Table 2.

Themes exemplifying the statements of the 14 health professionals

Themes	Statements
Personal themes	Emailing the patient is very convenient, especially during night shifts (n=7).
	I did not think about emailing the patient, I like to call patients (n=2).
Software-related themes	The software was complex (n=8).
	Patients’ email addresses were not available in the HIS at the start of the pilot, calling the patient to collect the email address was very time consuming (n=8).
	Since we used so little, I forgot how to send an email with it (n=5).
Patient-related themes	Patients did not have an email address, even not the patients of 40–50 years old (n=10).
	Patients are not ready to use the web-based questionnaires, in 10 years this will be different (n=10).
	Some patients are not interested in follow-up care, sometimes they are too sick and sometimes they already have support (n=10).
Organisation-related themes	There are no resources available for follow-up care, we arranged it in our own time (n=4).
	A follow-up consultation is not part of the ‘routine care process’, patients perceive it as optional and might not come (n = 4).
