New Evidence for Blood Clots With the Pill. Will Canadian Ob/Gyn Group Revise its Guidelines on Drospirenone?

April 26, 2011

The Society of Obstetricians and Gynaecologists of Canada (SOGC) has a chance to redeem itself and make good on its controversial new contraceptive guidelines.

As I wrote in my last post, the guidelines are tainted with undisclosed conflicts of interest, calling their recommendations into question.

This is a major change from the task force, which is a leader in mammography screening guidelines. It goes against the recommendation of many other major U.S. groups, including the American Cancer Society, which is strongly critical of the USPSTF move.

So, why the disagreement?

It’s a debate over the harms versus the benefits of screening.Read More »
