Implementation of shared decision-making for aortic stenosis: Development of a patient decision aid

Type of funding sources: None.

 People living with aortic stenosis (AS) experience poor quality of life (QOL), repeat hospitalizations, and a poor prognosis in the absence of valve replacement. There is increasing equipoise in the evidence supporting the use of surgical aortic valve replacement (SAVR) and transcatheter aortic valve implantation (TAVI) in patients likely to derive survival and QOL benefit. A transition to a palliative approach may be a better option in the setting of excessive frailty and comorbid burden. Shared decision-making (SDM) is a bidirectional exchange between patients and health care providers that enables an information exchange about the best available evidence and decisions that consider patients" priorities. The goal is to inform and empower patients to participate in choosing the right decision. Patient decision aids (PDAs) are designed to support the process of SDM and help guide these conversation. To date, Canadians living with AS have not had access to a validated PDA. 

  We will report on the design of the SharEd DEcision-MaKing for AS (SEEK-AS) study that aims to refine and comprehensively evaluate a set of PDAs and to build capacity for SDM through a unique partnership of patient and clinical knowledge users, multidisciplinary health care providers and researchers, and policy-makers. We will summarize the pilot work completed to obtain a debrief of patient resources used in all Canadian provinces, the draft development of a PDA in concert with a health policy initiative, and the design of an electronic platform to individualize risk in real time during a consultation. We will outline the components of SEEK-AS and the use of a cross-provincial comparative case study design to investigate how to establish an effective and sustainable approach for the implementation of the PDAs using the Knowledge-to-Action conceptual framework. 

 There is a pressing need for the development of evidence-based tools to strengthen the integration of patients" perspectives in the treatment of complex valvular heart disease given the rapid pace of change in technology, indications and practice. The study of the implementation of innovative strategies to achieve this goal is essential to accelerate the pace of change in clinical care.
