Evaluation of drug-drug interaction in the EHR data
type: CreativeWork
description: Drug–drug interactions (DDIs) caused by co-prescriptions can alter the effectiveness of treatment or occurrence of adverse drug events (ADEs). Also, it in itself could be life-threatening to patients. An electronic alert for DDI is one of the most successful components of electronic medical record (EMR) systems for reducing the DDI-associated ADEs by providing alerts and/or detailed information at the moment of prescribing. The primary objectives of this study is to determine whether the incidence of alerts for DDI and their override rates differed by admitting department (emergency department, ED; general ward, GW; intensive care unit, ICU). We also tried to reveal the difference in drug pairs causing DDI alerts and reasons for alert overrides among the three departments by analyzing a longitudinal electronic health record (EHR) data and its alert and logging system of a teaching hospital. The risk of DDI among admitting departments were compared and analyzed the cause of prescribing which is possible to occur DDI with the purpose of providing baseline knowledge for acceptable clinical decision support system (CDSS). This is a retrospective cohort study using a tertiary hospital in Korea. The participants of this study are all patient who were visited/admitted into ED, GW or ICU, from September 1, 2009 to March 31, 2013, incidentally. The risk for DDI alert and alert overrides were compared among admitting department (ED, GW and ICU). Also, the cause of prescribing possible DDI drugs was analyzed by manual review of all free-text record recorded by physicians. The incidence of DDI alert is 6.4% (0.13 person-year) in total, order by 18.4% in ICU, 6.3% in ED and 6.2% in GW, respectively. After adjusted in age, gender, age-adjusted Charlson’s comorbidity index (CCI), administration of chemotherapeutic drug, mean number of drug per day, and transfer from other department, the risk of DDI alerts in ED (HR, 1.923; 95% CI, 1.823-2.028) and in ICU (HR, 1.845; 95% CI, 1.635…
