Evaluation of the Effectiveness of the Parkinson Specialized Teams Intervention

A pilot experiment interventional study is proposed in order to set up multidisciplinary team for Parkinson's patients at home. The aim of this study is to evaluate the effectiveness of this specialized Parkinson's team (ESPark) intervention a on the quality of life of patients with moderate to severe Parkinson's disease

Parkinson's disease (PD) and related disorders are the second most common cause of motor disability in the elderly after stroke. Progressively, the disability impacts the activities of daily living and social life of Parkinson's patients with a major impact on their quality of life. The diversity and complexity of the needs of parkinsonian patients and their caregivers justify a specific multidisciplinary approach. Several studies have evaluated the effectiveness of the intervention of such teams on the maintenance of activities of daily living and quality of life of Parkinson's patients with contradictory results. In France, the experience of specialized Alzheimer teams (ESA) based on the same concept seems to have brought positive results on autonomy and resocialization. Based on the positive experience of ESA intervention in Alzheimer's disease and in view of the data in the literature on Parkinson's disease, we would like to develop the same type of care with teams adapted to the problems of Parkinson's disease patients, which we could call ESParks, and to evaluate the effectiveness of such teams in the context of support for Parkinson's patients.
