In 1988 the Alberta government introduced a new resident classification system to measure the nursing care requirements of long-term care facility residents, and to provide case-mix information for a new funding system. This article describes the conceptual and methodological development of the system. Specific steps in the development process were to (1) define key care domains reflecting the major types of assistance required by long-term care residents; (2) identify indicators of care requirements within each care domain; (3) develop criteria for determining which items to include in the final version of the Resident Classification Form; (4) develop decision rules for combining scores on individual items in order to group residents into categories; and (5) test the psychometric properties of the classification system. The classification system has seven categories ordered from low to high in terms of nursing care requirements and a measure of nursing resource use.

In 1988 the Alberta government introduced a new resident classification system to measure the care requirements of residents in the province's long-term care facilities, and to provide case-mix information for a new funding system. This paper presents the results of the first province-wide classification process, including data for both nursing homes and auxiliary hospitals on the distribution of residents by classification indicators and categories. Data on facility case-mix indices are also presented. The results show that throughout the nursing home and auxiliary hospital system there was substantial heterogeneity in resident care requirements. Comparing across facility type, there were fewer differences between nursing homes and auxiliary hospitals in the distribution of residents on behavioural indicators than there were on indicators of physical care requirements. The paper concludes by discussing policy and planning implications of the 1988 results and the classification system more generally.

There is limited research addressing both resident and staff perceptions regarding the autonomy of institutionalized elderly residents, particularly in relation to their daily activities. This study determined residents' and their caregivers' perceptions of residents' latitude of choice regarding daily living activities. The study was conducted in two intermediate care facilities within Vancouver B.C. Study questionnaires were provided to 45 intermediate care residents and 45 nurses. Through three non-parametric statistical techniques, significant differences were found to exist between residents' and staff's perceptions. The study findings indicated that residents' extent of choice over daily activities of importance to them may not be realized to a greater extent if the staff do not attach a similar degree of importance to a particular activity. This study also indicates that, with some activities, staff do not perceive residents associating little or no choice with activities of particular importance to them.

The free radical theory of aging is critically discussed. This review deals with the biological effects of free radicals during the aging process, the relationship between aging and diseases and how they both may be affected by free radicals, and the effects of free radicals on the human lifespan. The paper emphasizes aspects which require additional investigation.

Using data from the Ontario Longitudinal Study of Aging (LSA) and data for aluminum and fluoride water concentration in areas where the LSA subjects resided, a preliminary analysis suggests that persons who show no indications of impaired mental functioning are more likely to have resided in areas where the aluminum concentrations (in drinking water) are relatively low and where fluoride concentrations (in drinking water) are relatively high. The difficulties in analyses of this type include the likelihood that many persons who are affected by impaired mental functioning do not respond to surveys, the identification of impaired mental functioning, and obtaining good exposure estimates of fluoride and aluminum drinking water concentrations.

This study descriptively compares two older Canadian seasonal migrant populations in Florida: anglophones and francophones. It is based on two surveys, an anglophone survey conducted in 1986 and a non-probability survey of francophones in 1988. This exploratory study suggests that there may be little variation in the demographic profiles, migration experience and behaviour, living arrangements and social networks between the two types of seasonal migrants. The differences that do emerge, however, are interesting. There were strikingly different settlement patterns in Florida, and the francophones were more youthful and had larger families, contributing to larger social support networks.
