A risk management program aimed at preventing fetal exposure to isotretinoin: retrospective cohort study.
BACKGROUND
Preventing fetal exposure to isotretinoin is an important public health goal. Since approval of isotretinoin (1982), the Food and Drug Administration has implemented several unsuccessful risk management programs aimed at preventing fetal exposure. The Kaiser Permanente isotretinoin risk management program included electronic capture of all isotretinoin prescriptions and the documentation of pregnancy testing with each dispense.


OBJECTIVE
Our aim was to analyze the success of Kaiser Permanente's program at improving pregnancy testing rates and reducing fetal exposure.


METHODS
This was a retrospective cohort study.


RESULTS
Pregnancy testing rates improved after implementation of the Kaiser Permanente program. However, the rate of fetal exposure to isotretinoin did not change (0.21% before vs 0.23% after, P = .85). LIMITATIONS/CONCLUSION: In this study, linking a negative pregnancy test to isotretinoin dispensing did not reduce fetal exposures. Patient failure to use two contraceptive methods was the most common reason for fetal exposure. These results have important implications for iPLEDGE, the new isotretinoin risk management program mandated by the Food and Drug Administration.
