Ectopic pregnancy rates in a non-Medicaid population are lower than previously reported

摘要

TO THE EDITORS: Since the publication of our article, we have learned that the paper by Trabert et al, which we cited extensively, had been subject to an error and published correction. In our article, we included the original (uncor-rected) results from that article in contextualizing our findings. Trabert et al reported rates of ectopic pregnancy among women in Group Health Cooperative, an insured population in Washington and Idaho with few (estimated 5%) Medicaid beneficiaries. In their original article, they reported ectopic pregnancy rates that ranged from 1.78% of all pregnancies from 1993-1995 to 2.45% from 2005-2007. They later corrected these rates to 1.71% (1993-1995) and 1.36% (2005-2007). In the time period corresponding to our study (2000-2003), Trabert et al originallyleported rates of 1.94% (1999-2001) and 2.00% (2002-2004) in Group Health Cooperative. They later corrected these to 1.47% and 1.39%, respectively.
