A better understanding of motivations to participate as well as recommendations to reduce barriers to enrollment may assist in design of future clinical trials.
We developed a 32-item electronic questionnaire to explore motivations, experiences, and recommendations of inflammatory bowel disease patients, who had participated in pharmaceutical clinical trials in a tertiary center in Canada over the last decade. We employed a mixed-methods approach that integrates both quantitative and qualitative research methods.
We distributed a total of 69 e-mails with surveys and received 46 responses (66.6% response rate). Study participants were mostly male (27/46, 58.7%), non-Hispanic White (43/46, 93.5%), with a mean age of 45.5 years (SD 10.9). Most decided to participate in a clinical trial to benefit future patients (29/46, 63.0%). Half of the participants (23/46, 50.0%) reported they were worried about the possibility of receiving placebo, although the majority (29/46, 63.0%) understood they could improve on placebo. The most challenging aspect reported was the number and length of questionnaires (15/46, 32.6%), as well as the number of colonoscopies (14/46, 30.4%). Strategies recommended to increase enrollment were reduction of the chance of receiving placebo (20/46, 43.5%), facilitating inclusion of patients who have failed multiple therapies (20/46, 43.5%), allowing virtual visits (18/46, 39.1%), including subtypes of disease traditionally excluded from trials (16/46, 34.8%) and improving outreach to underrepresented populations (13/46, 28.3%). The vast majority (37/46, 80.4%) reported their experience of participation to be better than expected.
These results should help inform the design of future clinical trials with a focus on patient-centricity.
更好地理解参与动机以及减少入组障碍的建议,可能有助于未来临床试验的设计。
我们设计了一份包含32个条目的电子问卷,以探究过去十年在加拿大一家三级中心参与药物临床试验的炎症性肠病患者的动机、经历和建议。我们采用了一种混合方法,将定量和定性研究方法结合起来。
我们共发送了69封附有调查问卷的电子邮件,收到46份回复(回复率66.6%)。研究参与者大多为男性(27/46,58.7%),非西班牙裔白人(43/46,93.5%),平均年龄45.5岁(标准差10.9)。大多数人决定参与临床试验是为了让未来的患者受益(29/46,63.0%)。一半的参与者(23/46,50.0%)表示担心会接受安慰剂,尽管大多数人(29/46,63.0%)明白服用安慰剂也可能改善病情。报告中最具挑战性的方面是问卷的数量和长度(15/46,32.6%),以及结肠镜检查的次数(14/46,30.4%)。建议的增加入组人数的策略包括减少接受安慰剂的几率(20/46,43.5%)、便利纳入多种治疗均失败的患者(20/46,43.5%)、允许虚拟就诊(18/46,39.1%)、纳入传统上被排除在试验之外的疾病亚型(16/46,34.8%)以及加强对代表性不足人群的宣传(13/46,28.3%)。绝大多数人(37/46,80.4%)表示他们的参与体验比预期更好。
这些结果应有助于为未来以患者为中心的临床试验设计提供参考。
