Our objective was to identify birth hospitalization severe maternal morbidity (SMM) diagnoses that were also coded during prior encounters and, thus, potentially falsely carried forward as de novo SMM events. This retrospective cohort study included pregnant patients with births between 2016 and 2020. We applied the algorithm occurring prepregnancy, antepartum, postpartum. The primary outcome rate of recorded on previous encounters. There 1,380 (1.8%) birthing SMM. Of codes at...

Objective: To evaluate the incidence of implementation universal cervical length (CL) screening for preterm birth (PTB) prevention among institutions with Maternal–Fetal Medicine (MFM) fellowship training in United states.Methods: In January 2015, we conducted a national survey MFM Fellowship Programs regarding CL screening, defined as women singleton gestations without prior spontaneous PTB. We identified whether transabdominal ultrasound (TAU) or transvaginal (TVU) was used screening....

Despite this risk, some women do proceed with beyond 25 weeks; however, information on these cases remains elusive limited case series reports small samples. Current recommendations surrounding delivery PHTN recommend cesarean (CD), but new...

( Obstet Gynecol. 2024;143(4):582–584. doi: 10.1097/AOG.0000000000005537) Administrative data play a crucial role in understanding severe maternal morbidity (SMM) events, yet their interpretation heavily relies on coding quality. Overestimation of SMM during birth hospitalizations might occur due to International Classification Diseases, Tenth Revision (ICD-10) codes being carried forward from predelivery events. This study aimed describe distribution across the antepartum, birth, and...
