Comprehensive Geriatric Assessment for Frail Older People With Chronic Kidney Disease - The GOAL Trial

Comprehensive Geriatric Assessment for Frail Older People With Chronic Kidney Disease to Increase Attainment of Patient-Identified Goals - A Cluster Randomised Controlled Trial - The GOAL Trial

The GOAL trial addresses patient-prioritised research topics and outcomes and will be conducted, disseminated and implemented in partnership with patients and their caregivers. This will be the first study, internationally, to evaluate the clinical and cost effectiveness of Comprehensive Geriatric Assessment (CGA), a highly promising intervention for improving patient-important health outcomes in frail older people with Chronic Kidney Disease (CKD).

There is an increasing number of frail patients with CKD, and multiple morbidities. Many of them face rapid deterioration of health, referral to residential aged care facilities and loss of independence. This substantively impairs their quality of life and has societal ramifications, including very high costs of care. Patients and carers are often overwhelmed by the multitude of decisions they have to make and may follow a care path that is in contrast to their goals.

The GOAL trial addresses patient-prioritised research topics and outcomes and will be conducted, disseminated and implemented in partnership with patients and their caregivers.

The primary objective is to test the hypothesis that in frail older people with stages 3-5 CKD, Comprehensive Geriatric Assessment (compared with usual care) will increase attainment of patient-identified goals at 3 months follow up. The secondary objectives are to test the hypotheses that the Comprehensive Geriatric Assessment will increase attainment of patient-identified goals at 6 and 12 months follow up, improve their quality of life and reduce frailty, hospital and residential aged care facility admissions while being safe and cost-effective.

In this multicentre cluster randomised controlled trial, a total of 500 adult CKD stage 3-5 patients will be recruited. Sites will be randomly allocated to either provide a Comprehensive Geriatric Assessment to participants or usual care. The primary outcome measure is goal attainment scaling at 3 months follow up. The secondary outcome measures will be goal attainment scaling at 6 and 12 months, quality of life EQ-5D-5L, frailty index, mortality, hospital and residential aged care facility admissions and cost-utility analysis.

Inclusion Criteria for screening:

• Moderate to severe CKD as determined by the treating nephrologist:
• Stage 3 = eGFR 30 - 59 ml/min/1.73 m2
• Stage 4 = eGFR 15 - 29 ml/min/1.73 m2
• Stage 5/5D = eGFR below 15 ml/min/1.73m2, including patients receiving dialysis
• Aged ≥65 years, or ≥ 55 years if Aboriginal or Torres Strait Islander

For inclusion in enrolment:

• Frailty Index >0.25 (FI-CKD tool)

Exclusion Criteria:

• Estimated life expectancy of less than 12 months.
• Unable to provide informed consent and/or participate in the Goal Attainment Scaling process due to cognitive impairment or another reason.
