Aama-AI

An intelligent maternal health companion for rural Nepal

Nepal’s maternal mortality ratio stands at 142 deaths per 100,000 live births — nearly twice the SDG target. The cause is rarely a lack of medicine. It is the absence of any intelligent system that can recognize danger, guide a woman to care, and prepare that care before she arrives.

Aama-AI is a five-module, offline-first AI platform trained on real Nepalese clinical data and deployed through the community health volunteers rural Nepal already trusts.

The Problem

Three delays, one silence

Medical researchers describe preventable maternal death through the Three-Delays Model (Thaddeus & Maine, 1994). In rural Nepal, all three delays operate simultaneously, unaddressed by any existing digital platform.

01

Failure to recognize danger

Without a system to monitor vitals or symptoms, a woman has no way to know whether what she is feeling is ordinary discomfort or a life-threatening warning sign.

02

Failure to reach a capable facility in time

Even when danger is recognized, the nearest hospital is often hours away — and may not be the nearest one equipped to treat the specific emergency.

03

Failure to receive adequate care on arrival

Clinical teams learn of an emergency only when the patient is at the door, leaving no time to prepare staff, blood, or an operating theatre.

Five failures, addressed by nothing at once

  • Obstetric risk is not detected early
  • Clinical triage is unavailable
  • Emergency routing is absent
  • Mental health is invisible
  • Nutritional guidance is generic and inaccessible

Why Existing Solutions Fail

Every approach solves one fragment

Three decades of digital health interventions in Nepal have produced measurable but fragmented results. SMS interventions reach FCHVs but stay passive. Telemedicine helplines resolve cases only when a specialist happens to be available. Government systems report what services were delivered — not who is at risk. No platform has combined offline-first architecture with a maternal risk model trained on Nepalese clinical data. Aama-AI is the first.

The Platform

Five integrated AI modules

Each module reinforces the others, so a woman’s journey from symptom to risk assessment to emergency care is continuous — and available without a doctor physically present.

Module 01Addresses Delay 1

Maternal Risk Prediction

A community health volunteer logs a woman's vitals during a home visit. Within seconds, the model classifies her risk as Low, Moderate, or Severe.

An ensemble of Random Forest and XGBoost, trained on clinical data from a partner Nepalese teaching hospital, classifies risk from blood pressure, weight, temperature, oxygen saturation, haemoglobin, gestational age, and reported symptoms. SHAP explainability shows the volunteer exactly which vital triggered an alert — the model is never a black box. A Severe classification bypasses the chatbot entirely and fires an immediate alert to the doctor portal.

RAG-Constrained Triage Chatbot

A conversational assistant answers symptom questions in Nepali — grounded strictly in verified clinical guidelines, never in open-ended model knowledge.

The chatbot is constrained by Retrieval-Augmented Generation: guidelines from Nepal's Ministry of Health, WHO Nepal, and hospital protocols are chunked, embedded, and stored in a vector database. Every response is retrieved from this verified content, not generated freely, eliminating hallucinated medical advice. Structured intent classification detects danger-sign language and escalates to a human volunteer or doctor.

MCDM Hospital Routing

When an emergency is identified, the platform routes to the nearest hospital actually equipped to treat it — not simply the nearest one.

A TOPSIS multi-criteria decision algorithm scores reachable hospitals against weighted criteria — specialist availability, operating theatre, blood bank, ICU capacity, and distance — using a curated dataset of verified obstetric capability. Routing to a facility that lacks a blood bank or surgical capacity wastes the exact time a severe complication cannot afford.

Mental Health Screening

Perinatal depression and anxiety, affecting over 15% of pregnant women in Nepal, are surfaced through standardized screening — and always escalated, never counselled by the AI.

The chatbot conversationally administers the PHQ-4 and Edinburgh Postnatal Depression Scale (EPDS). A moderate-to-severe score triggers an immediate alert to the doctor portal and notifies the volunteer. The system deliberately stops short of offering counselling itself — its role is detection and escalation to a human professional, not treatment.

Nutrition & Anaemia Guidance

Dietary guidance grounded in foods that actually exist in rural Nepal, tied directly to each woman's haemoglobin trend.

A retrieval-augmented knowledge base delivers guidance using locally available foods — dal bhat, leafy greens, sesame seeds, dried fish, fortified flour — rather than generic dietary advice. Haemoglobin is logged as a vitals field, feeding both this module and the risk prediction model, so anaemia risk directly influences a woman's overall classification.

How It Works

One journey, three interfaces

The five modules operate as a single continuous workflow across three purpose-built interfaces — two of them working entirely without internet, syncing only once a connection is available.

Android · Offline-first

Woman's App

Used directly by pregnant women who own a smartphone — logging vitals, querying the triage chatbot, and receiving risk alerts on their own device.

Android · Offline-first

FCHV App

Carried by Female Community Health Volunteers on their own device. Operated on a woman's behalf during home visits, reaching those without a personal smartphone.

Web · Online

Hospital Admin Portal

Used by doctors and hospital staff over the facility's internet connection — a real-time dashboard of incoming risk alerts, patient history, and emergency routing.

A woman's journey, step by step

  1. 1

    Vitals are logged

    Works offline

    A woman with a smartphone logs her own symptoms and vitals. Where she has none, an FCHV visits and logs the same data on the FCHV app instead.

  2. 2

    Risk is classified instantly

    Works offline

    The risk engine classifies Low, Moderate, or Severe on-device, with no connection required.

  3. 3

    Guidance or emergency routing follows

    Works offline

    Non-severe cases get chatbot guidance grounded in verified clinical guidelines. A Severe classification calculates the nearest hospital with the required obstetric capability, using the last-synced hospital dataset.

  4. 4

    The device reconnects

    Syncs on reconnect

    As soon as the woman's phone or the FCHV's device regains signal, vitals, risk history, and any alerts sync automatically to the cloud backend.

  5. 5

    The hospital sees it first

    Online

    The hospital admin portal updates in real time. Doctors see the risk history and emergency alert before the patient arrives, with time to prepare a theatre, blood, or specialist staff.
