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 deck for an inconclusive NIPT (no-call) result: what a no-call means, why it occurs (low fetal fraction, high BMI, early gestational age), the elevated but modest chromosomal risk (~3–10%), and a clinical decision framework covering repeat NIPT versus diagnostic testing (CVS or amniocentesis) with ultrasound correlation.
Clinician-facing review of no-call NIPT results for the Labcorp educational program: low fetal fraction, atypical and mosaic results, platform differences, sgNIPT false negatives, and the clinical and patient-level consequences of delayed or indeterminate cfDNA screening.
Featured clinician deck on Potter syndrome versus Potter sequence, including the pathophysiology of prolonged oligohydramnios, bilateral renal agenesis, classic sonographic findings, differential diagnosis, prognosis, delivery considerations, and counseling points for obstetric and MFM practice.
Structured first-visit evaluation framework for HbSS disease in pregnancy: hematology baselines (Hgb, reticulocyte count, LDH), transfusion safety workup (extended red cell phenotyping, alloantibody screen), renal and hepatic assessment, preeclampsia risk and aspirin prophylaxis, iron and vitamin D status, and infectious disease testing. Emphasizes preventing alloimmunization and establishing organ-function baselines before complications arise. Based on ACOG/SMFM guidance.
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.
