ItemQuit in General Practice: a cluster randomised trial of enhanced in-practice support for smoking cessation(BMC, 2010-08-12)BACKGROUND: This study will test the uptake and effectiveness of a flexible package of smoking cessation support provided primarily by the practice nurse (PN) and tailored to meet the needs of a diversity of patients. METHODS/DESIGN: This study is a cluster randomised trial, with practices allocated to one of three groups 1) Quit with Practice Nurse 2) Quitline referral 3) GP usual care. PNs from practices randomised to the intervention group will receive a training course in smoking cessation followed by access to mentoring. GPs from practices randomised to the Quitline referral group will receive information about the study and the process of written referral and GPs in the usual care group will receive information about the study. Eligible patients are those aged 18 and over presenting to their GP who are daily or weekly smokers and who are able to give informed consent. Patients on low incomes in all three groups will be able to access free nicotine patches.Primary outcomes are sustained abstinence and point prevalence abstinence at the three month and 12 month follow-up points; and incremental cost effectiveness ratios at 12 months. Process evaluation on the reach and acceptability of the intervention approached will be collected through Computer Assisted Telephone Interviews (CATI) with patients and semi-structured interviews with PNs and GPs.The primary analysis will be by intention to treat. Cessation outcomes will be compared between the three arms at three months and 12 month follow-up using multiple logistic regression. The incremental cost effectiveness ratios will be estimated for the 12 month quit rate for the intervention groups compared to usual care and to each other. Analysis of qualitative data on process outcomes will be based on thematic analysis. DISCUSSION: High quality evidence on effectiveness of practice nurse interventions is needed to inform health policy on development of practice nurse roles. If effective, flexible support from the PN in partnership with the GP and the Quitline could become the preferred model for providing smoking cessation advice in Australian general practice. TRIAL REGISTRATION: ACTRN12609001040257.

ItemParticipant demographics reported in "Table 1" of randomised controlled trials: a case of "inverse evidence"?(BMC, 2012-03-19)INTRODUCTION: Data supporting external validity of trial results allows clinicians to assess the applicability of a study's findings to their practice population. Socio-economic status (SES) of trial participants may be critical to external validity given the relationship between social and economic circumstances and health. We explored how this is documented in reports of RCTs in four major general medical journals. METHODS: The contents lists of four leading general medical journals were hand searched to identify 25 consecutive papers reporting RCT results in each journal (n = 100). Data on demographic characteristics were extracted from each paper's Table 1 only (or equivalent). RESULTS: Authors infrequently reported key demographic characteristics relating to SES of RCT participants. Age and gender of participants were commonly reported. Less than 10% reported occupational group, employment status, income or area based measures of disadvantage. CONCLUSIONS: Without adequate reporting of key indicators of SES in trial participants it is unclear if lower SES groups are under-represented. If such groups are systematically under-recruited into trials, this may limit the external validity and applicability of study findings to these groups. This is in spite of the higher health-care need in more disadvantaged populations. Under-representation of low SES groups could underestimate the reported effect of an intervention for those with a higher baseline risk. The marginal benefit identified in a trial with poor or no representation of lower SES participants could significantly underestimate the potential benefit to a low SES community. More transparency in this reporting and greater attention to the impact of SES on intervention outcomes in clinical trials is needed. This could be considered in the next revision of the CONSORT statement.

ItemThe ethics of everyday practice in primary medical care: responding to social health inequities.(Springer Science and Business Media LLC, 2010-05-03)BACKGROUND: Social and structural inequities shape health and illness; they are an everyday presence within the doctor-patient encounter yet, there is limited ethical guidance on what individual physicians should do. This paper draws on a study that explored how doctors and their professional associations ought to respond to the issue of social health inequities. RESULTS: Some see doctors as bound by a notion of care that is blind to a patient's social position, while others respond to this issue through invoking notions of justice and human rights where access to care is a prime focus. Both care and justice orientations however conceal important tensions linked to the presence of bioethical principles underpinning these. Other normative ethical theories like deontology, virtue ethics and utilitarianism do not provide adequate guidance on the problem of social health inequities either. CONCLUSION: This paper explores if Bauman's notion of "forms of togetherness" provides the basis of a relational ethical theory that can help to develop a response to social health inequities of relevance to individual physicians. This theory goes beyond silence on the influence of social position of health and avoids amoral regulatory approaches to monitoring equity of care provision.

ItemThe "cost" of treating to target: cross-sectional analysis of patients with poorly controlled type 2 diabetes in Australian general practice(BMC, 2013-03-08)BACKGROUND: To describe the current treatment gap in management of cardiovascular risk factors in patients with poorly controlled type 2 diabetes in general practice as well as the associated financial and therapeutic burden of pharmacological treatment. METHODS: Cross-sectional analysis of data from the Patient Engagement and Coaching for Health trial. This totalled 473 patients from 59 general practices with participants eligible if they had HbA1c > 7.5%. Main outcome measures included proportions of patients not within target risk factor levels and weighted average mean annual cost for cardiometabolic medications and factors associated with costs. Medication costs were derived from the Australian Pharmaceutical Benefits Schedule. RESULTS: Average age was 63 (range 27-89). Average HbA1c was 8.1% and average duration of diabetes was 10 years. 35% of patients had at least one micro or macrovascular complication and patients were taking a mean of 4 cardio-metabolic medications. The majority of participants on treatment for cardiovascular risk factors were not achieving clinical targets, with 74% and 75% of patients out of target range for blood pressure and lipids respectively. A significant proportion of those not meeting clinical targets were not on treatment at all. The weighted mean annual cost for cardiometabolic medications was AUD$1384.20 per patient (2006-07). Independent factors associated with cost included age, duration of diabetes, history of acute myocardial infarction, proteinuria, increased waist circumference and depression. CONCLUSIONS: Treatment rates for cardiovascular risk factors in patients with type 2 diabetes in our participants are higher than those identified in earlier studies. However, rates of achieving target levels remain low despite the large 'pill burden' and substantial associated fiscal costs to individuals and the community. The complexities of balancing the overall benefits of treatment intensification against potential disadvantages for patients and health care systems in primary care warrants further investigation.

ItemA systematic review of interventions to enhance access to best practice primary health care for chronic disease management, prevention and episodic care(BMC, 2012-11-21)BACKGROUND: Although primary health care (PHC) is a key component of all health care systems, services are not always readily available, accessible or affordable. This systematic review examines effective strategies to enhance access to best practice processes of PHC in three domains: chronic disease management, prevention and episodic care. METHODS: An extensive search of bibliographic data bases to identify peer and non-peer reviewed literature was undertaken. Identified papers were screened to identify and classify intervention studies that measured the impact of strategies (singly or in combination) on change in use or the reach of services in defined population groups (evaluated interventions). RESULTS: The search identified 3,148 citations of which 121 were intervention studies and 75 were evaluated interventions. Evaluated interventions were found in all three domains: prevention (n = 45), episodic care (n = 19), and chronic disease management (n = 11). They were undertaken in a number of countries including Australia (n = 25), USA (n = 25), and UK (n = 15). Study quality was ranked as high (31% of studies), medium (61%) and low (8%). The 75 evaluated interventions tested a range of strategies either singly (n = 46 studies) or as a combination of two (n = 20) or more strategies (n = 9). Strategies targeted both health providers and patients and were categorised to five groups: practice re-organisation (n = 43 studies), patient support (n = 29), provision of new services (n = 19), workforce development (n = 11), and financial incentives (n = 9). Strategies varied by domain, reflecting the complexity of care needs and processes. Of the 75 evaluated interventions, 55 reported positive findings with interventions using a combination of strategies more likely to report positive results. CONCLUSIONS: This review suggests that multiple, linked strategies targeting different levels of the health care system are most likely to improve access to best practice PHC. The proposed changes in the structure of PHC in Australia may provide opportunities to investigate the factors that influence access to best practice PHC and to develop and implement effective, evidence based strategies to address these.

ItemFACTORS INFLUENCING ACCESS TO URBAN GENERAL PRACTICES AND PRIMARY HEALTH CARE BY ABORIGINAL AUSTRALIANS-A QUALITATIVE STUDY(SAGE PUBLICATIONS LTD, 2012-03)This paper aims to explore the barriers and facilitators for Aboriginal and Torres Strait Islander Australians with chronic disease to access urban, mainstream general practice and primary health care. Six focus groups and five interviews were conducted with 40 participants that included Aboriginal people with diabetes, health service providers and policy makers. Using diabetes as the exemplar, participants were asked to relate their own experiences of diabetes management. Data was thematically analysed. Two overarching themes and seven other factors were identified as influencing Aboriginal people's access to health services. Cultural competence can be achieved within a health service when all nine factors are addressed in the context of the local community. Closing the health gap between Aboriginal and non-Aboriginal Australians requires a particular sensitivity and understanding of the facilitators and barriers for urban Aboriginal people accessing mainstream health services.

ItemNo Preview AvailableEffectiveness of general practice based, practice nurse led telephone coaching on glycaemic control of type 2 diabetes: the Patient Engagement And Coaching for Health (PEACH) pragmatic cluster randomised controlled trial(BMJ PUBLISHING GROUP, 2013-09-18)OBJECTIVE: To evaluate the effectiveness of goal focused telephone coaching by practice nurses in improving glycaemic control in patients with type 2 diabetes in Australia. DESIGN: Prospective, cluster randomised controlled trial, with general practices as the unit of randomisation. SETTING: General practices in Victoria, Australia. PARTICIPANTS: 59 of 69 general practices that agreed to participate recruited sufficient patients and were randomised. Of 829 patients with type 2 diabetes (glycated haemoglobin (HbA1c) >7.5% in the past 12 months) who were assessed for eligibility, 473 (236 from 30 intervention practices and 237 from 29 control practices) agreed to participate. INTERVENTION: Practice nurses from intervention practices received two days of training in a telephone coaching programme, which aimed to deliver eight telephone and one face to face coaching episodes per patient. MAIN OUTCOME MEASURES: The primary end point was mean absolute change in HbA1c between baseline and 18 months in the intervention group compared with the control group. RESULTS: The intervention and control patients were similar at baseline. None of the practices dropped out over the study period; however, patient attrition rates were 5% in each group (11/236 and 11/237 in the intervention and control group, respectively). The median number of coaching sessions received by the 236 intervention patients was 3 (interquartile range 1-5), of which 25% (58/236) did not receive any coaching sessions. At 18 months' follow-up the effect on glycaemic control did not differ significantly (mean difference 0.02, 95% confidence interval -0.20 to 0.24, P=0.84) between the intervention and control groups, adjusted for HbA1c measured at baseline and the clustering. Other biochemical and clinical outcomes were similar in both groups. CONCLUSIONS: A practice nurse led telephone coaching intervention implemented in the real world primary care setting produced comparable outcomes to usual primary care in Australia. The addition of a goal focused coaching role onto the ongoing generalist role of a practice nurse without prescribing rights was found to be ineffective. TRIAL REGISTRATION: Current Controlled Trials ISRCTN50662837.

ItemNegotiations of distress between East Timorese and Vietnamese refugees and their family doctors in Melbourne(WILEY-BLACKWELL, 2010-05)Recent critiques of depression have contested its coherence as a concept and highlighted its performance in medicalising distress. Studies of depression in a cross-cultural context have focused on language and belief systems as technical barriers to practice that need to be overcome in enacting depression work. This paper seeks to locate culture within the broader socio-structural context of depression care in general practice. The paper draws on interviews with five general practitioners (GPs), and 24 patients from Vietnamese and East Timorese backgrounds who predominantly have left their home as refugees. Each had been diagnosed with depression or prescribed antidepressants. These patients gave accounts of distress deeply embedded within, and inseparable from, lives fraught with frightening pre-migration experiences, traumatic escape and profound dislocation and alienation in their new 'home'. Fragmented lives were contrasted with the nourishing social fabric of homes left behind. GP participants were involved in a process of engaging with a profoundly communal and structural account of emotional distress while defending and drawing on an individualised notion of depression in performing their work and accounting for the pain presented to them.
