    Background: Pharmaceutical opioid analgesic use continues to rise and is associated with potentially preventable harm including hospitalisation for adverse drug reactions (ADRs). Spatial detection of opioid-related ADRs can inform future intervention strategies. We aimed to investigate the geographical disparity in hospitalised ADRs related to opioid analgesic use, and to evaluate the difference in patient characteristics between areas inside and outside the geographic clusters.This study was supported by the NHMRC CRE Medicines and Ageing Small Project Grants scheme.

    Importance: Resettled refugees in high-income countries represent a vulnerable population. It is known that refugees have high rates of trauma-related mental health issues; however, ad hoc research has generally revealed low rates of health services use among refugees. Such research usually samples a population at a single point in time and is based on targeted surveys. Because refugee populations change over time, such research becomes expensive and time-consuming for agencies interested in routinely publishing statistics of mental health services use among refugees. The linking of large administrative data sets to establish rates of use of mental health services among resettled refugees is a flexible and relatively inexpensive approach. Objective: To use data linkage to establish rates of mental health services use among resettled refugees relative to the general population. Design, Setting, and Participants: This cross-sectional study implemented data linkage from the Refugee Health Nurse Program for 10050 refugees who resettled in Sydney, Australia, from October 23, 2012, to June 8, 2017, with data concerning use of community mental health services and mental health hospitalization from New South Wales Health databases. Data were analyzed between June 1, 2019, and December 31, 2021. Main Outcomes and Measures: Rates of service contacts with community mental health services among the resettled refugees were compared with those of the general population by age, sex, and the most common International Statistical Classification of Diseases and Related Health Problems, Tenth Revision, diagnosis codes. Length of community mental health service sessions and rates of mental health hospitalizations were also compared. Results: Among the 255 resettled refugees who had contacts with community mental health care services and were not missing data (median age, 35 [range, 4-80] years; 117 [64%] male and 138 [54%] female), 153 (60%) were born in Iraq and 156 (61%) were Arabic speaking. This population was less likely to use mental health services than the general population and had shorter community mental health consultations. The rate of contacts with community mental health services for depressive disorders among the resettled refugee population was 40% (95% CI, 33%-46%) lower than that among the general population. Rates of same-day hospitalization per 10000 person-years were not significantly different between the refugee population (4 [95% CI, 2-8]) and the general Australian population (7 [95% CI, 7-7]). However, the refugee population was 17% (95% CI, 6%-29%) more likely than the general Australian population to interact with the community mental health system for severe stress- and adjustment disorder-related diagnoses. Conclusions and Relevance: These findings suggest that refugees who have resettled in Australia tend to use fewer mental health services than the general population except for services devoted to stress- and adjustment disorder-related diagnoses. These findings also suggest that it is possible to successfully leverage data linkage to study patterns of mental health services use among resettled refugees.</p

    Introduction: Public health agencies around the world are concerned about an ever-increasing burden of type 2 diabetes and related disability. Access to primary care providers (PCPs) can support early diagnosis and management. However, there is limited literature on how frequently older people with diabetes access PCPs, and their levels of access in rural Australia relative to metropolitan areas. Methods: In this research, patterns of PCP use among those with diagnosed diabetes and those without diagnosed diabetes (referred to as ‘healthy' individuals) were compared using a large survey of more than 230 000 people aged 45 years and older from New South Wales, Australia. A published model to study the PCP access patterns of a group of individuals with diabetes risk was used. Results: Annual visits to PCPs among people aged 45 years or more with diabetes in rural areas, while higher than for healthy rural residents, were significantly lower than their metropolitan counterparts, mirroring similar disparities in PCP use across the rural-urban divide in the healthy population. Similar patterns were present in the high-risk population. Nevertheless, people with diabetes visited PCPs around four times a year, which is around the recommended number of annual visits, although some groups (eg those with comorbidities) may need more visits. Conclusion: Patterns of PCP use among rural residents, while significantly less frequent than their metropolitan counterparts, are at the recommended level for people with diabetes

    OBJECTIVES: To report the baseline results of a longitudinal psychosocial study that forms part of the IMPACT study, a multi-national investigation of targeted prostate cancer (PCa) screening among men with a known pathogenic germline mutation in the BRCA1 or BRCA2 genes. PARTICPANTS AND METHODS: Men enrolled in the IMPACT study were invited to complete a questionnaire at collaborating sites prior to each annual screening visit. The questionnaire included sociodemographic characteristics and the following measures: the Hospital Anxiety and Depression Scale (HADS), Impact of Event Scale (IES), 36-item short-form health survey (SF-36), Memorial Anxiety Scale for Prostate Cancer, Cancer Worry Scale-Revised, risk perception and knowledge. The results of the baseline questionnaire are presented. RESULTS: A total of 432 men completed questionnaires: 98 and 160 had mutations in BRCA1 and BRCA2 genes, respectively, and 174 were controls (familial mutation negative). Participants' perception of PCa risk was influenced by genetic status. Knowledge levels were high and unrelated to genetic status. Mean scores for the HADS and SF-36 were within reported general population norms and mean IES scores were within normal range. IES mean intrusion and avoidance scores were significantly higher in BRCA1/BRCA2 carriers than in controls and were higher in men with increased PCa risk perception. At the multivariate level, risk perception contributed more significantly to variance in IES scores than genetic status. CONCLUSION: This is the first study to report the psychosocial profile of men with BRCA1/BRCA2 mutations undergoing PCa screening. No clinically concerning levels of general or cancer-specific distress or poor quality of life were detected in the cohort as a whole. A small subset of participants reported higher levels of distress, suggesting the need for healthcare professionals offering PCa screening to identify these risk factors and offer additional information and support to men seeking PCa screening

    Multiple novel prostate cancer susceptibility signals identified by fine-mapping of known risk loci among Europeans

    Genome-wide association studies (GWAS) have identified numerous common prostate cancer (PrCa) susceptibility loci. We have fine-mapped 64 GWAS regions known at the conclusion of the iCOGS study using large-scale genotyping and imputation in 25 723 PrCa cases and 26 274 controls of European ancestry. We detected evidence for multiple independent signals at 16 regions, 12 of which contained additional newly identified significant associations. A single signal comprising a spectrum of correlated variation was observed at 39 regions; 35 of which are now described by a novel more significantly associated lead SNP, while the originally reported variant remained as the lead SNP only in 4 regions. We also confirmed two association signals in Europeans that had been previously reported only in East-Asian GWAS. Based on statistical evidence and linkage disequilibrium (LD) structure, we have curated and narrowed down the list of the most likely candidate causal variants for each region. Functional annotation using data from ENCODE filtered for PrCa cell lines and eQTL analysis demonstrated significant enrichment for overlap with bio-features within this set. By incorporating the novel risk variants identified here alongside the refined data for existing association signals, we estimate that these loci now explain ∼38.9% of the familial relative risk of PrCa, an 8.9% improvement over the previously reported GWAS tag SNPs. This suggests that a significant fraction of the heritability of PrCa may have been hidden during the discovery phase of GWAS, in particular due to the presence of multiple independent signals within the same regio

    The use of mapping to identify priority areas for the prevention of home injuries

    Geographical information system (GIS) technology is a potentially useful tool for policy makers to identify priority areas for the prevention of injuries in the home environment. An analysis of hospitalised injuries in New South Wales (NSW), Australia, that occurred in the home environment was conducted using Bayesian methods to calculate the expected relative home injury risk for common injury mechanisms. The results show geographic differences in the mechanism of home injuries. The risk of hospitalised fall-related injuries for people aged 75 years and over and poisoning of children four years of age or less was spread over NSW, while cut/pierce and struck by/struck against injuries showed less extensive areas of risk. This study shows that the use of geographic mapping and spatial statistics can provide a useful means of estimating home injury risk, eliminating the instability of estimates, while showing overall geographic patterns. In the future, geographical mapping of injury locations, coupled with satellite imagery, are likely to provide an additional level of detail for injury surveillance within a defined area.6 page(s

    Advances in geographic information systems (GIS) and increased availability of routinely collected data have the potential to contribute to public health and health services research. The aim of this feasibility study was to explore the use of GIS to measure access to general practices and its relationship to selected antenatal behaviours. The researchers obtained the Perinatal Data Collection, 2004−2008, for South Western Sydney Local Health District from the New South Wales Ministry of Health. Using a GIS, they generated circular and polygon-based 1 km and 2 km road network buffers from a maternal residential address and then calculated the number of general practices within those buffers (density measures). Distances to general practices from maternal residences were also calculated in the GIS as another measure of geographic access to general practices (proximity measures). They used generalised estimating equations logistic regression to examine associations between access to general practices, and smoking during pregnancy and late first antenatal visit. They found that the numbers of general practices within circular buffers were significantly greater than within polygon-based road network buffers. The average distance to the five closest general practices from a mother’s residence was 2.3&nbsp;km&nbsp;±&nbsp;3.0&nbsp;km. For two of the five measures of access, a higher number of general practices was associated with increased risk for late first antenatal visit. However, the associations were weak, with odds ratios very close to unity. Choice of metrics of geographic access to general practices did not alter the associations with smoking during pregnancy or late first antenatal visit. The study showed&nbsp;that geographic information systems can be used to quantify measures of geographic access to health services for public health and health services research. Geographic access to general practices was generally not associated with smoking during pregnancy or late first antenatal visit. The&nbsp;researchers concluded that&nbsp;GIS and routinely collected health data can be used to answer novel questions in public health and health services research

    Background: Walkability scores have been developed to measure how well the characteristics of the physical environment support walking. However, because pedestrian safety is not taken into account, areas that have higher Walk Scores could be associated with more walking and also more pedestrian-related injury. We aimed to explore the association between Walk Score and pedestrian-related injury in Sydney. Method: Pedestrian-related injuries from 2010 to 2018 in Sydney were identified in the New South Wales Combined Admitted Patient Epidemiology Data. Walk Score was used to measure area-level walkability in Sydney statistical division. Regression models were used to examine the association between Walk Score, pedestrian-related injury, length of hospital stay (LOS) and injury severity. Result: Among people aged ≤64 years, there was no significant association between walkability score and pedestrian-related injury. Among people aged ≥ 65 years, walkability score was significantly positively associated with pedestrian-related injury, which peaked at Somewhat Walkable. For most disadvantaged areas, the risk of pedestrian-related injury was highest for areas that were classified as Somewhat Walkable. For moderately disadvantaged areas, the risk of pedestrian-related injury was highest at Very Walkable to Walker's Paradise areas. For the least disadvantaged areas, there was no significant association between walkability score and pedestrian-related injury. For LOS among people aged ≥ 65 years or in the most disadvantaged areas, it peaked at Somewhat Walkable areas. For injury severity, the risk of serious pedestrian-related injury was highest at Very Walkable to Walker's Paradise areas among people aged 16–64 years. Conclusion: For the majority of the population, built environment characteristics that are considered to make walking attractive also make it safer, offsetting any exposure-related increase injury risk. However, this is not the case for people aged ≥ 19 years, and those living in socioeconomically disadvantaged areas. Incorporating measures of pedestrian safety in walkability scores may create an impetus to ensure that the built environment is designed to support the safety of pedestrians from these groups.</p
