PRIMUS : Real World Usage for Real World Evidence of CDSS Use in Multiple Sclerosis (PRIMUS)
PRIMUS a Multi-centre, Controlled, Cluster-randomised, Open Study of Multiple Impacts of CDSS Use in Multiple Sclerosis : Real World Usage for Real World Evidence
This study evaluates a Clinical Decision Support System (CDSS), named PRIMUS, designed to support therapeutic decision-making in MS. The CDSS is based on a validated reference database integrating retrospective data from randomized controlled trials and the French national MS cohort (Observatoire Français de la Sclérose en Plaques, OFSEP). This reference database consists of synthetic data derived from these sources.
PRIMUS enables visualization of disease activity at 1 and 2 years under different therapeutic scenarios, based on clinical and MRI characteristics of patients similar to the patient of interest. The CDSS PRIMUS aims to support informed and individualized treatment decisions. Because MRI is a critical marker of disease activity previously acquired MRI scans will be reanalyzed using automated segmentation and validated by a radiologist to standardize lesion assessment across centers. The results will be displayed to the neurologist and, if appropriate shown to the patient using a dedicated viewer, and can be discussed during the consultation.
A cluster-randomized controlled trial, with hospitals as the unit, will be conducted to evaluate the impact of the CDSS on treatment decision-making in patients with relapsing-remitting MS. The primary objective is to assess whether the use of the CDSS influences therapeutic choices during clinical consultations.
The study hypothesis is that use of the CDSS will increase the proportion of high-efficacy treatments initiated or selected, compared with usual care without CDSS support.
In parallel, an optional sub-study using a mixed-methods approach will explore clinicians' and patients' perceptions of, and interactions with, the CDSS.

実験的:Consultation with clinical decision support system CDSS
Participants will undergo a consultation supported by a CDSS when initiation or modification of MS treatment is being considered.
|
The Clinical Decision Support System (CDSS) PRIMUS is a software (as medical device) designed to support therapeutic decisions in multiple sclerosis (MS) and assist clinicians during consultations in which initiation or modification of MS treatment is considered. The system uses retrospective clinical and MRI data from a reference database to generate visualizations of disease evolution over a 2-year period under different therapeutic scenarios, based on patient-specific characteristics entered by the clinician. PRIMUS does not make treatment recommendations and does not replace clinical judgment. All treatment decisions remain at the discretion of the clinician |
|
介入なし:Usual care (consultation without CDSS)
Participants will receive standard clinical care without the use of a Clinical Decision Support System (CDSS).
Treatment decisions will be made according to routine clinical practice.

Treatment decision concordance with expert recommendation
時間枠:Month 1

Assessment of concordance defined as agreement (Yes/no) between the treatment decision made by the neurologist at the end of the consultation (Month 1, with or without CDSS use) and the treatment decision recommended by an independent expert panel of experts.

Treatment Decision Concordance with Dynamic Score Recommendation
時間枠:Month 1
|
Assessment of concordance defined as agreement (yes/no) between the treatment decision made by the neurologist at the end of the consultation (M1, with or without CDSS use) and recommendations derived from a dynamic scoring system designed to guide early switching from first-line to second-line disease-modifying therapy in patients with relapsing-remitting MS.For this outcome measure, results will be reported as the proportion of participants whose treatment decision is concordant with the recommendation generated by the dynamic score (Yes/No).The dynamic score is based on predefined clinical and radiological criteria and identifies patients who may benefit from early treatment escalation to reduce the risk of relapse.The recommendation generated by the score (maintain first-line therapy or escalate to second-line therapy) will be compared to the neurologist's treatment decision.Concordance will be considered achieved if the neurologist's treatment decision matches the recommendations

Evolution of treatment decision
時間枠:Month 1
|
Assessment of concordance defined as agreement (yes/no) between the treatment decision initially considered by the neurologist at inclusion (Month 0) and the treatment decision made at the end of the consultation (Month 1, with or without CDSS use). This outcome evaluates whether the initial treatment strategy is maintained or modified between Month 0 and Month 1, including potential influence of CDSS use during the consultation |

Cost-utility analysis of CDSS use
時間枠:Month 0 to Month 10
|
A cost-utility analysis will be conducted from a societal perspective over a 10-month period : at baseline (Month 0), Month 1, and Month 10 to evaluate the impact of CDSS use. Health-related quality of life will be assessed using the EuroQol 5-Dimension 5-Level questionnaire (EQ-5D-5L). The EQ-5D-5L descriptive system includes five dimensions (mobility, self-care, usual activities, pain/discomfort, anxiety/depression), each with five response levels. Utility index values range from values below 0 (health states worse than death) to 1 (perfect health), with higher scores indicating better health status. Costs related to multiple sclerosis care will be collected over the study period (M0-M10) using patient diaries. Quality-adjusted life years (QALYs) will be estimated from EQ-5D-5L utility values and combined with cost data to perform the cost-utility analysis. |

Patient-Reported Outcomes: Multiple Sclerosis International Quality of Life Questionnaire (MusiQoL) Score
時間枠:Month 0 and Month 10
|
Health-related quality of life will be assessed using validated patient-reported outcome (PRO) instrument : the Multiple Sclerosis-specific quality of life questionnaire (MusiQoL) at baseline (Month 0) and Month 10. The MusiQoL provides a disease-specific assessment of quality of life in multiple sclerosis. The MusiQoL global index score ranges from 0 to 100. Higher scores indicate better health-related quality of life. |

|
General health-related quality of life will be assessed using the 12-Item Short Form Health Survey (SF-12) at baseline (Month 0) and Month 10. It evaluates general health-related quality of life. The SF-12 generates Physical Component Summary (PCS) and Mental Component Summary (MCS) scores. Scores generally range from 0 to 100. Higher scores indicate better health-related quality of life. |
