In-Depth Analysis
Overview
The PCDS is likely the most visited website in UK General Practice for dermatology. Its value lies in verification: "I think this is Pityriasis Rosea, let me check the picture on PCDS." It gives GPs the confidence to make a visual diagnosis.
iatroX complements this workflow. Once you have the diagnosis, the challenge becomes management. Dermatology often involves complex "ladders" of treatment (e.g., emollients -> mild steroid -> potent steroid -> calcineurin inhibitor). iatroX excels at retrieving these ladders and guiding the prescribing decision.
The Perfect Workflow
- PCDS: Use the images to confirm the diagnosis is Psoriasis.
- iatroX: Ask, "What is the initial management for plaque psoriasis and when should I refer?" to get the step-by-step plan.
