Abstract

Patient navigation is a model of care that aims to improve access to care by reducing the complexity of navigating health, education, and social services across the continuum of care and care settings. Little is known about the processes that facilitate or impede the implementation of patient navigation programs (PNPs). We conducted a scoping review to identify and summarize the current state of knowledge regarding the implementation and outcomes of existing implemented PNPs. We employed a 6-stage scoping review framework to identify and review eligible articles. Sixty-articles met the inclusion criteria (58 peer-reviewed and 2 grey literature). The Consolidated Framework for Implementation Research served as the theoretical framework during analysis to help extract factors relevant to implementation of navigator programs. Results of the scoping review are reported thematically. Influences on implementation were identified: (a) planning to ensure alignment with organizational need (b) funding (c) multidisciplinary engagement (d) establishing workflow (e) mechanisms for communication (f) stakeholders to encourage buy-in (g) appropriate caseload (h) in kind resources. PNPs improve the experiences of patients and families. The findings of this scoping review provides implementation considerations of PNPs across global care settings. Strategies for overcoming pragmatic and logistical issues must be developed for optimal implementation.

Introduction

Navigating across the healthcare system can be very challenging, which may include having to transition between healthcare providers (HCPs), settings (eg, hospital to community), and stages of illness, and/or recovery. For adults with complex conditions (ie, multiple physical, mental, social, cultural, and/or spiritual needs) transitions across the healthcare system are common.^1-4 Transitions between HCPs and care settings are often fragmented, which limits patients’ access to services and hinders the quality and effectiveness of care.^5-7 Fragmentation of the healthcare system has been recognized as problematic worldwide.^8-10

The experiences of adults with complex conditions and their family caregivers (caregivers) navigating a fragmented healthcare system are largely negative.¹¹ Poor communication between patients and HCPs during transitions can lead to sub-optimal outcomes (eg, increased hospital re-admissions, being discharged to long-term care).^12-14 When patients and caregivers are cared for in an integrated system, they have better experiences and health outcomes (eg, better satisfaction with care, reduced feelings of caregiver burden).^15-18 For the purpose of this review, we define integrated care as care provided by a team of HCPs working together within and across settings.¹⁹

Based on the pioneering work of Doctor Freeman in the late 1980s,^20,21 patient navigation programs (PNPs) have gained traction across the globe as a solution to integrating care.²² Although the intent of Freeman’ first PNP was to improve breast cancer diagnostic and treatment services for African-American women,²³ PNPs now exist in the context of a variety of illnesses (eg, diabetes, hip-fractures, dementia).^24,25 Despite this increase in navigation-type programs, there is no unanimous definition of PNPs or the patient navigator role.^26,27 Likewise, significant gaps remain in the literature about processes that facilitate or impede implementation of PNPs as there is variation in the design and implementation of these programs.²⁵ We define PNPs as a program whereby a patient navigator provides patients and/or their family member with support in accessing healthcare resources.^28-30

Given the evolution of patient navigation (PN) over the past 30 years, numerous researchers have begun to synthesize the scientific literature on PN to help advance the field and inform future models of care. However, recent reviews published within the past 5 years in the area of PN have tended to focus on cancer,³¹ failed to consider grey literature where implemented programs may be described,²⁵ focused on adults aged 18 or older rather than adults with complex needs,³² and were constrained to areas of primary care.³³

For adult patients with complex needs, the type of support required often occurs outside of primary care in settings such as hospitals and rehabilitation.³⁴ No scoping review to date has summarized the characteristics of existing programs nor the facilitators to the successful implementation of PNPs that extend past primary care.³³ Existing reviews also do not report on the role of caregivers within navigator programs. This information is needed for stakeholders who plan to develop family-centered PN models of care for adults with complex needs. This scoping review aims to advance our knowledge about PNPs, which are an increasingly important topic for health services research. We present a synthesis of the current state of knowledge regarding the implementation considerations of PNPs to identify areas of further research and provide some initial practice recommendations.

Methods

Study design

We utilized a scoping review methodology based on Arksey and O’Malley’s³⁵ 6-stage methodological framework and the Preferred Reporting Items for Systematic Review and Meta-Analyses extension for Scoping Reviews (PRISMA-ScR).³⁶ A protocol for this study was registered prospectively with Open Science Framework (osf.io/a9ynh). Briefly, our methodology followed the following 6 stages: (1) identifying the research question; (2) identifying relevant studies; (3) study selection; (4) charting the data; (5) collating, summarizing, and reporting the results; and (6) consultation with stakeholders.³⁵ Table 1 details the methods we used for each stage.

Table 1.

Methods for conducting the scoping review.

Arksey and O’Malley³⁵ methodology stage	Study details
Stage 1: identifying the research question(s)	We collaborated with an interdisciplinary team of stakeholders (i.e., a current patient navigator, representatives from a not-for-profit community support service agency, the Director of Interprofessional Practice from a large urban hospital), to identify our research questions. Questions were also informed by the Consolidated Framework for Implementation Research (CFIR).³⁷ We identified the following research questions: (1).What is the scope of patient navigation programs available for adults age 26 y or older with complex needs?; (2) Who are the target patients of the existing programs? (3) When and how were these programs are developed and implemented? (4) What are the content of the programs and how does the content of these programs change to meet the needs of patients and families; (5) What are the reported impact of these programs on patient and caregiver outcomes?
Stage 2: identifying relevant studies	To identify peer-reviewed literature we searched CINAHL, Embase, Medline, Psych, JBI, Scopus, Web of Science, and PubMed on the 18th of October, 2020. The search strategy was tailored to each database using the key terms: “patient navigat”or “care navigat” and implement*. (See Supplemental Material 1 for Medline search strategy). References were imported into EndNote and duplicates were deleted. Following our inclusion and exclusion criteria (see Stage 3) we reviewed the reference lists of all included articles to determine any articles that we missed.
Stage 2: identifying relevant studies	To identify grey literature we searched Google and numerous national and international healthcare and government websites. We also reached out to key stakeholders, including members of our advisory group, to send us relevant reports and presentations.
Stage 3: study selection	The database searches produced 839 studies for consideration. After duplicates were eliminated, 419 articles remained. A two-phase screening process was undertaken. For Phase 1, three authors independently conducted title scans and abstract reviews to assess eligibility against the following inclusion criteria: (a) published from January 1990 to present, (b) implemented patient navigator program (PNP) for individuals aged 26 y or older with an acute complex condition or situation or a chronic condition(s), (c) peer-reviewed or grey literature, and (d) published in English. Articles were excluded if they were (a) published before 1990, (b) does not define their program as a “PNP,” (c) program was not implemented, (d) for youth (individuals 25 and under or the majority of the participants were 18-26), (e) books, book chapters, opinion pieces, or editorials, (f) grey literature that did not sufficiently describe the initiative implemented (eg, implementation process, location, population, impact), (g) literature reviews, protocols, trial papers, or chart reviews, (h) conference abstracts or articles without an accessible full-text, (i) does not describe one PNP but rather provides a summary or review of many programs and does not focus on implementation (eg, a survey on providers but not around the implementation of a program), (j) describes a patient navigation (PN) project that could be for adults and youth, and (k) describes a PN for a non-medical diagnosis (eg, smoking cessation) or a healthy population (eg, cancer screening program; diagnosis only) This resulted in the identification of 207 articles for full-text review. For Phase 2, 3 authors reviewed the articles using the same inclusion and exclusion criteria. Discrepancies were resolved by SLH KMK following a discussion of the article with. Fifty-eight met the inclusion/exclusion criteria and were included in the review. Our hand-search first revealed 11 additional articles, however after adding them to the full-text review process we did not identify any additional articles for inclusion in the review. (See Figure 1 for a PRISMA Flow Diagram of article selection).
	For grey literature, KMK and JESH first reviewed a total of 38. Grey literature had to meet the same inclusion criteria as the peer-reviewed articles. Twenty articles were considered. Grey literature that did not provide sufficient details on the implemented program (such as lacking a description of the components of the program, the outcomes of the program or the implementation process) were then excluded. Two grey literature sources were included.
	In total, 60 articles were included in our review.
Stage 4: charting the data	The entire research team discussed data characterization and extraction methods as a team at the beginning, during the middle, and at the end of the review process until a consensus was reached. The data were charted independently by KMK and JESH using a data extraction form in Microsoft Excel. Throughout data extraction Blinded for KMK and JESH met periodically to discuss emerging thoughts on the data. The form was developed and tested by the research team in a series of team meetings prior to the extraction of all data. Any questions that arose during the charting process were discussed by the team. The two extraction forms were compared for any discrepancies. No discrepancies were identified. Key information that was collected across article types included: general information, program, characteristics, patient, and caregiver population characteristics, implementation characteristics, study outcomes, and conclusions.
Stage 5: collating, summarizing, and reporting the results	KMK followed qualitative thematic analysis techniques, including developing a codebook and coding the data in Nvivo software to sort the extracted data according to crucial nuances in the data. Coded data was reviewed by JESH. Numerous meetings with the research team occurred whereby we discussed high level concepts and identified common themes across the included articles and in the coded data. The implementation process of each article was discussed in relevance to the components of the CFIR and summarized into descriptive themes characterizing components of implementation. Potential themes were discussed until consensus was achieved and final themes were developed with all members of the research team.
Stage 6: consultation with stakeholders	The research team presented findings of the scoping review to our advisory team of stakeholders through the planning process and analysis of results. These meetings were used to inform the analysis as well as to obtain relevant documents as previously described. Consultation with our stakeholders also helped to identify knowledge gaps in order to develop targeted and actionable recommendations for implementing future patient navigation programs and research.

The main objective of this review was to identify and summarize the current state of knowledge regarding the implementation and outcomes of existing implemented PNPs. We aimed to answer the following 5 questions: (1) What is the scope of PNPs available for adults age 26 years or older with complex needs?; (2) Who are the target patients of the existing programs? (3) How were these programs developed and implemented? (4) What is the content of the programs?; (5) What are the reported impact of these programs on patient and/or caregiver outcomes? We have chosen to define adults as individuals aged 26 or older, as much of the health service research classifies individuals aged 18 to 25 as young adults and individuals under 18 as youth, who have unique service needs different from the 26 and older adult population.³⁷

We define implementation as the processes intended to incorporate PN within an organization.³⁸ The Consolidated Framework for Implementation Research (CFIR) was used to explore the factors that may be encountered during process of implementation.³⁹ The CFIR is comprised of different categories of factors and domains proven to affect program implementation.³⁹ The CFIR was selected due to the wide range of constructs included in its domains and ability to be applied to examine a variety of health services.³⁹ The categories of implementation outlined by the CFIR domains (see Figure 1) assisted with the extraction of data (ie, inner setting, outer setting, individuals involved, process of implementation). In our paper, inner setting refers to the characteristics unique to the organization including patient needs, whereas outer setting includes the economic, political, and social context external to the organization.⁴⁰

Results

The database search identified 419 unique peer-reviewed articles that were screened for eligibility. Following title/abstract and full-text review, 60 articles were included in this scoping review. Fifty-eight articles came from the database searches and 2 sources from the grey literature searches (see Figure 2).

Characteristics of programs: Setting, mode, and study population

The initiatives varied in terms of the target chronic condition and the type of healthcare setting in which PNPs were implemented. Most programs were implemented in community settings such as outpatient clinic settings or individuals’ homes (n = 29)^{41-43,49,51-53,56,57,62,64,69-73,76-80,84,88,90-92,95,97,100} followed by hospitals (n = 26).^{28,44,45,47,4850,58-61,6365-68,7475,8185-87,8993,9698,99} Although PNPs were initiated in 1 setting, PNPs guided patients through care received at other health settings including primary care, hospitals, and outpatient centers.⁷⁷ Ten studies utilized follow-up care through home-visits.^{49,53,61,70,77,79,80,91,95} Three programs used a virtual (web or phone-based) application.^54,83,94. One study used a mobile medical unit for the purpose of diagnosis.⁹⁰ Table 3 outlines the delivery setting and mode of the interventions.

The initiatives most commonly targeted cancer (n = 40) (including breast, colorectal, cervical, head, and neck),^{28,41,4344,47-50,5254-56,5860,6263,65-69,71-76,7880-84,8790,9294,96-98} HIV (n = 5),^{42,61,64,88,91} diabetes (n = 1),⁵⁷ heart failure/cardiovascular disease (n = 2),^45,59 Hepatitis C (n = 2),^51,70 patients with complex social needs/multiple chronic conditions (n = 6),^{46,53,77,79,93,99} kidney transplant (n = 1),⁸⁹ and end-of-life/palliative care (n = 3).^49,95

Specific characteristics of the intended population (ie, age, sex, gender, ethnicity/race, education, marital status, household composition, employment status, comorbidities) were not reported in the majority of articles, except in instances where the intervention only included females (eg, in the context of cervical cancer⁹⁰) or males (eg, in the context of prostate cancer⁶⁵), Hispanic individuals,^49,90 Chinese individuals,⁸⁷ or American Indian/Alaska Native individuals.⁷¹ Some studies referred to their target population as low-income but did not define this term.^47,53,54,83 Of the studies that reported participant age, the mean ages were most often 55 to 65.^{43,44,48,50,52,55,57,62,70,72,75,81,83,87,93,95} The eldest included patient was 93.⁷²

Some programs also aimed to improve families’ experiences of care within the context of cancer.^{48,69,71,81,97} Four studies examined the perceptive and experiences of navigators.^67,80,84,89 One study explored the perspectives of HCPs (ie, medical administrators (non-clinicians), nurses, social workers physicians/physician assistants) on the implementation and impact of the navigation program.⁷⁸ Very few studies described the implementation of the PNP in detail.

Planning to ensure alignment with organizational need

Planning for program implementation was important for success. The initial step for most organizations was to determine the organizational need for the PNP. Many times, this was identifying barriers to care for specific patient populations (eg, Myers et al⁶⁴ and Wells et al⁷³ and having an organizational commitment in place to overcome barriers to care^{50,66,68,69,81,82,84,85,90,92,97}). Identifying care needs often occurred through formative research conducted by the program implementers and informed the design protocol.^50,65,73,87 Incorporating the implementation of a PNP into strategic plans of the organization demonstrated commitment.⁴³ System-level factors (ie, characteristics of healthcare systems) that also motivated organizations to implement a PNP included medical insurance and the need to improve coordinative care for patients when facing workforce shortages.^{46,49,65,66,79,85,87,90}

Following this planning phase, organizations had to determine the type of PNP to implement, the qualifications of the navigator, and define their responsibilities.^{43,46,48,68,73,79,82,90,92} In some instance, the navigator function was co-designed among operational leaders.⁹² The daily work schedule of the PN was also discussed.⁷⁹ One program described setting timelines for each of the navigators’ responsibilities.⁸² Clear inclusion and exclusion criteria for patients to enroll in the PNP, or to guide navigators in selecting patients also were established.^{48,60,63,71,79}

Funding

A crucial linkage between organizational willingness to implementing an effective PNP was the amount of funding available. Financial incentives to implement the PNP include the provision of initial funds to cover upfront costs from government granting agencies (including research funding),^{45,46,50,56,57,73,77,78,82,87,90} donations from physicians,⁵⁹ and foundations.^{43,44,59,69,71,79,90,92} The amount of funding often influenced the type of navigator to hire, as professional navigators were more costly and could hinder the sustainability of a program.^57,68 Some studies had the professional navigator as the only program-related cost,^44,59 whereas others used funding to pay patients for their enrollment in the initiative.⁵³ Further work to establish the cost-effectiveness through formal evaluations of the incentives were suggested as strategies to help overcome cost-related barriers to implementation.^43,70,77,96

Multidisciplinary engagement

Multidisciplinary engagement throughout all stages of the development and implementation processes can help improve the effective implementation of PNPs. Programs were largely implemented by hospital organizations, although specific leaders of the programs were often not discussed. In the articles that did discuss program leaders, these were often either community organizational leads,^{41,43,46,56,66,73,87,99} hospital administrators,^{63,65,75,81,85,96} or physicians.^{68,75,79,81,96} Some studies described the creation of an implementation committee that was composed of clinical, administrative, and research representatives.^65,73,81,82 Many times these committees provided ongoing feedback on program implementation and progress. Initiatives that described developing a mobile application did so in consultation with patient partners who also piloted the prototype.^54,83

Research staff were often included in program implementation. Research coordinators or assistants also served as a resource for all program evaluations and sometimes the delivery of the intervention^{45,49,50,77,87,92} and coordination of the administrative functions of the PNPs.^{45,67,68,71,90} Sometimes research staff facilitated ongoing coaching for navigators.⁷⁸ Embedding researchers within program delivery, however, could be a barrier to implementation for some populations (ie, Indigenous groups) who have reported mistrust of research.⁷¹ Likewise researchers reported difficulty working with hospital leadership having limited experience in research.⁵⁰ A strategy to encourage research collaboration was to certify that navigators knew why data were being collected.⁹²

Navigating a patient navigator’s role

There was a wide range in the content of the PNP. The most common definition for a PNP was a model of care delivery that incorporates elements of patient advocacy and health education^{49,57,64,68,86,90,96} to avoid delays in care.^{48,51,55,56,66,71,72,74,80,83,88,98}

Patient navigator qualifications included lay patient navigators defined as those with lived experience of a health condition or with the healthcare system who may be educated but have no formal training related to PN (n = 20), navigators without a clinical license who received training in case management or patient navigation (n = 15), navigators who were licensed HCPs (eg, nurses, social workers) (n = 17), and students in a HCP program (n = 1).

Scope of practice often began with diagnosis or suspected diagnosis.^60,62,63 Next the PN supported the adult during the assessment and referral to appropriate services.^59,63,66,67 Next PNs assisted with counselling⁵¹ during follow-up during treatment (eg, Gabel⁵²) and post-service discharge.^45,59 Patient navigators were also often tasked with providing ongoing health education tailored to the health literacy of the patients.^45,46,85 Throughout the care continuum, navigators aimed to address patients’ ongoing concerns and needs for support.^{47,49,69,80,96}

The duration and frequency of a navigators’ involvement was often unspecified. Sometimes articles reported the data collection period of the study rather than the duration of the navigator’s interaction with a patient. In the studies that did specify duration and frequency, there was great variability. Some programs stated that the PN could be available for as long as needed⁶⁸ whereas other programs specified a maximum of 3,^49,61 6,⁸³ 8,⁸⁸ 9,^41,91 or 12 months.^54,75,79,95 Frequency ranged from 2 in-person visits during the first month⁹¹ to phone calls or visits every 1 to 3 weeks^{52,54,61,78,95} to at least 5 home visits over 3 months⁴⁹ and a follow up at 6 and 12 month periods.^47,91 Some interventions tailored the frequency of follow up by a PN to the needs of the patient^58,63 such as by conducting weekly home visits for the first month, followed by bi-weekly visits during the second month, and then potentially monthly visits.⁷⁷

Few studies described the role of the navigator on supporting family members. Some studies described that the PN role included promoting patient and family empowerment, such as through delivering supportive care and education to support self-management.^48,49,81 Others described providing emotional support to families.⁵² One study described that the navigators were to help patients cope with family matters.⁵⁴

Establishing workflow

Alterations to workflows created by the introduction of PNPs may also influence program implementation,⁸⁷ as existing HCPs do not have the capacity to take on PN responsibilities.^{43,46,66,68,86} Strategies to overcome challenges related to existing workflows included leveraging existing organizational structures, such as using the same documentation systems and embedding navigators into existing teams.^{45,59,65,79,85,87,92,94,97} Similarly, some studies had the navigator work in dual roles such as being a navigator and a clinic nurse.^66,83 While competing priorities and demands of these navigators were not discussed, some studies discussed the challenges HCPs had in supporting PN.⁷¹ Nonetheless, ensuring role standardization and clear communication about the functions of the navigator minimized role confusion and any overlapping functions between existing clinical roles and the navigators.⁹²

Training and supervision

A handful of programs that utilized lay navigators connected them with a supervisor^{53,55,58,73,78,87} or professional, including a nurse, social worker, case manager, or community health educator to monitor adherence to care plans for patients.^{57,64,65,68,73,77,84,95} However, remote supervision by researchers caused difficulty in assessing navigator’s reliability.⁵⁰

The availability of individuals to support navigators training was also identified as critical factors to support program implementation. The training of navigators was not always described in detail within the included studies (eg, Nonzee et al⁶⁵). Formal training in navigation was sometimes taught by the senior principal investigator of the study,^63,77,78 educators of community health workers,^78,84,93 or medical directors or clinicians.^67,87,94,96 Some programs developed their own training curriculum through interdisciplinary collaboration (ie, between multidisciplinary clinicians, researchers, advisory committee).^50,67,92,95 The implementation sites also provided institutional orientation for navigators,^50,57,78 that included training on electronic medical records^65,92 and providing education to families.⁷⁴ Training occurred in person⁸⁹ or virtually⁹² and sometimes involved ongoing training^{58,61,78,92,93} and supplemental learning resources (eg, case studies).⁹⁵

Mechanisms for communication

Communication was also an important aspect of implementation. Several studies noted the prominence of communication between patients, navigators, and other HCPs.^{50,59,62,66,67,71,73,84,86,87,96} Communication between patients, HCPs, and navigators most often took place in person. Some communication was also provided via telephone (n = 30), including via texting or mobile chatting applications (n = 3), or email (n = 2). Some patients were difficult to reach due to a lack of a telephone number or migration and thus, served as a barrier to program delivery.^73,93

Communication between the individuals involved in the programs and ongoing communication between key stakeholders were often referred to, which can be seen as an enabler to implementation in some studies.^{50,63,66,67,73,82,87,89} Mechanisms of communication were often not described in detail, with many studies just referring to ongoing meetings between program implementers.^50,82,83,92 One study described that yearly retreats were held to encourage communication and team-building among navigators in the same program.⁴⁹ Other studies described employing peer-to-peer communication strategies⁶⁷ or weekly meetings to discuss progress or current patients.^{65,66,77,83,87,89} To provide education to the public, community presentations were often used.^45,58,80,92 One program also had a dedicated webpage that outlined the role of the navigators.⁹²

Communication between patients and navigators were seldom described. Mutual trust and open communication between patients and navigators may help facilitate the positive uptake of a PNP by patients.^58,84 One study described that navigators communicated with patients in a professional but friendly manner whereby they used lay terms to describe medical processes.⁸⁴ Another study reported disrespectful communication (ie, not consistently concerned and impolite tone) among the navigators toward the patients.⁸⁵

Stakeholders to encourage buy-in

The engagement of stakeholders as champions,^66,67,92 were most often physicians,^{52,68,73,79,81,82,92,96} hospital leaders,^82,85,96 partnering not-for-profit organizations,^56,69,89,92 or principle investigators (researchers)⁶³ may have influenced the implementation of PNPs. Champions were often utilized to help delineate the role of the PN in healthcare settings.^67,81,82,92 Likewise, some studies were championed by advisory boards comprising of community partners and/or family members and patients.^{63,65,73,81,82,87,95} Champions often had several years of experience in PN^50,63,65,69 and provided the program team with information about resources available to patients in the community.^51,73,95 Open and planned communication helped to encourage stakeholder relationships.^73,82,87

The uptake of PN may also be facilitated by interdisciplinary HCP engagement. Collaborations between professional staff at the organization and the PN may influence the buy-in of the organization hosting the PNP.^{62,66,67,73,75,82,90,96} While collaboration between physicians and navigators were strong,^76,79 navigators report difficulty collaborating with nurses and social workers, although reasons for this were not described.^59,96

Enhancing stakeholder partnership with partnering organizations was used as a strategy to help encourage referral support.^{56,62,71,73,76,82,90} The referral of patients by HCPs, community organizations, and healthcare clinics acted both as facilitators and barriers to implementation and acceptance of the PN role.^{44,47,5052,6265-67,7173,7476,7987,89-91,96} In addition to facilitating referrals, PNs often liaised with healthcare clinic staff to schedule appointments for patients.^51,58,75 The time to seek out potential patients to enroll in the PNP was reported as a challenge for programs.⁷¹

Appropriate caseload

Having an appropriate caseload could help program sustainability. In some cases HCPs were hesitant to refer to the navigators due to concerns over navigators’ caseload.⁷¹ Navigators who were overwhelmed by their caseload provided poor patient care.⁸⁵ The number of newly diagnosed patient referrals limited navigators’ caseload.⁴³

In-kind resources

Several authors described the available or lack of available resources to the program implementation team, including the availability of resources within an organization and organizational workflows. Resources often were developed as a result of a history of collaboration between organizations,^50,69 whereby formal partnerships became defined in a memorandum of understanding for the purpose of PN implementation.^87,90

Resources often included physical (eg, room availability)^{44,50,57,62,63,65,67,73,74,87} and technological infrastructure (eg, use of the electronic health record or dedicated phone lines/cell phones).^{42,45,4750,5254,5759,6065,7374,8791-94,96} Programs were able to adapt some of the electronic medical records or intake procedures to fit the needs of the PNs.^57,69,75,92 However, technology sometimes caused challenges for recruiting patients due to inconsistent or delayed documentation of diagnosed patients suitable for PN.⁷¹ Likewise, the manual entry of patient information by navigators may pose as a challenge for intervention dissemination.⁷⁵ Thus, mechanisms for improving early diagnosis reporting has been suggested.⁷¹ Often, physical resources meant having hospital partners to implement the program in areas where patient need was high (eg, locations whereby there are high levels of concentrated poverty and racial discrimination^{58,60,63,71,85,87,90,93,96}). Medical resource agreements for specific health services to increase service allocation also served as a resource factor important for implementation.^58,74,90 One study permitted navigators to give low-income patients financial resources to assist with their wellness.⁵³

Access to informational materials was also important for the implementation of PNPs aimed at improving patient education. Some programs developed or adapted their own educational resource materials to help facilitate patient education through the PN (eg, on medical procedures).^{47,49,69,73,87,90} In general the access to, or the creation of, appropriate, and easily available resource material was reported as a facilitator to implementation.^49,73,90 Appropriate educational materials often included ones suitable for a variety of individuals in terms of health literature and languages.^49,73,90

Patient and caregiver outcomes

The majority of studies provided evidence that the addition of navigators to a patient’s care team increases not only a patient’s overall satisfaction of their treatment, but also improved access to primary healthcare,^45,59,77 education,^87,90 adherence to medication,⁴⁷ treatment completion,^54,83 reduced wait-times,^57,71 and decreased the number of no-shows or appointment cancellations.⁶⁰ Medical records predominately analyzed to report on re-admission rates and decreased wait times (eg, Ferrante et al⁷⁹). Patient satisfaction was commonly measured using a survey instrument that was given to patients prior to working with a navigator, and after the service was complete.⁴³ However, Fleisher et al⁵⁰ administered a self-reported nine-item patient satisfaction survey at 4 and 12 weeks into the program. The results demonstrated a significant increase within that time period. Survey data collected by Rocque et al⁹⁶ on patient satisfaction was able to determine that 83% of patients in the program stated they were either satisfied or very satisfied attributing to how valuable a PNP can be. Mixed methods research were often employed in many of the studies in a combination of patient interviews and surveys in order to gather a more in-depth understanding of patients’ views on PNPs.⁶⁸ Administering surveys at strategic points in program implementation was instrumental in understanding patient satisfaction throughout the implementation process.

Studies utilizing qualitative instruments such as structured or semi-structured interviews, diaries, observations, or those that employed surveys for their data collection, were often interested in examining the emotional support a navigator can provide a patient. A more frequently observed form of emotional support by navigators was when the patient felt the navigator acted as a counselor to them during the treatment process.^47,69 Other forms of emotional support included developing a rapport with the patient, helping them to navigate the healthcare systems, and being attentive to their concerns.⁹⁶ Language, education, and a number of other factors can make it difficult for patients to fully grasp their illness and treatment plan. Emotional support was also reported by patients who were assigned a navigator from a similar cultural background, or who spoke the same language.^28,74

HCP outcomes

Few studies examined HCPs outcomes as the majority were focused on patient outcomes. Often surveys were given to navigators upon the completion of the program period or navigators participated in interviews in order to better understand their experience.⁹⁷ Generally navigators found their work rewarding.⁹⁷ Navigators reported feeling appreciated by both patient and family and felt they were able to help with a broader range of patient needs than other clinicians.⁹⁷ In some circumstances, it was reported by other HCPs that the navigator improved communication between the different members of a patient’s healthcare team and aided in facilitating interdisciplinary work.⁸¹

Discussion

The present scoping review characterized the various approaches being used to successfully implement PNPs across diverse care settings. The outcomes of evaluated PNPs demonstrate positive impacts on the experiences of patients, families, and HCPs. Positive outcomes could be attributed to navigators engaging with and advocating for patients. Our work expands on the original work by Freeman^20,21 by considering patient navigation for all adults. There was a lot of variability with the process to which PNPs were implemented, which results in a lack of standardized best-practices for implementing PNPs to improve access to, and the quality of, care. However common themes related to implementation emerged that can help advance implementation of PNPs for all adults and not just those with breast cancer as the original model suggests. For example, the most described approach to program implementation included focusing on the inner setting characteristics (CFIR; organizational) and individuals involved (CFIR; characteristics of the individuals). This involved multidisciplinary groups of individuals working toward an organizational commitment to improving barriers to care for particular groups of patients. Outer-setting factors such as funding and the availability of partnering organizations also influences program implementation. Suggestions for future research, practice, and policy are provided below to help inform the planning process of implementing PNPs into community and acute care settings.

Future research

Researchers may help facilitate the implementation of PNPs and thus are encouraged to continue their work in the delivery of PNPs. The implementation of PNPs can be impacted by differences in national healthcare culture and funding. The majority of PNPs have been implemented in the United States and thus, research done in other countries, particularly those with publicly funded medical services (eg, Canada), is encouraged. Such research would allow comparisons to be made in terms of patient/family outcomes and different implementation approaches based upon healthcare funding models. Our studies included mostly the patient perspective and thus, there is an opportunity for future research to explore the impact PNPs have on caregiver and stakeholder perspectives. A more fulsome understanding of the facilitators and barriers to PNPs from the perspective of leaders, decision-makers and advisory committees could help researchers make recommendations for strategies to address challenges to PNP implementation. Future work should explore the impact that HCP engagement (CFIR; inner-setting) has on implementing PNPs. Additionally, participant demographics (eg, income levels, education levels, comorbidities) were generally not reported. Future research should more fully capture participant characteristics so that differences in outcomes and differences in programs to meet the needs of patients by social location could be better understood. Future research evaluating PNPs should also focus on reporting on the characteristics of the community settings and hospital units to provide more contextual information about the inner setting influences on implementation for those looking to implement PNPs. Lastly, many authors have recommended that a cost-analysis of PNPs be conducted.³¹ We recommend future research explore the cost or cost-effectiveness of PN across disease continuums and in a variety of healthcare settings.

Policy

This review described some of the broad organizational-outer characteristics that were reported as influencing the implementation of PN initiatives. The majority of included studies reported that their PNPs were a response to the existing health system not adequately meeting the needs of patients. Thus, comprehensive policy is needed to enact system change to meet the needs of all patients.

The reported organizational characteristics are strongly influenced by the resources available to the program implementation team including individuals, funding, and resources (ie, location, technological). System-level (CFIR; outer setting) improvements such as creating policies and processes that encourage the implementation of PNPs are encouraged. Governments are encouraged to provide funding for acute and community healthcare settings looking to implement PNPs. As obtaining adequate levels of health service funding is an ongoing challenges, more research on the cost-effectiveness of PN and a variety of cost-effective implementation approaches to support PNPs may encourage governments and organizations to fund PNPs.

Practice

A lack of PNPs exist outside of North America and cancer care. Many of the included articles implemented PNPs in community-based settings, suggesting the feasibility e of meeting patients and families in these settings. Electronic (ie, email, phone) and virtual methods of program delivery may be useful for widespread PNPs. Special consideration should be taken by organizations to determine the most appropriate type of navigator and mechanism of delivery that would be best suited for their given setting and target population.

The implementation of PNP resulted in practice change for healthcare settings. Most PNPs were implemented by organizations and multidisciplinary teams. Practice change often required resources (human, physical, technological, and financial) and multidisciplinary leaders, consultants, and stakeholders to encourage buy-in. Other domains with the potential to impact implementing PNPs include (CFIR) outer-level factors (eg, existing barriers to care, external government funding), inner-level (eg, communication processes), individuals involved (eg, establishing workflow among various clinicians) and processes (eg, processes for referrals). Examined together, the implementation strategies identified in this review could provide the starting of a framework that can be used by service providers and researchers in the implementation and evaluation of PNPs to improve care to adult individuals. It is important that those looking to implement PNPs into standard healthcare practice be aware of strategies to overcome barriers to implementation over time. Moreover, as politics can either hinder or facilitate implementation,¹⁰¹ it is important that organizations implementing PNPs be nimble to, and aware of, changing political climates.

In order for organizations implementing PNPs to achieve their mandate, patients must be recruited to the program. Our review found that program recruitment was largely dependent upon stakeholder referrals, particularly from physicians. Thus, organizations must prioritize and address factors that impede physician support of PN. Having strong networks and effective, ongoing communication among HCPs within partnering organizations or the organization itself may help to facilitate patient referrals. Organizations are encouraged to develop resources to educate HCPs about the PNP and have referral systems that do not interrupt existing workflow. As reaching clinicians for referral training and PN education may be challenging for some organizations, multiple methods of communication such as face-to-face and email are encouraged.

Limitations

It is possible that some relevant articles were missed because the search was limited from January 1, 2009 to October 19, 2020 and conducted in English. However, to minimize the potential of missed articles a search strategy was comprehensive, peer-reviewed, and we conducted an in-depth search of grey literature.

Conclusions

In this paper, we synthesize the literature on the characteristics, outcomes, and implementation of PNPs. Patient navigators often begin their interaction with patients shortly after diagnosis and continue to assist with their treatment and care. Factors that may influence implementation are identified. Reviewing existing implemented programs can help shed light on the challenges that new adopters of PN may encounter. This review provides an important foundation to guide future research, policies, and practices aimed at implementing PNPs to improve patient and family experiences.
