Exploring recent trends (2014–21) in preferencing and accepting Queensland medical internships in rural hospitals

BackgroundMedical internship is a key transition point in medical training from student to independent (junior) doctor. The national Regional Training Hubs (RTH) policy began across Australia in late 2017, which aims to build medical training pathways for junior doctors within a rural region and guide students, interns and trainees towards these. This study aims to explore preferencing and acceptance trends for rural medical internship positions in Queensland. Moreover, it focuses on internship preference and acceptance outcomes prior to and following the establishment of RTHs, and their association with key covariates such as rural training immersions offered by medical schools.MethodsData from all applicants to Queensland Health intern positions between 2014–2021 were available, notably their preference order and location of accepted internship position, classified as rural or metropolitan. Matched data from Queensland’s medical schools were added for rural training time and other key demographics. Analyses explored the statistical associations between these factors and preferencing or accepting rural internships, comparing pre-RTH and post-RTH cohorts.ResultsDomestic Queensland-trained graduates first preferencing rural intern positions increased significantly (pre-RTH 21.1% vs post-RTH 24.0%, p = 0.017), reinforced by a non-significant increase in rural acceptances (27.3% vs 29.7%, p = 0.070). Rural interns were more likely to have previously spent ≥ 11-weeks training in rural locations within medical school, be rurally based in the year applying for internship, or enrolled in the rural generalist pathway.ConclusionsThe introduction of the RTH was associated with a moderate increase of graduates both preferencing and accepting a rural internship, though a richer understanding of the dominant reasons for and against this remain less clear. An expansion of graduates who undertook longer periods of undergraduate rural training in the same period did not diminish the proportion choosing a rural internship, suggesting there remains an appetite for these opportunities. Overall, domestic graduates are identified as a reliable source of intern recruitment and retention to rural hospitals across Queensland, with entry to the rural generalist pathway and extended rural placement experiences enhancing uptake of rural practice.

Child health nurses' perceptions of the Family Community-based Assistance Resourcing and Education program in contemporary practice: a qualitative study.

The Family Community-based Assistance Resourcing and Education Program (FCP) is a nurse home visiting program that was introduced in Queensland two decades ago to redress health inequalities for infants from families experiencing specific social stressors. Locally adapted versions of this home visiting program are still in use, but have not been evaluated. This study examined child health nurse perceptions of the adapted FCP in one regional Queensland health service. A qualitative descriptive exploratory study using two focus groups (conducted May 2019) with Child Health Nurses who delivered the FCP was conducted. Transcripts of digital recordings were analysed using Braun and Clarke's (2006) six-step framework for guided thematic analysis. A total of 16 Child Health Nurses participated in the study, with a mean of 10years' experience with the program. Data analysis generated 12 themes organised under three domains: 'Establishing the relationship with families', 'What works in practice' and 'We could do it better'. Participants cited flexibility, expert input and in-home delivery as key program benefits. However, narrow eligibility criteria, poor screening for perinatal anxiety and resourcing constraints were identified as limitations. This study is the first to measure Child Health Nurses' perceptions of an adapted FCP. It sheds light on their 'practice wisdom', including the program's ability to meet the needs of families with social vulnerabilities. The study supports prior calls for home visiting programs to be evaluated against clearly stated program intentions. Participant insights have been shared to inform practice and program implementation both locally and as part of Queensland's First 2000Days health service delivery reform agenda.

Participant characteristics and reasons for non-consent to health information linkage for research: experiences from the ATHENA COVID-19 study

BackgroundThe linkage of primary care, hospital and other health registry data is a global goal, and a consent-based approach is often used. Understanding the attitudes of why participants take part is important, yet little is known about reasons for non-participation. The ATHENA COVID-19 feasibility study investigated: 1) health outcomes of people diagnosed with COVID-19 in Queensland, Australia through primary care health data linkage using consent, and 2) created a cohort of patients willing to be re-contacted in future to participate in clinical trials. This report describes the characteristics of participants declining to participate and reasons for non-consent.MethodsPatients diagnosed with COVID-19 from January 1st, 2020, to December 31st, 2020, were invited to consent to having their primary healthcare data extracted from their GP into a Queensland Health database and linked to other data sets for ethically approved research. Patients were also asked to consent to future recontact for participation in clinical trials. Outcome measures were proportions of patients consenting to data extraction, permission to recontact, and reason for consent decline.ResultsNine hundred and ninety-five participants were approached and 842(85%) reached a consent decision. 581(69%), 615(73%) and 629(75%) consented to data extraction, recontact, or both, respectively. Mean (range) age of consenters and non-consenters were 50.6(22-77) and 46.1(22-77) years, respectively. Adjusting for age, gender and remoteness, older participants were more likely to consent than younger (aOR 1.02, 95%CI 1.01 to 1.03). The least socio-economically disadvantaged were more likely to consent than the most disadvantaged (aOR 2.20, 95% 1.33 to 3.64). There was no difference in consent proportions regarding gender or living in more remote regions. The main reasons for non-consent were ‘not interested in research’ (37%), ‘concerns about privacy’ (15%), ‘not registered with a GP’ (8%) and ‘too busy/no time’ (7%). ‘No reason’ was given in 20%.ConclusionYounger participants and the more socio-economically deprived are more likely to non-consent to primary care data linkage. Lack of patient interest in research, time required to participate and privacy concerns, were the most common reasons cited for non-consent. Future health care data linkage studies addressing these issues may prove helpful.

Exploring equity of care for Aboriginal and Torres Strait Islander peoples within the state-wide Musculoskeletal Physiotherapy Screening Clinic and Multi-disciplinary Service in Queensland Health.

ObjectiveThis study aimed to explore equity of care for Aboriginal and Torres Strait Islander peoples compared to non-Indigenous Australians within a Queensland-wide musculoskeletal service.MethodThe service database was analysed between July 2018 and April 2022 across 18 Queensland Health facilities. Representation of Aboriginal and Torres Strait Islander peoples within the service's patient population was first explored. Second, service and patient-related characteristics and outcomes between Aboriginal and Torres Strait Islander patients and non-Indigenous patients undergoing an episode of care in the service were compared using analysis of variance and chi-squared tests.ResultsA greater proportion of Aboriginal and Torres Strait Islander peoples (4.34%) were represented within the service's patient population than in the general population (3.61%) state-wide. Aboriginal and Torres Strait Islander patients presented with a generally higher severity of clinical presentation across measures at initial consult. Very similar proportions of Aboriginal and Torres Strait Islander (63.2%) and non-Indigenous (64.3%) patients reported clinically meaningful treatment benefits. While a higher proportion of Aboriginal and Torres Strait Islander patients (69.7%) were discharged from the service without requiring specialist review compared to non-Indigenous patients (65.6%), Aboriginal and Torres Strait Islander patients had higher rates of discharge due to non-attendance (20.8%) when compared to non-Indigenous (10.6%) patients (P<0.01).ConclusionsDisparity in care retention for Aboriginal and Torres Strait Islander patients compared to non-Indigenous patients was observed within the musculoskeletal service. Consultation with Aboriginal and Torres Strait Islander communities is needed to address access barriers once in the service to guide service improvement.

Driving value-based healthcare through a new vision for Queensland's health system.

The purpose of this case study is to explain the development of Queensland's strategic approach to health system reform, which promotes partnership across the health system to better deliver integrated and value-based health care across the continuum of care. The new health system vision was informed by undertaking literature searches on national and international health system approaches to reform and supported by extensive consultation across Queensland with more than 1100 stakeholders. Thematic analysis was undertaken to identify key themes that were translated into a high-level vision document that communicated Queensland's renewed focus on wellness and delivering more care in the community. This was circulated to stakeholders for iterative and collaborative refinement before final approvals. Collaboratively and iteratively developing the new health system vision for Queensland with key stakeholders has contributed to a shared understanding and ownership of a vision that is committed to system reform, focused on delivering high-value care that reflects what is important to consumers and health system stakeholders.

Building knowledge and capacity for climate change risk management in the health sector: The case of Queensland

In 2019, the Queensland Department of Health and National Climate Change Adaptation Research Facility at Griffith University co-produced three resources to support Queensland Hospital and Health Service (HHS) staff to identify and manage present-day and future risks from climate change. The first resource is two templates to be completed in order to develop a risk management plan: the high-level Scan Cycle template, and the Detailed Cycle template for evaluation of serious risks requiring urgent action. Second, the Guidelines lead the user through the process. Third, an Almanac provides supporting information and links to additional resources. Together, these resources deliver a comprehensive set of tools, known as the ‘Guidance’, to support and guide HHS staff to address their climate change risks. A programme of training workshops was carried out throughout Queensland, taking staff from all HHS sectors through the templates and providing opportunity for in-depth discussion of their risks. Some gaps in the Guidance were identified in the workshops, for example the need to include humidity in the climate scenarios for Queensland’s subtropical and tropical environments, and to consider system-wide interdependencies when identifying effective adaptation strategies for the highly complex HHSs. Some barriers to effective utilisation of the Guidance include, for example its complexity balanced against the time available to staff. The Guidance is an effective tool to promote and guide adaptation action, but in itself is insufficient – it requires senior management support and financing, and possibly regulatory reporting requirements, in order to properly fulfil its role.

Creating a framework for change: transitioning to value-based healthcare in Queensland.

Value-based healthcare has been described as the sustainable, equitable and transparent use of healthcare resources to achieve improved experiences and outcomes for people and communities. It is supported by all levels of government in Australia, with recent initiatives championing a shift away from traditional, clinician-centric care delivery to a more contemporary, value-based approach. To date, however, efforts in Queensland have focused on smaller scale siloed models of care and have not extended to the transformational change required to create equitable and sustainable healthcare delivery. The Queensland Health Allied Health Framework for Value-Based Health Care (the Framework) builds on contemporary frameworks with reference to the local context in Queensland and provides a structure and starting point for clinicians and managers to work together with consumers to transform services to focus on preventative health and wellbeing, shifting the focus of care to the community and sustainably improving the quality of care delivered. The Framework outlines key considerations for the design and implementation of new services, including understanding the care pathway, supporting an outcome driven workplace culture, measuring what matters and designing for outcomes. Several key lessons were learnt during the development of the Framework, including the importance of early and sustained consumer partnerships, of establishing a shared definition of value-based healthcare that enables integration across the care pathway and the need for leadership at all levels to actively support the change management process. While developed for Queensland public allied health services, the Framework is intended to be a system-wide tool relevant to all health professionals and services.

The role of law in end-of-life decision-making in emergency departments and intensive care units: a retrospective review of current practice in a Queensland health service.

Objective There is limited evidence about how legal frameworks that underpin end-of-life decisions are applied in practice. This study aimed to identify how end-of-life decisions are made and documented in emergency departments and intensive care units. The secondary aim was to explore the extent to which the legal processes featured in these decisions. Methods A retrospective chart audit of 85 adult patients who died in the emergency departments and intensive care units of a Queensland health service was undertaken. Quantitative data were analysed and reported using descriptive statistics. Qualitative textual data were analysed using inductive content analysis. Results Nearly all admissions were unplanned (97.6%), and most patients (74.1%) were admitted from home. Only one patient had an advance health directive, although all had an eligible substitute decision-maker. The qualitative analysis revealed two main concepts - 'healthcare professionals choreograph the end of life' and 'patients and families are carried on an unplanned journey'. Conclusions There was limited documentation related to the application of the legal framework in these decisions. Healthcare professionals relied on their clinical judgment about what was in the best interest of the patient. It was common for there to be a substantial effort to achieve consensus in decision-making which coincidently complied with the law.

Tunneled Hemodialysis Catheter Tip Design and Risk of Catheter Dysfunction: An Australian Nationwide Cohort Study

Rationale & ObjectiveHemodialysis catheter dysfunction is an important problem for patients with kidney failure. The optimal design of the tunneled catheter tip is unknown. This study evaluated the association of catheter tip design with the duration of catheter function. Study DesignObservational cohort study using data from the nationwide REDUCCTION trial. Setting& Participants: 4722 adults who each received hemodialysis via one or more tunneled central venous catheters in 37 Australian nephrology services from December 2016 to March 2020. ExposureDesign of tunneled hemodialysis catheter tip, classified as symmetrical, step, or split. OutcomeTime to catheter dysfunction requiring removal due to inadequate dialysis blood flow assessed by the treating clinician. Analytical ApproachMixed, three-level accelerated failure time model, assuming a log-normal survival distribution. Secular trends, the intervention, and baseline differences in service, patient, and catheter factors were included in the adjusted model. In a sensitivity analysis, survival times and proportional hazards were compared among participants’ first tunneled catheters. Results355 of 3871 (9.2%), 262 of 1888 (13.9%), and 38 of 455 (8.4%) tunneled catheters with symmetrical, step, and split tip designs, respectively, required removal due to dysfunction. Step tip catheters required removal for dysfunction at a rate 52% faster than symmetrical (adjusted time ratio = 0.48, 95% CI = 0.34-0.69), and 76% faster than split tip catheters (adjusted time ratio = 0.24, 95% CI = 0.11-0.52) in the adjusted accelerated failure time models. Only symmetrical tip catheters had performance superior to step tip catheters in unadjusted and sensitivity analyses. Split tip catheters were infrequently used and had risks of dysfunction similar to symmetrical tip catheters. The cumulative incidence of other complications requiring catheter removal, routine removal, and death prior to removal were similar across the three tip designs. LimitationsTip design was not randomized. ConclusionsSymmetrical and split tip catheters had a lower risk of catheter dysfunction requiring removal than step tip catheters.Funding: Grants from government (Queensland Health, Safer Care Victoria, Medical Research Future Fund, National Health and Medical Research Council, Australia), academic (Monash University), and not-for-profit (ANZDATA Registry, Kidney Health Australia) sources.

Artificial intelligence in medical referrals triage based on Clinical Prioritization Criteria

The clinical prioritisation criteria (CPC) are a clinical decision support tool that ensures patients referred for public specialist outpatient services to Queensland Health are assessed according to their clinical urgency. Medical referrals are manually triaged and prioritised into three categories by the associated health service before appointments are booked. We have developed a method using artificial intelligence to automate the process of categorizing medical referrals based on clinical prioritization criteria (CPC) guidelines. Using machine learning techniques, we have created a tool that can assist clinicians in sorting through the substantial number of referrals they receive each year, leading to more efficient use of clinical specialists' time and improved access to healthcare for patients. Our research included analyzing 17,378 ENT referrals from two hospitals in Queensland between 2019 and 2022. Our results show a level of agreement between referral categories and generated predictions of 53.8%.

No Dramas: Using applied theatre to explore youth health issues in regional Central Queensland.

Young people in a regional Central Queensland community identified concerns related to their health and health behaviours, but have limited access to health information. To explore the youth health perspectives and priorities of young people in regional Queensland and identify how young people prefer to access health information. A participatory action research approach, using applied theatre methods and technology. The key challenges to youth health in regional Queensland identified by participants were substance use, in particular vaping, and bullying. Short-form social media videos are an effective channel for communicating youth health information, but to do so must closely align with the predominant formats and trends on social media platforms. Young people are not likely to read health information in printed form. Effective communication is the key to empowering young people to make decisions regarding their health behaviours. Our research shows that young people tend to share with other young people, and they are less likely to listen to older people and those in positions of authority. Health concerns raised ranged from cyberbullying and peer pressure to vaping, alcohol and chroming. Young people are more likely to engage with information that reflects their lived experience. The research concludes that we need to reconsider how information is provided for young people. Ways to empower young people and their voices via their preferred genre and format, not only to inform their health behaviours but also other aspects of their lives, is imperative.

Several confirmed and probable zoonotic cases of toxigenic Corynebacterium ulcerans, Queensland, Australia.

Toxigenic Corynebacterium ulcerans is an emerging zoonosis globally, causing both cutaneous and respiratory diphtheria-like illness. In Queensland, human infection with toxigenic C. ulcerans is rare, with only three cases reported before October 2015. This case series describes five subsequent cases of toxigenic C. ulcerans in Queensland with links to companion animals. All data were collected as part of routine public health response, and strains were whole genome sequenced for further characterisation. Household contacts were screened, treated with appropriate antibiotics, and received a diphtheria toxoid-containing vaccine if more than five years had elapsed since their last dose. No epidemiological or genomic links could be established between any of the five patients, including between the two cases notified from the same locality within eight days of each other. The C. ulcerans strains from Cases Two, Four and Five were closely related to the strains isolated from their respective pets by whole genome sequencing. Domestic dogs were identified as the most likely mode of transmission for Cases One and Three; however, this was unable to be laboratory confirmed, since Case One's dog was treated with antibiotics before it could be tested, and Case Three's dog was euthanised and cremated prior to case notification. These are the first reported Australian cases of this emerging zoonosis with links to companion animals. These cases demonstrate the likely transmission route between companion animals and humans, with no evidence of human-to-human transmission. The existing requirement in the Queensland Health Public Health Management Guidelines, of restrictions on cases and some contacts while awaiting swab results, is currently under review.

High-risk antenatal women's perceptions of dietitian appointments and information

ProblemThe dietitian service at a metropolitan health service in Queensland, Australia has a non-engagement rate for high-risk antenatal women of 50%. AimDetermine which attributes are related to non-attendance at dietitian appointments, and women's perceptions and attitudes towards dietitian appointments during pregnancy. MethodsAn explanatory mixed-methods design was utilised, with first phase including 103 antenatal women referred to a dietitian in 2021 and compared the attributes of those who attended with those who did not engage. Queensland Health electronic databases were used to collect attribute data, which were then analysed with Jamovi (version 1.6) for descriptive, correlational, multivariate analyses of variance MANOVA. Second phase included seven semi-structured interviews with women attending a dietitian appointment, and subsequently analysed through thematic analysis. ResultsDistance from clinic was not related to clinic attendance, and women reported they would attend regardless of distance or work status. Non-attendance was related to higher gravidity, parity, and if referred for obesity, but not previous gastric sleeve or underweight referral. Six themes were identified from the interview data: “Women want to be treated like an individual,” “It's all about expectations,” “Midwives hold the key,” “Preferences in receiving dietary information,” “Weight has been a long-term problem and is a sensitive topic,” and “Barriers to attendance.” ConclusionAntenatal services can adjust service delivery to improve engagement in weight management services during pregnancy. Telehealth appointments may reduce non-engagement due to distance from clinic. Demystifying the dietitian appointment, ensuring non-judgemental referral processes and collaboration between midwives and dietitians will ensure that women value the service.

Airborne grass pollen and thunderstorms influence emergency department asthma presentations in a subtropical climate

BackgroundGrass pollen is considered a major outdoor aeroallergen source worldwide. It is proposed as a mechanism for thunderstorm asthma that lightning during thunderstorms promotes electrical rupture of pollen grains that leads to allergic airway inflammation. However, most evidence of associations between grass pollen and asthma comes from temperate regions. The objective of this study was to investigate short-term associations between airborne grass pollen exposure and asthma emergency department presentations in a subtropical population. MethodsEpisode level public hospital presentations for asthma (2016–2020) were extracted for greater Brisbane, Australia, from Queensland Health's Emergency Data Collection. Concentrations of airborne pollen were determined prospectively using a continuous flow volumetric impaction sampler. Daily time series analysis using a generalised additive mixed model were applied to determine associations between airborne grass pollen concentrations, and lightning count data, with asthma presentations. ResultsAirborne grass pollen showed an association with asthma presentations in Brisbane; a significant association was detected from same day exposure to three days lag. Grass pollen exposure increased daily asthma presentations up to 48.5% (95% CI: 12%, 85.9%) in female children. Lightning did not modify the effect of grass pollen on asthma presentations, however a positive association was detected between cloud-to-cloud lightning strikes and asthma presentations (P = 0.048). ConclusionAirborne grass pollen exposure may exacerbate symptoms of asthma requiring urgent medical care of children and adults in a subtropical climate. This knowledge indicates an opportunity for targeted management of respiratory allergic disease to reduce patient and health system burden. For the first time, an influence of lightning on asthma was detected in this context. The outcomes support a need for continued pollen monitoring and surveillance of thunderstorm asthma risk in subtropical regions.

The Overlaps between Intergenerational (Dis)Continuity of Child Protection Services Involvement and Mental Illness Diagnoses from Hospital Admissions

Abstract Purpose This study examines the relationship between mental illness diagnoses and four intergenerational patterns of child protection services involvement: cycle breakers, cycle maintainers, cycle initiators, and a comparison group (no maltreatment). Existing research is limited and inconsistent, and rarely incorporates multiple categories of mental illness or considers variation between mental illnesses. Methods Data were drawn from an administrative population-based data repository in Queensland, Australia and includes 32,494 individuals identified as biological parents. Child protection data were obtained from the Department of Children, Youth Justice and Multicultural Affairs and mental illness diagnoses were obtained from Queensland Health hospital admissions. Any mental illness diagnosis, age at onset (adolescence or adulthood), and diagnosis types (common, severe, personality disorders, childhood-onset, adolescent- and adult-onset, and substance use) were examined. Multinomial and logistic regressions were conducted to investigate whether the mental illness diagnosis variables distinguished the four intergenerational patterns of child protection service involvement. Results Overall, 10.4% of individuals had at least one hospital admission involving a mental illness diagnosis. The prevalence of mental illness diagnoses significantly differed across the intergenerational patterns. Cycle maintainers and cycle initiators received the highest rates of diagnoses (50% and 38.8%, respectively), compared to cycle breakers (21.1%) and the comparison group (7.7%). Conclusions Our findings underline the need for early access to mental health supports for families involved with the child protection system, which could help prevent the cycle of maltreatment.

Molecular epidemiology of hepatitis B among Indigenous Australians in Queensland and the Torres Strait Islands.

Chronic hepatitis B virus (HBV) infection is a major health problem for all Indigenous Australians. Post-2000, Hepatitis B surface antigen prevalence has decreased, although remaining four times higher among Indigenous compared with non-Indigenous people. This study aimed to characterise the HBV from Indigenous populations in Queensland and the Torres Strait Islands. Serum samples were collected, with consent, from people within Queensland Indigenous communities prior to 1990 as part of the Queensland Health vaccination programme. Ethics approval was subsequently obtained to further characterise the HBV from 93 of these stored samples. HBV DNA was extracted and genotype was obtained from 82 samples. HBV full genome sequencing was carried out for a subset of 14 samples. Seventy-eight samples were identified as genotype C (2 × C12, 3 × C13 and 73 × C14), one sample as genotype A (A2) and three samples as genotype D (1 × D2, 1 × D3 and 1 × D4). The HBV/C sequences identified were most closely related to sequences isolated from Papua New Guinea and Indonesia (Papua Province). The HBV isolated from the Torres Strait Islanders was notably different to the HBV/C4 strain isolated from Indigenous people of mainland northern Australia, with no evidence of recombination. This reflects the differences in culture and origin between Torres Strait Islanders and mainland Indigenous people.
