What it is
Aide is a clinical guideline retrieval platform for Emergency Departments. It lets any clinician — consultant, registrar, locum on their first shift — ask plain-English questions and get source-cited answers from locally uploaded protocols, pathways, and logistical information. Where is the difficult airway trolley? What’s our sepsis pathway? Who do I call for a paediatric head injury? Aide retrieves what the department has already decided is correct, and presents it in seconds. It does not triage, diagnose, or recommend treatment.
Why I built it
On a busy night shift, a foundation doctor asked me which sepsis pathway to follow for a deteriorating patient — our Trust protocol or the NICE guideline they’d found online. Our local protocol was buried three clicks deep on the intranet, last updated eighteen months ago, and the search returned forty irrelevant results. We got it right because I knew where to look. A locum on their first shift would not have. This repeats daily across London. It is not a knowledge gap — it is an access gap, with real consequences for patient safety.
What I did
Designed and built the platform single-handedly in React 19 with Convex as the real-time database and an LLM-based retrieval-augmented generation agent. Automated PDF and DOCX ingestion into a standardised knowledge base. Source-cited answers with confidence scoring. Built-in clinician feedback on every response. Usage analytics and full audit trail. Administrators update content through the UI — no IT tickets, no version hell.
Where it’s at
Deployed on production infrastructure. Currently testing with clinical lead colleagues at Whipps Cross A&E, refining the RAG agent, improving response quality from real ED queries, and building a structured clinician feedback loop to understand what works and what doesn’t.
The next ambition is a formal DCB 0129/0160 clinical safety case and a mixed-methods evaluation framework — the governance work that determines whether a tool like this actually helps in a live department.
