项目摘要
7. PROJECT SUMMARY
Over 15 million Americans now have severe obesity, i.e. a body-mass index (BMI) ≥35 kg/m2. Patients with
severe obesity have 5-times higher prevalence of type 2 diabetes, and twice the annual medical costs of those
with normal body weights. Bariatric surgery is the most effective treatment for severe obesity, but is invasive,
costly, and associated with short and longer-term complications. The vertical sleeve gastrectomy (VSG) is a
newer bariatric procedure that has substantially increased in use recently, now accounting for approximately
half of procedures worldwide. However, very little is known about longer-term outcomes after VSG, including
the durability of its impact on diabetes, and its potential for reducing cardiovascular morbidity and mortality. Of
particular importance for patients considering surgery, the risks and benefits of VSG compared to the “gold
standard” gastric bypass (RYGB) procedure are not well understood. The proposed study will use a nationwide
commercial insurance claims dataset to evaluate clinical and health care use outcomes among over 10,000
patients undergoing VSG, compared to 10,000 patients undergoing RYGB, between 2005 and 2017, with up to
8 years of post-operative follow-up. Rigorous observational study designs with propensity-score matching will
be used to compare the effect of VSG and RYGB on: clinical outcomes, including diabetes remission and
relapse, myocardial infarction, stroke and death; health care use outcomes including emergency department
visits, hospital days, and reoperation or revisional surgery; and health care costs including standardized total,
prescription and out-of-pocket costs. Furthermore, to assist with procedure selection, exploratory analyses will
investigate the optimal surgical type for patients with certain key characteristics (e.g. by age group, diabetes
severity). To minimize risk of confounding by indication, cutting-edge propensity-score matching algorithms will
be employed and rigorous longitudinal designs such as interrupted time series and survival analysis will be
constructed. This will be the largest claims-based comparative study of these two procedures, with potential to
significantly impact clinical practice in bariatric surgery. Findings could inform more evidence-based practice
and facilitate shared clinical decision-making by improving the ability of patients and surgeons to select a
surgical approach that is optimized to patients’ preferred health outcomes and personal characteristics.
7.项目摘要
超过1500万美国人现在患有严重肥胖症,即体重指数(BMI)≥35 kg/m2。患者
严重肥胖的人患2型糖尿病的患病率是严重肥胖的人的5倍,
体重正常的人减肥手术是治疗严重肥胖症最有效的方法,但具有侵入性,
成本高,并伴有短期和长期并发症。垂直袖状胃切除术(VSG)是一种
新的减肥手术,最近使用大幅增加,现在约占
全世界一半的手术然而,对VSG后的长期结果知之甚少,包括
其对糖尿病影响的持久性,以及其降低心血管发病率和死亡率的潜力。的
特别重要的是,对于考虑手术的患者,与“黄金”相比,
标准”胃旁路术(RYGB)程序还不太清楚。这项研究将使用一个全国性的
商业保险索赔数据集,以评估超过10,000名患者的临床和医疗保健使用结果
2005年至2017年间,接受VSG的患者与接受RYGB的10,000例患者相比,
术后随访8年。具有倾向评分匹配的严格观察性研究设计将
用于比较VSG和RYGB对临床结局的影响,包括糖尿病缓解和
复发、心肌梗死、卒中和死亡;医疗保健使用结局,包括急诊
访视、住院天数和再次手术或翻修手术;以及医疗保健费用,包括标准化总额,
处方和自付费用。此外,为了帮助程序选择,探索性分析将
调查具有某些关键特征(例如,按年龄组、糖尿病)的患者的最佳手术类型
严重性)。为了最大限度地减少适应症的混杂风险,尖端的倾向评分匹配算法将
将采用严格的纵向设计,如中断时间序列和生存分析,
构建了这将是对这两种程序进行的最大规模的基于索赔的比较研究,
显著影响减肥手术临床实践。研究结果可以为更多的循证实践提供信息
并通过提高患者和外科医生选择治疗方案的能力,
根据患者偏好的健康结果和个人特征进行优化的手术方法。
