"You don't know what you don't know": A qualitative study of informational needs of patients, family members, and living donors to inform transplant system metrics.

Introduction: Informational needs and potential use of transplant metrics, especially among patients, remain understudied and a critical component of the transplant community's commitment to patient-centered care. We sought to understand the perspectives and needs of patients, family members/caregivers, living donors, and deceased donor family members.

Methods: We examined decision-making experiences and perspectives on the needs of these stakeholder groups for data about the national transplant system among 58 participants of 14 focus groups and 6 interviews.

Results: Three major themes emerged: 1) informational priorities and unmet needs (transplantation system processes, long-term outcomes data, prelisting data, patient-centered outcomes, and ability to compare centers and regions); 2) challenges obtaining relevant and trustworthy information (patient burden and effort, challenges with medical jargon, and difficulty finding trustworthy information); and 3) burden of facing the unknown (stress and anxiety leading to difficulty processing information, challenges facing the transplant journey when you "don't know what you don't know").

Conclusion: Patient, family member, and living donor participation in shared decision-making has been limited by inadequate access to patient-centered information. New metrics and patient-facing data presentations should address these content gaps using best practices to improve understanding and support shared decision-making.
