Description of intervention(s) / exposure
A patient navigator program. The navigator will work with patients, caregivers, health professionals to achieve better care and health through involvement in the social, community and health organisational network. It is a complex intervention and will be individualised, tailored to the needs of the patients and families. The navigator will first identify the needs of the individuals and family, and then design the management plan. The navigator may work with the child and family on a daily basis (either face to face, or via telephone) or less frequently, depending upon the needs of the child and family. The minimal time spent for the child/family will be 10 - 15 minutes on a daily basis. The family will have access to the navigator for a minimum of 6 weeks to a maximum of 24 weeks. The navigator will follow a four-by-five matrix of task and network plan:
1. Identification of task categories for a specific patient and family: navigating tasks may consist of identifying and mitigating barriers with patients and healthcare professionals. They may include telling (explaining where and when a renal biopsy will be done), inquiring (asking about the potential barriers, such as language barriers to attend the next appointment after the biopsy), supporting (listening to the fears about the interventions) and coaching (discussing the potential questions the patients and families may wish to ask in the next appointment).
2. Facilitation for a specific patient and families: the navigator may coordinate communication, seek advice from non-medical and medical staff and help to bring patients in for the appointments. For example, the patient navigator may help the caregivers to keep track of appointments, particularly when the organisational and executive skills of the child are affected, provide social support, interpret health information provided by the clinicians and facilitate communication within the families when parents are separated. Navigators may help patients to forge a more participatory dialogue with their clinicians, and guiding the patients to ask the right questions, enhancing patient autonomy. Patient navigators can also provide support for caregivers; e.g. managing transport to and from the hospital or coping with the complex organisational network within the hospital, particularly for those of lower literacy, low SES and families from non-English speaking backgrounds.
3. Identification of networks: the navigators will identify all potential network interactions that are relevant to the patients and their families. These may include: the health service providers, the non-clinical staff (administrators and receptionist), and other social support services such as the social workers, community-based services, transportation, and the maintenance of activities and system tasks for patients. These potential networks will be given to patients and family, ensuring they have full understanding and access to all the services required.
4. Document and review: the navigator will record their own actions (for example: steps taken with or on behalf of the patients and record other activities that are relevant to the navigator role).

Comparator / control treatment
The waitlist control is standard care. The control arm (standard care) involved the provision of general care provided by the healthcare professionals in the hospital and outpatient settings without the support of a patient navigator. The waitlist, controlled design has the benefit of allowing all eligible participants to be enrolled and receive the same intervention for the same duration of time, but staggered entry at different time points (different waves) such that participants with delayed entry will serve as controls.

Timepoint [5] 349297 0
1, 5 and 10-year
Secondary outcome [6] 349298 0
Direct health care costs and resource use. Healthcare resource use will be estimated using linked data including hospitalisation records, and Medicare Australia data for outpatient healthcare use (Pharmaceutical Benefit Scheme (PBS) and Medicare Benefits Schedule (MBS). Cost will be estimated by applying DRG or Medicare unit costs and will also include the costs of the patient navigator program.
Timepoint [6] 349298 0
Linkage will occur 12 month after completion of the study.
Secondary outcome [7] 349365 0
Patient perceived access to care (study specific questionnaire)

Brief summary
The NAVKID2 trial is a multi-centre, staggered entry, waitlisted randomised controlled trial that assesses the health benefits and costs of a patient navigator program in children with chronic kidney disease (CKD) stages 3-5, on dialysis (CKD-D) and with kidney transplants (CKD-T) and of low socioeconomic backgrounds. CKD is a devastating illness associated with increased mortality, reduced quality of life, impaired growth, neurocognitive impairment and psychosocial maladjustment in children. The overall annual mortality rate for children on dialysis is 35 per 1000 population and is thirty-fold higher than children without CKD. Such large discrepancies in mortality rates remain unchanged despite medical advances over the past two decades. The key findings of our observational KCAD study indicated that poor health in children with CKD is not only attributed to the direct influence of the chronic illness but also reflects outcomes of the complex pathway that defines equitable access to healthcare. We found that children with CKD of the lowest and second lowest socioeconomic status (SES) quartiles were at least 3 and 2 times more likely to experience poorer overall health compared to the highest SES quartile.
Patient navigators are trained non-medical personnel who assist patients with complex and/or chronic conditions journey through the continuum of care and transit across different care settings. They help the vulnerable and underserved populations with chronic illness to better understand their diagnoses, treatment options, and available resources, to guide them through the very complex medical system and to overcome barriers to health care access and bridge gaps in transitions of care. Using a staggered entry, waitlist randomised control design, this study will aim to: 1. Assesses the impact of a patient navigator program on the overall health and well-being of children with CKD in a multi-centre, staggered-entry, waitlisted randomised controlled trial.
2. Determine the cost-effectiveness of a patient-navigator program compare with standard care.
3. Identify the barriers and facilitators of developing and implementing a patient navigator program in clinical practice.
