“…Treatment of a Stage 4 ulcer averages over $124,000 per patient (Brem et al, 2010). The prevalence of PUs among nursing home (NH) admissions has been reported to be 10%-33% (Capon, Pavoni, Mastromattei, & Di Lallo, 2007; Baumgarten et al, 2004; Brandeis, Morris, Nash, & Lipsitz, 1990; Kiel, Eichorn, Intrator, Silliman, & Mor, 1994; Sternberg, Spector, Kapp, & Tucker, 1988; Zulkowski, 1998). Due to the difficulty in reliably identifying the least severe Stage 1 PUs (DeFloor & Schoonhoven, 2004), some studies exclude this stage (Baumgarten et al, 2004; Brandeis et al, 1990) or report Stage 1 results separately (Sternberg et al, 1988).…”
