The danger doesn't wait for the next clinic visit.
SMS-based screening for pregnancy and postpartum complications.
Built for clinicians who can't be everywhere at once.
The Problem
78%
Postpartum hemorrhages go undiagnosed
50%
Maternal sepsis cases occur after a woman has already been sent home.
1.3 Million
In a study of 1.3 million pregnancies, twice as many women showed symptoms of pre-eclampsia as were ever diagnosed
The symptoms were there. They just weren't caught in time.
Late detection. Preventable deaths. Overburdened health systems.
The Solution
Proactive, automated screening that identifies high-risk patients before complications become emergencies.
Giving clinicians the early warning system they've never had.
Automated WhatsApp screening runs in the background, flagging high-risk patients and delivering alerts directly to the clinical team — before complications escalate.
No additional infrastructure. Works on any phone, in any clinic.
Estrid
Automated patient screening via WhatsApp.
Risk stratification with immediate clinical alerts.
Zero infrastructure required.
Automated patient screening via WhatsApp.
Zero infrastructure required.
High-risk patients are flagged automatically. Clinicians are notified immediately.
The Evidence of SMS
SMS-based health interventions have demonstrated:
✓ 98% message open rates (vs. 20% for apps)
✓ Improved medication adherence across multiple conditions
✓ Better health outcomes in maternal, HIV, and TB care
✓ High patient satisfaction and engagement
✓ 10-50x cost reduction vs. facility-based monitoring
WHO recommends mobile messaging as part of antenatal care (WHO Digital Health Guidelines, 2019)
Estrid applies this proven approach specifically to maternal health screening in resource-constrained settings, using WHO-validated clinical protocols.
Our Approach
Weekly Automated Screening
1
Pregnant and postpartum women receive screening questions via Whatsapp each week, tailored for both the pregnancy stage and postpartum period.
Intelligent Risk Assessment
2
Responses analyzed using WHO-validated protocols. High-risk & medium-risk answers trigger immediate alerts to healthcare workers.
Clinician Dashboard
3
Patient risk level (High/Medium/Low)
Specific symptoms flagged
Recommended next action
Escalation Protocols
4
High Risk: Immediate facility referral (within 24 hours)
Medium Risk: 48-hour clinician follow-up
Low Risk: Patient education and self-care guidance
5
Outcome Tracking
Every patient interaction automatically logged. Complete audit trail for medical records, donor reporting, and ministry compliance.
Aggregate data gives implementing partners real-time visibility into population-level maternal health trends — without additional administrative burden on clinical staff.
