Governance

How do you keep patient data governed when using AI?

Start with the actual data flow and legal roles, then limit purpose, access, retention, locations, and subprocessors. Define authorized-clinician approval for clinical decisions and verify security and audit evidence for the deployment.

Put the evidence in context

Review the intended task, source information, human checkpoints and observed results together. A benchmark or sandbox result has a defined scope; it does not establish suitability, approval or performance for every institution.

Patient-data governance starts before a model is selected. Map what data enters the workflow, where it is processed and stored, who can access it, which party decides each purpose, which subprocessors are involved, and whether data or support access crosses borders. Then apply data minimization, role-based least privilege, purpose limits, authentication, retention and deletion rules, incident handling, and contractual instructions appropriate to that flow.

The AI boundary is equally important. The institution should define what the system may prepare, what an authorized clinician must approve, what non-clinical staff may action, and what must stop or escalate. Audit evidence should cover the high-risk events the institution needs to reconstruct, but logging scope, integrity, export, and retention must be tested for the actual configuration. Data does not necessarily remain in the hospital's own systems, and no single residency or controller-processor model fits every deployment. These points must be confirmed under the applicable law, architecture, and contract before production.

Does using AI mean patient data is used to train a model?+
Not necessarily. Training, evaluation, product improvement, and support use depend on the architecture, provider terms, legal basis, notices or authorizations, and contract. Obtain an explicit written position for the proposed deployment before providing production data.
What should the audit trail capture?+
Start with the high-risk events: data access, AI output, material edits, approval or rejection, release, export, and administrative changes. The institution should also verify identity binding, timestamps, integrity, access, exportability, and retention for the configured system.
