Abstract

Introduction
Transcatheter aortic valve implantation (TAVI) is an alternative to surgical aortic valve replacement for patients with aortic stenosis. However, the choice between TAVI, surgery, wait and watch or conservative management needs to be based upon multiple factors including comorbidity, life expectancy, anatomy, local experience and, critically, informed patient preference. In this context, engaging patients in a shared decision-making (SDM) process becomes essential, but this practice is generally underused.

Purpose
To comply with both international guidance and the National Institute for Health and Care Excellence (NICE) UK recommendations, in January 2023 we established a formal SDM pathway for TAVI, utilising digital solutions as much as possible to minimise the logistic impact for both hospital and patients. We aimed to quantitatively measure the compliance of the digital SDM meeting from the patients’ perspective with the NICE recommended essential and enhanced discussion standards.

Methods
Patients are contacted when the multidisciplinary heart team recommends TAVI, then offered digital or, where appropriate, physical patient decision aids and a link to a TAVI-specific explanatory video. One week later, patients are invited to a virtual comprehensive SDM meeting where a specialist nurse discusses aortic stenosis and treatment options with the patient as per the NICE recommended standards, allowing time for questioning and review.
From December 2022 to June 2023, a custom developed questionnaire was administered to 20 patients prior to, and 28 patients after the implementation of the SDM meeting protocol, directly addressing the patients’ perception of adherence to the NICE standards. This was provided to the patients after the TAVI procedure via an online tool. The answers to the 12 core questions were converted into a Likert scale (1 to 5) and the global satisfaction scores for the 2 patient groups, reported as the average Likert score across the 12 questions, were compared with the Wilcoxon Rank-Sum Test.

Results
The global satisfaction score was significantly higher for the post-SDM group than for the pre-SDM group (mean 4.27 vs 3.55, p&lt;0.001). The percentage of patients who gave positive (Likert 4-5) responses to each individual question was consistently higher in the post-SDM group. The percentage of patients giving negative (Likert 1-2) responses was substantially lower in the post-SDM group.

Conclusions
The SDM pathway and the virtual tools provided proved effective in delivering SDM in compliance with international guidance and NICE recommended standards from the patient’s perspective. A similar approach leveraging digital technology to minimise cost and enhance patient convenience could be implemented for other treatments and across other institutions.Questionnaire results
