ABSTRACT
OBJECTIVE: The effectiveness of negative pressure wound therapy (NPWT) in the prevention of postoperative surgical wound dehiscence (SWD) is the subject of much debate and remains to be determined. This study will identify individuals at risk of postoperative SWD and trial the use of NPWT as a prophylactic measure against the occurrence of SWD, compared with a non-NPWT standard surgical dressing (SSD). METHOD: A prospective multicentre randomised controlled trial comparing NPWT dressing against standard surgical dressings (SSD) will be conducted. An intention-to-treat (ITT) approach will be used for the trial. AIMS: The primary outcome is the prevention of postoperative SWD up to and including day 30 postoperative. Secondary outcomes are: prevention of surgical site infection (SSI) and economic analysis of treatment groups. CONCLUSION: This study will determine the effectiveness of NPWT in the prevention of postoperative abdominal SWD in a predefined level of risk population. This level 1 study will provide further data for abdominal SWD risk classification, which is anticipated to inform preventive postoperative management. The study design uses a prospective real-world scenario in order to identify clinically significant differences between the intervention and control groups. TRIAL REGISTRATION: This trial was prospectively registered on 10 December 2012 with Australian and New Zealand Clinical Trials Network (ANZCTR): 12612001275853.

OBJECTIVE: Surgical wound dehiscence (SWD) increases the length of hospital stay and impacts on patient wellbeing and health-care costs. Globally, the health-care costs associated with SWD are poorly reported and those reported are frequently associated with surgical site infection (SSI), rather than dehiscence of non-microbial cause. This retrospective study describes and reports on the costs and time to healing associated with a number of surgical patients who were referred to a community nursing service for treatment of an SWD following discharge from a metropolitan hospital, in Perth, Western Australia. METHOD: Descriptive statistical analysis was carried out to describe the patient, wound and treatment characteristics. A costing analysis was conducted to investigate the cost of healing these wounds. RESULTS: Among the 70 patients referred with a SWD, 55% were treated for an infected wound dehiscence which was a significant factor (p=0.001). Overall, the cost of treating the 70 patients with a SWD in a community nursing service was in excess of $56,000 Australian dollars (AUD) (£28,705) and did not include organisational overheads or travel costs for nurse visits. The management of infection contributed to 67% of the overall cost. CONCLUSION: SWD remains an unquantified aspect of wound care from a prevalence and fiscal point of view. Further work needs to be done in the identification of SWD and which patients may be 'at risk'. DECLARATION OF INTEREST: The authors declare they have no competing interests.
