“…In nursing home residents, prevalence rates between 40% and 80% were found (Ferrell, 2004; Hewitt and Foley, 1996; Horgas and Dunn, 2001; Landi et al, 2001; Weiner and Rudy, 2002; Jones et al, 2005; Clark et al, 2006; Sawyer et al, 2007). Similar prevalence rates have been reported in community‐dwelling elderly (25–84%) (Brody and Kleban, 1983; Crook et al, 1984; Ferrell, 1991; Ferrell and Ferrell, 1991; Mobily et al, 1994; Brochet et al, 1998; Landi et al, 2001; Thomas et al, 2004; Clark et al, 2006; Miro et al, 2007) and elderly living in European residential homes (30–73%) (Brattberg et al, 1996; Cowan et al, 2003; Lövheim et al, 2006). For Dutch nursing homes, a pain prevalence of 68% was found in two independent studies (Smalbrugge et al, 2007; Boerlage et al, 2007).…”
