 DESCRIPTION (provided by applicant): Approximately 2 million women (-1% of all women) in the United States may have an undiagnosed bleeding disorder, yet many of these disorders remain undetected for years or are never diagnosed. Women with bleeding disorders are at increased risk for heavy menstrual bleeding, iron deficiency anemia, antepartum bleeding, postpartum hemorrhage, and may undergo unnecessary hysterectomy and other uterine surgeries that can lead to additional complications. A common bleeding disorder in women is von Willebrand disease (VWD), defined as a quantitative or qualitative deficiency of von Willebrand factor. To decrease the frequency and morbidity of complications from undiagnosed VWD, expert guidelines recommend screening for VWD in adolescents with heavy menses and prior to any hysterectomy for heavy menses. For pregnant women with diagnosed VWD, third trimester monitoring of VWF is recommended to best plan for a safe labor and delivery and reduce the risk of postpartum hemorrhage. Although VWD is a common disease, with an estimated prevalence of 1.6 million American women, past research in this area has been primarily limited to single institution settings or patient registries derived from hemophilia treatment centers. Women with milder disease or limited access to treatment centers are therefore underrepresented. Our long-term goal is to perform research that aids in decreasing the frequency and morbidity of reproductive bleeding in women with underlying bleeding disorders. Utilizing administrative claims data to study bleeding complications in women with VWD will provide our team unique access to a large and diverse population of women diagnosed with VWD, including those with mild disease. In the proposed study we will utilize the ClinformaticsDataMart, a longitudinal health care database representing >45 million covered lives (including >7,000 reproductive-aged women with VWD), to investigate the quality of reproductive health care in women with VWD during the time period of 2000-2013. The specific aims of our proposal are to: 1) investigate the impact of distance to hemophilia treatment centers and other patient and facility characteristics on the frequency of VWD screening in adolescents with heavy menses and women undergoing hysterectomy for excessive bleeding, and 2) identify the population-based frequency and timing of postpartum hemorrhage, and compare the frequency of postpartum hemorrhage in women with VWD or do and do not undergo third trimester VWF monitoring. Identifying gaps in reproductive care in women with diagnosed VWD and those at risk for VWD will allow for targeted educational and advocacy efforts, and improved implementation of interventions to mitigate the consequences of VWD in reproductive-age women and eliminate barriers to high­ quality care. Our research seeks to identify barriers to implementation of the NHLBI's and other expert guidelines regarding the evaluation and management of VWD, and supports the Healthy People 2020 goal to increase the proportion of women with VWD who receive a timely and accurate diagnosis.

 描述（由申请人提供）：美国大约有 200 万女性（占所有女性的-1%）可能患有未确诊的出血性疾病，但其中许多疾病多年来未被发现或从未被诊断。患有出血性疾病的女性出现月经过多、缺铁性贫血、产前出血、产后出血的风险增加，并且可能会接受不必要的子宫切除术和其他子宫手术，从而导致其他并发症。女性常见的出血性疾病是冯·维勒布兰德病 (VWD)，定义为冯·维勒布兰德因子的定量或定性缺陷。为了降低未确诊 VWD 并发症的发生频率和发病率，专家指南建议对月经量多的青少年以及在月经量多进行子宫切除术之前进行 VWD 筛查。对于诊断为 VWD 的孕妇，建议在妊娠晚期进行 VWF 监测，以便为安全分娩和分娩做好最佳计划，并降低产后出血的风险。尽管 VWD 是一种常见疾病，估计有 160 万美国女性患病，但过去该领域的研究主要限于单一机构环境或源自血友病治疗中心的患者登记。因此，患有较轻疾病或进入治疗中心的机会有限的妇女所占比例不足。我们的长期目标是进行研究，帮助降低患有潜在出血性疾病的女性生殖出血的频率和发病率。利用行政索赔数据来研究患有 VWD 的女性的出血并发症，将为我们的团队提供独特的途径来接触大量且多样化的被诊断患有 VWD 的女性，包括患有轻度疾病的女性。在拟议的研究中，我们将利用 ClinformaticsDataMart（一个涵盖超过 4500 万人（包括超过 7000 名患有 VWD 的育龄妇女）的纵向医疗保健数据库）来调查 2000 年至 2013 年期间患有 VWD 的妇女的生殖保健质量。我们提案的具体目的是：1) 调查血友病治疗中心的距离以及其他患者和设施特征对月经量多的青少年和因出血过多而接受子宫切除术的妇女进行 VWD 筛查频率的影响，2) 确定基于人群的产后出血频率和时间，并比较患有 VWD 或接受和未接受第三次子宫切除术的妇女的产后出血频率。 妊娠期 VWF 监测。确定诊断为 VWD 的妇女和有 VWD 风险的妇女在生殖保健方面的差距，将有助于开展有针对性的教育和宣传工作，并改进干预措施的实施，以减轻 VWD 对育龄妇女的影响，并消除获得高质量护理的障碍。我们的研究旨在找出实施 NHLBI 和其他有关 VWD 评估和管理的专家指南的障碍，并支持“健康人民 2020”目标，即增加获得及时、准确诊断的 VWD 女性比例。
