Aim: Questionnaires are an invaluable resource for clinical trials. They serve to estimate disease burden and clinical parameters associated with a particular study. However, current researchers are tackling budget constraints, loss of funding opportunities, and rise of research associated fees. We aimed at exploring alternative avenues taking advantage of the free Google docs software for questionnaire administration. This presents an opportunity to reduce costs while simultaneously increasing efficiency and data fidelity.

Material and methods: Google documents were used as a platform to create online questionnaires that were automatically hosted via a unique URL. Password protected access to the URL link and a unique study ID gave patients around the clock access from anywhere in the world. Unique study ID ensured confidentially of all self-reported data. Patient responses were secured using a "Cloud" database where the data was automatically sorted, scaled and scored by custom Excel formulas. Researchers downloaded real-time questionnaire responses in multiple formats (e.g. excel) which was then analyzed with a statistical software of choice.

Results: This simple workflow provided instant questionnaire scores that eliminated the use for paper-based responses and subsequent manual entry of data. Ease of access to online questionnaires provided convenience to patients leading to better response rates and increase in data fidelity. The system also allowed for real time monitoring of patient's progress on completing questionnaires. Online questionnaires had 100% completion rate compared to paper-based questionnaires.

Conclusions: Google docs can serve as an efficient and free platform to administer questionnaires to a clinical population without sacrificing quality, security, and fidelity of data.

目的:调查问卷是临床试验的宝贵资源。它们用于估计与特定研究相关的疾病负担和临床参数。然而,目前的研究人员正在解决预算限制、失去资助机会以及研究相关费用上涨的问题。我们的目标是探索利用免费的谷歌文档软件进行问卷管理的替代途径。这为降低成本,同时提高效率和数据保真度提供了机会。材料和方法:使用Google文档作为创建在线问卷的平台,这些问卷通过唯一的URL自动托管。密码保护访问URL链接和唯一的研究ID,使患者可以从世界任何地方全天候访问。唯一的研究ID确保所有自我报告数据的机密性。使用“云”数据库保护患者的回答,其中数据通过自定义Excel公式自动排序,缩放和评分。研究人员下载了多种格式(如excel)的实时问卷回答,然后用所选的统计软件进行分析。结果:这个简单的工作流程提供了即时的问卷评分,消除了使用基于纸张的回答和随后的手动输入数据。易于获取的在线问卷为患者提供了便利,从而提高了应答率和数据保真度。该系统还允许实时监控患者完成问卷的进度。与纸质问卷相比,在线问卷的完成率为100%。结论:Google docs可以作为一个有效和免费的平台,在不牺牲数据质量、安全性和保真度的情况下,向临床人群管理问卷。
