Use YouTube's own signals

For some health topics, YouTube shows a health sources shelf in search and an information panel under videos from sources it considers authoritative (YouTube Help). YouTube says it identifies those sources with principles from a National Academy of Medicine expert panel: science-based, objective, transparent and accountable (How YouTube Works, National Academy of Medicine).
