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.
Patient counseling on Trisomy 13 (Patau syndrome): what the diagnosis means, how NIPT works and its PPV limitations, why false positives occur (confined placental mosaicism, vanishing twin), characteristic sonographic findings, diagnostic confirmation via amniocentesis or CVS, prognosis, and a shared decision-making pathway. Based on ACOG/SMFM guidance.
Evidence-based clinical guide to opioid use disorder (OUD) and neonatal opioid withdrawal syndrome (NOWS) in pregnancy: placental transfer of oxycodone, NOWS symptoms and duration, obstetric complications, contraindication of abrupt cessation, analgesic hierarchy, prescribing principles, and postpartum surveillance. Based on ACOG, SMFM, and SAMHSA guidelines.
Patient education on induction of labor at 38 weeks when ultrasound suggests a large-for-gestational-age fetus, including what the estimate means, risks of ongoing growth, 2026 randomized-trial meta-analysis data, safety tradeoffs, and shared decision-making points.
Patient education on early fetal heart rate at 6 weeks, including expected ranges, how borderline or slow measurements are interpreted, why repeat ultrasound matters, and when to seek care.
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.
