The Relationship Between Health Literacy and the Rational Use of Medicines Among Individuals with Chronic Diseases

INTRODUCTION: This study aimed to establish the connection between health literacy and the appropriate use of medications among individuals suffering from chronic diseases.
METHODS: This descriptive and correlational study examined individuals with at least one chronic disease who presented to family medicine units in the Bucak district of Türkiye. The required sample size was calculated at 95% confidence and a 5% margin of error, and 386 participants were needed. Ultimately, data were collected from 488 participants. Data were obtained using the 'Health Literacy Scale' and the ' Rational Use of Medicines Scale'.
RESULTS: A mean score of 35.89±5.38 was achieved on the rational use of medicines, indicating a moderate level of awareness. The mean Health Literacy Scale score was 104.66 ± 15.49, indicating a high level of health literacy among participants. A test of the connection between health literacy and sensible drug use showed a strong link (r=0.60, p<.001). Health literacy and rational use of medicines scores differed significantly according to age, educational status, and occupation (p<.001).
DISCUSSION AND CONCLUSION: Increased health literacy among people with chronic diseases positively influences rational use of medicines behaviours. In this context, the implementation and dissemination of education programs and counselling services aimed at improving health literacy in primary healthcare settings are recommended to promote rational use of medicines, support treatment adherence, and reduce preventable medication-related problems.
