Prescriber Demographics—The frequency of not prescribing isotretinoin did not vary by practice setting (χ 24=6.44, P=.1689) but did vary by age of the dermatologist (χ23=15.57, P=.0014). Dermatologists younger than 46 years were more likely (Figure) to report not prescribing isotretinoin because of the administrative burden of iPLEDGE. We speculate that this is because younger dermatologists are less established in their practices and therefore may have less support to complete registration without interruption of clinic workflow.
Dermatologists’ isotretinoin prescribing patterns due to iPLEDGE burden by dermatologist age. The results from the question, “Have you ever not prescribed isotretinoin to patients because the iPLEDGE system is too burdensome?” are shown in this mosaic plot. This mosaic plot shows the frequency of always prescribing (blue) or at times not prescribing (red) isotretinoin because of the burden of iPLEDGE by dermatologist age.
Comment
The results of our survey suggest that the administrative burden of iPLEDGE may be compelling prescribers to refrain from prescribing isotretinoin therapy to appropriate candidates when it would otherwise be the drug of choice.
Recent Changes to iPLEDGE—The FDA recently approved a modification to the iPLEDGE Risk Evaluation and Mitigation Strategy (REMS) program based on the advocacy efforts from the American Academy of Dermatology. Starting December 13, 2021, the 3 patient risk categories were consolidated into 2 gender-neutral categories: patients who can get pregnant and patients who cannot get pregnant.8 The iPLEDGE website was transitioned to a new system, and all iPLEDGE REMS users had to update their iPLEDGE accounts. After the implementation of the modified program, user access issues arose, leading to delayed treatment when patients, providers, and pharmacists were all locked out of the online system; users also experienced long hold times with the call center.8 This change highlights the ongoing critical need for a streamlined program that increases patient access to isotretinoin while maintaining safety.
Study Limitations—The main limitation of this study was the inability to calculate a true response rate to our survey. We distributed the survey via social media to maintain anonymity of the respondents. We could not track how many saw the link to compare with the number of respondents. Therefore, the only way we could calculate a response rate was with the total number of members in the group, which fluctuated around 4000 at the time we administered the survey. We calculated that we would need at least 351 responses to have a 5% margin of error at 95% confidence for our results to be generalizable and significant. We ultimately received 510 responses, which gave us a 4.05% margin of error at 95% confidence and an estimated 12.7% response rate. Since some members of the group are not active and did not see the survey link, our true response rate was likely higher. Therefore, we concluded that the survey was successful, and our significant responses were representative of US dermatologists.
Suggestions to Improve iPLEDGE Process—Our survey study should facilitate further discussions on the importance of simplifying iPLEDGE. One suggestion for improving iPLEDGE is to remove the initial registration month so care is not delayed. Currently, a patient who can get pregnant must be on 2 forms of contraception for 30 days after they register as a patient before they are eligible to fill their prescription.4 This process is unnecessarily long and arduous and could be eliminated as long as the patient has already been on an effective form of contraception and has a negative pregnancy test on the day of registration. The need to repeat contraception comprehension questions monthly is redundant and also could be removed. Another suggestion is to remove the category of patients who cannot become pregnant from the system entirely. Isotretinoin does not appear to be associated with adverse psychiatric effects as shown through the systematic review and meta-analysis of numerous studies.9 If anything, the treatment of acne with isotretinoin appears to mitigate depressive symptoms. The iPLEDGE program does not manage this largely debunked idea. Because the program’s sole goal is to manage the risk of isotretinoin’s teratogenicity, the category of those who cannot become pregnant should not be included.
Conclusion
This survey highlights the burdens of iPLEDGE for dermatologists and the need for a more streamlined risk management program. The burden was felt equally among all practice types but especially by younger dermatologists (<46 years). This time-consuming program is deterring some dermatologists from prescribing isotretinoin and ultimately limiting patient access to an effective medication.
