Designing a Perioperative Mind-Body Intervention for Peripheral Vascular Interventions.

Background: Peripheral vascular interventions (PVIs) performed under procedural sedation and analgesia (PSA) can be associated with anxiety and poor compliance with patient instructions during surgery. Mind-body interventions (MBIs) such as meditation have demonstrated the potential to decrease perioperative anxiety, though this area is understudied, and no tailored interventions have been developed for the vascular surgical patient population.

Objectives: We aimed to design a perioperative MBI that specifically targeted vascular surgical patients undergoing PVIs under PSA. We sought to perform this in a scientifically rigorous, multi-disciplinary collaborative manner.

Methods: Following the Obesity-Related Behavioral Intervention Trials (ORBIT) model, we designed (Phase 1a) and then refined (Phase 1b) a MBI for patients undergoing PVIs under PSA to decrease perioperative anxiety and sedation and facilitate patient intraoperative compliance. Phase 1a involved a literature review, informal information gathering and synthesis, and drafting a preliminary protocol for a perioperative MBI. Phase 1b involved assembling a multi-disciplinary expert panel of perioperative and mind-body clinicians and researchers to improve the MBI using an iterative, modified Delphi approach.

Results: The modified Delphi process was completed, and a consensus was reached after three iterations. The resulting MBI consisted of two seven-minute preoperative guided meditations on the day of surgery, including diaphragmatic breathing, body scans, and guided imagery emphasizing awareness of the ipsilateral leg where the vascular surgery was performed. A document delineating the integration of the MBI into the operating room workflow was produced, including details regarding the intervention's timing, duration, and modality.

Conclusion: Using a multi-specialty expert panel, we designed a novel MBI in the form of a guided meditation with elements of mindfulness and guided imagery to decrease anxiety and increase intraoperative compliance for patients undergoing PVIs under PSA. A prospective pilot study is being planned to test the program's feasibility.
