IMPROVEMENT – Improving the outcome in myositis spectrum diseases: core set variables harmonization and use from children to adulthood


Myositis spectrum disorders (MSDs) inclu- de a wide range of conditions deeply affecting patients’ prognosis and quality of life. Health problems related to MSDs include not only muscle (myositis), but also joints (arthritis/arthralgias), skin (typical cuta- neous lesions) and lungs (Interstitial lung disease).

The timing of onset of different MSDs’findings is generally variable and the risk of a not proper patients’ classification is very high. The myositis expert community recognizes that other steps are necessary for the clarification of different MSD patterns (in both adulthood and childhood), instrumental and laboratory tests to apply and best treatment options.

These steps are mandatory to improve patients’ survival and quality of life, paying special attention to a very vulnerable period for pediatric patients carrying a chronic illness: the transition to an adult age.

To harmonize the international MSDs registries EUMYONET and AENAS with national registries and hospital records; to create a longitudinal database to improve patients’ follow-up, treatment and prognosis.

  1. Define and reach consensus among clinicians and patients on a minimum core set of myositis spectrum disease organ-specific measures to address unmet needs, further characterise disease subsets, evolution and treatment, building on existing work in AENEAS and Euromyositis
  2. To facilitate collection of longitudinal outcome data by harmonization of national registers
  3. To collect existing patient-recorded outcome data more frequently using smartphone applications for aiding patient engagement and clinical practice/research. To use this technology for streamlining the transition between adolescent and adult care in MSDs through harmonized data collection from adult and paediatric clinicians
  4. To facilitate standardized data capture from electronic hospital records by technical integration and initiate a common technological platform for the Euromyositis and AENEAS registers



Y1: Teleconferences and ethical approvals, data collection harmonization and core set measure to share with other centers/groups, development of technologies, pilot testing of technologies in 12 sites, definition/agreement of core set, submission of LOINC definitions
Y2: Clinical data collection from registers &analysis of shared data.
Y3: Rolling out of technologies in other Research Partner sites, collection of longitudinal smartphone app data, collection of longitudinal clinic based PROM data, research partner meeting of group data shared analysis. Successful implementation of core data into an existing platform, Proof of concept that remote data system can be completed longitudinally

Interim Results

  1. A list of applicable measures has been obtained from the systematic literature review and from the analysis of existing datasets addressed to different myositis conditions.  A survey will be send to selected centers/people, in order to understand which variables can be easily collected and for identify potentially lacking aspects.
  2. The process of harmonization will start after the definition of clinical variables that should be collected.
  3. A bespoke smartphone-based app has been designed that allows collection of myositis-specific patient reported outcome measurements at high frequency (up to daily).

Patient Voice

Patients are involved in every phase of the project. Participants are invited through myositis centres and through already existing registries for myositis. Associazione Nazionale Malati Reumatici (ANMAR), Italy is involved as a patient organisation.
