Incompatibility

Incompatibility is an unexpected physical and/or chemical interaction between two or more substances when in a mixture, which can compromise the safety and efficacy of treatment with the product formed. Additionally, incompatibility can imply consequences that go from a simple obstruction of a catheter to an individual’s death. It is necessary that the multiprofessional team be attentive to this problem, primarily due to the lack of knowledge and the lack of training of the professionals.(28)

This study has the limitation the fact of having been conducted at a single center, with a reduced sample size, which could hinder the comparison with other realities and generalization of the results. In addition, the intervention of the investigator, in case of potential or real error, could have caused interference in the findings of the research. Nevertheless, the results of this study can contribute so that individual failures or those in the process of preparation and administration of medications are identified, and that measures for prevention are implemented, such as in training and permanent education of the team, which results in increased quality of care and safety of the patient.
