Abstract

BACKGROUND:

The participation of neurologists and patients in studies on the effectiveness and safety of newly authorized drugs in multiple sclerosis (MS) is insufficient. Monthly online self-assessments using patient-reported outcomes may help in short-term monitoring of neurological changes and side effects.

OBJECTIVE:

Investigate in relapsing-remitting (RR) MS patients the adherence to monthly online self-assessments after the start of disease modifying treatment.

METHODS:

Observational study in 39 neurological departments in The Netherlands. Patients starting glatiramer acetate treatment were instructed to complete online the Modified Fatigue Impact Scale 5-item version and the 8-item Leeds Multiple Sclerosis Quality of Life scale every month during 1 year (T0 toT12).

RESULTS:

Sixty-three investigators included 163 analyzable patients. At T3, 148 (90.8%) patients had completed all questionnaires; at T6, 142 (87.1%); at T9, 133 (81.6%); and at T12, 123 (75.5%). Eight (4.9%) patients did not complete any questionnaire. Median values for inter-assessment intervals ranged from 32 to 34 days (first quartile [Q1] 30 days, third quartile [Q3] 41 days), and the final assessment was at 417 days (median: Q1 385 days, Q3 480 days). Forty-three (26.3%) patients completed the questionnaires at all time points (completion adherent) with their final assessment within 30 days after the scheduled T12 (interval adherent). Eighty (49.1%) patients were completion adherent, but not interval adherent. Forty (24.5%) patients were not completion adherent, as they discontinued assessments prematurely. Men were more interval adherent than women (47.5% vs 20.0%; P = 0.001).

CONCLUSION:

The observation that three out of four (75.5%) RRMS patients completed two short questionnaires at all monthly time points during 1 year after the start of disease modifying treatment suggests that intensive online monitoring in this patient group is feasible. As only one in five (19.6%) patients adhered to the time intervals between self-assessments, measures are needed that improve the timely completion of questionnaires.
