Reach and effectiveness of a non-university cardio-obstetrics program

Current guidelines recommend multidisciplinary cardiovascular obstetric programs (CVOB) to manage complex pregnant patients with cardiovascular disease. Minimal evaluation of these programs exists, with most of these programs offered at university-based centers.

A cohort of 113 patients managed by a CVOB team at a non-university health system (2018-2019) were compared to 338 patients seen by cardiology prior to the program (2016-2017). CVOB patients were matched with comparison patients (controls) on modified World Health Organization (mWHO) category classification, yielding a cohort of 102 CVOB and 102 controls.

CVOB patients were more ethnically diverse and cardiovascular risk was higher compared to controls based on mWHO ≥ II-III (57% vs 17%) and. After matching, CVOB patients had more cardiology tests during pregnancy (median of 8 tests vs 5, p < .001) and were more likely to receive telemetry care (32% vs 19%, p = .025). The median number of perinatology visits was significantly higher in the CVOB group (8 vs 2, p < .001). Length of stay was a half day longer for vaginal delivery patients in the CVOB group (median 2.66 vs 2.13, p = .006).

Implementation of a CVOB program resulted in a more diverse patient population than previously referred to cardiology. The CVOB program participants also experienced a higher level of care in terms of increased cardiovascular testing, monitoring, care from specialists, and appropriate use of medications during pregnancy.
