Clinical Trial Summary

With time most people with Parkinson's disease (PwP) develop fluctuations in motor symptoms in relation to medication intake. The prevalence may be both under and overestimated as it is based on history rather than observation. Patterns in fluctuations are difficult to determine and it has been demonstrated that every 30-minute diaries need to be kept for 10 days or more to safely represent fluctuation patterns. The Parkinson Kinetigraph (PKG) is an automated system that is carried passively and provides similar information after wearing the device for 6 days. Clinical experience is that most patients agree that results are representative to their experiences. It is not known if using the PKG routinely at any stage of PD will change management of the disease. The hypothesis of this study is that providing PKG information to neurologists will lead to a more active management that may improve outcome in PD patients.

Description:

Patients that have previously not performed a PKG recording will be recruited from the WestPORTS community based cohort of outpatients with PD in West Sweden. The WestPORTS study includes self-assessments like PDQ8 and NMS-Q as well as PKG recordings. On inclusion in WestPORTS-Int subjects will be randomized by minimization for age, gender and disease duration into one of two study arms. In the intervention group the PKG recording of the subject will be made available, together with a summarized interpretation, to the subject's regular neurologist/geriatrician before the next scheduled visit/contact. The neurologist will also be provided with PDQ8 and NMS-Q responses. In the control group only PDQ8 and NMS-Q responses will be available to the treating neurologist/geriatrician.

At the next regular visit/contact the physician will fill out an assessment of the state of the patient, whether stable or in need of change in management. Any contraindications to changed management will be noted and the decision to change or not change management will be recorded as the primary outcome of the study. Secondary outcomes are the patient reported experience of outpatient care according to a modified version of the Generic Short Patient Experiences Questionnaire (GS-PEQ), as well as patient reported (PDQ8, NMS-Q, PRO-PD, EQ5D5L) and PKG outcomes at a time point three months later.

Change of management is defined as any of the following:

1. Adding or stopping a dopamine agonist, COMT- or MAO-inhibitor, anticholinergic or amantadine.

2. Fractionation or de-fractionation of the current daily levodopa dose

3. Change of current Levodopa Equivalent daily dose by 15% or more

4. Start or stop of night medication

5. Referral for device assisted therapy (LCIG, apomorphine pump or DBS)

Actual change of management (as opposed to decision to change) will be documented by retrospective review of medical records and prescription records. This will be a secondary measure.

Related Conditions & MeSH terms

• Parkinson Disease

Intervention

Device:
• Parkinson KinetiGraph
The Parkinson Kinetigraph (PKG) is a wrist-worn accelerometer shaped as a watch. It records spontaneous movements and for every two minutes provides a bradykinesia score and a dyskinesia score. Furthermore it analysis movement for tremor-like episodes and registers the time with tremulous movements as well as time with extreme immobility suggesting sleep. The device can be programmed with drug intake times and provide a reminder signal. Intake of drug can be indicated on the device.

Other:
• Self assessment
Administration of self assessment questionnaires are made within 2 weeks from starting a PKG recording. The assessments are Parkinson Disease Quality of life 8 question short version and the Non Motor Symptom in Parkinson Disease Questionnaire.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Decision to change management	The decision to change management of Parkinson's disease as reported by the treating physician.; Change of management is defined as any of the following: Adding or stopping a dopamine agonist, COMT- or MAO-inhibitor, anticholinergic or amantadine.; Fractionation or de-fractionation of the current daily levodopa dose; Change of current Levodopa Equivalent daily dose by 15% or more; Start or stop of night medication; Referral for device assisted therapy (LCIG, apomorphine pump or DBS)	On first regular contact, RC, (telephone or visit) wich takes place within four months after PKG-recording
Secondary	Actual change of management	A retrospectively verified (medical and prescription records) change in management of PD as defined in the primary variable	Change should take place within 4 weeks from the RC.
Secondary	Patient Reported Experience of Care	A modified version of Generic Short Patient Experiences Questionnaire (GS-PEQ), Sjetne et al 2011 will be used. The modified questionnaire has 13 questions that are answered with a 5 grade Likert scale and a 5 grade Likert scale describing the importance of each question. Items will be analyzed separately as well as as summary scores	The assessment will be made within 3 days from the first RC after PKG-recording,
Secondary	PRO-PD score at 3 months after the first regular visit	The Patient Reported Outcome in PD web questionnaire will be reported as summary score as well as per symptom domain.	The assessment is made 3 months after the RC.
Secondary	PDQ-8 score at 3 months after the first regular visit	The 8 question version of Parkinson Disease Quality of Life Questionnaire. Reported as index score (0-100%)	The assessment is made 3 months after the RC.
