Experiences and outcomes of patients participating in a perioperative shared decision-making pathway.

The Complex Decision Pathway (CDP) is a novel perioperative shared decision-making pathway that was established in the Bay of Plenty, New Zealand in 2018. Unique features of the pathway include the use of a structured communication tool to facilitate a goals-of-care conversation in addition to medical assessment, and the use of a tikanga Māori framework for Māori patients. From May 2019 until May 2022, 81 patients attending the CDP clinic were recruited to a prospective study of their demographics, health status and experience at the time of presentation, along with outcomes and opinions over the subsequent 12 months. Participants were mostly elderly and frail with multiple comorbidities, and just over half of participants chose to undergo surgery. Participants who chose, or were recommended, not to undergo surgery were older, more comorbid and had worse outcomes over the subsequent 12 months. Qualitative data suggested an overall positive patient experience of the pathway, and an economic analysis demonstrated its cost-effectiveness. Overall, the data presented here suggested that the CDP assisted in risk-stratifying patients into operative and non-operative groups, provided a positive patient experience, and was a cost-effective intervention.
