Are regulations effective in reducing construction injuries? An analysis of the Italian context

Abstract

Objectives At the end of the 1990s, as required by European Directive 92/57/EEC, two laws were enacted in Italy which laid down safety and health requirements for construction sites: Decree 494/96 and Decree 528/99. The aim is to evaluate the impact on injury rates due to actions performed by a group of eight regions that planned formalised programmes to enforce the laws around the year 2000. Methods Using the Work History Italian Panel-Salute integrated database, which extends from 1994 to 2005, total and serious injury rates were calculated for the construction sector. An interrupted time series analysis was applied to serious injury rates. Results During the 12 years under observation, at the national level the total and serious injury rates decreased while the number of employees increased. The results of the regression models indicate that in the period after the intervention the injury rates (×10 000 weeks worked) decreased by 0.21 per year more than in the period before the intervention (CI −0.41 to −0.01). The difference in pre-post trends is even larger after adjusting for external factors. Conclusions The intervention plans developed to enforce the two Italian decrees had an effect on the reduction in injury rates. The results showed that there was a decrease in injury rates that could not be explained by external factors. These findings highlight the importance of concrete initiatives to have employers and workers comply with regulatory safety standards.

Prevention of falls to a lower level: evaluation of an occupational health and safety intervention via subsidies for the replacement of scaffolding

“…Other studies [27,39] have confirmed that compliance with certain new legal provisions significantly reduces the number of work accidents. In particular, in 2006, a new regulation on subcontracting in the construction sector was introduced in Spain.…”

“…[36] Although previous studies showed evidence of the effectiveness of other interventions, [27,36,37,38,39,40] this is the first available analysis of the effectiveness of renewing the scaffolds in construction enterprises in order to incorporate standardized ones.…”

“…Recently, the effect of regulations in reducing construction injuries has been also analyzed. [27] By means of autoregressive analyses, Yassin et al, [28] examined the efficiency of a compulsory provision concerning scaffold safety standards in the construction industry in the USA. According to their analysis, 4.6 fatal accidents, 404 non-fatal accidents and 2,896 workday losses per year were prevented.…”

Public injury prevention system in the Italian manufacturing sector: What types of inspection are more effective?

“…In Italy, research focused on effectiveness evaluation of work inspection is scarce [Farina et al, ]. In 2009, the Ministry of Health financed a study to evaluate the impact of targeted inspections for injury prevention in manufacturing industries.…”

Evaluation of occupational health interventions using a randomized controlled trial: challenges and alternative research designs

“…Farina and colleagues investigated the impact of national legislation on minimum safety and health requirements in 1999 on injuries at construction sites (56). Total and serious injury rates in the construction sector were calculated from 1994-2005, based on an integrated database (ie, Work History Italian Panel Salute).…”
