Ethics, risks, side effects, and inconvenience
POSTOPERATIVE COMPLICATIONS
All participants were included after informed consent and could withdraw their consent and decide to make their data deleted at any time without further explanation and with no impact on the treatment and care in the department. The Scientific Ethical Committee (VEK-number H-21018467) in Denmark and the local hospital-based IRB approved the pilot and the final project before starting.Inclusion in the project involved few and low risks, mainly originating from the collection and storage of sensitive data for patients, which was lowered even further by carefully following the guidelines for each procedure. In addition, changing lifestyle behaviours could be temporarily uncomfortable for patients, but the possible effect might balance this over time of reduced postoperative complications and better health.The participants had access to a hotline (e-mail or phone) for the clinical project staff during the weekday. The participants were free to use other healthcare services to support smoking and alcohol cessation.
