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)
Background
Pulmonary 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.
Methods
A 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).
Results
Sixty-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).
Conclusions
In 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.
期刊介绍:
The International Journal of Obstetric Anesthesia is the only journal publishing original articles devoted exclusively to obstetric anesthesia and bringing together all three of its principal components; anesthesia care for operative delivery and the perioperative period, pain relief in labour and care of the critically ill obstetric patient.
• Original research (both clinical and laboratory), short reports and case reports will be considered.
• The journal also publishes invited review articles and debates on topical and controversial subjects in the area of obstetric anesthesia.
• Articles on related topics such as perinatal physiology and pharmacology and all subjects of importance to obstetric anaesthetists/anesthesiologists are also welcome.
The journal is peer-reviewed by international experts. Scholarship is stressed to include the focus on discovery, application of knowledge across fields, and informing the medical community. Through the peer-review process, we hope to attest to the quality of scholarships and guide the Journal to extend and transform knowledge in this important and expanding area.
