Comparison of consultation rates in primary care attenders with and without seasonal affective disorder.

BACKGROUND: There is a lack of published information about the consultation patterns of patients with seasonal affective disorder (SAD) in primary care, when compared with non-seasonal controls (NSCs). METHODS: Interview-confirmed SAD cases (n=90) were age- and sex-matched to two controls without significant seasonal morbidity on the Seasonal Pattern Assessment Questionnaire (SPAQ) (non-seasonal controls, NSCs). A comparison of their consultation rates was made using data abstracted from primary care records over 4 years. RESULTS: The monthly rate of general practice consultations for SAD cases was significantly higher than that for NSCs. There was a significant difference in the median number of consultations in winter and autumn between the two groups. The matched multivariate analysis revealed that February and April were the independent months in which cases of SAD had significantly more consultations than NSCs. LIMITATIONS: Optimal diagnostic criteria for SAD have not been determined and our criteria may have been over-inclusive. CONCLUSION: In addition to a marked difference in monthly consultation rates between SAD cases and NSCs, the data demonstrate a difference in the pattern of seasonality of these rates. It is possible that increased frequency of consultation, in particular during the winter months (in patients who score as a case SPAQ), could be used as an indication of SAD in primary care.

Light therapy for seasonal affective disorder in primary care: randomised controlled trial.

BACKGROUND: Studies of light therapy have not been conducted previously in primary care. AIMS: To evaluate light therapy in primary care. METHOD: Fifty-seven participants with seasonal affective disorder were randomly allocated to 4 weeks of bright white or dim red light. Baseline expectations for treatment were assessed. Outcome was assessed with the Structured Interview Guide for the Hamilton Depression Scale, Seasonal Affective Disorder Version. RESULTS: Both groups showed decreases in symptom scores of more than 40%. There were no differences in proportions of responders in either group, regardless of the remission criteria applied, with around 60% (74% white light, 57% red light) meeting broad criteria for response and 31% (30% white light, 33% red light) meeting strict criteria. There were no differences in treatment expectations. CONCLUSIONS: Primary care patients with seasonal affective disorder improve after light therapy, but bright white light is not associated with greater improvements.

Seasonal affective disorder among primary care attenders and a community sample in Aberdeen.

BACKGROUND: There are no large published studies of the prevalence of seasonal affective disorder (SAD) among UK populations. AIM: To determine the prevalence of SAD among patients attending a general practitioner (GP). METHOD: Patients aged 16-64 consulting their GPs in Aberdeen during January were screened with the Seasonal Pattern Assessment Questionnaire (SPAQ). SPAQs were also mailed to 600 matched patients, who had not consulted their GP during January. Surgery attenders who fulfilled SPAQ criteria for SAD were invited for interview to determine whether they met criteria for SAD in DSM-IV and the Structured Interview Guide for the Hamilton Rating Scale for Depression--Seasonal Affective Disorder Version (SIGH-SAD). RESULTS: Of 6161 surgery attenders, 4557 (74%) completed a SPAQ; 442 (9.7%) were SPAQ cases of SAD. Rate of caseness on the SPAQ did not differ between surgery attenders and non-attenders. Of 223 interviewed SPAQ cases of SAD, 91 (41%) also fulfilled DSM-IV and SIGH-SAD criteria. CONCLUSIONS: There is a high prevalence of SAD among patients attending their GPs in January in Aberdeen; this is likely to reflect a similar rate in the community.

A survey of general practitioners in north-east Scotland on practice-based counselling services.

OBJECTIVE: Practice-based counselors have become very numerous in primary care and we sought to elicit the views of general practitioners in north-east Scotland about the present situation and possible developments in practice-based counselling services. DESIGN AND SUBJECTS: A questionnaire was mailed to the 352 general practitioners working in the area covered by Grampian Health Board. RESULTS: There was a 74% response rate: 46% of respondents had access to a practice-based counsellor and of those who did not, two-thirds wanted to acquire one. Larger practices and fundholding practices were more likely to have practice-based counsellors. There was a lack of knowledge about the medico-legal situation when referrals to counsellors were made. Seventy-nine per cent of respondents thought that the need/demand for counselling would increase during the next decade, and a majority considered provision of counselling through mental health teams, with local co-ordination of accreditation, training and supervision, to be desirable. CONCLUSION: Since the efficacy of counselling for mental health problems in primary care has not been established, and provision of counselling in primary care settings continues to increase, there is a need to mount coherent and appropriate research studies. There also appears to be a need for greater integration between primary care and mental health services to generate rational provision of practice-based counselling.

Seasonal affective disorder among primary care consulters in January: prevalence and month by month consultation patterns.

BACKGROUND: Little is known about the prevalence or the consultation patterns of patients with seasonal affective disorder (SAD) in primary care settings. METHODS: Patients aged 16-64 years consulting a general practitioner (G.P.) during a three week period in January were screened with the Seasonal Pattern Assessment Questionnaire (SPAQ). Interview-confirmed cases of SAD (N = 33) were matched by age and sex to controls without seasonal morbidity and primary care consultation patterns were compared over a 5 year period. RESULTS: Of 692 patients screened, 64 (9.3%) satisfied SPAQ criteria for winter SAD. Patients with SAD showed no winter excess of consultations but were high year round consulters, averaging 1.8 times more consultations than controls. CONCLUSIONS: High levels of SAD caseness on the SPAQ were found among patients consulting in primary care during January. Possible explanations for the high non-seasonal consultation patterns among SAD patients include somatisation and diagnostic inaccuracies. LIMITATIONS: Diagnostic criteria for SAD, and the SPAQ in particular, may be over-inclusive. The SPAQ completion rate (about 39% of eligible patients consulting a G.P.) was relatively low. CLINICAL RELEVANCE: Patients with SAD (using SPAQ criteria) commonly consult their G.P.s in winter but frequency, rather than seasonality, of consultation may be a better guide to diagnosing SAD in primary care.

Medical abortion or vacuum aspiration? Two year follow up of a patient preference trial.

OBJECTIVE: To describe and compare health outcomes two years after medical abortion or vacuum aspiration in women recruited into a patient preference trial during 1990 to 1991. DESIGN: Women recruited to the original, partially randomised study were contacted for assessment using a structured interview. SETTING: Grampian region of Scotland, UK. PARTICIPANTS: One hundred and forty women who had participated in a partially randomised study of first trimester abortion two years previously. INTERVENTION: Vacuum aspiration or medical abortion using mifepristone and gemeprost. MAIN OUTCOME MEASURES: Long-term general, reproductive and psychological health; acceptability of procedure; perceived value of choice of method of termination. RESULTS: There were no significant differences between women who had undergone medical abortion or vacuum aspiration two years previously in general, reproductive or psychological health. Almost all women placed a high value on the provision of choice of method of termination. There was a significant difference in perception of long term procedure acceptability among women who had been randomised to a method of termination. CONCLUSIONS: Women should have the opportunity to choose the method of termination. This opportunity will result in high levels of acceptability, particularly at gestations under 50 days of amenorrhoea.

A comparison of medical abortion (using mifepristone and gemeprost) with surgical vacuum aspiration: efficacy and early medical sequelae.

A total of 363 women undergoing legal abortion at < 63 days of amenorrhoea were allocated by a patient-centered, partially randomized study design to undergo medical abortion (using mifepristone 600 mg followed 48 h later by gemeprost 1 mg vaginal pessary) or vacuum aspiration (performed under general anaesthesia). The aim of the study was to compare the efficacy and complications of the two procedures. Main outcome measures included efficacy rates, medical complications within 21 days of abortion and unplanned family doctor consultation rates within 8 weeks following abortion. Sequelae such as pain, vaginal bleeding and recovery time were assessed by the change in haemoglobin level, the time taken to return to work or normal activity and the analgesic use. Results were gestation-related; at 50 days of amenorrhoea there was little to choose between the two procedures. At 50-63 days of amenorrhoea medical abortion becomes more painful and less effective, whereas vacuum aspiration retains high tolerance and efficacy. Women who are unsure which method to use are likely to find vacuum aspiration more acceptable at longer gestations.

Comparison of medical abortion with surgical vacuum aspiration: women's preferences and acceptability of treatment.

OBJECTIVES: To assess women's preferences for, and the acceptability of, medical abortion and vacuum aspiration in the early first trimester. DESIGN: Patient centred, partially randomised trial. Medical abortion was performed with mifepristone 600 mg followed 48 hours later by gemeprost 1 mg vaginal pessary. Vacuum aspiration was performed under general anaesthesia. SETTING: Teaching hospital in Scotland. PATIENTS: 363 women undergoing legal induced abortion at less than nine weeks' gestation. MAIN OUTCOME MEASURES: Women's preferences for method of abortion before abortion; acceptability judged two weeks after abortion by recording the method women would opt to undergo in future and by semantic differential rating technique. RESULTS: 73 (20%) women preferred to undergo medical abortion, and 95 (26%) vacuum aspiration; 195 (54%) were willing to undergo either method, and were allocated at random. Both procedures were highly acceptable to women with preferences. Gestation had a definite effect on acceptability in randomised women; at less than 50 days there were no differences, but between 50 and 63 days vacuum aspiration was significantly more acceptable. CONCLUSIONS: Women who wish to use a particular method should be allowed their choice, regardless of gestation. Women of 50-63 days' gestation without preferences for a particular method are likely to find vacuum aspiration more acceptable. A patient centred, partially randomised trial design may be a useful tool in pragmatic research.

Improving the selection of patients for upper gastrointestinal endoscopy.

A retrospective study was undertaken to investigate how endoscopies yielding positive findings differ a priori from those yielding negative findings: and how those judged 'helpful' (in the sense of influencing management) differ a priori from those judged 'unhelpful'. A total of 483 patients undergoing endoscopy was sampled and a wide range of data abstracted, including 48 patient characteristics available to the gastroenterologist at the time of the decision to perform endoscopy. Sixty nine per cent of endoscopies were positive. Multivariate statistical analysis identified four variables which taken together were strongly predictive of a positive endoscopy. The resulting mathematical formula correctly predicted the outcome of 76% of endoscopies. Eighty two per cent of the endoscopies were retrospectively classified by the gastroenterologists as helpful. Six variables were strongly predictive of a helpful endoscopy. The corresponding formula correctly predicted the finding of 84% of endoscopies. Comparison of the two analyses shows that the two sets of predictions differ substantially. Thus it is important that decision tools should be based not on the crude distinction between positive and negative, but on the more useful distinction between helpful and unhelpful in influencing management.

Self- and other-awareness of the risk of HIV/AIDS in people with haemophilia and implications for behavioural change.

Many people with haemophilia have been infected by HIV through the contamination of blood products they need for treatment of their bleeding. This study explored the perceptions of people with haemophilia of their own and others' risk of HIV/AIDS and their beliefs about others' perceptions of HIV/AIDS. The results have shown that many patients are not willing to disclose the existence of their haemophilia to certain categories of people and have a firm view of who should and should not know about their HIV antibody status. The patients' beliefs of others' perceptions of HIV and AIDS are associated with (a) their perceptions of risk for themselves and others and (b) with behavioural change to prevent the spread of HIV.

Daily living problems of people with haemophilia and HIV infection: implications for counselling.

The advent of AIDS not only signifies the emergence of a new disease that affects hitherto healthy members of the general population but also highlights many unresolved problems of people with haemophilia, a life-long genetic disorder of blood clotting. Although HIV infection and the threat of AIDS has been a tragedy for people with haemophilia, the reported study shows that in spite of recent technological advancement in treatment, problems caused by haemophilia as such are still devastating for some severely affected patients. The ability of people with haemophilia to cope with their daily living problems such as chronic and acute pain, stress in the family, difficulties with unemployment and social relationships affects their response to HIV/AIDS. These facts have important implications for their rehabilitation and counselling and raise questions about coping with HIV/AIDS for other risk groups.

HIV infection and Scottish general practice: workload and current practice.

To estimate the effect of human immunodeficiency virus (HIV) infection on general practice, a postal survey was undertaken of one in three of all principals in Scotland. Of the 834 general practitioners who responded (78% response rate), 31% were working in practices with patients known to be infected with HIV. The estimated prevalence of known HIV infection in general practice was 19 per 100,000 population, and the estimated annual consultation rate for HIV related problems (including consultations by the 'worried well') was seven per 1000 population. Both statistics showed considerable variation between health boards, with peaks in Lothian and Tayside. Few practices had drawn up policies relevant to HIV infection, and the use of procedures for controlling infection was variable. Policies about HIV and for infection control tended to be more common in areas where the prevalence of HIV infection was higher. Most respondents were offering both opportunistic health education and counselling about HIV infection, especially to patients at high risk. Although general practitioners are responding positively to the increasing demands of HIV infection, there is an urgent need for policies, both national and local, to guide specific aspects of practice.

HIV infection and Scottish general practice: knowledge and attitudes.

To assess the knowledge and attitudes of general practitioners about HIV infection, a postal survey was undertaken of one in three of all principals in Scotland; 834 (77.6%) responded. Respondents' knowledge about HIV was often limited, and they found the discussion of sexual behaviour difficult. Most were in favour of routine HIV testing being offered to patients, but against testing without consent. Most general practitioners considered consent unnecessary for the passing of information about HIV status between medical colleagues, but necessary for informing others, in particular the patient's family and sexual partners. Most general practitioners would accept high-risk and HIV-positive patients onto their lists but less than half would accept intravenous drug users. Most respondents did not feel at significant personal risk of HIV infection, but expressed reservations about many other aspects of HIV infection in general practice. If practitioners are to fulfil their potential for tackling the problems of HIV infection, they need increased resources and a policy for education and training that is responsive to local needs.

Training clinical teachers in psychiatry to teach interviewing skills to medical students.

To study the feasibility of training all clinical teachers in psychiatry to teach interviewing skills to medical students, 24 (unselected clinicians were assigned to one of four different training methods. They received either experiential or didactic instruction, and their initial teaching sessions were either supervised or unsupervised. A total of 287 medical students subsequently received feedback training from these teachers. While all students showed significant increases in skill after training, those taught by experientially trained teachers showed the greatest gains. Neither supervision nor the teachers' own interviewing skills exerted significant effects on students' performance. It is concluded that with only brief training unselected clinicians can become effective teachers of essential interviewing skills. Feedback training in such skills can, therefore, be incorporated into existing curricula without major disruption of other requirements.
