Characterizing magnetically focused contamination electrons by off-axis irradiation on an inline MRI-Linac.

PURPOSE: The aim of this study is to investigate off-axis irradiation on the Australian MRI-Linac using experiments and Monte Carlo simulations. Simulations are used to verify experimental measurements and to determine the minimum offset distance required to separate electron contamination from the photon field. METHODS: Dosimetric measurements were performed using a microDiamond detector, Gafchromic® EBT3 film, and MOSkinTM . Three field sizes were investigated including 1.9 × 1.9, 5.8 × 5.8, and 9.7 × 9.6 cm2 . Each field was offset a maximum distance, approximately 10 cm, from the central magnetic axis (isocenter). Percentage depth doses (PDDs) were collected at a source-to-surface distance (SSD) of 1.8 m for fields collimated centrally and off-axis. PDD measurements were also acquired at isocenter for each off-axis field to measure electron contamination. Monte Carlo simulations were used to verify experimental measurements, determine the minimum field offset distance, and demonstrate the use of a spoiler to absorb electron contamination. RESULTS: Off-axis irradiation separates the majority of electron contamination from an x-ray beam and was found to significantly reduce in-field surface dose. For the 1.9 × 1.9, 5.8 × 5.8, and 9.7 × 9.6 cm2 field, surface dose was reduced from 120.9% to 24.9%, 229.7% to 39.2%, and 355.3% to 47.3%, respectively. Monte Carlo simulations generally were within experimental error to MOSkinTM and microDiamond, and used to determine the minimum offset distance, 2.1 cm, from the field edge to isocenter. A water spoiler 2 cm thick was shown to reduce electron contamination dose to near zero. CONCLUSIONS: Experimental and simulation data were acquired for a range of field sizes to investigate off-axis irradiation on an inline MRI-Linac. The skin sparing effect was observed with off-axis irradiation, a feature that cannot be achieved to the same extent with other methods, such as bolusing, for beams at isocenter.

Effectiveness of Primary Health Care Services in Addressing Mental Health Needs of Minority Refugee Population in New Zealand.

Many people are displaced from their country of origin and become refugees, mostly due to armed conflicts, political violence and human rights abuse. Refugees have complex mental, physical, and social health problems related to their traumatic background and the experiences they have endured during their refugee journey. The aim of this qualitative exploratory study was to examine the effectiveness of primary health care services in addressing mental health needs of Bhutanese refugee women resettled in New Zealand. This study included focus group discussion with Bhutanese women and men followed by interviews with health service providers. The findings of this study highlighted inadequacies and constraints in addressing Bhutanese refugee women's mental health needs in New Zealand and provided evidence for recommendations to address these inadequacies.

Responding to Young People's Health Risks in Primary Care: A Cluster Randomised Trial of Training Clinicians in Screening and Motivational Interviewing.

OBJECTIVE: To evaluate the effectiveness of a complex intervention implementing best practice guidelines recommending clinicians screen and counsel young people across multiple psychosocial risk factors, on clinicians' detection of health risks and patients' risk taking behaviour, compared to a didactic seminar on young people's health. DESIGN: Pragmatic cluster randomised trial where volunteer general practices were stratified by postcode advantage or disadvantage score and billing type (private, free national health, community health centre), then randomised into either intervention or comparison arms using a computer generated random sequence. Three months post-intervention, patients were recruited from all practices post-consultation for a Computer Assisted Telephone Interview and followed up three and 12 months later. Researchers recruiting, consenting and interviewing patients and patients themselves were masked to allocation status; clinicians were not. SETTING: General practices in metropolitan and rural Victoria, Australia. PARTICIPANTS: General practices with at least one interested clinician (general practitioner or nurse) and their 14-24 year old patients. INTERVENTION: This complex intervention was designed using evidence based practice in learning and change in clinician behaviour and general practice systems, and included best practice approaches to motivating change in adolescent risk taking behaviours. The intervention involved training clinicians (nine hours) in health risk screening, use of a screening tool and motivational interviewing; training all practice staff (receptionists and clinicians) in engaging youth; provision of feedback to clinicians of patients' risk data; and two practice visits to support new screening and referral resources. Comparison clinicians received one didactic educational seminar (three hours) on engaging youth and health risk screening. OUTCOME MEASURES: Primary outcomes were patient report of (1) clinician detection of at least one of six health risk behaviours (tobacco, alcohol and illicit drug use, risks for sexually transmitted infection, STI, unplanned pregnancy, and road risks); and (2) change in one or more of the six health risk behaviours, at three months or at 12 months. Secondary outcomes were likelihood of future visits, trust in the clinician after exit interview, clinician detection of emotional distress and fear and abuse in relationships, and emotional distress at three and 12 months. Patient acceptability of the screening tool was also described for the intervention arm. Analyses were adjusted for practice location and billing type, patients' sex, age, and recruitment method, and past health risks, where appropriate. An intention to treat analysis approach was used, which included multilevel multiple imputation for missing outcome data. RESULTS: 42 practices were randomly allocated to intervention or comparison arms. Two intervention practices withdrew post allocation, prior to training, leaving 19 intervention (53 clinicians, 377 patients) and 21 comparison (79 clinicians, 524 patients) practices. 69% of patients in both intervention (260) and comparison (360) arms completed the 12 month follow-up. Intervention clinicians discussed more health risks per patient (59.7%) than comparison clinicians (52.7%) and thus were more likely to detect a higher proportion of young people with at least one of the six health risk behaviours (38.4% vs 26.7%, risk difference [RD] 11.6%, Confidence Interval [CI] 2.93% to 20.3%; adjusted odds ratio [OR] 1.7, CI 1.1 to 2.5). Patients reported less illicit drug use (RD -6.0, CI -11 to -1.2; OR 0.52, CI 0.28 to 0.96), and less risk for STI (RD -5.4, CI -11 to 0.2; OR 0.66, CI 0.46 to 0.96) at three months in the intervention relative to the comparison arm, and for unplanned pregnancy at 12 months (RD -4.4; CI -8.7 to -0.1; OR 0.40, CI 0.20 to 0.80). No differences were detected between arms on other health risks. There were no differences on secondary outcomes, apart from a greater detection of abuse (OR 13.8, CI 1.71 to 111). There were no reports of harmful events and intervention arm youth had high acceptance of the screening tool. CONCLUSIONS: A complex intervention, compared to a simple educational seminar for practices, improved detection of health risk behaviours in young people. Impact on health outcomes was inconclusive. Technology enabling more efficient, systematic health-risk screening may allow providers to target counselling toward higher risk individuals. Further trials require more power to confirm health benefits. TRIAL REGISTRATION: ISRCTN.com ISRCTN16059206.

Factors associated with relational coordination between health professionals involved in insulin initiation in the general practice setting for people with type 2 diabetes.

AIM: To examine associations between characteristics of general practice settings and primary healthcare providers (general practitioners and practice nurses) and the degree of relational coordination for the task of insulin initiation for type 2 diabetes between primary healthcare providers and diabetes specialists. BACKGROUND: Relational coordination is a component of effective chronic disease management and can be used to measure collaboration and communication between health professionals. High levels of relational coordination may be important to support insulin initiation in general practice. DESIGN: Cross-sectional study. METHODS: Surveys were completed by general practitioners and practice nurses participating in the Stepping Up trial. Data on demographics, practice characteristics and relational coordination were collected between October 2012-June 2014. Univariate and multivariate analyses examined factors associated with relational coordination. RESULTS: General practitioners (n = 174) and 115 practice nurses from 78 general practices were included in the analysis. General practice characteristics associated with relational coordination were geographical location and number of administrative staff. Female general practitioners and older practice nurses reported lower relational coordination. Practice nurses with diabetes educator qualifications and experience in insulin initiation reported higher relational coordination. CONCLUSION: An expanded role and experience of practice nurses in diabetes care increased relational coordination and has the potential to deliver more effective chronic disease management in general practice. Practice and health professional characteristics should be taken into account when designing models of care to increase insulin initiation.

Relational coordination amongst health professionals involved in insulin initiation for people with type 2 diabetes in general practice: an exploratory survey.

BACKGROUND: The majority of people with type 2 diabetes (T2D) receive their care in general practice and will eventually require initiation of insulin as part of their management. However, this is often delayed and frequently involves referral to specialists. If insulin initiation is to become more frequent and routine within general practice, coordination of care with specialist services may be required. Relational coordination (RC) provides a framework to explore this. The aim of this study was to explore RC between specialist physicians, specialist diabetes nurses (DNEs), generalist physicians in primary care (GPs) and generalist nurses (practice nurses (PNs)) and to explore the association between RC and the initiation of insulin in general practice, and the belief that it is appropriate for this task to be carried out in general practice. METHODS: A survey was distributed to a convenience sample of specialist physicians, DNEs, GPs and practice nurses. We collected data on demographics, models of care and RC in relation to insulin initiation. We expected that RC would be higher between specialists than between specialists and generalists. We expected higher RC between specialists and generalists to be associated with insulin initiation in general practice and with the belief that it is appropriate for insulin initiation to be carried out in general practice. We used descriptive statistics and non-parametric tests to explore these hypotheses. RESULTS: 179 health professionals returned completed surveys. Specialists reported higher RC with each other and lower RC with PNs. All groups except PNs reported their highest RC with DNEs, suggesting the potential for DNEs to serve as boundary spanners. Lower RC with specialists was reported by those working within a general practice model of care. Health professionals who felt that a general practice model was appropriate reported lower communication with specialist physicians and higher shared knowledge with GPs. CONCLUSION: Given the need for coordination between specialist and generalist care for the task of insulin initiation, this study's results suggest the need to build relationships and communication between specialist and generalist health professional groups and the potential for DNE's to play a boundary spanner role in this process.

Revenue effects of practice nurse-led care for chronic diseases.

OBJECTIVE: To determine the economic feasibility in Australian general practices of using a practice nurse (PN)-led care model of chronic disease management. METHODS: A cost-analysis of item numbers from the Medicare Benefit Schedule (MBS) was performed in three Australian general practices, one urban, one regional and one rural. Patients (n =254; >18 years of age) with chronic conditions (type 2 diabetes, hypertension, ischaemic heart disease) but without unstable or major health problems were randomised into usual general practitioner (GP) or PN-led care for management of their condition over a period of 12 months. After the 12-month intervention, total MBS item charges were evaluated for patients managed for their stable chronic condition by usual GP or PN-led care. Zero-skewness log transformation was applied to cost data and log-linear regression analysis was undertaken. RESULTS: There was an estimated A$129 mean increase in total MBS item charges over a 1-year period (controlled for age, self-reported quality of life and geographic location of practice) associated with PN-led care. The frequency of GP and PN visits varied markedly according to the chronic disease. CONCLUSIONS: Medicare reimbursements provided sufficient funding for general practices to employ PNs within limits of workloads before the new Practice Nurse Incentive Program was introduced in July 2012.

Can primary care team-based transition to insulin improve outcomes in adults with type 2 diabetes: the stepping up to insulin cluster randomized controlled trial protocol.

BACKGROUND: Type 2 diabetes (T2D) brings significant human and healthcare costs. Its progressive nature means achieving normoglycaemia is increasingly difficult, yet critical to avoiding long term vascular complications. Nearly one-half of people with T2D have glycaemic levels out of target. Insulin is effective in achieving glycaemic targets, yet initiation of insulin is often delayed, particularly in primary care. Given limited access to specialist resources and the size of the diabetes epidemic, primary care is where insulin initiation must become part of routine practice. This would also support integrated holistic care for people with diabetes. Our Stepping Up Program is based on a general practitioner (GP) and practice nurse (PN) model of care supported appropriately by endocrinologists and credentialed diabetes educator-registered nurses. Pilot work suggests the model facilitates integration of the technical work of insulin initiation within ongoing generalist care. METHODS: This protocol is for a cluster randomized controlled trial to examine the effectiveness of the Stepping Up Program to enhance the role of the GP-PN team in initiating insulin and improving glycaemic outcomes for people with T2D. 224 patients between the ages of 18 and 80 years with T2D, on two or more oral hypoglycaemic agents and with an HbA1c ≥7.5% in the last six months will be recruited from 74 general practices. The unit of randomization is the practice.Primary outcome is change in glycated haemoglobin HbA1c (measured as a continuous variable). We hypothesize that the intervention arm will achieve an absolute HbA1c mean difference of 0.5% lower than control group at 12 months follow up. Secondary outcomes include the number of participants who successfully transfer to insulin and the proportion who achieve HbA1c measurement of <7.0%. We will also collect data on patient psychosocial outcomes and healthcare utilization and costs. DISCUSSION: The study is a pragmatic translational study with important potential implications for people with T2D, healthcare professionals and funders of healthcare though making better use of scarce healthcare resources, improving timely access to therapy that can improve disease outcomes.

Roles and relationships between health professionals involved in insulin initiation for people with type 2 diabetes in the general practice setting: a qualitative study drawing on relational coordination theory.

BACKGROUND: The majority of care for people with type 2 diabetes occurs in general practice, however when insulin initiation is required it often does not occur in this setting or in a timely manner and this may have implications for the development of complications. Increased insulin initiation in general practice is an important goal given the increasing prevalence of type 2 diabetes and a relative shortage of specialists. Coordination between primary and secondary care, and between medical and nursing personnel, may be important in achieving this. Relational coordination theory identifies key concepts that underpin effective interprofessional work: communication which is problem solving, timely, accurate and frequent and relationships between professional roles which are characterized by shared goals, shared knowledge and mutual respect. This study explores roles and relationships between health professionals involved in insulin initiation in order to gain an understanding of factors which may impact on this task being carried out in the general practice setting. METHOD: 21 general practitioners, practice nurses, diabetes nurse educators and physicians were purposively sampled to participate in a semi-structured interview. Transcripts of the interviews were analysed using framework analysis. RESULTS: There were four closely interlinked themes identified which impacted on how health professionals worked together to initiate people with type 2 diabetes on insulin: 1. Ambiguous roles; 2. Uncertain competency and capacity; 3. Varying relationships and communication; and 4. Developing trust and respect. CONCLUSIONS: This study has shown that insulin initiation is generally recognised as acceptable in general practice. The role of the DNE and practice nurse in this space and improved communication and relationships between health professionals across organisations and levels of care are factors which need to be addressed to support this clinical work. Relational coordination provides a useful framework for exploring these issues.

Uptake of Medicare chronic disease management incentives - a study into service providers' perspectives.

BACKGROUND: Chronic disease is responsible for 80% of the burden of disease in Australia. The Australian Government Medicare Benefits Schedule (MBS) provides incentives through specific Medicare items to optimise chronic disease management (CDM), yet little is known about factors that influence their uptake. METHODS: Exploratory qualitative research was used, which incorporated focus groups and interviews with 26 staff from nine general practices in southeast Queensland, together with review of practice-specific data on CDM income. Content analysis of qualitative data was undertaken to identify barriers, enablers and service models associated with MBS CDM item uptake. Triangulation of methods and data sources facilitated confirmation of findings. RESULTS: Time pressures and unreliable MBS information were common barriers to uptake for general practitioners. Employing a nurse, team-based approaches, recall systems and using only selected MBS CDM item numbers were associated with best uptake. CONCLUSION: Improved systems within general practice and Medicare may increase the uptake of MBS CDM item numbers.

The prevention access and risk taking in young people (PARTY) project protocol: a cluster randomised controlled trial of health risk screening and motivational interviewing for young people presenting to general practice.

BACKGROUND: There are growing worldwide concerns about the ability of primary health care systems to manage the major burden of illness in young people. Over two thirds of premature adult deaths result from risks that manifest in adolescence, including injury, neuropsychiatric problems and consequences of risky behaviours. One policy response is to better reorientate primary health services towards prevention and early intervention. Currently, however, there is insufficient evidence to support this recommendation for young people. This paper describes the design and implementation of a trial testing an intervention to promote psychosocial risk screening of all young people attending general practice and to respond to identified risks using motivational interviewing. MAIN OUTCOMES: clinicians' detection of risk-taking and emotional distress, young people's intention to change and reduction of risk taking. SECONDARY OUTCOMES: pathways to care, trust in the clinician and likelihood of returning for future visits. The design of the economic and process evaluation are not detailed in this protocol. METHODS: PARTY is a cluster randomised trial recruiting 42 general practices in Victoria, Australia. Baseline measures include: youth friendly practice characteristics; practice staff's self-perceived competency in young people's care and clinicians' detection and response to risk taking behaviours and emotional distress in 14-24 year olds, attending the practice. Practices are then stratified by a social disadvantage index and billing methods and randomised. Intervention practices receive: nine hours of training and tools; feedback of their baseline data and two practice visits over six weeks. Comparison practices receive a three hour seminar in youth friendly practice only. Six weeks post-intervention, 30 consecutive young people are interviewed post-consultation from each practice and followed-up for self-reported risk taking behaviour and emotional distress three and 12 months post consultation. DISCUSSION: The PARTY trial is the first to examine the effectiveness and efficiency of a psychosocial risk screening and counselling intervention for young people attending primary care. It will provide important data on health risk profiles of young people attending general practice and on the effects of the intervention on engagement with primary care and health outcomes over 12 months.

Clinical handover of patients arriving by ambulance to the emergency department - a literature review.

AIM: To provide a critical review of research on clinical handover between the ambulance service and emergency department (ED) in hospitals. METHOD: Data base and hand searches were conducted using the keywords ambulance, handover, handoff, emergency department, emergency room, ER, communication, and clinical handover. Data were extracted, summarised and critically assessed to provide evidence of current clinical handover processes. RESULTS: From 252 documents, eight studies fitted the inclusion criteria of clinical handover and the ambulance to ED patient transfer. Three themes were identified in the review: (1) important information may be missed during clinical handover; (2) structured handovers that include both written and verbal components may improve information exchange; (3) multidisciplinary education about the clinical handover process may encourage teamwork, a shared common language and a framework for minimum patient information to be transferred from the ambulance service to the hospital ED. CONCLUSION: Knowledge gaps exist concerning handover information, consequences of poor handover, transfer of responsibility, staff perception of handovers, staff training and evaluation of recommended strategies to improve clinical handover. Evidence of strategies being implemented and further research is required to examine the ongoing effects of implementing the strategies.

Experiences of graduate Registered Nurses in aged care: a case study.

The number of Registered Nurses (RNs) working in aged care is declining, with few new RNs choosing aged care in their graduate year. This paper describes a study exploring 11 female graduate RNs' experiences of working in an aged care setting in Victoria, Australia to assist in informing recruitment and retention strategies in aged care. Semi-structured interviews were undertaken and thematically analysed using open coding. This paper presents findings related to the themes of 'free choice or allocated to aged care' 'reasons for graduate choices', 'nature of aged care: a match or mismatch for graduates', 'lack of professional support for graduate RNs in aged care' and 'role confusion'. Findings supported the recruitment of graduate RNs with an initial interest in aged care into the sector. A clearer definition of the new graduate RN's role in aged care and a standardised graduate program may assist in increasing retention of such nurses in the future.

General surgical patients' perspectives of the adequacy and appropriateness of discharge planning to facilitate health decision-making at home.

AIM: To investigate general surgical patients' perspectives of the adequacy and appropriateness of their discharge planning. OBJECTIVES: To identify any aspects of discharge planning that could be strengthened to assist people in managing their posthospital care and maintaining continuity of care. BACKGROUND: Appropriate discharge planning is a priority in today's healthcare environment in which patients are discharged 'quicker and sicker', sometimes without home support. Adequate and appropriate discharge planning helps promote health literacy, which has benefits for both patients and their caregivers in helping them manage postsurgical recovery at home. DESIGN: A qualitative, interpretive study was designed in which patients were interviewed at least one week after they returned home from hospital. METHODS: Purposeful sampling was used to interview 13 general surgical patients from one of three hospitals (two public and one private) in New South Wales and Queensland, Australia. Data were collected in unstructured interviews and analysed using thematic analysis. Reflective analysis by individual research team members generated preliminary themes, which were then analysed collectively by all members of the research team to achieve consensus on patients' perspectives. RESULTS: Themes included a 'one-size-fits-all' approach to providing discharge information; inconsistent or variable advice from different health professionals; a lack of predischarge assessment of their home and/or work conditions and the need for follow-up assessment of patient and carer needs. CONCLUSIONS: The findings of this study illuminate the need for a more individualized approach to discharge planning, taking into account the patient's age, gender, surgical procedure and family and community support for immediate and longer-term nursing follow-up. RELEVANCE TO CLINICAL PRACTICE: Patients would be more adequately prepared for their recovery period at home, by encouraging client-centred, interdisciplinary communication between health practitioners; adopting a flexible, approach to discharge planning which is tailored to individual needs of postsurgical patients, particularly in relation to advice and information related to recovery; and encouraging and supporting adequate health literacy for self-management.

Evolution of practice nursing in Australia.

AIM: This paper describes the evolution of Australian practice nursing and documents seminal events in crystallizing the importance of the nursing role in general practice. BACKGROUND: Internationally, the potential for nurses to improve health in primary care settings is acknowledged. The general practice setting is a focal point for primary care in many health systems. Despite the important role played in the delivery of primary health care by nurses working in general practice in the United Kingdom and New Zealand, the role of nurses in Australian general practice is much less clearly defined, as reflected by the paucity of research and scholarship in this area. Fuelled by the increasing challenges of workforce shortages and the increasing need for multidisciplinary care, interest in the developing role of the Australian practice nurse among clinicians, researchers and policy makers is increasing. DISCUSSION: Australian practice nursing has reached a critical point in its evolution. It is imperative for the promotion of nursing in general practice that knowledge from descriptive, exploratory research be used to inform strategic decision-making in terms of professional development issues, policy, research and scholarship. These data also need to inform systematic outcome studies. To date, the embryonic nature of practice nursing as a discrete professional entity in Australia has inhibited its representation in nursing curricula and professional bodies. CONCLUSION: In order to advance the Australian practice nurse movement and demonstrate its important contribution to primary health care, nurses need to take the lead in strategic planning of this emerging specialty. As well as leadership from an academic, research and policy perspective, clinical leaders need to be fostered among the ranks of practice nurse clinicians to drive clinical practice development and the delivery of evidence-based primary care.

Being strategic: utilising consumer views to better promote an expanded role for nurses in Australian general practice.

Australian consumers have articulated their perceptions of the role of the nurse in general practice. Practice Nurses (PNs) and General Practitioners (GPs) have also highlighted the issues they believe currently and potentially impact on this role in Australia. This paper identifies and discusses the nexus between the consumers' perceptions and expectations and health professionals' issues. Data collected from focus groups and interviews in 2 Australian studies of consumer perception of nursing in general practice, are re-considered alongside findings reported in the Royal Australian College of General Practitioners and the Royal College of Nursing, Australia report; General Practice Nursing in Australia. Consumers, doctors and nurses working in general practices in Australia, raised similar issues. However, consumers considered these issues in relation to their health care needs, whereas the GPs and PNs tended to focus more on professional and structural tensions related to the current and potentially expanded role of the PN. Understanding consumer views vis-a-vis issues raised by PNs and GPs about the role of nursing in general practice provides direction for both professions to better work with consumers to enhance their understanding of what general practice services could be and how changes, like expanding the role of nurses, may bring about improvements in the health outcomes of consumers. Health professionals can benefit from reflecting on the experiences and expectations of consumers if they desire to make general practice services more responsive to individual consumer's needs and at the same time adopt a primary health care focus.

Risk reduction in general practice and the role of the receptionist.

Medical receptionists play a crucial role in any practice as they are usually the first points of contact for patients and the intermediaries through whom contacts with medical practitioners are made. This article reports the findings of a qualitative study of medical receptionists undertaken to explore their role in general practice, particularly in relation to activities involving direct patient assessment, monitoring, counselling and therapy. The findings highlight a number of significant issues in relation to the potential liability of receptionists, medical practitioners, medical centre owners and insurers.
