Abstract
Background: Psoriasis is an autoimmune disease that can pose a significant public health problem and contribute to rising health care costs, affecting people’s quality of life and ability to work. Aim: To evaluate the effect of educational intervention on outcomes of patients with psoriasis. Design: A quasi-experimental research design was utilized. Setting: This study was conducted at the Dermatology, Venereology, and Andrology department and outpatient clinics at Mansoura University Hospital. Subject: A purposive sample of 70 adult patients diagnosed with psoriasis was selected and divided randomly into two equal groups. Tools: Four tools were utilized in this study; Tool (I): A structured interview questionnaire which consisted of two parts; Part (1): Demographic characteristics and health relevant data, Part (2): Psoriasis Knowledge Questionnaire. Tool (II): Patients’ reported self-care practices checklist. Tool (III): Modified 12-Item Medication Adherence Scale. Tool (IV): Dermatology Life Quality Index (DLQI). Results: The findings revealed that after implementation of the educational intervention, study group had higher levels of knowledge than the control group with a statistical significance difference between both groups (p<0.001). Also, there was an improvement in the study group’s self-care practices and medication adherence levels, with a statistical significance difference between both groups (p<0.001). Furthermore, the total mean score of DLQI was significantly better in the study group in comparison with the control group. Conclusion: Educational intervention has a positive effect on psoriatic patients’ knowledge, self-care practices, medication adherence, and quality of life. Recommendations: Availability of a standardized colored booklet about psoriasis for patients. The educational intervention should be involved in the routine nursing management plan for patients with psoriasis.
