Conscious of problems related to coordination of services for the elderly on its territory, the working group on health and social services of the Bois-Francs in the Mauricie and Centre-du-Québec regions implemented in February 1997, after two years of planning, a new coordination model of services for the frail elderly. This model is innovative because it combines the unique entry, case management, individualized services plan as well as the presence of three levels of concertation : strategic, tactical and clinical. The model also has the characteristic of offering comprehensive services to the elderly. This article describes the major results of an assessment of the implementation and process of this model. This assessment aimed at documenting the activities and functions of the coordination mecanism of services in order to see to what extent the model implemented and its functionning is close or not to the one proposed and this, in a perspective of bringing the necessary adjustments. The major results on clientele reached, various functions of a team of case managers and organization of work are discussed in the light of other studies on coordination of services for frail older people. Suggestions regarding these results and those pertaining to efficiency and cost in another study are made in order to improve the efficiency of the model. Many components of this new model could be applied to other clientele.
