High emergency care use during pregnancy associated with increased risk of Severe Maternal Morbidity ,finds study
Pregnant women who frequently seek emergency care during pregnancy may be at a higher risk of experiencing severe maternal morbidity and other negative outcomes. Recent cohort study explored the association between frequent unscheduled care visits during pregnancy Data Source and the risk of severe maternal morbidity (SMM) at the time of birth.
The study used data from the Massachusetts Pregnancy to Early Life Longitudinal (PELL) Data System, which links birth and fetal death records to corresponding maternal hospital encounters. The study population included 774,092 pregnant individuals in Massachusetts between October 1, 2002 and March 31, 2020. The key exposure was 4 or more emergency care visits, defined as either an emergency department (ED) visit or observational stay (OS) during pregnancy not resulting in hospital admission.
The main outcome was the odds ratio for SMM at the time of birth. Study Results - ContinuedThe results showed that 31.3% of the sample had at least 1 unscheduled visit during pregnancy, and 3.3% had 4 or more visits. High emergency care use was more common among younger individuals, those with Hispanic or non-Hispanic Black race/ethnicity, those with public insurance, and those with a comorbidity or opioid use in the year prior to pregnancy. Study Results - ContinuedIn the multivariable analysis, those with 4 or more unscheduled visits had an adjusted odds ratio of 1.46 (95% CI, 1.29-1.66) for SMM compared to those with 0 visits. Additionally, 43.8% of those with 4 or more unscheduled visits used multiple hospitals during pregnancy. The study concludes that high emergency care use during pregnancy is associated with an increased risk of SMM. Given the fragmentation in care for those with frequent unscheduled visits, the authors suggest that community-based and integrated solutions across health systems may be most beneficial for this high-risk population.
