Ethics approval and consent to participate
: The study was conducted in compliance with the Declaration of Helsinki and was reviewed by the medical ethics committee of the University Hospital Maastricht and Maastricht University (METC azM/UM) on December 19th 2014 (METC 14–5-097). In the invitation letter study participants were informed about the aims and procedures of the study, were given the choice whether to participate or not and were ensured about their anonymity. Their verbal consent was obtained in the beginning of the interviews and was recorded accordingly. (No written consent form could be obtained for all interviews due to the fact that interviews were held via telephone where printing, signing and scanning consent form would have been additional burden for participants).
: Participant’s consent for publication was given verbally before the interviews. It was also a prerequisite for partaking in the interview study and was accordingly stated in the invitations already.
: The authors declare that they have no competing interests.
