Implementation of a primary-tertiary shared care model to improve the detection of familial hypercholesterolaemia (FH): a mixed methods pre-post implementation study protocol.

INTRODUCTION: Familial hypercholesterolaemia (FH) is an autosomal dominant inherited disorder of lipid metabolism and a preventable cause of premature cardiovascular disease. Current detection rates for this highly treatable condition are low. Early detection and management of FH can significantly reduce cardiac morbidity and mortality. This study aims to implement a primary-tertiary shared care model to improve detection rates for FH. The primary objective is to evaluate the implementation of a shared care model and support package for genetic testing of FH. This protocol describes the design and methods used to evaluate the implementation of the shared care model and support package to improve the detection of FH. METHODS AND ANALYSIS: This mixed methods pre-post implementation study design will be used to evaluate increased detection rates for FH in the tertiary and primary care setting. The primary-tertiary shared care model will be implemented at NSW Health Pathology and Sydney Local Health District in NSW, Australia, over a 12-month period. Implementation of the shared care model will be evaluated using a modification of the implementation outcome taxonomy and will focus on the acceptability, evidence of delivery, appropriateness, feasibility, fidelity, implementation cost and timely initiation of the intervention. Quantitative pre-post and qualitative semistructured interview data will be collected. It is anticipated that data relating to at least 62 index patients will be collected over this period and a similar number obtained for the historical group for the quantitative data. We anticipate conducting approximately 20 interviews for the qualitative data. ETHICS AND DISSEMINATION: Ethical approval has been granted by the ethics review committee (Royal Prince Alfred Hospital Zone) of the Sydney Local Health District (Protocol ID: X23-0239). Findings will be disseminated through peer-reviewed publications, conference presentations and an end-of-study research report to stakeholders.

Increasing screening for atrial fibrillation in general practice: the Atrial Fibrillation Self-Screening, Management And guideline-Recommended Therapy (AF Self-SMART) study.

OBJECTIVE: To assess whether atrial fibrillation (AF) self-screening stations in general practice waiting rooms improve AF screening, diagnosis, and stroke risk management. DESIGN, SETTING: Intervention study (planned duration: twelve weeks) in six New South Wales general practices (two in rural locations, four in greater metropolitan Sydney), undertaken during 28 August 2020 - 5 August 2021. PARTICIPANTS: People aged 65 years or more who had not previously been diagnosed with AF, and had appointments for face-to-face GP consultations. People with valvular AF were excluded. INTERVENTION: AF self-screening station and software, integrated with practice electronic medical record programs, that identified and invited participation by eligible patients, and exported single-lead electrocardiograms and automated evaluations to patients' medical records. MAIN OUTCOME MEASURES: Screening rate; incidence of newly diagnosed AF during intervention and pre-intervention periods; prescribing of guideline-recommended anticoagulant medications. RESULTS: Across the six participating practices, 2835 of 7849 eligible patients (36.1%) had face-to-face GP appointments during the intervention period, of whom 1127 completed AF self-screening (39.8%; range by practice: 12-74%). AF was diagnosed in 49 screened patients (4.3%), 44 of whom (90%) had CHA2 DS2 -VA scores of 2 or more (high stroke risk). The incidence of newly diagnosed AF during the pre-intervention period was 11 cases per 1000 eligible patients; during the intervention period, it was 22 per 1000 eligible patients (screen-detected: 17 per 1000 eligible patients; otherwise detected: 4.6 per 1000 eligible patients). Prescribing of oral anticoagulation therapy for people newly diagnosed with AF and high stroke risk was similar during the pre-intervention (20 of 24, 83%) and intervention periods (46 of 54, 85%). CONCLUSIONS: AF self-screening in general practice waiting rooms is a feasible approach to increasing AF screening and diagnosis rates by reducing time barriers to screening by GPs. AF self-screening could reduce the number of AF-related strokes. TRIAL REGISTRATION: Australian New Zealand Clinical Trials Registry ACTRN12620000233921 (prospective).

Development of a COVID-19 virtual community of practice in New South Wales: A qualitative study.

BACKGROUND AND OBJECTIVES: In April 2020, a group of general practice leaders in NSW, Australia, established a COVID-19 virtual community of practice (VCoP) to facilitate rapid transfer and implementation of clinical guidance into practice. This research aimed to gain an understanding of the experience and effectiveness of the VCoP from leaders and members. METHOD: The study used a qualitative participatory action research methodology. A framework analysis was applied to focus group discussion, semi-structured interview and open-text written response data. RESULTS: Thirty-six participants contributed data. In addition to a positive evaluation of the effectiveness of information transfer and support, a key finding was the importance of the role of the VCoP in professional advocacy. Areas for improvement included defining measures of success. DISCUSSION: This study has reinforced the potential for VCoPs to aid health crisis responses. In future crisis applications, we recommend purposefully structuring advocacy and success measures at VCoP establishment.

Implications of new clinical practice guidance on familial hypercholesterolaemia for Australian general practitioners.

BACKGROUND: Familial hypercholesterolaemia (FH) is a monogenic lipid disorder that may be overlooked in the diagnostic process. OBJECTIVE: The aim of this article is to review the key areas for identification and management of FH that affect Australian general practitioners (GPs). DISCUSSION: Recent consensus advice on the care of patients with FH in Australia provides an opportunity for GPs to increase their awareness and skills in diagnosing and managing FH. New Medicare Benefits Schedule items for genetic testing and Pharmaceutical Benefits Scheme listing for the use of proprotein convertase subtilisin/kexin 9 (PCSK9) inhibitors offer GPs additional supports to improve the care of patients with FH. A shared-care approach between GPs and non-GP specialists with expertise in multiple disciplines offers the best option to facilitate genetic testing and management of index cases and affected family relatives. Implementation of this guidance in the primary care setting remains an ongoing challenge and needs to be embraced as a high priority.

Awareness of familial hypercholesterolaemia in Australian primary care: A qualitative descriptive study.

BACKGROUND AND OBJECTIVES: A lack of public and health professional awareness about familial hypercholesterolaemia (FH) leads to an estimated 90,000 Australians remaining undiagnosed. The aim of this study was to establish the level of knowledge and awareness of FH in Australian general practices. METHOD: A qualitative descriptive methodology was used to explore baseline knowledge and perceptions of practice staff about diagnosing and managing FH. Overall, 63 interviews were conducted with general practice staff at 15 practices taking part in a National Health and Medical Research Council partnership grant study (GNT1142883). RESULTS: Data were analysed thematically and coded into themes - knowledge/awareness/recall, management, use of guidelines/referrals, and contacting family members. Most general practitioners treated the high cholesterol component as their primary focus. Guidelines and referrals were rarely used. DISCUSSION: This research reflected a lack of knowledge, awareness and use of guidelines similar to that shown in other published studies. Improved primary care infrastructure, knowledge and awareness of FH need to be addressed.

Impact of allergic rhinitis on the day-to-day lives of children: insights from an Australian cross-sectional study.

STUDY DESIGN AND OBJECTIVE: Cross-sectional, observational survey to describe the impact of allergic rhinitis (AR) on Australian children (2 to 15 years). METHODS: Participants (n=1541), parents of children aged 2 to 15 years, provided information on behalf of themselves and one eligible child in their household using a custom-built online questionnaire. Children were allocated to case (AR) or control (No AR) analysis groups based on a validated screening questionnaire. STATISTICAL METHODS: The study sample was stratified on age: primary analysis population (6 to 15 years, n=1111; AR=797, No AR=314); exploratory population (2 to 5 years). The primary endpoint, parent-perceived burden, was quantified using a validated measure of health status and analysed via comparison of means. RESULTS: The majority of AR cases were treated (730/797; 90.3%) and classified as having moderate-severe, intermittent AR (549/797; 68.9%). Half reported adequate symptom control in the prior 2 weeks (389/797; 48.8%; OR=4.04; 95% CI (CI) 2.24 to 7.31). Having AR was associated with worse overall health status (7.4 vs 8.4, mean difference (least squares mean difference (LSMD))=-0.99; 95% CI -1.18 to -0.79), fewer days being happy (22.2 vs 25.9, LSMD=-3.68; 95% CI -4.82 to -2.54) and more days of poor physical (2.82 vs 0.78, LSMD=2.04; 95% CI 1.61 to 2.47) and emotional (2.14 vs 0.67, LSMD=1.47; 95% CI 1.02 to -1.92) health compared with not having AR. All of these outcomes were significantly (p<0.05) worse in children who reported inadequate symptom control. Having AR negatively impacted on schoolwork, sleep and other activities, and increased the likelihood of having comorbidities. CONCLUSION: The parent-perceived burden of AR in Australian children is high and it impacts many areas of day-to-day living. Inadequate symptom control is a key driver of the extent of this impact. Opportunities to optimise the management of AR in children include the adoption of self-assessment tools to gauge and monitor adequacy of symptom control.

Atrial Fibrillation Screen, Management And Guideline Recommended Therapy (AF SMART II) in the rural primary care setting: an implementation study protocol.

INTRODUCTION: Screening for atrial fibrillation (AF) in people ≥65 years is now recommended by guidelines and expert consensus. While AF is often asymptomatic, it is the most common heart arrhythmia and is associated with increased risk of stroke. Early identification and treatment with oral anticoagulants can substantially reduce stroke risk. The general practice setting is ideal for opportunistic screening and provides a natural pathway for treatment for those identified.This study aims to investigate the feasibility of implementing screening for AF in rural general practice using novel electronic tools. It will assess whether screening will fit within an existing workflow to quickly and accurately identify AF, and will potentially inform a generalisable, scalable approach. METHODS AND ANALYSIS: Screening with a smartphone ECG will be conducted by general practitioners and practice nurses in rural general practices in New South Wales, Australia for 3-4 months during 2018-2019. Up to 10 practices will be recruited, and we aim to screen 2000 patients aged ≥65 years. Practices will be given an electronic screening prompt and electronic decision support to guide evidence-based treatment for those with AF. De-identified data will be collected using a clinical audit tool and qualitative interviews will be conducted with selected practice staff. A process evaluation and cost-effectiveness analysis will also be undertaken. Outcomes include implementation success (proportion of eligible patients screened, fidelity to protocol), proportion of people screened identified with new AF and rates of treatment with anticoagulants and antiplatelets at baseline and completion. Results will be compared against an earlier metropolitan study and a 'control' dataset of practices. ETHICS AND DISSEMINATION: Ethics approval was received from the University of Sydney Human Research Ethics Committee on 27 February 2018 (Project no.: 2017/1017). Results will be disseminated through various forums, including peer-reviewed publication and conference presentations. TRIAL REGISTRATION NUMBER: ACTRN12618000004268; Pre-results.
