Area of Science:

  • Obstetrics and Gynecology
  • Maternal Medicine
  • Clinical Quality Improvement

Background:

  • Eclampsia remains a significant cause of maternal morbidity and mortality.
  • Early identification and management of deteriorating pregnant patients are crucial for improving outcomes.
  • The Maternal Early Warning Trigger (MEWT) tool was developed to aid in the early detection of clinical deterioration in obstetric patients.

Purpose of the Study:

  • To evaluate the impact of implementing the MEWT tool on the incidence of eclampsia.
  • To assess the effect of the MEWT tool on maternal and perinatal outcomes in women with hypertensive disorders.

Main Methods:

  • A retrospective observational study comparing two five-year epochs before and after MEWT tool implementation.
  • Analysis of data from a tertiary referral center with approximately 10,000 annual births.
  • Inclusion of all pregnant women registered and delivered at the study institute.

Main Results:

  • Eclampsia incidence decreased by 45.4% (from 1.1 to 0.6 per 1000 women, p=0.001), with a notable reduction in antepartum eclampsia.
  • Significant improvements were observed in maternal and perinatal outcomes for women with hypertensive disorders post-MEWT implementation.
  • The study included 37,043 women in the pre-MEWT period and 45,637 in the post-MEWT period.

Conclusions:

  • Integration of the MEWT tool into obstetric practice is effective in reducing eclampsia rates.
  • The MEWT tool contributes to improved maternal and fetal outcomes, particularly in managing hypertensive disorders.
  • The findings support the widespread adoption of early warning systems in obstetric care.
