Specific Care and Assistance Plan for Alzheimer's Disease — PLASA  

Alzheimer's Disease Clinical Trial

Official title: Specific Care and Assistance Plan for Alzheimer's Disease: Impact Study on Disease Progression and Management Modalities

Status Completed

Clinical Trial Summary

The main objective of this work is to assess the feasibility and efficacy of a specific Care and Assistance Plan for Alzheimer's disease (PLASA). The main outcome measure selected is incapacity in carrying out the basic activities of daily living, evaluated by the ADCS-ADL scale .

The PLASA was developed by a working group appointed by the Direction Générale de la Santé as part of the government programme of action on Alzheimer's disease (October 2001, Ministère de l'Emploi et de la Solidarité).

Clinical Trial Description

It is estimated that at the present time about 50% of dependence in the elderly is related to dementias. Alzheimer's disease is the most common of these, and there are 100 000 new cases in France every year (Girard Report). Very often, once the diagnosis has been established these persons do not receive regular, codified follow-up, whereas Alzheimer's disease is a chronic disease which progresses over several years and leads to a variety of complications which must be identified and managed.

The main objective of this work is to assess the feasibility and efficacy of a specific Care and Assistance Plan for Alzheimer's disease (PLASA). The main outcome measure selected is incapacity in carrying out the basic activities of daily living, evaluated by the ADCS-ADL scale .

The PLASA was developed by a working group appointed by the Direction Générale de la Santé as part of the government programme of action on Alzheimer's disease (October 2001, Ministère de l'Emploi et de la Solidarité).

Methods The multicentre prospective study will be randomised within each centre. Study population: 1200 patients will be recruited in 20 French university hospitals and 40 general hospitals.

Inclusion criteria: Patients presenting mild to moderate Alzheimer's disease diagnosed by the NINCDS-ADRDA criteria (MMSE between 12 and 26), living at home and with an identified principal caregiver.

Randomisation and patient follow-up: After randomisation within each centre (specialised department of the university or general hospital), half of the patients will be managed according to the PLASA (group A). The other patients will receive the usual management of the centres (group B).

The PLASA includes detailed evaluation of the patient's cognitive and non-cognitive function, regular and standardised follow-up, management of complications and the setting up of assistance and support services according to common guidelines. As part of the PLASA, patients will be systematically seen in consultation every six months.

Data collection: In group A, data will be collected during six-monthly consultations for the duration of the study (T0, T6, T12, T18, T24). In group B, data will be collected during consultations at T0, T12 and T24. The coordinating centre (Toulouse) will contact every 6 months (T6, T12, T18, T24), by post or by telephone, the principal caregiver for collection of intermediate data in both groups. These data include evaluation of activities of daily living (ADCS-ADL), utilization of support and care services (RUD ), as well as subjective assessment of disease severity (ADCS-CGIC ). The patient's quality of life will also be evaluated in both groups at T0, T12 and T24.

Statistical analysis: 1200 subjects are needed to reveal a 30% decrease in incapacities in activities of daily living in the group of patients followed according to the PLASA.

Bivariate analysis will be carried out using the standard tests for this type of study (chi-squared test and Student's t test). The efficacy of the PLASA will be assessed by multivariate analysis, taking potential confounders into account.

Expected results: This project should contribute to better long-term management of patients with Alzheimer's disease and should reduce the burden on families. ;
