Health policy and systems research: the
future of the field
David H. Peters
  Abstract
  Health policy and systems research (HPSR) has changed considerably over the last 20 years, but its main purpose
  remains to inform and influence health policies and systems. Whereas goals that underpin health systems have
  endured – such as a focus on health equity – contexts and priorities change, research methods progress, and
  health organisations continue to learn and adapt, in part by using HPSR. For HPSR to remain relevant, its
  practitioners need to re-think how health systems are conceptualised, to keep up with rapid changes in how
  we diagnose and manage disease and use information, and consider factors affecting people’s health that go
  well beyond healthcare systems. The Sustainable Development Goals (SDGs) represent a shifting paradigm in
  human development by seeking convergence across sectors. They also offer an opportunity for HPSR to play
  a larger role, given its pioneering work on applying systems thinking to health, its focus on health equity,
  and the strength of its multi-disciplinary approaches that make it a good fit for the SDG era.
  Globally, population health is being challenged in different ways, from climate change and growing air pollution
  and toxic environmental exposure to food insecurity, massive population migration and refugee crises, to
  emerging and re-emerging diseases. Each of these trends reinforce each other and concentrate their harms
  on the most vulnerable populations. Multi-level governance, together with novel regulatory strategies and
  socially oriented investments, are key to successful action against many of the new challenges, with HPSR
  guiding their design and evolution.
  The HPSR community cannot be complacent about its successful, yet short, history. Tensions remain about
  how different stakeholders use HPSR such as the contrast between embedding research within government
  institutions versus independently evaluating and holding decision-makers accountable. Such tensions are inevitable in
  the boundary-spanning field that HPSR has become. We should strive to enhance the influence of HPSR by staying
  relevant in a changing world and embracing the strength of our diversity of disciplines, the range of problems
  addressed, and the opportunity of the SDGs to ensure that health and social benefits are more inclusive for
  people within and across countries.
