Abstract
Including target populations in the design and implementation of research trials has been one response to the growing health disparities endemic to our health care system, as well as an aid to study generalizability. One type of community-based participatory research is “Patient Centered-Research”, in which patient perspectives on the germane research questions and methodologies are incorporated into the study. The Patient-Centered Outcomes Research Institute (PCORI) has mandated that meaningful patient and stakeholder engagement be incorporated into all applications. As of March 2015, PCORI funded seven clinically-focused studies of patients with kidney disease. The goal of this paper is to synthesize the experiences of these studies to gain an understanding of how meaningful patient and stakeholder engagement can occur in clinical research of kidney diseases, and what the key barriers are to its implementation. Our collective experience suggests that successful implementation of a patient- and stakeholder-engaged research paradigm involves: (1) defining the roles and process for the incorporation of input; (2) identifying the particular patients and other stakeholders; (3) engaging patients and other stakeholders so they appreciate the value of their own participation and have personal investment in the research process; and (4) overcoming barriers and challenges that arise and threaten the productivity of the collaboration. It is our hope that the experiences of these studies will further interest and capacity for incorporating patient and stakeholder perspectives in research of kidney diseases.

Introduction
The notion that there is value in including members of the target population in the research team is not novel and some areas of medical research have a long history of patient involvement but it has been gaining broad scientific attention in the last decade (1,2). There are multiple terms and definitions used for this type of research. One of the most widely used terms is “community-based participatory research” (CBPR), which is often defined as a collaborative approach to research that equitably involves all partners in the research process and recognizes the unique strengths that each brings (3).
There are several factors that explain the increasing utilization of CBPR approaches in recent years (4). Researchers have begun to acknowledge that researcher-driven models have not successfully addressed the variety of health disparities that have become hallmarks of modern medicine. Furthermore, communities themselves are weary of being passive participants and are asserting their voices in setting the research agenda. With engaged partners, the process of disseminating the results back to the community is incorporated into the initial study framework, ensuring that the results have the highest potential impact and benefit for the community (5).
The term “Patient-Centered Research” can be used when a particular patient population is defined as the target CBPR community. Although coined several decades ago, the term achieved more widespread adoption following the Institute of Medicine’s landmark report Crossing the Quality Chasm (6). Specifically, patient-centered care is defined as:“Health care that establishes a partnership among practitioners, patients, and their families (when appropriate) to ensure that decisions respect patients’ wants, needs, and preferences and that the patients have the education and support they need to make decisions and participate in their own care.”
Patient-centered research is primarily concerned with addressing the questions of most importance to patients and enhancing decision making through the generation of evidence that is reliable and actionable for a patient’s unique circumstances. Traditional randomized controlled trials are costly, slow, and produce results that are often difficult to translate to routine practice (7–9). There is need for more integrated approaches that reflect research questions of relevance to patients, yield results considered actionable by practitioners, and provide information valuable to the populations most affected, which often means patients with complex, comorbid problems (10–13). It was out of this context that the Patient Protection and Affordable Care Act (Affordable Care Act 2010) authorized the Patient-Centered Outcomes Research Institute (PCORI), an independent, nonprofit, nongovernmental funding organization. The Institute’s charge is to improve the quality and relevance of evidence available to help patients, caregivers, clinicians, employers, insurers, and policy makers make informed health decisions (14). Notably, PCORI requires researchers to include a detailed engagement plan as part of all proposals, encouraging approaches informed by participatory action and comparative effectiveness models of research. Without being prescriptive with respect to specific approach, every application must describe a process to meaningfully involve patients, caregivers, clinicians, and other healthcare stakeholders throughout the research process. To aid researchers as they adapt to this changing landscape, PCORI developed their Engagement Rubric that highlights three key phases of research into which patient input can be incorporated: study design, implementation, and dissemination of the results (15). In a recent editorial, PCORI leadership offered descriptive evidence that patient engagement has largely been effective in impacting studies, but acknowledged that the studies are still too few and early to determine the impact on health outcomes. Furthermore, they identify that researchers are struggling with how to establish frameworks for patient engagement and how to meaningfully incorporate their input (16).
Herein, we explore the experiences among PCORI funded projects that target patients with kidney disease to gain an understanding of how meaningful patient and stakeholder engagement is being operationalized by the research team. As of March 2015, PCORI funded seven clinical studies that focused on patients with kidney disease (Table 1). The experiences and information presented here were gathered through informal survey, group discussions, and dialogue among study leadership and patient stakeholders. This manuscript represents nephrology’s early contributions to the evidence base as well as offers illustrative examples to highlight barriers to and facilitators of implementation success.
Studies funded by PCORI through March 2015 targeting patients with kidney diseases
Defining the Role of Patients and Other Stakeholders in Research
The first step to incorporating patient and stakeholder input into the research program is to have a clear vision of their desired roles. In the funded nephrology studies, patients’ roles even within their contributions to the study design were quite diverse, from providing data to helping develop meaningful power calculations, to reviewing the study protocol, to being active participants in the development of study questions and methodologies (Table 2). A major challenge to meaningful incorporation of patient and other stakeholder input is the usually tight timeline required for grant submission. Some of the studies had previous ongoing relationships with groups of patients and some were formed de novo for the purposes of the application. While all of the studies incorporated the patient perspective, the specific methodologies and scope of that involvement varied across studies.
Examples of patient engagement across the different studies
The following three examples highlight different perspectives on the scope of patient input. A description of the studies’ hypotheses is available in Table 1 and overview of their patient engagement process in Table 2.
Illustrative Example of the Scope of Patient Involvement (Hynes study)
In the Bringing Care to Patients: A Patient-Centered Medical Home for Kidney Disease study, the patient is emphasized as the key member of the healthcare team (17). Notably, patients and other stakeholders are invited to participate in quarterly discussion groups at each dialysis center to guide implementation of the intervention. The participants’ input helps the research team plan, implement, and evaluate the new care model, particularly with respect to availability of the primary care physician, pharmacist, and health promoters during dialysis treatment. Their input also helps researchers to gain insight into patient and family member educational needs and interests.
Illustrative Example of the Scope of Patient and Stakeholder Involvement (Mehrotra study)
During the early planning phase, conference calls were held with patient groups and dialysis providers in order to receive their input in developing the essential elements of the study design. In practice, both Patient and Stakeholder Councils contributed to the overall study design, and assisted in the development of each intervention and the selection of primary and secondary outcome measures. The Patient Council assisted the coinvestigators in developing a semistructured interview to ascertain study participants’ experiences with each intervention upon completion of participation. The dialysis provider partners facilitated communication with facility administrators, medical directors, and nephrologists in participating dialysis facilities to ensure smooth implementation of the protocol without interfering with clinical care.
Illustrative Example of the Roles of Patient and Stakeholder Involvement (Cope study)
The NephCure Kidney Network (NKN), was established to address critical gaps in primary nephrotic syndrome research infrastructure by its development as a patient-powered research network. The framework for patient and family engagement in health care was adapted from Carman et al. (18) to achieve both depth and breadth of involvement from the nephrotic syndrome community in creating and sustaining the NKN. In a patient-powered research network, control of the research process is held largely by patients in combination with other stakeholders, including caregivers, advocates, clinicians, and researchers. The active involvement of the patient perspective in the network ensures a central role for patient participation in governing the network and its uses, identifying and prioritizing research questions, recruiting patients to participate, defining data elements for collection, contributing to protocols, providing input on analyses and how results are presented, and disseminating research findings.
Across studies, patients varied in their desired degree of engagement, and sought different depths of engagement depending on a variety of factors including where they were in their own “patient journey”, their own health, and perceived ability to contribute meaningfully. To accommodate varying patient preferences, it is suggested that patients and other stakeholders should have the opportunity to be involved in structured roles independently throughout the continuum of engagement (consultation, involvement, and shared leadership) rather than encouraging all patients to seek shared leadership. This approach allows patients to adjust the depth of their involvement over time to fit their own needs.
Identification of Relevant Patient and Other Stakeholder Participants
Once the proposed roles of patients and stakeholders are defined, the task of identifying and recruiting the specific patients and stakeholders begins (19). In an extensive review of relevant literature about stakeholder engagement and interviews with research leaders, Guise et al. (20) concluded that explicit and consistent use of terminology about stakeholders was largely absent. The context and scope of the research topic will, to a great extent, determine the definition of each specific stakeholder, as well as the roles of the individual stakeholders at various stages of the research.
The next step in the process of stakeholder engagement is to determine baseline knowledge about the preliminary research question and whether formal training and education are needed prior to engagement. In a qualitative study of patients who had been engaged as stakeholders, the authors concluded that identification of the most appropriate stakeholders (characterized by confidence, motivation, intelligence, and focus on helping others) is more important than the type of training they receive (21). As part of the paradigm shift to early engagement of stakeholders, it seems appropriate to involve the stakeholders in the decision about the type and extent of training they desire. Desired engagement plans include early needs assessment of the target audience and continued repeated involvement of stakeholders (22,23).
Depending on the exact nature of the study, it may be particularly important to include perspectives from patient groups that have not traditionally been included in research (such as minority, elderly, and frail). Most of the nephrology studies have a formal Patient Council that interacts regularly with study leadership. Beyond that, studies utilized a variety of venues and modalities to solicit patient input, including direct survey of patient representatives, open solicitation of comment from target patient populations, national advocacy groups, tribal councils, and through clinical staff.
Illustrative Example of Patient and Stakeholder Identification (Cohen study)
Although the idea of inviting representatives from the national kidney patient advocacy organizations to be part of the project was initially entertained, it was decided instead to recruit patients and families from the clinics that would be studied. Two Patient Advisory Boards were created that were involved in all aspects of the project, including the two research studies. A Stakeholders Advisory Board was also instituted whose membership included representatives from the three proprietary dialysis organizations that operate the clinics, hospice administrators, dialysis nurses, a nephrologist, and social workers.
Illustrative Example of Patient and Stakeholder Identification (Tentori study)
Study investigators worked closely with a stakeholder advisory panel that was comprised of nine patients and family members, clinical nephrologists, social workers, and representatives from patient advocacy organizations. Given that priorities and needs are different for various patient types, they ensured that patient representatives included a range of ages, employment status, and experience with dialysis modalities. Patient members were highly functional patients, with a high level of involvement in their own health care decisions and often engaged in other research or education programs. The entire council collaborated in developing and testing interview protocols, and were key in developing the content and layout of the study’s decision aid. Throughout the study, the stakeholders provided insight on how best to implement the study, as well as detailed feedback on the focus of analysis of results.
Illustrative Example of Patient and Stakeholder Identification (Ghahramani study)
The researcher had a long-standing relationship with a local patient advocacy organization. As a member of the Board of Directors of the organization and a long-time instructor for the organization’s patient and caregiver mentoring program, he transformed a meaningful partnership into the base of the advisory council. A patient who also served on the board was engaged to provide the patient’s perspective on the research question. Similarly, a dialysis social worker, who worked closely with the advocacy organization and cared for patients on a regular basis, was in a unique position to serve as a research consultant drawing on long standing awareness of the day-to-day problems of patients with ESRD.
In dialogues with patient representatives from across the studies, one of the themes that emerged was that were more likely to provide input if they felt their contribution was valued. The patient representatives were more responsive if they could see their input incorporated into the study. The specific mechanism in which patient contribution is shared with study leadership should be explicitly stated and the reactions to the suggestions should also be patients shared. The more transparent the dialogue, the more likely the patients were to feel empowered in their roles. Furthermore, it would appear that having a specific individual from the study team serve as the liaison to the patient representatives serves to unify the experience for the patients. That person can, but need not, be the Principal Investigator for the study, but should be someone empowered to represent the research team to the patients, and the patient council to study leadership.
Challenges of Patient and Other Stakeholder Engagement
The stages of stakeholder engagement in research include: identification of the relevant stakeholders, definition of their roles, engagement, and maintaining engagement (14). There are both patient and system level barriers to effective engagement. The contextual factors in patient/stakeholder engagement are numerous and complex and include individual characteristics (e.g., age, self-efficacy, and literacy), disease characteristics (e.g., perception, stigma/taboos, comorbidities, and treatment demands), characteristics of the setting (e.g., type of provider, data driven care, incentives, information availability), and cultural/contextual norms. A common challenge is maintaining stakeholder engagement throughout the course of the study. In a qualitative analysis of multistakeholder projects in The Netherlands, patient involvement was rarely sustained (24). Determinants of involvement of patients and stakeholders include patient interest, attitude of the clinician, and insight about appropriate methods (25). Trust, usually based on prior relationships, is a key factor in maintaining engagement. For example, a researcher’s ties with a patient advocacy organization can greatly facilitate engagement of that organization in various stages of the proposed research. The trust and working relationship between the researcher and the advocacy organization is likely to generate trust with patients and other stakeholders such as caregivers. Some of the challenges in engaging stakeholders include: lack of a shared language with investigators and limited research training on the part of the patients; resistance of researchers toward questions generated by nonscientists; the optimal timing and level of stakeholder involvement; and ambiguities about ethical aspects of the engagement process (26,27). There are special ethical considerations in community-based research, and these issues may be further complicated if the “community” is not one in the traditional sense of the word, but rather a group of disparate people brought together by sharing a common illness (28).
Illustrative Example of the Challenges Associated with Patient Participation (Cohen study)
In preparing for the first meeting of the advisory board, the project coordinator made repeated contact with the seven potential members, proposed a mutually acceptable annual honorarium, discussed in detail how to participate in the inaugural conference call, and after considerable negotiation arrived at a mutually acceptable time. However, at the agreed upon hour, only two patients called in. During the ensuing conversations, it became apparent that all of the patients and families wished to take part in the project but none of them had ever participated in a conference call. Even members who were comfortable with computer technology found this daunting, unsure of how to get on the call and were unclear as to what to say or not say. They required practice, individual support, and further explanations before each was prepared to try again. For the next scheduled conference call, it was gratifying when six out of the seven members called in on time.
Illustrative Example of Patient and Stakeholder Barriers (Hynes study)
A key challenge for patient participation in the study’s patient council was due to the nature of the disease and its general toll on patients and their family members. For example, confirming attendance for a planned discussion group and arranging transportation was time consuming, and often uncertain in guaranteeing a quorum in advance of the session. The investigators also learned that ESRD patients’ attendance could be uncertain due to variability in disease progression, symptom exacerbation, and complications. Because of this, about 25% more patients were invited than were expected to attend a given session. Having a large percentage of patients who were primarily Spanish speaking was another important consideration. The investigators planned for bilingual staff and separate English and Spanish sessions, and held a session in both Spanish and English to accommodate as many patients as possible.
It has become clear that there cannot be a “one size fits all” model for stakeholder engagement. While it is useful to share models found to be successful in different situations, specific research situations often present different engagement challenges. Strategies for engaging patients and other stakeholders must incorporate an understanding of the unique environments in which patients exist and the potential barriers these environments pose and address them systematically.
Benefits of Patient and Other Stakeholder Engagement
Constructing a base of patients and other stakeholders who are ready to actively participate in multiple phases of the research process is a challenging and time consuming endeavor. However, we believe it is also one that will tangibly benefit the research and often the researcher. Successful engagement can provide the research team an opportunity to share in colearning, empathy, trust, and shared values with their patient populations, and provide them with a new perspective on the importance of the work. While we do not yet have empirical data on the ways patient input has affected health outcomes, we do have many examples of specific contributions made to the studies.
Illustrative Example of the Benefits of Other Stakeholder Involvement (Mehrotra Study)
After receiving the contract to evaluate treatment options for depression, but before the study was implemented, final approval from the dialysis provider organizations was needed. As the study proposed some novel treatment delivery options, the dialysis provider organizations did not have policies in place to address some of the needs. Their final approvals were secured in part due to the advocacy of their leadership representatives who had been part of the study calls during the planning of the study. Investigators were convinced that having the buy-in and input from the stakeholders from the start of the study was the key factor in their motivation to find creative solutions to accommodate the study at their respective sites.
Illustrative Example of the Benefits of Patient Involvement (Tentori Study)
Only patients and their caregivers have direct experience of living with kidney disease; consequently, investigators found the input from the advisory panel was invaluable in implementing each step of the study. As an example, the advisory panel provided extensive feedback on the protocol for qualitative studies, interview scripts, and data interpretation. The panel had strong opinions and was extremely vocal in the design and content development of the decision aid, to ensure that all aspects of the decision aid would be appropriate for the target audience of predialysis CKD patients and their caregivers.
Illustrative Example of the Benefits of Patient Involvement (Shah Study)
During the first phase of a pilot study by the Zuni Health Initiative, community members were engaged to identify perceived barriers to healthy lifestyles and healthcare utilization. Structural barriers that were identified included: the difficulty and expense of traveling to and from appointments; the difficulty of recruiting and retaining qualified healthcare providers; the perceived misdiagnosis or late diagnosis of disease; the perceived rationing of healthcare services; language barriers; and limited patient education (29,30). Additional psychologic barriers included anxiety; fear of chronic disease; reluctance to participate in self-care; resistance to dietary change; and reluctance to engage in regular exercise. With this information, the research team had a fuller appreciation of the challenges they would face in the implementation of their intervention.
Benefits and Challenges of Patient Stakeholder Involvement – Patient Perspective
Many of the patient representatives had very positive reactions to their time spent collaborating on the research projects. The representatives listed benefits to the studies due to their contributions, but also listed many personal benefits. One of the themes that emerged was the sense of empowerment that the study provided. Many patients feel overwhelmed by their illnesses and that their control over its course and prognosis is poor. However, being involved in research allows them to feel that their illness experience has more meaning if it can affect the larger community.
The most discussed challenges were finding time to prepare and participate in between the patients’ medical demands and doctors’ appointments. Beyond the scheduling two other themes emerged – the need for appropriate orientation and the need for transparency. One representative commented, “As the only lay person on the team and being the newcomer to a group of colleagues is a challenge. Fish out of water! Learning the research and medical lingo, with all their acronyms is a huge challenge!” An orientation session providing the background of the research team, its goals, and some of the relevant medical terminology, would have circumvented some of these difficulties. A different patient representative commented that she did not understand how the group was using her suggestions. “Am I a true partner here, and credit will be shared, or am I more of a consultant working in a think tank?” she wondered. Clear expectations set out at the beginning of the formation of the input mechanism are required for everyone to feel valued.
Discussion
Our collective experience suggests that successful implementation of a patient- and stakeholder- engaged research paradigm involves: (1) defining the roles and process for the incorporation of input; (2) identifying the particular patients and stakeholders to build a foundation of key stakeholders who appropriately represent the target treatment population and its caregivers; (3) engaging patients and stakeholders so they appreciate the value of their own participation and have personal investment in the research process; and (4) overcoming barriers and challenges that arise and threaten the productivity of the collaboration. Engaging patients may include educating them so they understand the research process and how it is connected to changes in clinical practice, and are therefore equipped to make meaningful contributions (31). Foundations of trust and mutual respect are key elements to being able to successfully navigate all of the foreseeable and unforeseeable challenges that present themselves over the course of a collaboration that may span many years and involve a great diversity of people engaged in the research. The numerous examples of patient engagement in research presented here suggest a growing movement within medicine in general, and specifically in those treating kidney disease.
We believe that the nephrology research community could serve as a model for implementing the ideals of CBPR and patient-centered methodologies. The treatment and research teams often develop long-term meaningful relationships with their patient populations due to the severity of the illness, its chronicity, and the substantial time burden associated with treatment. These relationships form the foundation of meaningful collaboration. This focus on patient engagement may be particularly meaningful in communities that have been traditionally disenfranchised by medical research. As there are many health disparities in renal disease, patients with kidney diseases from underserved communities may be particularly motivated to have a voice in their research and clinical agenda. There are similar advantages in engaging with dialysis provider organizations early in the research process. As dialysis centers are independent entities, it has been a logistic challenge for researchers to recruit enough patients to participate in trials. The meaningful involvement of provider organizations may also help the generalizability of the study, as it will aid in the implementation, dissemination, and sustainability of study findings. Researchers who wish to engage in stakeholder-engaged research must be genuinely open to incorporating perspectives that are legitimately different than their own, to overcoming any preconceived biases about the importance of this input, and must be able to lead a team that is more diverse than most research teams.
By working together to develop a culture of patient-centered research, we can improve and refine the selection of research questions and outcomes to be studied, enhance accrual and participant retention, and more appropriately disseminate and implement changes in clinical management identified by the research. Kidney research benefits from expanding the potential funders and from its successes. It is our hope that the innovations introduced by PCORI funded research will help patients and families and stimulate further interest in research and participation in kidney disease.
