Problem

Clinicians spent hours of their own time on notes and letters after consultations.

Approach

The trust piloted four ambient voice products (Accurx Scribe, Tortus, Heidi and Lyrebird) in inpatient and outpatient settings. The tools listen to the consultation and draft the note for the clinician to check. The trust published an evaluation report in February 2026.

Takeaway

Self-reported time savings were large, but more than a third of logged outputs needed editing and 44% of users saw at least one hallucination. The evaluation relies on clinicians' own estimates.
