3-Tier DDxTIER 2 · mental-health-native

Most likely. Differential to consider. Don't miss.

A differential structure adapted to mental-health practice — including the diagnoses that kill patients when missed (suicide ideation, psychosis onset, bipolar mania).

§01

Why three tiers

Probability is not enough — clinical risk weights matter.

A purely Bayesian DDx ranks the most likely. A clinician also needs to track what would be catastrophic to miss. The third tier is a non-negotiable safety net for low-probability / high-impact diagnoses.

  • Most likely · Highest posterior probability given evidence
  • Differential to consider · Reasonable competitors deserving rule-out
  • Don't miss · Suicide · psychosis · bipolar · medical mimics

§02

Color-coded

Semantic color, not decoration.

Emerald for Most likely, slate for Differential, claret for Don't miss. The same convention used in the clinic portal — coherence between marketing and product.
