The Role of Patient Navigators in Ambulatory Care: Overview of Systematic Reviews
Abstract Background: Patient navigators have been introduced across various countries to enable timely access to healthcare services and ensure completion of diagnosis and follow-up of care. There is an increasing amount of evidence on the positive effect of patient navigation for patients. The aim of this study was to analyse the evidence on patient navigation interventions in ambulatory care and to evaluate their effects on individuals and health system outcomes.Methods: An overview of reviews was conducted, based on a prespecified protocol. All patients in ambulatory care or transitional care setting were included in this review as long as it was related to the role of patient navigators. The study analysed all roles of patient navigators covering a wide range of health professionals such as physicians, nurses, pharmacists, social workers as well as lay health workers or community-based workers with no or very limited training. Studies including patient-related measures and health system-related outcomes were eligible for inclusion. A rigorous data collection was performed in multiple data bases. After reaching an inter-rater agreement, title and abstract screening was independently performed. Of an initial 8362 search results a total of 673 articles were eligible for full-text screening. An extraction form was used to analyse the nine included review.Results: Nine systematic reviews were included covering various patient navigation roles in cancer care, disease screening and transitional care. Seven systematic reviews primarily tailored services to ethnic minorities or other disadvantaged groups. Patient navigators performed tasks such as providing education and counselling, translations, home visits, outreach, scheduling of appointments and follow-up. Six reviews identified positive outcomes in expanding access to care, in particular for vulnerable patient groups. Two reviews on patient navigation in transitional care reported improved patient outcomes and hospital readmission rates and mixed evidence on quality of life and emergency department visits.Conclusions: Patient navigators have shown to expand access to screenings and health services for vulnerable patients or population groups who tend to underuse health services.
