Recording Baseline Severity Across Three Indices
Every index is scored once before therapy begins.
- 0–72: PASI baseline range (higher = more severe)
- 0–72: EASI baseline range (body-region weighted)
- 0–100: VASI baseline range (% body surface affected)
- 3: Indices tracked (PASI / EASI / VASI)
Why score three indices at once
Different conditions need different validated severity scales.
Baseline sets the reference point for every future comparison.
Following Each Index Week by Week
Repeat scoring builds a per-index trend line over time.
- q4wk: Typical follow-up (clinic visit cadence)
- 0–24wk: Course length (induction + maintenance)
- exponential-like: Decay pattern (fastest early response)
- ~6: Data points/course (per index)
Reading a single trend line
A downward slope signals improving disease control.
Slope steepness differs by index and by drug class.
Overlaying All Three Trends on One Timeline
Side-by-side curves reveal which condition responds fastest.
- EASI: Fastest typical responder (in this simulated model)
- VASI: Slowest typical responder (repigmentation is gradual)
- weeks: Comparison axis (shared x-axis across curves)
- % of baseline: Normalization (enables fair comparison)
Why normalize before comparing
Raw scales differ, so percent change enables comparison.
Overlay view flags a lagging index early.
Rolling Up Trends into One Response Marker
A single composite marker summarizes overall treatment response.
- 3 indices: Composite inputs (weighted by condition tracked)
- 4: Response bands (none / partial / major / complete)
- per visit: Update frequency (recalculated live)
- 1 marker: Output (clinician-facing summary)
From three curves to one number
Composite scoring simplifies multi-index monitoring for review.
Composite view speeds up routine treatment check-ins.
Turning Trajectory into a Treatment Decision
Milestones and trajectory jointly inform the next step.
- 2: Decision inputs (milestone + trajectory)
- <50% @ wk16: Escalation trigger (example rule of thumb)
- ≥75% sustained: Maintenance trigger (example rule of thumb)
- 24wk: Review horizon (full course window)
Using the dashboard at point of care
Dashboard view supports faster, more consistent treatment decisions.
Combining indices avoids over-relying on a single score.
