Abstract
Background: Cervical cancer incidence and mortality rates are up to four-fold higher among people experiencing homelessness (PEH) compared to the housed US population. Even beyond typical social and structural barriers to healthcare, homeless women experience high rates of sexual violence and trauma, often leading to discomfort with cervical cancer screening and delays/refusals of Pap tests. Despite these issues, strategies for appropriate cervical cancer screening in homeless communities are scarce, and no frameworks exist for routine screening in shelters. Methods: Leveraging an established multisectoral community-academic partnership addressing homelessness and health disparities in Indiana, USA, ongoing community-engaged research is examining barriers to cervical cancer screening among PEH and co-designing strategies to address them. Rapid assessment surveys were conducted with PEH at two large homeless service agencies in Indianapolis and Lafayette to document cervical cancer screening coverage and characteristics of individuals who are unscreened/overdue. In-depth interviews explored knowledge of cervical cancer, key barriers and facilitators to screening, and acceptability of shelter-based HPV self-sampling delivered by trusted community health workers (CHW). Results: Of n=167 survey respondents, 48% were white, 38% Black, 7% Hispanic, 7% other. Mean age was 43.18 years, and mean lifetime years of homelessness was 3.18. Nearly half of participants (49%) were unsheltered, 44% stayed at a shelter, the remainder couch-surfed. One third (32%) were unscreened or overdue for screening, far above state and national averages (24% and 22% respectively). The majority (84%) reported wanting to be screened and believing it is important for their health. Provider mistrust and competing priorities surrounding their homelessness were main reported barriers to screening. Qualitative findings identified key benefits, concerns, and preferences for HPV self-sampling, with many participants expressing interest and willingness to adopt this screening method. Conclusion: Despite a vast majority of PEH reporting a desire and willingness to be screened for cervical cancer, key identified barriers limit access for this uniquely vulnerable population. Ongoing qualitative analysis is directly informing community context-specific CHW-delivered cervical cancer education and HPV self- sampling interventions. This work will ultimately lead to broadly implementable strategies for shelter-based routine cancer screening and preventive healthcare delivery for PEH.
