People living with cancer often require intensive support throughout their cancer journey. While cancer coordination services provide support accessing cancer care and understanding treatment options, many patients experience considerable health-related social needs (e.g. unemployment, financial insecurity) that impact their health and wellbeing. Health Navigator interventions address patients’ health-related social needs through ongoing support to access relevant support organisations in the community. This study assessed the feasibility and acceptability of a Health Navigator intervention to address the health-related social needs of a population living with cancer attending an outpatient oncology clinic in Australia.
