[Relevance and feasibility of reforms to create a universal health system in ChileRelevância e viabilidade de uma reforma para a criação de um sistema de saúde universal no Chile].

The health system in Chile is well developed, with broad national coverage. However, organizational limitations necessitate urgent structural reform due to a lack of resources and poor performance, with segmentation and inequity. The government's program for 2022-2026 proposes substantial reforms aimed at creating a universal health system.

[Using different indicators of preventable mortality as an approach to measuring health inequalities in Chilean municipalities].

Objectives: To analyze differences in avoidable mortality among communes in Chile, using different indicators as an operational approach to estimating health inequalities.

Methods: Small area variation analysis in a sample of 117 of all 335 Chilean communes that existed in 1992. By using secondary data, we developed and compared some avoidable-mortality indicators, such as potential years of life lost (PYLL), avoidable mortality (AM) (based on background and criteria drawn from the literature), health care avoidable mortality (HCAMR), and life expectancy.
