Erros de medicação cometidos por pacientes assistidos por consultas farmacêuticas em unidade de saúde de Curitiba

Objective: To investigate medication errors committed by users of Primary Health Care in Curitiba, Paraná. Methods: This was a descriptive and retrospective observational study. Data were collected from electronic medical records and pharmaceutical consultation forms of patients seen at three Health Units between July and December 2021. The variables of interest were the number of patients assisted, sociodemographic profile, treated diseases, frequency of medication errors, and types of errors committed. Results: Among the 116 patients assisted, the majority were female (54.3%), aged between 61 and 70 years (34.5%), white (77.6%), with complete secondary education (26.7%), and undergoing treatment for type 2 Diabetes Mellitus (98%). Of this total, 83% committed some type of medication error. The most frequent errors were dose omission (45%), improper storage (32%), and incorrect administration frequency (17%). Conclusion: Most of the errors involve poor pharmacotherapy management by the users, highlighting the need to intensify health team actions in providing guidance to patients regarding medications. The development of strategies to support patients in managing their pharmacotherapies is proposed, along with the recognition of the pharmacist as a key professional in the management of users’ pharmacotherapeutic care.
