Evaluation of the impact of pharmaceutical orientation given to patients on prescribed drugs

Abstract

The rational use of drugs is considered one of the key elements recommended by the World Health Organization, the absence of which can lead to consequences such as adverse reactions, decreased drug efficacy, economic losses for the government and/or individual, drug interactions, and worsening of the patient's clinical condition. The pharmaceutical orientation service that involves this context has been discussed by few studies, and the use of a validated instrument to demonstrate the impact of providing pharmaceutical guidance to patients on prescribed drugs is considered interesting and constitutes the objective of this work. The methodology used was a cross-sectional study conducted in a Primary Care Center in Diamantina, MG. A questionnaire was used to measure the patient's level of knowledge about their medications before and after receiving pharmaceutical guidance. After pharmaceutical orientation, there was a decrease in the percentage of users who did not know about their medications (73.2%; n=93 to 33.9%; n=43) and an increase in the level of sufficient knowledge (14.2%; n=18 to 18.9%; n=24) and excellent knowledge (11.0%; n=14 to 47.2%; n=60). There was an increase in users' knowledge of all the items that make up the questionnaire. Pharmaceutical orientation had a positive impact on patients' knowledge about their medications and constitutes an essential practice for the Rational Use of Medications.
