Multifaceted implementation strategy for implementing Oncokompas

1	Readiness and possible barriers and facilitators were identified in a previous feasibility study and assessment of HCP perspectives [6, 11].
2	The Oncokompas team presented Oncokompas to the HCPs involved in oncology care (often centralized in an oncological committee, which is an executive medical board), highlighting the participatory design approach, features of Oncokompas, benefits for patients and HCPs, and ease of use of the application. In case a hospital adopted Oncokompas, an instructional meeting was organized for staff that was going to work with Oncokompas. In case Oncokompas was not adopted, any subsequent requests of individual HCPs of these hospitals to implement Oncokompas individually were referred to the HCPs/oncological committee who decided not (yet) to adopt Oncokompas.
3	Instructional meeting: more in-depth information about Oncokompas as well as an explanation on how to offer Oncokompas to patients.
4	HCPs were provided with educational materials on Oncokompas: a script containing general information about Oncokompas, goals of the implementation, manuals on working with Oncokompas, screenshots of Oncokompas, and a frequently asked questions section (for patients and HCPs). A public website was also available with relevant information.
5	HCPs received promotional business cards of Oncokompas to hand out to patients.
6	Support and technical assistance for HCPs and patients were centralized and available through a helpdesk, operated by the Dutch Federation of Cancer Patient Societies.
7	Via the health insurance company, full reimbursement for all cancer survivors was assured. A prerequisite for reimbursement was that Oncokompas was to be offered by the HCP.
8	Progress in implementation was closely monitored and stimulated through an implementation advisory committee.
