A web-based knowledge database to provide evidence-based information to cancer patients: Utilization within the PIKKO study.

Purpose: Cancer is associated with an urgent need for understandable and reliable information, which is often not satisfied by information available online. Therefore, as part of the PIKKO project, a web-based knowledge database (WDB) was introduced to provide cancer patients with quality-assured, evidence-based information. This paper aims to provide insights into the usage (Who? How? What?) and the effects regarding health literacy of the WDB.

Methods: A patient survey and automatically generated logfile data were evaluated. Two user groups, patients and patient navigators (PNs), were compared.

Results: The 13 PNs were responsible for 1/3 of all accesses over the entire duration of the project. The 413 patients used WDB twice on average and spent an average of 12 min per session online (PNs: 9 min per session, more frequently). The top 3 topics of interest were 'therapy', 'nutrition' and 'carcinogenesis' for the patients, and 'therapy', 'naturopathy' and 'legal regulations/support' for the PNs. Of the patients surveyed, 69% said that WDB was helpful in making informed decisions, 76% found the information they wanted and 90% thought WDB was an appropriate way to provide information.

Conclusion: Our WDB provided important information about cancer and its treatment on a digital way both, to patients and PNs. In routine cancer care, the WDB can improve health literacy and informed decision-making.
