Prioritising mental health in the perioperative period: understanding postoperative patterns in anxiety and depression through ecological momentary assessment.

A recent study in the British Journal of Anaesthesia examining trajectories of anxiety and depressive symptoms after diverse surgical procedures sheds light on an often overlooked, yet important, factor in postoperative recovery-mental health. The authors applied ecological momentary assessment to collect high-resolution data to identify and characterise a subgroup of vulnerable patients who experience worsening of psychological symptoms after surgery. The study prompts not only consideration of psychological factors, but also how best to leverage ecological momentary assessment to understand the perioperative experience.
