Days Alive And Out Of Hospital A Validated Patient-Centred Outcome To Be Used For Patients Undergoing Transoral Robotic Surgery: Protocol And Perspectives

BackgroundDays Alive and Out of Hospital (DAOH) has been validated as a suitable clinical trial outcome. It can be used as a proxy for surgical quality and reflects both procedure specific morbidity and mortality.Aims/objectivesWe propose DAOH as a supplement to established patient-related and objective outcomes, since it adds information on health care burden. Two upcoming studies incorporating DAOH are planned and will report DAOH for patients undergoing transoral robotic surgery.MethodsFirstly, a multicentre national prospective cohort study investigating DAOH with a 1-year follow-up after TORS is planned. Secondly a retrospective study of DAOH with a 1-year follow-up period will be performed using our institute's, the largest TORS center in Scandinavia, transoral robotic surgery (TORS) database. The database consists of more than 250 patients with more than 300 procedures performed between 2013 and 2018.Conclusion and significanceThe planned studies of DAOH may, when applied to TORS, contribute to a better interpretation of post-treatment morbidity and provide a basis for further interventional studies to enhance recovery, perioperative optimization, and serve as a comparison tool between treatment modalities.
