Furthermore, all providers surveyed strongly agreed that pharmacist involvement decreased time to therapy initiation and provider time spent on medication management. Clinical pharmacists play an integral role in MS patient care, particularly with facilitating medication access. Prospective studies are needed to further evaluate the contribution of clinical pharmacists in MS patient care.

Prospective studies are needed to further evaluate the contribution of clinical pharmacists in MS patient care. Fatigue is the most disabling symptom in patients with multiple sclerosis (MS). Although there is no standard tool to evaluate fatigue in clinical settings, the Fatigue Impact Scale (FIS), Fatigue Severity Scale (FSS), and Multidimensional Assessment of Fatigue (MAF) scale are popular instruments for this purpose. The aim of this study was to compare the psychometric properties of the Persian versions of these scales. One hundred thirty adult patients with MS and 60 controls participated in this study. They completed the scales on two occasions 3 days apart. Reproducibility and internal consistency were evaluated as intraclass correlation coefficients (ICCs) and Cronbach α. Convergent validity was assessed by evaluating the association of the fatigue scales with age, sex, Expanded Disability Status Scale (EDSS) score, disease duration, and sleep quality. Dimensionality was evaluated using confirmatory factor analysis. Acceptability and known-group validity were investigated. The effect size of each scale was computed. The ICC of all instruments was 0.99. Internal consistency was 0.97 for the MAF scale, 0.93 for FSS, and 0.83 f
