Paediatric diabetes-related presentations to emergency departments in Victoria, Australia from 2008 to 2018.

OBJECTIVES: Despite significant treatment advances in paediatric diabetes management, ED presentations for potentially preventable (PP) complications such as diabetic ketoacidosis (DKA) remains a major issue. We aimed to examine the characteristics, rates and trends of diabetes-related ED presentations and subsequent admissions in youth aged 0-19 years from 2008 to 2018. METHODS: Data were obtained from the Victorian Emergency Minimum Dataset and the National Diabetes Register. A diabetes-related ED presentation is defined using the International Statistical Classification of Diseases and Related Health Problems, Tenth Revision, Australian Modification diagnosis codes. 'Non-preventable' presentations were the number of youths with newly diagnosed diabetes, and the remaining are classified as PP diabetes-related presentations. Poisson regression model was used to examine the trends in incidence rate and prevalence. RESULTS: Four thousand eight hundred and seventy-two (59%) of 8220 presentations were PP, 4683 (57%) were for DKA whereas 6200 (82%) required hospital admission. Diabetes-related ED presentations decreased from 38.4 to 27.5 per 100 youth with diabetes per year between 2008 and 2018 (ß = -0.04; confidence interval [CI] -0.04 to -0.03; P < 0.001). Females, those aged 0-4 years and rural youth had higher rates of ED presentations than males, older age groups and metropolitan youth. DKA presentations decreased from 20.1 presentations per 100 youth with diabetes in 2008-2009 to 14.9 presentations per 100 youth with diabetes in 2017-2018. The rate of DKA presentations was 68% higher in rural areas compared to metropolitan areas (incidence rate ratio 1.68; CI 1.59-1.78; P < 0.001). CONCLUSIONS: Although the rates of diabetes-related ED presentations declined, PP diabetes-related presentations and subsequent hospitalisation remain high. Patient level research is required to understand the increased DKA presentations in rural youth.

Primary health care utilization and hospital readmission in children with asthma: a multi-site linked data cohort study.

OBJECTIVES: To (1) describe primary health care utilization and (2) estimate the effect of primary care early follow-up, continuity, regularity, frequency, and long consultations on asthma hospital readmission, including secondary outcomes of emergency (ED) presentations, asthma preventer adherence, and use of rescue oral corticosteroids within 12 months. METHODS: An Australian multi-site cohort study of 767 children aged 3-18 years admitted with asthma between 2017 and 2018, followed up for at least 12 months with outcome and primary care exposure data obtained through linked administrative datasets. We estimated the effect of primary care utilization through a modified Poisson regression adjusting for child age, asthma severity, socioeconomic status and self-reported GP characteristics. RESULTS: The median number of general practitioner (GP) consultations, unique GPs and clinics visited was 9, 5, and 4, respectively. GP care was irregular and lacked continuity, only 152 (19.8%) children visited their usual GP on more than 60% of occasions. After adjusting for confounders, there was overall weak indication of effects due to any of the exposures. Increased frequency of GP visits was associated with reduced readmissions (4-14 visits associated with risk ratio of 0.71, 95% CI 0.50-1.00, p = 0.05) and ED presentations (>14 visits associated risk ratio 0.62, 95% CI 0.42-0.91, p = 0.02). CONCLUSIONS: Our study demonstrates that primary care use by children with asthma is often irregular and lacking in continuity. This highlights the importance of improving accessibility, consistency in care, and streamlining discharge communication from acute health services.

Exploring gaps and opportunities in primary care following an asthma hospital admission: a multisite mixed-methods study of three data sources.

OBJECTIVE: Explore gaps and opportunities in primary care for children following a hospital admission for asthma. DESIGN: Exploratory mixed-methods, using linked hospital and primary care administration data. SETTING: Eligible children, aged 3-18 years, admitted to one of three hospitals in Victoria, Australia between 2017 and 2018 with a clinical diagnosis of asthma. RESULTS: 767 caregivers of eligible children participated, 39 caregivers completed a semistructured interview and 277 general practitioners (GPs) caring for 360 children completed a survey. Over 90% (n=706) of caregivers reported their child had a regular GP. However, few (14.1%, n=108) attended a GP in the 24 hours prior to index admission or in the 7 days after (35.8%, n=275). Children readmitted for asthma (34.2%, n=263), compared with those not readmitted (65.8%, n=504), were less likely to have visited a GP in the non-acute phase of their asthma in the 12 months after index admission (22.1% vs 42.1%, respectively), and their GP was more likely to report not knowing the child had an asthma admission (52.8% vs 39.2%, respectively). Fewer GPs reported being extremely confident managing children with poorly controlled asthma (11.9%, n=43) or post-discharge (16.7%, n=60), compared with children with well-controlled asthma (36.4%, n=131), with no difference by child readmission status. CONCLUSIONS: Given the exploratory design and descriptive approach, it is unknown if the differences by child readmission status have any causal relationship with readmission. Nonetheless, improving preventative patterns of primary care visits, timely communication between hospitals and primary care providers, and guideline concordant care by GPs are needed.

Time trends in adrenaline auto-injector dispensing patterns using Australian Pharmaceutical Benefits Scheme data.

AIM: Adrenaline auto-injector (AAI) dispensing data, a community-based proxy for number of individuals at risk of anaphylaxis, provides complementary information on time trends of anaphylaxis risk in addition to hospital admission data. We examined trends of AAI dispensing over a 10-year period (from January 2005 to December 2014) in Australia. METHODS: Individuals with dispensed AAI were identified from a 10% random sample of Australian Pharmaceutical Benefits Scheme (PBS) data. PBS is the Australian national drug subsidy programme covering all Australians. Cumulative incidence and incidence rates of individuals with AAI were calculated. We assessed difference by age, sex, state and time trends. RESULTS: The cumulative incidence of individuals with AAI in 2005-2014 was 75.43/100 000 (95%CI 75.07-75.80/100 000). Incidence rate of individuals with AAI increased from 2005 to 2014 (from 71.47 to 82.07 per 100 000 person-years) although this varied by state. Over the time assessed, there was a shift to more prescriptions being provided by general practitioners (GP) rather than specialists. Children (0-19 years) were more likely to have been prescribed an AAI from a specialist and adults from a GP. CONCLUSION: Overall, an increase in dispensed AAI mirrored other evidence for a rising prevalence of allergy. This increase could also reflect changes in prescribing practices or increased awareness and education of health-care professionals on anaphylaxis and indications for prescribing AAI. The rising rate of AAI prescribed by GPs compared to decreasing rates by specialists suggests a changing response of the Australian health-care system to the increased burden of anaphylaxis.

Challenges of using asthma admission rates as a measure of primary care quality in children: An international comparison.

OBJECTIVES: To demonstrate the challenges of interpreting cross-country comparisons of paediatric asthma hospital admission rates as an indicator of primary care quality. METHODS: We used hospital administrative data from >10 million children aged 6-15 years, resident in Austria, England, Finland, Iceland, Ontario (Canada), Sweden or Victoria (Australia) between 2008 and 2015. Asthma hospital admission and emergency department (ED) attendance rates were compared between countries using Poisson regression models, adjusted for age and sex. RESULTS: Hospital admission rates for asthma per 1000 child-years varied eight-fold across jurisdictions. Admission rates were 3.5 times higher when admissions with asthma recorded as any diagnosis were considered, compared with admissions with asthma as the primary diagnosis. Iceland had the lowest asthma admission rates; however, when ED attendance rates were considered, Sweden had the lowest rate of asthma hospital contacts. CONCLUSIONS: The large variations in childhood hospital admission rates for asthma based on the whole child population reflect differing definitions, admission thresholds and underlying disease prevalence rather than primary care quality. Asthma hospital admissions among children diagnosed with asthma is a more meaningful indicator for inter-country comparisons of primary care quality.

Trends in rates and inequalities in paediatric admissions for Ambulatory Care Sensitive Conditions in Victoria, Australia (2003 to 2013).

AIM: To examine 10-year trends and inequalities in paediatric admission rates for acute and chronic Ambulatory Care Sensitive Conditions (ACSCs) in Victoria, Australia. METHODS: Secondary data analysis of the Victorian Admitted Episodes Dataset of children aged 0-17 years and 11 months admitted with a principal diagnosis of acute ACSCs: gastroenteritis/dehydration, dental conditions and urinary tract infections (UTIs) or chronic ACSCs: asthma and diabetic ketoacidosis, from 2003 to 2013. Main outcome measure was trends in paediatric hospital admission rates for ACSCs (per 1000 population). RESULTS: Over the 10 years, hospital admission rates remained consistently high for asthma and dental conditions. Children from socioeconomically disadvantaged areas were more likely to be admitted for all acute conditions over time. Dental conditions were the only ACSC associated with increased rates of admissions in regional areas. CONCLUSIONS: Inequalities in paediatric hospital admissions exist for acute conditions and have not changed from 2003 to 2013; disadvantaged Victorian children were more likely to be admitted to hospital at each time point. More equitable access to medical and dental care is needed. Primary care (medical and dental) should be a critical platform to address socio-economic differences and effectively prevent avoidable hospital admissions in children.

Strengthening care for children: pilot of an integrated general practitioner-paediatrician model of primary care in Victoria, Australia.

Objective The aim of this study was to assess the acceptability of a novel, integrated general practitioner (GP)-paediatrician model of care, aiming to reduce referrals to hospitals and improve primary care quality. Methods A pre-post study was conducted with five general practice clinics in north-west Melbourne. Over 12 months, 49 GPs and 896 families participated in the intervention that included weekly to fortnightly paediatrician-GP co-consultation sessions at the general practice, monthly case discussions and telephone or email clinical support for GPs. GPs and families completed surveys or interviews at three time points (before the intervention, after running the model for 4 months and at the end of the implementation). Non-identifiable consultation data were extracted from general practice medical records. Results All GPs found the model acceptable. Although not significant, there was a trend towards a lower proportion of referrals to private paediatricians after the intervention (from 34% to 20%) and emergency departments (from 19% to 12%). Outpatient clinic referrals remained steady, and then increased as the paediatrician left the clinics (31% vs 47% before and after the intervention respectively). Unnecessary prescribing of acid suppression medications decreased by 20% (from 29% to 9%). GPs reported improved confidence in paediatric care (88% vs 100% before and after the intervention respectively). Families reported increased confidence in GP care (78% vs 94% before and after the intervention respectively). Model cost estimates were A$172 above usual care per child seen in the co-consultations. Conclusions This novel model of care is acceptable to GPs and families and may improve access and quality of paediatric care. What is known about the topic? A GP-paediatrician integrated model of care appears effective in reducing hospital burden in England, but has not been implemented in Australia. What does this paper add? This pilot, an Australian first, found that a GP-paediatrician integrated model of care is feasible and acceptable in Australia's primary healthcare system, improves GP confidence and quality of paediatric care, may reduce paediatric referrals to outpatient clinics and emergency departments and improves family confidence in, and preference for, GP care. What are the implications for practitioners? This model may reduce hospital burden and improve quality in GP paediatric care while potentially producing cost savings for families and the healthcare system.

Non-indicated acid-suppression prescribing in a tertiary paediatric hospital: An audit and costing study.

AIM: To quantify (i) indicated versus non-indicated prescribing of acid-suppression therapies (AST) in a tertiary paediatric hospital; (ii) patient, provider and hospital factors associated with non-indicated prescribing; and (iii) medication costs. METHODS: This was a prospective, electronic medical audit conducted at The Royal Children's Hospital (RCH) Melbourne in August-September 2016. Proton pump inhibitor (PPI) and histamine-2 receptor antagonist (H2 RA) prescriptions were extracted, with relevant patient, provider and hospital data. Logistic regression analysis of variables associated with indicated and non-indicated prescribing was undertaken. Costs of indicated and non-indicated prescriptions were estimated, with annual costs projected. RESULTS: There was more non-indicated than indicated prescribing across inpatient, outpatient and emergency department settings. Of the total 303 prescriptions analysed, 238 (78.5%) were non-indicated. Gastrostomy presence (odds ratio (OR) 5.51 (1.96-15.46), P = 0.001), consultant providers (OR 2.69 (1.23-5.87), P = 0.01) and inpatient setting (OR 2.35 (1.16-4.77), P = 0.02) were all associated with a higher likelihood of non-indicated prescribing. The child having a predisposing diagnosis was significantly associated with indicated prescribing (OR 0.41 (0.21-0.80), P = 0.009). A total of 75% of hospital and patient spending was for non-indicated prescriptions. Annual costs of non-indicated AST for Melbourne's RCH were projected to be $15 493. CONCLUSIONS: Non-indicated acid-suppression prescribing is common in a tertiary paediatric hospital and associated with gastrostomy presence, consultant providers and inpatient status. Future research should use qualitative methods to understand clinician and patient drivers of prescribing and use this information to develop and test targeted solutions to reduce non-indicated AST prescribing.

Paediatric mental and physical health presentations to emergency departments, Victoria, 2008-15.

OBJECTIVES: To identify trends in presentations to Victorian emergency departments (EDs) by children and adolescents for mental and physical health problems; to determine patient characteristics associated with these presentations; to assess the relative clinical burdens of mental and physical health presentations. DESIGN: Secondary analysis of Victorian Emergency Minimum Dataset (VEMD) data. Participants, setting: Children and young people, 0-19 years, who presented to public EDs in Victoria, 2008-09 to 2014-15. MAIN OUTCOME MEASURES: Absolute numbers and proportions of mental and physical health presentations; types of mental health diagnoses; patient and clinical characteristics associated with mental and physical health presentations. RESULTS: Between 2008-09 and 2014-15, the number of mental health presentations increased by 6.5% per year, that of physical health presentations by 2.1% per year; the proportion of mental health presentations rose from 1.7% to 2.2%. Self-harm accounted for 22.5% of mental health presentations (11 770 presentations) and psychoactive substance use for 22.3% (11 694 presentations); stress-related, mood, and behavioural and emotional disorders together accounted for 40.3% (21 127 presentations). The rates of presentations for self-harm, stress-related, mood, and behavioural and emotional disorders each increased markedly over the study period. Patients presenting with mental health problems were more likely than those with physical health problems to be triaged as urgent (2014-15: 66% v 40%), present outside business hours (36% v 20%), stay longer in the ED (65% v 82% met the National Emergency Access Target), and be admitted to hospital (24% v 18%). CONCLUSIONS: The number of children who presented to Victorian public hospital EDs for mental health problems increased during 2008-2015, particularly for self-harm, depression, and behavioural disorders.
