TELESM-edu.Nursing: a Personalised Nursing Intervention for People With Multiple Sclerosis (TELESM-edu)

Experimenteel: Telenursing Education Program with Video Pills and Teleconsultations

Participants assigned to the intervention group will receive, in addition to standard care, a personalised six-month telenursing educational programme including video pills and nurse-led teleconsultations. Six video pills (5-8 minutes) will be sent monthly via email before each teleconsultation and will cover key aspects of multiple sclerosis management. Materials will be developed using Patient and Public Involvement principles with a multidisciplinary team and patient representatives. The programme includes six monthly teleconsultations via a telemedicine platform to assess understanding, support symptom and disability management, identify informational needs, and promote adherence (20-30 minutes each). Prior to the intervention, participants will receive telephone support to access the platform. Teleconsultations will be tailored to health literacy levels using appropriate communication strategies.

Ander: TELESM-edu.nursing

The teleconsultation intervention will be tailored according to participants' health literacy (HL) levels, adapting content complexity, information load, language, interaction style, and methods to verify understanding, while maintaining consistent participation goals.

For patients with low HL, the intervention will focus on simplifying and progressively structuring information, prioritising essential and practical content. Understanding will be assessed using teach-back and Teach-to-Goal strategies. Nurses will provide supportive materials, including brochures with images, diagrams, and key messages, sent via email after each session.

For patients with adequate HL, the intervention will include more in-depth content and encourage critical discussion. Additional educational materials and reliable online resources will be provided after teleconsultations to support further learning.
