The nursing home case-mix classification system, Resource Utilization Groups Version III (RUG-III), has been tested and refined for long-term home care clients. The study sample included 804 individuals seeking home care through the Michigan Care Management Program or the Home and Community Based Waiver for the Elderly and Disabled. Clients were classified, and RUG-III models were derived using the Minimum Data Set for Home Care (MDS-HC). A refined home care model, RUG-III/HC, was developed incorporating Instrumental Activities of Daily Living (IADLs) to the nursing home RUG-III classification. The model explained 33.7 per cent of the variance of per diem cost, using cost weighted formal and informal care as the dependent variable. Resource use within groups was relatively homogeneous. The case-mix index (CMI) of weighted formal and informal care time spanned an eight-fold range. Further analysis is suggested regarding the inclusion of informal care as a cost in case-mix classification for long-term home care clients.
Le système de classification de la composition de la clientèle des maisons de soins infirmiers, Resource Utilization Groups Version III (RUG-III), a été éprouvé et raffiné pour les bénéficiaires de soins de longue durée à domicile. Lapos;échantillonnage étudié regroupe 804 personnes recevant des soins à domicile par l'entremise du Michigan Care Management Program ou du Home and Community Based Waiver for the Elderly and Disabled. On a catégorisé les clients et établi des modèles de RUG-III à partir du Minimum Data Set for Home Care (MDS-HC). On a établi un modèle raffiné de soins à domicile, RUG-III/HC, en incorporant les activités instrumentales de la vie quotidienne (AIVQ) à la classification RUG-EH des établissements de soins. Le modèle explique 33,7 pour cent de la variance des coûts quotidiens, à partir de la variable dépendante du coût pondéré des soins structurés ou non. L'utilisation des ressources à l'égard des différents groupes est relativement homogène. Le CMI (case-mix index) du temps pondéré des soins structurés ou non couvre une échelle de 8. Il faudra songer à effectuer des analyses plus poussées du coût de l'inclusion des soins non structurés à l'égard des patients recevant des soins à domicile de longue durée.
