The impact of motivational interviewing on self-perceived burden in patients receiving therapeutic plasma exchange

Background: Autoimmune disorders and neurodegenerative disorders take a physical and emotional toll on patients that undergo therapeutic plasma exchange (TPE) treatments. Previous literature has shown that these patients may feel a greater sense of self-burden. Motivational Interviewing (MI) is a technique used in various settings that has the potential to decrease feelings of self-burden. MI for patients who receive TPE has not been tested. The purpose of this study was to examine the impact of MI in patients with a neurodegenerative diagnosis (eg, transverse myelitis, myasthenia gravis, multiple sclerosis, and chronic inflammatory demyelinating polyneuropathy) that are undergoing TPE treatments. Methods: This was a prospective, non-randomized, longitudinal study of the impact of MI with patients at high risk of sense of self-burden who underwent apheresis treatments. Consented patients underwent three to six MI sessions with a trained clinician. Patients completed a self-report baseline and post-test of self-perceived burden. Results: Thirty participants consented to the study; 27 were included in the analysis. The Self-Perceived Burden Scale scores were significantly higher at baseline (m = 26.2) when compared to scores post MI sessions (m = 21.48, P <.05). The number of MI sessions (3, 4, 5, 6 sessions) did not significantly impact the outcome score (r² = 0.001; P =.901). Conclusion: MI is a straightforward technique that is feasible and shown to be effective to be used by bedside clinicians while working with patients who receive TPE to decrease levels of self-perceived burden.
