Background: Community based health and social resources can help individuals with complex health and social needs. However, there is often a discontinuation of patient care between primary care practices and community resources due to: a lack of physician or patient awareness of available resources; the presence of social barriers; the paucity of means to facilitate patients’ trajectory along the continuum of care; and more broadly, to the difficulties implementing organizational changes in primary care practices already busy providing health care services. Navigation services – where a person is tasked with helping connect patients to community resources – can strengthen continuity of care for patients. The implementation and study of the navigators’ impact is complex and warrants further investigation. Objective: Assess whether the ARC Model is feasible, including its potential to achieve its intended outcomes, and the viability of the evaluation approach. Methods: Describe the protocol of a single arm, prospective, explanatory mixed methods, pre-post design feasibility study, focusing on primary care practice settings with vulnerable populations. Participants include primary care providers, and patients. Results: Enrollment is closed with 82 patients. Navigation services have ended for 69 patients. Conclusions: Multilayered complex issues contribute to a high risk of failing to sustainably implement navigation services, thwarting randomized control trials’ effectiveness at assessing their impact. Undertaking a feasibility study from a conceptually clear and methodologically solid protocol will inform on the acceptability, ease of implementation, quality of integration, practicality and adaptation needs prior to initiating a randomized control trial.
