Background and importance Narcotic drugs require a special control and monitoring by the Pharmacy Service (PS) to ensure their correct storage and dispensing. An automated dispensing system could promote a safer and more efficient process.

Aim and objectives Describe and analyse drug replacement times and errors through a manual process versus an automated process.

Material and methods A prospective 1-month observational study, divided into two periods, was carried out. In the first period (15 days), the replacement of Hospitalisation Units Dispensing System (UH-DS) was carried out through a manual process guided by the user. In the second period (15 days), after the implementation of a new automated Pharmacy Service Dispensing System (PS-DS), the replacement was carried out by computer integration between UH-DS and PS-DS.

Times were described through medians and interquartile ranges (IQRs) and were compared using a Mann–Whitney U test. Replacement errors were described through the percentage of errors with respect to the total number of units replaced and were compared using a Chi-square test.

Results A total of 1991 units were dispensed: 1082 units through the manual process and 909 units through the integrated automated process. The total time taken was 16.8 s/unit (IQR 3.6) for the manual process, while for the integrated process it was 9 s/unit (IQR 2, 4) (p <0.05). The number of errors detected for the manual process was 1.57% (17/1082) compared to 0.88% (8/909) for the integrated process, which represented a reduction of 56% (p>0.05).

Conclusion and relevance The implementation of an automated process integrated with a PS-DS allowed the reduction of replacement times by 46.4%, as well as replacement errors by 56%. This improvement provides a safer and more efficient drug replenishment circuit that should be implemented in routine clinical practice.
