Exploring the roles, functions, and background of patient navigators and case managers: A scoping review

Background: Patient navigators and case managers are health care workers who aim to provide individualized assistance to patients facing significant health concerns. Although these roles emerged from distinct historical need, the terms are often used interchangeably in the literature and are described to have overlapping functions. Differences in the way that these roles are conceptualized across countries has led to a lack of clarity regarding the exact functions that each offer to patients, caregivers, and the health care system. Objectives: To differentiate the functions and backgrounds of patient navigators and case managers across settings and disease contexts. Design: This review was guided based on the PRISMA extension for scoping reviews using a five-step review process: identify the research questions; search and identify relevant studies; select studies based on a priori criterion; chart the data; and collate, summarize and report the results. Data sources: A search of the literature was undertaken in peer-reviewed databases (Medline, CINAHL, and PubMed) and the grey literature (Google and unpublished articles in online repositories). Review methods: Extracted data included information on patient navigators and/or case managers related to their reported background, training, and/or knowledge; roles and/or specific functions; clinical setting; and targeted condition or disease type. Results: The search strategy resulted in 10,523 articles. After applying the eligibility criteria during title and abstract evaluation, 468 full-text articles were reviewed, resulting in a total of 160 articles. Functions of patient navigators and case managers were organized into nine emerging categories: (1) advocacy; (2) care coordination; (3) case monitoring and patient needs assessment; (4) community engagement; (5) education; (6) administration and research activities; (7) psychosocial support; (8) navigation of services; and (9) reduction of barriers. The background and knowledge areas of each role were compared and contrasted, and three categories related to the practice context of each role were identified: (1) typical setting and care trajectory; (2) target patient population; and (3) mode of service delivery. Conclusions: The current study identified important differences in the functions between patient navigators and case managers. However, there remains significant ambiguity between the functions of these two roles. Standardized definitions detailing scope of practice, and allowing for inherent flexibility across different settings, are needed to improve service delivery. (C) 2019 Elsevier Ltd.
