Quando a cor ajuda

Abstract

ObjectiveTo reduce the inappropriate identification of eye drops, through the use of different colors.MethodsA group of 34 healthy volunteers was presented to two groups of four eye drops each. All eye drops were placed in identical, unlabelled vials. In one group, all four eye drops were transparent. In the other group, each had a different color. A number was assigned to each eye drop, and the volunteer was asked to identify it by color. We measured the correct index in the identification of the eye drops of the two groups.ResultsThe volunteers had a level of education from incomplete junior school to complete graduate course, with 16 males (48%) and 18 females (52%), age range of 21 to 87 years. The success rate in the group of colored eye drops was 88% and, in the group of transparent, 24%.ConclusionThe use of colorings in eye drops can help distinguishing the vials and preventing misidentification.

In search of disambiguation: development of eye drop bottle sleeves to aid in identification and survey among possible users. A cross-sectional study

“…One study tested the impact of color differences to help in identifying eye drops and showed that there was a 64% improvement in correct identification of medications based only on analysis of the color of the substance of eye drops from identical bottles. 32 In the present study, we detail the idealization and development of multisensory sleeves and evaluation of the acceptance of this new method to help reduce the risk of confusion between eye medications. Misuse of ocular medications is a subject that has only been poorly explored so far, but it is of great importance and needs to be addressed so that more solutions are proposed for increasing the safety of users.…”
