A randomised controlled trial of a consumer-focused e-health strategy for cardiovascular risk management in primary care: the Consumer Navigation of Electronic Cardiovascular Tools (CONNECT) study protocol.

INTRODUCTION: Fewer than half of all people at highest risk of a cardiovascular event are receiving and adhering to best practice recommendations to lower their risk. In this project, we examine the role of an e-health-assisted consumer-focused strategy as a means of overcoming these gaps between evidence and practice. Consumer Navigation of Electronic Cardiovascular Tools (CONNECT) aims to test whether a consumer-focused e-health strategy provided to Aboriginal and Torres Strait Islander and non-indigenous adults, recruited through primary care, at moderate-to-high risk of a cardiovascular disease event will improve risk factor control when compared with usual care. METHODS AND ANALYSIS: Randomised controlled trial of 2000 participants with an average of 18 months of follow-up to evaluate the effectiveness of an integrated consumer-directed e-health portal on cardiovascular risk compared with usual care in patients with cardiovascular disease or who are at moderate-to-high cardiovascular disease risk. The trial will be augmented by formal economic and process evaluations to assess acceptability, equity and cost-effectiveness of the intervention. The intervention group will participate in a consumer-directed e-health strategy for cardiovascular risk management. The programme is electronically integrated with the primary care provider's software and will include interactive smart phone and Internet platforms. The primary outcome is a composite endpoint of the proportion of people meeting the Australian guideline-recommended blood pressure (BP) and cholesterol targets. Secondary outcomes include change in mean BP and fasting cholesterol levels, proportion meeting BP and cholesterol targets separately, self-efficacy, health literacy, self-reported point prevalence abstinence in smoking, body mass index and waist circumference, self-reported physical activity and self-reported medication adherence. ETHICS AND DISSEMINATION: Primary ethics approval was received from the University of Sydney Human Research Ethics Committee and the Aboriginal Health and Medical Research Council. Results will be disseminated via the usual scientific forums including peer-reviewed publications and presentations at international conferences CLINICAL TRIALS REGISTRATION NUMBER: ACTRN12613000715774.

Identifying patient-specific beliefs and behaviours for conversations about adherence in asthma.

BACKGROUND: Asthma guidelines advise addressing adherence at every visit, but no simple tools exist to assist clinicians in identifying key adherence-related beliefs or behaviours for individual patients. AIMS: To identify potentially modifiable beliefs and behaviours that predict electronically recorded adherence with controller therapy. METHODS: Patients aged ≥ 14 years with doctor-diagnosed asthma who were prescribed inhaled corticosteroid/long-acting ß(2)-agonist (ICS/LABA) completed questionnaires on medication beliefs/behaviours, side-effects, Morisky adherence behaviour score and Asthma Control Test (ACT), and recorded spirometry. Adherence with ICS/LABA was measured electronically over 8 weeks. Predictors of adherence were identified by univariate and multivariate analyses. RESULTS: 99/100 patients completed the study (57 female; forced expiratory volume in 1 s mean ± standard deviation 83 ± 23% predicted; ACT 19.9 ± 3.8). Mean electronically recorded adherence (n= 85) was 75% ± 25, and mean self-reported adherence was 85% ± 26%. Factor analysis of questionnaire items significantly associated with poor adherence identified seven themes: perceived necessity, safety concerns, acceptance of asthma chronicity/medication effectiveness, advice from friends/family, motivation/routine, ease of use and satisfaction with asthma management. Morisky score was moderately associated with actual adherence (r=-0.45, P < 0.0001). In regression analysis, 10 items independently predicted adherence (adjusted R(2) = 0.67; P < 0.001). Opinions of friends/family about the patient's medication use were strongly associated with poor adherence. Global concerns about ICS/LABA therapy were more predictive of poor adherence than were specific side-effects; the one-third of patients who reported experiencing side-effects from their steroid inhaler had lower adherence than others (mean 62% vs 81%; P= 0.015). CONCLUSIONS: This study identified several specific beliefs and behaviours which clinicians could use for initiating patient-centred conversations about medication adherence in asthma.

A pragmatic cluster randomized controlled trial of an educational intervention for GPs in the assessment and management of depression.

BACKGROUND: General practitioners (GPs) can be provided with effective training in the skills to manage depression. However, it remains uncertain whether such training achieves health gain for their patients. METHOD: The study aimed to measure the health gain from training GPs in skills for the assessment and management of depression. The study design was a cluster randomized controlled trial. GP participants were assessed for recognition of psychological disorders, attitudes to depression, prescribing patterns and experience of psychiatry and communication skills training. They were then randomized to receive training at baseline or the end of the study. Patients selected by GPs were assessed at baseline, 3 and 12 months. The primary outcome was depression status, measured by HAM-D. Secondary outcomes were psychiatric symptoms (GHQ-12) quality of life (SF-36), satisfaction with consultations, and health service use and costs. RESULTS: Thirty-eight GPs were recruited and 36 (95%) completed the study. They selected 318 patients, of whom 189 (59%) were successfully recruited. At 3 months there were no significant differences between intervention and control patients on HAM-D, GHQ-12 or SF-36. At 12 months there was a positive training effect in two domains of the SF-36, but no differences in HAM-D, GHQ-12 or health care costs. Patients reported trained GPs as somewhat better at listening and understanding but not in the other aspects of satisfaction. CONCLUSIONS: Although training programmes may improve GPs' skills in managing depression, this does not appear to translate into health gain for depressed patients or the health service.

Health and access issues among Australian adolescents: a rural-urban comparison.

INTRODUCTION: Previous research has reported rural-urban differences in health concerns and access issues. However, very little of this has concerned young people, and what has been published has been mainly from countries other than Australia and may not generalise to Australian youth. The study described in this paper is a subset of a larger study on health concerns and access to healthcare for younger people (12-17 years) living in New South Wales (NSW), Australia. This paper reports findings on rural-urban similarities and differences. The specific study objective was to identify and describe rural-urban differences, especially those associated with structural disadvantage. METHOD: The reported findings form part of a larger state-wide cross-sectional study of access to healthcare among NSW adolescents. Adolescents were drawn from high schools in ten of the 17 Area Health Services in NSW. These Area Health Services were selected because they represent most aspects of rural-urban NSW with respect to population characteristics and health services. Eighty-one focus groups were conducted with adolescents (35 with boys and 46 with girls), of which 56 were conducted in urban, 22 in rural and 3 in regional areas. The focus groups were tape-recorded, transcribed and analysed using the computer software package NUD*IST 4. RESULTS: The analysis revealed certain health concerns that were common to both rural and urban adolescents: use of alcohol and illicit drugs, bullying, street safety, diet and body image, sexual health, stress and depression. However, certain concerns were mentioned more frequently in rural areas (eg depression), and two concerns were raised almost exclusively by rural youth (youth suicide and teenage pregnancy). There were also structural differences in service provision: adolescents in rural areas reported disadvantage in obtaining access to healthcare (limited number of providers and lengthy waiting times); having only a limited choice of providers (eg only one female doctor available), and cost (virtually no bulk billing--ie direct charge to Medicare with no patient co-payment). A lack of confidentiality as a barrier to seeking service access was raised by both rural and urban youth, but was a major concern in rural areas. No issues specific to urban areas were raised by urban youth. Male and female rural adolescents were more likely than urban adolescents to express concerns over limited educational, employment and recreational opportunities, which they believed contributed to their risk-taking behaviour. Gender differences were evident for mental health issues, with boys less able to talk with their peers or service providers about stress and depression than girls. These gender differences were evident among adolescents in both rural and urban areas, but the ethos of a self-reliant male who does not ask for help was more evident among rural boys. CONCLUSIONS: While Australian rural and urban youth shared many health concerns, rural-urban differences were striking in the almost exclusive reporting of youth suicide and teenage pregnancy by rural adolescents. The findings suggest that structural disadvantage in rural areas (limited educational, employment opportunities, and recreational facilities) impact adversely on health outcomes, particularly mental health outcomes, and contribute to risk-taking behaviour. Such disadvantages should be considered by health-service policy makers and providers to redress the imbalance. Gender differences were also evident and efforts to target the specific needs of Australian adolescent boys are warranted.

Do general practitioners' attitudes towards depression predict their clinical behaviour?

BACKGROUND: GPs' attitudes towards depression vary, as do their abilities to detect and manage it effectively. Associations between attitudes and clinical behaviour have not yet been demonstrated directly. We tested two hypotheses: (1) that questionnaire measures of GPs' confidence in identifying depression predict their ability to identify depression in their patients; and (2) that GPs who prefer antidepressants prescribe more than those who prefer psychotherapy. METHODS: Forty GPs in Liverpool and Manchester completed the Depression Attitude Questionnaire (DAQ) and were asked for prescribing (PACT) information. Attender surveys using the General Health Questionnaire (GHQ-12), in combination with GP ratings of patients' psychological status, generated indices for GPs' case identification, bias and accuracy. We tested associations between these indices and the four DAQ components, in particular GPs' confidence in diagnosis, across a total of 1436 patients. We also compared the DAQ component on attitudes to treatment with relevant PACT data. RESULTS: The DAQ assessment of GPs' ability to identify cases of depression bore no relationship to their observed ability, as measured by accuracy, bias, or identification indices. However, there were significant associations between observed diagnostic ability and: preference for psychotherapy; ease in managing depression; and, belief in successful treatment. PACT data were available for 26 (65%) GPs. There was an association between preference for antidepressants and prescription of SSRIs (rs 0.3981, P < 0.044), but not for overall antidepressant or tricyclic prescribing, or for dose of dothiepin. CONCLUSIONS: The DAQ measure of ease of identification is not valid when compared to actual clinical practice. The ability of GPs to identify depression may not be an independent variable, but may rather reflect other beliefs, attitudes and skills. This has considerable implications for educational interventions in primary care.

Improving cervical screening in a remote aboriginal community.

Improved cervical screening has been identified as a priority in reducing the incidence of cervical cancer among Aboriginal women. This paper discusses the cervical screening recommendations of a women's health project developed by Nganampa Health Council (NHC), the Aboriginal-controlled medical service meeting the health needs of the people of the Anangu Pitjantjatjara (AP) Lands. A community participation public health model was used in program development. A process including community and staff consultation, literature review and prioritisation informed the program development, ensuring strategies thereby derived were culturally acceptable as well as practical and scientifically valid. The epidemiology of cervical cancer and screening in this community is discussed. Strategies aimed at maximising patient participation, improving patient satisfaction, running an effective call and recall system, improving quality of cervical smears, improving management of women with abnormal smears and evaluating the program are suggested. The involvement of the community in a scientifically sound, public health approach may increase the likelihood that the strategies suggested will be effective in this community. Both the model of program development and the cervical screening strategies derived are likely to be of relevance for other Aboriginal communities.

Deriving a preference-based single index from the UK SF-36 Health Survey.

This article presents the results of a study to derive a preference-based single index from the SF-36. The study was an attempt to reconcile a profile health status measure, the SF-36, with the "quality adjusted life years" approach. The study undertook a parsimonious restructuring of the SF-36 using explicit criteria to form the SF-6D health state classification. A sample of multidimensional health states defined by this classification were valued by a convenience sample of health professionals, managers, and patients, who responded to a set of visual analogue scale ratings and standard gamble questions, with highly complete and consistent answers. Statistical models were estimated to predict single index scores for all 9000 health states defined by the new classification. The resultant algorithms can be applied to existing SF-36 data sets and used in the assessment of the cost-effectiveness of health technologies. This preliminary work forms the basis of a larger study currently being undertaken in the UK.

Evaluation of a training package in the assessment and management of depression in primary care.

This study aimed to evaluate the impact on the behaviour and attitudes of experienced general practitioners of a 10-hour training package in the assessment and management of depression. Twenty general practitioners participated. Both subjective and objective assessments were carried out which suggested significant improvements in both assessment and management skills. However, subjectively reported changes were not always supported by the objective data obtained from rating role-played interviews. The role-played patients rated the doctors as better communicators after training. All participants felt attending the course was beneficial. They all felt more confident in their abilities to deal with depression and said the skills they had learnt on the course would be useful to them in their future work. An outcome study is now underway in order to assess whether the training package, which has been demonstrated to have an impact on the behaviour, skills and attitudes of doctors, has an impact on the health of patients.

The effects on prescribing patterns and costs of having a special interest in asthma.

To define the characteristics of general practices with a special clinical interest in asthma and to estimate the resulting extra prescribing costs, we sent a postal questionnaire to all English practices containing members of the General Practitioners in Asthma Group. Item and cost comparisons for 24 PACT (prescribing analysis and cost) aggregates were made between practices who had operated an agreed, written management plan for asthma before 1 April 1990 and all other practices in their respective Family Health Services Authorities. One hundred and sixty-three practices with GPIAG members responded (70%), of which 26 filled the management plan requirement. These 26 practices showed evidence of significantly better asthma care provision than the remainder of the sample. Their prescribing costs were significantly higher for respiratory drugs (median 37% higher) but lower in other drug categories. For respiratory drugs, costs were significantly higher for inhaled adrenoceptor stimulants, steroid inhalers, large spacers, and peak flow meters, but lower for cough medicines and systemic nasal decongestants: the number of items prescribed showed similar patterns. The prescribing costs of practices claiming a special interest in asthma are likely to show higher respiratory drug costs, but overall prescribing costs showed no increase in the practices studied.

General practitioner's knowledge of when to refer deaths to a coroner.

BACKGROUND: In 1992 about 179,000 deaths were reported to coroners in England and Wales and these represented 32% of the total number of registered deaths. Many of these cases were referred to coroners by general practitioners who certify the vast majority of deaths which occur outside hospitals. The safeguards to society which are provided by the coroner system in England and Wales are undermined if doctors fail to recognize those deaths which should be reported for further investigation. AIM: A study was undertaken to assess the ability of general practitioners to recognize deaths which require referral to a coroner. METHOD-A postal questionnaire consisting of 12 fictitious case histories was sent to all 323 general practitioners in Sheffield and the senior staff of the local coroner's office (two coroner's officers and two deputy coroners). Ten of the case histories contained a clear indication for referral to the coroner. RESULTS: A total fo 196 general practitioners (61%) and all the coroner's office staff returned the questionnaire. General practitioners correctly identified whether or not referral was indicated, with reasons, in a mean of 8.5 cases (range 4-12). Only six general practitioners (3%) were correct in all 12 cases. All of the coroner's staff were correct in all cases. CONCLUSION: General practitioners may be failing to bring certain categories of cases to the attention of coroners because of misconceptions of ignorance of their medico-legal responsibilities. General practitioner education in this area, and a closer working relationship between general practitioners and coroners may improve the situation.

Competence-based summative assessment of a student-directed course: involvement of key stakeholders.

The 5-week module in general practice for final-year students at the University of Sheffield is based on practice attachments and student-directed learning in small groups. This paper describes how the summative assessment process of the module was revised to incorporate the notion of competence-based assessment, and how general practitioner tutors, departmental tutors and students were involved in this revision. The question 'What are students expected to know and be able to do by the end of the module?' was answered in terms of a statement of the key purpose of the module and a list of intended learning outcomes. The question 'How can we find out if students have achieved these outcomes?' was addressed by developing check-lists of criteria for observed behaviours and for the written products of students' actions.

Self-perceived health status of hostel residents: use of the SF-36D health survey questionnaire. Hanover Project Team.

As part of a project to assess the health needs of homeless people in Sheffield, a survey of hostel residents was undertaken with the aim of measuring self-perceived health and health service use among respondents. The survey instrument incorporated the SF-36D short-form health survey questionnaire. One hundred and four (56 per cent) adult hostel residents responded. Respondents reported high levels of health service use, and poor average perceived health in comparison with the general population. Three-quarters of respondents were identified as being at risk of major depressive illness. There was a strong association between risk of major depression and recent hospital contact, current use of prescribed medication, and low scores on the social function, mental health, energy/vitality, pain and general health dimensions of the SF-36. The implications of these findings are discussed.

The provision and use of medical services during the 1991 World Student Games in Sheffield.

This paper describes the provision and use of medical services organized by Sheffield during the World Student Games in 1991. A descriptive study of medical and physio-therapy records, together with minor incident logs and hospital referrals, was carried out. It was found that 571 medical records and 357 physiotherapy records were completed, of which 83 per cent were generated at the Games Village. The majority of patients were competitors, although team officials accounted for a disproportionate number. Most physiotherapy requests were for sports injuries, whereas this was not so for medical cases. Twenty-five per cent of medical records and 40 per cent of physiotherapy records were for recurrent conditions which had started before arrival. Athletics and football accounted for the greatest number of records per competitor. During the Games, 82 patients were referred to hospital, of whom only 12 were admitted. The largest group of hospital referrals was for dental treatment, and the next largest was for minor trauma. A total of 1089 minor incidents were recorded, mainly at the competition venues and in the Physiotherapy Room at the Games Village. In addition, the Red Cross and the St John Ambulance Association attended to 330 people during the Games. The smallest national teams tended to make most demands on services, probably because the larger teams were accompanied by their own medical and physiotherapy staff. It is concluded that the main demands for medical services at the World Student Games were for general practice and physiotherapy at the Games Village, and for first aid at competition venues.(ABSTRACT TRUNCATED AT 250 WORDS)

Subjective and behavioural evaluation of the teaching of patient interview skills.

One aim of the course in general practice and public health medicine during the final year at the University of Sheffield is to help students to develop further their interpersonal communication skills with particular reference to their skills in interviewing patients. During the course students meet twice in small groups with a tutor in order to review audiotape recordings of interviews with patients seen during their general practice attachments. The main activity during these tutorials is group discussion of the interviewer's behavioural options at significant points during the interview. Students also listen individually with a tutor to an interview that they have recorded, discuss this interview and assess it against a set of explicit criteria as part of their summative course assessment. In response to an anonymous end-of-course questionnaire, 85% of students felt that their interview skills had been improved by the teaching and 68% that listening to their own recordings had been the most helpful aspect. During interviews with simulated patients recorded at the end of the course, students asked more open questions, fewer questions referring to physical symptoms, more questions referring to feelings, beliefs or behaviour and fewer questions of a check-list type than during interviews recorded at the start. A number of students also requested examples of specific events during the end-of-course interviews although none had done so at the beginning of the course. All of these changes were statistically significant and were in directions that were consistent with the teaching in the small-group tutorials.

Practice organization before and after the new contract: a survey of general practices in Sheffield.

In order to assess the effects of the new contract on practice organization, all general practices in Sheffield were surveyed just before the new contract came into effect in April 1990, and again one year later. Of the 120 practices, 57% responded in 1990 and 61% in 1991, with 47% responding in both years. There were significant increases in the mean number of clinics and employed staff for the practices responding to both questionnaires and in the proportion of these practices which had a computer. These changes represent a response to the incentives and stated aims of the new contract.

Validating the SF-36 health survey questionnaire: new outcome measure for primary care.

OBJECTIVES: To test the acceptability, validity, and reliability of the short form 36 health survey questionnaire (SF-36) and to compare it with the Nottingham health profile. DESIGN: Postal survey using a questionnaire booklet together with a letter from the general practitioner. Non-respondents received two reminders at two week intervals. The SF-36 questionnaire was retested on a subsample of respondents two weeks after the first mailing. SETTING: Two general practices in Sheffield. PATIENTS: 1980 patients aged 16-74 years randomly selected from the two practice lists. MAIN OUTCOME MEASURES: Scores for each health dimension on the SF-36 questionnaire and the Nottingham health profile. Response to questions on recent use of health services and sociodemographic characteristics. RESULTS: The response rate for the SF-36 questionnaire was high (83%) and the rate of completion for each dimension was over 95%. Considerable evidence was found for the reliability of the SF-36 (Cronbach's alpha greater than 0.85, reliability coefficient greater than 0.75 for all dimensions except social functioning) and for construct validity in terms of distinguishing between groups with expected health differences. The SF-36 was able to detect low levels of ill health in patients who had scored 0 (good health) on the Nottingham health profile. CONCLUSIONS: The SF-36 is a promising new instrument for measuring health perception in a general population. It is easy to use, acceptable to patients, and fulfils stringent criteria of reliability and validity. Its use in other contexts and with different disease groups requires further research.
