Purpose: With the reducing hospital maintenance costs, rapid and accurate drug dispensing, and efficient management of drugs become more important, the introduction of automated dispensing cabinets (ADCs) is increasing in korea. In this study, we tried to compare between a conventional drug dispensing system and a drug dispensing system using ADC to find out the effect of reducing required time from preparation and dispensing in pharmacy to administration to the patient and on the reduction of medication error.
Methods: We compared the total number of monthly PRN injections preparation, the number of emergency reception, required time of PRN injections from dispensing to administration, and medication errors (name confusion, improper dose errors, wrong dosage-form errors and ADC errors) for PRN injections, from January to December 2018, for ADC-introduced Surgical A ward (16 beds) and non-ADC-introduced Surgical B ward (12 beds) and C ward (14 beds). The PRN injections order System of this hospital is operated by ‘split-timed reception’ that accepts a prescription at a set time and delivery it to the ward (8 times/day), ‘emergency reception’ that receives prescriptions from pharmacies by phone as needed and delivery it to the ward, and ‘ADC system’ that dispenses injections directly from a ward using an ADC. Each ward is analyzed by system and statistical analysis was performed using SPSS ver23.
Results: During the period of research, in the case of B and C ward, the time required from the dispensing to the administration of the PRN injections was shorter in case of ‘emergency reception’ (mean±SD, B: 236±356 min, C: 147±218 min) than ‘split-timed reception’ (B: 255±332 min, C: 241±296 min, p<0.05). In the case of A ward the time required for administration to the patient was significantly reduced when the injection was received using ADC(152±287 min) rather than the ‘emergency reception’(360±337 min, p<0.05). The total number of monthly PRN preparations was higher in A ward (2,378±249 cases) than in B ward (2,051±185 cases), but there was no statistical difference between C ward (2,202±364 cases, P=0.107). In the case of ‘emergency reception’ among total number of preparations, A ward (898, 3%) was less than B ward (7,745, 31%) and C ward (10,708, 41%). In the number of errors reported during the analysis period, the errors in A ward were 5 cases, which was less than those in B ward (n=7) and C ward (n=9), and the errors were name confusion(A: 1, B: 5, and C: 4) and improper dose errors (A: 2, B: 2, and C: 3).
Conclusion: The introduction of ADC has shortened drug delivery time from pharmacy to wards and improved the efficiency of drug management. In addition, the introduction of ADC has made it possible the timely administration of the drug and improved patient safety by reducing the medical errors.
