Open-Source Tools for Maternal-Fetal Medicine
Two posters. One purpose: make MFM education and clinical tools open, accessible, and usable in practice.
Built by a physician.
Shared with everyone.
MFM education and counseling often depend on proprietary tools, materials confined to individual institutions, and internet information of uneven quality. OpenMFM brings teaching resources and browser-based tools into one publicly accessible platform.
These two posters describe that work at different scales: a focused cervical length counseling workflow and the broader education platform that supports it.
A Physician-Developed Open-Source Web Tool for Cervical Length Screening and Preterm Birth Prevention Counseling
Three inputs organize a counseling conversation: pregnancy type, prior spontaneous preterm birth, and transvaginal cervical length.
You answer
- Singleton or twin pregnancy?
- Prior spontaneous preterm birth before 34 weeks?
- Transvaginal cervical length in millimeters at 18–24 weeks?
The tool provides
- Counseling content on vaginal progesterone, cerclage, and surveillance
- A printable patient summary
- Plain-language explanations and warning signs
Clinical reference: SMFM Consult Series #70 (2024), management of short cervix in individuals without a history of spontaneous preterm birth. This article describes the project; individual care requires clinical assessment.
OpenMFM: An Open-Source Digital Platform for Maternal-Fetal Medicine Education and Clinical Decision Support
The public teaching layer for MFM: slide decks, patient education, and interactive tools that clinicians can access, inspect, and share.
Site snapshot: October 8, 2026. The submitted platform summary describes an earlier stage with 90 presentations across 30+ conditions and content domains. Homepage tool counts reflect the curated feed, not every microsite in the full library.

341 · Cervical length screening
Clinical need. Cervical-length recommendations can be difficult to translate into consistent point-of-care education and patient counseling.
Objective. Develop and describe a free browser-based resource that organizes current SMFM and ACOG recommendations for clinicians, trainees, and patients.
Study design. Descriptive implementation study of an open-source cervical-length module within OpenMFM.org.
Workflow. Five steps bring the pathway together: identify context, review measurement, stratify risk, compare options, and counsel together. The resource connects screening indications and risk history with ultrasound thresholds and timing, clinical context, progesterone, cerclage, surveillance, and individualized discussion.
Results. The module was deployed as a free, no-login resource within OpenMFM.org. It integrates screening rationale, risk stratification, ultrasound thresholds, management decision points, and counseling content in one visual format.
Initial experience. Qualitative feedback from clinical staff and patients was favorable, with users reporting value for counseling consistency and shared decision-making.
Limitations. Feasibility and perceived utility were described; patient or clinical outcomes were not measured. The study did not include a quantitative usability or outcome comparison.
Next evaluation. Counseling consistency, trainee knowledge, patient comprehension, and workflow use and reach.
Conclusion. Evidence-based recommendations can be translated into a scalable, open digital resource for preterm-birth prevention education and counseling.
Take-home message. Open-source decision support can make cervical-length counseling more structured, visible, and shareable.

Problem. MFM education and decision support often depend on proprietary products, siloed institutional materials, or unvetted internet content.
Objective. Describe a physician-developed, open-source platform delivering guideline-aligned education and interactive clinical decision support for patients, clinicians, trainees, and sonographers.
Study design. Descriptive implementation study of a free, MIT-licensed browser platform built with standard web technologies and no institutional login requirement.
Platform snapshot at abstract submission. 90 evidence-based presentations across 30+ MFM conditions and domains, with 13 interactive clinical tools.
What was deployed. Education across fetal growth, diabetes, hypertension, twins, genetics, anomalies, and infection; fetal biometry and FGR surveillance tools; preeclampsia, hypertension, and GDM screeners; periviability and cervical-length counseling resources; and public source code under an MIT license.
Implementation finding. One physician built an open MFM learning system that works in any modern browser. The platform connects evidence-based teaching, point-of-care tools, and patient counseling without software licensing or institutional infrastructure.
Limitations. Feasibility was demonstrated. Clinical effectiveness was not tested in this descriptive study.
Next evaluation. Usage and reach analytics, patient comprehension, workflow efficiency, and educational value.
Conclusion. A physician-developer can create a comprehensive, guideline-aligned, open-source MFM platform using accessible web technologies.
Take-home message. Open web tools can make evidence-based MFM education easier to reach, teach, and adapt.
