MedLog also builds on EHR audit logs. EHRs often maintain event or audit logs for record access. These logs demonstrate that event-level logging in healthcare is feasible at scale: audit logs can capture time-stamped user actions, measure clinical work, and reveal aspects of care delivery that are not visible from clinical or claims data alone.

What audit log research has shown

Workflow efficiency

Audit logs have been used to assess hospital workflow efficiency.

Care patterns

Interaction patterns in audit logs have been associated with length of stay and timeliness of care.

Outlier detection

Audit logs support detection of clinical outliers.

Provider behavior

Audit logs have been used to study provider behavior directly.
Audit logs have also revealed contextual factors relevant to clinical process outcomes across multiple sites, even despite site-dependent documentation differences.

​
Why this matters for MedLog

These past studies of EHR auditing and logging can provide learnings for real-world deployment of MedLog beyond the pilots reported in the MedLog paper. They establish both the feasibility of health-system-scale event logging and the analytic value of linking time-stamped events to care delivery. MedLog Outcomes may themselves include traces of how patients or clinicians interact with the EHR after viewing AI outputs, as recorded in EHR audit logs.
