N2 - Most older people with kidney failure choose between treatment with dialysis or conservative kidney management. The preferences underlying these decisions are poorly understood. Here, we performed a choice experiment, informed by qualitative research, to examine preferences for the characteristics of dialysis and conservative management among over-65- year-olds with eGFR of 20mls or under/min/1.73m2. Mixed logit and latent class analyses quantified the trade-offs between frequency and location of treatments, survival, and capability (the ability to do important activities), accounting for participants’ characteristics. Overall, 327 United Kingdom partakers across 23 centers (median age 77 years, eGFR 14mls/min/1.73m 2) needed 8%-59% absolute survival benefit two years after starting treatment to accept dialysis, with preferences for less frequent treatment and treatment at home. Significantly higher preferences for survival were seen amongst partnered participants (effect size 0.04, 95% confidence interval 0.02-0.06) and if better levels of capability were depicted (effect size 0.02, 0.01-0.03). Three latent classes were identified with divergent preferences for survival, capability, and location of care. Stated preferences indicated participants favored higher survival probabilities, but only if their capability was preserved and the location and frequency of care were acceptable. Subgroups may prioritize survival, hospital avoidance, or in-center care. Clinicians supporting people making kidney failure treatment decisions must explore their goals and values. Thus, investment in services that prioritize capability and ensure treatment is delivered at a frequency acceptable to people in their preferred location would enable provision of preference sensitive care.
