Summary of major findings per deliverable.

Deliverable	Projectsa	Conclusion
2	24	A Dutch nationwide web-based expertise center for eHealth was established, containing an eHealth toolkit with the various delivered products and the acquired knowledge [25].
3	4, 13, 15, 16, 20, and 21	Various projects published their results in national and international (scientific) journals [26-33]. In addition, an e-book has been published [34].
4	5, 9, 10, 13, 19, 23, 24, and 26	In general, the patients were enthusiastic about accessing their medical data on the web and downloading them. Physicians were still holding back. eHealth literacy must be considered in the development and implementation of eHealth. One of the university hospitals dealt with information exchange between the primary care and the hospital, for which a legal framework had been set.
5	5, 13, 19, 23, and 25	It was not always possible to implement the Dutch set of standards for interoperability. Integrating different ITb systems for exchanging data was complex and might not be desirable in a pilot phase.
6	14, 19, 23, 25, and 26	An important insight obtained was that when exchanging data, the skills of the end user should be considered. Attention should also be paid to patients with low eHealth skills.
7	5, 16, 18, 23, 24, and 29	Within the projects, there was frequent co-operation with IT developers in the region and the first- and second-line health care institutions.
8	1, 4, 5, 6, 7, 10, 13, 14, 15, 16, 17, 18, 22, 24, 25, 26, 27, 28, and 29	Most of the projects (19/29, 66%) contributed to models that strengthen the patients’ directing role. For example, 2 e-learnings were developed, in which both the patient and the caregiver received the tools to make better decisions together. In addition, several mobile apps or web-based applications that were developed, for example a medical dashboard, a patient coach, an app for glycemic index, a web-based blog and forum for patients with Alzheimer, and a home-based blood pressure monitor for high-risk pregnant women, reinforced the patients’ directing role.
9	15, 16, 18, 19, and 28	Several projects focused on establishing alternative communication infrastructures between a hospital and a patient outside the hospital. In addition, for the development of these new type of eHealth solutions, the projects required close co-operation and consultation with researchers, patients, informal caregivers, IT services, and lawyers.
10	1, 2, 3, 4, 6, 7, 8, 11, 13, 14, 15, 16, 17, 20, 21, 24, 26, 27, 28, and 29	A website with a forum and a blog was developed for patients with Alzheimer. Also, a total of 8 mobile apps were developed. Various wearables were tested for the home monitoring of patients. A clinical data science eBook was made, and several e-learnings were developed. The efficacy and effectiveness of the various eHealth solutions were scientifically evaluated.
11	3, 8, 12, 14, 15, 17, 21, 24, and 27	Several projects contributed to improving eHealth education. For example, the develop your own eHealth app project developed an education module in which medical students learned about eHealth and the necessary eHealth skills. Another project translated the English language Apple Research Kit into a Dutch variant and offered researchers a guide on how to conduct eHealth research with the kit. Finally, some projects also focused on patient education and how to enable patients with low health skills to work with eHealth tools.
