Miruwa watches the gaps between visits.
WhatsApp check-ins, vital signals, and explainable rules help nurses monitor elderly chronic-care patients between clinic visits.
Monitoring support only. Not diagnosis. No treatment recommendation.

The gap between visits
The risk is not only inside the clinic. It is the long period where symptoms, adherence, and daily changes become invisible.
Clinic visit
Patient seen, plan updated.
Long gap
Days to weeks pass with little visibility.
Missed symptoms
Symptoms worsen, signals are missed.
Urgent care
Condition worsens, costs go up, stress rises.
The real bottleneck is adherence,
not only monitoring.
- Elderly patients may not open new apps or remember daily check-ins.
- Families and care teams have limited visibility.
- Delays can lead to avoidable deterioration and urgent care.
How it works
From a WhatsApp message to a nurse decision — four steps, no app for the patient to install.
Patient answers on WhatsApp
A daily Cantonese or English check-in. No app to install, no login to forget.
Signals are structured
Symptoms, weight, blood pressure, and voice notes become structured data.
Deterministic rules evaluate
Explainable rules (HF-001, not a black box) decide what needs attention. No AI diagnosis — ever.
Nurses see exceptions first
An exception-first dashboard with a full audit trail. One nurse covers a whole ward.
One queue. Only the exceptions.
Nurses don't scan 24 patients — Miruwa surfaces the few who need review and says exactly why.
