Analysis of the regional distribution of road traffic mortality and associated factors in Japan

Ambulance Traffic Crashes in Japan: Characteristics of Casualties and Efforts to Improve Ambulance Safety

BACKGROUND

An ambulance traffic crash not only leads to injuries among emergency medical service (EMS) professionals but also injures patients or their companions during transportation. We aimed to describe the incidence of ambulance crashes, seating location, seatbelt use for casualties (ie, both fatal and nonfatal injuries), ambulance safety efforts, and to identify factors affecting the number of ambulance crashes in Japan.

METHODS

We conducted a nationwide survey of all fire departments in Japan. The survey queried each fire department about the number of ambulance crashes between January 1, 2017, and December 31, 2019, the number of casualties, their locations, and seatbelt usage. Additionally, the survey collected information on fire department characteristics, including the number of ambulance dispatches, and their safety efforts including emergency vehicle operation training and seatbelt policies. We used regression methods including a zero-inflated negative binomial model to identify factors associated with the number of crashes.

RESULTS

Among the 726 fire departments in Japan, 553 (76.2%) responded to the survey, reporting a total of 11,901,210 ambulance dispatches with 1,659 ambulance crashes (13.9 for every 100,000 ambulance dispatches) that resulted in a total of 130 casualties during the 3-year study period (1.1 in every 100,000 dispatches). Among the rear cabin occupants, seatbelt use was limited for both EMS professionals (n = 3/29, 10.3%) and patients/companions (n = 3/26, 11.5%). Only 46.7% of the fire departments had an internal policy regarding seatbelt use. About three-fourths of fire departments (76.3%) conducted emergency vehicle operation training internally. The output of the regression model revealed that fire departments that conduct internal emergency vehicle operation training had fewer ambulance crashes compared to those that do not (odds of being an excessive zero -2.20, 95% CI: -3.6 to -0.8).

CONCLUSION

Two-thirds of fire departments experienced at least one crash during the study period. The majority of rear cabin occupants who were injured in ambulance crashes were not wearing a seatbelt. Although efforts to ascertain seatbelt compliance were limited, Japanese fire departments have attempted a variety of methods to reduce ambulance crashes including internal emergency vehicle operation training, which was associated with fewer ambulance crashes.

[Social inequalities related to road traffic mortality]

OBJECTIVE

To synthesize the social inequalities related to mortality from traffic accidents reported in scientific publications.

METHOD

A scoping review following the PRISMA-ScR guide was carried out. Using the MesH vocabulary, we systematically searched for articles in English, Portuguese and Spanish published in the EBSCO, Scielo, Scopus, Ovid, and PubMed databases.

RESULTS

We identified 47,790 records in the initial search, of which 35 articles met the selection criteria. Nine out ten publications are in high-income countries; there is a greater interest in analyzing mortality in occupants and drivers of vehicles and motorcyclists. Half of the publications use race-ethnicity and geolocation as socioeconomic position variables. The articles included in this review indicate that groups of people with low socioeconomic positions have higher mortality due to traffic accidents.

CONCLUSIONS

The highest mortality from traffic accidents occurs in people with low socioeconomic positions which suggests the development of road safety actions from a comprehensive, integrative perspective and linked to other political agendas to reduce their incidence by 2030. Although road traffic fatalities are higher in low and middle-income countries, few publications are available in these countries. It is necessary to strengthen the research capacities in these countries.

Factors Affecting Employees Work Engagement in Small and Medium-Sized Enterprises

BACKGROUND

Improving the labor productivity of small and medium-sized enterprises (SMEs) is essential because of the aging population and predicted reduction in the labor force. Therefore, it is necessary to ensure that employees are in good health to work for long times. In this regard, the purpose of the study is to investigate the relationship between work engagement (WE) and related variables among SME employees.

METHODS

A cross-sectional study was conducted using the baseline data of the prospective cohort study, which included 377 employees from three SMEs headquartered in Hiroshima Prefecture, Japan.

RESULTS

A multiple regression analysis was performed to see the associations between Utrecht Work Engagement Scale (UWES) scores and other variables. Significant associations were found with job satisfaction, age, health literacy (HL), and quality of sleep (all, p < 0.05). Additionally, there was a statistically significant difference observed in WE, quality of sleep, concern for own body, job satisfaction, and family life satisfaction (all, p < 0.001) with respect to high and low HL levels.

CONCLUSIONS

The results of this study reveal that while implementing health and productivity management in SMEs to increase WE, it is best to concentrate on raising HL, job satisfaction, and sleep quality. To increase generalizability, further research could be conducted with more SMEs companies.
