UK research funding bodies' views towards public participation in health-related research decisions: an exploratory study

The INSIGHT project: reflections on the co-production of a quality recognition programme to showcase excellence in public involvement in health and care research

BACKGROUND

The quality of Patient and Public Involvement (PPI) in healthcare research varies considerably and is frequently tokenistic. We aimed to co-produce the Insight | Public Involvement Quality Recognition and Awards programme, based on the UK Standards for Public Involvement (UKSPI) alongside an incremental scale designed by Expert Citizens (a lived experience-led community group), to incentivise and celebrate continuous improvement in PPI.

METHODS

We used Task and Finish Groups (19/44 [43%] public contributor membership) to co-produce the programme which we piloted in three organisations with different healthcare research models. We used surveys and review sessions to capture learning and reflections.

RESULTS

We co-created: (1) A Quality descriptor matrix comprising four incremental quality levels (Welcoming, Listening, Learning, Leading) for each UKSPI standard. (2) An assessment framework including guidance materials, self-assessment form and final report template. (3) An assessor training package. (4) The quality awards event format and nomination form. These materials were modified based on pilot-site feedback. Of survey respondents: 94.4% felt they had made at least 'Some' personal contribution (half said 'Quite a lot'/'A great deal'), 88.9% said they were 'Always'/'Often' able to express their views freely and, 100% stated the programme would have 'A lot of impact'/'Quite a bit of impact'. During the project, we identified the importance of taking time to explain project aims and contributor roles, adapting to the needs of individual contributors and, using smaller bespoke sessions outside the main Task and Finish Groups.

CONCLUSIONS

We co-produced and piloted a quality recognition programme to incentivise and celebrate continuous quality improvement in PPI. One public contributor stated, "I feel strongly that the Insight framework and awards will raise awareness of the [public involvement] work going on in many community settings. [It] is likely to result in better sharing of positive practice, incentivising research groups of any size to start work or to improve the quality of [PPI] could be one of the main benefits. I'm excited that if this initiative takes off, regionally and then in the longer term nationally, it could be a significant step in advancing the [public] voice."

The benefits, challenges, and best practice for patient and public involvement in evidence synthesis: A systematic review and thematic synthesis

INTRODUCTION

Despite the growing evidence on patient and public involvement (PPI) in health research, little emphasis has been placed on understanding its quality and appropriateness to evidence synthesis (ES) and systematic reviews (SR). This study aimed to synthesise qualitative evidence on the benefits, challenges, and best practices for PPI in ES/SR projects from the perspectives of patients/public and researchers.

METHODS

We searched Ovid MEDLINE, Ovid EMBASE, Cochrane Library and CINAHL Plus. We also searched relevant grey literature and conducted hand-searching to identify qualitative studies which report the benefits and challenges of PPI in individual ES/SR projects. Studies were independently screened by two reviewers for inclusion and appraised using the Joanna Briggs Institute's Qualitative Tool. Included studies were synthesised narratively using thematic synthesis.

RESULTS

The literature search retrieved 9923 articles, of which eight studies were included in this review. Five themes on benefits emerged: two from patients'/public's perspective-gaining knowledge, and empowerment; and three from researchers' perspective-enhancing relevance, improving quality, and enhancing dissemination of findings. Six themes on challenges were identified: three from patients'/public's perspective-poor communication, time and low self-esteem; and three from researchers' perspective-balancing inputs and managing relations, time, and resources and training. Concerning recommendations for best practice, four themes emerged: provision of sufficient time and resources, developing a clear recruitment plan, provision of sufficient training and support, and the need to foster positive working relationships.

CONCLUSION

Highlighting the benefits and challenges of PPI in ES/SR projects from different stakeholder perspectives is essential to understand the process and contextual factors and facilitate meaningful PPI in ES/SR projects. Future research should focus on the utilisation of existing frameworks (e.g., Authors and Consumers Together Impacting on eVidencE [ACTIVE] framework) by researchers to help describe and/or report the best approaches and methods for involving patients/public in ES/SRs projects.

PATIENT AND PUBLIC CONTRIBUTION

This review received great contributions from a recognised PPI partner, the Chair of the Cochrane Consumer Network Executive, to inform the final stage of the review (i.e., interpretation, publication and dissemination of findings). The PPI partner has been included as an author of this review.

How should communities be meaningfully engaged (if at all) when setting priorities for biomedical research? Perspectives from the biomedical research community

BACKGROUND

There is now rising consensus that community engagement is ethically and scientifically essential for all types of health research. Yet debate continues about the moral aims, methods and appropriate timing in the research cycle for community engagement to occur, and whether the answer should vary between different types of health research. Co-design and collaborative partnership approaches that involve engagement during priority-setting, for example, are common in many forms of applied health research but are not regular practice in biomedical research. In this study, we empirically examine the normative question: should communities be engaged when setting priorities for biomedical research projects, and, if so, how and for what purpose?

METHODS

We conducted in-depth interviews with 31 members of the biomedical research community from the UK, Australia, and African countries who had engaged communities in their work. Interview data were thematically analysed.

RESULTS

Our study shows that biomedical researchers and community engagement experts strongly support engagement in biomedical research priority-setting, except under certain circumstances where it may be harmful to communities. However, they gave two distinct responses on what ethical purpose it should serve-either empowerment or instrumental goals-and their perspectives on how it should achieve those goals also varied. Three engagement approaches were suggested: community-initiated, synergistic, and consultative. Pre-engagement essentials and barriers to meaningful engagement in biomedical research priority-setting are also reported.

CONCLUSIONS

This study offers initial evidence that meaningful engagement in priority-setting should potentially be defined slightly differently for biomedical research relative to certain types of applied health research and that engagement practice in biomedical research should not be dominated by instrumental goals and approaches, as is presently the case.

Peer review in funding-by-lottery: A systematic overview and expansion

Despite the surging interest in introducing lottery mechanisms into decision-making procedures for science funding bodies, the discourse on funding-by-lottery remains underdeveloped and, at times, misleading. Funding-by-lottery is sometimes presented as if it were a single mechanism when, in reality, there are many funding-by-lottery mechanisms with important distinguishing features. Moreover, funding-by-lottery is sometimes portrayed as an alternative to traditional methods of peer review when peer review is still used within funding-by-lottery approaches. This obscures a proper analysis of the (hypothetical and actual) variants of funding-by-lottery and important differences amongst them. The goal of this article is to provide a preliminary taxonomy of funding-by-lottery variants and evaluate how the existing evidence on peer review might lend differentiated support for variants of funding-by-lottery. Moreover, I point to gaps in the literature on peer review that must be addressed in future research. I conclude by building off of the work of Avin in moving toward a more holistic evaluation of funding-by-lottery. Specifically, I consider implications funding-by-lottery variants may have regarding trust and social responsibility.

How is Inclusiveness in Health Systems Research Priority-Setting Affected When Community Organizations Lead the Process?

Community engagement is gaining prominence in health research. But communities rarely have a say in the agendas or conduct of the very health research projects that aim to help them. One way thought to achieve greater inclusion for communities throughout health research projects, including during priority-setting, is for researchers to partner with community organizations (COs). This paper provides initial empirical evidence as to the complexities such partnerships bring to priority-setting practice. Case study research was undertaken on a three-stage CO-led priority-setting process for health systems research. The CO was the Zilla Budakattu Girijana Abhivrudhhi Sangha, a district-level community development organization representing the Soliga people in Karnataka, India. Data on the priority-setting process was collected in 2018 and 2019 through in-depth interviews with researchers, Sangha leaders, and field investigators from the Soliga community who collected data as part of the priority-setting process. Direct observation and document collection were also performed, and data from all three sources were thematically analyzed. The case study demonstrates that, when COs lead health research priority-setting, their strengths and weaknesses in terms of representation and voice will affect inclusion at each stage of the priority-setting process. CO strengths can deepen inclusion by the CO and its wider community. CO weaknesses can create limitations for inclusion if not mitigated, exacerbating or reinforcing the very hierarchies that impede the achievement of improved health outcomes, e.g. exclusion of women in decision making processes related to their health. Based on these findings, recommendations are made to support inclusive CO-led health research priority-setting processes.

Achieving inclusive research priority-setting: what do people with lived experience and the public think is essential?

Background

Engagement of people with lived experience and members of the public is an ethically and scientifically essential component of health research. Authentic engagement means they are involved as full partners in research projects. Yet engagement as partnership is uncommon in practice, especially during priority-setting for research projects. What is needed for agenda-setting to be shared by researchers and people with lived experience and/or members of the public (or organisations representing them)? At present, little ethical guidance exists on this matter, particularly that which has been informed by the perspectives of people with lived experience and members of the public. This article provides initial evidence about what they think are essential foundations and barriers to shared decision-making in health research priority-setting and health research more broadly.

Methods

An exploratory, qualitative study was conducted in 2019. 22 semi-structured interviews were performed with key informants from the UK and Australia.

Results

Three main types of foundations were thought to be essential to have in place before shared decision-making can occur in health research priority-setting: relational, environmental, and personal. Collectively, the three types of foundations addressed many (but not all) of the barriers to power sharing identified by interviewees.

Conclusions

Based on study findings, suggestions are made for what researchers, engagement practitioners, research institutions, and funders should do in their policy and practice to support meaningful engagement. Finally, key international research ethics guidelines on community engagement are considered in light of study findings.

Effectiveness of health consumer representative involvement in implementation of interventions to change health professional behaviour

BACKGROUND

The adoption of research evidence to improve client outcomes may be enhanced using the principles of implementation science. This systematic review aimed to understand the effect of involving consumers to change health professional behaviours and practices. The barriers and enablers to consumer engagement will also be examined.

METHODS

We searched Medline, CINAHL, Embase, the Cochrane Central Register of Controlled Trials and PDQ-Evidence from 2004 to February 2019. Implementation studies involving consumers in at least one phase (development, intervention or facilitation) of an intervention that aimed to change health professional behaviour to align with evidence-based practice were included. Studies in the areas of paediatrics and primary care were excluded. Two review authors independently screened studies for inclusion, and one author extracted data and conducted quality assessments with review of a second author. Knowledge translation interventions were categorized using the Effective Practice and Organisation of Care taxonomy. The primary outcome was measures of change in health professional behaviour.

RESULTS

Sixteen articles met the inclusion criteria. Meta-analysis of three studies found support for consumer involvement in changing healthcare professionals' behaviour (Hedges' g = 0.41, 95% CI [0.27, 0.57], P < 0.001). Most knowledge translation studies involved consumers during the development phase only (n = 12). Most studies (n = 9) included one type of knowledge translation intervention. Professional interventions (including education of health professionals, educational outreach, and audit and feedback) were described in 13 studies.

CONCLUSIONS

Consumer involvement rarely moves beyond the design phase of knowledge translation research in healthcare settings. Further research of the barriers to and effect of increased consumer engagement across all stages of knowledge translation interventions is needed.

The impact of public involvement in health research: what are we measuring? Why are we measuring it? Should we stop measuring it?

As public involvement in the design, conduct and dissemination of health research has become an expected norm and firmly enshrined in policy, interest in measuring its impact has also grown. Despite a drive to assess the impact of public involvement, and a growing body of studies attempting to do just this, a number of questions have been largely ignored. This commentary addresses these omissions: What is the impact of all this focus on measuring impact? How is the language of impact shaping the debate about, and the practice of, public involvement in health research? And how have shifting conceptualisations of public involvement in health research shaped, and been shaped by, the way we think about and measure impact? We argue that the focus on impact risks distorting how public involvement in health research is conceptualised and practised, blinding us to possible negative impacts. We call for a critical research agenda for public involvement that [a] considers public involvement not as an instrumental intervention but a social practice of dialogue and learning between researchers and the public; [b] explores how power relations play out in the context of public involvement in health research, what empowerment means and whose interests are served by it, and [c] asks questions about possible harms as well as benefits of public involvement, and whether the language of impact is helpful or not.

Towards inclusive priority-setting for global health research projects: recommendations for sharing power with communities

Global health research priority-setting is dominated by funders and researchers, often from high-income countries. Engaging communities that are considered disadvantaged and marginalized in priority-setting is essential to making their voices and concerns visible in global health research projects' topics and questions. However, without attention to power dynamics, their engagement can often lead to presence without voice and voice without influence. Global health research priority-setting must be designed to share power with such communities to ensure that research projects' topics and questions reflect the health care and system inequities they face. To better understand what sharing 'power over' priority-setting requires, 29 in-depth, semi-structured interviews and one focus group were undertaken with researchers, ethicists, community engagement practitioners and community-based organization staff. The study shows that, before moving ahead with priority-setting for global health research projects, it is vital to assess whether contextual factors necessary for meaningful engagement between researchers and marginalized communities are present or can be built in the research setting. Study findings describe several such contextual factors and 12 features of priority-setting that affect how processes are run, who participates in them, and who influences their outputs. During priority-setting for global health research projects, it is essential to implement ways of sharing power with communities in relation to these features. Study findings describe a multitude of such strategies that are employed in practice. After priority-setting, it is important to demonstrate respect and accountability to communities.

Social Justice and the Ethical Goals of Community Engagement in Global Health Research

Social justice has been identified as a foundational moral commitment for global health research ethics. Yet what a commitment to social justice means for community engagement in such research has not been critically examined. This paper draws on the rich social justice literature from political philosophy to explore the normative question: What should the ethical goals of community engagement be if it is to help connect global health research to social justice? Five ethical goals for community engagement are proposed that promote well-being, agency, and self-development, particularly for those considered disadvantaged and marginalized. The paper also considers how key terms used in the proposed goals should be defined using existing theories of health and social justice. This analysis is done to give global health researchers and their partners a better idea of what the ethical goals mean. Patterns of convergence amongst different theories are identified that support relying on particular definitions of key terms.

Patient participation in research funding: an overview of when, why and how amongst Dutch health funds

BACKGROUND

Patient participation in decision-making on health-related research has gained ground. Nineteen Dutch health-related research-funding organisations (HFs) have taken up the challenge to include patients in their funding process. A 'Patient participation (PP) advisory team' was set-up, with HF-representatives and patient advocates, who together initiated this study. We provide an overview of when, why, and how PP activities take place in HFs' funding processes, share main challenges and identify possible solutions.

METHODS

A qualitative research design was used. Data was gathered by questionnaires (n = 14) and semi-structured interviews (n = 18) with HF employees responsible for patient participation, followed by a workshop (n = 27) with involved employees of HFs and key players in PP from national patient organisations and research organisations. A descriptive analysis was used for the questionnaire. A semi-directed content analysis was used for the interviews and the workshop.

RESULTS

Three stages can be identified in the funding process in which HFs carry out PP activities: (1) strategic decision-making about focus of research (e.g. shared research agendas); (2) call for and receipt of research proposals (e.g. mandatory inclusion of letter of recommendation from patient organisation); (3) decision-making about the funding of research proposals (e.g. patients reside in a patient panel to co-review research proposals). Main challenges identified to carry out PP activities include: how to accommodate diversity of the patient body (mainly encountered in stage 1 and 3); to what extent should patients receive training to successfully participate (mainly encountered in stage 1 and 3); and who is responsible for patient-researcher dialogues (mainly encountered in stage 1 and 2). All nineteen HFs agree that patients should be included in at least one stage of the funding process for health-related research. CONCLUSION: Further broadening and optimising patient involvement is still needed. The proposed solutions to the identified challenges could serve as inspiration for national and international research funding foundations that aim to structurally include patients in their funding process.

Public involvement and health research system governance: a qualitative study

BACKGROUND

Interest in public involvement in health research projects has led to increased attention on the coordination of public involvement through research organisations, networks and whole systems. We draw on previous work using the 'health research system' framework to explore organisational actors and stewardship functions relevant to governance for public involvement.

METHODS

To inform efforts in Ontario, Canada, to mobilise public involvement across the provincial health research enterprise, we conducted an exploratory, qualitative descriptive study of efforts in two jurisdictions (England, United Kingdom, and Alberta, Canada) where there were active policy efforts to support public involvement, alongside jurisdiction-wide efforts to mobilise health research. Focusing on the efforts of public sector organisations with responsibility for funding health research, enabling public involvement, and using research results, we conducted in-depth, semi-structured interviews with 26 expert informants and used a qualitative thematic approach to explore how the involvement of publics in health research has been embedded and supported.

RESULTS

We identified three sets of common issues in efforts to advance public involvement. First, the initial aim to embed public involvement leveraged efforts to build self-conscious research 'systems', and mobilised policy guidance, direction, investment and infrastructure. Second, efforts to sustain public involvement aimed to deepen involvement activity and tackle diversity limitations, while managing the challenges of influencing research priorities and forging common purpose on the evaluation of public involvement. Finally, public involvement was itself an influential force, with the potential to reinforce - or complicate - the ties that link actors within research systems, and to support - or constrain - the research system's capacity to serve and strengthen health systems.

CONCLUSIONS

Despite differences in the two jurisdictions analysed and in the organisation of public involvement within them, the supporters and stewards of public involvement sought to leverage research systems to advance public involvement, anticipated similar opportunities for improvement in involvement processes and identified similar challenges for future involvement activities. This suggests the value of a health research system framework in governance for public involvement, and the importance of public involvement for the success of health research systems and the health systems they aim to serve.

Public involvement in health research systems: a governance framework

Background

Growing interest in public involvement in health research has led to organisational and policy change. Additionally, an emerging body of policy-oriented scholarship has begun to identify the organisational and network arrangements that shape public involvement activity. Such developments suggest the need to clearly conceptualise and characterise public involvement in health research in terms of governance.

Methods

We drew on an established health research system framework to analyse governance functions related to public involvement, adapting scoping review methods to identify evidence from a corpus of journal papers and policy reports. We drew on the logics of aggregation and top down configuration, using a qualitative interpretive approach to combine and link findings from different studies into framework categories.

Results

We identified a total of 32 scholarly papers and 13 policy reports (n = 45 included papers) with relevance to governance for public involvement. Included papers were broadly consonant in identifying the need for activity to specify and support public involvement across all four governance functions of stewardship, financing, creating and sustaining resources, and research production and use. However, different visions for public involvement, and the activity required to implement it and achieve impact, were particularly evident with respect to the stewardship function, which seeks to set overall directions for research while addressing the potentially competing demands of a system’s many constituents.

Conclusions

A governance perspective has considerable value for public involvement in health research systems, supporting efforts to coordinate and institutionalise the burgeoning public involvement enterprise. Furthermore, it highlights challenges for what is, ultimately, a highly political intervention, suggesting that diverse publics must be both involved within health research systems and enrolled as governors of them.

How embedded is public involvement in mainstream health research in England a decade after policy implementation? A realist evaluation

Objectives To explore how embedded patient and public involvement is within mainstream health research following two decades of policy-driven work to underpin health research with patient and public involvement in England. Methods Realist evaluation using Normalization Process Theory as a programme theory to understand what enabled patient and public involvement to be embedded as normal practice. Data were collected through a national scoping and survey, and qualitative methods to track patient and public involvement processes and impact over time within 22 nationally funded research projects. Results In research studies that were able to create reciprocal working relationships and to embed patient and public involvement this was contingent on: the purpose of patient and public involvement being clear; public contributors reflecting research end-beneficiaries; researchers understanding the value of patient and public involvement; patient and public involvement opportunities being provided throughout the research and ongoing evaluation of patient and public involvement. Key contested areas included: whether to measure patient and public involvement impact; seeking public contributors to maintain a balance between being research-aware and an outsider standpoint seen as 'authentically' lay; scaling-up patient and public involvement embedded within a research infrastructure rather than risk token presence and whether patient and public involvement can have a place within basic science. Conclusions While patient and public involvement can be well-integrated within all types of research, policy makers should take account of tensions that must be navigated in balancing moral and methodological imperatives.

Involving citizens in priority setting for public health research: Implementation in infection research

BACKGROUND

Public sources fund the majority of UK infection research, but citizens currently have no formal role in resource allocation. To explore the feasibility and willingness of citizens to engage in strategic decision making, we developed and tested a practical tool to capture public priorities for research.

METHOD

A scenario including six infection themes for funding was developed to assess citizen priorities for research funding. This was tested over two days at a university public festival. Votes were cast anonymously along with rationale for selection. The scenario was then implemented during a three-hour focus group exploring views on engagement in strategic decisions and in-depth evaluation of the tool.

RESULTS

188/491(38%) prioritized funding research into drug-resistant infections followed by emerging infections(18%). Results were similar between both days. Focus groups contained a total of 20 citizens with an equal gender split, range of ethnicities and ages ranging from 18 to >70 years. The tool was perceived as clear with participants able to make informed comparisons. Rationale for funding choices provided by voters and focus group participants are grouped into three major themes: (i) Information processing; (ii) Knowledge of the problem; (iii) Responsibility; and a unique theme within the focus groups (iv) The potential role of citizens in decision making. Divergent perceptions of relevance and confidence of "non-experts" as decision makers were expressed.

CONCLUSION

Voting scenarios can be used to collect, en-masse, citizens' choices and rationale for research priorities. Ensuring adequate levels of citizen information and confidence is important to allow deployment in other formats.

How stakeholder participation can contribute to systematic reviews of complex interventions

Although patient and public involvement in research is a requirement for research funding in many countries, the knowledge base for how to effectively involve people—and evidence of the effectiveness of involvement—is weak. This article describes how methods used in participatory health research were used to involve patients, clients, providers and community health workers across all stages of a realist review. Sustained involvement enabled better identification of the components of the complex intervention of community-based peer support. It also challenged assumptions of how peer support is constructed, leading the review team to question whether the process of designing and implementing interventions has more influence on effectiveness than previously recognised in empirical studies. We conclude with a discussion on when sustained involvement should be used, and the challenges of incorporating it into the traditional researcher-led approach to systematic reviews.

ReseArch with Patient and Public invOlvement: a RealisT evaluation – the RAPPORT study

Background

Patient and public involvement (PPI) is a prerequisite for many funding bodies and NHS research ethics approval. PPI in research is defined as research carried out with or by the public rather than to, about or for them. While the benefits of PPI have been widely discussed, there is a lack of evidence on the impact and outcomes of PPI in research.

Objectives

To determine the types of PPI in funded research, describe key processes, analyse the contextual and temporal dynamics of PPI and explore the experience of PPI in research for all those involved. Mechanisms contributing to the routine incorporation of PPI in the research process were assessed, the impact of PPI on research processes and outcomes evaluated, and barriers and enablers to effective PPI identified.

Design

A three-staged realist evaluation drawing on Normalisation Process Theory to understand how far PPI was embedded within health-care research in six areas: diabetes mellitus, arthritis, cystic fibrosis, dementia, public health and learning disabilities. The first two stages comprised a scoping exercise and online survey to chief investigators to assess current PPI activity. The third stage consisted of case studies tracked over 18 months through interviews and document analysis. The research was conducted in four regions of England.

Participants

Non-commercial studies currently running or completed within the previous 2 years eligible for adoption on the UK Clinical Research Network portfolio. A total of 129 case study participants included researchers and PPI representatives from 22 research studies, and representatives from funding bodies and PPI networks.

Results

In the scoping 51% (n = 92) of studies had evidence of PPI and in the survey 79% (n = 80), with funder requirements and study design the strongest influence on the extent of PPI. There was little transparency about PPI in publicly accessible information. In case studies, context–mechanism–outcome configurations suggested that six salient actions were required for effective PPI. These were a clear purpose, role and structure for PPI; ensuring diversity; whole research team engagement with PPI; mutual understanding and trust between the researchers and lay representatives; ensuring opportunities for PPI throughout the research process; and reflecting on, appraising and evaluating PPI within a research study. PPI models included a ‘one-off’ model with limited PPI, a fully intertwined model in which PPI was fully embedded and an outreach model with lay representatives linking to broader communities. Enabling contexts included funder, topic/design, resources, research host, organisation of PPI and, most importantly, relationships. In some case studies, lack of coherence in defining PPI persisted, with evidence of a dual role of PPI representative/study participant. Evidence of PPI outcomes included changes to study design, improvements to recruitment materials and rates, and dissemination.

Conclusions

Six salient actions were required for effective PPI and were characterised by a shared understanding of moral and methodological purposes of PPI, a key individual co-ordinating PPI, ensuring diversity, a research team positive about PPI input and fully engaged with it, based on relationships that were established and maintained over time, and PPI being evaluated in a proactive and systematic approach. Future work recommendations include exploring the impact of virtual PPI, cost analysis and economic evaluation of the different models of PPI, and a longer-term follow-up study of the outcomes of PPI on research findings and impact on services and clinical practice.
