Capture-Recapture Estimates of Workplace Injury Rates

描述（由申请人提供）：本研究将使用非致命性职业伤害和疾病报告的两个最广泛和最全面的来源，以评估报告的完整性和影响差异报告的因素。这些来源是国家工人的赔偿数据和劳动统计局每年进行的职业伤害和疾病调查。它还将提供8个州的职业伤害和疾病的总体年度发生率的改进估计：俄勒冈州、华盛顿、威斯康星州、新墨西哥州、佛罗里达、得克萨斯州、明尼苏达州和西弗吉尼亚州。此外，它将制定和评价匹配多种来源的职业伤害和疾病数据的方法。最后，它将应用捕获-再捕获分析，捕获率因个人、雇主和伤害特征而异。这将使我们能够确定报告率如何因这些特征而不同。在1998-2000年期间，这项研究将通过将8个州的个人受伤和疾病相匹配，对这两个来源报告的受伤情况进行比较。它将制定方法，以匹配来自两个来源的数据，并估计错误匹配的记录比例。然后，它将使用捕获-再捕获分析，为这些国家制定改进的措施，非致命性伤害的发生率。该研究将使用逻辑回归来解释雇主，伤害和工人特征的差异捕获。这也将使我们能够确定与报告不足有关的因素。然后，我们将比较两个数据系统在所研究的州中捕获职业伤害和疾病的程度。该研究将提供每个研究州的发生率和漏报率的改进估计，这些伤害涉及离开工作的日子，并报告给州工人的赔偿制度。对于8个州中的4个州，估计数将涵盖至少一天休假的所有伤害。对于所有8个州，该研究将产生涉及至少8天休假的伤害的可比估计。如果根据协变量，各州的捕获率是一致的，则从研究的州估计的捕获率将应用于研究人群以外的州，以提供对伤害和疾病发生率的改进的国家估计。

DESCRIPTION (provided by applicant): This study will use the two most widespread and comprehensive sources of nonfatal occupational injury and illness reporting to evaluate the completeness of reporting and factors that affect differential reporting. These sources are state workers' compensation data and the Survey of Occupational Injuries and Illnesses conducted annually by the Bureau of Labor Statistics. It also will provide improved estimates of the overall annual incidence of occupational injuries and illnesses for 8 states: Oregon, Washington, Wisconsin, New Mexico, Florida, Texas, Minnesota, and West Virginia. In addition, it will develop and evaluate methods for matching occupational injury and illness data from multiple sources. Finally, it will apply capture-recapture analysis with capture rates that vary by individual, employer, and injury characteristics. This will allow us to determine how reporting rates differ by these characteristics. For 1998-2000, the study will compare reported injuries from these two sources by matching individual injuries and illnesses in 8 states. It will develop methods for matching data from the two sources and for estimating the proportion of records falsely matched. It then will use capture-recapture analysis for each of these states to develop improved measures of nonfatal injury incidence. The study will use logistic regression to account for differential capture by employer, injury, and worker characteristics. This also will enable us to identify factors associated with underreporting. Then, we will compare the degree to which the two data systems appear to capture occupational injuries and illnesses in the states studied. The study will provide improved estimates of incidence and underreporting in each study state for injuries that involve days away from work and which are reported to state workers' compensation systems. For 4 of the 8 states, the estimates will cover all injuries involving at least one day off work. For all 8 states, the study will generate comparable estimates for injuries involving at least 8 days off work. If, contingent on covariates, capture is uniform across states, capture rates estimated from the studied states will be applied to states outside the study population to provide improved national estimates of the incidence of injuries and illnesses.
