What is ... a modified essay question?

Medical education is moving to a more problem-orientated basis than was the case formerly. The Modified Essay Question has its origins in this movement, being introduced in the late 1960s as one assessment technique more suited to general practice than other traditional assessment methods. In its original form it is a paper exercise based on an evolving situation presented by a patient in primary care. Experience with the technique in different countries is briefly summarised, and its applications to assessment and to teaching are discussed. Despite shortcomings this method appears to be standing up to the test of time.

Biological variability of 26 clinical chemistry analytes in elderly people.

Analytical, within-subject, and between-subject components of variation were estimated for 26 clinical chemistry analytes from duplicate analyses of 10 specimens collected from 27 healthy elderly subjects over a period of 20 weeks. Within-subject variations were similar to those generated previously by us in younger subjects. We conclude, therefore, that homeostasis is not compromised by age alone, and biological variability does not increase simply with age. All analytes except serum water had marked individuality, showing that conventional population-based reference values are of limited utility. The critical differences required for two results to be significantly (P less than or equal to 0.05) changed are not the same as those that prompt action by clinicians. Although heterogeneity of within-subject variation does exist, we believe that the critical differences generated will be useful in routine clinical decision making.

Diagnosis of occupational dermatitis by general practitioners and employment medical advisors: a pilot study.

This pilot study examined how closely general practitioners and employment medical advisors agreed when jointly investigating occupational dermatitis. The criterion for admitting a patient to the study was dermatitis on one or both hands. This presented most commonly among men aged 41-60 years and women aged 21-40 years. There was some reluctance among general practitioners to take part in the study, probably owing to the medico-legal problems associated with this condition. General practitioners and employment medical advisors were equally likely to attribute a case of dermatitis to occupational factors if the patient was employed in industry; but if the patient was in nonindustrial employment, general practitioners were more likely to consider the possibility of an occupational origin than employment medical advisors. These differences suggest that before initiating a wider study more information is required concerning the trigger mechanisms for dermatitis on the hands in order to reduce the diagnostic variability.

Rheumatic diseases: a general practitioner's view.

Patients with rheumatic complaints are the subject of some 10% of the general practitioner's work. Approximately half of this work is related to the hitherto relatively neglected group of varied soft-tissue conditions, most of which are self-limiting and of a minor nature. Against a background of such diagnostic 'noise', the general practitioner has to remain alert for the fainter 'signal' of serious disease--rheumatic and non-rheumatic--at an early stage. Continuity of care calls on special qualities, behaviours and abilities in the doctor to boost and maintain morale, to coordinate management and to participate in team care. In addition to more traditional therapeutic measures, including analgesics, NSAIDs, disease-modifying drugs and physiotherapy, joint replacement is seen as a significant contribution. There is room for improvement in the structure process and outcomes of delivery of care as it may relate to rheumatic diseases. A simple illustration, based on a general practice audit of gout, is suggested as a possible model by which quality of care could be enhanced at the level of individual patients. While there is not a great deal of scope afforded to the general practitioner in the exercise of primary prevention of the rheumatic diseases, early diagnosis and timely support for carers of patients suffering from chronic rheumatic diseases are areas worth attention. Promotion of self-help is seen as a worthwhile activity in humanitarian and economic terms, though it calls for an appropriate balance to be struck.

Comparison of response rates to a postal questionnaire from a general practice and a research unit.

A postal questionnaire study was carried out in an urban general practice to determine the effect of the introductory letter being sent by the participants' own general practitioner compared with that from a letter sent directly from a research unit. By sequential sampling 409 individuals aged between 40 and 59 were assigned to one of two groups. The people in one group were written to by their own general practitioner and those in the other by a doctor from a research unit. Husbands and wives were paired and were always sent the same letter. A second letter was sent to nonresponders after one month. The response rate to the general practitioner was significantly higher than that to the doctor in the research unit (85% compared with 75%) and differed by age and sex. The results have important implications for other research workers and suggest that general practitioners are in a key position in the conduct of medical and epidemiological research.

Communication skills teaching, learning and assessment.

This paper outlines an introductory course in teaching communication skills to medical students in a preclinical context. The aims of the course, its content and teaching methods are described. Novel features include the active participation of selected patients in teaching and assessment, and the use of a form of role-play named 'listening triads'. The main focus of the paper is assessment, and results are recorded, relating to a class of 114 second-year students during the academic session 1983-84. Assessment of the students' learning was measured by Modified Essay Question (MEQ); students' problems face-to-face with patients were identified by patients, students, and by staff members observing interactions. Problems of fitting these educational assessments into a traditional academic 'certifying' type of assessment remain unresolved at present. This course was found to be acceptable by the preclinical students, and their lack of clinical knowledge did not appear to interfere with their learning. They were enthusiastic about the supervised contact with patients, which appeared to contribute significantly to the way the course was received.

General practitioner's care of the elderly: studies of aspects of workload.

This paper reports trends in the volume and nature of general practitioners' contacts with the elderly patients on their NHS lists in Dundee during the 1970s. It forms part of a larger project involving 32 general practitioners collaborating in a continuing study concerning the introduction of the first health centre in Dundee.During the decade contacts with the elderly increased as a proportion of the general practitioners' total work, broadly commensurate with the increase in Dundee's elderly population. Indirect contacts, mainly reissue of prescriptions for longterm medication, showed a greater proportional increase than direct consultations. Home visiting of the elderly remained relatively constant, while house calls to other age groups declined. Hospital referrals remained a small proportion of the general practitioners' work. Entry into a health centre was not associated with obvious changes in patterns of workload.If more might be done in planning and implementing changes in care of the elderly at general practice level, such changes should be the result of consensus among the professionals concerned, and should take account of the views of recipients of care.

Assessment of the immunization status of practice children under five years of age.

Many professional groups are involved in immunization, and four different immunization records may be kept-the general practice record, the community child health record, the health visitor record and a record retained by the parent. The first three of these sources were examined for the immunization status of children under five years of age in a practice. The health visitor record was the most comprehensive. There was a remarkable improvement in pertussis vaccine acceptance over the four years reviewed but there were gaps in the uptake of measles vaccine.
