บทคัดย่อ

The objective of this quasi-experimental study was to study the effectiveness of the prescribing system to reduce medication errors by applying medication reconciliation in transfer phase; discharge phase (inpatient medication system) to follow up phase (outpatient medication system). Data had been collected before implemented this process for 3 months (control group) and after the implementation 3 months (study group). Two groups’ medication errors were compared by chi-square statistics (95% CI, alpha = 0.05). The population were hypertension patients and diabetes mellitus patients who were discharged at Suanphung hospital and came to follow up in the outpatient system. We collected total unit of the population because the population were small. The result presented after medication reconciliation process had been implemented revealed that medication error rates found among patients in the study group were significantly less than those in control group (p < 0.001). Medication error rates decreased 26.5 % from 35 per 109 patients to 6 per 107 patients. Most of the defects were bound to omission errors, following by wrong dose errors. Development of prescribing system (by applying medication reconciliation) clearly improved medication errors in follow up patients.
