A national case-retrieval engine for acute poisoning management

As a new case is entered, ToxMatch compares it against the national registry and retrieves the most comparable historical cases — each shown with its full management trajectory and final outcome. Decisions are grounded in real, local precedent rather than generic international references.

The problem

A frequent, time-critical emergency

Acute poisoning is a common presentation in Malaysian emergency departments — and one where the first decisions strongly influence the outcome. The treating clinician often has minutes, not hours.

The gap

Data that never reaches the next patient

          Case entered→Stored in registry→never reused
        

There is no rapid way to ask the most useful question: what happened to patients like this one — and how were they managed?

How it works

A new case finds its precedents

STEP 01

Enter the case

Key clinical features are entered as the patient is assessed — agent, vitals, labs, route.

STEP 02

Score similarity

Each registry case is scored against the entry using a weighted clinical feature vector.

STEP 03

Retrieve precedents

The top matching cases are surfaced — ranked by clinical similarity, not recency.

STEP 04

Review trajectories

Each result shows the full management course and outcome of that real case.

247

Registry cases

Drawn from the national pesticide-poisoning registry — paraquat-dense, expanding to other agents.

15+

Clinical features

Weighted similarity across agent, vitals, labs, route, and time-to-contact.

100%

Deterministic

No machine learning, no black-box predictions. Every match is explainable from first principles.

Matching logic

The clinical feature vector

Similarity is computed over explicit features — every match shows why it was selected. No opaque predictive model is involved.
