Computerized Alert Program for Patients with History of Adverse Drug Reaction in Pharmacy Service

Abstract

In the old version of the computerized alert program, space of the drug name was keyed-in one by one. Incomplete data in electronic patient medication record lead to the incidence of ordering drug that must not be ordered. Therefore, the convenience working computerized alert program for patients with history of adverse drug reaction (ADR) was developed. The aims of this study were to investigate and compare the incidence of prescribing drug that must not be ordered in patients with history of ADR, before and after the computerized alert program was implemented. The study was an action research. Data were collected from electronic medical records. Patients with history of ADR who visit the out-patient clinic from October 2017 to November 2017 and December 2017 to January 2018 were included. Chisquare test was use to compare the incidence of prescribing drugs that must not be ordered in patients with history of ADR. A total of 8,629 patients with history of ADR were included. Drugs which were found the most incidence of allergy and side effect were penicillin and enalapril 23.9% and 35.5, respectively. Rash from drug allergy was found the most (44.8%). Cough from drug side effect was found the most (32.2%). Of totals, 5,366 patients came to the hospital with 12,560 visits during the study period. After implementing the program, the incidence of prescribing drug that must not be ordered was significantly reduced from 0.81% to 0.02% (p<0.001). After the computerized alert program was developed and implemented, the incidence of prescribing drug that must not be ordered in patients with history of ADR was lowered. This alert program should be link to the hospital website to provide the multidisciplinary team service in case of working out of the hospital.
