Field Nurse Offline Diagnostic Decision Tool
An interactive clinical decision support specification designed for ruggedized tablets, standardizing symptom screening, triage protocols, and digital referral generation for nurses at municipal health centers in Timor-Leste.
1. Frontline Clinical Mandate & Offline Design Rationale
Standardizing Primary Care Diagnostics in Rural Municipalities
Frontline nurses and midwives operating in municipal Centros de Saúde Comunitários (CSCs) across Timor-Leste frequently manage complex diagnostic decisions under challenging rural conditions without reliable real-time internet access.
The Field Nurse Offline Diagnostic Decision Tool provides a standardized, algorithm-driven clinical interface deployed on ruggedized tablets. Developed in alignment with guidelines from the Ministério da Saúde (MdS), the application guides clinicians through symptom triage, essential data logging, automated syndromic classification, and instant digital referral generation to regional hospitals and **Hospital Nacional Guido Valadares (HNGV)**—all while operating entirely offline.
2. Core Clinical Modules & Triage Decision Trees
Click on each clinical domain below to expand diagnostic screening pathways.
Module 1: Acute Respiratory Infections & Syndromic Screening
Screening Scope: Evaluates cough, fever, shortness of breath, and oxygen saturation parameters.
- Triage Prompting: Step-by-step checks for respiratory rate per minute, chest indrawing, and cyanosis in pediatric and adult patients.
- Tuberculosis (TB) Risk Flagging: Automatic screening prompts for chronic cough exceeding two weeks, unexplained weight loss, and night sweats, linking directly to GeneXpert testing workflows.
- Severity Scoring: Instantly categorizes cases into Routine Outpatient Care, Urgent Municipal Referral, or Emergency Hospital Transfer.
Module 2: Maternal Health, Antenatal Care & High-Risk Obstetric Triage
Screening Scope: Standardizes antenatal visit recording, gestational age tracking, and obstetric danger sign identification.
- Danger Sign Checklists: Rapid screening for severe headaches, blurred vision, vaginal bleeding, and reduced fetal movement.
- Automated Risk Stratification: Flags gestational diabetes, severe anemia, and pre-eclampsia risks for prioritized obstetric referral to regional maternity wards.
- Continuity of Care: Links primary antenatal logs with municipal midwife schedules and postpartum vaccination trackers.
Module 3: Endemic Fever Screening & Vector-Borne Disease Protocols
Screening Scope: Standardizes evaluation for acute febrile illness, suspected Dengue, and malaria risk factors.
- Rapid Diagnostic Test (RDT) Logging: Structured data entry fields for recording malaria and Dengue NS1/IgG/IgM test results.
- Warning Sign Prompts: Prompts nurses to assess persistent vomiting, abdominal pain, and mucosal bleeding requiring intravenous fluid resuscitation or hospital transfer.
- Outbreak Notification Trigger: Automatically flags localized fever spikes for inclusion in municipal and central epidemiological surveillance queues.
Module 4: Non-Communicable Diseases (NCDs) & Chronic Care Follow-Up
Screening Scope: Manages routine monitoring for hypertension, type 2 diabetes, and cardiovascular risk factors.
- Vital Sign Trending: Tracks blood pressure, blood glucose, and body mass index over sequential patient visits.
- Treatment Adherence Prompts: Clinical reminders for medication refills, lifestyle counseling, and complication screening.
| Clinical Domain | Primary Target Users | Offline Decision Support Output | Referral Action Trigger |
|---|---|---|---|
| Respiratory & TB | CSC General Nurses & Triage Officers | Syndromic severity score & TB screening checklist | GeneXpert lab order or HNGV emergency transfer |
| Maternal & Antenatal | Municipal Midwives & Maternal Health Nurses | Obstetric risk level & danger sign alerts | High-risk referral to regional hospital maternity unit |
| Endemic Fevers | Frontline Clinic Nurses & Community Workers | RDT result logging & dengue warning sign prompts | Fluid management protocol or hospital admission |
| Chronic NCD Care | Chronic Disease Clinic Nurses | Blood pressure/glucose trending & medication reminders | Physician consultation scheduling |
3. User Interface Design & Frontline Usability Principles
Bilingual Prompting Interface
Designed with intuitive dual-language support (Tetum and Portuguese) to match the official administrative and clinical communication standards of Timor-لeste's health workforce.
Low-Literacy Visual Icons
Employs high-contrast graphical symptom icons and color-coded triage bands (Green, Yellow, Red) to accelerate patient assessment speed and reduce data entry fatigue.
Zero-Click Offline Synchronization
Clinicians never have to manually execute a "sync" button; patient records entered offline automatically queue and upload via the background store-and-forward engine when signal returns.
Built-In Clinical Reference Library
Includes a fully searchable offline library of national clinical guidelines, drug dosage calculators, and emergency management protocols directly on the tablet.
