Meaningful collaboration between patients and technology companies begins with a common vocabulary. This section bridges both worlds — defining the technical language of health AI for patients and caregivers, and grounding the business case for patient engagement in the frameworks that make it measurable for technology partners. When both sides speak the same language, the result is AI that is built better, trusted faster, and adopted more broadly.

Health AI Key Definitions
A 14-page working reference guide produced by the PXI Center (updated May 2026) to help patient organizations, health systems, and technology partners navigate the language of health AI — from core technical terms to lifecycle governance and trustworthiness frameworks.
Executive Framing
Health AI is best understood as a situated care-delivery system rather than a standalone algorithm. A health AI tool includes the model, the data that created and feeds it, the workflow in which it is used, the people accountable for its outputs, the technical integration layer, the governance controls, and the outcomes it changes.
Working definition: Health AI is a machine-based capability used in health, health care, public health, operations, biomedical science, or care delivery to produce predictions, classifications, recommendations, decisions, summaries, generated content, workflow prioritization, or resource-allocation support.
Document Covers

Meaningful Patient Engagement × ROI
For health tech companies, patient engagement is not a compliance checkbox — it is a product differentiator. AI tools built with genuine patient input reach the market faster, earn payer and provider trust more readily, and generate the real-world evidence that regulators increasingly require. PXI gives technology companies structured access to the patient voice, the frameworks to measure its impact, and the credibility of the National Health Council’s patient community.
Key Concepts
Patient Engagement: The active, meaningful involvement of patients, caregivers, and patient representatives in decisions and activities that affect their health care, research, and the development of health technologies. For tech companies, meaningful engagement means patients are in the room during product design — not just in a beta test after the product is built.
Patient Experience Data: Information directly reported by patients about how they feel, function, and what matters most to them in the context of their disease and its treatment. It tells you whether your product solves a problem patients actually have — and whether it creates new burdens they did not ask for.
Patient-Centered Core Impact Set (PC-CIS): A standardized, patient-derived and patient-prioritized list of the most important impacts a disease and its treatments have on a patient’s health and daily life. PC-CIS gives product teams a validated, defensible set of outcomes to build toward — strengthening regulatory submissions and payer value arguments.
