However, it contains unpredictable risks which result in patients’ injury or death. Nowadays, patients’ safety has been noticing by healthcare professionals, especially after many serious medication reports. The issues of medication administration drew out concerns no matter in Taiwan or other nations. The most common medication error is omitting medications to patients. Nonetheless, the majority of researches used questionnaires survey to figure out the awareness and causes of medication errors. There is a few studies using chart audits to describe the medication omission. Therefore, the purpose of this study is to explore the incidence, causes, and the associated factors of medication omissions.
This research is a retrospective study through chart audits, which enrolled 300 inpatients from a medical center of Sothern Taiwan in 2013. The following statistics are used: (1) Descriptive Statistics (2) Independent-Samples t Test (3) Poisson regression by SPSS 18.0 for Windows. The results revealed that the medication omission rate is 6.2%; the duty shift affected the medication omission rate, 70 patients （50.4%）were found in the day shift, the average on each inpatient is 0.84 times of medication omission. The most common omitted medications are for gastroenteric system (21.8%), the least are for diuretics and anti-diabetic medications (5.2%). The most common route of omitted medication is via mouth (82.5%). In terms of frequency, “once-per-day” medication was the most medication omission, which accounts for 36.5%. The most common reason for omission is unknown (34.5%). From the regression analysis, we can conclude that there was positive relationship between duty shift and medication omission.
The rate of medication omission and associated factors are under investigation in this study. The findings may improve the process of medication administration and be implemented into clinical practice. The system of medication should be modified to improve the safety and the quality control for hospital managers. Medication omission could be decreased in the future as designing in-service education, monitoring medication administration, and standard procedure for healthcare system. By implementing the correction of medication administration, patient safety can be ensuring for better health outcomes.
