Within WP1 the overall structure of the project, including responsibilities of each consortium partner, work packages (WP) and tasks of WP leaders and a communication strategy to communicate progress or identify challenges to the efficient implementation of tasks were outlined. So far, three consortium meetings have been held. By now all planned milestones have been met and all deliverables submitted for review. In WP2 the development of a co-adapted Health Navigator Model (HNM), meeting the needs of organizations, health care professionals and people experiencing homelessness (PEH) was accomplished. This was concluded through a systematic scoping review of literature on patient navigation (PN) to define the theoretical foundation of the HNM for PEH. Common scientific guidelines and tools for the cross-national research team were developed to ensure both consistency and quality. Qualitative interviews with PEH and health care professionals (n=69) were then conducted to explore general health care needs and barriers for PEH accessing primary and secondary cancer prevention across the four partner countries and co-adaptation focus group discussions (n=56) were concluded to define the HNM parameters. WP3 involves the pilot implementation of the HNM in four partner countries (Austria, Greece, Spain and the UK). Here development of guidelines and materials for capacity building for Health Navigators (HN) and their translation into the languages of the pilot sites were concluded. Further, pilot implementation plans were developed which describe the implemented methodology per pilot site. The pilot implementation started in June 2022 and will last 18 months. To date, 11 health navigators (HNs) have been trained in the use of the HNM, 243 PEH have participated in the project and more than 650 referrals to various cancer prevention services have been done. WP4 performs the formative and summative evaluation of the HNM pilot implementation. This includes an iterative evaluation in which both quantitative and qualitative data is collected, which provides the first evidence on the clinical utility and effectiveness of the HNM intervention among PEH in Europe. Currently, the evaluation of the HNM intervention is taking place in the form of researcher-administered questionnaires, interviews and focus group discussions. The communication activities (WP6) aim to promote societal knowledge about health inequalities and, in particular, to illustrate the barriers PEH face in accessing cancer prevention and how the HNM works in general. Further, the results will enable further inquiries in this under-researched area and promote science communication to increase awareness and visibility of cancer prevention in PEH. In addition, CANCERLESS is building relationships with decision-makers and civil society organizations and generates local and global alliances to scale-up the HNM derived from the project. WP7 and WP8 ensures the ethics and data protection regulations and that partners comply with these regulations during the whole project cycle. This included successful permissions from local responsible ethical committees, formation of an Ethical Advisory Board as well as registration with ClinicalTrials.gov by the Medical University of Vienna (NCT05406687).
