Capture-Recapture Estimates of Workplace Injury Rates

描述（由申请人提供）：本研究将使用两个最广泛和最全面的非致命工伤和疾病报告来源来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工统计局每年进行的职业伤害和疾病调查。它还将提供俄勒冈州、华盛顿州、威斯康星州、新墨西哥州、佛罗里达州、德克萨斯州、明尼苏达州和西弗吉尼亚州8个州职业伤害和疾病总年发病率的改进估计。此外，它将开发和评估匹配来自多个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这些特征对报告率的影响。在1998-2000年期间，该研究将通过匹配8个州的个人伤害和疾病来比较这两种来源的伤害报告。它将制定方法来匹配这两个来源的数据，并估计错误匹配的记录的比例。然后，它将对每个州进行捕获-再捕获分析，以改进非致命伤害发生率的测量方法。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漏报有关的因素。然后，我们将比较这两个数据系统在所研究的州捕获职业伤害和疾病的程度。该研究将对每个研究州的工伤发生率和漏报率提供改进的估计，这些工伤涉及离开工作的天数，并向州工人赔偿系统报告。对于8个州中的4个州，估计将包括至少一天的工伤。对于所有8个州，这项研究将产生至少8天休假的伤害的可比估计。如果根据协变量，捕获率在各州之间是一致的，那么从所研究的州估计的捕获率将应用于研究人口以外的州，以提供对伤害和疾病发生率的改进的全国估计。

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.
