Empowering People Experiencing Homelessness for cancer prevention using the Health Navigator Model

Abstract Cancer poses a significant public health concern. Reports highlight that cancer-related mortality rates are double among people experiencing homelessness (PEH). CANCERLESS project delivered an innovative solution based on the Health Navigator Model (HNM). The HNM is an evidence-based patient-centred intervention that develops patient empowerment through health education and social support, promoting timely access to cancer prevention services. A pre-post design study conducted across four pilot sites in Europe (Austria, Greece, Spain, UK) involved 652 PEHs. Pilot interventions based on the HNM were implemented, with effectiveness evaluated at baseline and post-intervention. The study assessed the impact of the HNM on various factors including risk behaviors, lifestyles, quality of life, empowerment, health literacy, psychological distress and utilization of health and care services. Preliminary findings from CANCERLESS HNM intervention showed significant improvements (p= .000) in participants’ quality of life (55.82 (27.65) vs. 66.18 (22.27)) and sense of empowerment (25.58 (19.95) vs. 59.94 (43.10)). However, there were no observable impacts in health literacy (p= .509) or psychological distress (p= .140), which remained within acceptable ranges both pre- and post-intervention. Similarly, there were no significant changes observed in lifestyle or risk behaviours among PEHs. Nonetheless, the evaluation of effectiveness suggested that the HNM increase in the uptake of cancer prevention care, such as cancer screening (p= .000). The CANCERLESS HNM intervention significantly improved the quality of life and empowerment of PEHs. Additionally, it successfully promoted their involvement in cancer prevention efforts, addressing disparities in access to preventive healthcare services. Increased engagement in such initiatives can lead to early detection and treatment, ultimately reducing cancer morbidity and mortality rates, thereby positively impacting public health. Key messages • By promoting health equity and social justice, interventions like CANCERLESS HNM contribute to building healthier and more resilient public health systems. • CANCERLESS boosts cancer prevention awareness, tackles healthcare disparities, enhances cancer early detection, benefiting public health.
