[Reassessment of burden of occupational fatal injuries in Italy, 1951-2017]. / Rivalutazione del carico di danni dovuti agli infortuni mortali sul lavoro in Italia, 1951-2017.

BACKGROUND: occupational injuries in Italy are registered primarily by the Italian National Institute for insurance against accidents at work (Inail); its statistics show the number of events by consequence type (temporary, permanent, fatal). Data prior to 2001 include fatalities only if benefits were paid to survivors entitled to compensation, typically spouse and/or children. OBJECTIVES: to estimate the number of fatal injuries occurred to workers without survivors entitled to compensation, not considered in INAIL statistics for the period 1951-2000; to evaluate years lived with disability (YLD) years of life lost (YLL), disability-adjusted life years (DALY) caused by all occupational injuries occurred in Italy, period 1951-2016. DESIGN: evaluation of the stability of the ratio among fatal accidents with and without survivors, along the period of observation (2001-2017); retrospective application of such ratio to data related to the period 1951-2000; linkage of individual injury data to Global Burden of Disease injury categories and calculation of corresponding YLLs, YLDs, DALYs; calculation of mean values by main type of consequences (temporary, permanent, fatal); application of above means to Italian data 1951-2017. SETTING AND PARTICIPANTS: occupational injuries compensated by Inail in Italy, 1951-2017. MAIN OUTCOME MEASURES: number of injuries, YLDs, YLLs, DALYs. RESULTS: fatal occupational injuries, not considered in official statistics for the period 1951-2000, are estimated to be 26,218 cases, corresponding to 1.4 millions of YLLs. In the same period, total occupational injuries (with temporary, permanent or fatal consequences) correspond to 11.5 millions of DALYs, fatal component corresponded to 5.1 millions of YLLs. CONCLUSIONS: Estimated total number of fatal occupational injuries in 1951-2000 is 28% higher than official Inail data. Considering YLLs, such increase rises up to 37%. Such difference reflects younger mean age and consequent longer life expectancy of workers without survivors. Considering DALYs, the increase is 14%. Throughout the period 1951-2017, a progressive reduction of the burden of injury is observed. At the same time a qualitative change is observed, with reduction from 55% to 30% of YLL/DALY ratio.

Reduction of excavation face collapse risk in tunnelling.

Two large road tunnels, recently developed near Florence, showed instabilities of the excavation face which subsequently caused sixteen collapses. Due to the risk for workers' safety, the public authority for occupational health and safety (ASL) has monitored the failure rate and other background variables in order to assess the possible correlations between risk reductions, its own actions, and those of the various safety actors involved. OBJECTIVES: To evaluate if the interventions carried out by the design team were able to reduce the risks of collapse and which of the ASL actions and/or which other factors were more effective in changing the attitudes of the parties involved, leading to a more expensive but safer project variant. RESULTS: After adoption of the second of two project variants, no more collapses were observed. No correlation was found between trend of ASL inspections and observed variation of collapse rate. Conversely, the adoption of strongly coercive measures and investigation reporting by local media coincided with periods of risk reduction, even if the low number of events does not allow for statistical evaluation. CONCLUSIONS: These findings appear to be coherent with the ratio of the cost of penalties related to health and safety infringements (thousands of euros) to the overall cost of the safer project variant (a hundred times greater).  The safer variant required 7% more labour but avoided forced interruptions caused by the collapses, allowing a 13% faster excavation rate.

Development of a Prototype Observatory of Heat-Related Occupational Illnesses and Injuries through the Collection of Information from the Italian Press, as Part of the WORKLIMATE Project.

Exposure to heat is a recognized occupational risk factor. Deaths and accidents at work caused by high temperatures are underestimated. With the aim of detecting and monitoring heat-related illnesses and injuries, a prototype database of occupational events attributable to critical thermal conditions reported in Italian newspapers was created. Information was analyzed from national and local online newspapers using a web application. The analysis was conducted from May to September during the three-year period 2020-2022. Articles concerning 35 occupational heat-related illnesses and injuries were selected; 57.1% of the events were reported in 2022, and 31.4% of total accidents occurred in the month of July 2022, when the Universal Thermal Climate Index daily mean values corresponded to "moderate heat stress" (51.0%) and "strong heat stress" (49.0%). Fatal heat-related illnesses were the most frequent conditions described. In most cases, workers had been involved in outdoor activities in the construction sector. A comprehensive report was created by compiling all relevant newspaper articles to enhance awareness of this issue among relevant stakeholders and promote heat-risk prevention strategies in the current context where heatwaves are becoming increasingly frequent, intense and long-lasting.

Occupational heat stress, heat-related effects and the related social and economic loss: a scoping literature review.

Introduction: While there is consistent evidence on the effects of heat on workers' health and safety, the evidence on the resulting social and economic impacts is still limited. A scoping literature review was carried out to update the knowledge about social and economic impacts related to workplace heat exposure. Methods: The literature search was conducted in two bibliographic databases (Web of Science and PubMed), to select publications from 2010 to April 2022. Results: A total of 89 studies were included in the qualitative synthesis (32 field studies, 8 studies estimating healthcare-related costs, and 49 economic studies). Overall, consistent evidence of the socioeconomic impacts of heat exposure in the workplace emerges. Actual productivity losses at the global level are nearly 10% and are expected to increase up to 30-40% under the worst climate change scenario by the end of the century. Vulnerable regions are mainly low-latitude and low- and middle-income countries with a greater proportion of outdoor workers but include also areas from developed countries such as southern Europe. The most affected sectors are agriculture and construction. There is limited evidence regarding the role of cooling measures and changes in the work/rest schedule in mitigating heat-related productivity loss. Conclusion: The available evidence highlights the need for strengthening prevention efforts to enhance workers' awareness and resilience toward occupational heat exposure, particularly in low- and middle-income countries but also in some areas of developed countries where an increase in frequency and intensity of heat waves is expected under future climate change scenarios.

The burden of injury in Central, Eastern, and Western European sub-region: a systematic analysis from the Global Burden of Disease 2019 Study.

BACKGROUND: Injury remains a major concern to public health in the European region. Previous iterations of the Global Burden of Disease (GBD) study showed wide variation in injury death and disability adjusted life year (DALY) rates across Europe, indicating injury inequality gaps between sub-regions and countries. The objectives of this study were to: 1) compare GBD 2019 estimates on injury mortality and DALYs across European sub-regions and countries by cause-of-injury category and sex; 2) examine changes in injury DALY rates over a 20 year-period by cause-of-injury category, sub-region and country; and 3) assess inequalities in injury mortality and DALY rates across the countries. METHODS: We performed a secondary database descriptive study using the GBD 2019 results on injuries in 44 European countries from 2000 to 2019. Inequality in DALY rates between these countries was assessed by calculating the DALY rate ratio between the highest-ranking country and lowest-ranking country in each year. RESULTS: In 2019, in Eastern Europe 80 [95% uncertainty interval (UI): 71 to 89] people per 100,000 died from injuries; twice as high compared to Central Europe (38 injury deaths per 100,000; 95% UI 34 to 42) and three times as high compared to Western Europe (27 injury deaths per 100,000; 95%UI 25 to 28). The injury DALY rates showed less pronounced differences between Eastern (5129 DALYs per 100,000; 95% UI: 4547 to 5864), Central (2940 DALYs per 100,000; 95% UI: 2452 to 3546) and Western Europe (1782 DALYs per 100,000; 95% UI: 1523 to 2115). Injury DALY rate was lowest in Italy (1489 DALYs per 100,000) and highest in Ukraine (5553 DALYs per 100,000). The difference in injury DALY rates by country was larger for males compared to females. The DALY rate ratio was highest in 2005, with DALY rate in the lowest-ranking country (Russian Federation) 6.0 times higher compared to the highest-ranking country (Malta). After 2005, the DALY rate ratio between the lowest- and the highest-ranking country gradually decreased to 3.7 in 2019. CONCLUSIONS: Injury mortality and DALY rates were highest in Eastern Europe and lowest in Western Europe, although differences in injury DALY rates declined rapidly, particularly in the past decade. The injury DALY rate ratio of highest- and lowest-ranking country declined from 2005 onwards, indicating declining inequalities in injuries between European countries.

[Comparison between two different Disability Weights calculations: the case of occupational injuries]. / Confronto fra due metodologie di calcolo dei pesi di disabilità: l'esempio degli infortuni sul lavoro.

AIM: To introduce the concept of DALYs (Disability Adjusted Life Years), in order to calculate the burden of occupational injuries and to compare the disability weights methodology applied by the National Institute for Insurance against Accidents at Work (INAIL) to occupational injuries, with respect to the methodology adopted by the World Health Organization in the Global Burden of Disease Study (GBD), in order to facilitate, on a regional-national basis, the future application of estimates of Burden of Disease due to this phenomenon, based on data available from the NHS. DESIGN: In the first part of the present study, a comparison between the theoretical GBD methodology, based on Disability Weights, and the INAIL methodology based on Gradi di inabilità (Degree of Disability) (GI) described in the table of impairments is made, using data on occupational injuries occurred in Tuscany from 2001 to 2008. Given the different criteria adopted by WHO and INAIL for the classification of injuries sequelae, in the second part, two equations described in the literature have been applied in order to correct systematic biases. RESULTS: In the INAIL dataset, all types of injuries, though often small in scale, have cases with permanent consequences, some of them serious.This contrasts with the assumptions of the WHO, that, apart from the cases of amputation, reduces the possibility of lifelong disabilities to a few very serious categories. In the case of femur and skull fractures, the proportion of lifelong cases is considered by WHO similar to the proportion that in the INAIL dataset is achieved after narrowing the threshold of permanent damage to cases with GI ≥ 33. In the case of amputations and spinal cord injuries, for which the WHO assumes a priori that all cases have lifelong consequences, on the contrary, the greater similarity between the assumptions and the empirically observable reality is obtained after extending the threshold of permanent damage to all cases with even minimal sequelae.The comparison between the WHO DW and INAIL GI, possible only in relation to injuries resulting in permanent damage, shows that in case of injuries of greater severity, INAIL GI are generally lower than the WHO DW. In the case of less serious injuries, INAIL gives instead higher values. The length of temporary disabilities recorded by INAIL is systematically higher than that estimated by WHO. CONCLUSIONS: These initial comparisons between the WHO methodology and the cases evaluation performed by INAIL show that the Italian system, based on the gathering of all relevant aspects related to each case, has the potential to utilize and synthesize a greater amount of information.However, wide limits of uncertainty still remain and further empirical findings are needed in order to compare the two systems in terms of precise determination of the DW, the length of disabilities and variations of mortality related to injuries.
