Session Title: Parkinsonisms and Parkinson-Plus
Session Time: 1:45pm-3:15pm
Location: Agora 3 West, Level 3
Objective: We evaluated the impact on routine treatment decisions of using the Parkinson’s KinetiGraph(PKG) to provide objective patient information
Background: Continuous objective measurements using wearable technology may help better understand an individual’s daily experience of fluctuating Parkinson’s disease.
Method: A computer-based service evaluation template was used by seven British centres using the PKG in their clinical practice. Clinicians could use the PKG whenever they felt it could bring clinical value. The impact of using the PKG was assessed by comparing the clinician’s prediction of the likely next step prior to PKG testing with the clinical decision after reviewing the PKG results.
Results: A total of 256 completed evaluations were collected of which 209 provided information about the impact of the PKG test on clinical decision making. The most frequently given reasons for performing a PKG were ‘Increased symptoms’and ‘wearing-off.’Information from the PKG confirmed initial clinical judgement in 54.5% of cases and provided additional information to inform the clinical decision in 45.5% cases. Changes in decision making included ten patients where the PKG results prompted a treatment change when clinicians initially predicted no changes were necessary, and 15 patients who went on to receive advanced therapies where oral medication titration had initially been considered. Conversely, information from the PKG test prompted clinicians to try other options in 18 patients originally considering advanced therapies. Patient feedback on the technology was favourable, with 98% of patients reporting a positive/neutral user experience.
Conclusion: Our results suggest that access to objective, detailed information obtained by PKG can change the next clinical decision. The PKG device was acceptable to patients.
