Regret after decision to have a tubal sterilization.

To determine characteristics associated with regretting sterilization that can be determined preoperatively, we analyzed data from the Collaborative Review of Sterilization (CREST), a multicenter, prospective, observational study. Of 5022 women, 2.0% regretted having had a tubal sterilization at 1 year after the procedure and 2.7% did so after 2 years. Using a multivariate analysis to identify risk factors for regret, we found that almost all characteristics were more closely associated with regret at 1 year than at 2 years postoperatively. Of the characteristics we examined that could be objectively determined preoperatively, we considered only age less than 30 years and (for whites) a concurrent cesarean section to be risk factors for regret at 2 years after sterilization. However, in absolute terms, less than 10% of women with both those risk factors regretted having the procedure.
