Compliance with the pregnancy prevention program among women initiating isotretinoin treatment between 2014 and 2021: A nationwide cohort study on the French Health Data System (SNDS)

BACKGROUND

Despite the French pregnancy prevention program (PPP), a considerable number of pregnancies are potentially exposed to oral isotretinoin. New measures were taken by the French Medicines Agency, including the restriction of initial isotretinoin prescriptions to dermatology specialists in May 2015 and a new information campaign on teratogenicity in January 2019.

OBJECTIVES

The aims were to: describe, between 2014 and 2021, compliance with PPP recommendations: isotretinoin use as a second-line treatment, first prescription by a dermatology specialist, monthly prescription renewal and pregnancy testing (PT); assess the effect of the 2015 and 2019 measures on PT compliance; and identify the determinants of PT noncompliance.

METHODS

A retrospective cohort study was conducted among women aged 11-50 years initiating isotretinoin between 2014 and 2021 using the French Health Data System. PT compliance corresponded to pregnancy test completion and specific delays between prescription and dispensation. Time series analyses were performed to evaluate the effect of the 2015 and 2019 measures on PT compliance, and log-binomial and Poisson multivariate regression models were used to identify the determinants of PT noncompliance.

RESULTS

Isotretinoin was prescribed as a second-line treatment in 64% of initiations, mainly by dermatology specialists (92%). A new monthly prescription was observed in 98% of dispensations. PT compliance reached 61%, 72% and 25% at initiation, renewals and end of treatment, respectively. The 2015 measure was associated with better PT compliance at initiation and renewals. The 2019 measure had no significant effect on PT compliance at the initiation or end of treatment but was associated with a decrease in PT compliance at renewals. Age, low socioeconomic level, initiation by a nondermatology specialist and during summer were associated with PT noncompliance.

CONCLUSIONS

Understanding factors associated with PT noncompliance could help to target specific subpopulations of women treated with isotretinoin.

[Evaluation and impact of "pregnancy" pharmaceutical pictograms among 281 women]

In France, since 2017 new pharmaceutical pictograms appeared on drugs with a potentieal risk during pregnancy. This apposition, left to the discretion of marketing authorization holders, has uncertain consequences for women's reactions to them. The present survey is the first one interested in the opinion of the women concerned (pregnant or of childbearing age) as well as on the interpretation that they make of it. The survey answers enhanced that the pregnancy pictogram is an initiative welcomed by women who estimate that it secures drug intake. However, we demonstrate a poor understanding of the message conveyed by these pictograms (more than 50 % think they concern breastfeeding and more than 10 % fertility) and inappropriate behavior towards them (more than 80  of women pregnant stopped or decreased their medication immediately, without medical advice). The survey also highlights the need for information of women concerned by these pictograms and the limited information given by health professionals on this subject. It seems urgent to revise the law, to limite the use of these pictograms that appear to be too broad, incoherent and sometimes unjustified. In addition, public information seems an essential issue when focusing on these new pharmaceutical pictograms.

Antidepressant use in pregnancy: knowledge transfer and translation of research findings

RATIONALE

Knowledge transfer and translation (KT) has become an important component in health care systems worldwide. Antidepressant use in pregnancy has become a controversial subject for a number of reasons, including differing interpretations of study results.

METHODS

Selected key articles were indentified and retrieved from the literature. Relevant information was extracted and synthesized into themes, addressing each of the stated objectives.

OBJECTIVES

(1) To determine how knowledge regarding the safety/risk of antidepressant use in pregnancy is created; (2) to describe different research models and statistical analyses that have been used, so as to critically evaluate the results; and (3) to identify how this information is currently disseminated.

RESULTS

All of the methods used for examining the safety of antidepressants in pregnancy have some deficiencies in study design and analysis, thus reinforcing the need for accurate interpretations when discussing results. In addition, dissemination in both the scientific and lay press has been selective and therefore potentially biased.

CONCLUSION

It is critical, starting with the creators of knowledge, through to the recipients that discrepancies are resolved, as lack of clarity may impede the transfer of unambiguous evidence-based information from health care providers to patients, thus impacting decision making. For example, by implementing improved (KT) strategies, a pregnant, depressed woman, will be empowered to make a rational evidence-based decision regarding whether or not she should take an antidepressant during pregnancy.
