Abstract

Introduction : Although drug interaction  (DI)  pop-up was  alert  from  automatic  drug interactions warning  system  in  the  prescribing process, it can be overridden by the  prescribers. In addition,  it cannot  detect DI  from  different  prescriptions.  The  objectives  of  this  study  were  to measure  DIs  with major and  moderat  severit  in the same  prescriptio  and  to  identify  DIs  with major  severity  from  different  prescriptions. Methods: Ou  patien  prescriptions  from  January  1  to December 2015 were searched for DIs from the same prescription and different prescriptions.  Drug® Interaction  Facts 2009  was  used  as  a  reference  to  identify  and  classify  DIs  with  major  and moderate  severity.  Data  were  analyzed  by  descriptive  statistics. Results: Among  173,746 prescriptions, major and moderate severity DIs from the same prescription were observed in 1,379 (7.94  episodes/per  1,000  prescriptions)prescriptions  and  11,516  (66.28episodes/per  1,000 prescriptions) prescriptions respectively. For  DIs  with major  severity  from different  prescriptions,  the most  common  was  simvastatin  and  warfarin  with  a  frequency  of182episodes (13.47  episodes/per 1,000 prescriptions) from 13,511prescriptions. Conclusion: Although automatic DI warning is active in the prescribing process, DIs with major and moderate severity from overriding automatic DI warning system  and  DIs  with  major  severity  from  different  prescriptions  were  still  observed. Therefore, monitoring system should be implemented to follow up these potential DIs to support patient safety.
