title: A systematic review on US-based community health navigator (CHN) interventions for cancer screening promotion--comparing community- versus clinic-based navigator models.
abstract: This study synthesized lessons learned from US-based community and clinic health navigator (CHN) interventions on cancer screening promotion to identify characteristics of models and approaches for addressing cancer disparities. The combination terms "cancer screening" and "community health workers or navigators" or "patient navigators" were used in searching Medline, CINAHL, and PsycInfo. A total of 27 articles published during January 2005∼April 2014 were included. Two CHN models were identified: community-based (15 studies) and clinic/hospital-based (12 studies). While both models used the term "navigators," most community-based programs referred them as community health workers/navigators/advisors, whereas clinic-based programs often called them patient navigators. Most community-based CHN interventions targeted specific racial/ethnic minority or rural groups, while clinic-based programs mostly targeted urban low income or mixed ethnic groups. Most community-based CHN programs outreached members from community networks, while clinic-based programs commonly worked with pre-identified in-service clients. Overall, regardless model type, CHNs had similar roles and responsibilities, and interventions demonstrated effective outcomes. Our review identified characteristics of CHN interventions with attention to different settings. Lessons learned have implication on the dissemination and implementation of CHN interventions for cancer screening promotion across setting and target groups.
