maternal early warning tools, maternal morbidity, ICU admission
Introduction: Several tools for early warning are being used right now. The National Council for Patient Safety in the US recently suggested using maternal early warning tools (MEWTs), and the Modified Early Obstetric Warning System (MEOWS) has been suggested in Great Britain.
Objectives: To determine the diagnostic accuracy of maternal early warning tools (MEWTs) in predicting maternal morbidity in comparison with ICU admission as reference standard.
Materials & Methods: The research was done at the PIMS Hospital in Islamabad from December 23, 2017, to June 22, 2018, in the Department of Obstetrics and Gynecology. It used a descriptive, cross-sectional, and validative methodology. A total of 499 pregnant women between the ages of 18 and 40 who were more than 20 weeks along (on LMP) were included. We didn't include women who had valve heart disease, chronic high blood pressure, or coagulopathies. Then, the researcher herself looked at all the women using maternal early warning tools (MEWTs) to guess how likely they were to end up in the intensive care unit (ICU) after giving birth, and the final decision was made 24 hours later.
Results: In total, 84 (16.83%) patients were admitted to the intensive care unit (ICU), while 415 (83.17%) patients were not admitted to the ICU. Out of the MEWT-positive cases, 69 were real positives and 31 were false positives. There were 399 patients who did not have a MEWT. Of these, 384 were true negatives and 15 were fake negatives (p-value = 0.0001). That's 82.14% for sensitivity, 92.53% for specificity, 69.0% for positive predictive value, 96.24% for negative predictive value, and 90.78% for diagnostic accuracy of maternal early warning tools (MEWTs) in predicting maternal illness.
Conclusion: This study concluded that diagnostic accuracy of maternal early warning tools (MEWTs) in predicting maternal morbidity is quite high.
