Factors associated with completion of patient surveys 1 year after bariatric surgery

BackgroundPatient-reported outcomes (PRO) obtained from follow-up survey data are essential to understanding the longitudinal effects of bariatric surgery. However, capturing data among patients who are well beyond the recovery period of surgery remains a challenge, and little is known about what factors may influence follow-up rates for PRO.ObjectivesTo assess the effect of hospital practices and surgical outcomes on patient survey completion rates at 1 year after bariatric surgery.SettingProspective, statewide, bariatric-specific clinical registry.MethodsPatients at hospitals participating in the Michigan Bariatric Surgery Collaborative are surveyed annually to obtain information on weight loss, medication use, satisfaction, body image, and quality of life following bariatric surgery. Hospital program coordinators were surveyed in June 2017 about their practices for ensuring survey completion among their patients. Hospitals were ranked based on 1-year patient survey completion rates between 2011 and 2015. Multivariable regression analyses were used to identify associations between hospital practices, as well as 30-day outcomes, on hospital survey completion rankings.ResultsOverall, patient survey completion rates at 1 year improved from 2011 (33.9% ± 14.5%) to 2015 (51.0% ± 13.0%), although there was wide variability between hospitals (21.1% versus 77.3% in 2015). Hospitals in the bottom quartile for survey completion rates had higher adjusted rates of 30-day severe complications (2.6% versus 1.7%, respectively; P = .0481), readmissions (5.0% versus 3.9%, respectively; P = .0157), and reoperations (1.5% versus .7%, respectively; P = .0216) than those in the top quartile. While most hospital practices did not significantly impact survey completion at 1 year, physically handing out surveys during clinic visits was independently associated with higher completion rates (odds ratio, 13.60; 95% confidence interval, 1.99?93.03; P =.0078).ConclusionsHospitals vary considerably in completion rates of patient surveys at 1 year after bariatric surgery, and lower rates were associated with hospitals that had higher complication rates. Hospitals with the highest completion rates were more likely to physically hand surveys to patients during clinic visits. Given the value of PRO on longitudinal outcomes of bariatric surgery, improving data collection across multiple hospital systems is imperative.     

以患者为中心的药物研发策略

介绍美国食品及药物管理局（FDA）以患者为中心的药物开发思路,展示了不同疾病、治疗收益、使用环境分别对应的临床结局评估（COA）工具,整理出5个已获批患者报告结局（PRO）工具的相关信息,并归纳了2010—2015年FDA获批新药中,应用PRO评估工具支持说明书相关声明的药品信息。旨在为业界选择适合的COA类型（PRO、ClinRO、ObsRO或PerfO评估工具）应用于药物研发提供借鉴,并建议将COA工具用于儿科、罕见病、认知障碍相关疾病以及中药的临床疗效评估;同时也为将患者的观点纳入药品监管流程提供参考。     

腰腿痛患者报告结局量表的应用分析

目的:检验腰腿痛患者报告结局量表的信度、效度及反应度.方法:2010年8月至2012年1月,纳入住院腰椎间盘突出症及腰椎管狭窄症患者患者200例,男93例,女107例;年龄22～65岁,平均50.3岁;腰椎间盘突出症144例,腰椎管狭窄症56例 应用腰腿痛患者报告结局量表对患者进行测评,并对量表进行信度、效度、反应度分析.结果:39例病情无变化患者两次评分无显著性差异(P＞0.05),且有显著相关性(r＞0.9);该量表同Oswestry功能障碍指数问卷(ODI)对患者评分结果具有显著相关性(r＞0.8);该量表总体克朗巴赫α系数为0.931,总体Guttman折半系数为0.912;该量表KMO统计量为0.919,Bartlett球形检验卡方值l 882.975(P＜0.01),因子分析方法提取特征根值＞1的3个公因子,累计贡献率为64.364％;43例病情有好转患者两次评分结果分别为34.80±9.00和28.77±8.73,两者差异有统计学意义(P＜0.01).结论:腰腿痛患者报告结局量表有较好的信度、效度及反应度,可作为腰腿痛患者临床疗效的评价工具.     

Standards for Instrument Migration When Implementing Paper Patient-Reported Outcome Instruments Electronically: Recommendations from a Qualitative Synthesis of Cognitive Interview and Usability Studies

Objectives

To synthesize the findings of cognitive interview and usability studies performed to assess the measurement equivalence of patient-reported outcome (PRO) instruments migrated from paper to electronic formats (ePRO), and make recommendations regarding future migration validation requirements and ePRO design best practice.

血清HCG与孕酮联合检测对异位妊娠保守治疗的监测价值

目的探讨血清促绒毛膜性腺激素(HCG)与孕酮(PRO)联合检测对异位妊娠治疗方案的选择和保守治疗疗效观察的价值。方法回顾性观察我院保守治疗的250例异位妊娠患者资料进行分析,根据治疗效果分为成功组和失败组,分别为237例和13例,比较两组血清的HCG和PRO水平。结果成功组治疗前血清中的HCG与PRO水平明显低于失败组(p<0.005),治疗后4、7、14天血清中的HCG与PRO水平成功组显著低于失败组(p<0.001)。结论血清HCG与孕酮联合检测对异位妊娠治疗方案的选择和保守治疗的疗效观察是一个很好的筛选和监测指标。     

Health problems are more common,but less severe when measured using newer EQ-5D versions

ObjectivesThe EuroQol Group recently released youth (Y) and 5-level (5L) versions of its 3-level EQ-5D instrument (3L) that measures health-related quality of life. In this study, we (1) compare 3L, Y, and 5L responses among US adults and (2) assess construct validity.Study Design and SettingUsing a nationally representative sample of US adults (N = 2,619), we collected 3L, Y, and 5L responses in random order and estimated their associations and their relationship with a 0 to 100 numerical visual analog scale.ResultsThe prevalence of US adults in the best possible EQ-5D state (i.e., 11111) was lower for the Y (38%) and 5L (35%) than for the 3L (44%), capturing more health problems. However, the prevalence of extreme responses in pain/discomfort and anxiety/depression decreased substantially between the 3L and 5L (from 44% to 17% and from 29% to 13%, respectively).ConclusionCompared with the 3L, the Y and 5L versions describe population health as having more, yet milder, health problems. Although the 5L may have advantages in patient populations in which extreme problems are more prevalent, population studies or studies that follow patients from childhood may consider using the Y.
