Summary
The incidence of eclampsia increased significantly from 1973-99, contrary to international trends. Despite surveillance, cases were not prevented, highlighting the need for better prognostic tests for eclampsia.
Area of Science:
- Obstetrics and Gynecology
- Maternal-Fetal Medicine
- Public Health
Background:
- Eclampsia incidence and care patterns were analyzed over 27 years.
- Data spanned from 1973 to 1999 at a tertiary care hospital.
Purpose of the Study:
- To investigate changes in eclampsia incidence.
- To examine shifts in patient characteristics, comorbidity, and care.
- To compare outcomes across different time periods.
Main Methods:
- Swedish National Birth Registry used for case identification (39 cases).
- Incidences and outcomes compared across 1973-79, 1980-89, and 1990-99.
- Trend analysis applied to assess changes over time.
Main Results:
- Eclampsia incidence rose significantly: 3.0, 6.2, and 10.9 per 10,000 births (p=0.006).
- Patient characteristics and comorbidity remained consistent.
- Most cases (85%) had onset during hospitalization.
Conclusions:
- The rising incidence contrasts with international trends and previous national data.
- Hospital surveillance did not prevent all eclampsia cases.
- Improved prognostic tests are crucial for reducing eclampsia incidence.
