Chronic wounds are often complex, recalcitrant to healing, and may persist for months or years due to underlying disease processes or complications. According to findings from control populations in randomized controlled trials (RCTs), a wound that is not 30% smaller by week 4 will usually not heal by week 12.1,2 The exact mechanisms that contribute to poor wound healing remain elusive but likely involve an interplay of systemic and local factors. The wound bed preparation (WBP) model was proposed by Sibbald et al.3,4,5 to systematically manage chronic wounds and optimize achievable patient outcomes. (Fig. 13.1)
