OBJECTIVES:
Approximately 30% of patients with end-stage kidney disease (ESKD) waitlisted for kidney transplant are highly sensitized against potential donor tissues due to preformed, donor-specific human leukocyte antigens (HLAs) from previous exposure to foreign antigens. Finding a compatible donor for patients with wide ranges of anti-HLA antibodies is extremely difficult. Many highly sensitized patients are unlikely to receive an organ offer placing them at risk of waitlist removal or death on dialysis. In collaboration with patients, advocacy groups and transplant surgeons, a discrete choice experiment was designed to understand the value patients with highly-sensitized ESKD unlikely to be transplanted place on selected attributes of two different therapeutic options: remaining on dialysis or proceeding with an at-risk HLA-incompatible kidney transplant. Understanding the value patients assign to factors associated with continuing dialysis or choosing HLA-incompatible kidney transplant surgery potentially benefits various key stakeholders including reimbursement authorities, healthcare providers involved in high-risk transplants, patient advocacy groups, and most importantly, patients with highly sensitized ESKD.METHODS: Data were collected following ISPOR Conjoint Analysis Task Force checklist of good research practices, beginning with developing realistic and meaningful attributes and levels. Attributes and levels were identified using a 4-step process: raw data collection by literature review and interviews/focus groups, data reduction, wording enhancement, and removing inappropriate attributes.
RESULTS: Results revealed the attributes as most important to patients in deciding between continuing dialysis or proceeding with an at-risk HLA-incompatible kidney transplant.
CONCLUSION: These attributes will be tested to determine the value patients place on each to better inform the decision-making process for patients and clinicians.Conference/Value in Health Info
