Understanding treatment decisions from the perspective of people with relapsing remitting multiple Sclerosis: A critical interpretive synthesis.

BACKGROUND

Multiple Sclerosis (MS) is a chronic inflammatory demyelinating disorder of the central nervous system that mainly affects young adults. While there is no cure for MS, disease modifying treatments (DMTs) reduce the relapse rate and partial accrual of disability. More effective DMTs may have higher risks including life-threatening infections or secondary autoimmunity. The complexity and novelty of available treatments cause challenges for clinicians when prescribing treatments and for people with MS (PwMS) when deciding what trade-offs they are willing and ready to make.

OBJECTIVE

To explore the experience of people with relapsing remitting MS (PwRRMS) and their perspectives in choosing treatments.

METHODS

Critical interpretive synthesis was employed to review and synthesis the published literature. Eighty-three publications were selected in a multi-step systematic process.

RESULTS

Findings are presented in four interrelated areas: the influence of the clinical evidence-base in decision making; the meaning of DMT efficacy for PwRRMS; the influence of models of decision-making and information acquisition practices in PwRRMS; and the importance of psychosocial dimensions in DMT decision making. Synthesis of the findings revealed that alongside medical and individual reasoning, contextual circumstances play an important role in making treatment decisions.

CONCLUSION

This review identifies and explains the importance of diverse contextual circumstances (clinical, social, psychological) that are important for PwRRMS when making treatment decisions. The findings demonstrate the importance of eliciting, understanding and addressing such contextual factors.
