[Show abstract][Hide abstract] ABSTRACT: The gold standard for the diagnosis of chronic obstructive pulmonary disease (COPD) is spirometry, but there are barriers to its use in primary care.
To externally validate the COPD Diagnostic Questionnaire (CDQ) as a diagnostic tool in patients at increased risk in Australian general practice and to compare its performance with other CDQ validation studies.
Patients were recruited from 36 general practices in Sydney, Australia. Former or current smokers aged 40-85 years with no prior COPD diagnosis were invited to a case-finding appointment with the practice nurse. The CDQ was collected and pre- and postbronchodilator spirometry was performed. Cases for whom complete CDQ data were present and the spirometry met quality standards were analysed.
Of 1,631 patients who attended case-finding recruitment, 1,054 (65%) could be analysed. Spirometry showed 13% had COPD. The ability of the CDQ to discriminate between patients with and without COPD was fair, represented by the area under the receiver operating characteristic curve of 0.713. With a CDQ cut-off point value of 16.5 the sensitivity was 80% and specificity 47% and, at a cut-off point value of 19.5, the sensitivity was 63% and specificity 70%.
The CDQ did not discriminate between patients with and without COPD accurately enough to use as a diagnostic tool in patients at increased risk of COPD in Australian general practice. Further research is needed on the value of the CDQ as a tool for selecting patients for spirometry.

[Show abstract][Hide abstract] ABSTRACT: Guidelines for management of hypertension and lipids recommend using cardiovascular absolute risk (CVAR) to manage patients. This randomized controlled trial investigated the impact of CVAR assessment in family practice on management of cardiovascular risk, including prescription of antihypertensive and lipid-lowering medication.
A cluster randomized controlled trial was conducted from 2008 to 2010 in Sydney, Australia. Family practices were randomized, and patients aged 45 to 69 years were invited to participate. Intervention family physicians (FP) were trained in use of CVAR, provided with an electronic CVAR calculator, and assessed their patients' absolute risk in a dedicated consultation. Control practice patients received a general health check. Primary outcome analyzed was the proportion of patients in each group on antihypertensive and/or lipid-lowering medication at 12 months. Multilevel logistic regression was performed to explore variables influencing changes in pharmacologic therapy.
The study recruited 36 FPs from 34 practices and 1,074 patients, of which 906 (84.4%) completed 12-month follow-up. At 12 months, there was no significant difference between the intervention and control groups in proportion of patients on antihypertensives (31.2% vs 34.3%, P = .31), but control group patients were more likely to be on lipid-lowering medications (30.2% vs 22.7%, P = .01). After multilevel analysis, this difference was not present. Intensification or reduction of pharmacologic therapy was associated with meeting treatment targets for blood pressure and lipids but not with the CVAR or intervention group.
Single-risk factor management remains a strong influence on FP prescribing practices. Shifting to an approach based on CVAR will require more intensive intervention.

[Show abstract][Hide abstract] ABSTRACT: Advance care planning provides patients with the ability to make their decisions known about how they would like to be treated if they lose capacity. Medical practitioners have a key role to play in providing information on advance care planning to their patients. This research explores their knowledge and attitudes to advance care planning and how this affects their practice.
To assess NSW medical practitioners' knowledge and self-reported practice of Advance Care Planning.
A survey of a random sample of 650 GPs, plus 350 medical specialists from specialties most often involved in end-of-life decisions. Respondents work-location post codes were subsequently used to assign respondents to one of NSW Area Health Services.
Medical practitioners' knowledge of and practice pertaining to ACP.
34% of specialists (n=110) and 24% of GPs (n=150) responded; the majority of respondents had heard of all ACP options. However, respondents' understanding of the uses and legal requirements of the relevant ACP options vary widely.
Respect for patient wishes expressed in advance directives is reassuringly high. The findings suggest significant misunderstanding by medical practitioners of terminologies and systems around substitute decision-making for incompetent persons. Further education and standardisation of terminologies and systems across different jurisdictions would assist in addressing these issues.. Low response rate, relating to only one legal jurisdiction, means results may not be generalisable.

[Show abstract][Hide abstract] ABSTRACT: Abstract Background: Advance care planning (ACP) is thought to enhance patient autonomy and improve end-of-life care. However, there is evidence that when patients engage in ACP, the resultant plans are often not implemented. This has been attributed to either nonadherence by health professionals or inadequacies in ACP such as inaccessibility of the plans, plans providing ambiguous or conflicting instructions, and inappropriate focus on the completion of documents rather than communication. However, it is not known whether these postulated reasons are consistent with the experiences and views of health care professionals providing end-of-life care in the community. Objective: Our aim was to explore the perspectives of general practitioners (GPs) on factors influencing the implementation of ACPs. Methods: We conducted semi-structured, open-ended interviews of a purposive sample of 17 Australian GPs. Interview transcripts were analysed using constructionist grounded theory utilizing NVivo 9 software. Results: Factors that were considered to have an important influence on the implementation of ACPs include: ACP factors such as form, legal standing, accessibility, clarity, currency, and specificity; illness factors such as quality of life, function, diagnosis, prognosis, and prognostic certainty; family factors such as family attitudes to ACP and different conceptualizations on whether care is provided to individuals or to a family unit; and organizational and care setting factors such as health care facility's attitudes and policies in relation to end-of-life care. Conclusions: Problems in implementation of ACPs are multifactorial and not necessarily due to deliberate nonadherence by health professionals. Potential solutions to improve the clinical impact of ACP are discussed.

[Show abstract][Hide abstract] ABSTRACT: A high proportion of smokers suffer from mental health problems including depression. Despite many of them wanting to stop smoking, low mood adversely affects their ability to quit.
To explore the experiences of smokers with self-reported depression, the relationship of smoking with mental health problems and the experiences of smokers while trying to quit. The study also explored what help within the primary care setting could assist in quitting.
Participants were recruited from a large general-practice-based smoking cessation trial. Participants who had indicated they were suffering from depression on a self-reported baseline survey were invited to participate. Semi-structured interviews were conducted over the telephone and digitally recorded. The interviews were transcribed and analysed using a phenomenological qualitative approach.
Sixteen interviews were conducted (11 females, 5 males). Mood disturbances were frequently reported as triggers for smoking and low mood was seen as a barrier to quitting. Perceived benefits of smoking when depressed were limited and for many, it was a learned response. A sense of hopelessness, lack of control over one's life and a lack of meaningful activities all emerged as important factors contributing to continued smoking. Participants felt that their quit attempts would be aided by better mood management, increased self-confidence and motivation and additional professional support.
Smoking and depression were found to be strongly interconnected. Depressed smokers interested in quitting may benefit from increased psychological help to enhance self-confidence, motivation and mood management, as well as a supportive general practice environment.
[Show abstract][Hide abstract] ABSTRACT: BACKGROUND: Interest in how to implement evidence-based practices into routine health care has never been greater. Primary care faces challenges in managing the increasing burden of chronic disease in an ageing population. Reliable prescriptions for translating knowledge into practice, however, remain elusive, despite intense research and publication activity. This study seeks to explore this dilemma in general practice by challenging the current way of thinking about healthcare improvement and asking what can be learned by looking at change through a complexity lens. METHODS: This paper reports the local level of an embedded case study of organisational change for better chronic illness care over more than a decade. We used interviews, document review and direct observation to explore how improved chronic illness care developed in one practice. This formed a critical case to compare, using pattern matching logic, to the common prescription for local implementation of best evidence and a rival explanation drawn from complexity sciences interpreted through modern sociology and psychology. RESULTS: The practice changed continuously over more than a decade to deliver better chronic illness care in line with research findings and policy initiatives -- re-designing care processes, developing community linkages, supporting patient self-management, using guidelines and clinical information systems, and integrating nurses into the practice team. None of these improvements was designed and implemented according to an explicit plan in response to a documented gap in chronic disease care. The process that led to high quality chronic illness care exhibited clear complexity elements of co-evolution, non-linearity, self-organisation, emergence and edge of chaos dynamics in a network of agents and relationships where a stable yet evolving way of organizing emerged from local level communicative interaction, power relating and values based choices. CONCLUSIONS: The current discourse of implementation science as planned system change did not match organisational reality in this critical case of improvement in general practice. Complexity concepts translated in human terms as complex responsive processes of relating fit the pattern of change more accurately. They do not provide just another fashionable blueprint for change but inform how researchers, policymakers and providers participate in improving healthcare.

[Show abstract][Hide abstract] ABSTRACT: To evaluate a partnership model of care for patients with a diagnosis of chronic obstructive pulmonary disease (COPD).Design, setting and participants: Cluster randomised controlled trial with blinded outcome assessment of 44 general practices in south-western Sydney comprising 451 people with a diagnosis of COPD, conducted between 2006 and 2009.
Participants from intervention group practices were visited at their home by a registered nurse with specific training in COPD care who worked with the general practitioner, the patient and other health professionals to develop and implement an individualised care plan based on best-practice guidelines. Participants from control group practices received usual care.
The primary outcome was disease-related quality of life measured using the St George's Respiratory Questionnaire (SGRQ) at 12-month follow-up. Other outcomes were overall quality of life, lung function, smoking status, immunisation status, patient knowledge of COPD, and health service use.
Of the 451 participants, 257 (57.8%) were confirmed as having COPD on post-bronchodilator spirometry. Follow-up was completed for 330 patients (73.2%). At 12 months, there was no statistically significant difference in the mean SGRQ scores between intervention and control groups (38.7 v 37.6; difference, 1.1; 95% CI, - 1.53-3.74; P = 0.41) or in measures of quality of life, lung function and smoking status. Compared with the control group, in the intervention group, attendance at pulmonary rehabilitation was more frequent (31.1% v 9.6%; OR, 5.16; 95% CI, 2.40-11.10; P = 0.002) and the mean COPD knowledge score was higher (10.5 v 9.8; difference, 0.70; CI, 0.10-1.21; P = 0.02).
The nurse-GP partnership intervention did not have an impact on disease-related quality of life at 12-month follow-up. However, there was evidence of improved quality of care, in particular, in attendance at pulmonary rehabilitation and patient knowledge of COPD.

[Show abstract][Hide abstract] ABSTRACT: BACKGROUND: Advance care planning (ACP) has been gaining prominence for its perceived benefits for patients in enhancing patient autonomy and ensuring high-quality end-of-life-care. Moreover, it has been postulated that ACP has positive effects on families and health professionals and their relationship with the patient. However, there is a paucity of studies examining the views of GPs on this issue. OBJECTIVE: To explore GP views on the impact that ACP has on interpersonal relationships among those involved in the patient's care. METHOD: Semi-structured, open-ended interviews of a purposive sample of 17 GPs. Interview transcripts were analysed using constructionist grounded theory methodology with QSR NVivo 9 software. RESULTS: ACP was seen as having both positive and negative impacts on interpersonal relationships. It was thought to enhance family relationships, help resolve conflicts between families and health professionals and improve trust and understanding between patients and health professionals. Negatively, it could take the family's attention away from patient care. The link between ACP and interpersonal relationships was perceived to be bidirectional-the nature of interpersonal relationship that patients have with their families and health professionals has a profound impact on what form of ACP is likely to be useful. CONCLUSION: Our study highlights the importance that GPs place on the link between ACP and the patient's interpersonal context. This has implications on how ACP is conducted in primary care settings that are considerably different from other care settings in their emphasis on continuity of care and long-term nature of relationships.
[Show abstract][Hide abstract] ABSTRACT: Chronic Obstructive Pulmonary Disease (COPD) is a leading cause of disability, hospitalization, and premature mortality. General practice is well placed to diagnose and manage COPD, but there is a significant gap between evidence and current practice, with a low level of awareness and implementation of clinical practice guidelines. Under-diagnosis of COPD is a world-wide problem, limiting the benefit that could potentially be achieved through early intervention strategies such as smoking cessation, dietary advice, and exercise. General practice is moving towards more structured chronic disease management, and the increasing involvement of practice nurses in delivering chronic care.
A pragmatic cluster randomised trial will test the hypothesis that intervention by a practice nurse-general practitioner (GP) team leads to improved health-related quality of life and greater adherence with clinical practice guidelines for patients with newly-diagnosed COPD, compared with usual care. Forty general practices in greater metropolitan Sydney Australia will be recruited to identify patients at risk of COPD and invite them to attend a case finding appointment. Practices will be randomised to deliver either practice nurse-GP partnership care, or usual care, to patients newly-diagnosed with COPD.The active intervention will involve the practice nurse and GP working in partnership with the patient in developing and implementing a care plan involving (as appropriate), smoking cessation, immunisation, pulmonary rehabilitation, medication review, assessment and correction of inhaler technique, nutritional advice, management of psycho-social issues, patient education, and management of co-morbidities.The primary outcome measure is health-related quality of life, assessed with the St George's Respiratory Questionnaire 12 months after diagnosis. Secondary outcome measures include validated disease-specific and general health related quality of life measures, smoking and immunisation status, medications, inhaler technique, and lung function. Outcomes will be assessed by project officers blinded to patients' randomization groups.
This study will use proven case-finding methods to identify patients with undiagnosed COPD in general practice, where improved care has the potential for substantial benefit in health and healthcare utilization. The study provides the capacity to trial a new model of team-based assessment and management of newly diagnosed COPD in Australian primary care.

[Show abstract][Hide abstract] ABSTRACT: To evaluate factors associated with the availability of same or next day appointments and after-hours access reported by Australian general practitioners (GPs).
Secondary analysis of a survey of primary care practitioners conducted by the Commonwealth Fund in 2009 in 11 countries. Analysis of factors likely to be associated with reported availability of same or next day appointments and after-hours access.
Of 1016 Australian GPs, 78.8% reported that most patients in their practice had access to an appointment on the same or next day and 50% that their practice had arrangements for after-hours access. Access to same or next day care was better in practices where practitioners reported larger numbers of patients seen per GP per week and reviewed their performance against annual targets, but worse in rural areas and practices routinely reviewing outcomes data. Arrangements for after-hours care were more common among GPs who were planning to retire in the next 5 years; worked in practices with high electronic functioning information systems; and received and reviewed clinical outcome data and incentives for performance.
Improving after-hours access requires a comprehensive approach which includes incentives, improvements to information management and organised systems of care with review of data on clinical outcomes.

[Show abstract][Hide abstract] ABSTRACT: Suboptimal uptake of anticoagulation for stroke prevention in atrial fibrillation has persisted for over 20 years, despite high-level evidence demonstrating its effectiveness in reducing the risk of fatal and disabling stroke.
The STOP STROKE in AF study is a national, cluster randomised controlled trial designed to improve the uptake of anticoagulation in primary care. General practitioners from around Australia enrolling in this 'distance education' program are mailed written educational materials, followed by an academic detailing session delivered via telephone by a medical peer, during which participants discuss patient de-identified cases. General practitioners are then randomised to receive written specialist feedback about the patient de-identified cases either before or after completing a three-month posttest audit. Specialist feedback is designed to provide participants with support and confidence to prescribe anticoagulation. The primary outcome is the proportion of patients with atrial fibrillation receiving oral anticoagulation at the time of the posttest audit.
The STOP STROKE in AF study aims to evaluate a feasible intervention via distance education to prevent avoidable stroke due to atrial fibrillation. It provides a systematic test of augmenting academic detailing with expert feedback about patient management.

[Show abstract][Hide abstract] ABSTRACT: Quality care of type 2 diabetes is complex and requires systematic use of clinical data to monitor care processes and outcomes. An electronic decision support (EDS) tool for the management of type 2 diabetes in primary care was developed by the Australian Pharmaceutical Alliance. The aim of this qualitative study was to evaluate the uptake and use of the EDS tool as well as to describe the impact of the EDS tool on the primary care consultation for diabetes from the perspectives of general practitioners and practice nurses.
This was a qualitative study of telephone interviews. General Practitioners and Practice Nurses from four Divisions of General Practice who had used the EDS tool for a minimum of six weeks were invited to participate. Semi-structured interviews were conducted and the interview transcripts were coded and thematically analysed using NVivo 8 software.
In total 15 General Practitioners and 2 Practice Nurses completed the interviews. The most commonly used feature of the EDS tool was the summary side bar; its major function was to provide an overview of clinical information and a prompt or reminder to diabetes care. It also assisted communication and served an educational role as a visual aide in the consultation. Some participants thought the tool resulted in longer consultations. There were a range of barriers to use related to the design and functionality of the tool and to the primary care context.
The EDS tool shows promise as a way of summarising information about patients' diabetes state, reminder of required diabetes care and an aide to patient education.

[Show abstract][Hide abstract] ABSTRACT: To evaluate the effectiveness of interventions used in primary care to improve health literacy for change in smoking, nutrition, alcohol, physical activity and weight (SNAPW).
A systematic review of intervention studies that included outcomes for health literacy and SNAPW behavioral risk behaviors implemented in primary care settings.We searched the Cochrane Library, Johanna Briggs Institute, Medline, Embase, CINAHL, Psychinfo, Web of Science, Scopus, APAIS, Australasian Medical Index, Google Scholar, Community of Science and four targeted journals (Patient Education and Counseling, Health Education and Behaviour, American Journal of Preventive Medicine and Preventive Medicine).Study inclusion criteria: Adults over 18 years; undertaken in a primary care setting within an Organisation for Economic Co-operation and Development (OECD) country; interventions with at least one measure of health literacy and promoting positive change in smoking, nutrition, alcohol, physical activity and/or weight; measure at least one outcome associated with health literacy and report a SNAPW outcome; and experimental and quasi-experimental studies, cohort, observational and controlled and non-controlled before and after studies.Papers were assessed and screened by two researchers (JT, AW) and uncertain or excluded studies were reviewed by a third researcher (MH). Data were extracted from the included studies by two researchers (JT, AW). Effectiveness studies were quality assessed. A typology of interventions was thematically derived from the studies by grouping the SNAPW interventions into six broad categories: individual motivational interviewing and counseling; group education; multiple interventions (combination of interventions); written materials; telephone coaching or counseling; and computer or web based interventions. Interventions were classified by intensity of contact with the subjects (High ≥ 8 points of contact/hours; Moderate >3 and <8; Low ≤ 3 points of contact hours) and setting (primary health, community or other).Studies were analyzed by intervention category and whether significant positive changes in SNAPW and health literacy outcomes were reported.
52 studies were included. Many different intervention types and settings were associated with change in health literacy (73% of all studies) and change in SNAPW (75% of studies). More low intensity interventions reported significant positive outcomes for SNAPW (43% of studies) compared with high intensity interventions (33% of studies). More interventions in primary health care than the community were effective in supporting smoking cessation whereas the reverse was true for diet and physical activity interventions.
Group and individual interventions of varying intensity in primary health care and community settings are useful in supporting sustained change in health literacy for change in behavioral risk factors. Certain aspects of risk behavior may be better handled in clinical settings while others more effectively in the community. Our findings have implications for the design of programs.
