For Bangladesh · Pilot-Ready Digital Health Model

BNHS by Healodex

Bangladesh Networked Healthcare System for Doorstep Care.

A pilot-ready digital healthcare model connecting citizens, Community Health Workers, diagnostics, doctors, specialists, pharmacies, and health records.

Designed to complement Bangladesh's Family / Farmer / Health Cards, Health ID, Shared Health Record, Community Clinics, telemedicine services, DHIS2 reporting needs, and Universal Health Coverage goals.

BNHS is not just an app, not just a device, and not just telemedicine. It is a standards-ready service delivery architecture for last-mile healthcare.

Why Bangladesh Needs This

Primary healthcare access remains uneven across rural, semi-urban, and underserved communities. BNHS is designed as a respectful, complementary layer to strengthen national service delivery.

Rural & Semi-Urban Access Gaps

Many citizens travel long distances for routine check-ups, often delaying or skipping care entirely.

Delayed Diagnosis & Treatment

Limited diagnostics at the local level mean conditions are detected late, raising costs and risks.

Overcrowded Hospitals

Tertiary hospitals absorb cases that could be managed earlier through community-level primary care.

No Continuous Patient History

Without persistent records, every visit starts from zero — undermining continuity and follow-up.

The BNHS Model

A simple, three-pillar service design that meets citizens where they are.

01

Doorstep Care

Community Health Workers visit patients at home with the Healodex Kit, removing distance and mobility barriers.

02

Connected Diagnostics

Vitals, symptoms, and basic clinical data are captured digitally and synced securely to the cloud.

03

Remote Doctor Access

Licensed doctors review patient history and real-time data before issuing consultation, prescription, or referral.

Built to Complement Bangladesh's Digital Health Direction

BNHS by Healodex is designed as a field-level service layer that can strengthen existing and future public digital-health infrastructure. It can support Health ID-based identification, consent-based patient history access, Community Clinic referrals, telemedicine workflows, DHIS2-compatible aggregate reporting, and standards-based interoperability. It is not a replacement for existing systems.

Health ID / NID / BRN Ready

Patient identity lookup and profile creation, subject to approved access.

SHR / HIE Readiness

Designed for consent-based record continuity and future health information exchange.

FHIR R4 Interoperability Layer

Planned HAPI FHIR R4-compatible architecture for structured health data exchange.

DHIS2-Compatible Reporting

Aggregate pilot indicators can be exported for public-health reporting.

Consent & Audit Trail

Every card lookup, prescription, benefit check, referral, and follow-up action is traceable.

Subject to Government Policy

Integrations and data exchange remain subject to government policy, API access, and authorization.

How It Works

From request to follow-up — a clear, auditable patient journey.

Visual overview of the Healodex service flow.
  1. 1

    Request Care

    Patient calls a hotline, uses app/SMS, or requests service through a local point.

  2. 2

    CHW Assignment

    The nearest Community Health Worker receives the assignment and route guidance.

  3. 3

    Home Visit

    CHW visits with the Healodex Kit or approved compatible devices.

  4. 4

    Identification & Consent

    Health ID / NID / BRN / approved card or QR opens or creates the profile with consent.

  5. 5

    Vitals & Symptoms

    Vitals, symptoms, risk factors, and basic clinical data are captured digitally.

  6. 6

    AI-Assisted Triage

    AI flags urgency and suggested pathway, but does not replace clinical judgment.

  7. 7

    GP / Medical Officer Review

    A licensed doctor reviews the case remotely.

  8. 8

    Specialist Referral Layer

    Cases can be escalated to specialists such as pediatrics, maternal health, cardiology, diabetes/NCD, respiratory, or emergency referral.

  9. 9

    Prescription, Pharmacy & Benefit Check

    Digital prescription, medicine availability, benefit eligibility, patient consent, and audit trail.

  10. 10

    Follow-up & Records

    SMS / voice / app reminders and continuous patient history update.

Designed to Complement National Card-Based Service Delivery

BNHS does not replace any government system. It is built to act as a field-level service layer that respects and connects to existing identity and benefit programs.

BNHS can integrate with Health Card, Family Card, Farmer Card, NID, Birth Registration Number, or approved QR-based citizen identification systems. During a home visit, the Community Health Worker can scan the card to quickly open or create a patient profile. This helps preserve medical history, prescriptions, vitals, follow-up records, and referral information across future visits.

For eligible citizens, approved consultation, medicine, or diagnostic support may be connected with government benefit systems subject to policy, API access, and authorization. This can make healthcare delivery more transparent, auditable, and people-friendly.

Clinical Service Modules

BNHS is designed as a modular service model so pilots can start small and expand based on Ministry priorities.

NCD & Chronic Care

Hypertension follow-up, diabetes monitoring, COPD/respiratory tracking, cardiovascular risk screening, medication adherence, and red-flag referral.

Maternal & Child Health

ANC support, maternal BP tracking, child fever/cough/diarrhea triage, immunization reminders, growth/nutrition follow-up, and referral to appropriate facilities.

Elderly & Home-Based Follow-up

Mobility-friendly checkups, medicine reminders, chronic disease review, and caregiver-supported care.

Respiratory & Fever Screening

SpO₂, temperature, cough history, lung sound recording, and referral support.

Referral & Emergency Escalation

CHW → GP / Medical Officer → Specialist → Facility Referral.

Device-Agnostic Diagnostic Model

The Healodex Kit is a reference implementation, not a mandatory hardware lock-in.

Healodex Kit is a reference implementation using ESP32-based IoT and edge processing. BNHS can also support approved off-the-shelf medical devices, existing Community Clinic equipment, BLE/Wi-Fi devices, manual entry, and future government-approved diagnostic hardware.

BNHS supports:

  • ESP32-based prototype support
  • BLE / Wi-Fi
  • MQTT over TLS
  • Local buffering
  • Offline sync
  • Wired temperature probe
  • ECG lead support
  • Digital stethoscope audio capture
  • Pulse oximeter
  • BP input / manual integration
  • Device-agnostic architecture
  • Existing Community Clinic equipment
  • Approved off-the-shelf medical devices
  • Future government-approved diagnostic hardware
  • Manual entry when digital devices are unavailable

This reduces procurement friction and allows pilots to use available equipment while validating the service model.

The Healodex Kit

An R&D / reference implementation: a portable diagnostic and connectivity kit designed for Community Health Workers and local health service points. BNHS does not depend on proprietary hardware — the Kit is one option among approved and existing devices.
