DESCRIPTION (provided by applicant): Recognition of the comparative effectiveness of medications has profound implications for both rational and cost-effective therapeutics, but without knowing the comparative risks of medications, benefit-risk estimates are necessarily incomplete. Unique among any other treated population, risks among pregnant women relate not just to the patient (the pregnant woman), but also to the fetus. Because premarketing studies don't and can't provide meaningful risk data, this task falls to the post marketing setting. Though the debacle of thalidomide in the early 1960s identified the devastating potential of medications to cause birth defects, more than four decades later there is no system in place to comprehensively assess the pregnancy safety of even relatively commonly used medications. Asthma is the most common chronic condition requiring medication treatment in pregnancy, yet we know little about the risks to the fetus of current and newly introduced asthma medications. Using an established case control surveillance study of specific drug exposures in relation to specific birth defects (the Slone Epidemiology Center Birth Defects Study, BDS), we seek to demonstrate its ability to assess, in a systematic, efficient, and valid manner, the risks and safety of various asthma medications in relation to specific birth defects. In addition to capturing information on actual use of medications (including prescription, over-the counter, and herbals) and validating birth defects through medical record review, this study will use a validated questionnaire to assess asthma control and capture information on important confounders-such as smoking and periconceptional folate consumption-that are critical to the consideration of birth defects. Further, the project will work closely with the OTIS Pregnancy Registries and the American Academy of Asthma, Allergy, and Immunology (AAAAI) to demonstrate the feasibility and value of the Asthma and Allergy Medications in Pregnancy Safety Surveillance (AAMPSS) approach, a collaborative system involving two complementary data collection methods (BDS case-control surveillance and OTIS pregnancy registries) combined into a common infrastructure that includes an Independent Advisory Committee (to be coordinated by the AAAAI). The success of this demonstration project will lead to an ongoing, comprehensive, and valid system to assess the fetal risks associated with the wide range of medications (beyond asthma), and will permit comparative effectiveness measures to finally include critically important information on the risks and safety of medications taken by pregnant women.

描述（由申请人提供）：认识到药物的比较有效性对合理和具有成本效益的治疗具有深远的意义，但不知道药物的比较风险，收益-风险评估必然是不完整的。与其他接受治疗的人群不同，孕妇的风险不仅与患者（孕妇）有关，而且与胎儿有关。因为上市前的研究没有也不能提供有意义的风险数据，所以这项任务落到了上市后的环境中。尽管20世纪60年代早期沙利度胺的失败证明了药物可能导致出生缺陷，但40多年过去了，仍然没有一个系统来全面评估即使是相对常用的药物的妊娠安全性。哮喘是妊娠期最常见的需要药物治疗的慢性疾病，但我们对目前和新引入的哮喘药物对胎儿的风险知之甚少。通过对与特定出生缺陷相关的特定药物暴露的病例对照监测研究（斯隆流行病学中心出生缺陷研究，BDS），我们试图证明其以系统、有效和有效的方式评估与特定出生缺陷相关的各种哮喘药物的风险和安全性的能力。除了获取药物的实际使用信息（包括处方、非处方和草药）和通过医疗记录审查确认出生缺陷外，本研究还将使用一份有效的问卷来评估哮喘控制情况，并获取重要混杂因素的信息，如吸烟和孕产期叶酸摄入，这些因素对出生缺陷的考虑至关重要。此外，该项目将与奥的斯妊娠登记中心和美国哮喘、过敏和免疫学学会（AAAAI）密切合作，以证明妊娠安全监测中哮喘和过敏药物（AAMPSS）方法的可行性和价值。将两种互补的数据收集方法（BDS病例控制监测和OTIS妊娠登记）合并为一个共同基础设施的协作系统，其中包括一个独立咨询委员会（由AAAAI协调）。该示范项目的成功将导致一个持续的、全面的、有效的系统来评估与各种药物（哮喘以外）相关的胎儿风险，并将允许比较有效性的措施，最终包括孕妇所服用药物的风险和安全性的重要信息。
