Abstract
World health care expenditures exceed US $4 trillion. However, there is marked variation in global health care spending, from upwards of US $7,000 per capita in the US to under US $25 per capita in most of sub-Saharan Africa. In developed countries, care of the critically ill comprises a large proportion of health care spending; however, in developing countries, with a greater burden of both illness and critical illness, there is little infrastructure to provide care for these patients. There is sparse research to inform the needs of critically ill patients, but often basic requirements such as trained personnel, medications, oxygen, diagnostic and therapeutic equipment, reliable power supply, and safe transportation are unavailable. Why should this be a focus of intensivists of the developed world? Nearly all of those dying in developing countries would be our patients without the accident of latitude. Tailored to the needs of the region, the provision of critical care has a role, even in the context of limited preventive and primary care. Internationally and locally driven solutions are needed. We can help by recognizing the '10/90 gap' that is pervasive within global health care and our profession by educating ourselves of needs, contacting and collaborating with colleagues in the developing world, and advocating that our professional societies and funding agencies consider an increasingly global perspective in education and research.
