A kinematic and kinetic analysis of the sit-to-stand transfer using an ejector chair: implications for elderly rheumatoid arthritic patients.

Twelve elderly female rheumatoid arthritis patients (mean age = 65.5 +/- 8.6 yr) were assessed rising from an instrumented Eser Ejector chair under four conditions: high seat (540 mm), low seat (450 mm), with and without the ejector mechanism operating. Sagittal plane motion, ground reaction forces, and vertical chair arm rest forces were recorded during each trial with the signals synchronised at initial subject head movement. When rising from a high seat, subjects displayed significantly (p < 0.05) greater time to seat off; greater trunk, knee and ankle angles at seat off; increased ankle angular displacement; decreased knee angular displacement; and decreased total net and normalised arm rest forces compared to rising from a low seat. When rising using the ejector mechanism, time to seat off and trunk and knee angle at seat off significantly increased, whereas trunk and knee angular displacement, and total net and normalised arm rest forces significantly decreased compared to rising unassisted. Regardless of seat height or ejector mechanism use, there were no significant differences in the peak, or time to peak horizontal velocity of the subjects' total body centre of mass, or net knee and ankle moments. It was concluded that increased seat height and use of the ejector mechanism facilitated sit-to-stand transfers performed by elderly female rheumatoid arthritic patients. However, using the ejector chair may be preferred by these patients compared to merely raising seat height because it does not necessitate the use of a footstool, a possible obstacle contributing to falls.

The UMDS MSc in general practice: attainment of intended outcomes.

BACKGROUND: The United Medical and Dental School's (UMDS's) MSc in general practice is one of the longest running courses of its kind. Although descriptive accounts of such courses have been published, little is known about their outcomes. AIM: To measure the extent to which graduates feel they have personally achieved 16 intended outcomes derived from the course objectives, and to record current academic activities, particularly teaching and research. METHOD: A postal questionnaire to graduates of the UMDS MSc in General Practice. RESULTS: The response rate was 93%. Of the 71 responders, 23 have gone on to register for or complete other degrees or diplomas. Over two-thirds of responders had an academic commitment following the MSc. Two-thirds were currently engaged in research and over half reported having had work accepted for publication. The majority of graduates confirmed the attainment of all 16 outcomes, although outcomes related to personal achievements were endorsed more strongly than those related to service delivery. CONCLUSION: UMDS graduates are making a significant contribution to their discipline and are unanimous in describing the course as an important event in their personal development. As a result of this study, the course organizers are seeking to increase the links between academic study and everyday practice.

Why do some patients not cash their prescriptions?

BACKGROUND: A small number of studies have used different methodologies to measure primary non-compliance, but they have not established the reasons for patients not cashing their prescriptions. It has been suggested that the number of uncashed prescriptions is a measure of the quality of doctor-patient communication, but this hypothesis remains untested. AIM: To establish the feasibility of obtaining data on a sensitive subject from patients by interview and to seek patients' reasons for not cashing prescriptions using qualitative data. METHOD: Questionnaire administered to 1000 consecutive patients attending surgery, followed by interview with those patients who indicated that they had not cashed the index prescription. RESULTS: The response rate was 93.5%. Twenty-two patients were included in the study. There was wide variation in the number of uncashed prescriptions issued by each doctor (1-13). A total of nine out of 22 patients reported that their medication was cheaper over the counter and obtained it in this way; 13 out of 22 did not obtain their medication. Five patients indicated that cost was a factor in not obtaining their medication. Other factors included the doctor's permission not to cash the prescription, poor understanding of the illness, and the wish to maintain control. CONCLUSION: It is feasible to ask patients about aspects of their behaviour that may indicate, or cause, difficulties in the doctor-patient relationship. Prescribing behaviour varies widely between doctors and, although cost is a factor in determining whether a prescription will be cashed, other variables, such as the patient's desire to maintain control over the illness, may be more important.

The influence of patients' hopes of receiving a prescription on doctors' perceptions and the decision to prescribe: a questionnaire survey.

OBJECTIVES: To measure patients' expectations of receiving prescriptions and general practitioners' perceptions of these expectations and to determine the factors most closely associated with the decision to prescribe. DESIGN: Questionnaires were completed by patients waiting to see their general practitioners, and by their doctors immediately after the consultations. SETTING: Four non-fundholding groups practices in southeast London. SUBJECTS: 544 unselected patients consulting 15 general practitioners. MAIN OUTCOME MEASURES: Doctor's perceptions of patients' expectations; doctors' decisions to prescribe. RESULTS: 67% (354/526) of patients hoped for a prescription; doctors perceived that 56% (305/542) of patients wanted prescriptions; and doctors wrote prescriptions in 59% (321/543) of consultations. Despite the close agreement between patients' hopes and doctors' perceptions, 25% (89/353) of patients hoped for a prescription but did not receive one. In 22% (68/313) of consultations in which prescriptions were written, they were not strictly indicated on purely medical grounds, and in only 66% (202/306) of consultations in which prescriptions were written were they both indicated and hoped for. Doctors' perceptions of patients' expectations were the strongest predictor of the decision to prescribe, but the final regression model also included patients' hopes and ethnic group, and the doctor's feeling of being pressurised. CONCLUSIONS: In an area of low prescribing and high expectations the decision to prescribe was closely related to actual and perceived expectations, but the latter was the more significant influence.

Influence of patients' expectations on antibiotic management of acute lower respiratory tract illness in general practice: questionnaire study.

OBJECTIVE: To assess patients' views and expectations when they consult their general practitioner with acute lower respiratory symptoms and the influence these have on management. DESIGN: General practitioners studied consecutive, previously well adults and recorded clinical data, the certainty regarding their prescribing decision, and the influence of non-clinical factors on that decision. Patients completed a questionnaire at home after the consultation. SETTING: 76 doctors from suburban, inner city, and rural practices. SUBJECTS: 1014 eligible patients entered; 787 (78%) returned the questionnaire. MAIN OUTCOME MEASURES: The views of the patient, the views of and antibiotic prescription by the doctor. RESULTS: Most patients thought that their symptoms were caused by an infection (662) and that antibiotics would help (656) and had both wanted (564) and expected (561) such a prescription. 146 requested an antibiotic, 587 received one. Of the 643 patients who thought they had an infection, 582 wanted an antibiotic and thought it would help. Severity of symptoms did not relate to wanting antibiotics. For those prescribed antibiotics, their doctor thought they were definitely indicated in only 116 cases and not indicated in 126. Patient pressure most commonly influenced the decision to prescribe even when the doctor thought antibiotics were not indicated. Doctors considered antibiotics definitely indicated in only 1% of the group in whom patient pressure influenced the prescribing decision. Patients who did not receive an antibiotic that they wanted were much more likely to express dissatisfaction. Dissatisfied patients reconsulted for the same symptoms twice as often as satisfied patients. CONCLUSION: Patients presenting with acute lower respiratory symptoms often believe that infection is the problem and antibiotics the answer. Patients' expectations have a significant influence on prescribing, even when their doctor judges that antibiotics are not indicated.

Decision-making and hormone replacement therapy: a qualitative analysis.

Biomedical discourse dominates the research literature and media accounts of menopause. Middle aged women are increasingly faced with decisions about hormone replacement therapy (HRT) in the context of differing constructions of menopause and often inconclusive information. There is an apparent discrepancy between the beneficial claims made for HRT in the medical literature and the numbers of women who use it in the U.K. An educational approach has been advocated which assumes that with adequate information more women will take and adhere to HRT. Middle aged women's own views and opinions about medication, health and menopause have been relatively neglected. The extent to which women use medical discourse in discussions of menopause and the extent to which menopause has become "medicalized" remain unclear. This is a descriptive study using in-depth interviews and a qualitative methodology to investigate women's accounts of their decisions relating to HRT use. Ninety-three 50 year old women were recruited from the age/sex register of a North London general practice; 45 women agreed to take part. Three main themes were identified in the women's accounts of their decisions: (1) the presence or absence of troublesome vasomotor symptoms, (2) doctors' views and advice, and (3) views toward menopause and medication. There was a general preference not to take medication, particularly for menopause, which was seen as a natural process unless severe symptoms were present. Women appeared to be considering different criteria from health professionals when making decisions about HRT. Whether these accounts are voiced in a medical consultation will partly depend upon the doctor's beliefs and communication skills as well as the assertiveness of the woman herself.

General practitioners' views on the over-the-counter availability of H2-antagonists.

BACKGROUND: In recent years there has been a trend towards increasing the number of drugs that are available over the counter (OTC) without prescription. Simultaneously, community pharmacists have been encouraged to develop and extend their role. General practitioners (GPs) have been shown to have some reservations about these developments. A group of drugs widely used in general practice, the H2-antagonists, have recently become available OTC. AIM: To examine GPs' attitudes towards community pharmacists dispensing H2-antagonists over the counter (OTC) without prescription. METHOD: Postal questionnaire to a sample of GPs from inner and outer London, Surrey, Kent, Hampshire, Northumberland, Newcastle upon Tyne and Leicestershire. RESULTS: Of 850 questionnaires sent, 515 were returned, an overall response rate of 60.5%. Fifty four per cent of respondents agreed that cimetidine should be available over the counter for dyspepsia in adults under 45 years not responsive to antacids. Ninety per cent of respondents were aware that H2-antagonists had been deregulated. Most general practitioners learned about the deregulation from professional journals. Very few GPs stated they had changed their prescribing practice since H2-antagonists became available OTC. The high cost to the patient of the OTC product was the most frequently mentioned reason why respondents did not encourage their patients to switch from prescription to OTC H2-antagonists. Worries and concerns regarding the OTC availability of H2-antagonists included masking serious conditions, missed diagnosis, loss of control by the GP and the potential for inappropriate use by patients. CONCLUSIONS: Since 1990, there has been a large increase in GPs support for the OTC availability of cimetidine. However, according to their stated behaviour, the reclassification of H2-antagonists does not seem to have changed GPs' prescribing practice, and few appear to be recommending that their patients buy them over the counter.

Respecting the autonomy of cancer patients when talking with their families: qualitative analysis of semistructured interviews with patients.

OBJECTIVE: To discover cancer patients' views about disclosure of information to their family, their family's influence over the information given them, and their preferences for doctors' behaviour if they and their family disagree, as a complement to applied ethical theory. DESIGN: Semistructured interviews followed by qualitative content analysis. SETTING: Mainly urban British general practice. SUBJECTS: 30 patients in whom cancer, excluding basal and squamous cell skin carcinomas, was diagnosed 1-7 years earlier. RESULTS: All subjects wished doctors to respect their views rather than those of their family, should they differ. With their consent, subjects favoured close family receiving information about their illness, all but one mentioning advantage to their family. Without such consent, six unconditionally favoured disclosure of information to their family while seven unconditionally opposed disclosure. Seventeen participants restricted their approval for such disclosure to specific circumstances. Only two participants approved of their family influencing the information that they received about their illness; all but seven wished to receive full information, the exceptions relating to information about bad prognosis. CONCLUSIONS: Subjects favoured openness with their family but most rejected unconditional disclosure of information without their consent and their family influencing what information they would be given. They valued respect for their autonomy more highly than beneficence and considered that their own needs took priority over those of their family.

Qualitative interviews in medical research.

Much qualitative research is interview based, and this paper provides an outline of qualitative interview techniques and their application in medical settings. It explains the rationale for these techniques and shows how they can be used to research kinds of questions that are different from those dealt with by quantitative methods. Different types of qualitative interviews are described, and the way in which they differ from clinical consultations is emphasised. Practical guidance for conducting such interviews is given.
