Governments in Latin America have also begunestablishing regional, national, and provincialobservatories. Some of the regional observatories providecomparisons of countries in the region in areas such aspublic health, human resources, food security, andnutrition. Regional and national health observatories havebecome important tools for governments and health ministriesto support national strategic partnerships and to empowercivil society, health sector stakeholders, and health sectorauthorities seeking to develop more effective and efficienthealth systems. Health observatories are therefore a keyinstrument for health systems to generate information, data,and intelligence on people's health status and the typeand quality of health care delivery. By making all thisinformation available to health providers and policy makersin a timely manner, the health observatories will ensurethat their national health systems are results-oriented andengaged in a continuous process of improving quality and access.
