In North America, the fiscal estimate considerable, with an estimated 234.2 of SSI is reportedly USD10bn annually in direct T million major surgical procedures carried and indirect medical costs (Urban, 2006). The out every year across the globe (Weiser et al, estimated costs attributable to SSI in Europe 2008). In Australia during 2010-11, 2.4 million range from EUR1.47bn to EUR19.1bn (Leaper et admissions involved a surgical procedure al, 2004). In Australia, estimated costs associated (Australian Institute of Health and Welfare, with SSI are AUD268 mn per year (Mclaws et 2012). Wound healing by primary intention al, 1988; Mclaws andTaylor, 2003) as reported following surgery is assisted by the use of in the acute care setting. The cost of SWD sutures, staples, glue, adhesive tape wound not only impacts the acute care setting; the dressings or negative pressure wound therapy burden is also borne by district and community (NPWT), and healing commences within hours nursing settings. Recent studies have yielded of closure (Rodero and Khosrotehrani, 2010). data regarding the cost of managing SWD Authors: Failure of the wound to heal may be due to (Tanner et al, 2009; Sandy-Hodgetts et al, Kylie Sandy-Hodgetts, Karen Ousey, Elizabeth Howse a number of reasons: patient-related factors, 2016). Further additional costs associated with for example age, cardiovascular disease delays in healing and reduced quality of life for (Webster et al, 2003; van Ramshorst G et al, the patient, family, and the wider community 2010), mechanical reasons of suture breakage may be difficult to ascertain from a financial or knots slipping (Baronski and Ayello, 2012), point of view. More importantly, the use of an infection or dehiscence (Riou et al, 1992; optimal therapy to improve wound healing Ridderstolpe et al, 2001; Webster et al, 2003; outcomes following surgery and prevent wound van Ramshorst G et al, 2010), radiotherapy complications remains to be determined. or chemotherapy (Spiliotis et al, 2009). Surgical wound dehiscence (SWD) is defined Identify risk factors: Patients may be more as the rupturing of opposed or sutured margins 1 at risk of wound dehiscence if they are following a surgical procedure (Mosby, 2009). over 65 years old, have signs of systemic and Dehiscence can occur up to and including local wound infection, are obese, or have had day 30 postoperatively, with some reports a previous surgery in the same anatomical of dehiscence occurring between day 7 and region (Australian Wound Management 9, and day 13 (Spiliotis et al, 2009).
