RESUMO
Background: Among case mix classifications, the best for hospitalized elders is the Resource Utilization Groups (RUG) system, which allows a better location of patients, resource administration and the design of health care strategies for elderly people. Aim: To report the results of RUG-T18 classification of elderly patients admitted to an university hospital. Patients and methods: RUG-T18 classification was applied to 210 patients aged 75.2 ñ 7.2 years old, 108 male, admitted to the Clinical Hospital of the Catholic University of Chile. Results: The clinical classification of assessed patients was rehabilitation in 50.9 per cent of cases, special care in 10.5 per cent, clinically complex in 37.1 per cent and reduced physical functions in 0.5 per cent. None had behavioral alterations. There were no differences between subjects older or younger than 75 years old. Daily life activities showed that help was required for sphincter control in 46 per cent of patients, for feeding in 44 per cent and for mobilization in 64 per cent (28 per cent of patients required help from two or more people). Geriatric assessment showed that, since 1993, the proportion of elders with greater functional derangement increased from 18 to 28 per cent, and the proportion of those with mental disturbances from 4 to 12 per cent, specially among those over 75 years old. Conclusions: Most elders admitted to the hospital are classified in the superior categories of the RUG-T18 system and have severe mental and functional limitations. These patients require a multidisciplinary approach with a great emphasis in rehabilitation
