BACKGROUND & OBJECTIVES: The construction industry is a leading contributor to occupational injuries. First Information Reports (FIRs) of Indian Police are a potential data source for construction injuries. The aim of this study was to estimate the completeness of ascertainment of construction site injuries by FIRs.
This was a two-sample capture-recapture study of construction site injuries sustained in the year 2017 in Delhi, India. The first capture sample was data extracted from FIRs. The second capture sample comprised data extracted from the Employee State Insurance Corporation (ESIC) and the Commissioners of Workmen Compensation. The Chapman estimator was used to estimate, with 95% confidence intervals, the total numbers of fatal and non-fatal injuries.
FIRs ascertained 374 injuries (110 fatal and 264 non-fatal) while the combined data of ESIC and workmen compensation claims ascertained 80 injuries (48 fatal and 32 non-fatal). The capture-recapture analysis estimated that 1,011 (95% CI: 873 to 1149) injuries: 258 (95% CI: 221 to 295) fatal injuries and 873 (95% CI: 765 to 1053) non-fatal injuries were sustained in Delhi in 2017.
INTERPRETATION & CONCLUSIONS: FIRs ascertain approximately one-third of all construction site injuries. In the absence of any other data source, FIRs may be used as the basis of a construction injury surveillance system, recognizing that any estimates made using these data must be adjusted to allow for the approximately two-thirds of injuries not reported to the police. Further research is needed to identify reasons for some injuries not being reported to the police, in order to help to develop a strategy to improve the completeness of ascertainment of construction site injuries for the future.
建筑业是职业伤害的主要贡献者。印度警方的首次信息报告（FIR）是建筑伤害的潜在数据源。本研究的目的是评估通过FIR确定建筑工地伤害的完整性。
这是一项对2017年印度德里建筑工地受伤情况进行的两样本捕获-再捕获研究。第一个捕获样本是从FIR中提取的数据。第二个捕获样本包括从雇员国家保险公司（ESIC）和工人赔偿专员处提取的数据。采用查普曼估计器估计致命和非致命伤害的总数，并给出95%置信区间。
FIR确定了374起伤害（110起致命和264起非致命），而ESIC和工人赔偿索赔的综合数据确定了80起伤害（48起致命和32起非致命）。捕获-再捕获分析估计，2017年德里有1011起（95%置信区间：873至1149）伤害：258起（95%置信区间：221至295）致命伤害和873起（95%置信区间：765至1053）非致命伤害。
FIR确定了所有建筑工地伤害的约三分之一。在没有任何其他数据源的情况下，FIR可作为建筑伤害监测系统的基础，但要认识到使用这些数据进行的任何估计都必须进行调整，以考虑到约三分之二未向警方报告的伤害。需要进一步研究确定一些伤害未向警方报告的原因，以便制定战略，提高未来建筑工地伤害确定的完整性。
