Data retention describes how long data is stored and what happens after that period. Healthcare AI reviews should check retention for PHI, audio, transcripts, generated notes, logs, prompts, model inputs, support data, and backups.
Retention terms should be reviewed against contracts, policies, legal requirements, and the intended workflow.
Application scenario: In workflow review, this term helps teams map a vendor claim to the care setting, data flow, integration point, user handoff, and oversight step where it applies. Procurement impact: Buyers should evaluate evidence, interoperability effort, security and privacy controls, pricing assumptions, support, and compliance responsibilities before shortlisting or contracting for a tool that depends on this capability.

HHS states that the HIPAA Privacy Rule does not itself set a medical-record retention period and that state law generally governs how long medical records must be retained; PHI must remain protected for as long as a covered entity maintains it, including during disposal. HHS separately explains that documentation required by the HIPAA Security Rule, including specified policies, procedures, actions, activities, and assessments, must generally be retained for six years after the later of creation or last effective date. That six-year documentation rule should not be represented as a universal medical-record retention period. NIST SP 800-88 Rev. 2 defines media sanitization as rendering access to target data infeasible for a given level of effort and recommends an organizational sanitization program with methods and controls based on information sensitivity. FTC business guidance recommends retaining personal information only while there is a legitimate business need and securely disposing of data no longer needed. These sources do not resolve state medical-record, payer, tax, employment, research, litigation-hold, clinical-trial, minor, contractual, or international requirements. Teams must create a jurisdiction- and record-type-specific schedule for source records, designated-record-set data, audio, transcripts, prompts, outputs, annotations, audit and security logs, support tickets, exports, analytics, model-training data, caches, replicas, archives, backups, disaster-recovery copies, and vendor and subprocessors' copies; document the legal and operational basis, owner, start event, duration, exceptions, hold precedence, access, storage tier, deletion method, verification evidence, and restoration behavior for each class; suspend deletion under an authorized hold without silently broadening access; preserve records needed for patient access, correction, safety, investigation, or reproducibility; propagate expiry and deletion to downstream systems; validate cryptographic erasure or other sanitization where appropriate; and monitor orphaned accounts, failed jobs, backup expiry, reappearing data, configuration drift, and vendor attestations.
