The epidemiological profile and morbidity-mortality patterns of technological disasters in Europe from 2000 to 2021

OBJECTIVE

To analyse the epidemiological profile of technological disasters that occurred in Europe between 2000 and 2021, focusing on morbidity and mortality rates, as well as temporal trends.

STUDY DESIGN

A retrospective descriptive analysis was conducted using data from EM-DAT, DesInventar, NatCAt, and Sigma.

METHODS

The disasters were classified into transport, industrial, and miscellaneous accidents. Statistical analyses were conducted to examine the frequencies, trends, and correlations among types of disasters. The Mann-Kendall test was used to determine the presence or absence of temporal trends, while the Augmented Dickey-Fuller test was used to check for stationarity in the time series. Exponential smoothing was used to forecast the annual number of technological disasters up to the year 2032.

RESULTS

A total of 505 technological disasters were recorded. Out of the total number of accidents, 332 (65.74 %) were transport accidents, 66 (13.07 %) were industrial accidents, and 107 (21.19 %) were miscellaneous accidents. The study found a statistically significant decreasing trend for all technological disasters (tau = -0.649; p < 0.000).

CONCLUSIONS

The total number of technological disasters and each of their types decreased. However, there were no discernible trends in the average mortality rate, the average rate of affected people, or the average rate of injuries per year.

The epidemiological profile and morbidity-mortality patterns of technological disasters in the Americas from 2000 to 2021: a cross-sectional study

Technological disasters in the Americas have significant public health and environmental implications, but there is limited epidemiological analysis of these events. This study aims to characterize the epidemiological profile of technological disasters in the Americas from 2000 to 2021, focusing on morbidity and mortality trends. A retrospective cross-sectional study was conducted. The ANOVA test was applied in the mean rates calculated for each type of disaster. The Mann-Kendall test assessed the presence or absence of temporal trends, and the Dickey-Fuller augmented test was used to determine if the time series were stationary. Predictions were made up to the year 2030 to mean mortality rate per million inhabitants, mean rate of people affected per million inhabitants, and mean rate of people injured per million inhabitants. A total of 733 technological disasters were recorded in the Americas. Statistically significant differences were found between the mean rates of people affected and the mean mortality rates per million inhabitants for each type of technological disaster. No trends were identified. The highest mean mortality rates occurred because of industrial accidents.

Technological disasters in Asia: Epidemiological profile from the year 2000 to 2021

BACKGROUND

Technological disasters in Asia have significant public health and environmental implications, but there is limited epidemiological analysis of these events. This study aims to characterize the epidemiological profile of technological disasters in Asia from 2000 to 2021, focusing on morbidity and mortality trends.

METHODS

A retrospective descriptive observational analysis was conducted using data from emergency events database (EM-DAT), DesInventar, NatCAt, and Sigma. The study categorized disasters into transport, industrial, and miscellaneous accidents. Statistical analyses were used to examine frequencies, trends, and correlations among the different disaster types.

RESULTS

From 2000 to 2021, Asia experienced 2333 technological disasters, with transport accidents being the most frequent (55.77%), followed by industrial (26.10%) and miscellaneous accidents (18.13%). The overall trend showed a statistically significant decrease in the frequency of these disasters and in average mortality and injury rates. The study highlighted the varying impact of different disaster types, with industrial accidents causing the highest fatality and affected rates despite being less frequent than transport accidents.

CONCLUSIONS

The study indicates a declining trend in the frequency and severity of technological disasters in Asia, reflecting improved safety measures and disaster management. However, the high impact of industrial accidents underscores the need for targeted prevention strategies.
