Patient-Centered Approach for Treatment Decisions in Mitral Valve Prolapse (PRIMARY SDM)

Prior qualitative research in decision-making related to heart valve disease has occurred largely in transcatheter aortic valve replacement (TAVR). Among patients undergoing TAVR, physicians estimate patients' symptoms and functional status poorly both before and after treatment. Prior studies have shown that significant variability exists in outcomes most important to patients versus those most important to providers. Specifically, providers may place greater emphasis on clinical endpoints such as mortality or echocardiographic improvement in valve function whereas patients often place greater emphasis on quality-of-life outcomes such as having greater independence, feeling better, and being able to return to daily activities.

These disparities between patient and provider preference in outcomes in TAVR highlight the importance of prospectively measuring patient and provider preferences in outcomes of transcatheter edge-to-edge repair (TEER) and surgical mitral valve repair (MVR), which share similar tradeoffs in decision-making. The ongoing Percutaneous or Surgical Repair In Mitral Prolapse And Regurgitation for ≥60 Year-olds (PRIMARY) trial will compare TEER to MVR in patients with primary, degenerative MR. To allow for the creation of a decision aid that can be utilize simultaneously with completion of the parent clinical trial, the investigators seek to conduct a quantitative and quality study of patient and physician factors that influence decision-making in TEER versus MVR for degenerative mitral regurgitation.

This study will consist of prospectively conducted qualitative focus groups among patients and providers (surgeons and cardiologists) to elicit the range of outcomes when considering TEER or MVR. These data will be analyzed to develop a consolidated framework of outcomes patients and providers value. Using these data, the investigators will then create and administer a quantitative survey to characterize how patients with severe MR and their providers prioritize outcomes when making treatment decisions and recommendations. The survey will include an allocation task whereby participants will be presented with a set of alternative treatment outcomes from the qualitative surveys and components of the PRIMARY composite endpoint and asked to allocate a total of 100 points across these outcomes based on their preferences. Lastly, the investigators will identify barriers and facilitators for implementing shared decision making (SDM) in multidisciplinary mitral valve hear teams by conducting qualitative focus groups across health care provider stakeholders (e.g. surgeons, cardiologists, nurses in office). These data will be used to map workflows and identify the optimal timing and process of integrating SDM in clinical care. In addition to generating process maps, an understanding of the implementation barriers and facilitators will aid in developing an approach to create and test an implementation strategy for SDM in severe degenerative MR. Collectively, these aims lay the foundation for developing and implementing a patient centered decision aid to support SDM in the future, but also model a novel approach for implementing the results of PRIMARY into routine clinical care.
