Third Wave of the EVAL-PLH (POLYhandicap) Cohort: New Eyes

The general objective of the EVAL-PolyNE project is to improve the representativeness of the EVAL-PLH cohort by broadening participation in the John Bost Foundation, due to its geographical particularity and its private valence.

Studies on people with profound intellectual and multiple disabilities (PIMD)/Polyhandicap are rare, involve small numbers and highly heterogeneous groups, and document narrow objectives focused on targeted health problems. Although valuable, these studies provide only fragmentary knowledge of the medical, socio-economic and epidemiological determinants of the health and experience of people with PIMD/Polyhandicap and their families. Existing studies are based on retrospective or cross-sectional data. These study designs do not make it possible to identify causal links between the phenomena observed. Only cohort studies can provide a longitudinal vision, enabling us to study the dynamics of the phenomena observed (care, access to different care structures, environment in the broadest sense, state of health and experiences of these people and their families). The information made available is essential for informing healthcare decision-makers, healthcare professionals and the families of these people, and for proposing the most appropriate targeted actions.

The Eval-PLH cohort of people with PIMD/Polyhandicap was initiated in 2015, with the aim of describing prospective changes in the health characteristics of people with PIMD/Polyhandicap, clinical practices and management strategies for PIMD/Polyhandicap. It also assesses the impact of PIMD/Polyhandicap on the experiences of family carers and the institutional carers (caregivers) who support them.

The 1st wave of observation took place in 2015-2016. Nearly 900 people with PIMD/Polyhandicap, 400 family carers and 400 institutional carers were assessed thanks to the participation of six specialized follow-up care and rehabilitation centers, eight medico-social structures (MAS and IME) and one neuropediatric consultation service. Data mining has enabled us to build up an unprecedented knowledge base. This work confirmed the diversity and evolution of pathologies, the heterogeneity of medical practices and the impact on family and institutional caregivers.

The 2nd wave of observation took place in 2020-2021 and assessed 624 people PIMD/Polyhandicap (132 new cases, 492 cases present in the 1st wave), 226 family carers and 223 institutional carers in four specialized follow-up care and rehabilitation centers and eight medico-social structures. These data are currently being explored and valorized. They provide considerable scientific added value thanks to their longitudinal perspective. A more detailed understanding of the phenomena (through a qualitative approach based on interviews) complements the initial purely quantitative approach.

The present study, which concerns the 3rd evaluation wave, aims to optimize the system, particularly in terms of the representativeness of the populations studied. The extension of the system to less targeted geographical areas and to non-public structures will shed new light on the care organizations and professionals affiliated with these structures, as well as on the experiences of the people cared for (patients and families).
