Despite efforts, pediatric HTx candidates continue to have high waitlist mortality due to limited donor availability. However, there is a significant number of offered hearts not used due to concerns of viability. ESHP is a method for continuous perfusion of the donor heart that allows assessment and extended out-of-body time. It is imperative to understand healthcare stakeholders' perspectives on ESHP for implementation. Therefore, the aims of this qualitative study were to: (1) Explore pediatric stakeholders' perspectives toward ESHP; and (2) Identify barriers to widespread adoption of this technology. Virtual focus groups were completed with pediatric HTx healthcare professional stakeholders. Following transcription of audio-recordings, the material was analyzed using content analysis. Four focus groups were completed with 17 participants, representing 12 institutions and three countries. Focus groups revealed varied understanding of both current and potential uses of ESHP. Participants did see the potential benefits of extending out-of-body time for and the ability to evaluate donor heart quality. However, concerns were expressed relating to patient selection, wait-list times, post-HTx outcomes, adverse events, and technical issues. These were felt to be important to understand in order to justify the costs of ESHP and impact on the healthcare system. This project represents the first qualitative formative evaluation of ESHP in pediatrics. The knowledge gained from stakeholders will form the basis for education initiatives, clinical trial design, and roll-out of new ESHP technologies designed for pediatrics.
