Primary Outcome Measures:
  • Number of women per month who had a diagnosis of pre-eclampsia at OSU Medical Center when they delivered a baby. [ Time Frame: Data assessed from patient charts retrospectively ] [ Designated as safety issue: No ]

Estimated Enrollment: 500
Study Start Date: January 2009
Study Completion Date: July 2009
Primary Completion Date: April 2009 (Final data collection date for primary outcome measure)
Detailed Description:

This study is a retrospective review of obstetrics charts of women who gave birth at OSU Medical Center between January 01, 2005 and December 31, 2007.

Included will be patient charts of women > 18 years old who were admitted to OSUMC for delivery (both cesarean and vaginal deliveries) between 1/1/05 and 12/31/07, with and without a diagnosis of pre-eclampsia. The data collected will be recorded in a spreadsheet by month/day of delivery, and whether pre-eclampsia was a diagnosis. Also included will be total number of deliveries per month and total number of pre-eclampsia diagnoses per month. The rate of pre-eclampsia will be calculated.

A contingency table with corresponding chi square test will be performed to determine whether there is a significant relationship of the diagnosis of pre-eclampsia with seasonality, defined primarily by month. Certain data occurring during transition periods between seasons may be excluded from analyses.
