Using Redcap to Support the Development of a Learning Healthcare System for Patients with Multiple Sclerosis.

Multiple Sclerosis is a neurodegenerative disease which shows different phenotypes making difficult for clinicians to make short-term decisions related with treatment and prognosis. Diagnosis is usually retrospective. Learning Healthcare Systems (LHS) can support clinical practice as they are devised as constantly improving modules.

Amyotrophic lateral sclerosis in Catalonia: a population based study.

Our objective was to determine the incidence and clinical-epidemiological characteristics of an ALS cohort patient in Catalonia (Spain). We conducted a population based registry for a three-year period (1999-2001) in Catalonia (6,361,365 inhabitants) using several sources of information. The original El Escorial diagnostic criteria (1994) for ALS were applied for the classification of patients.
