IntroductionThe GOAL trial, a cluster-randomised controlled trial, investigated the effect of comprehensive geriatric assessment (CGA) on frail older people with chronic kidney disease (CKD). This paper describes (1) participant baseline characteristics, and (2) their relationship with CKD stage and frailty severity. MethodsSixteen kidney outpatient clinics (clusters) were randomly allocated 1:1 to CGA or usual care. Enrolled frail older people with CKD (Frailty Index >0.25; aged ≥65 years or ≥55 if First Nations people) received the intervention allocated to their cluster. CKD was defined as moderate (stages 3/4) or severe (stage 5/5D), and frailty categorised as moderate (>0.25 to <0.36), severe (0.36 to <0.45) or very severe (≥0.45). Participant characteristics were analysed using descriptive statistics. Statistical methods appropriate for type of outcome were used to describe the association of frailty and CKD categories with participant characteristics. ResultsOver a 27-month period, 240 people were recruited (55.7% male, 82.9% white/European). Mean age was 76.9 (SD: 6.6) and median FI was 0.39 (IQR: 0.32 – 0.47). The median EQ-5D-5L quality of life index score was worse in those with very severe frailty (0.57, IQR: 0.28 – 0.83) compared to severe frailty (0.85, IQR: 0.67 – 0.92) and moderate frailty (0.90, IQR: 0.82 – 0.93) (overall P <0.001). Median EQ-5D-5L was also worse in those with severe CKD (0.79, IQR: 0.40 – 0.89), compared to moderate CKD (median 0.87, IQR: 0.73 – 0.92; P 0.001). ConclusionThis cohort demonstrated poorer quality of life scores in those with more severe frailty and more advanced CKD.
