Negative and positive mental health characteristics of affected family members: Findings from a cross-sectional Australian general population gambling study.

Despite the impact of problem gambling on affected family members (AFMs), there are limited large-scale population level studies identifying the negative mental health (NMH) and positive mental health (PMH) characteristics of AFMs. Furthermore, no study has explored whether PMH characteristics are protective in the relationships between AFM status and NMH characteristics. This study involved secondary data analysis from the Third Social and Economic Impact Study of Gambling in Tasmania. Using a subsample of 1,869 adults (48.30 % male; meanage = 48.48; 4.67 % AFMs), this study aimed to explore whether: (1) AFM status is associated with NMH (depression, anxiety, panic, post-traumatic stress disorder, social anxiety, binge drinking, tobacco use, and drug use symptoms) and PMH (quality of life [QOL], personal growth/autonomy, interpersonal/social skills, coping skills) characteristics after separately controlling for sociodemographic, problem gambling severity, and other NMH characteristics; (2) PMH characteristics moderate (buffer) the relationships between AFM status and NMH characteristics; and (3) gender influences these relationships. AFM status, defined as exposure to family member gambling problems, significantly positively predicted NMH characteristics (depression, anxiety, panic, PTSD, and tobacco use symptoms) and negatively predicted QOL (physical, social) and planning coping. The strength of these relationships generally attenuated after controlling for various covariates. Gender did not moderate these relationships. Religious coping exacerbated the relationship between AFM status and panic disorder symptoms. These findings can inform the development of intervention initiatives for family members exposed to gambling problems. Future population-representative research is required using a range of affected other types, longitudinal study designs, and more comprehensive measures.

Creating an interactive map visualising the geographic variations of the burden of diabetes to inform policymaking: An example from a cohort study in Tasmania, Australia.

OBJECTIVES: To visualise the geographic variations of diabetes burden and identify areas where targeted interventions are needed. METHODS: Using diagnostic criteria supported by hospital codes, 51,324 people with diabetes were identified from a population-based dataset during 2004-2017 in Tasmania, Australia. An interactive map visualising geographic distribution of diabetes prevalence, mortality rates, and healthcare costs in people with diabetes was generated. The cluster and outlier analysis was performed based on statistical area level 2 (SA2) to identify areas with high (hot spot) and low (cold spot) diabetes burden. RESULTS: There were geographic variations in diabetes burden across Tasmania, with highest age-adjusted prevalence (6.1%), excess cost ($2627), and annual costs per person ($5982) in the West and Northwest. Among 98 SA2 areas, 16 hot spots and 25 cold spots for annual costs, and 10 hot spots and 10 cold spots for diabetes prevalence were identified (p<0.05). 15/16 (94%) and 6/10 (60%) hot spots identified were in the West and Northwest. CONCLUSIONS: We have developed a method to graphically display important diabetes outcomes for different geographical areas. IMPLICATIONS FOR PUBLIC HEALTH: The method presented in our study could be applied to any other diseases, regions, and countries where appropriate data are available to identify areas where interventions are needed to improve diabetes outcomes.

The impact of COVID-19 on community mental health: lessons learned from Tasmania, Australia.

BACKGROUND: The COVID-19 pandemic had a significant impact on community mental health globally and widened pre-existing health and social inequities. Tasmania, Australia has one of the highest rates of mental ill health and socioeconomic disadvantage in the country. Whilst Tasmania experienced a delayed and reduced physical presence of COVID-19 compared to other states and territories, mental health impacts remain. It is necessary to understand such impacts to inform policy, practice, and recommendations to enhance the mental health service sector and prevent future mental health burden. This qualitative study aimed to explore expert mental health stakeholders' perspectives of the impact of COVID-19 on: (1) the mental health of people living in Tasmania, and (2) mental health services. METHOD: Semi-structured interviews with 12 expert mental health stakeholders across Tasmania were conducted. This sample was well-positioned to comment on the impact of COVID-19 on community mental health and provide recommendations to enhance the sector. Interviews were thematically analysed. RESULTS: Three subthemes exploring the COVID-19 impact on mental health were included: (1) anxiety, distress, and isolation; (2) varying presentations across age groups; and (3) increased complexity. Four key themes capturing the COVID-19 impact on mental health services were identified: (1) transition to telehealth; (2) increased service demand; (3) spotlight on service gaps; and (4) local workforce shortages. CONCLUSIONS: The pandemic has highlighted existing gaps across the community mental health service sector, and exacerbated existing psychosocial/structural stressors resulting in increased presentations and complexity of mental illness among the community, particularly for youth. Existing treatment gaps and inequities in service access, engagement, and mental health outcomes will persist if not addressed. Recommendations have been provided to inform community mental health service planning, policy, design, access, and provision, and improve wellbeing.

Trends and associations between maternal characteristics and infant birthweight among Indigenous and non-Indigenous people in Tasmania, Australia: a population-based study.

OBJECTIVE: This study aimed to investigate the trends and associations of maternal characteristics and birthweight among Indigenous and non-Indigenous infants. STUDY DESIGN: This was a retrospective population-based study. METHODS: Fourteen years (2005-2018) of birthweight and perinatal health data of live-born singletons and their mothers obtained from the Tasmanian Data Linkage Unit were used to assess the trends and associations between maternal characteristics and infant birthweight using regression modelling. RESULTS: Compared with non-Indigenous mothers (n = 76,750), Indigenous mothers (n = 3805) had a significantly higher prevalence of risk factors during the 14-year period. Although the prevalence of prepregnancy obesity and gestational diabetes mellitus (GDM) markedly increased in both groups, the rate of increase was higher (P < 0.001) for Indigenous than non-Indigenous mothers. Smoking, alcohol consumption and illegal drug use during pregnancy reduced over the years, and there was no significant difference in the rate of reduction between the groups. Large-for-gestational-age (LGA) births increased while small-for-gestational-age (SGA) births decreased in both groups over time. In addition, high birthweight (HBW) births decreased while low birthweight (LBW) births increased. The rates of increase in LGA and LBW births and the rates of decrease in SGA and HBW births were significantly higher in Indigenous mothers compared with non-Indigenous mothers (P < 0.001 for all). The association between Indigenous ethnicity and LBW and SGA births weakened after adjusting for other confounding maternal and perinatal variables. LBW and SGA were positively associated with Indigenous ethnicity, age <18 years, smoking, alcohol consumption and illegal drug use, pre-eclampsia, underweight prepregnancy body mass index and low socio-economic status. Women with higher parity, pre-existing diabetes and prepregnancy overweight or obesity were more likely to give birth to an infant with HBW or LGA. CONCLUSIONS: The prevalence of risk factors for abnormal birthweight is higher among Tasmanian Indigenous mothers, contributing to a gap in birthweight outcomes between Indigenous and non-Indigenous infants. The dramatic increase in prepregnancy obesity and GDM in both groups highlight the importance of screening and management of GDM during pregnancy. Comprehensive programmes co-designed and co-managed in consultation with Indigenous people are needed to support healthy lifestyle choices among Indigenous women to address the barriers to individuals adopting behaviour change and to help close the health outcomes-related gap between Indigenous and non-Indigenous mothers and infants.

Keratinocyte carcinomas, area-level socioeconomic status and geographic remoteness in Tasmania: cross-sectional associations and temporal trends.

OBJECTIVE: This article aims to examine cross-sectional associations and assess temporal trends in keratinocyte carcinoma (KC) incidence by area-level socioeconomic status (SES) and geographic remoteness in Tasmania, Australia. METHODS: KCs-basal cell carcinoma (BCC) and cutaneous squamous cell carcinoma (SCC)-registered by the Tasmanian Cancer Registry were assigned to area-level SES and remoteness area. Incidence rate ratios (2014-2018) were estimated using Poisson regression. Average annual percentage changes (2001-2018) were estimated using the Joinpoint Regression Program. RESULTS: BCC incidence increased with increasing area-level advantage (p value for trend <0.001), but no trend was found for SCC. SCC incidence was higher in rural than urban areas (p value <0.001), and BCC incidence was slightly lower in rural than urban areas for males (p value = 0.026), but not for females (p value = 0.381). BCC and SCC incidence increased between 2001 and the mid-2010s, when it peaked across most areas. CONCLUSIONS: Associations were found between BCC and higher area-level SES, and between SCC and geographic remoteness. The findings suggest differences in sun exposure behaviours, skin cancer awareness and access to services, or ascertainment bias. IMPLICATIONS FOR PUBLIC HEALTH: Efforts to control and deliver KC services in Tasmania should consider targeting populations with specific area-level characteristics.

Risk of hospital admission or emergency department presentation due to diabetes complications: a retrospective cohort study in Tasmania, Australia.

Objective To estimate the risk of an emergency department (ED)/inpatient visit due to complications in people with diabetes and compare them to their non-diabetes counterparts. Methods This matched retrospective cohort study used a linked dataset in Tasmania, Australia for the 2004-17 period. People with diabetes (n = 45 378) were matched on age, sex and geographical regions with people without diabetes (n = 90 756) based on propensity score matching. The risk of an ED/inpatient visit related to each complication was estimated using negative binomial regression. Results In people with diabetes, the combined ED and admission rates per 10 000 person-years were considerable, especially for macrovascular complications (ranging from 31.8 (lower extremity amputation) to 205.2 (heart failure)). The adjusted incidence rate ratios of ED/inpatient visits were: retinopathy 59.1 (confidence interval 25.8, 135.7), lower extremity amputation 11.1 (8.8, 14.1), foot ulcer/gangrene 9.5 (8.1, 11.2), nephropathy 7.4 (5.4, 10.1), dialysis 6.5 (3.8, 10.9), transplant 6.3 (2.2, 17.8), vitreous haemorrhage 6.0 (3.7, 9.8), fatal myocardial infarction 3.4 (2.3, 5.1), kidney failure 3.3 (2.3, 4.5), heart failure 2.9 (2.7, 3.1), angina pectoris 2.1 (2.0, 2.3), ischaemic heart disease 2.1 (1.9, 2.3), neuropathy 1.9 (1.7, 2.0), non-fatal myocardial infarction 1.7 (1.6, 1.8), blindness/low vision 1.4 (0.8, 2.5), non-fatal stroke 1.4 (1.3, 1.6), fatal stroke 1.3 (0.9, 2.1) and transient ischaemic attack 1.1 (1.0, 1.2). Conclusions Our results demonstrated the high demand on hospital services due to diabetes complications (especially macrovascular complications) and highlighted the importance of preventing and properly managing microvascular complications. These findings will support future resource allocation to reduce the increasing burden of diabetes in Australia.

The first confirmed outbreak of Barmah Forest virus in Tasmania - 2019.

OBJECTIVE: To describe the first outbreak of Barmah Forest virus (BFv) in Tasmania and identify potential vectors for BFv in Tasmania. METHODS: A retrospective descriptive study of BFv notifications in the Tasmanian Notifiable Diseases Database (TNDD) was conducted. Adult mosquitoes were sampled from areas near outbreak cases and pooled samples were tested for BFv. RESULTS: 27 cases of confirmed BFv were recorded in the TNDD between 12 March 1999 and 30 June 2019. Nine cases were recorded between 21 January and 10 May 2019 that were acquired in Tasmania, with eight included in this confirmed outbreak. All outbreak cases resided in or travelled to locations in the Break O'Day Local Government Area and reported no recent interstate travel. No virus was detected in pooled mosquito samples. CONCLUSIONS: This is Tasmania's first confirmed outbreak of BFv. Known BFv vector species were identified in both saltmarsh and urban-fringe brackish saltmarsh larval habitats. BFv was not detected from pooled mosquito samples. IMPLICATIONS FOR PUBLIC HEALTH: Clinicians should consider BFv as a possible diagnosis for presentations with fever and arthritis, and potential mosquito exposure in Tasmania. These findings will guide broadening of prevention-focussed public health messaging.

Serology study of healthcare workers following a hospital-based outbreak of COVID-19 in North West Tasmania, Australia, 2020.

Introduction: Healthcare facilities are high-risk settings for coronavirus disease 2019 (COVID-19) transmission. Early in the COVID-19 pandemic, the first large healthcare-associated outbreak within Australia occurred in Tasmania. Several operational research studies were conducted amongst workers from the implicated hospital campus, to learn more about COVID-19 transmission. Methods: Healthcare workers (HCWs) from the implicated hospital campus were invited to complete an online survey and participate in a serology study. Blood samples for serological testing were collected at approximately 12 weeks (round one) and eight months (round two) after the outbreak. A descriptive analysis was conducted of participant characteristics, serology results, and longevity of antibodies. Results: There were 261 HCWs in round one, of whom 44 (17%) were polymerase chain reaction (PCR) confirmed outbreak cases; 129 of the 261 (49%) participated in round two, of whom 34 (27%) were outbreak cases. The prevalence of positive antibodies at round one was 15% (n = 38) and at round two was 12% (n = 15). There were 15 participants (12%) who were seropositive in both rounds, with a further 9% (n = 12) of round two participants having equivocal results after previously being seropositive. Six HCWs not identified as cases during the outbreak were seropositive in round one, with three still seropositive in round two. Of those who participated in both rounds, 68% (n = 88) were seronegative at both time points. Discussion: Our findings demonstrate that serological testing after this large healthcare-associated COVID-19 outbreak complemented the findings of earlier diagnostic testing, with evidence of additional infections to those diagnosed when use of PCR testing had been restricted. The results also provide evidence of persisting SARS-CoV-2 antibody response eight months after an outbreak in an unvaccinated population. The high proportion of HCWs who remained seronegative is consistent with low community transmission in Tasmania after this outbreak.

Risk of subsequent keratinocyte carcinomas after a first diagnosis in Tasmania, Australia.

BACKGROUND/OBJECTIVE: A history of keratinocyte carcinoma (KC) is a risk factor for further KCs, but population-based studies quantifying the risk are lacking in Australia. We aimed to describe the risk of subsequent KCs after first KCs in the Australian state of Tasmania. METHODS: Tasmanian residents identified in the Tasmanian Cancer Registry with a first histologically confirmed basal cell carcinoma (BCC), squamous cell carcinoma (SCC) or synchronous BCC and SCC (within 3 months) between January 1985 and December 2013 were followed up for at least 5 years for the development of a subsequent KC. Cumulative risk, incidence rates and standardised incidence ratios (SIRs) were calculated. RESULTS: Those first diagnosed with BCC-only, SCC-only or synchronous BCC and SCC had (i) 5-year cumulative risks of subsequent KCs of 32%, 29% and 51%, (ii) annualised 5-year incidence rates of 8100/100,000 person-years at risk (PYR), 7747/100,000 PYR and 16,634/100,000 PYR and (iii) SIRs of 10.6 (95% CI: 10.5-10.6), 12.5 (95% CI: 12.4-12.6) and 313.0 (95% CI: 305.2-321.1), respectively. Risk estimates increased substantially when multiple (two or more) lesions of any type were diagnosed synchronously. CONCLUSIONS: In the first Australian population-based study to describe the risk of subsequent KCs according to histological types, around one in three Tasmanians diagnosed with first KCs were diagnosed with subsequent KCs within 5 years. The risk of subsequent KCs was higher among those with a history of multiple synchronous lesions, especially if they included both BCC and SCC lesions.

Costs of major complications in people with and without diabetes in Tasmania, Australia.

Objective We set out to estimate healthcare costs of diabetes complications in the year of first occurrence and the second year, and to quantify the incremental costs of diabetes versus non-diabetes related to each complication. Methods In this cohort study, people with diabetes (n = 45 378) and their age/sex propensity score matched controls (n = 90 756) were identified from a linked dataset in Tasmania, Australia between 2004 and 2017. Direct costs (including hospital, emergency room visits and pathology costs) were calculated from the healthcare system perspective and expressed in 2020 Australian dollars. The average-per-patient costs and the incremental costs in people with diabetes were calculated for each complication. Results First-year costs when the complications occurred were: dialysis $78 152 (95% CI 71 095, 85 858), lower extremity amputations $63 575 (58 290, 68 688), kidney transplant $48 487 (33 862, 68 283), non-fatal myocardial infarction $30 827 (29 558, 32 197), foot ulcer/gangrene $29 803 (27 183, 32 675), ischaemic heart disease $29 160 (26 962, 31 457), non-fatal stroke $27 782 (26 285, 29 354), heart failure $27 379 (25 968, 28 966), kidney failure $24 904 (19 799, 32 557), angina pectoris $18 430 (17 147, 19 791), neuropathy $15 637 (14 265, 17 108), nephropathy $15 133 (12 285, 18 595), retinopathy $14 775 (11 798, 19 199), transient ischaemic attack $13 905 (12 529, 15 536), vitreous hemorrhage $13 405 (10 241, 17 321), and blindness/low vision $12 941 (8164, 19 080). The second-year costs ranged from 16% (ischaemic heart disease) to 74% (dialysis) of first-year costs. Complication costs were 109-275% higher than in people without diabetes. Conclusions Diabetes complications are costly, and the costs are higher in people with diabetes than without diabetes. Our results can be used to populate diabetes simulation models and will support policy analyses to reduce the burden of diabetes.

Why some do but too many don't? Barriers and enablers to physical activity in regional Tasmania - an exploratory, mixed-methods study.

BACKGROUND: The interconnectedness of physical inactivity and sedentarism, obesity, non-communicable disease (NCD) prevalence, and socio-economic costs, are well known. There is also strong research evidence regarding the mutuality between well-being outcomes and the neighbourhood environment. However, much of this evidence relates to urban contexts and there is a paucity of evidence in relation to regional communities. A better understanding of available physical activity (PA) infrastructure, its usage, and community perceptions regarding neighbourhood surroundings, could be very important in determining requirements for health improvement in regional communities. The aims of this research were to 1. Explore and evaluate the public's perception of the PA environment; and 2. Evaluate the quantity, variety, and quality of existing PA infrastructure in regional Northwest (NW) Tasmania. METHODS: A mixed methods approach guided data collection, analysis, and presentation. Quality of PA infrastructure was assessed using the Physical Activity Resource Assessment (PARA) instrument and public perception about PA environment was evaluated using the International Physical Activity Questionnaire - Environmental (IPAQ-E) module. Quantitative data were analysed using descriptive summative methods and a team-based researcher triangulation approach was utilised for qualitative data. RESULTS: Overall, a wide array of high-quality PA infrastructure (with minimal incivilities such as auditory annoyance, litter, graffiti, dog refuse, and vandalism etc.) was available. Survey respondents rated neighbourhoods positively. The overall quality of PA infrastructure, rated on a scale from 0 to 3, was assessed as high (all rated between 2 to 3) with minimal incivilities (rated between 0 and 1.5). Of note, survey respondents confirmed the availability of numerous free-to-access recreational tracks and natural amenities across the 3 local government areas (LGAs) studied. Importantly, most respondents reported minimal disruption to their routine PA practices due to the COVID-19 pandemic. CONCLUSION: This exploratory research confirmed the availability of a wide range of high-quality PA infrastructure across all three LGAs and there was an overwhelming public appreciation of this infrastructure. The challenge remains to implement place-based PA interventions that address extant barriers and further increase public awareness and utilisation of high-quality PA infrastructure.

Randomised controlled trial of active case management to link hepatitis C notifications to treatment in Tasmania, Australia: a study protocol.

INTRODUCTION: By subsidising access to direct acting antivirals (DAAs) for all people living with hepatitis C (HCV) in 2016, Australia is positioned to eliminate HCV as a public health threat. However, uptake of DAAs has declined over recent years and new initiatives are needed to engage people living with HCV in care. Active follow-up of HCV notifications by the health department to the notifying general practitioner (GP) may increase treatment uptake. In this study, we explore the impact of using hepatitis C notifications systems to engage diagnosing GPs and improve patient access to treatment. METHODS AND ANALYSIS: This study is a randomised controlled trial comparing enhanced case management of HCV notifications with standard of care. The intervention includes phone calls from a department of health (DoH) specialist HCV nurse to notifying GPs and offering HCV management support. The level of support requested by the GP was graded in complexity: level 1: HCV information only; level 2: follow-up testing advice; level 3: prescription support including linkage to specialist clinicians and level 4: direct patient contact. The study population includes all GPs in Tasmania who notified HCV diagnosis to the DoH between September 2020 and December 2021. The primary outcome is proportion of HCV cases who initiate DAAs after 12 weeks of HCV notification to the health department. Secondary outcomes are proportion of HCV notifications that complete HCV RNA testing, treatment workup and treatment completion. Multiple logistic regression modelling will explore factors associated with the primary and secondary outcomes. The sample size required to detect a significant difference for the primary outcome is 85 GPs in each arm with a two-sided alpha of 0.05% and 80% power. ETHICS AND DISSEMINATION: The study was approved by University of Tasmania's Human Research Ethics Committee (Protocol ID: 18418) on 17 December 2019. Results of the project will be presented in scientific meetings and published in peer-reviewed journals. TRIAL REGISTRATION NUMBER: NCT04510246. TRIAL PROGRESSION: The study commenced recruitment in September 2020 and end of study expected December 2021.

Learning from the first 12 months of the Tasmanian Trauma Registry.

The Tasmanian Trauma Registry began collecting data in April 2020 and in April 2021 the first 12 months' data were submitted to the Australia New Zealand Trauma Registry. In this perspective, we share the lessons we have learned in establishing a trauma registry and acknowledge how important support from the broader trauma community has been in allowing Tasmania to participate in national benchmarking and quality assurance processes.

Incremental healthcare expenditure attributable to diabetes mellitus: A cost of illness study in Tasmania, Australia.

AIMS: To quantify the incremental direct medical costs in people with diabetes from the healthcare system perspective; and to identify trends in the incremental costs. METHODS: This was a matched retrospective cohort study based on a linked data set developed for investigating chronic kidney disease in Tasmania, Australia. Using propensity score matching, 51,324 people with diabetes were matched on age, sex and residential area with 102,648 people without diabetes. Direct medical costs (Australian dollars 2020-2021) due to hospitalisation, Emergency Department visits and pathology tests were included. The incremental costs and cost ratios between mean annual costs of people with diabetes and their controls were calculated. RESULTS: On average, people with diabetes had healthcare costs that were almost double their controls ($2427 [95% CI 2322-2543]; ratio 1.87 [95% CI 1.85-1.91]; pooled from 2007-2017). While in the first year of follow-up, the costs of a person with diabetes were $1643 (95% CI 1489-1806); ratio 1.83 (95% CI 1.76-1.92) more than their control, this increased to $2480 (95% CI 2265-2680); ratio 1.69 (95% CI 1.62-1.77) in the final year. Although the incremental costs were higher in older age groups (e.g., ≥70: $2498 [95% CI 2265-2754]; 40-49: $2117 [95% CI 1887-2384]), the cost ratios were higher in younger age groups (≥70: 1.52 [95% CI 1.48-1.56]; 40-49: 2.37 [95% CI 2.25-2.61]). CONCLUSIONS: Given the increasing burden that diabetes imposes, our findings will support policymakers in future planning for diabetes and enable targeting sub-groups with higher long-term costs for possible cost savings for the Tasmanian healthcare system.

Association between socioeconomic status and joint replacement of the hip and knee: a population-based cohort study of older adults in Tasmania.

BACKGROUND: A socioeconomic gradient exists in the utilisation of total hip replacements (THR) and total knee replacements (TKR) for osteoarthritis. However, the relations between socioeconomic status (SES) and time to THR or TKR is unknown. AIM: To describe the association between SES and time to THR and TKR. METHODS: One thousand and seventy-two older adults residing in Tasmania, Australia, were studied. Incident primary THR and TKR were determined by data linkage to the Australian Orthopaedic Association National Joint Replacement Registry. At baseline, each participant's area-level SES was determined using the Index of Relative Socioeconomic Advantage and Disadvantage (IRSAD) from the Australian Bureau of Statistics' 2001 census data. The IRSAD was analysed in two ways: (i) categorised into quartiles, whereby quartile 1 represented the most socioeconomically disadvantaged group; and (ii) the cohort dichotomised at the quartile 1 cut-point. RESULTS: The mean age was 63.0 (±7.5) years and 51% were women. Over the median follow up of 12.9 (interquartile range: 12.2-13.9) years, 56 (5%) participants had a THR and 79 (7%) had a TKR. Compared with the most disadvantaged quartile, less disadvantaged participants were less likely to have a THR (i.e. less disadvantaged participants had a longer time to THR; hazard ratio (HR): 0.56; 95% confidence interval (CI) 0.32, 1.00) but not TKR (HR: 0.90; 95% CI 0.53, 1.54). However, the former became non-significant after adjustment for pain and radiographic osteoarthritis, suggesting that the associations may be mediated by these factors. CONCLUSIONS: The present study suggests that time to joint replacement was determined according to the symptoms/need of the participants rather than their SES.

Outpatient autologous stem cell transplantation in Royal Hobart Hospital, Tasmania: a single-centre, retrospective review in the Australian setting.

BACKGROUND: Several international centres have published their experiences with outpatient autologous stem cell transplantation (ASCT) as treatment of haematological malignancies. AIM: In this single-centre retrospective review, we aim to examine the outcomes of outpatient autograft and review healthcare resource utilisation in the pre-cytopenic period. METHODS: Patients undergoing ASCT in Royal Hobart Hospital, Tasmania between 2008 and 2018 had their records reviewed and key outcomes data collected based on whether they received inpatient/outpatient ASCT. An outpatient ASCT was defined as conditioning as an outpatient; patients could then be managed with an elective admission during the cytopenic period or admission only when clinically indicated. RESULTS: Of 231 ASCT performed, 135 (58%) were as outpatients: 59 used carmustine-etoposide-cytarabine-melphalan conditioning for lymphoma (BEAM-ASCT) and 76 used high-dose melphalan for myeloma and amyloidosis (MEL-ASCT). Approximately one-third of patients undergoing outpatient ASCT were admitted electively during nadir period; the majority of patients required minimal interventions prior to this time. The most common causes for unplanned hospitalisation (which occurred in 71 (80%) of the 89 planned outpatient transplants) were febrile neutropenia (39%) and mucositis (35%). Age was the only risk factor identified to increase risk of requiring unplanned hospitalisation. Use of oral antibiotic prophylaxis reduced febrile neutropenia rates among melphalan outpatient ASCT. Outpatient ASCT led to significantly reduced inpatient bed-days and overall cost (approximately A$13 000-A$16 000) compared with inpatient autografts, with no significant differences in engraftment, rates of febrile neutropenia, intensive care admissions or mortality. CONCLUSION: Outpatient autografts may save healthcare resources without compromising patient outcomes.

Competing risks of death and kidney failure in a cohort of Australian adults with severe chronic kidney disease.

OBJECTIVES: To examine the competing risks of death (any cause) and of kidney failure in a cohort of Australian adults with severe chronic kidney disease. DESIGN: Population-based cohort study; analysis of linked data from the Tasmanian Chronic Kidney Disease study (CKD.TASlink), 1 January 2004 - 31 December 2017. PARTICIPANTS: All adults in Tasmania with incident stage 4 chronic kidney disease (estimated glomerular filtration rate [eGFR], 15-29 mL/min/1.73 m2 ). MAIN OUTCOME MEASURES: Death or kidney failure (defined as eGFR below 10 mL/min/1.73 m2 or initiation of dialysis or kidney transplantation) within five years of diagnosis of stage 4 chronic kidney disease. RESULTS: We included data for 6825 adults with incident stage 4 chronic kidney disease (mean age, 79.3 years; SD, 11.1 years), including 3816 women (55.9%). The risk of death increased with age - under 65 years: 0.18 (95% CI, 0.15-0.22); 65-74 years: 0.39 (95% CI, 0.36-0.42); 75-84 years, 0.56 (95% CI, 0.54-0.58); 85 years or older: 0.78 (95% CI, 0.77-0.80) - while that of kidney failure declined - under 65 years: 0.39 (95% CI, 0.35-0.43); 65-74 years: 0.12 (95% CI, 0.10-0.14); 75-84 years: 0.05 (95% CI, 0.04-0.06); 85 years or older: 0.01 (95% CI, 0.01-0.02). The risk of kidney failure was greater for people with macroalbuminuria and those whose albumin status had not recently been assessed. The risks of kidney failure and death were greater for men than women in all age groups (except similar risks of death for men and women under 65 years of age). CONCLUSIONS: For older Australians with incident stage 4 chronic kidney disease, the risk of death is higher than that of kidney failure, and the latter risk declines with age. Clinical guidelines should recognise these competing risks and include recommendations about holistic supportive care, not just on preparation for dialysis or transplantation.

An Audit of Pre-Pregnancy Maternal Obesity and Diabetes Screening in Rural Regional Tasmania and Its Impact on Pregnancy and Neonatal Outcomes.

Maternal obesity in pregnancy, a growing health problem in Australia, adversely affects both mothers and their offspring. Gestational diabetes mellitus (GDM) is similarly associated with adverse pregnancy and neonatal complications. A low-risk digital medical record audit of antenatal and postnatal data of 2132 pregnant mothers who gave birth between 2016-2018 residing in rural-regional Tasmania was undertaken. An expert advisory group guided the research and informed data collection. Fifty five percent of pregnant mothers were overweight or obese, 43.6% gained above the recommended standards for gestational weight gain and 35.8% did not have an oral glucose tolerance test. The audit identified a high prevalence of obesity among pregnant women and low screening rates for gestational diabetes mellitus associated with adverse maternal and neonatal pregnancy outcomes. We conclude that there is a high prevalence of overweight and obesity among pregnant women in rural regional Tasmania. Further GDM screening rates are low, which require addressing.

AstraZeneca COVID-19 vaccine and Guillain- Barré Syndrome in Tasmania: A causal link?

The emergence of the coronavirus 2019 (COVID-19) pandemic has presented an unprecedented global challenge. Vaccines against COVID have been developed to date. Covid-19 has been linked with the development of Guillain-Barre Syndrome (GBS), a rare immune-mediated demyelinating neuropathy. We report three cases of Guillain-Barre Syndrome and one case of Chronic Inflammatory Demyelinating Polyneuropathy (CIDP), presenting to a Tasmanian hospital, and review 15 other reported cases and discuss likely immunopathology. Nearly all reported cases of post-COVID-19 vacciation inflammatory demyelinating polyneuropathy are linked to AstraZeneca vaccination and a variant with bifacial weakness is the most reported form of GBS globally.

Island medicine: using data linkage to establish the kidney health of the population of Tasmania, Australia.

OBJECTIVE: To report (using linked laboratory data) the incidence, prevalence and geographic variation of chronic kidney disease (CKD) across the whole island population of Tasmania, Australia. METHODS: A retrospective cohort study (the Tasmanian Chronic Kidney Disease study (CKD.TASlink)) using linked data from five health and two pathology datasets from the island state of Tasmania, Australia between 1/1/2004 and 31/12/2017. We used data on 460,737 Tasmanian adults (aged 18 years and older, representing 86.8% of the state's population) who had a serum creatinine measured during the study period. We defined CKD as per Kidney Disease Outcomes Quality Initiative, requiring two measures of estimated glomerular filtration rate (eGFR) <60 mL/min/1.73m2, at least three months apart. Kidney replacement therapy (KRT) included dialysis or kidney transplantation. RESULTS: We identified 56,438 Tasmanians with CKD during the study period, equating to an age-standardised annual incidence of 1.0% and a prevalence of 6.5%. These figures were higher in women, older Tasmanians and people living in the North-West region of Tasmania. Testing for urinary albumin:creatinine ratio is increasing, with 28.5% of women and 30.8% of men with stage 3 CKD having both an eGFR and uACR in 2017. Use of KRT was consistently seen in >65% of Tasmanians with eGFR <15 mL/min/1.73m2. CONCLUSION: There is geographic and gender variation in the incidence and prevalence of CKD, but it is reassuring to see that the majority of people with end-stage kidney failure are actually receiving treatment with dialysis or transplantation.
