Method:

The research was experimental, prospective; the study period was 3 months (January-March 2021); the inclusion criteria for the study were drugs from the clinic's basic list of drugs that were LASA and the medication errors caused by these. LASA error prevention strategies were implemented; the medication errors presented before and after the implementation of the strategies were quantified and compared.

Results:

In the pre-implementation stage of the strategies, 24,300 medications were dispensed, among which there were 80 (0.33%) medication errors due to LASA medications. In the post-implementation stage, 23,760 medications were dispensed, and 48 (0.20%) medication errors occurred due to LASA medications, showing a significant reduction (P-valor: 0.0366314; IC: 95%). Medicines with the same active ingredient and different concentrations were those with the highest incidence of medication errors in the Pharmaceutical Service, with 37 errors in the pre-implementation stage and 19 errors in the post-implementation stage.

Conclusion:

The reduction in the rate of medication errors was 40% after implementing the proposed strategies, which demonstrates their effectiveness and their potential to offer a safer and higher quality care to patients, at low cost.
