Objective: To explore the scope of the PRIMS assessment in People with Parkinson’s (PwP), including symptom severity rating, assessment time, individual assessment item completion and adverse report monitoring.

Background: Assessment of motor symptoms of Parkinson’s disease (PD) is largely based on clinical observation and validated tools, such as the Movement Disorders Society-updated version of Unified PD Rating Scale (MDS-UPDRS) Part III. Given the limited time for clinical consultations, PwP do not often receive unified and consistent assessment, which can potentially lead to inadequate management. Technology-based, automated assessment of motor function could offer a possible solution to this key unmet need. Parkinson’s Remote Interactive Monitoring System (PRIMS) largely follows MDS-UPDRS Part III structure, providing a holistic assessment of motor symptoms and can be conducted outside of the clinical visit, along with vitals check ahead of the appointment.

Method: A prospective data collection (n=50) conducted across two sites in Newfoundland in accordance with a National Research Council of Canada Institutional Review Board approved study protocol (2023-158) includes a PRIMS assessment (16 items as per MDS-UPDRS Part III), a certified clinician –based motor assessment using MDS-UPDRS Part III and a collection of basic demographics. Time taken to complete both PRIMS and MDS-UPDRS Part III, item completion rate and basic demographics as well as monitoring of all adverse events is collected for each participant.

Results: We aim to report on basic aspects of completing the PRIMS assessment by people with a clinically diagnosed PD, across all stages. We also aim to report on rate of completion of all items and on any adverse events observed in this initial data collection. We also aim to report on the need for assistance during the assessment.

Conclusion: PRIMS technology offers an automated assessment of a number of motor symptoms assessed by the MDS-UPDRS Part III, with a significantly different need for clinical assistance, potentially offering a robust solution to assessing symptoms ahead of the clinical visit, consequently increasing the time for physician to spend on focusing on the symptoms PwP find most bothersome. Further research is needed to explore feasibility and efficacy of the PRIMS system in research and clinical practice.
