Strengthening Health Systems invites submissions that: The core content of the journal is original scientific reports and discussion papers on successes and failures in health system strengthening interventions worldwide, with a focus on identifying lessons that future programme designers and policy makers can learn from, and knowledge gaps to be filled through academic study. In recognition of the fact that success or failure depends on many external factors that may be unrelated to the technical aspects of project design, SHS will publish analyses of the political, social, cultural and economic environment of health systems interventions to further understanding of what works and what does not in specific contexts. Shorter comment articles on issues of controversy or debate in any area of health systems science or intervention are also welcome.
