Clinical practice, including internal medicine, draws on a rapidly expanding knowledge base but remains focused on individual patient care; clinical interventions are rarely population-based.

Global Issues in Medicine Part 13 Conclusion Toward a Science of Implementation Public-health strategies draw largely on quantitative methods from epidemiology and biostatistics but also from economics. Clinical practice including internal medicine draws on a rapidly expanding knowledge base but remains focused on individual patient care clinical interventions are rarely population-based. In fact neither public-health nor clinical approaches alone will prove adequate in addressing the problems of global health. There is a long way to go before evidence-based internal medicine is applied effectively among the world s poor. Complex infectious diseases such as AIDS and TB have proven difficult but not impossible to manage drug resistance and a lack of effective health systems have further complicated such work. Beyond communicable disease in the arena of chronic diseases . cardiovascular disease global health is a nascent endeavor. Efforts to address any one of these problems in settings of great scarcity need to be integrated into broader efforts to strengthen failing health systems and to alleviate the growing personnel crisis within these systems. For these reasons scholarly work and practice in the field once known as international health and now often designated global health equity are changing rapidly. Such work is still informed by the tension between clinical practice and population-based interventions between analysis and action. Once metrics are refined how might they inform efforts to lessen the premature morbidity and mortality registered among the world s poor As in the nineteenth century human rights perspectives have proven helpful in turning attention to the problems of the destitute sick such perspectives may also inform strategies of delivering care equitably. A number of university hospitals are developing training programs for physicians with interests in global health. In medical schools across the United States and in other .
