Connected Solution of Assistance Dedicated to Caregivers and People With Alzheimer's Disease or Related Diseases

Lili Smart Study - Connected Solution of Assistance Dedicated to Caregivers and People With Alzheimer's Disease or Related Diseases

Alzheimer's disease and related diseases (ADRD) are a major public health issue. In France, nearly 900,000 people have ADRD, which represents about 70% of dementia cases, and the expected prevalence for 2020 is 1.2 million.

Patients with ADRD have cognitive, behavioral and functional impairments that lead to progressive impairment of quality of life and autonomy. Maintaining them at home depends predominantly on their caregivers, mainly family, spouse or child. By definition, the caregiver is "the person who provides partial or total support to an elderly dependent person or a person with a disability in the vicinity of the victim for the activities of daily life".

The investment of caregivers is therefore both human and financial, representing a greater or lesser burden. This burden can significantly affect their quality of life. Indeed, studies have shown that caregivers suffer from depletion, anxiety, depression and sleep disorders resulting in a deterioration of their health, leading them to greater care consumption. They would be more prone to cardiovascular diseases and cancer.

A review of the literature from 2009 examined 66 studies evaluating the contribution of various technologies targeting demented patients and their caregivers. Of these, only 10 dealt with independence at home and the well-being of the patient and his / her caregiver. The main limitations of these studies are the small samples (ranging from 1 to 6 patients), the degree of cognitive degradation (mainly moderately severe) and the lack of standardized assessment.

Although new technologies promise powerful home-based solutions, studies evaluating their efficacy for patients with ADRD and their caregivers remain scarce and fragile at the level of evidence due to methodological biases.

Description of the intervention: Lili Smart solution consists of an application for caregivers (web / mobile), a GSM watch worn by the patient, smart sensors placed at different locations of the patient's home and a support service 24 / 24 and 7/7.

Objectives: The main objective is to evaluate the impact of the Lili Smart solution on the burden felt by caregivers of patients with ADRD at 3 months and at 6 months of follow-up.

The secondary objectives are to evaluate the impact of the Lili Smart solution at 3 months and 6 months of follow-up on:

• The anxiety of the caregiver of the patient with ADRD;
• Depression of the caregiver of the patient with ADRD;
• The quality of life of the caregiver of the patient with ADRD;
• The quality of life of the patient with ADRD,
• The level of functional autonomy of the patient with ADRD.
• The risks associated with the functional decline (falls, run aways) of the patient with ADRD.

In addition to the social impact measurement, the study aims to demonstrate the medico-economic impact of Lili smart solution as follow:

• The direct and indirect medical costs of the patient and the caregiver.

Patient and caregiver adherence to the Lili Smart solution will also be assessed as a secondary objective.

Methodology : This study is an interventional research on the human person meeting the definition 1 ° of article L1121-1 of the CSP and not relating to the products mentioned in article L. 5311-1 It is a randomized, controlled, single-blind, parallel-group, interventional, randomized, controlled trial in N = 60 patients and their primary caregiver with an observational phase (inactive device), and one interventional phase (activated device).
