Abstract Background Pregnancy related cardiomyopathy is a significant cause of maternal morbidity and mortality globally. A presumed overlap between normal pregnancy-associated symptoms and clinical symptoms of cardiomyopathy contributes to delays in diagnosis and increased risk of maternal mortality. Purpose We sought to evaluate the association between patient-reported cardiovascular symptoms and the presence of cardiomyopathy among pregnant and postpartum patients. We hypothesize that individual cardiovascular symptoms are unrelated to the presence of cardiomyopathy. We also evaluated the use of a novel adaptation of a validated health status questionnaire in relation to cardiomyopathy. Methods We enrolled 48 pregnant (>13 weeks) and postpartum (up to 12 months) participants in a prospective study between October 2021 and February 2022. All study participants completed a baseline questionnaire, which included current cardiovascular symptoms, an assessment of health status using an adapted version of the Kansas City Cardiomyopathy Questionnaire (KCCQ-12), followed by a resting transthoracic echocardiogram on the same day. We defined cardiomyopathy as a left ventricular ejection fraction (LVEF) <50% based on 2-D echocardiography. Fisher's exact and Wilcoxon rank-sum tests were employed to evaluate the association between reported cardiovascular symptoms, the adapted KCCQ-12 (KCC-A) score, and cardiomyopathy. Results At the time of enrollment, 67% were pregnant and 33% postpartum. Forty-eight percent identified as White, 31% as Black, 10% as Asian, and 10% as other race. The median age was 31 years (Q1: 28, Q3: 35) and 6% had an LVEF <50%. We found no statistically significant association between four reported cardiovascular symptoms (shortness of breath, orthopnea, fast breathing, and episodes of “asthma” that did not improve with inhalers or other treatment) and cardiomyopathy or medial E/e' ratio. KCC-A scores were low in the study population overall (median 52; Q1:40, Q3: 61). We demonstrated a significantly lower KCC-A score among women with LVEF <50% (median 24; Q1: 15, Q3: 44) compared to women with LVEF ≥50% (median 54; Q1: 44, Q3: 61) p=0.02. Conclusions We showed no significant association between individual cardiovascular symptoms and cardiomyopathy in an obstetric population. However, we demonstrate for the first time that an adapted KCCQ-12 questionnaire for health status assessment could potentially identify women with a high-likelihood of cardiomyopathy during the peripartum period who may benefit from additional evaluation including echocardiography. Larger studies are needed to validate this finding. Funding Acknowledgement Type of funding sources: Foundation.

IntroductionWe calculate the financial margins for delivery of routine antenatal care as reimbursed by Medicaid. Prenatal care cost varies with overhead, health care provider type, and number of office visits. Antenatal care is only one component of the global maternity bundle, which also includes intrapartum and postpartum care.MethodsTime for provision of low‐risk antenatal care was determined prospectively from a study of 133 low‐risk pregnant patients. Health care provider time cost was estimated using mean wages for obstetricians and midwives. Margins were estimated by subtracting cost of provider services and overhead for the antenatal component of maternity care from total Medicaid reimbursement for the pregnancy global package (CPT 59400) using 2015 dollars. The maternity bundle elements of routine prenatal laboratory tests, ultrasounds, intrapartum care, and postpartum care were not included in our analysis of cost components.ResultsPatients received an average of 215 minutes of direct provider time per pregnancy. At the 50th percentile for physician payment and assuming overhead is 53.4% of revenue, practice margins varied by state from −$1067 to +$675, with a median of −$357. Median margins for midwifery care were +$15, with a range of −$579 to +$885. Margins were negative if overhead costs exceeded 33% of revenue for physician care and 55% of revenue for midwifery care.DiscussionIn many states, Medicaid reimbursement for the global maternity package is less than the actual cost of antenatal care alone. Improving reimbursement or decreasing costs is necessary to make maternity care more cost‐effective.

INTRODUCTION: This study calculates the financial margins for delivery of routine antenatal care as reimbursed by Medicaid. Prenatal care cost varies with overhead, provider type, and number of office visits. Antenatal care is only one component of the global obstetric bundle, which also includes intrapartum and postpartum care. METHODS: Revenue was based on 2015 Medicaid reimbursement for the pregnancy global package (CPT 59400). All fifty states were represented. Provider time cost was estimated using mean wages for obstetricians and midwives, or using national mean wage data when state-specific data was unavailable. Staff time for provision of low risk prenatal care was determined prospectively from a study of 133 low risk patients. Sensitivity analysis was performed by varying overhead as a percentage of total revenue. Routine prenatal labs, ultrasounds, intrapartum care, and postpartum care were not included in our analysis. RESULTS: Patients received an average of 215 minutes of direct provider time per pregnancy. At the 50th percentile for physician payment and assuming overhead is 40% of revenue, practice margins varied by state from -$1,061 to +$785, with a median of -$161. This does not include the cost of intrapartum or postpartum care. The median margin for antenatal care was negative if overhead exceeded 18% of revenue. CONCLUSION: In a majority of states, reimbursement for the global obstetric package reimbursed by Medicaid is less than the actual cost of prenatal care alone. Improving reimbursement or decreasing costs is necessary to make maternity care cost-effective for obstetrics practices.
