Genomic Newborn Screening: Verdict From an Australian Citizens’ Jury

Objective To support a nationally representative group of Australians to make informed, reasoned recommendations on the use of genomics in newborn screening programmes. Design Hybrid Citizens’ Jury method. Setting, Participants Thirty Australian adults recruited by random ballot invitation and stratified selection against population-based demographic targets of age, sex, ancestry, highest level of education, location of residence (state/territory, urban/non-urban), experience of disability and parent/non-parent. Main Outcome Measures Jury recommendations with reasons. Results The jury made 11 recommendations. The jury agreed whole genome sequencing could be used in the programme, but only if conditions were met regarding national consistency, benefit, Australian Government oversight, consent, reporting to parents, data protection, supporting parents and the healthcare system, and parent and public education. All of these conditions were agreed by consensus, except reporting to parents and parent and public education, where there was a supermajority (24/30) in agreement and minority dissent. The jury were split on Recommendation 11: how much genomic data should be extracted and retained. Nine jurors supported whole genome sequencing only if data extraction and retention were limited to interpretable, actionable genetic information; 21 jurors supported a more expansive approach. Conclusions To maintain public trust in Australian newborn screening, programmes should take a more conservative approach to data extraction and storage until concerns are addressed and safeguarding conditions implemented. Jurors' key concerns include identifiability of genomic data, risk of data misuse and potential to undermine trust and participation in newborn screening.

Uptake and Costs of the 60-Day Dispensing Policy for Antihypertensive Medicines in Australia: A Mixed Methods Study

Objectives To evaluate the uptake of a new 60-day dispensing policy for antihypertensive medicines and estimated cost savings compared with conventional 30-day dispensing; and to explore general practitioner and pharmacist perspectives on the new policy. Study Design Mixed methods design; analysis of Pharmaceutical Benefits Scheme (PBS) dispensing claims from 1 September 2023 to 30 April 2025; and semi-structured interviews with 20 general practitioners and four pharmacists from 13 June 2024 to 24 September 2024 to gauge their perspectives on 60-day dispensing. Setting, Participants General practitioners and pharmacists practising in New South Wales, Victoria and Queensland, Australia. Main Outcome Measure Antihypertensive prescription volumes; patient and government cost savings; and perceptions of the policy from general practitioners and pharmacists. Results The 60-day antihypertensive prescription volume increased from 75,500 to 877,700 over 20months, accounting for 21.2% of all antihypertensive dispensing by 30 April 2025. We estimate the total cost savings for patients were up to ~$65 million, and the government saved ~$87 million and paid pharmacies ~$86.7 million via the Additional Community Supply Support (ACSS) payment program, with a net effect of ~$0.3 million. In interviews, general practitioners indicated varied utilisation of 60-day prescriptions, with some actively providing 60-day prescriptions, but some rarely or not at all. Barriers included keeping abreast of eligible and ineligible medicines for 60-day prescriptions and perceived resistance from pharmacists. Pharmacists were concerned about incorrect dispensing and potential medication shortages. Conclusion At 20months after the introduction of the new policy, 21.2% of antihypertensive prescriptions were for 60-day dispensing. The slow uptake is likely due to low uptake among general practitioners and resistance from pharmacists. The 60-day policy has demonstrated substantial financial savings for patients. If uptake of 60-day dispensing increased to 50%, annual savings from antihypertensive medicines could rise to up to ~$165 million for patients and ~$11.6 million for the government.

Motor Neuron Disease Mortality Trends in Australia From 1986 to 2023: A Population-Based Study

Objectives To analyse longitudinal change in motor neuron disease (MND) mortality in Australia from 1986 to 2023. Design Australian population-based study of MND mortality. Setting All MND mortality and Australian population data from 1 January 1986 to 31 December 2023 were obtained from the Australian Bureau of Statistics. Main Outcome Measures MND mortality records were analysed, and certified deaths were summarised by year of registration. MND mortality rates, 95% confidence intervals (CIs) and Joinpoint regression trends were calculated. Data were further subset by demographic and geographical categories to report Australian MND mortality by age group, sex, state/territory location and remoteness areas classification. Results In Australia, the total number of MND deaths more than tripled over the past 37years, from 238 in 1986 to 781 in 2023. The unadjusted mortality rate in 1986 was 1.49 (95% CI, 1.30–1.69) per 100,000 population and increased to 2.93 (95% CI, 2.73–3.14) per 100,000 population by 2023. After age standardisation, the annual percentage change across 1986–2023 was determined to be 0.47% (95% confidence limit, 0.16–0.86). Joinpoint modelling suggests a more recent reduction in adjusted mortality rates. In 2023, MND accounted for 0.43% of all-cause deaths in Australia, increasing from 0.21% in 1986. The number of MND deaths in Australia peaked at age 70–79years. MND mortality was higher among men than women (rate ratio, 1.41; 95% CI, 1.33–1.51). MND mortality rates were similar among New South Wales, Victoria and Queensland (2.93, 3.08 and 2.85 per 100,000 population, respectively), with higher rates in South Australia and Tasmania (3.44 and 4.12 per 100,000 population, respectively). MND mortality rates were higher in inner and outer regional areas (3.90 and 3.24 per 100,000 population, respectively) compared with major cities (2.79 per 100,000 population). Conclusions Adjusted MND mortality rates in Australia increased over 37years.

Emergency Department Presentations and Hospitalisations for Elder Abuse in People Accessing Aged Care Services in Australia: A Retrospective Cross-Sectional Study

Elder abuse can lead to serious physical injuries and long-term psychological consequences, but its recognition and documentation in healthcare settings remain limited. This study used linked data from four Australian states to examine elder abuse coded during emergency department presentations and hospitalisations among 965,986 older people assessed for aged care services between 2010 and 2019. Only 580 people (0.06%) had elder abuse coded during an emergency department presentation or hospitalisation, highlighting substantial under-recognition and under-reporting in hospital settings.

The Association Between Alignment to the Breast Cancer Optimal Care Pathways and Patient Survival in Victoria, Australia, 2012–2019: A Retrospective Population-Based Cohort Study

Objectives To quantify the association between care alignment to the treatment step of the Cancer Council Victoria and Department of Health Victoria Optimal care pathways for people with breast cancer (OCP) (second edition) and survival. Design Retrospective population-based cohort study using the Victorian Cancer Registry and linked administrative health datasets. Setting, Participants Adult women diagnosed with invasive, unilateral breast cancer from 1 July 2012 to 31 December 2019 in Victoria, Australia. Main Outcome Measures Breast cancer-specific and overall survival for women whose care did or did not align to the treatment step of the OCP expressed as adjusted hazard ratios. Interaction between OCP alignment and cancer stage at diagnosis was also assessed. Results Of 29,591 eligible women, 17,152 (58.0%) were fully aligned, 7086 (23.9%) were partially aligned and 5353 (18.1%) were not aligned to the treatment step of the breast cancer OCP. Median follow-up was 1481days (interquartile range, 850–2210days). Adjusting for measured sociodemographic and clinical factors, OCP treatment alignment was associated with 23% (95% confidence interval [CI], 14%–31%) and 34% (95% CI, 29%–40%) lower risk of death from breast cancer and all causes, respectively, compared with non-alignment. By cancer stage, OCP alignment was significantly associated with 40% (95% CI, 27%–50%) and 30% (95% CI, 14%–42%) lower risk of breast cancer death for Stage II and III cancers, respectively, and 39% (95% CI, 26%–49%), 49% (95% CI, 42%–55%) and 33% (21%–44%) lower risk of all-cause death for Stage I, II and III cancers, respectively. Conclusions Risk of death was lower for women with breast cancer whose treatment aligned to the OCP compared with women whose treatment did not align. Our findings support the promotion and implementation of the breast cancer OCP.

Malignant Otitis Externa in Central Australia: A 15-Year Retrospective Review Between 2009 and 2024

We performed a 15-year retrospective audit of all cases of malignant otitis externa (MOE) referred to Alice Springs Hospital in Central Australia from 2009 to 2024, the largest Australian series of MOE. Data on demographics, risk factors, microbiological culture results, management and outcomes were collected, identifying 64 cases of MOE, with the incidence increasing over time. The incidence of MOE was associated with Indigenous status and the presence of diabetes mellitus and chronic kidney disease. Pseudomonas, Staphylococcus aureus and fungal pathogens predominate as causal agents. Complications and mortality were common.

Ngalaiya Boorai Gabara Budbut: A Qualitative Study With Primary Care Providers to Understand Perceived Needs, Enablers, Barriers and Opportunities to Strengthen Care

Objective To explore primary care providers' perspectives on (i) healthcare needs and barriers to care for Aboriginal and Torres Strait Islander children and adolescents; and (ii) enablers and opportunities to strengthen care. Study Design A qualitative study; interviews and open-ended survey responses. Setting Primary care providers who work with Aboriginal and Torres Strait Islander children and young people in health and education settings in New South Wales and the Australian Capital Territory. Data were collected between 23 March 2022 and 13 October 2023. Main Outcome Measures Sixteen interviews and 33 open-ended survey responses were analysed using reflexive thematic analysis with a hybrid inductive/deductive approach. Results Participants reported that some of the most important health needs for children and young people related to mental health. They recognised that the presenting complaint was not always the underlying or only concern, demonstrated an understanding of trauma-informed care and acknowledged the importance of collaborative services that engaged support networks. Barriers to care included a lack of cultural safety in mainstream services, challenging social circumstances, financial concerns, being unaware of available services and privacy and confidentiality concerns. To improve care, staff identified several areas needing change including having a package of services tailored for young people; additional training for providers in child and adolescent health, particularly for mental healthcare, trauma-informed care and communication with young people; providing a safe and engaging environment; support for staff self-care; and additional resources. Conclusions Supporting mental health needs is a key aspect of caring for children and adolescents. To provide optimal primary healthcare, service providers require specialist skills. To support adolescents and children, participants identified a need for ongoing training, professional development and organisational support to ensure best practice care is sustained. This work has informed the development of training and other resources for partner health services.

Strategies for Reducing Access Block and Waiting Time for Patients Seeking Emergency Hospital Care: Results of a Ward-Level Discrete Event Simulation at Queensland's Largest Public Hospitals

Objective To assess the impact of strategies to improve public hospital emergency access using a detailed ward-level simulation modelling approach. Design and Setting Discrete event simulation was used to simulate patient flow at three principal referral Australian hospitals from 1 September 2021 to 31 August 2022. Models were developed and validated using every emergency department (ED) presentation, inpatient episode of care and patient ward movement at the study hospitals. Main Outcome Measures Mean and total ED length of stay, mean waiting time, access block rate, 4-h rule compliance and bed utilisation for patients admitted from the ED. Results Reducing ED demand via arrangements that accommodate the same proportion and types of admissions from the ED as the existing ED presenting population reduces access block, with larger impacts in winter than in summer. However, reducing ‘general practitioner-type patients’ in EDs has negligible impact on access block. Tangible impacts on improving patient flow can be achieved by removing maintenance care patients from hospitals (reducing the percentage of access block by up to a third) and reducing elective admissions. Strategies that emphasised morning, midday and early afternoon discharges led to large flow improvements. The strategy already practised by most hospitals of sharing patients among wards greatly improves emergency access, and gains are the same order of magnitude as reducing overall ED demand. Conclusions The study provides support to policymakers looking for evidence regarding strategies to improve emergency access to public hospital care.

The Impact of Hospital Bed Occupancy on Patient Flow and Emergency Department Access: A 25-Hospital Cohort Study

Objectives To evaluate the effect of hospital occupancy levels on inpatient and emergency department (ED) flow rates, ED length of stay (ED) and access block, and identify critical occupancy thresholds above which patient flow deteriorates. Design Retrospective cohort study using routinely collected administrative data. Setting Twenty-five public hospitals in Queensland, Australia, over a 5.5-year period (1 April 2017 to 31 August 2022). Main Outcome Measures ED presentation and discharge rates, inpatient admission and discharge rates, hospital occupancy levels, length of stay, access block and 4-h rule compliance. Results The analysis reveals a significant performance shift as hospital occupancy levels increase and identifies site-specific critical ‘choke points’ where patient flow deteriorates. Notably, as occupancy rises, we observed a growing divergence between ED presentations and discharge rates, and between inpatient admissions and discharges, indicating system congestion. Additionally, when assessing flow across the 25 hospitals, the data demonstrates that a 10% increase in bed occupancy rate correlates with a 0.32-h (19-min) extension in ED length of stay (or 33min for patients admitted from the ED). Also, significant disparities in hospital operations were observed between weekends and weekdays, with weekday admissions and discharges up to three times higher than weekends, highlighting the increased operational pressure during the work week. Conclusions The investigation challenges the traditional 85% occupancy target, demonstrating that optimal occupancy levels vary by hospital. The study also underscores the strong correlation between hospital bed occupancy and ED access performance, with higher hospital occupancy correlating with longer ED stays and decreased adherence to performance indicators. As hospitals approach full capacity, the pressure on ED resources intensifies, resulting in longer wait times and delays in care.

Spatial and Temporal Patterns in Childhood and Adolescent Asthma Hospitalisations in Queensland, Australia: A 20-Year Ecological Study Across Climate Zones

Objectives To examine spatial, temporal and seasonal patterns in childhood and adolescent asthma hospitalisations across Queensland, and assess variation in hospitalisation risk by age and sex across climate regions. Design A retrospective, population-based ecological study using area-level administrative data from hospital admissions. Setting All public and private hospitals in Queensland, Australia, 1 January 2000–31 December 2019. Participants Children and adolescents aged 0–19years who were admitted to hospital with a principal diagnosis of asthma. Main Outcome Measures Age-standardised admission rates and relative risks (RRs) from spatial models; temporal patterns from time-series analysis; spatial variation from mapping; age-, sex- and climate zone-specific risks. Results Hospitalisations among children aged 0–4years declined from 48.1% (1640 admissions) in 2000 to 23.2% (721 admissions) in 2019, whereas proportions in older age groups increased. Seasonal peaks occurred in May, June and February, with male patients showing a stronger February peak and female patients maintaining higher risks into July. Hot desert regions had the highest RRs, rising from 3.73 (95% credible interval [CrI], 3.71–3.74) in 2000–2001 to 9.37 (95% CrI, 9.28–9.47) in 2009–2010, then declining to 2.37 (95% CrI, 2.37–2.38) in 2018–2019. Hot semi-arid and tropical savanna regions showed persistently elevated risks (hot semi-arid: RR, 1.86–3.75; tropical savanna: RR, 1.81–4.58). Three temporal phases were evident statewide: an early lower-risk period (2000–2002), a higher-risk period (2002–2012) and a later reduction (2012–2019), with most RRs between 0.5 and 1.5. Seasonality was strongest in hot desert zones (seasonal strength, 0.519) and weakest in tropical savanna zones (0.063). Conclusions Childhood and adolescent asthma hospitalisations in Queensland exhibit significant spatiotemporal variation, with burden shifting from younger to older children, and climate-specific risks, although observed reductions in the youngest age group may partly reflect diagnostic and hospital admission practice changes. Higher asthma risks in arid and tropical savanna regions underscore the need for geographically tailored services and planning. These findings suggest that targeted public health strategies might help reduce asthma burden in vulnerable communities.

The Association Between Access Block And Ambulance Ramping, And The Impact of COVID-19: A Retrospective Observational Cohort Study of 25 Queensland Hospitals

ObjectiveTo explore the characteristics of ambulance ramping and its association with access block before, during and after the first wave of the coronavirus disease 2019 (COVID-19) pandemic.DesignRetrospective observational study.SettingExploratory data analysis and statistical modelling covering the ambulance–emergency department (ED) interface of the 25 largest public hospitals in Queensland between 1 January 2018 and 31 December 2022.Main Outcome MeasuresPrimary outcome: The association between ramping, assessed as the ambulance performance target patient off-stretcher time (POST) and access block, and how COVID-19 affected these time-sensitive processes. Secondary outcomes: The association between POST and ambulance response time and between ramping and ED length of stay.ResultsA significant decline in POST performance was observed across the study period, with the mean difference between pre– and post–COVID-19 periods being 13.1min (95% CI, 12.9–13.3min) and 8.9min (95% CI, 8.7–9.1min) for Priority 1 and Priority 2 responses, respectively. POST compliance within 30min dropped from 74% (718,912) pre–COVID-19 to 66% (694,633) during the first wave of COVID-19 and 57% (309,815) post–COVID-19, all below the 90% target. The proportion of patients experiencing access block increased from 10% (91,168) to 17% (87,757) over this same time period. Regression analyses revealed a positive relationship between POST and access block, response time and POST, and ramping and ED length of stay. Before COVID-19, no significant relationship existed between POST and access block for triage category 1 patients, but longer POST was linked to a higher likelihood of access block for categories 2–5. This trend increased across all categories during and post–COVID-19.ConclusionAchieving the POST target of transferring 90% of patients within 30min is becoming more difficult, with performance declining. The strong association of POST with access block suggests that access block is driving ramping increases. To reduce delays, efforts should focus on improving access to ward beds and managing hospital capacity issues.

Interval Cancer Characteristics, Staging and Survival Among National Bowel Cancer Screening Program Participants, Western Australia, 2018: A Retrospective Observational Cohort Study

ObjectiveTo examine the features of interval colorectal cancer (interval CRC) in Western Australia in the context of the National Bowel Cancer Screening Program (NBCSP), including incidence, characteristics and survival by NBCSP participant characteristics.Study DesignRetrospective observational cohort study, analysis of linked National Cancer Screening Register and Western Australian Cancer Registry data.Participants, SettingParticipants in the Western Australian NBCSP (50–74years of age) with negative immunochemical faecal occult blood test (iFOBT) results during the 2018 screening round (1 January 2018–31 December 2018) were followed up for interval CRC diagnoses until 31 December 2020, and for death until 30 September 2022.Main Outcome MeasuresCrude and adjusted incidence rates of interval CRC were analysed overall and by sex, age group and residential socio-economic and remoteness categories. Survival outcomes for people with interval CRC were also assessed.ResultsOf 122,851 NBCSP participants with negative screening results in 2018, 51 people were diagnosed with interval CRC during follow-up (crude incidence rate, 21 per 100,000 person-years; 95% confidence interval [CI], 16–27). The adjusted incidence rate ratio of interval CRC was higher for men than women (adjusted incidence rate ratio [aIRR], 5; 95% CI, 3–11) and for people aged 70–74years than for those aged 50–59years (aIRR, 3; 95% CI, 1–6). Nineteen of 51 interval CRCs were diagnosed 19–24months after negative iFOBT results, 25 were located on the right side of the colon and 34 were adenocarcinomas. Only 13 interval CRCs were stage I tumours at diagnosis. During follow-up (median, 33months; interquartile range, 28–42months), the all-cause mortality rate among the 51 people with interval CRC was 41 per 1000 person-years (95% CI, 18–92), and the colorectal cancer mortality rate was 35 per 1000 person-years (95% CI, 14–83).ConclusionsWe provide a comprehensive analysis of interval CRC staging and clinical characteristics in the context of the NBCSP in Western Australia, facilitating the definition of benchmarks for monitoring programme performance.

Valproate Prescribing for Female Adolescents and Management of the Associated Teratogenicity Risk, Royal Children's Hospital, Melbourne, 2022–2024: A Retrospective Audit of Medical Records Data

ObjectivesTo assess the frequency of valproate prescribing for female patients of childbearing age at the Royal Children's Hospital, Melbourne, and to assess the frequency of documented discussions with these patients about the teratogenicity of valproate and the discussions or prescribing of contraception.Study DesignRetrospective audit of hospital electronic medical records data; analysis of Pharmaceutical Benefits Scheme (PBS) valproate dispensing data.Setting, Participants13- to 18-year-old girls or women prescribed valproate at the Royal Children's Hospital, Melbourne during 29 May 2022–29 May 2024; PBS valproate dispensing data for Australia for the 2023 calendar year.Main Outcome MeasuresCharacteristics of adolescent female patients prescribed valproate; documented discussions of valproate-related teratogenicity, and discussions or prescribing of contraception; population valproate prescribing rates for Australia and by state.ResultsValproate was prescribed for 245 female patients aged 13–18years during 2022–2024 (median age, 16years; interquartile range [IQR], 14–17years); the median prescribed daily dose was 600mg (IQR, 400–800mg; range, 200–2000mg). Valproate was prescribed for treating epilepsy for 221 patients (90%), including 97 (44%) with drug-resistant epilepsy; 160 patients (65%) had neurodevelopmental disabilities. Teratogenicity was discussed with 32 patients (13%), less frequently with patients with a neurodevelopmental disability (9% vs. 20%; odds ratio [OR], 0.41; 95% confidence interval [95% CI], 0.19–0.88). Contraception was discussed with 69 patients (28%); the proportion was larger for patients with neurodevelopmental disabilities (34% vs. 16%; OR, 2.66; 95% CI, 1.37–5.14). Contraception was prescribed for 50 patients (20%); the proportion was larger for patients with neurodevelopmental disabilities (25% vs. 12%; OR, 2.50; 95% CI, 1.18–5.30). The national PBS-subsidised dispensing rate during 2023 was 621 per 100,000 girls and women aged 13–18years; in Victoria it was 556 per 100,000 girls and women aged 13–18years.ConclusionDespite the risk of teratogenicity, valproate was prescribed for a considerable number of female adolescents at the Royal Children's Hospital during 2022–2024 and across Australia during 2023. Its teratogenicity was discussed with few patients, nor were discussions or prescribing contraception frequent. Contraception was more frequently discussed and prescribed for patients with neurodevelopmental disability, but teratogenicity was discussed less often.

Early Cessation of Acetylcysteine Treatment After Paracetamol Overdose (NACSTOP 2): A Non-Inferiority Randomised Controlled Trial

ObjectivesTo determine whether ceasing acetylcysteine treatment for adults with acute paracetamol overdose after at least 12h of the two-bag acetylcysteine regimen is non-inferior to providing the full 20-h two-bag regimen.Study DesignOpen label, non-inferiority randomised controlled trial.SettingEmergency departments of six Australian metropolitan hospitals (four in Melbourne, two in Sydney), 1 December 2019–31 July 2024.ParticipantsAdults who required acetylcysteine treatment following single or staggered paracetamol ingestions whose serum alanine transaminase (ALT) level was below 40IU/L on presentation, and whose ALT levels were below 40IU/L and serum paracetamol concentrations below 20mg/L after 12 h of acetylcysteine treatment.InterventionControl group (standard care): two-bag intravenous acetylcysteine regimen (200mg/kg over 4h, followed by 100mg/kg over 16h). Intervention group: Acetylcysteine stopped at least 12h after treatment initiation and the 20-h infusion period completed with intravenous compound sodium lactate.Main Outcome MeasuresDifference in ALT level between presentation and 20h after acetylcysteine treatment initiation; non-inferiority was defined as the upper limit of the 95% confidence interval (CI) of the difference between median changes in ALT level for the intervention and control groups being less than 3IU/L.ResultsOf 2830 people who presented with paracetamol overdose, 860 received acetylcysteine treatment; 186 people who met both the presentation and 12-h acetylcysteine treatment blood test inclusion criteria (median age, 17years; interquartile range [IQR], 16–23years; 162 women [87%]) were randomly assigned to the intervention (93 participants) and control groups (93 participants). Median acetylcysteine infusion time in the intervention group was 13h (IQR, 13–13 h). The median change in ALT level between arrival and 20h after starting intravenous acetylcysteine treatment was similar for the intervention (−1IU/L; IQR, −4 to 1IU/L) and control groups (0IU/L; IQR, −2 to 2IU/L); the difference in median change (−1IU/L; 95% CI, −2 to 1IU/L) was consistent with the non-inferiority criterion. No patients developed hepatic injury or hepatotoxicity.ConclusionAn abbreviated acetylcysteine treatment regimen was non-inferior to the standard 20-h two-bag regimen for people with paracetamol overdose who were at low risk of hepatic failure.Trial RegistrationACTRN12619001549112 (prospective)

Early Palliative Care and Quality of End-of-Life Care for People With Terminal Cancer, Victoria, 2018–2023: A Retrospective, Population-Based Cohort Study

ObjectivesTo determine how many people who die of cancer in Victoria receive palliative care and early palliative care (more than 3months before death); to assess the impact of early palliative care on the quality of end-of-life care.Study DesignRetrospective, population-based cohort study; analysis of linked Victorian Cancer Registry data and routinely collected data for inpatient, non-admitted health service and emergency department care during the 12months prior to death.Setting, ParticipantsVictorian adults who died of cancer during 1 January 2018–31 January 2023.Main Outcome MeasuresProportions of people who received palliative care (any time) or early palliative care (more than 3months prior to death); likelihood of quality of end-of-life care measures: dying outside an acute hospital; chemotherapy, two or more emergency department visits, two or more hospital admissions during final 30days of life; advance care plan at death.ResultsOf 53,305 people who died of cancer (mean age, 74.8years [standard deviation, 13.0years]; 29,527 men [55.4%]), palliative care was provided for 38,697 (72.6%); 17,409 people (32.7%) received early palliative care. The most frequent palliative care type was palliative approach to care (Z51.5 code; 33,974 people, 63.7%). The overall proportion of people who received palliative care did not change markedly during 2018–2022; the proportion who received early palliative care declined slightly, from 34.8% (95% confidence interval [CI], 33.6–35.9) to 33.0% (95% CI, 31.7–33.8). People who received early palliative care were more likely than people who received late palliative care to have an advance care plan (adjusted odds ratio [aOR], 1.46; 95% CI, 1.38–1.55) and to die outside hospital (aOR, 2.50; 95% CI, 2.37–2.64); they were less likely to have two or more of emergency department presentations (aOR, 0.75; 95% CI, 0.70–0.81), two or more hospital admissions (aOR, 0.58; 95% CI, 0.55–0.61) or chemotherapy (aOR, 0.51; 95% CI, 0.47–0.55) during their final 30days of life.Conclusion72.6% of people who died of cancer in Victoria during 2018–2023 had received palliative care, but only 33% had received it early. End-of-life care may be improved by providing palliative care early. The low early palliative care rate, despite the potential for improved outcomes for people who receive it, indicates that action is needed.

Strengthening Care for Children (SC4C), an Integrated Paediatrician‒General Practitioner Model for Reducing Hospital Referral Rates: a Stepped-Wedge Cluster Randomised Controlled Trial

ObjectivesTo assess the effectiveness of Strengthening Care for Children (SC4C) for reducing the number of referrals by general practitioners of patients under 18years of age to hospital services.Study DesignStepped-wedge cluster randomised trial; data collected for up to 16months after the intervention.SettingGeneral practices in North Western Melbourne and Central and Eastern Sydney primary health networks, 1 May 2021–30 September 2023.ParticipantsGeneral practitioners who worked at least two clinical sessions each week, saw patients under 18years of age, and for whom at least 1 month of referrals data during the control period were available; families of people under 18years attending these practices.InterventionWeekly (6 months) then fortnightly (6 months) general practitioner–paediatrician co-consultations; monthly paediatrician-led case discussions; weekday phone and email support by paediatricians.Main Outcome MeasuresProportion of general practitioner visits in which patients were referred to publicly funded hospital outpatient clinics or emergency departments (patient level), overall and by baseline referral rate. Secondary outcomes: Referrals after completion of the intervention; general practitioner confidence regarding child health care; low value care for frequent childhood conditions; family preference for general practitioner or paediatrician care.ResultsOne hundred and thirty participating general practitioners from 22 general practices conducted 50,101 consultations during the control period; 125 general practitioners from 21 general practices received the intervention and undertook 96,804 consultations. Patients were referred to hospitals in 2.3% of control period consultations and 1.9% of intervention period consultations (risk difference, −0.34 [95% confidence interval {CI}, −0.69 to 0.004] percentage points). Among general practitioners with high referral rates at baseline (5% or higher), patients were referred to hospital outpatient or emergency department in 7.3% of control period consultations and in 3.0% of intervention period consultations (risk difference, −4.28 [95% CI, −6.59 to −1.97] percentage points); the referral rate was also lower after the intervention period (sustainability vs. control periods: 2.9% vs. 5.8%; risk difference, −2.92 [95% CI, −5.36 to −0.48] percentage points). The proportions of general practitioners confident about their knowledge and skills regarding child health care were larger during the intervention than the control period. Quality of care and family preference for general practitioner-led care for their children remained high across the study. No adverse events were recorded.ConclusionStrengthening primary care for children reduces the frequency of hospital referrals of children by general practitioners with high referral rates, increases rates of general practitioner confidence about caring for children and maintains family preference for general practitioner-led care.Trial Registration: Australian New Zealand Clinical Trials Registry ACTRN12620001299998 (prospective)
