Using Systems Thinking to train future leaders in global health.

Systems Thinking provides a useful set of concepts and tools that can be used to train students to be effective and innovative global health leaders in an ever-changing and often chaotic world. This paper describes an experiential, multi-disciplinary curriculum that uses Systems Thinking to frame and analyse global health policies and practices. The curriculum uses case studies and hands-on activities to deepen students' understanding of the following concepts: complex adaptive systems, dynamic complexity, inter-relationships, feedback loops, policy resistance, mental models, boundary critique, leverage points, and multi-disciplinary, multi-sectoral, and multi-stakeholder thinking and action.

Creating access to health technologies in poor countries.

Many people in developing countries lack access to health technologies. We present seven findings about processes that shape access, based on analysis of six case histories: praziquantel to treat schistosomiasis (a parasitic worm disease), hepatitis B vaccine, the Norplant contraceptive, malaria rapid diagnostic tests, vaccine vial monitors, and the female condom. Each case study is assessed with a comprehensive framework that examines the effects of architecture, availability, affordability, and adoption on creating access.
