Decision making process in multiple sclerosis: An Argentine pilot study

There is scarce information regarding the decision-making process (DMP) in people with MS (PwMS) from Latin America.

To evaluate the DMP in Argentinean PwMS and to assess its relationship with patient preferences, and clinical-demographic characteristics.

PwMS from the patient organization Esclerosis Múltiple Argentina (n = 1275) were invited to participate in a self-administered web-based survey. Participants were asked to provide clinical-demographic information and to complete a questionnaire on their perceptions about the information provided by their physician, the Control Preference Scale, and the Satisfaction with the Decisions and Care Questionnaire, and were inquired on their preferred sources of information about MS.

The survey was completed by 379 PwMS. Most were females (67%); mean age: 40.3 (SD = 11.1) years; mean disease duration: 7.9 (SD = 7.2) years. Patients' decisional control preferred role was active in 47%, shared in 27%, and passive in 26%. A moderate concordance (weighted kappa 0.55) was observed between patients' preferences and self-reported DMP. Seventy-two percent participated in the DMP according to their preferences (concordance rates: active 66%, shared 87%, passive 51%). Most (83%) declared receiving information from their neurologists, matching their preferences (94%).

Argentinian PwMS have distinctive preferences regarding information management and decision making.
