Clinical Parameters and Tools for Home-Based Assessment of Parkinson’s Disease: Results from a Delphi study

Abstract

Abstract.Background: Parkinson's disease (PD) is a neurodegenerative disorder with fluctuating symptoms. To aid the development of a system to evaluate people with PD (PwP) at home (SENSE-PARK system) there was a need to define parameters and tools to be applied in the assessment of 6 domains: gait, bradykinesia/hypokinesia, tremor, sleep, balance and cognition. Objective: To identify relevant parameters and assessment tools of the 6 domains, from the perspective of PwP, caregivers and movement disorders specialists. Methods: A 2-round Delphi study was conducted to select a core of parameters and assessment tools to be applied. This process included PwP, caregivers and movement disorders specialists. Results: Two hundred and thirty-three PwP, caregivers and physicians completed the first round questionnaire, and 50 the second. Results allowed the identification of parameters and assessment tools to be added to the SENSE-PARK system. The most consensual parameters were: Falls and Near Falls; Capability to Perform Activities of Daily Living; Interference with Activities of Daily Living; Capability to Process Tasks; and Capability to Recall and Retrieve Information. The most cited assessment strategies included Walkers; the Evaluation of Performance Doing Fine Motor Movements; Capability to Eat; Assessment of Sleep Quality; Identification of Circumstances and Triggers for Loose of Balance and Memory Assessment. Conclusions: An agreed set of measuring parameters, tests, tools and devices was achieved to be part of a system to evaluate PwP at home. A pattern of different perspectives was identified for each stakeholder.

5-2-1 Criteria: A Simple Screening Tool for Identifying Advanced PD Patients Who Need an Optimization of Parkinson’s Treatment

“…Indeed, changes in QoL has been chosen as the principal variable in some studies with PD patients selected for receiving a second line therapy [20,21] and the use of PDQ-39 in routine care for PD has been suggested [22]. However, although some criteria have been proposed with the aim to define advanced PD [23][24][25], in many cases the criteria are not useful in daily clinical practice because their application is time-consuming and also because the concept of PD is too broad [26]. erefore, a quick screening tool that identifies which PD patients are worse and need optimized treatment, including possibly a second line therapy, would be ideal.…”

Developing consensus among movement disorder specialists on clinical indicators for identification and management of advanced Parkinson’s disease: a multi-country Delphi-panel approach

“…The Delphi methodology was selected as the approach for this study given the large body of published evidence of the use of Delphi methods in clinical practice and health research to explore topics in healthcare that have not been previously examined [25][26][27] . The…”

Monitoring Parkinson’s disease symptoms during daily life: a feasibility study

“…An ESM app, the Psymate, was downloaded and installed on the smartphone of the participants. We developed a specific ESM questionnaire, based on literature discussing relevant symptoms and items for monitoring PD at home 28,29 and based on patient and clinician interviews about relevant symptoms and items for PD monitoring at home. During the measurement period, participants were asked to complete a morning (five questions) and evening questionnaire (eight questions) which were identical on all days and which were available in the morning and evening (Supplementary Fig.…”
