Objectives:
to compare the effectiveness of the decentralized automated drug dispensing system with pockets.
Methods:
an effectiveness study based on a systematic review guided by the question: for patients admitted to hospital units, is the use of automated drug dispensing effective for reducing medication errors when compared to manual unit dose dispensing? The evidence was evaluated by the Grading of Recommendations Assessment, Development and Evaluation and the Preferred Reporting Items for Systematic Reviews and Meta-Analyses instrument, used in the report.
Results:
the sample was composed of 15 studies and none of them directly compared both technologies; however, the meta-analysis showed that there is no difference in effectiveness between them [OR 1.03 95%CI (0,12 - 8,99)].
Conclusions:
the conclusion is that the recommendation in favor of the automated dispensing system is weak.
