Effect of pulmonary rehabilitation on all-cause mortality in patients with chronic respiratory disease: a retrospective cohort study in an Australian teaching hospital

Abstract Background Pulmonary rehabilitation (PR) is widely recommended for short-term benefits in chronic respiratory diseases, yet long-term outcomes remain uncertain. This retrospective cohort study addresses this gap, comparing 20-year mortality rates between PR participants and matched controls, and hypothesizing that the short-term benefits of PR contribute to improved long-term survival. Methods The 20-year mortality of stable chronic respiratory patients who participated in an outpatient PR program was compared with a matched control group based on the type of lung disease. Demographic and clinical variables, and the dates of deaths, were extracted and compared between two groups with two sample t-test and chi-square tests. Kaplan-Meier plots and Cox regression analyses were employed to evaluate survival differences. Results Between 2000 and 2002, 238 individuals enrolled in a pulmonary rehabilitation (PR) program (58% male, mean age ± SD: 69 ± 8 years, mean FEV1% predicted ± SD: 46 ± 21%). An equal number of people with comparable lung disease were selected as controls (88% COPD, 5% ILD). Controls had lower FEV1% predicted values (mean ± SD: 39 ± 17%, P < 0.001), smoked more (mean ± SD: 48 ± 35 pack-years, P = 0.032), and no differences in age, BMI, sex, and Index of Relative Socio-economic Advantage and Disadvantage (IRSAD). Median (IQR) follow-up time was 68 months (34–123), with 371 (78%) deaths. Univariable (HR = 1.71, p < 0.001) and multivariable (HR = 1.64, p < 0.001) Cox regression found higher mortality risk in controls. Subgroup analysis for COPD replicated these findings (HR = 1.70, P < 0.001). Discussion Despite some methodological limitations, our study suggests that clinically stable patients with chronic respiratory disease who undertake PR may have lower mortality than matched controls. Trial registration Retrospectively registered.

Geographic residence of patients with medication-related osteonecrosis of the jaw.

135 Background: Bone-modifying agents (BMAs) are utilized to reduce the risk of skeletal-related events in patients with bone metastases. Medication-related osteonecrosis of the jaw (MRONJ) is a rare but difficult to treat adverse event of BMAs. There are known patient and treatment related risk factors for development of ONJ, however, little is known on social and geographic risks. In patients with bone metastases and concurrent MRONJ, we seek to describe differences in patient's geographic residence (rural versus urban) with other social factors as secondary outcomes. Methods: We conducted a retrospective chart review of Atrium Health Wake Forest Baptist Comprehensive Cancer Center patients in the date range of 01/01/2013 to 11/01/2023. Included were patients with metastatic breast cancer, metastatic prostate cancer or multiple myeloma who had a diagnosis of MRONJ. We recorded Rural-Urban Commuting Area (RUCA) codes, the Area Deprivation Index (ADI), age, race, ethnicity, smoking status, alcohol use, body mass index, insurance status, type of cancer, type of BMA, and cumulative dosing of BMAs. Patients were defined as rural or urban based on criteria from the health resources and services administration website. Relative socioeconomic advantage versus disadvantage was determined by the patients’ ADIs with a decile rank from 1-10 for state ADIs and a percentile rank of 1-100 for national ADIs. SAS software (version 9.4) was used for data analysis (2023, SAS Institute Inc, Cary, NC). Results: A total of 88 patients met inclusion criteria. 64% of patients lived in urban areas and 36% in rural. Demographic features of the identified patients are listed in table 1. MRONJ patients from both urban and rural areas had an above average national and state ADI, with a trend toward higher ADIs in rural locations compared to urban locations; mean of 6.7 vs 5.3 state ADI and mean 70.6 vs 62.0 national ADI, for rural and urban patients respectively. There were no statistically significant differences between rural and urban patients in any of the demographic or health-related characteristics we examined. Conclusions: Patients with bone metastases and MRONJ in our cohort demonstrate relative socioeconomic disadvantage in comparison to national and state averages. In comparing the rural with urban patients, however, we observed relatively similar profiles. Patient characteristics by rural/urban status.

Social Characteristics of Culturally and Linguistically Diverse Cancer Patients Enrolled in Early Phase Clinical Trials in South Western Sydney

Introduction: Early phase clinical trials (EPCTs) enable access to novel therapies for patients who have exhausted standard of care treatment and contribute a crucial role in drug development and research. Culturally and linguistically diverse (CALD) or socially disadvantaged patients have notably lower rates of participation in these trials. We aimed to characterise the social and cultural demographics of patients enrolled on an EPCT in South Western Sydney. Methods: We conducted a 10-year retrospective review of patients enrolled on a EPCT at Liverpool Hospital. CALD patients were defined as those born overseas or whose preferred language was other than English. The patient residential address was used to calculate distance travelled, and the Index of Relative Socioeconomic Disadvantage (IRSD) and Index of Relative Socioeconomic Advantage and Disadvantage (IRSAD) scores were calculated and used as a surrogate for socioeconomic status (SES). Results: Our study included 233 patients across 39 EPCTs. Ninety-one patients (39%) were identified as CALD. The median IRSD and IRSAD scores were 941 and 944, respectively, with 62.7–67.4% of patients residing in an area with greater disadvantage compared to the median of Australia. The median distance travelled was 17 kilometres with only 12% of participants travelling more than 50 km. CALD patients were more likely to reside in an area of low SES (OR 3.4, 95% CI: 1.8–6.5, p < 0.01) and travelled shorter median distances (10 vs. 23 km) when compared to non-CALD patients. Conclusion: Our study cohort contained a lower proportion of CALD patients and a higher SES than what we might have expected from our local population. Furthermore, there was a trend toward greater SES disadvantage (lower IRSD/IRSAD scores) for the CALD population. This study provides novel Australian data to support the underrepresentation of culturally diverse or disadvantaged patients on EPCTs. Future efforts should be made to reduce barriers to participation and improve equity in clinical trial participation.

Association of Socioeconomic Status and Reasons for Companion Animal Relinquishment.

It is important to understand the reasons for companion animal relinquishment to help reduce the financial and ethical problems arising from too many dogs and cats in shelters. This study investigates the socioeconomic factors and reasons behind companion animal relinquishment in Australia, utilizing data from five animal shelters, over a five-year period (Financial Year 2018/19 to 2022/23). Descriptive statistics reveal that the median Index of Relative Socio-Economic Advantage and Disadvantage (IRSAD) decile of companion animal guardians who relinquished their companion animal was decile 4 out of 10, indicating that they live in areas of lower-than-average socioeconomic status. Cats accounted for 59.4% and dogs for 40.6% of all relinquishments, with more relinquishments from lower socioeconomic deciles (1-5) (cats: 62.6%, dogs: 65.8%). The median age of relinquished cats was 5 months and dogs 16 months, with human factor-related issues (e.g., Housing, Financial Constraints, Human Healthcare) cited in 86% of cases. Descriptive analysis for the five financial years shows a declining trend in numbers of relinquishments, with housing issues (31.2%) identified as the primary reason, followed by ownership decisions (16.2%), financial constraints (11.2%), and human health issues (10.4%). Comparing the reasons for relinquishment between lower (decile 1-5) and higher (decile 6-10) socioeconomic status demonstrated that financial difficulties were a more common reason in lower vs. higher socioeconomic groups, while human health and family-related issues are more common in higher vs. lower socioeconomic groups. These findings highlight the critical role of socioeconomic factors in understanding why people relinquish their companion animals, which can inform targeted interventions to support companion animal welfare across different socioeconomic backgrounds.

Long-Term Effect of Temperature Increase on Liver Cancer in Australia: A Bayesian Spatial Analysis.

While some evidence has potentially linked climate change to carcinogenic factors, the long-term effect of climate change on liver cancer risk largely remains unclear. Our objective is to evaluate the long-term relationship between temperature increase and liver cancer incidence in Australia. We mapped the spatial distribution of liver cancer incidence from 2001 to 2019 in Australia. A Bayesian spatial conditional autoregressive (CAR) model was used to estimate the relationships between the increase in temperature at different lags and liver cancer incidence in Australia, after controlling for chronic hepatitis B prevalence, chronic hepatitis C prevalence, and the Index of Relative Socio-economic Disadvantage. Spatial random effects obtained from the Bayesian CAR model were also mapped. The research showed that the distribution of liver cancer in Australia is spatially clustered, most areas in Northern Territory and Northern Queensland have higher incidence and relative risk. The increase in temperature at the lag of 30 years was found to correlate with the increase in liver cancer incidence in Australia, with a posterior mean of 30.57 [95% Bayesian credible interval (CrI): 0.17, 58.88] for the univariate model and 29.50 (95% CrI: 1.27, 58.95) after controlling for confounders, respectively. The results were not highly credible for other lags. Our Bayesian spatial analysis suggested a potential relationship between temperature increase and liver cancer. To our knowledge, this research marks the first attempt to assess the long-term effect of global warming on liver cancer. If the relationship is confirmed by other studies, these findings may inform the development of prevention and mitigation strategies based on climate change projections. https://doi.org/10.1289/EHP14574.

Socioeconomic determinants of very frequent presentations to emergency departments in New South Wales, Australia: A state wide data linkage study

ObjectivesTo describe the clinical and longitudinal patterns of presentation, and to understand the underlying socioeconomic characteristics of different modes of presentation. DesignRetrospective state-wide data linkage analysis of emergency department (ED) presentations. Patients were included if they were 18 years of age or over and presented to the ED over twenty times within any consecutive 365-day period between January 2015 and December 2020. This analysis used routinely collected data from the Emergency Department Data Collection and Admitted Patient Data Collection. The quintile of Socioeconomic Indexes for Area (SEIFA) defined by Australian Bureau of Statistics was used for equity considerations. Main outcome measuresThe main outcomes of interest included patients’ clinical presentation, demographic information and SEIFA score as represented by Index of Relative Socioeconomic Advantage and Disadvantage (IRSAD) quintiles. ResultsThere were 417,154 presentations and 5,244 patients who met the inclusion criteria. The majority of the presentations were from SEIFA groups 1 (28.2 %) and 2 (35.6 %). The most common presentations were for drug and alcohol (17.5 %), followed by abdominal pathology (11.8 %) and mental health (11.5 %). In the lowest SEIFA group, the main presenting complaints were for drug and alcohol and administrative presentations. While in the highest SEIFA group, the main presentations were for mental health then abdominal pain, followed by drug and alcohol presentations. ConclusionPatients in the lower SEIFA groups tended to be older with lower acuity presentations and were more likely to present to the same facility, more regularly. Patients in the lower SEIFA group were also more likely to present with drug and alcohol and administrative presentations while those in the higher SEIFA groups were more likely to present with mental health presentations. System wide interventions are needed to address the needs of both groups, particularly those from lower socioeconomic backgrounds, who would benefit from improved access to primary care either through access to General Practice or Urgent Care Centres.

How Do Socioeconomic Differences Among Low-Income and Racially Minoritized Students Shape Their Engagement and Access in School Choice Systems?

Socioeconomic differences among low-income and racially minoritized students may be consequential for understanding the dynamics of school choice—especially in high-poverty and racially segregated urban contexts that are often targeted by school choice policies. Yet school choice research largely focuses on differences between groups and relies on measures that broadly categorize students as low-income or not. Drawing on parent interviews in Detroit, this study describes socioeconomic differences among low-income and racially minoritized families and examines how those differences relate to their engagement in the school choice process. While families faced a similar landscape of choice, relied on similar types of resources, and did not have drastically different preferences, relative socioeconomic disadvantages translated to more constrained access and engagement in school choice.

A 3-year retrospective review of hospital admissions involving opioid toxicity in South Australia.

This article aims to characterise hospital admissions involving opioid toxicity across South Australia to guide future implementation and evaluation of risk mitigation strategies. International Classification of Diseases, 10th Edition codes (T40.0-T40.4) were used to identify admissions involving pre-hospital opioid toxicity in public hospitals across South Australia from 1 June 2017 to 30 August 2020. Demographic and episode of care data were extracted and summarised using descriptive statistics. Admission cost estimates were calculated using Independent Hospital Pricing Authority data. A total of 2046 cases met the criteria for inclusion; over half (56%) were female and median age on admission was 44 years (interquartile range 27 years). Where opioid toxicity was the primary diagnosis, 70% of admissions did not specify the responsible opioid and 23% were related to heroin use. One-fifth of admissions occurred outside of metropolitan Adelaide. Individuals living in an area of relative socio-economic disadvantage were over-represented. Over half of admissions required a stay >24 h; 19% were admitted for ≥5 days, 22% required intensive care and ~10% required mechanical ventilation. The total estimated cost of admissions involving opioid toxicity in South Australia over the 3-year period was $18,230,546.50, equating to $5.6 million per annum. These findings highlight the significant personal, fiscal, and systemic impacts of opioid toxicity-related hospital admissions in South Australia and provide a baseline to evaluate the effectiveness of initiatives to reduce opioid-related harm, including real-time prescription monitoring and take-home naloxone supply.

The influence of socioeconomic disadvantage on short- and long-term outcomes after oesophagectomy for cancer: an Australian multicentre study.

Socioeconomic status (SES) affects outcomes following surgery for various cancers. There are currently no Australian studies that examine the role of socioeconomic disadvantage on outcomes following oesophagectomy for cancer. This study assessed whether SES was associated with short-term perioperative morbidity, long-term survival, and oncological outcomes following oesophagectomy across three tertiary oesophageal cancer centres in Australia. A retrospective cohort study was performed comprising all patients who underwent oesophagectomy for cancer across three Australian centres. Patients were stratified into SES groups using the Index of Relative Socioeconomic Advantage and Disadvantage (IRSAD). Outcomes measured included perioperative complication rates, overall survival, and disease-free survival. The study cohort was 462 patients, 205 in the lower SES and 257 in the higher SES groups. The lower SES group presented with more advanced oesophageal cancer stage, a higher rate of T3 (52.6% versus 42.7%, P = 0.038) and N2 disease (19.6% versus 10.5%, P = 0.006), and had a higher rate of readmission within 30 days (11.2% versus 5.4%, P = 0.023). There was no difference in overall survival or disease-free survival between groups. Lower socioeconomic status was associated with more advanced stage and increased risk of early, unplanned readmission following oesophagectomy, but was not associated with a difference in overall or disease-free survival.

Obesity in women giving birth in Victoria, 2010-2019: a retrospective cohort study.

To assess the prevalence of obesity in pregnant women in Victoria, 2010-2019. Retrospective cohort study; analysis of Victorian Perinatal Data Collection data. Women who gave birth in seventeen Victorian Department of Health areas (eight metropolitan, nine regional), 2010-2019. Proportions of births to women with obesity (body mass index ≥ 30 kg/m2), by Department of Health area and year. A total of 710 364 births with records that included the mothers' BMI were recorded in Victoria during 2010-2019. The proportion of births to women with obesity rose from 19.6% (95% confidence interval [CI], 19.3-19.9%) in 2010 to 21.5% (95% CI, 21.2-21.8%) in 2019; the proportion of births to women with normal weight declined from 49.0% (95% CI, 48.6-49.4%) to 46.8% (95% CI, 46.4-47.1%). In metropolitan areas, the proportion of births to women with obesity rose from 17.7% (95% CI, 17.7-17.8%) to 19.4% (95% CI, 19.3-19.4%); in regional areas, it increased from 25.0% (95% CI, 25.0-25.1%) to 29.1% (95% CI, 29.0-29.2%). The increase in prevalence of obesity was greater among women living in the lowest socio-economic standing (Index of Relative Socio-Economic Disadvantage) quintile than for those residing in the quintile of least disadvantage (adjusted rate ratio, 2.16; 95% CI, 2.12-2.20). The proportion of births to Victorian women with obesity rose during 2010-2019, particularly in regional areas. Ensuring that regional health services are adequately resourced to meet the needs of the increasing number of women at risk of obesity during pregnancy is vital.

Long-Term Implications of Socioeconomic Status on Major Adverse Cardiovascular, Cerebrovascular Events (MACCE), and All-Cause Mortality

Socio-economic status (SES) has a large impact on health through a complex interplay of upstream, midstream and downstream factors. However, little is known about the predictive role of SES on long-term major adverse cardiovascular, cerebrovascular events, and mortality (MACCE). To determine the long-term relationship between SES and MACCE for men and women. The secondary endpoint was to determine the relationship between SES and all-cause mortality. A total of 3,034 participants (1,494 women and 1,540 men) were assessed at baseline in the Geelong Osteoporosis Study, a large regional Australian population cohort study. Area-based SES was assessed, utilising the Index of Relative Socio-Economic Disadvantage (IRSD) and grouped into quintiles. The primary endpoint, MACCE, was defined as a composite of myocardial infarction, heart failure hospitalisation, malignant arrhythmias, stroke, and all-cause mortality. The secondary endpoint was all-cause mortality. Baseline data including age, sex, smoking status and alcohol use, and comorbidities were collected between 1993-1997 for women, and 2001-2006 for men, with follow-up over 30 and 22 years, respectively. Logistic regression was utilised to assess MACCE and all-cause mortality outcomes across the SES quintiles. Participants lost to follow-up or with incomplete data collection were excluded leaving 2,173 participants eligible for analysis. SES was associated with MACCE outcomes. Compared with Quintile I (lowest SES stratum), the odds of MACCE for each IRSD stratum were: Quintile II, odds ratio (OR) 0.85 (95% confidence interval [CI] 0.65-1.13); Quintile III, OR 0.69 (95% CI 0.51-0.91); Quintile IV, OR 0.66 (95% CI 0.50-0.88); and, Quintile V, OR 0.55 (95% CI 0.41-0.72). In the adjusted model, an inverse trend was noted, with reducing MACCE outcomes with an increasing SES status; IRSD Quintile II, OR 0.85 (95% CI 0.62-1.17); Quintile III, OR 0.70 (95% CI 0.50-0.97); Quintile IV, OR 0.73 (95% CI 0.52-1.02); and, Quintile V, OR 0.54 (95% CI 0.39-0.74). SES was inversely associated with all-cause mortality; IRSD Quintile II (OR 0.87, 95% CI 0.66-1.16) failed to achieve significance however IRSD Quintile III (OR 0.65, 95% CI 0.48-0.88), Quintile IV (OR 0.59, 95% CI 0.44-0.80) and Quintile V (OR 0.46, 95% CI 0.34-0.62) had a lower risk of mortality compared with Quintile I. In the adjusted model, an inversely proportional trend was noted between SES and all-cause mortality; IRSD Quintile II (OR 0.82, 95% CI 0.59-1.15), IRSD Quintile III (OR 0.63, 95% CI 0.49-0.95), Quintile IV (OR 0.59, 95% CI 0.45-0.90) and Quintile V (OR 0.44, 95% CI 0.31-0.61) had fewer mortality events compared with IRSD Quintile I. Our research indicates that being part of a lower socio-economic stratum is linked to a higher likelihood of experiencing negative cardiovascular and cerebrovascular events, along with an increased risk of overall mortality. SES is an important risk stratification marker for long-term prognosis of cardiovascular diseases and stroke, and warrants further investigation.

Racial and Socioeconomic Disparities Exist in Patients Pursuing Peanut Oral Immunotherapy

BackgroundOral immunotherapy (OIT) is a promising treatment for food allergy. Prior studies demonstrate significant differences among food allergic individuals across race, ethnicity, and socioeconomic groups. Disparities in OIT have not been evaluated. ObjectiveWe assessed disparities in the use of OIT in patients with peanut allergy based on race, ethnicity, and socioeconomic status at a single academic medical center. MethodsWe identified 1028 peanut allergic patients under 18 years of age receiving care in the University of Michigan food allergy clinics. 148 patients undergoing peanut OIT (treatment group) were compared to the 880 patients avoiding peanut (control group). Pertinent demographic and socioeconomic characteristics were compared. ResultsThere were no differences in gender or ethnicity between the OIT and control groups. However, Black patients comprised 18% of the control group but only 4.1% of the OIT treatment group (p<0.0001). The proportion of patients with private insurance was significantly higher in the treatment group compared to control group, 93.2% vs 82.2% (p=0.0004). Finally, the Neighborhood Affluence Index, a Census-based measure of the relative socioeconomic prosperity of a neighborhood, was significantly higher in the OIT group vs. the control group (0.51±0.18 vs 0.47±0.19) (p=0.015), while the Neighborhood Disadvantage Index, a Census-based measure of the relative socioeconomic disadvantage of a neighborhood, was significantly lower (0.082±0.062 vs 0.10±0.093) (p=0.020). ConclusionSignificant racial and economic disparities exist at our institution between peanut allergic individuals who receive OIT and those who do not. Efforts to understand the basis for these disparities are important to ensure patients have equitable access to OIT.

The epidemiology of acute pancreatitis in Tasmania over a 12-year period: Is this a disease of disadvantage?

BackgroundThe global incidence of acute pancreatitis (AP) is increasing, but little information exists about trends in Australia. This study aimed to describe incidence trends, along with clinical and socio-demographic associations, in the state of Tasmania over a recent 12-year period. MethodsThe study cohort was obtained by linking clinical and administrative datasets encompassing the whole Tasmanian population between 2007 and 2018, inclusive. Pancreatitis case definition was based on relevant ICD-10 hospitalization codes, or elevated serum lipase or amylase in pathology data.Age-standardised incidence rates were estimated, overall and stratified by sex, aetiology, and Index of Relative Socio-economic Disadvantage (IRSD). ResultsIn the study period, 4905 public hospital AP episodes were identified in 3503 people. The age-standardised person-based incidence rate across the entire period was 54 per 100,000 per year. Incidence was inversely related to IRSD score; 71 per 100,000 per year in the most disadvantaged quartile compared to 32 in the least disadvantaged. Biliary AP incidence was higher than that of alcohol-related AP, although the greatest incidence was in “unspecified” cases. There was an increase in incidence for the whole cohort (average annual percent change 3.23 %), largely driven by the two most disadvantaged IRSD quartiles; the least disadvantaged quartile saw a slight overall decrease. ConclusionThis is the first Australian study providing robust evidence that AP incidence is increasing and is at the upper limit of population-based studies worldwide. This increased incidence is greatest in socio-economically disadvantaged areas, meriting further research to develop targeted, holistic management strategies.

Metabolic syndrome is prevalent and undiagnosed in clients attending private practice physiotherapy: a cross-sectional study

ObjectivesTo determine the prevalence of metabolic syndrome in clients presenting for primary care physiotherapy within private practice settings, and the factors that may be associated with metabolic syndrome. The secondary aim was to determine client’s attitudes towards lifestyle change. DesignA cross-sectional study in which self-report and biometric data were collected. The study was conducted in physiotherapy private practices across metropolitan and regional areas, Australia. Participants230 clients (mean age 54 (SD18) years, 64% women) presenting for physiotherapy participated. Main outcome measuresParticipant socio-demographic and lifestyle characteristics were collected. Metabolic syndrome presence was determined by the existence of three or more risk factors on physical examination and capillary blood sample: abdominal obesity, hypertension, elevated random blood glucose, elevated triglycerides and/or reduced HDL cholesterol. ResultsThirty-seven percent of participants had metabolic syndrome, but none knew they had it. Metabolic syndrome was associated with older age and poorer socio-economic status and may have been associated with lower levels of physical activity but not diet. Of those identified as having hypertension and elevated triglycerides, many were undiagnosed (56% and 29% respectively). ConclusionMetabolic syndrome is prevalent and undiagnosed in clients attending private practice physiotherapy. Clients felt lifestyle change was important and they were willing to make changes. This study highlights the need for greater screening of metabolic risk factors in primary care and presents an opportunity for physiotherapists in private practice to identify risk and intervene to improve the overall health of their clients and contribute to chronic disease prevention. Contribution of the Paper•Metabolic syndrome is more prevalent in clients attending private practice physiotherapy (37%) compared to the general population (25%).•Older clients from areas of relative socio-economic disadvantage who are no longer employed and are inactive are most at risk.•Physiotherapists can make an impact by detecting metabolic syndrome and then providing advice and prescribing exercise and physical activity, along with referral for appropriate medical or dietary management.

Improved Glycemic Outcomes With Diabetes Technology Use Independent of Socioeconomic Status in Youth With Type 1 Diabetes.

Technology use in type 1 diabetes (T1D) is impacted by socioeconomic status (SES). This analysis explored relationships between SES, glycemic outcomes, and technology use. A cross-sectional analysis of HbA1c data from 2,822 Australian youth with T1D was undertaken. Residential postcodes were used to assign SES based on the Index of Relative Socio-Economic Disadvantage (IRSD). Linear regression models were used to evaluate associations among IRSD quintile, HbA1c, and management regimen. Insulin pump therapy, continuous glucose monitoring, and their concurrent use were associated with lower mean HbA1c across all IRSD quintiles (P < 0.001). There was no interaction between technology use and IRSD quintile on HbA1c (P = 0.624), reflecting a similar association of lower HbA1c with technology use across all IRSD quintiles. Technology use was associated with lower HbA1c across all socioeconomic backgrounds. Socioeconomic disadvantage does not preclude glycemic benefits of diabetes technologies, highlighting the need to remove barriers to technology access.

Measuring the psychosocial wellbeing of Rohingya mothers in Cox’s Bazar, Bangladesh: Psychometric properties of an MHPSS assessment battery

Background Psychosocial research in humanitarian settings has been historically dominated by a focus on distress and disorder. As such, there is a need to establish the validity of instruments for a broad range of psychosocial outcomes, particularly among highly affected and under-represented populations. The current study describes the adaptation and testing of multiple psychosocial instruments among displaced Rohingya mothers in Bangladesh. Methods We used baseline data from 600 mothers of malnourished children aged 2 and under enrolled in an intervention study in Cox’s Bazar, Bangladesh. Instruments assessed distress (items from the International Depression Symptom Scale [IDSS] and Kessler-6 [K-6]); functional impairment (World Health Organization Disability Assessment Schedule [WHODAS]); subjective wellbeing (global Satisfaction With Life [SWL] and Personal Wellbeing Index [PWI]; and, coping (items from the Brief COPE and locally developed coping items). Instruments were piloted and refined, then used for data collection by Bangladeshi-Rohingya interviewer pairs. We conducted exploratory factor analysis, evaluated internal consistency, examined construct validity through correlation with other scales, and used regression models to explore demographic factors associated with psychosocial health. Results Both the WHODAS and coping items fit 2-factor models; other scales were unidimensional. Cronbach’s alphas ranged from .76 to .90 for the refined scales. With the exception of coping, scale correlations supported construct validity; separate measures of the same construct were highly correlated, distress and impairment were moderately correlated, and both were inversely correlated with wellbeing. Correlates of poorer psychosocial health included relative socioeconomic disadvantage, current pregnancy, and being unmarried. Conclusions Most of the standard psychosocial assessment tools performed adequately, but they did not appear to fully capture local experiences and included items of little local relevance. Findings highlight the need for further mixed methods research to develop a rich battery of instruments with cross-cultural validity, particularly for positive outcomes such as coping which was particularly challenging to assess.

Cardiovascular disease hospitalizations among women who undergo fertility treatment

Research questionAre women who receive fertility treatment at increased risk of cardiovascular disease (CVD) hospitalization compared with women who do not? DesignA retrospective cohort study of all women registered for fertility treatment at Monash IVF between 1998 and 2014. This cohort was linked to the Victorian Admitted Episodes Dataset, which contains records of all hospital admissions in the Australian state of Victoria. Age- and Index of Relative Socioeconomic Disadvantage (IRSD)-adjusted relative risks of CVD hospitalization for women who did or did not undergo fertility treatment were determined using Poisson regression. Risks were calculated overall by CVD subtype and stratified by area-based social disadvantage using IRSD fifths, number of stimulated cycles and mean oocytes per cycle. ResultsOf 27,262 women registered for fertility treatment, 24,131 underwent treatment and 3131 did not. No significant difference was found in risk of CVD hospitalization between treated and untreated women overall (adjusted RR 0.93, 95% 0.82 to 1.05) or by CVD subtype. The admission risk for CVD was significantly lower in treated women who had a mean of fewer than five oocytes per cycle (adjusted RR 0.80, 95% CI 0.70 to 0.92) compared with untreated women. Treated women residing in areas within the second IRSD fifth were less likely to be hospitalized for CVD compared with untreated women (age-adjusted RR 0.66, 95% CI 0.49 to 0.89). ConclusionsFertility treatment is not associated with increased risk of CVD hospitalization. Lower risk among some subgroups of treated women may be explained by social disadvantage.

Socio-economic status and access to fluoridated water in Queensland: an ecological data linkage study.

To investigate the relationship between access to fluoridated drinking water and area-level socio-economic status in Queensland. Ecological, geospatial data linkage study. Queensland, by statistical area level 2 (SA2), 2021. Proportion of SA2s and of residents with access to fluoridated drinking water (natural or supplemented); relationship at SA2 level between access to fluoridated water and socio-economic status (Index of Relative Socio-economic Advantage and Disadvantage, IRSAD; Index of Economic Resources, IER). In 2021, an estimated 4 050 168 people (79.4% of the population) and 397 SA2 regions (72.7%) in Queensland had access to fluoridated water. Access was concentrated in the southeastern corner of the state. After adjusting for SA2 population, log area, and population density, the likelihood of access to fluoridated drinking water almost doubled for each 100-rank increase in IRSAD (adjusted odds ratio [aOR], 1.93; 95% confidence interval [CI], 1.59-2.36) or IER (aOR, 1.77; 95% CI, 1.50-2.11). The 2012 decision to devolve responsibility for water fluoridation decisions and funding from the Queensland government to local councils means that residents in lower socio-economic areas are less likely to have access to fluoridated water than those in more advantaged areas, exacerbating their already greater risk of dental disease. Queensland water fluoridation policy should be revised so that all residents can benefit from this evidence-based public health intervention for reducing the prevalence of dental caries.

Socioeconomic representativeness of Australian, Canadian and British cohorts from the paediatric diabetes AdDIT study: comparisons to regional and national data

BackgroundGiven limited data regarding the involvement of disadvantaged groups in paediatric diabetes clinical trials, this study aimed to evaluate the socioeconomic representativeness of participants recruited into a multinational clinical trial in relation to regional and national type 1 diabetes reference populations.MethodsRetrospective, cross-sectional evaluation of a subset of adolescent type 1 diabetes cardiorenal intervention trial (AdDIT) participants from Australia (n = 144), Canada (n = 312) and the UK (n = 173). Validated national measures of deprivation were used: the Index of Relative Socioeconomic Disadvantage (IRSD) 2016 (Australia), the Material Resources (MR) dimension of the Canadian Marginalisation index 2016 (Canada) and the Index of Multiple Deprivation (IMD) 2015 (UK). Representativeness was assessed by comparing the AdDIT cohort’s distribution of deprivation quintiles with that of the local paediatric type 1 diabetes population (regional), and the broader type 1 diabetes population for which the trial’s intervention was targeted (national).ResultsRecruited study cohorts from each country had higher proportions of participants with higher SES, and significant underrepresentation of lower SES, in relation to their national references. The socioeconomic make-up in Australia mirrored that of the regional population (p = 0.99). For Canada, the 2nd least deprived (p = 0.001) and the most deprived quintiles (p < 0.001) were over- and under-represented relative to the regional reference, while the UK featured higher regional and national SES bias with over-representation and under-representation from the least-deprived and most-deprived quintiles (p < 0.0001).ConclusionsSignificant national differences in trial participation of low SES participants were observed, highlighting limitations in access to clinical research and the importance of reporting sociodemographic representation in diabetes clinical trials.Trial registrationNCT01581476.

Regional access to a centralized extracorporeal membrane oxygenation (ECMO) service in Victoria, Australia

IntroductionVictoria, Australia provides a centralised state ECMO service, supported by ambulance retrieval. Equity of access to this service has not been previously described. ObjectiveDescribe the characteristics of ECMO recipients and quantify geographical and socioeconomic influence on access. DesignRetrospective observational study with spatial mapping. Participants and settingAdult (≥18 years) ECMO recipients from July 2016–June 2022. Data from administrative Victorian Admissions Episodes Database analysed in conjunction with Australian Urban Research Infrastructure Network population data and choropleth mapping. Presumed ECMO modes were inferred from cardiopulmonary bypass and pre-hospital cardiac arrest codes. Spatial autoregressive models including Moran's test used for spatial lag testing. OutcomesDemographics and outcomes of ECMO recipients; ECMO incidence by patient residence (Statistical-Area Level 2, SA-2) and Index of Relative Socioeconomic Advantage and Disadvantage (IRSAD); and ECMO utilisation adjusted for patient factors and linear distance from the central ECMO referral site. Results631 adults received ECMO over 6 years, after exclusion of paediatric (n = 242), duplicate (n = 135), and interstate or incomplete (n = 72) records. Mean age was 51.8 years, and 68.8 % were male. Overall ECMO incidence was 3.00 ± 3.95 per 105 population. 135 (21.4 %) were presumed VA-ECMO, 59 (9.3 %) presumed ECPR, and 437 (69.3 %) presumed VV-ECMO. Spatial lag was non-significant after adjusting for patient characteristics. Distance from the central referral site (dy/dx = 0.19, 95% CI −0.41–0.04, p = 0.105) and IRSAD score (dy/dx = 0.17, 95% CI −0.19–0.53, p = 0.359) did not predict ECMO utilisation. ConclusionVictorian ECMO incidence rates were low. We did not find evidence of inequity of access to ECMO irrespective of regional area or socioeconomic status.
