1 PROJECT SUMMARY/ABSTRACT 2 3 Every year, millions of U.S. women must decide whether to have their uteri removed to treat painful and 4 incapacitating gynecologic disorders, such as uterine fibroids, endometriosis, and prolapse. Unfortunately, 5 decisions about hysterectomy may be influenced as much by a woman's race as by objective clinical 6 indications. Despite hysterectomy's prevalence, little is known about how these surgery decisions are made: 7 the existing literature is limited by non-generalizable single-institution studies, racially homogenous samples, 8 inadequate control for symptom severity, and inability to measure the influences of the culture of the healthcare 9 system. The long-term goal of this proposal is to ensure that women of all backgrounds are treated in an 10 equitable manner when it comes to hysterectomy decision-making. To achieve this goal, the objectives of this 11 application are to understand where racial differences in treatment with gynecologic surgery arise and to 12 evaluate the extent to which racial/ethnic differences in hysterectomy treatment constitute surgical disparities. 13 The central hypothesis is that clinical severity will not fully account for all racial/ethnic differences in 14 hysterectomy treatment. We hypothesize that provider-level and practice-level clinical culture can impede 15 equitable dissemination of surgical innovations in hysterectomy. The rationale for the proposed research is that 16 identifying multilevel health care-system influences on hysterectomy receipt will help identify the best targets 17 on which to intervene to achieve equitable surgical care of women's gynecologic conditions. The hypotheses 18 will be tested by pursuing three specific aims: 1) Determine the extent to which the clinical threshold for 19 hysterectomy (uterine weight, pre-operative anemia, pre-operative pain) varies by race/ethnicity; 2) Quantify 20 the extent to which minority patients are differentially likely to be treated by low-volume providers and by 21 practices with high propensity to perform hysterectomy; and 3) Identify drivers of the dissemination of bilateral 22 salpingectomy with ovarian retention (BSOR) at the time of hysterectomy and the extent to which this 23 dissemination varied by race/ethnicity. This approach is innovative because it directly evaluates the 24 longstanding but untested hypothesis that racial differences in clinical severity explain differences in 25 hysterectomy rates. The work also employs an innovative multilevel framework including provider- and 26 practice-level factors. Finally, the work investigates how surgical culture can facilitate or impede the 27 dissemination of a cancer risk-reducing surgical innovation. This work will have sustained impact because it 28 goes beyond documenting racial differences: when this work is completed, we will understand what disparities 29 exist but also how these differences arise. Gynecologic problems are under-investigated relative to their high 30 prevalence, impact on quality of life, and long-term effects of treatment on the health of tens of millions of U.S. 31 women. Fortunately, hysterectomy is both common and amenable to change; therefore, identifying targets to 32 improve equity in the surgery can exert a powerful influence on the gynecologic surgery field. 33 1

1项目概要/摘要 2 每年，数以百万计的美国妇女必须决定是否切除子宫，以治疗疼痛和疼痛。 4失能性妇科疾病，如子宫肌瘤、子宫内膜异位症和脱垂。不幸的是， 关于子宫切除术的决定可能受到女性种族和客观临床表现的影响。 6个适应症。尽管子宫切除术的流行，很少有人知道这些手术的决定是如何作出的： 7现有文献受到不可推广的单机构研究、种族同质样本的限制， 8.对症状严重程度的控制不足，无法衡量医疗保健文化的影响 9系统。这项提案的长期目标是确保所有背景的妇女都得到平等对待， 10公平的方式，当谈到子宫切除术的决策。为了实现这一目标， 11应用是为了了解妇科手术治疗中的种族差异， 12评估子宫切除术治疗的种族/民族差异构成手术差异的程度。 [13]中心假设是临床严重程度不能完全解释所有种族/民族差异， 子宫切除术14例。我们假设，提供者层面和实践层面的临床文化可以阻碍 15子宫切除术中手术创新的公平传播。拟议研究的理由是， 确定多层次的卫生保健系统对子宫切除术的影响将有助于确定最佳目标 17对妇女的妇科状况进行干预，以实现公平的外科护理。的假设 18将通过追求三个具体目标进行测试：1）确定临床阈值的程度， 19子宫切除术（子宫重量、术前贫血、术前疼痛）因人种/种族而异; 2）量化 20少数族裔患者接受低容量提供者和低容量提供者治疗的可能性有多大差异 21种具有高倾向性的子宫切除术;和3）确定双侧子宫切除术传播的驱动因素， 22例子宫切除术时输卵管切除术伴卵巢潴留（BSOR）， 23传播因种族/族裔而异。这种方法是创新的，因为它直接评估 24个长期存在但未经检验的假设，即临床严重程度的种族差异解释了 25例子宫切除率。这项工作还采用了一个创新的多层次框架，包括供应商和 26个实践层面的因素。最后，这项工作调查如何手术文化可以促进或阻碍 27传播一种降低癌症风险的手术创新。这项工作将产生持续的影响，因为它 28超越了记录种族差异：当这项工作完成时，我们将了解什么是差异， 第29章这些差异是如何产生的妇科问题相对于他们的高 30患病率，对生活质量的影响，以及治疗对数千万美国人健康的长期影响。 31名女性幸运的是，子宫切除术既常见又易于改变;因此， 提高手术公平性对妇科手术领域具有重要影响。 33 1
