The Obstetric Comorbidity Index (OB-CMI) and its association with ICU admission and length of hospital stay in pregnant patients with pulmonary hypertension: a retrospective cohort study (1996-2025).
Article in International journal of obstetric anesthesia, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundPulmonary hypertension in pregnancy is associated with adverse pregnancy outcomes, such as prolonged hospitalization, intensive care unit (ICU) admission, and high maternal mortality. The Obstetric Comorbidity Index (OB-CMI) assesses maternal risk for these outcomes; however, its predictive power in patients with pulmonary hypertension remains unknown. This study evaluates maternal and neonatal outcomes in patients with pulmonary hypertension and examines whether a higher comorbidity burden is associated with longer hospitalization and ICU admission.
methodsA retrospective cohort study was conducted using electronic health records from Mass General Brigham and Tufts Medical Center (1996-July 2025). Patients with pulmonary hypertension and pregnancies beyond 20 weeks' gestation were identified using the International Classification of Disease-9/10 codes. Data were collected via manual chart review, and descriptive statistics and univariate regression analyses were performed (P < 0.05).
resultsSixty-five pregnancies among 61 patients were identified. The median maternal age was 32.9 (interquartile range 28.9-36.6) years. The maternal mortality rate was 3 %, with both deaths occurring before 2000. Most patients (56.9 %) had cesarean delivery under epidural anesthesia (69.2 %). Median OB-CMI was 9, and median hospitalization was 6 days. Pulmonary artery pressure was associated with prolonged hospitalization (P = 0.004) and ICU admission (P = 0.027). OB-CMI showed borderline association with ICU admission (P = 0.046), but not hospitalization duration (P = 0.580).
conclusionsIn patients with pulmonary hypertension, ICU admission and prolonged hospitalization were common and associated with pulmonary arterial pressure but not OB-CMI. Further studies are needed to develop scoring tools specific to pulmonary hypertension patients to improve risk assessment.
