Immediate and long-term health impact of exposure to gas-mining induced earthquakes and related environmental stressors

BACKGROUND: Little is known about the public health impact of chronic exposure to physical and social stressors in the human environment. Objective of this study was to investigate the immediate and long-term health effects of living in an environment with gas-mining induced earthquakes and related stressors in the Netherlands. METHODS: Data on psychological, somatic and social problems recorded routinely in electronic health records by general practitioners during a 6-year period (2010–2015) were combined with socioeconomic status and seismicity data. To assess immediate health effects of exposure to M(L)≥1.5 earthquakes, relative risk ratios were calculated for patients in the week of an earthquake and the week afterwards, and compared to the week before the earthquake. To analyse long-term health effects, relative risks of different groups, adjusted for age, sex and socioeconomic status, were computed per year and compared. RESULTS: Apart from an increase in suicidality, few immediate health changes were found in an earthquake week or week afterwards. Generally, the prevalence of health problems was higher in the mining province in the first years, but dropped to levels equal to or even below the control group in subsequent years, with lower relative risks observed in more frequently exposed patients. CONCLUSIONS: From a public health perspective, the findings are fascinating. Contrary to our expectation, health problems presented in general practice in the earthquake province decreased during the study period. More frequently exposed populations reported fewer health issues to general practitioners, which might point at health adaptation to chronic exposure to stressors

Cost-effectiveness of installing barriers at bridge and cliff sites for suicide prevention in Australia

Importance: Installation of barriers has been shown to reduce suicides. To our knowledge, no studies have evaluated the cost-effectiveness of installing barriers at multiple bridge and cliff sites where suicides are known to occur. Objective: To examine the cost-effectiveness of installing barriers at bridge and cliff sites throughout Australia. Design, Setting, and Participants: This economic evaluation used an economic model to examine the costs, costs saved, and reductions in suicides if barriers were installed across identified bridge and cliff sites over 5 and 10 years. Specific and accessible bridge and cliff sites across Australia that reported 2 or more suicides over a 5-year period were identified for analysis. A partial societal perspective (including intervention costs and monetary value associated with preventing suicide deaths) was adopted in the development of the model. Interventions: Barriers installed at bridge and cliff sites. Main Outcomes and Measures: Primary outcome was return on investment (ROI) comparing cost savings with intervention costs. Secondary outcomes included incremental cost-effectiveness ratio (ICER), comprising the difference in costs between installation of barriers and no installation of barriers divided by the difference in reduction of suicide cases. Uncertainty and sensitivity analyses were undertaken to examine the association of changes in suicide rates with barrier installation, adjustments to the value of statistical life, and changes in maintenance costs of barriers. Results: A total of 7 bridges and 19 cliff sites were included in the model. If barriers were installed at bridge sites, an estimated US $145 million (95$90 to $160 million) could be saved in prevented suicides over 5 years, and US$270 million (95% UI, $176 to$298 million) over 10 years. The estimated ROI ratio for building barriers over 10 years at bridges was 2.4 (95% UI, 1.5 to 2.7); the results for cliff sites were not significant (ROI, 2.0; 95% UI, -1.1 to 3.8). The ICER indicated monetary savings due to averted suicides over the intervention cost for bridges, although evidence for similar savings was not significant for cliffs. Results were robust in all sensitivity analyses except when the value of statistical life-year over 5 or 10 years only was used. Conclusions and Relevance: In an economic analysis, barriers were a cost-effective suicide prevention intervention at bridge sites. Further research is required for cliff sites

Global burden of 288 causes of death and life expectancy decomposition in 204 countries and territories and 811 subnational locations, 1990–2021: a systematic analysis for the Global Burden of Disease Study 2021

BACKGROUND Regular, detailed reporting on population health by underlying cause of death is fundamental for public health decision making. Cause-specific estimates of mortality and the subsequent effects on life expectancy worldwide are valuable metrics to gauge progress in reducing mortality rates. These estimates are particularly important following large-scale mortality spikes, such as the COVID-19 pandemic. When systematically analysed, mortality rates and life expectancy allow comparisons of the consequences of causes of death globally and over time, providing a nuanced understanding of the effect of these causes on global populations. METHODS The Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2021 cause-of-death analysis estimated mortality and years of life lost (YLLs) from 288 causes of death by age-sex-location-year in 204 countries and territories and 811 subnational locations for each year from 1990 until 2021. The analysis used 56 604 data sources, including data from vital registration and verbal autopsy as well as surveys, censuses, surveillance systems, and cancer registries, among others. As with previous GBD rounds, cause-specific death rates for most causes were estimated using the Cause of Death Ensemble model-a modelling tool developed for GBD to assess the out-of-sample predictive validity of different statistical models and covariate permutations and combine those results to produce cause-specific mortality estimates-with alternative strategies adapted to model causes with insufficient data, substantial changes in reporting over the study period, or unusual epidemiology. YLLs were computed as the product of the number of deaths for each cause-age-sex-location-year and the standard life expectancy at each age. As part of the modelling process, uncertainty intervals (UIs) were generated using the 2·5th and 97·5th percentiles from a 1000-draw distribution for each metric. We decomposed life expectancy by cause of death, location, and year to show cause-specific effects on life expectancy from 1990 to 2021. We also used the coefficient of variation and the fraction of population affected by 90% of deaths to highlight concentrations of mortality. Findings are reported in counts and age-standardised rates. Methodological improvements for cause-of-death estimates in GBD 2021 include the expansion of under-5-years age group to include four new age groups, enhanced methods to account for stochastic variation of sparse data, and the inclusion of COVID-19 and other pandemic-related mortality-which includes excess mortality associated with the pandemic, excluding COVID-19, lower respiratory infections, measles, malaria, and pertussis. For this analysis, 199 new country-years of vital registration cause-of-death data, 5 country-years of surveillance data, 21 country-years of verbal autopsy data, and 94 country-years of other data types were added to those used in previous GBD rounds. FINDINGS The leading causes of age-standardised deaths globally were the same in 2019 as they were in 1990; in descending order, these were, ischaemic heart disease, stroke, chronic obstructive pulmonary disease, and lower respiratory infections. In 2021, however, COVID-19 replaced stroke as the second-leading age-standardised cause of death, with 94·0 deaths (95% UI 89·2-100·0) per 100 000 population. The COVID-19 pandemic shifted the rankings of the leading five causes, lowering stroke to the third-leading and chronic obstructive pulmonary disease to the fourth-leading position. In 2021, the highest age-standardised death rates from COVID-19 occurred in sub-Saharan Africa (271·0 deaths [250·1-290·7] per 100 000 population) and Latin America and the Caribbean (195·4 deaths [182·1-211·4] per 100 000 population). The lowest age-standardised death rates from COVID-19 were in the high-income super-region (48·1 deaths [47·4-48·8] per 100 000 population) and southeast Asia, east Asia, and Oceania (23·2 deaths [16·3-37·2] per 100 000 population). Globally, life expectancy steadily improved between 1990 and 2019 for 18 of the 22 investigated causes. Decomposition of global and regional life expectancy showed the positive effect that reductions in deaths from enteric infections, lower respiratory infections, stroke, and neonatal deaths, among others have contributed to improved survival over the study period. However, a net reduction of 1·6 years occurred in global life expectancy between 2019 and 2021, primarily due to increased death rates from COVID-19 and other pandemic-related mortality. Life expectancy was highly variable between super-regions over the study period, with southeast Asia, east Asia, and Oceania gaining 8·3 years (6·7-9·9) overall, while having the smallest reduction in life expectancy due to COVID-19 (0·4 years). The largest reduction in life expectancy due to COVID-19 occurred in Latin America and the Caribbean (3·6 years). Additionally, 53 of the 288 causes of death were highly concentrated in locations with less than 50% of the global population as of 2021, and these causes of death became progressively more concentrated since 1990, when only 44 causes showed this pattern. The concentration phenomenon is discussed heuristically with respect to enteric and lower respiratory infections, malaria, HIV/AIDS, neonatal disorders, tuberculosis, and measles. INTERPRETATION Long-standing gains in life expectancy and reductions in many of the leading causes of death have been disrupted by the COVID-19 pandemic, the adverse effects of which were spread unevenly among populations. Despite the pandemic, there has been continued progress in combatting several notable causes of death, leading to improved global life expectancy over the study period. Each of the seven GBD super-regions showed an overall improvement from 1990 and 2021, obscuring the negative effect in the years of the pandemic. Additionally, our findings regarding regional variation in causes of death driving increases in life expectancy hold clear policy utility. Analyses of shifting mortality trends reveal that several causes, once widespread globally, are now increasingly concentrated geographically. These changes in mortality concentration, alongside further investigation of changing risks, interventions, and relevant policy, present an important opportunity to deepen our understanding of mortality-reduction strategies. Examining patterns in mortality concentration might reveal areas where successful public health interventions have been implemented. Translating these successes to locations where certain causes of death remain entrenched can inform policies that work to improve life expectancy for people everywhere.

Reducing the Future Risk of Trauma: On the Integration of Global Disaster Policy within Specific Health Domains and Established Fields of Practice

The global increase in the frequency and severity of natural hazards and extreme climatic events necessitates more efficient global and national strategies to reduce the likelihood and impact of traumatic consequences for disaster-affected populations. The recent inclusion of mental health in the Sendai Framework for Disaster Risk Reduction marks a pivotal point in the recognition of the significant burden of disasters on mental health, and a global commitment to reducing its impacts. Nevertheless, effective agreement implementation and efforts to reduce disaster mental health risks are facing significant challenges. These include a lack of clarity about the conceptual interlinkages and place of disaster risk reduction principles within the field of disaster mental health, which is traditionally marked by a prevailing recovery orientation, and the need for effective translation into disaster mental health policy and practice. Therefore, this study drew on data from interviews with European disaster mental health and risk reduction experts in order to appraise the merit and implications of a global disaster risk reduction policy for advancing population mental health in the context of disaster. Study findings outline existing opportunities, challenges, and key strategies for the integration of disaster risk reduction within disaster mental health policy and practice

Research Priorities in Suicide Prevention: Review of Australian Research from 2010–2017 Highlights Continued Need for Intervention Research

Suicide is a major public health concern in Australia and globally, requiring targeted research efforts to build the evidence base for its effective prevention. We examined current and future priorities in Australian suicide prevention research during the period 2010–2017, and compared these to 1999–2006 baseline data. We classified current research priorities in terms of the type of research published in 424 journal articles and 36 grants and fellowships funded during 2010–2017. A questionnaire administered to 390 stakeholders identified future research priorities. The total number of suicide prevention focussed journal articles and the value of funded grants increased dramatically. Congruent with baseline data, current research priorities in 2010–2017 reflected a strong emphasis on epidemiological studies, while funding for intervention studies declined. This is despite the fact that stakeholders continually identified intervention studies as being the highest future research priority. If we are to make real advances in suicide prevention, we need to know what works, and identify and test effective interventions. This study highlighted the existing dearth and continued need for intervention research. Mechanisms to support future intervention research in suicide prevention are likely to lead to significant gains in knowledge and population health

Examining Victoria’s disaster mental health capacity: towards systematic disaster mental health workforce and service planning

© 2013 Dr. Lennart ReifelsNatural disasters increasingly impact on the Victorian population, resulting in greater calls on mental health services and providers of psychosocial support. However, little is known about Victoria’s capacity to respond to the mental health consequences of major natural disasters. It is therefore timely to examine key indicators of Victoria’s disaster mental health service and workforce capacity and to examine the strengths and limitations of current approaches to building such capacity in view of future natural disasters. To this end, the current thesis examined key indicators of, and current approaches to building, Victoria’s disaster mental health service and workforce capacity in the context of the response to Australia’s largest bushfire disaster, the Victorian Black Saturday Bushfires. Through a series of four studies, this thesis investigated strengths and limitations of novel service delivery models and capacity building approaches, and the profile and capacity of the Victorian disaster mental health workforce. Study findings will inform a more strategic approach to disaster mental health workforce and service planning, sustainable capacity building and enhanced provision of best practice mental health support to disaster-affected Victorians in the future

Disaster Mental Health Risk Reduction: Appraising Disaster Mental Health Research as If Risk Mattered

Since disaster risk reduction requires efforts from multiple disciplines, it is obvious that knowledge development should not be limited to single disciplines either and address concepts such as disaster risk, hazards, exposure, vulnerability, and capacity jointly. This line of reasoning applies to the mental health dimension of disaster risk reduction as well. Yet, an assessment of “disaster mental health risk reduction” (DMHRR) research con-tributions, learns that the emphasis of authors is typically limited to a selection of these concepts. Similarly selective is the focus on different levels (primarily individual and community), Sendai Priority Actions (mostly “understanding disaster risk”, followed by “enhancing disaster preparedness”) and Health EDRM functions (especially “information and knowledge management” and “monitoring and evaluation”). Placing the concept of disaster risk at the heart of DMHRR research, enables us to bring together the different facets of research contributions and to generate a combined, arguably even integrated view on disaster risk reduction and mental health. The DMHRR road ahead is complex, all-encompassing and therefore challenging. Fortunately, important progress is made in understanding the mental health impact of disaster exposure, additional losses and the interplay with risk factors that increase vulnerabilities at different levels across countries and regions, linked to the capacity to adapt, recover, and ultimately reduce such risks. A complementary common ground of evidence-based knowledge to shape and direct this capacity is embedded in available guidelines and policy documents, partially translated into practical training programs with promising first results. This is all in-dicative of the improvement made in recent years, as work in progress to be continued, that can assist and encourage stakeholders from policy, practice, and research internationally to keep joining forces on behalf of a successful integration of mental health and psychosocial support into disaster risk reduction
