^{1}: Pooled mean calculated as a combined prevalence rate over all units with 95% CI. ^{2}: Range within the individual units. ^{3}: Levels for study quality: Good (= 6 and 7 points), fair (= 3  5 points), poor (= 1 and 2 points). Numbers belong to the questions as illustrated in Table 1. ^{4}: Participants who were able to give informed consent or informed consent were given by their relatives. Abbreviations: CI, Confidence intervals; N, no; NH(E), Nursing home for the elderly; RC, Rehabilitation centre; Y, Yes; NA, No Answer; ?, unclear or missing information.
