| Summary: | Background and ImportanceIn 2016 therapeutic drug monitoring programme (TDMP) began for new anticonvulsant drugs (NAD) for inpatients and outpatients at our hospital. Weekly multidisciplinary meetings were held to revise out-of-range trough drug levels (TDL) on epileptic outpatients, and to make early drug adjustment interventions (EDAI) before their scheduled clinical follow-up.Aim and ObjectivesTo evaluate the impact of NAD TDMP on the activity of the Pharmacy and Neurology departments.Material and MethodsInpatientsQuantification of pharmacokinetic interventions (PI) and patients monitored between 2016-2021.OutpatientsActivity analysis between July 2017 and May 2019: TDL revision, patients monitored and number of EDAI made. TDL and EDAI percentage calculation for each drug.ResultsInpatientsAnticonvulsant drug PI were 56% of all PI (6.067 of 10.910) during the study period. PI of classic anticonvulsant drugs (CAD) decreased from 934 in 2016 to 348 in 2021 (63%). In 2021 the percentage of PI of NAD and CAD were 27% and 16% (602 and 348 out of 2.209) respectively. Levetiracetam and Lacosamide accounted for 63% (380) and 27% (163) of all monitored NAD. Regarding CAD monitoring Valproate was the most 86% (299) and Fenitoin the least 4% (15) monitored.Outpatients1.096 TDL out of 2.324 ordered were revised (47%) which belonged to 424 patients of a total of 877 monitored (48%). 273 TDL (25%) led to an EDAI, which affected 196 patients, that is 46% of revised patients and 22% of all monitored patients. Most EDAI supposed an increase or reduction of dosage, 51% and 34% (139 and 92 out of 273) respectively. Levetiracetam, Perampanel and Lacosamide were the most monitored NAD: 26% (286), 13% (145) and 10% (110) respectively, and the most EDAI-prone: 29% (79), 27% (73) and 11% (29) respectively.Conclusion and RelevanceInclusion of outpatients to TDMP allowed early drug adjustment of almost half of the revised patients.The creation of a multidisciplinary team that includes pharmacists and neurologists with a focus on active monitoring of NAD TDL might be significant to better care for epileptic outpatients.References and/or AcknowledgementsConflict of InterestNo conflict of interest |
