Raising the Profile of Participatory Action Research at the 2010 Global Symposium on Health Systems Research

By involving citizens and health workers in producing evidence and learning, participatory action research has potential to organize community evidence, stimulate action, and challenge the marginalization that undermines achievement of universal health coverage. This paper summarizes and analyzes results of two sessions on this research model convened by the authors at the First Global Symposium on Health Systems Research in Montreux Switzerland, November 16-19, 2010. In so doing, it reviews case studies and experiences discussed, particularly their contribution to universal health coverage in different settings. The paper also reflects on challenges faced by participatory action research, and outlines recommendations from the two sessions, including creation of a learning network for participatory action research.


BACKGROUND
A universal health system values and ensures the right to health care, entitling all citizens in a country to access the same range of services according to their need and pay for these services according to their income.Knowledge of how to fi nance, organize, and manage health systems is necessary, but not suffi cient, for achieving universal coverage.The systemic processes that produce marginalization and inequality also need to be made visible, understood, and challenged.This includes understanding how health systems as complex social systems refl ect and affect social values, and are capable of exacerbating or reducing inequity.[1] The resulting knowledge can be used to inform public health policy, and at the same time may infl uence the political processes that shape policy and interventions.
Through the collection, analysis, and interpretation of evidence, health systems research (HSR) is one source of new knowledge to inform pathways and policies for attaining universal coverage.Given the many dimensions of health systems, HSR uses multidisciplinary approaches drawn from public health, health economics, and behavioral and social sciences.[2] Participatory action research (PAR) changes the traditional research paradigm to transform the role of those usually participating as the subjects of research, to involve them instead as active researchers and agents of change.[3,4] PAR methods systematize local experience and organize shared collective analysis on relationships and causes of problems.PAR links such analysis to refl ection and action, organizing shared experience and perception to generate new learning and knowledge.In so doing it can strengthen the connection between public actors and the political forces shaping public policy.By involving citizens and health workers in the production of evidence and learning, it can strengthen the legitimacy of research fi ndings and challenge disabling power imbalances that undermine policies aimed at achieving universal health coverage.[3][4][5][6] In their work on PAR, Minkler and Wallerstein describe its use to study a range of health systems issues-from action on social determinants of health, through community health outreach, to improving quality of services.[3] As with other areas of research, PAR has limitations and challenges, both in design and application.The methods are not well known by practitioners mostly acquainted with more conventional public health research approaches.The work takes time to build trust and allow for involvement, discussion, and refl ection by communities; and it requires mentoring to support facilitation skills.The core method for knowledge production-collective validation by homogenous groups-often is not applied rigorously.[7,8] Findings are specifi c to particular communities and sites, limiting possibilities for meta-analysis across PAR sites.This affects scale and generalizability of fi ndings, the latter requiring triangulation with other sources of evidence, such as results of quantitative surveys or health information systems.Furthermore, empowerment and dialogue are not automatic outcomes of PAR.[6,9] PAR fi ndings often point to structural determinants demanding action at higher levels of authority than those found within communities.These diffi culties raise issues for how to institutionalize participatory research and practice.

Participatory Action Research (PAR) seeks to understand and improve the world by changing it. At its heart is collective, self refl ective inquiry that researchers and participants undertake, so they can understand and improve upon the practices in which they participate and the situations in which they fi nd themselves. The refl ective process is directly linked to action, infl uenced by understanding of history, culture, and local context and embedded in social relationships. PAR uses and systematises learning based on experience to build knowledge that infl uences practice. The process of PAR should lead to people having increased control over their lives…PAR draws on the paradigms of critical theory and constructivism and may use a range of qualitative and quantitative methods.
Baum et al. [4] Peer Reviewed Guatemala, India, East and Southern Africa, and Canada presented their experiences using PAR approaches in HSR.This was followed by a marketplace in which approximately 50 delegates raised and debated key points on PAR's unique contributions to achieving universal coverage in health systems; the reasons for PAR's low profi le and infrequent use in building health system knowledge; and recommendations for the Symposium.
In a follow-up session, the authors presented the major issues raised in the marketplace discussions, and delegates briefl y presented and exchanged their own PAR experiences.Delegates referred to presentations and discussions from both sessions to draw conclusions on implications for future participatory research on health systems and for follow-up action to build a PAR learning network.[

East and Southern Africa: Strengthening people-centered health systems
A learning network and 'pra4equity' listserv (pra4equity@ equinetafrica.org)provided a communication channel for exchange and dialogue across 19 sites in 7 countries implementing PAR on areas of common focus, to examine the interface between communities and health systems using shared design and tools.Three individual studies from Zambia, South Africa, and Democratic Republic of the Congo reported on local problems identifi ed and addressed.The common methods and learning network facilitated collective validation of barriers to universal health coverage.Results showed that communities prioritize causes of ill health at a more structural level than health workers.Health services were found to have high legitimacy but low capabilities for social roles.The results showed that failing to address these social barriers to uptake can lead to wasted resources in health services-for example, through poor adherence to treatment-and also to vicious cycles of ill health in communities.[15][16][17][18] Canada: PAR within a movement for universal health coverage Work on community health centers located PAR within the context of a wider movement for universal coverage initiated in 1962 and advanced in the following three decades.[19] The presence of community-elected boards in local health centers facilitated raising research questions from the community.[20] As a result, PAR provided evidence to support development of a community health center for poor women, and evidence on medication needs and patterns of use that motivated development of an essential drugs list.The PAR approach provided a means to draw on the community and ensure that new learning was organized and known within the community.

DISCUSSING EXPERIENCES OF PAR AND ITS RELEVANCE TO HEALTH SYSTEMS
The two sessions highlighted that there is a rich experience in PAR, and far more practice taking place than is being published.Delegates proposed usefulness of documenting and systematizing case studies of PAR in HSR.
Case examples presented from different continents all indicated that PAR approaches can enhance communication within health systems and among health personnel, communities, and others; as well as enhance mutual respect among these different groups for their respective experience and roles.PAR provides a means for recognition and early detection of health problems that may be unrecognized-including chronic diseases in communities, work-related health problems among health workers, and those related to social determinants of health.PAR methods encourage sharing of analysis and power between primary care health workers and communities, to the benefi t of both.The PAR process builds cycles of learning, refl ection, and action; and stimulates communities and local levels of health systems to develop and implement locally determined plans.
In the marketplace session discussion, delegates raised twelve further examples of PAR work in South Africa, India, Lesotho, Zambia, Malawi, Zimbabwe, Egypt, Argentina, Venezuela, Cambodia, and in multi-site international studies.These experiences provided examples where PAR has elicited community values, identifi ed community assets for health, and built understanding of social and systemic barriers to health care coverage.As in studies presented in the fi rst session, those described by delegates were often implemented with vulnerable communities, such as commercial sex workers or users of harmful drugs.PAR was found to be an effective way of organizing community evidence and perceptions to improve health system functioning, especially when fi ndings were triangulated with evidence from other sources.
Various methods were described.Some involved community members in data collection, using traditional tools such as questionnaires; others used report cards and checklists to document community perceptions and experiences; while others used tools to facilitate more collective processes for raising, organizing, and interpreting evidence; e.g., ranking and scoring methods and social mapping.Health authorities or trade unions with structures from community to national levels were reported to have facilitated

Perspective
Peer Reviewed use of evidence from community level inquiry at sub-national and national levels, or to have assisted in scale-up of intensive community-based PAR processes to new levels and regions.Some case studies had institutionalized participatory approaches within health systems; participants noted that this required support in early stages from health authorities as well as mentoring and resource support for those involved.
Delegates' observations on limitations of PAR in building health systems Delegates observed that PAR's contribution is limited by the following factors: • PAR may be perceived as an inferior approach to research, or "not real science."This view is reinforced by the fact that PAR is not taught in medical or health science courses.It also refl ects a tendency to discount knowledge held by communities; • It is diffi cult to test PAR methods using traditional scientifi c criteria, due to reliance on subjective evidence, different approaches to validating knowledge and diffi culties generalizing from specifi c sites; • PAR raises demands for implementation, requiring time, people, patience, and resources.These demands and the fact that outcomes are not predictable may discourage funders; and • There are diffi culties moving from local experience and knowledge to national health systems, limiting the scale and impact of PAR and its ability to challenge inequities in power at higher levels.
Delegates' conclusions on PAR's unique contribution to achieving universal health coverage Delegates were in agreement that PAR contributes to this goal through the following approaches and mechanisms: • Providing conditions and processes that encourage social empowerment, by strengthening collective power in affected communities (including health workers); confronting and changing power dynamics that perpetuate inequities; building shared understanding of conditions and their causes; and providing a means for people to articulate their thoughts and experience and demand needed health inputs and services; • Increasing potential to strengthen local levels of health systems, through generating and promoting use of local-level evidence, supporting ownership and involvement of people in health systems, and enhancing dialogue between health workers and communities; • Organizing demands for services prioritized by communities; and • Linking knowledge generation to its use in action.

Delegates' recommendations for tapping PAR potential and addressing challenges of PAR in Health Systems Research-Delegates recommended:
• Making clearer links between PAR and the health equity and social determinants of health agenda, recognizing communities as best placed to identify and act on issues related to social determinants of health; • Embedding PAR methods within routine health system planning, implementation, and evaluation, such as through community monitoring of quality of care; • a communication channel through a listserv; • a website portal providing resources and links to members websites; • a repository of resources, photos, case studies, and methods; • an inventory of institutions working with PAR; and • opportunities for face-to-face meeting and exchange of evidence, methods, and lessons learned.
Initially, as an interim tool for shared communication and to widen involvement in follow-up to this discussion, the pra4equity listserv already set up in East and Southern Africa [pra4equity@ equinetafrica.org] was widened to subscribe people from other regions.
Strengthening PAR approaches in HSR is also part and parcel of wider efforts aimed at building greater constituency, credibility, and capacity for HSR globally.[21] This was refl ected in the closing plenary session of the Global Symposium on HSR, when Etiayo Lambo, Nigeria's former Minister of Health, called for any strengthening of HSR to involve the policy and practice communities in the research process, especially in data gathering and analysis, "using problem-solving, action-oriented approaches like operations research and participatory action research."[22]  For conference delegate support, we extend our thanks to conference organizers, the Open Society Foundation, and the Doris Duke Foundation; and many thanks as well to delegates who contributed to discussions reported in this article.
