Data analysis: The investigators will first describe participants' baseline characteristics in each group and compare among groups. To evaluate short-term effect, Groups A and C will be compared on T2 scores with an analysis of covariance (ANCOVA) adjusted for T1 scores [16]. To document mid-term effects, a before/after analysis of variance will be used to study the evolution of continuous variables collected 3 times [17]. Sub-analyses by gender will be performed. Health system costs in intervention and control groups will be evaluated by using amounts paid to providers based on provincial fee schedules and cost-weighted utilization of institutions including hospitals and long-term care. Utilization records obtained from HA data will be multiplied by applicable cost weights (e.g. CIHI Resource Intensity Weights - RIWs) and using CIHI costs per weighted case [18] The methods employed will model the individual patient-level costs incurred in the health system, using methods developed for costing using administrative data[19]. Incremental resources in the intervention group will be identified and costed using applicable time/resource inputs and relevant wage rates following guidelines for economic evaluation in health interventions [20].
