n recent decades, a significant improvement in people’s general health conditions has occurred, leading to an increase in life expectancy at birth in most countries in the Region of the Americas. This progress has been the result of both health technology advances – antibiotics, vaccines, and other treatments – and improvements in the conditions in which people live, including increased access to improved drinking water and sanitation, and health services. Nevertheless, progress has slowed in recent years, and achievements have varied among countries and territories, as well as within them. In the journey toward universal health, it is essential to have the ability to monitor and assess progress in terms of the ultimate goal of health systems: improving the health and well-being of populations. To this end, this edition of Health in the Americas analyzes the standardized rate of potentially avoidable premature mortality as an indicator of health system performance, considering both its preventable component through public and intersectoral health interventions, as well as the treatable component, related to the effectiveness of health services, that is, the quality of health care. The analysis of potentially avoidable premature mortality provides a metric for comparing and tracking performance over time.
