Beliefs about Medicines among a Sample of Iraqi patients with Psoriasis

This study aimed to evaluate beliefs about use of medications for a sample of Iraqi psoriasis patients, and to examine the association between these beliefs and selected patient's related factors.

This cross-sectional study included 300 patients with diagnosed psoriasis. Participants were recruited at the center of Dermatology and Venereology, Medical City in Baghdad, the capital city of Iraq. Patients' mean age was 35.15years (±10.54). Beliefs about medicines were measured by the Arabic version of Beliefs about Medicines Questionnaire.

Most the patients (76.7%) had strong beliefs in the need (acceptance beliefs) for their psoriasis medicines (specific-necessity score higher than specific-concern), whereas 15.0% of patients had specific-concern score higher than specific-necessity and 8.3% of patients had specific-necessity score equal to specific-concern. At the same time, 74.4% of the patients believed that the medicines disrupt their lives and (35.6%) of them had concerns about the possibility of becoming addicted on these medicines. Many other patients were worried about the long-term consequences of the medicines (58.7%). In addition, 31.0% of the participants believe that all medicines are poisoning, and that they do more harm than good. Finally, many of the participants believed that physicians prescribe too many medicines (46.7%), and they can minimize the number of prescribed medicines by spending more time with their patients (32.6%).

Female gender and longer disease duration have direct association with specific necessity, while psoriasis severity has a direct association with specific concern. In conclusion, Beliefs about medications and habit strength are important modifiable drivers to enhance adherence and clinical outcomes in the control of psoriasis.
