These findings suggest that residents should be better trained to recognize the diagnostic criteria for the different degrees of eclampsia and preeclampsia, and that doctors should be more specific when they chart the diagnoses, since this influences patient management, she said at the annual meeting of the Central Association of Obstetricians and Gynecologists.
The study grew out of a larger evaluation of the causes of maternal morbidity conducted by Dr. Geller and her associates.
They began examining cases coded as 642.5 (severe preeclampsia) or 642.6 (eclampsia), "but when we started reviewing the charts, we found that they didn't necessarily correspond" to the codes they were assigned, said Dr. Geller, director of the University of Illinois Center of Excellence in Women's Health, Chicago.
The researchers then reexamined cases for the diagnostic criteria of eclampsia or preeclampsia as defined by the American College of Obstetricians and Gynecologists. The criteria were then compared with the ICD-9 codes assigned to each case.
The researchers studied 135 cases from the discharge database maintained at the University of Illinois Hospital between 1999 and 2001, including all of those coded as eclampsia or severe preeclampsia, plus 33% of all cases coded as mild preeclampsia ...
