Guidance

In the case of multiple births, map the first delivery date/time (Baby A) as the delivery date/time for the encounter.

This measure allows for 2 approaches to determine estimated gestational age (EGA) in the following order of precedence:

1. The EGA is calculated using the American College of Obstetricians and Gynecologists ReVITALize guidelines.*

2. The EGA is obtained from a discrete field in the electronic health record. This option is only used when the calculated EGA is not available.

Wherever gestational age is mentioned, relative to the delivery, the intent is to capture the last estimated gestational age prior to or at the time of delivery.

 

*ACOG ReVITALize Guidelines for Calculating Gestational Age:

 

Gestational Age = (280-(EDD minus Reference Date))/7

--Estimated Due Date (EDD): The best obstetrical Estimated Due Date is determined by last menstrual period if confirmed by early ultrasound or no ultrasound performed, or early ultrasound if no known last menstrual period or the ultrasound is not consistent with last menstrual period, or known date of fertilization (eg, assisted reproductive technology)

--Reference Date is the date on which you are trying to determine gestational age. For purposes of this eCQM, Reference Date would be the Date of Delivery.

Note however the calculation may yield a non-whole number and gestational age should be rounded off to the nearest completed week. For example, an infant born on the 5th day of the 36th week (35 weeks and 5/7 days) is at a gestational age of 35 weeks, not 36 weeks.

This eCQM is an episode-based measure. An episode is defined as each inpatient hospitalization or encounter that ends during the measurement period.

This version of the eCQM uses QDM version 5.6. Please refer to the QDM page for more information on the QDM.

Rationale *See CMS1028v1.html

The United States (US) experiences higher rates of maternal morbidity and mortality than most other developed countries. These rates have continued to trend upward in recent decades (CDC, n.d.). Research indicates that the overall rate of severe maternal morbidity (SMM) increased by almost 200% between 1993 and 2014 to 144 per 10,000 delivery hospitalizations (CDC, n.d.), with more than 25,000 women per year experiencing obstetric complications (U.S. Department of Health and Human Services, 2020). Recent maternal mortality data from 2018 reveal that 658 women in the US died from maternal causes, resulting in a rate of 17.4 deaths per 100,000 live births, with 77% of the deaths attributed to direct obstetric causes like hemorrhage, preeclampsia, obstetric embolism, and other complications (Hoyert & Minino, 2018). 144 per 10,000 women hospitalized for delivery have experienced SMM, including hemorrhage, embolism, hypertension, stroke, and other serious complications (CDC,2020). Racial and ethnic disparities for Black women and Hispanic women are at a significantly higher risk for developing these complications than are Non-Hispanic White women (Leonard et al., 2019). Increasing rates of SMM are resulting in increased healthcare costs, longer hospitalization stays and impacts on a woman's health.

There is limited national evaluation of hospitals' performance on maternal morbidity and mortality although SMM is widely used at the population level. SMM is linked to maternal mortality, varies significantly among hospitals, and has significant racial/ethnic and urban/rural disparities. SMM is a cost driver for both Medicaid and commercial plans. This measure is important as it will assist in the discovery and understanding of SMM patterns which can lead to improvements in the safety and quality of maternal care necessary to reduce SMM rates.

Stratification *See CMS1028v1.html

Stratum1: Delivery hospitalizations with severe obstetric complications excluding hospitalizations where transfusion was the only severe obstetric complication.

Additionally, this measure will be stratified by race and ethnicity after measure submission.

Clinical Recommendation Statement *See CMS1028v1.html

Healthy People 2030 Measure (MICH-05): Reduce severe maternal complications identified during delivery hospitalizations

The American College of Obstetricians and Gynecologists (the College) and the Society for Maternal-Fetal Medicine (SMFM) recommend identifying potential cases of severe maternal morbidity for further review, with a focus on outcomes and complications, and consider this an important step toward promoting safe obstetric care.
