Before After Scar Analysis

Description

Use this skill to structure a conservative before/after scar comparison for clinical documentation, research preparation, or clinician review. It integrates photo-quality limitations, symptom change, treatment exposure, and follow-up timing. It does not independently determine recurrence or treatment success.

When to Use

A scar or keloid has baseline and follow-up images.
A clinician needs a cautious comparison note.
A registry needs outcome-supporting observations without overstated claims.
Marketing or teaching language needs bias controls.

Do Not Use

Do not compare images with severe lighting, angle, focus, or timing confounders without stating limitations.
Do not claim cure, guaranteed response, or recurrence status without clinician review.
Do not use for emergency complications without escalation.
Do not edit images to exaggerate differences.

Required Inputs

Baseline and follow-up image quality notes, ideally from scar-image-quality-review.
Visit offsets or follow-up interval.
Treatment exposure between visits.
Patient-reported symptoms if available.
Clinician observations or validated scale scores if available.

Workflow

Confirm that both timepoints are de-identified or handled under approved clinical storage.
Summarize interval and treatment exposure.
Review comparability:
- lighting
- angle
- focus
- scale marker
- color reference
- edema, makeup, posture, or clothing confounders
Describe visible changes conservatively:
- contour or height
- erythema or pigmentation
- boundary or spread
- surface texture
- surrounding skin
Integrate symptoms and scale scores separately from image observations.
Draft outcome-supporting language without final clinical claims.
List missing information needed before a registry outcome.csv label is assigned.

Output Format

Comparison readiness
Interval and treatment context
Image quality and confounders
Region-by-region observations
Symptom and scale-score changes
Conservative outcome-supporting statement
Missing information and clinician-review questions

Safety and Compliance

This skill supports documentation, research preparation, and clinician review. It does not diagnose, prescribe, determine recurrence, or replace licensed clinical judgment. Escalate urgent symptoms, suspected infection, wound breakdown, severe pain, rapid progression, bleeding, ulceration, or functional compromise to a qualified clinician.

For public-facing use, confirm consent and avoid implying typical results from a single case.

Examples

Compare this synthetic baseline and day-90 anterior chest keloid case and draft conservative outcome-supporting language.

Integration

Works well with scar-image-quality-review, keloid-follow-up-intake, scar-treatment-response-review, and scar-consent-language-review.
