Assessment Of The Adequacy Of Counselling Regarding Reproductive-Related Issues In Women Of Childbearing Age On Anti-Epileptic Drugs

Background: The use of anti-epileptic drugs (AEDs) in women of childbearing age (WCBA) necessitates careful counselling regarding reproductive-related issues.Aim: (i) To compare documentation of appropriate counselling regarding reproductive-related issues in WCBA prescribed AEDs for non-epilepsy vs. epilepsy indications, and (ii) to examine whether the frequency of counselling improved after introduction of 'standardized typed advice'.Design: Retrospective audit and quality assessment and improvement programme.Methods: We analysed medical records of all WCBA prescribed gabapentin, pregabalin, topiramate, valproate or carbamazepine by a general neurology clinical service before (Study period A) and after (Study period B) introduction of standardized typed passages regarding potential teratogenicity interactions with hormonal contraception at a university teaching hospital. The chi(2) test or the Fisher's exact test was employed, as appropriate.Results: In WCBA prescribed AEDs for non-epilepsy indications, documentation of appropriate counselling regarding potential teratogenicity improved from 49% (17/35 patients) in Period A to 79% (27/34 patients) in Period B (P=0.008). The frequency of counselling regarding teratogenicity was higher in patients prescribed AEDs for epilepsy compared with non-epilepsy indications in Study period A (100% vs. 49%, P=0.002), but was no longer significantly different in Study period B (86% vs. 79%, P=0.64). Documentation of counselling regarding potential interaction of enzyme-inducing AEDs with hormonal contraception did not significantly change between study periods.Conclusion: Significant improvements in documentation regarding potential teratogenicity of AEDs prescribed for non-epilepsy indications can be achieved by introducing standardized, typed passages copied to patients. Such a practice change is practical and widely applicable to neurological and non-neurological practice worldwide.
