This research aims to identify, as early as the preoperative phase, groups of patients likely to experience maximum clinical improvement through structured paramedical follow-up based on PROMs. However, the high heterogeneity of the included patients could have masked more pronounced effects in certain subgroups, particularly those at higher risk. Relying on a multicenter approach and a subgroup analysis, our study hypothesizes that certain patient profiles are more likely to significantly benefit from personalized follow-up based on PROMs. The objective is to validate the hypothesis that support through PROMs for patients in complex situations could allow for a more pronounced clinical effect. This follow-up will enable better targeting of interventions from the preoperative phase, optimize the use of healthcare resources, and improve quality, safety, and efficiency of perioperative pathways.
