ItemHave interventions aimed at assisting general practitioners in facilitating earlier diagnosis of type 1 diabetes in children been successful? A systematic review protocol(BMJ PUBLISHING GROUP, 2023-12)BACKGROUND: Early diagnosis of type 1 diabetes in children is critical to prevent deterioration to diabetic ketoacidosis (DKA), a state where the body's insulin levels are critically low resulting in the use of fat for fuel and the accumulation of ketones. DKA is a life-threatening emergency where dehydration and cerebral oedema can quickly develop and lead to death. Despite treatment, DKA also has harmful impacts on cognition and brain development. Most children admitted to a hospital with DKA see their general practitioner in the week leading up to their admission. A delay in referral from general practice can result in delays in commencing lifesaving insulin therapy. Prior systematic reviews have explored publicity campaign interventions aimed at recognising type 1 diabetes earlier; however, no reviews have explored these interventions targeted at reducing the delay after presentation to the general practitioner. This systematic review aims to summarise interventions that target the diagnostic delay emerging from general practice and to evaluate their effectiveness in reducing DKA admissions. METHODS: Six databases (Ovid (MEDLINE), Web of Science, EMBASE, CINAHL, Evidence-Based Medicine Reviews (EBMR) and Google Scholar) will be searched to identify studies exploring interventions to reduce diagnostic delay in children with type 1 diabetes, and hence DKA, in general practice. The primary outcome will be the number of DKA admissions to a hospital following a delay in general practice. The secondary outcome will be the behaviour of general practitioners with respect to urgent referral of children with type 1 diabetes. Title, abstract and full-text screening for exclusion and inclusion of publications will be completed by two independent reviewers. Any risks of bias within individual studies will be assessed by two independent reviewers, using the Risk Of Bias In Non-Randomized Studies of Interventions tool. Our confidence in the overall body of evidence will be assessed using the Grading of Recommendations, Assessment, Development and Evaluation. ETHICS AND DISSEMINATION: The systematic review will be disseminated via publication and potentially in conference presentations. Ethics is not required for a systematic review of secondary data. PROSPERO REGISTRATION NUMBER: CRD42023412504.

ItemChronic disease IMPACT (chronic disease early detection and improved management in primary care project): An Australian stepped wedge cluster randomised trial(SAGE PUBLICATIONS LTD, 2023)BACKGROUND: Interrelated chronic vascular diseases (chronic kidney disease (CKD), type 2 diabetes (T2D) and cardiovascular disease (CVD)) are common with high morbidity and mortality. This study aimed to assess if an electronic-technology-based quality improvement intervention in primary care could improve detection and management of people with and at risk of these diseases. METHODS: Stepped-wedge trial with practices randomised to commence intervention in one of five 16-week periods. Intervention included (1) electronic-technology tool extracting data from general practice electronic medical records and generating graphs and lists for audit; (2) education regarding chronic disease and the electronic-technology tool; (3) assistance with quality improvement audit plan development, benchmarking, monitoring and support. De-identified data analysis using R 3.5.1 conducted using Bayesian generalised linear mixed model with practice and time-specific random intercepts. RESULTS: At baseline, eight included practices had 37,946 active patients (attending practice ≥3 times within 2 years) aged ≥18 years. Intervention was associated with increased OR (95% CI) for: kidney health checks (estimated glomerular filtration rate, urine albumin:creatinine ratio (uACR) and blood pressure) in those at risk 1.34 (1.26-1.42); coded diagnosis of CKD 1.18 (1.09-1.27); T2D diagnostic testing (fasting glucose or HbA1c) in those at risk 1.15 (1.08-1.23); uACR in patients with T2D 1.78 (1.56-2.05). Documented eye checks within recommended frequency in patients with T2D decreased 0.85 (0.77-0.96). There were no significant changes in other assessed variables. CONCLUSIONS: This electronic-technology-based intervention in primary care has potential to help translate guidelines into practice but requires further refining to achieve widespread improvements across the interrelated chronic vascular diseases.

ItemFactors impacting COVID-19 vaccine decision making in older adults and people with underlying conditions in Victoria, Australia: A cross-sectional survey(TAYLOR & FRANCIS INC, 2022-12-30)Australia's COVID-19 vaccine rollout included prioritizing older adults and those with underlying conditions. However, little was known around the factors impacting their decision to accept the vaccine. This study aimed to assess vaccine intentions, information needs, and preferences of people prioritized to receive the COVID-19 vaccine at the start of the Australian vaccine rollout. A cross-sectional online survey of people aged ≥70 years or 18-69 with chronic or underlying conditions was conducted between 12 February and 26 March 2021 in Victoria, Australia. The World Health Organization Behavioural and Social Drivers of COVID-19 vaccination framework and items informed the survey design and framing of results. Bivariate logistic regression was used to investigate the association between intention to accept a COVID-19 vaccine and demographic characteristics. In total, 1828 eligible people completed the survey. Intention to vaccinate was highest among those ≥70 years (89.6%, n = 824/920) versus those aged 18-69 years (83.8%, n = 761/908), with 91% (n = 1641/1803) of respondents agreeing that getting a COVID-19 vaccine was important to their health. Reported vaccine safety (aOR 1.4, 95% CI 1.1 to 1.8) and efficacy (aOR 1.9, 95% CI 1.5 to 2.3) were associated with intention to accept a COVID-19 vaccine. Concerns around serious illness, long-term effects, and insufficient vaccine testing were factors for not accepting a COVID-19 vaccine. Preferred communication methods included discussion with healthcare providers, with primary care providers identified as the most trusted information source. This study identified factors influencing the prioritized public's COVID-19 vaccine decision-making, including information preferences. These details can support future vaccination rollouts.

ItemInforming the design of a digital intervention to support sexually transmissible infection care in general practice: a qualitative study exploring the views of clinicians(CSIRO Publishing, 2023)Background: Strengthening sexually transmissible infection (STI) management in general practice is prioritised in Australian STI strategy. Digital interventions incorporating clinical decision support offer a mechanism to assist general practitioners (GPs) in STI care. This study explored clinicians’ views towards a proposed digital intervention for supporting STI care in Australian general practice as a first step in the tool’s design. Methods: Semi-structured one-to-one interviews were conducted during 2021 with sexual health physicians (n = 2) and GPs (n = 7) practicing in the state of Victoria, Australia. Interviews explored views on a proposed STI digital intervention for general practice. We applied the Theoretical Domains Framework (TDF), a behaviour change framework to our analysis. This involved: (1) directed content analysis of transcripts into TDF domains; and (2) thematic analysis to identify sub-themes within relevant TDF domains. Subthemes were subsequently categorised into enablers and barriers to the use and implementation of a STI computerised clinical decision support system (CDSS). Results: All interviewees viewed a digital intervention for STI care favourably, expressing confidence in its potential to improve care and support management. Within the relevant TDF domains (e.g. environmental context and resources), subthemes emerged as barriers (e.g. lack of sensitivity to patient context) or enablers (e.g. clear communication and guidance) to the use and implementation of a STI CDSS in primary care. Multiple subthemes (e.g. time constraints) have the potential to be a barrier or an enabler, and is largely dependent on end-user needs being met and clinical context being appropriately addressed. Conclusions: A digital intervention incorporating clinical decision support was viewed favourably, indicating a possible role for such a tool in Australian general practice. Co-design with end-users and prototype evaluation with health consumers is recommended to ensure relevance and usefulness.

ItemSite-specific factors associated with clinical trial recruitment efficiency in general practice settings: a comparative descriptive analysis(BMC, 2023-03-04)BACKGROUND: Recruitment of participants is crucial to the success of randomised control trials (RCTs) but can be challenging and expensive. Current research on trial efficiency is often focused at the patient-level with an emphasis on effective recruitment strategies. Less is known about selection of study sites to optimise recruitment. We examine site-level factors that are associated with patient recruitment and cost efficiency using data from an RCT conducted across 25 general practices (GP) in Victoria, Australia. METHODS: Data on number of participants screened, excluded, eligible, recruited, and randomised from each study site were extracted from a clinical trial. Details regarding site characteristics, recruitment practices, and staff time commitment were collected using a three-part survey. The key outcomes assessed were recruitment efficiency (ratio of screened to randomised), average time, and cost for each participant recruited and randomised. To identify practice-level factors associated with efficient recruitment and lower cost, outcomes were dichotomised (25th percentile vs others) and each practice-level factor assessed against the outcomes to determine its association. RESULTS: Across 25 GP study sites, 1968 participants were screened of which 299 (15.2%) were recruited and randomised. The mean recruitment efficiency was 7.2, varying from 1.4 to 19.8 across sites. The strongest factor associated with efficiency was assigning clinical staff to identify potential participants (57.14% vs. 22.2%). The more efficient sites were smaller practices and were more likely to be rural locations and in areas of lower socioeconomic status. The average time used for recruitment was 3.7 h (SD2.4) per patient randomised. The mean cost per patient randomised was $277 (SD161), and this varied from $74 to $797 across sites. The sites identified with the 25% lowest recruitment cost (n = 7) were more experienced in research participation and had high levels of nurse and/or administrative support. CONCLUSION: Despite the small sample size, this study quantified the time and cost used to recruit patients and provides helpful indications of site-level characteristics that can help improve feasibility and efficiency of conducting RCT in GP settings. Characteristics indicative of high levels of support for research and rural practices, which often tends to be overlooked, were observed to be more efficient in recruiting.

ItemDeveloping and internally validating a prediction model for total knee replacement surgery in patients with osteoarthritis.(Elsevier BV, 2022-09)OBJECTIVE: The objective of this study was to develop and internally validate a clinical algorithm for use in general practice that predicts the probability of total knee replacement (TKR) surgery within the next five years for patients with osteoarthritis. The purpose of the model is to encourage early uptake of first-line treatment strategies in patients likely to undergo TKR and to provide a cohort for the development and testing of novel interventions that prevent or delay the progression to TKR. METHOD: Electronic health records (EHRs) from 201,462 patients with osteoarthritis aged 45 years and over from 483 general practices across Australia were linked with records from the Australian Orthopaedic Association National Joint Replacement Registry and the National Death Index. A Fine and Gray competing risk prediction model was developed using these data to predict the risk of TKR within the next five years. RESULTS: During a follow-up time of 5 years, 15,979 (7.9%) patients underwent TKR and 13,873 (6.9%) died. Predictors included in the final algorithm were age, previous knee replacement, knee surgery (other than TKR), prescribing of osteoarthritis medication in the 12 months prior, comorbidity count and diagnosis of a mental health condition. Optimism corrected model discrimination was 0.67 (95% CI: 0.66 to 0.67) and model calibration acceptable. CONCLUSION: The model has the potential to reduce some of the economic burden associated with TKR in Australia. External validation and further optimisation of the algorithm will be carried out prior to implementation within Australian general practice EHR systems.

ItemAssessing and addressing diabetes distress among adults with type 2 diabetes: An online survey of Australian general practitioners(ELSEVIER SCI LTD, 2022-10)AIM: Diabetes distress is experienced by up to 36% of adults with type 2 diabetes. Australian type 2 diabetes guidelines recommend annual assessment of diabetes distress in general practice. This study explores general practitioners' knowledge, current practice, and factors influencing implementation of guidelines, including Person Reported Outcome Measure (PROM) use. METHODS: A cross-sectional online survey was disseminated via e-mail to 4776 Australian general practitioners listed on the Australasian Medical Publishing Company database. RESULTS: 264 (5%) surveys were returned. 75% indicated that general practitioners were the most appropriate professionals to assess diabetes distress. Sixteen percent reported asking about diabetes distress during type 2 diabetes consultations more than half the time, with 13% using a PROM more than half the time: 64% use the Kessler-10, and 1.9% use the Problem Areas in Diabetes (PAID) scale. While general practitioners had positive beliefs about the consequences of assessing and addressing diabetes distress, they also reported barriers in motivation, environment, and knowledge of guidelines. CONCLUSION: Most respondents endorsed general practitioners' role in assessing diabetes distress, but few ask about or assess diabetes distress in routine consultations. To support uptake of guideline recommendations for diabetes-specific PROM use, environmental factors, specifically time, need to be addressed.

ItemPeople with type 2 diabetes' experiences of emotional support in Australian general practice: a qualitative study(ROYAL COLL GENERAL PRACTITIONERS, 2022-12)BACKGROUND: Diabetes distress, experienced by up to 40% of people with type 2 diabetes (T2D), is the negative emotional response to the burden of living with and managing diabetes. It is associated with suboptimal glycaemia and diabetes self-management. Research indicates that people with diabetes do not recall being asked about emotional distress by healthcare professionals. AIM: To explore the experiences, needs, and expectations of people with T2D regarding emotional support received in Australian general practice. DESIGN & SETTING: Exploratory qualitative study in Victoria, Australia. METHOD: Semi-structured interviews were undertaken to explore emotional health and support received in general practice in 12 adults with T2D who primarily attend general practice. Interviews were audio-recorded, transcribed verbatim, and analysed using the framework approach. RESULTS: The following three major themes were identified: (1) Beneath the surface of diabetes care; (2) Importance of GP-patient relationship; and (3) Communication counts. Participants experienced diabetes care as focused primarily on medical management rather than the emotional aspects of living with T2D. While people's experiences of diabetes care in general practice primarily focused on physical health, the GP care beyond the presenting complaint has an essential role in identifying emotional issues and enabling support. Emotional issues were more likely to be discussed and acknowledged by the GP where there was a long-standing relationship between GP and patient. CONCLUSION: Pre-existing positive GP-patient relationships and supportive communication enable people with 2TD to raise emotional issues as part of diabetes care.

ItemThe development of Future Health Today: piloting a new platform for identification and management of chronic disease in general practice(CSIRO Publishing, 2022)Chronic disease identification and management is a significant issue in Australia, with general practice being the primary contact point for those at risk of, or living with, chronic disease. However, there is a well-described gap between guideline recommendations for chronic disease management and translation in the general practice setting. In 2018, a group of researchers, clinicians and software developers collaborated to develop a tool to support the identification and management of chronic disease in general practice, with the aim to create a platform that met the needs of general practice. The co-design process drew together core principles and expectations for the establishment of a technological platform, called Future Health Today (FHT), which would sit alongside the electronic medical record (EMR) management system within general practice. FHT used algorithms applied to EMR data to identify patients with, or at risk of, chronic disease and requiring review. Using chronic kidney disease as a clinical focus, the FHT prototype was piloted in a large, metropolitan general practice, and a large regional general practice. Based on user feedback, the prototype was further developed and improved. This paper provides a report on the key features and functionalities that participants identified and implemented in practice.
