A Dual-centre, Two-arm, Open-label Randomized Controlled Trial Comparing an Integrated Collaborative Nurse-led Physician-supported Multimorbid Chronic Kidney Disease Care Model Versus Physician-led Care (INTEGREAT-CKD)

Study objectives:

1. To evaluate if a nurse-led model of care (INTEGREAT-CKD), in comparison to the standard of care (physician-led care), improves self-management skills, quality of life, and health literacy in patients with advanced CKD.
2. To assess if a nurse-led physician-supported consultation model of care, in comparison to the standard of care, optimizes the attainment of clinical targets following CKD best practice guidelines.
3. To assess if health resource utilization is cost-effective for complex CKD patients cared for by a nurse-led physician-supported consultation model of care compared to the standard of care.

Study design This study is a dual-centre two-arm, open-label randomized controlled trial (RCT). Patients are randomized with a one-to-one allocation into two parallel groups. Participants with advanced CKD referred to the tertiary institutions are randomized to either the control group (physician-led standard of care consultation model) or the experimental (intervention) group, which consists of enrolment in the INTEGREAT-CKD programme. INTEGREAT-CKD is a six-month programme consisting of an outpatient nurse-led consultation model, delivered by a team of CKD-trained Advanced Practice Nurses (APNs) and community-based nurses. Participants are reviewed in person at a 3-monthly interval by a CKD-trained APN independently. The CKD-trained APN's practice is supported by adherence to a protocol-based and algorithmic set of guidelines co-written by the CKD-trained APN and nephrologist for the main clinical aspects of CKD care. Each clinic session is allocated an extended duration of 30 minutes to educate patients on CKD-related medical knowledge, targeted lifestyle modification, and self-management skills. Questionnaires to determine patient's health literacy, self-management skills, and quality of life are assessed at the beginning and end of the study.

Setting:

The study will be conducted across two tertiary hospitals, Alexandra Hospital (AH) and National University Hospital (NUH), located in the western cluster of Singapore. Both hospitals are tertiary healthcare institutions that receive outpatient nephrology consult referrals, including consultation about CKD management, from within the institutions and primary healthcare sector within the western cluster.
