AI in Health: Approach and Lines of Action

Artificial intelligence in public health must be implemented in an ethical, transparent, and people-centered manner, promoting the responsible use of data and strengthening health systems.

Artificial intelligence has progressively begun to be incorporated into different areas of public health, including data analysis, epidemiological surveillance, process automation, and support for clinical and management decision-making.

Its implementation offers opportunities to strengthen health systems and improve access to information, but it also raises challenges related to transparency, data protection, equity, and human oversight of automated decisions. In this context, PAHO promotes an artificial intelligence approach grounded in ethical principles, scientific evidence, and people-centered digital transformation.

Principles for the use of artificial intelligence in health

The use of artificial intelligence in public health must be guided by ethical and technical principles that maximize its benefits without compromising people’s rights.

People-centered

Prioritize patient safety, quality of care, and respect for people’s rights.

Transparent

Promote algorithms and processes that can be understood, communicated, and evaluated.

Safe and privacy-respecting

Ensure the protection, confidentiality, and security of the data used.

Evidence-based

Rely on trustworthy, reproducible practices subject to external evaluation.

Equitable and non-discriminatory

Consider equality, inclusion, and diversity in the design and use of technologies.

Human-supervised

Incorporate mechanisms for human control and review in automated decision-making processes.

AI components and subfields that can benefit public health

Artificial intelligence is based on different components and subfields that enable data processing, pattern recognition, information interpretation, and prediction generation. These capabilities can be applied across multiple areas of public health.

These include technologies focused on data analysis, understanding human language, process automation, and interaction with people. Their application can strengthen epidemiological surveillance, improve access to information, and support clinical and management decision-making.

Below are some of these components grouped according to their main function, together with examples of their use in public health.

Language Processing and Understanding

  • Predictive modeling for respiratory diseases and other conditions

Artificial intelligence within the framework of digital transformation

Artificial intelligence is part of a broader process of digital transformation in health, which includes strengthening connectivity, interoperability, data governance, and the development of integrated information systems.

In this context, artificial intelligence is recognized as one of the components that can contribute to improving access to information, strengthening decision-making, and optimizing health services, provided that its implementation is supported by ethical frameworks, technical capacities, and appropriate oversight mechanisms.

PAHO promotes this approach through the principles for the digital transformation of the health sector, fostering people-centered, secure, interoperable technologies aimed at strengthening health systems across the Region.

Based on this approach, PAHO supports countries in developing capacities, tools, and frameworks to enable the safe and sustainable implementation of artificial intelligence.
