Abstract: ObjectiveTo discuss the current situation and characteristics of the common medication errors of our hospital and provide reference for clinical safe drug use. Methods69 cases of medication errors reported in the five years of 2011~2015 in our hospital were analyzed. EXCEL table was used to summarize the data, according to the main aspects of the patients' general conditions, error category classifications, the factors that cause error, the content of the error and the position of the person who caused errors.We also summarized and analyzed the error category classifications, error factors, the content of the error and the position of the person who cause errors. Category A is potential error. Category B, C, and D are mild ME which didn’t do harm to patients. Category E, F, G, H and I are severe ME which cause harm to patients even to death. ResultsThere were 29 male and 40 female patients with medication errors in the 69 cases. The youngest patient was at the age of 15, the oldest 82 years old. The mean age of the patients was 41.61. 50.72% of the error drugs had dispensed to the patients. 21.74% of the patients had used the wrong drug. There were more grade B and C errors in the error category classification. In the extent of damage to patients, 97.11% was of no obvious injury, the prescription error was of the most in the factors that cause errors, accounting for 65.22%.In the specific content of the error. The rate of drug dosage error was the highest, accounting for 28.99%. In the aspect of the positions of who had caused errors, the number of nurses was 0, the vast majority were physicians and pharmacists. ConclusionThe vast majority medication errors of our hospital didn’t bring harm to patients, but many potential risk factors brought hidden trouble to patients on medication safety. We should strengthen the management of medication errors, encouraging the doctors, nurses, pharmacists and information personnel monitoring the medication errors to minimize the occurrence of medication errors.
