view of their relationship before the installation of the computer. More than 96% of the patients (n = 263) stated that contact with their doctor was as easy and as personal as before. Most stated that the computer did not influence the duration of the consultation. Eighty one patients (30%) stated, however, that they thought that their privacy was reduced. Unlike studies of patients' attitudes performed before any actual experience of use of a computer in general practice, this study found that patients have little difficulty in accepting the presence of a computer in the consultation room. Nevertheless, doctors should inform their patients about any connections between their computer and other, external computers to allay fears about a decrease in privacy.

Simulated patients in general practice: a different look at the consultation.

To develop a better empirical basis for developing quality assessment in general practice three simulated patients made appointments with 48 general practitioners during actual surgery hours and collected facts about their performance. The simulated patients were indistinguishable from real patients and presented a standardised story of a symptomatic urinary tract infection. Two months later the same general practitioners received a written simulation about a patient who had the same urinary tract infection and were asked how they would handle this in real practice. Both results were scored against an existing consensus standard. The overall score for both methods did not show any substantial differences. A more differentiated analysis, however, showed that general practitioners performed significantly better with simulated patients. It also showed that general practitioners answering the written simulation performed significantly more unnecessary and superfluous actions. The results of this study show that the use of simulated patients seems to show the efficient performance of general practitioners in practice.
