Erratum: Prevalence and Severity of Dementia in Nursing Home Residents

<b><i>Background/Aims:</i></b> The aim of this study was to compare the presence and severity of dementia in two large cross-sectional samples of nursing home residents from 2004/2005 and 2010/2011. <b><i>Methods:</i></b> Demographic information as well as data on the type of nursing home unit, length of stay before assessment, physical health, regularly used prescribed drugs and Clinical Dementia Rating scale scores were used in the analyses. Logistic and linear regression models for hierarchical data were estimated. <b><i>Results:</i></b> The odds of the occurrence and of a greater severity of dementia were higher in 2010/2011 than in 2004/2005. Independent of the time of study, married men had more severe dementia than single men, and single women had more severe dementia than single men. <b><i>Conclusion:</i></b> The findings may reflect the increase in the need for more nursing home beds designed for people with dementia between 2004/2005 and 2010/2011.
