Rapid decrease in length of stay in institutional care for older people in Sweden between 2006 and 2012: results from a population-based study.

Abstract

There is limited knowledge about older people's length of stay (time until death) in institutional care and how it has changed over time. The aim of this study was to analyse changes in the length of stay for older people in institutional care between 2006 and 2012. All persons 65+ living in Kungsholmen (an urban area of Stockholm), who moved to an institution between 2006 and 2012, were included (N=1103). The data source was the care system part of a longitudinal database, the Swedish National Study on Aging and Care. The average length of stay was analysed using Laplace regression for the 10th to the 50th percentile for the years 2006-2012. The regressions showed that in 2006, it took an average of 764days before 50% of those who had moved into institutional care had died. The corresponding figure for 2012 was 595days, which amounts to a 22.1% decrease over the period studied (P=0.078). For the lower percentiles, the decrease was even more rapid, for example for the 30th percentile, the length of stay reduced from 335days in 2006 to 119days in 2012, a decrease of 64.3% (P<0.001). The most rapid increase was found in the proportion that moved to an institution and died within a short time period. In 2006, the first 10% had on average died after 85days, in 2012 after only 8days; a decrease in the length of stay of 90.5% (P=0.002). In general, there was a significant decrease in the length of stay in institutional care between 2006 and 2012. The most dramatic change over the period studied was an increase in the proportion of people who moved into an institution and died shortly afterwards.
