Impact of Pharmacist-Led Intervention on Adherence, Quality of Life, and Self-efficacy Among Iraqi Patients with Systemic Lupus Erythematosus

Background: The prevalence of systemic lupus erythematosus (SLE) patients is rising in Iraq. Adherence to medications among SLE patients remains a significant problem, and nonadherence can lead to decreased quality of life (QoL) and poor disease outcomes. Objectives: To determine the efficacy of pharmacist interventions in enhancing medication adherence, QoL, and self-efficacy among SLE patients. In addition, to assess the influence of pharmacist intervention on the uptake and willingness to take the flu vaccine among patients with SLE. Methods: A pharmacist intervention study was conducted at the Rheumatology Unit in Baghdad Teaching Hospital. Participants obtained educational counseling and a self-assembled booklet. Each patient participated in two sessions; the initial session was conducted immediately after the completion of a baseline evaluation of adherence, QoL, and self-efficacy through a face-to-face interview, and the second session was held one month later. Each session continued for approximately 25-35 minutes. The evaluation of adherence, QoL, and self-efficacy was obtained again at the end of the study. Results: The study recruited 90 patients with a mean age of 34.29±9.9 years. The mean scores of adherence, physical, social, and psychological domains of QoL, and self-efficacy were significantly enhanced after the intervention. Still, the environmental domain of quality of life is non-significantly changed. Also, after the intervention, a significant rise was seen in the uptake and willingness to take the flu vaccine. Conclusion: Pharmacist-led intervention significantly improved medication adherence, quality of life, self-efficacy, and the uptake and willingness to take the flu vaccine among SLE patients.
