Nabla vs TORTUS
Tortus says it is the first ambient voice product certified as a UKCA Class IIa medical device, holds ISO 13485 and is built to NHS England's standard for ambient voice technology. The NHS England Phase IV evaluation covered nine sites and more than 17,000 patients but was run jointly with Tortus. Tortus reports that St George's emergency department saw patient capacity per shift rise 13.4%. With Epic and Cerner integrations inside NHS trusts, an English trust is its natural customer.
Nabla shows HIPAA, SOC 2 Type 2, ISO 27001 and GDPR on its home page, has a California randomized trial with a 9.5% drop in time in note, and offers a partner API. A US outpatient group needs the HIPAA, SOC 2 and BAA terms that Tortus leaves unstated, so Nabla is the pick there. Tortus sells on quote with no public price, and Nabla bills monthly per user in euros excluding VAT.
