| Abstract | Introduction: Prescription error resulting from the handwritten prescribing system is harmful to patients and may delay hospital stay, since July 2015, the Nonghan hospital has operated an in-patient computerized prescribing system to replace of handwritten prescribing system in all wards of the hospital. The objective of this study is to evaluate the effect of a computerized prescribing system on the prescription error rate. Method: we use interrupted time series to study prescription error rate before and after implementation computerized prescribing system during July 2014 to June 2016. The two series of prescription error adjusted for seasonal rates, 12 data point variation trend of each series, were collected from medication error reports for 24 data point. We use segmented linear regression to estimate the reduction prescription error and its 95% confidence interval (CI). Results: The mean prescription error rate per month before implementing the computerized prescribing system was 66.0 per 10,000 bed days (95% CI: 49.3 to 82.8 per 10,000 bed days). After implementation of computerized prescribing system, the immediate absolute reduction of prescription error rate was significant with 39.6 per 10,000 bed days (95% CI: 18.3 to 60.8 per 10,000 bed days). There were no significant trends of the prescription error rates at before and after implementation of computerized prescribing system. Conclusion: This study has shown that the computerized prescribing system can reduce prescription errors in the inpatient wards at the acceptance level of the hospital without harmful effect on any patients. |
