Abstract

Outcomes relevant to treatment decision-making are inconsistently reported in trials involving glomerular disease. Here, we sought to establish a consensus-derived set of critically important outcomes designed to be reported in all future trials by using an online, international two-round Delphi survey in English. To develop this, patients with glomerular disease, caregivers and health professionals aged 18 years and older rated the importance of outcomes using a Likert scale and a Best-Worst scale. The absolute and relative importance was assessed and comments were analyzed thematically. Of 1198 participants who completed Round 1, 734 were patients/caregivers while 464 were health care professionals from 59 countries. Of 700 participants that completed Round 2, 412 were patients/caregivers and 288 were health care professionals. Need for dialysis or transplant, kidney function, death, cardiovascular disease, remission-relapse and life participation were the most important outcomes to patients/caregivers and health professionals. Patients/caregivers rated patient-reported outcomes higher while health care professionals rated hospitalization, death and remission/relapse higher. Four themes explained the reasons for their priorities: confronting death and compounded suffering, focusing on specific targets in glomerular disease, preserving meaning in life, and fostering self-management. Thus, consistent reporting of these critically important outcomes in all trials involving glomerular disease is hoped to improve patient-centered decision-making.

Keywords: consensus; glomerulonephritis; patient outcome assessment; treatment outcome; trials.
