Abstract
OBJECTIVES: To assess the clinically relevant change in health state utility (HSU) in living kidney donors and whether this change value is constant across measures and clinical conditions and is useful for health economics studies. We aimed to 1) measure the change in the HSU score for living kidney donors from before donation to 3 months after donation and 2) estimate the minimal important decrease (MIDe) in the HSU score for living kidney donors and its associated clinical factors. METHODS: Data from a prospective multicenter observational study measuring quality of life of kidney donors by the three-level EuroQol five-dimensional questionnaire (EQ-5D-3L) and the six-dimensional health state short form (SF-6D) before donation and at 3 months after donation provided HSU scores. Two methods were used to derive the MIDe: the anchor-based method and the distribution-based (standard error of measurement) method. Logistic regression was used to identify clinical factors associated with the MIDe after donation. RESULTS: In total, 228 and 216 donors completed the EQ-5D-3L and the SF-6D, respectively. Mean HSU scores were 0.932 and 0.823 before donation and 0.895 and 0.764 at 3 months after donation. HSU scores were significantly decreased at 3 months, and 18.5% of donors rated their global health as "somewhat worse." By the EQ-5D-3L and the SF-6D, the MIDe was estimated at -0.113 and -0.116 with the anchor-based method and -0.075 and -0.077 with the distribution-based method. Risk of decreased HSU score was significantly associated with clinical complications but only marginally with surgical technique. CONCLUSIONS: A short-term clinically relevant decrease in HSU was significantly associated with clinical complications in kidney donors. Preventing perioperative complications is of prime importance in kidney donation.
