Adherence to Long-Term Interferon Beta-1b Injection Therapy in Patients with Multiple Sclerosis Using an Electronic...

Area of Science:

• Neurology
• Pharmacology
• Health Informatics

Background:

• Multiple sclerosis (MS) is a chronic CNS inflammatory disease.
• Long-term treatment adherence is crucial but often challenging.
• Non-adherence leads to disease activity and increased healthcare burden.

Purpose of the Study:

• To assess the impact of a personal digital assistant (PDA) with diary function on treatment persistence and adherence.
• To compare PDA use against a traditional paper diary for interferon beta therapy in MS patients.

Main Methods:

• Prospective, non-interventional, national cohort study.
• 2-year observational period in patients recently started on subcutaneous interferon beta-1b.
• Comparison between PDA users (n=339) and paper diary users (n=330).

Main Results:

• Overall therapy persistence (dropout rate) was approximately 50% in both groups.
• Male patients showed a 10% lower dropout rate with PDA use.
• PDAs with injection reminders increased adherence by an average of 24.5 injections over 24 months.

Conclusions:

• Therapy persistence aligns with published data for observational MS studies.
• PDAs may positively influence therapy continuation, especially in male patients.
• Integrated reminder functions in electronic diaries can enhance adherence to MS therapy.
