Ethics approval and consent to participate
: Written informed consent was obtained from all interviewees; all interviews were conducted in Geneva, either in-person or over the phone. Written informed consent for remote interviews was obtained via email prior to conducting the interview; interviewees then kept a signed copy for their records and WHO kept a copy securely stored together with all other signed informed consent forms from in-person interviews. A legend was included in the survey stating that response to the survey implied consent to participate. All participants involved were offered the option to recuse themselves at any time during the study. All tools used for global primary data collection were submitted to WHO’s Ethics Review Committee (ERC) and received approval (Protocol ID: A65787). The protocol approved by ERC was for a multi-site, multi-country project which included the names of all participating countries.
