The Link Between the Training of Nursing Home Professionals and the Quality of Life of Residents With Parkinson's Disease

The complexity of medication treatments and the diversity of symptoms in Parkinson's disease (PD) require healthcare professionals to have specific knowledge of the disease in order to manage symptoms optimally and on an individualized basis. This becomes even more important as the disease progresses due to the evolution of symptoms into fluctuating motor and non-motor manifestations. People with PD residing in nursing homes (EHPADs) often have multiple comorbidities, making care even more complex. A lack of specific knowledge among healthcare professionals in EHPADs can expose residents to an increased risk of complications and dependence, affecting their quality of life. Additionally, the complex symptoms of these residents can create concerns for care teams, which can act as a barrier to admitting this population of elderly people into these institutions. Thus, training professionals who care for and support elderly individuals with PD is a priority to optimize the healthcare journey for people with Parkinson's.

Interventions aimed at improving care quality are often implemented without evaluating their impact or using methodologies that do not provide scientific evidence justifying their generalization. Evaluating these interventions is essential to develop effective interventions within the healthcare system, contributing both to the improvement of care quality and to health policy. These interventions should undergo an evaluation of their positive and negative effects before being generalized.

The PARK-EHPAD study aims to assess the link between the training of healthcare professionals and the quality of life of elderly individuals with PD living in EHPADs. Since 2015, the Parkinson's Expert Center (CEP) at CHU Grenoble-Alpes, in partnership with the Regional Health Agency (ARS), has provided specific training on the multidisciplinary management of PD for healthcare professionals in EHPADs in five departments of the Auvergne Rhône-Alpes (AURA) region-Isère, Savoie, Haute-Savoie, Drôme, and Ardèche. The hypothesis is that this theoretical training program improves staff knowledge on PD-related topics, which should lead to optimized practices and a clinically significant improvement in the quality of life (primary outcome) for people with PD residing in EHPADs.

The impact of training on professionals' knowledge will be assessed in a prior study (PARK-EHPAD PRO), an RNIPH-type study that began in October 2024. PARK-EHPAD PRO will evaluate the impact of training on knowledge, competence, and comfort in working with people with Parkinson's among healthcare professionals in EHPADs receiving the training. This study will strengthen the results of the observational PARK-EHPAD study, which focuses on the relationship between healthcare professionals' training and the quality of life of PD residents.

Among various secondary hypotheses, it is also predicted that this theoretical training program will improve not only knowledge but also the sense of competence (secondary outcome) of healthcare professionals, which should lead to an improvement in the quality of life at work (QVT) for these residents (secondary outcomes).

The results of the PARK-EHPAD study could have significant clinical implications for both the care pathway of people with PD and public health policy. For people with PD, better training for healthcare professionals in EHPADs, leading to optimized care practices, will improve comfort and the management of disability at advanced stages of the disease. This benefit could extend to residents, caregivers, and their wider circle.

Demonstrating a link between professional training and residents' quality of life in EHPADs would provide a strong argument for advocating the nationwide expansion of specific training programs to other CEPs. This would help optimize the healthcare journey for elderly individuals with PD (disability management) and improve the quality of life for healthcare professionals in EHPADs. Indeed, improving professionals' sense of competence, better disability management for residents, and improved satisfaction for residents and their families should lead to better quality of life at work for EHPAD staff. This perspective is essential in light of societal public health challenges related to the recruitment and retention of healthcare professionals in such institutions.
