Background. Although patient decision aids (PtDAs) have been shown to improve patient knowledge and satisfaction, they are infrequently used in the real world. We aimed to understand how our publicly available PtDAs developed for destination therapy left ventricular assist device (DT LVAD) were implemented in clinical practice and characterize factors influencing adoption. Methods. We contacted 39 people, 31 who had independently emailed inquiring about our DT LVAD PtDAs and 8 identified through snowball sampling. Thirty people from 23 programs participated in semistructured interviews, which were analyzed using normalization process theory. Results. Eleven programs currently use the PtDAs, 5 plan to use them but have not yet, and 7 do not currently use them nor have active plans to use them. Due to major tradeoffs and preference sensitivity of the DT LVAD decision, participants recognized a role for shared decision making and a need for significant information transfer. Due to a relative lack of resources, participants saw the PtDAs as a way to help facilitate a higher quality decision-making process. Limited time, lack of personnel, and perceived burden to implementing system-level change were cited as barriers to use. Initial implementation was accomplished by a champion of the PtDAs. Actual use of the PtDAs most commonly occurred through LVAD coordinators at the start of formal patient teaching sessions, where the PtDAs could be integrated into the existing LVAD consent and education structure. Conclusion. Interest in and implementation of PtDAs occurred independently at several LVAD programs due to a favorable decisional context, including a perceived role for shared decision making in the high-stakes decision around DT LVAD, unmet informational needs, preexisting education sessions, and invested clinical champions.
