Abstract
Eighth of March 2020, the Italian government introduced a national lockdown to counter the exponential increase in the number of COVID-19 cases; this decision avoided putting a strain on the health system. During the lockdown all non-essential services were stopped and a "stay at home" order was imposed. The purpose is to evaluate the impact of COVID-19 lockdown on Emergency Department (ED) visits due to work-related traumas in the Lombardy region. We performed a retrospective analysis on trauma admissions to the ED registered through the regional portal (EUOL), from 1st January 2019 to 31st December 2019 and from 1st January 2020 to 31st December 2020. The number of ED admissions for traumatic injury and work-related traumas dropped by 32% between 2019 and 2020. A remarkable reduction of work-related traumas was recorded during the two pandemic waves, from March to June and in October and November. The percentage of patient in critical condition in ED slightly raised. These results are probably a consequence of the unprecedented measures imposed by the Italian government to cope with the spread of COVID-19, with important implications for work contexts. This analysis should be considered to optimise the organisation of the emergency system in other critical scenarios. We speculate that the different epidemiology of occupational injuries during the lockdown period is a consequence of smart-working policies that can be held responsible for the drastic reduction of work-related traumas.
