Nabla vs NextGen Ambient Assist
A NextGen practice can run either of these, because Nabla names NextGen among the 15 record systems it integrates with, which makes this a genuine choice rather than a default. It is also the clearest test of whether a bundled module is worth taking. Nabla holds the only positive randomized efficiency result in this category, a 9.5 percent reduction in time in note in a trial it did not run, and publishes its data lifecycle down to backup expiry. NextGen publishes an undefined accuracy figure of over 90 percent, no product level security attestation of its own, and no bias position, but it is already in the chart, already in the contract and already through your security review. If the documentation programme has to be defended on evidence, take Nabla. If the constraint is procurement effort rather than performance, the module is there.
- The only ambient scribe in this index with a positive randomized result, a 9.5 percent reduction in time in note against control and the only arm in that trial to meet its primary endpoint.
- It publishes its full data lifecycle: audio not stored, no training on user data, a configurable 14 day retention sized around clinician review, and backups expiring seven days later so deletion actually completes.
- Portability. More than 15 record systems named including Epic, Oracle Health, athenahealth, NextGen, Greenway and Altera, so the documentation programme survives a platform change instead of ending with it.
- It writes into the chart with no integration project, because the vendor is the chart. Capture runs through the NextGen mobile app and the note lands directly in the Enterprise record pending provider review.
- One supplier, one contract, one support path. For a practice without an IT function, avoiding a second vendor security review and a separate integration is a real operational saving.
- A stated purpose limitation on the transcript, used only to generate the structured note, with documentation flowing into the record rather than persisting on the device.

The trial cited is Lukac et al, NEJM AI, 26 November 2025, NCT06792890, run in outpatient care at a single academic health system, so it does not establish note quality or performance in other settings. Nabla's free tier is reported not to include a business associate agreement and its published per month pricing was withdrawn during 2026 in favour of a sales motion, so evaluate on the tier you would contract.
NextGen's over 90 percent accuracy claim is published with no definition, denominator or reference standard and cannot be compared with anything, and its trust page describes the certifications of its cloud host rather than the product's. Neither publishes a bias or accent performance statement.
