title: 'From Ambient Documentation to Clinical Intelligence — Chaitanya Asawa, Abridge'
description: >-
  Clinicians call it pajama time: the roughly two hours a day spent writing
  visit notes after work has finished. Abridge started there, and within two to
  three years the documentation product alone reached 300 of the largest health
  systems in the United States. Chaitanya Asawa's framing is that everything in
  healthcare sits downstream of a single conversation between a doctor and a
  patient, and that the administrative machinery got built around that
  conversation rather than out of it. The notes are high stakes in both
  directions. They are the basis of billing, and they are the context the next
  clinician inherits. The engineering problem he stays with longest is
  evaluation, because clinical decision support leaves almost no gap between
  generating an answer and checking one. Sudoku is hard to solve and trivial to
  verify. Here, a verifier good enough to trust would already be your generator.
  Their approach abandons the idea of a single correct answer, since many
  different responses can be right. Two physicians independently write rubrics
  describing the elements a good response should contain, a third adjudicates
  those into one rubric, a fourth runs quality assurance, and only then does a
  judge score responses against those elements. Separate judges cover safety,
  adversarial boundaries and tone. On cost, at a run rate near 100 million
  medical conversations a year, they decompose the note into its sections and
  post train smaller models per section rather than running frontier
  intelligence over everything, betting that a dataset nobody else holds plus a
  narrow enough problem can outrun the frontier's rate of change. Speaker info:
