Retrospective evaluation of prescribing pattern and utilization of antiepileptic drugs in pediatric, neurosurgery, and psychiatry wards: A comparative study to the standard treatment guidelines

Antiepileptic drugs (AED) are progressively utilized for off-label conditions other than epilepsy, like bipolar disorder and migraine. The objective of this study was to evaluate current prescribing patterns and utilization of AED in pediatric, neurosurgery, and psychiatry wards and to compare them to the standard treatment guidelines. A descriptive, cross-sectional study was conducted in Ayyub Teaching Hospital, Abbottabad from December 1st, 2018 to April 2019. Data on demographic and clinical characteristics, utilization patterns of AED, adherence to standard treatment guidelines, and frequency of potential drug-drug interactions were analyzed using descriptive statistics. Among 410 patients, 54.3% (n = 223) were male, 45.6%(n = 187) were female, and 63.7% (n = 261) were from the 1 to 18 years' age group. The majority 47.3% (n = 194) were from the pediatric ward followed by neurosurgery 28.7%(n = 118). Among the studied patients, 96.1% of them had comorbid conditions other than epilepsy alone. With regards to types of seizures unclassified seizures were the most common seizure type (59.8%; n = 245) followed by generalized tonic clonic seizures 23.4% (n = 96). In this study, the most frequently utilized AED was sodium valproate 59.0% (n = 242) followed by antiepileptic first-generation medicines were commonly used (76.3%). Although a total of 77.6% of the patients showed nonadherence to National Institute for Health and Care Excellence guidelines and 87.6% of them showed drug interactions. Findings from this study showed prescription patterns and utilization of AED in patients with epilepsy and non-epilepsy disorders which may help healthcare providers in making accurate clinical decisions.
