openMFM is the public teaching layer for Maternal-Fetal Medicine: evidence-based slide decks, patient education, and clinical tools that stay usable in real care.

The home page pulls its newest previews directly from the top of the shared presentation feed, so the latest deck shows up here first.
Provider education deck on the optimal timing for diagnosis and management planning in placenta accreta spectrum, including first-trimester risk recognition, targeted second-trimester ultrasound, late pregnancy reassessment, multidisciplinary planning, delivery timing, and transvaginal ultrasound safety.
Stepwise sonographic education deck for diagnosing chorionicity in twin pregnancies, including optimal timing, lambda and T signs, membrane and placental assessment, discordant fetal sex, documentation, and when to default to monochorionic management or refer to MFM.
Clinical overview of marginal cord insertion in pregnancy, including definition, prevalence, associated growth and perinatal risks, antenatal surveillance, delivery planning, and how marginal insertion differs from velamentous cord insertion.
Evidence-based clinical education deck on delivery timing for gestational diabetes, including A1GDM, A2GDM, poor glycemic control, refractory disease, suspected macrosomia, neonatal risk tradeoffs, and ACOG/SMFM/NICE-aligned timing windows.
Core resources that clinicians and patients return to most often across diabetes, fetal growth, and hypertensive disease.
Comprehensive patient education on gestational diabetes: mechanism, screening (GCT/GTT), A1 vs A2 classification, blood sugar targets, medical nutrition therapy, exercise, insulin vs metformin, fetal surveillance, delivery timing, breastfeeding benefits, and long-term diabetes prevention. Based on ACOG PB #190, SMFM, and ADA 2025.
Comprehensive patient guide to fetal growth restriction: initial workup including amniocentesis, TORCH infection panel, autoimmune testing, Doppler surveillance, and delivery timing per ACOG and SMFM guidelines.
Evidence-based clinical update on preeclampsia: two-stage pathophysiology, ACOG 2019 diagnostic criteria (proteinuria not required), severe features, FMF first-trimester screening, aspirin prophylaxis (ASPRE trial), antenatal surveillance, acute BP management, magnesium sulfate dosing, delivery timing, HELLP syndrome, postpartum management, and long-term cardiovascular risk counseling.
Evidence-based calculators and decision-support microsites
Interactive patient decision guide for cell-free DNA prenatal screening (NIPT). Covers whether to pursue NIPT based on age, risk factors, and patient values — and explains what a positive result means, including condition-specific and age-stratified positive predictive values (PPV), per ACOG/SMFM guidelines.
Interactive prenatal risk stratification and counseling tool for Vein of Galen Malformation (VOGM). Evaluates fetal MRI brain parenchymal findings, cardiac hemodynamics, malformation morphology, and systemic findings to generate a tiered risk assessment (Critical / High / Standard) with evidence-based clinical recommendations and counseling guidance.
A dual-audience periviability counseling resource covering survival and morbidity outcomes by gestational age (22–25 weeks), prognostic factors, family decision-support questions, key clinical terminology, and ACOG/SMFM guideline references — for patients, families, and clinicians.
Interactive cervical length screening tool and patient education resource covering measurement thresholds, risk stratification, progesterone therapy, cerclage indications, pessary considerations, and ACOG/SMFM guideline-based preterm prevention strategies.
Evidence-based risk calculator for aspirin prophylaxis.
Dual-audience resource for parents and clinicians.
Gestational diabetes screening timing per ACOG 2024.
Hypertension classification tool per ACOG PB #222.
INTERGROWTH-21st, Hadlock, and WHO standards.
FGR surveillance and delivery timing per SMFM #52.
Risk assessment for patients with prior preterm birth. Covers recurrence risk, contributing factors, and prevention strategies.
Comprehensive patient and provider education on Hydrops Fetalis. Covers immune and non-immune causes, diagnostic workup, prognosis, and delivery planning.
Interactive patient education on fetal kick counting and movement monitoring. Covers Cardiff Count-to-Ten method, decreased fetal movement, and when to contact your provider. Includes a dedicated mobile-optimized version.
