การประเมินระบบกระจายยาสำหรับ 1 วันในหอผู้ป่วยอายุรกรรมชาย ที่โรงพยาบาลปทุมธานี / กฤติมา ขาวละออ = Evaluation of one-day drug distribution system in male medical ward at Pathumthani Hospital / Krittima Khaola-or
To evaluate the one-day drug distribution system by comparing data obtained from the previous drug distribution system with the new system in terms of 1) number and characteristics of medication errors 2) work performance time of drug distribution system 3) number and cost of ward-stocked medicines. Opinions of health care providers involved in the drug distribution system were studied as well. Study was performed in male medical ward; patients were divided into 2 groups according to the drug distribution system used in that period. The first group was 226 patients who admitted during 1-30 September 2002 when the previous drug distribution system was provided. The second group was patients admitted during 1-31 December 2002 while the new drug distribution system was implemented. A total of 759 medication errors (MEs) were found in the previous drug distribution system which was 3.51% of total chance of errors (TCEs = 21,640), in the second drug distribution system, 203 errors were found which was 0.99% of TCEs (20,484). The number of MEs of the two systems were significantly different (p < 0.05). Transcription errors were mostly found in both systems, there were 662 errors in the previous system (87.22% of total MEs of previous system) and 134 errors in the new system (66.01% of total MEs of new system). There was no statistical difference (p =0.09) of prescribing error in the two system. The work performance time of the new system was longer than the previous one. There were significant differences (p < 0.05) on the time of transcribing process, labeling process, drug dispensing process, drug verification process and tablet dispensing (on ward) process. From the study, 25 items (23.08%) of ward-stocked medicines decreased which costed about 20,390.07 Baht (62.05%) Survey of opinions on the new system were performed in 29 health care providers involved in the drug distribution system which resulted that the new system can help decreasing medication errors, verifying between nurses and pharmacists, controlling items and cost of ward-stocked medicines. Although less medication errors were found in the new system, it increased workload to health care providers. Therefore, this new system should be developed for practical practice. Explicit explanation of the system should be performed for better understanding. Finally implementation of the appropriate drug distribution to other wards should be extended.
