Tailoring information to older colorectal cancer patients: Effects of using a web-based patient-directed tool

Interventions: Patients will be assigned to an experimental condition that receives the Patient Navigator in addition to usual care or to a control condition that receives usual care. Randomization takes place at hospital level, i.e. three hospitals will implement the Patient Navigator and three hospitals will serve as control condition hospitals and will implement the Patient Navigator after the study has finished. The Patient Navigator is a website for older colorectal cancer patients that is systematically developed in the first part of the OCA-2 study. The Patient Navigator offers tailored information about diagnostic tests, treatments and follow-up facilities (i.e., only content that is relevant for the specific patient is showed). Moreover, the Patient Navigator offers the possibility to upload audiotaped consultations and contains tools to help patients preparing for consultations (so called Question Prompt Lists; one with general questions that people can ask about every treatment, and 13 about specific tests or treatments).
Primary outcome(s): Recall of information
Study Design: Non-randomized controlled trial, Single blinded (masking used), Active, Parallel

干预措施：受试者将被分为两组，试验组接受患者导航员（Patient Navigator）联合常规诊疗护理，对照组仅接受常规诊疗护理。本研究采用医院水平随机化分组方案：3家医院将试点启用患者导航员，剩余3家医院作为对照医院，并将于本研究结束后启动患者导航员项目。患者导航员是一款面向老年结直肠癌患者的辅助网站，于OCA-2研究的第一阶段完成系统性开发。该网站可为患者提供定制化的诊断检查、治疗方案及随访机构相关信息，即仅展示与特定患者病情匹配的内容。此外，该网站支持上传会诊录音文件，并配备辅助患者筹备会诊的工具——问题提示清单（Question Prompt List）：其中1份涵盖适用于各类治疗的通用提问条目，另有13份针对特定检查或治疗的专用提问条目。
主要结局指标：信息回忆
研究设计：非随机对照试验，单盲（采用设盲措施），主动对照，平行组设计
