Assessment of elderly people in general practice. 2. Functional abilities and medical problems.

A random sample of 239 patients aged 75 years and over registered with general practitioners in north and north west London was selected for home assessment to determine the functional abilities and medical problems of this group of patients. Nearly one in five of the patients were incontinent of urine (18.4%), although this was on a daily basis for only 4.1%. Around one in 20 patients were incontinent of faeces (5.9%), yet only one patient had laundry service support. Unassisted mobility outdoors was reported as possible by 81.2% of the patients. Fourteen different types of aids were present in the participants' homes, the commonest being walking sticks, bath aids and stair rails. Only a small proportion of aids seemed to be currently unused. The major functional problems were bathing, housework, shopping, washing and ironing, and cooking main meals, but the level of demand for extra help was low. One in five patients had a hearing aid (19.8%) but for only 30% of these patients was it in continuous use. Polypharmacy was common, with 29.7% of patients taking three or more prescribed medicines. The workload implications of this approach to anticipatory care of elderly people are considerable. In an average practice of 2000 patients with 130 patients aged 75 years and over the primary care team would need over 150 hours of face-to-face contact per year with these patients to fulfil the new contractual obligation and the yield of new information leading to effective medical or social intervention is limited.(ABSTRACT TRUNCATED AT 250 WORDS)

Medical student experience of London general practice teaching attachments.

Forty-eight students kept a log diary of activities during their central London general practice teaching attachments associated with the Department of Primary Health Care of University College and Middlesex School of Medicine. The students each saw on average 96 patients per week, of whom 69% were discussed by the general practitioner with the student after the consultation. Students spent an average of 21.5 hours a week sitting in with the general practitioner. While most of this time was as a passive observer, the students were also able to participate more actively, personally taking histories for a median of 1.25 hours a week and personally examining patients for a median of 1.7 hours a week. During these periods of active involvement each student personally took a mean of 10 short and 2.5 long histories per week and performed a mean of 25.5 short and 1.2 long examinations per week. General practitioners to whom the students were attached spent a mean of 4 hours a week on (patient-oriented) teaching. The tuition was highly rated by the students in terms of both usefulness and stimulation. Students also received a mean of 2.3 hours a week of teaching from other members of the primary health care team, which was somewhat less well received. Areas for improvement were: the relatively few home visits (median of 6 per week) per student; the limited time students spent on self-education (average of 65 minutes per week); and the few practical procedures performed by the students. Students could also be encouraged to play a more active role in examining and interviewing patients.

Screening for cognitive impairment in the elderly using the mini-mental state examination.

The use by non-medical staff of a brief screening instrument (the mini-mental state examination) to detect cognitive impairment among the elderly in primary care is described. Patients aged 75 years and over registered with nine general practices in north and north west London were invited by their general practitioners to take part in the study and 1170 patients participated, a response rate of 90%. The prevalence of possible or probable cognitive impairment (score below 25 on the mini-mental state examination) was 12.8%. Six per cent of patients scored below 19, at which score a high probability of dementia exists, although less than a third of this group had a diagnosis of dementia in their medical records. There was no significant difference between men and women or by social class in the proportion of patients with low scores, but the proportion with dementia rose from 2.5% in those aged 75-79 years to 29.0% among those aged 90 years and over. Under the new general practitioner contract there is a requirement to provide annual services to the elderly, including a 'mental assessment'. In a practice with a list size of 2000 around 130 patients are likely to be aged 75 years and over. Of these around 17 would require further assessment for possible dementia on the basis of results obtained using the mini-mental state examination.

Scheduling lectures in a teaching hospital.

A modelling technique has been devised that can be used to assist in scheduling lectures for medical students in teaching hospitals. The model takes into account the various clinical commitments that are faced by students and the fact that some of these commitments have a fixed timetable while others are relatively flexible. A simple model is framed for the conflict caused by a particular lecture period in terms of the number of commitments which clash. A computer program has been written that produces graphical output illustrating the effects of various scheduling options. The output from the computer program can be used by decision-makers to examine different options for scheduling lectures and also to explore the effects of rescheduling other clinical activities where there is flexibility so to do.

A mathematical model of the development of drug resistance to cancer chemotherapy.

A mathematical model incorporating descriptions of tumour growth kinetics and the effects of cytotoxic chemotherapy on established tumours, is presented. It is shown how models of this kind may be used to investigate the potential of hypothetical chemotherapy strategies, and to identify general principles for successful treatment. The model is intended to be an aid to clinicians designing new chemotherapy programmes for diseases in which progress has been disappointing.
