Age, costs of acute and long-term care and proximity to death: evidence for 1987-88 and 1994-95 in British Columbia.

BACKGROUND

the consequences of ageing populations for health care costs have become a concern for governments and health care funders in most countries. However, there is increasing evidence that costs are more closely related to proximity to death than to age. This means that projections using age-specific costs will exaggerate the impact of ageing. Previous studies of the relationship of age, proximity to death and costs have been restricted to acute medical care.

OBJECTIVE

to assess the effects of age and proximity to death on costs of both acute medical care and nursing and social care, and to assess if this relationship was stable in a time of rapid change in health care expenditure.

DESIGN AND METHODS

we compared all decedents in the chosen age categories for the years 1987-88 and 1994-95 with all survivors in the same age groups. We measured use of health and social care for each individual using the British Columbia linked data, and costs of care assessed by multiplying the number of services by the unit cost of each service.

SETTING

the Province of British Columbia.

SUBJECTS

all decedents in 1987-88 and 1994-95 in British Columbia in the chosen age groups, and all survivors in the same age groups.

RESULTS

costs of acute care rise with age, but the proximity to death is a more important factor in determining costs. The additional costs of dying fall with age. In contrast, costs of nursing and social care rise with age, but additional costs for those who are dying increase with age. Similar patterns were found for the two cohorts.

CONCLUSIONS

age is less important than proximity to death as a predictor of costs. However, the pattern of social and nursing care costs is different from that for acute medical care. In planning services it is important to take into account the relatively larger impact of ageing on social and nursing care than on acute care.
