- Brief Summary
Post-operative wound issues in abdominal surgery have a significant impact on patient outcomes. This study is taking place to investigate if Negative Pressure Wound Therapy (NPWT) dressings reduces Surgical Site Infections, post surgical complications and improves scar appearance compared to standard dressings.
- Detailed Description
NPWT dressings are designed to remove and absorb any fluid leaking from the wound. This might reduce surgical site infections, improve wound healing and improve scar appearance compared to using standard dressings.
Data is limited in the application of NPWT dressings to laparotomy incisions in the acute and elective care surgery setting. Surgical site infections can complicate a patient's post-operative course significantly, often necessitating a longer length of stay, antibiotic therapy, intervention for wound collections and impair patient mobility and overall recovery.
In addition to this, laparotomy wound complications can possibly delay adjuvant therapy and also increases healthcare costs both as an inpatient and in the community. Despite significant measures to reduce such complications in the form of wound care bundles, changing of gloves prior to wound closure etc., surgical site complications continue to represent a huge healthcare burden.
The Investigators are conducting this study to determine whether NPWT dressings reduce surgical site infections, improve wound healing and scar appearance. This study will also involve a cost-based analysis and seek information from patients on their quality of life. Results from this study will provide evidence on whether these dressings should be used as standard of care for management of surgical laparotomy wounds.

Group Intervention Description Standard Wound dressing Standard wound dressing After the skin is closed, the wound is covered using sterile standard gauze dressing. Negative Pressure Wound Therapy Negative Pressure Wound Therapy The wound is dressed using negative pressure wound therapy.
- Primary Outcome Measures
Name Time Method Rate of Surgical Site Infection (SSI) 6 months following surgery To compare the rate of surgical site infections within 6 months of the surgical procedure, using Negative Pressure Wound Therapy compared to standard dressings. SSIs will be classified according to Centre for Disease Control (CDC) criteria.
- Secondary Outcome Measures
Name Time Method Health Economics evaluation of resource use and cost effectiveness using Negative Pressure Wound Therapy dressings 6 months Investigating resource use and cost effectiveness of single-use, prophylactic negative pressure wound therapy versus standard dressings for midline laparotomy wounds based on length of hospital stay and costs of dressings
Scar assessment - using the Patient and Observer Scar Assessment Scale (POSAS) 6 months following surgery The POSAS is made up of two scales: the patient scale and the observer scale; each of the six components is scored numerically on a scale of 1 to 10. The component scores are then added together; the worst scar would receive a score of 60, while the best scar would receive a score of 6
Healthcare incremental cost- utility ratio 6 months The incremental cost-effectiveness ratio at 6 months for NPWT vesus standard dressings for patients undergoing laparotomy.The effectiveness will be expressed as quality adjusted life years (QALYs) in a cost-utility analysis. QALYs are a composite measure of outcomes where utilities for health states (on 0-1 scale, where 0 corresponds to death and 1 to full health) act as qualitative weights to combine quantity and quality of life. The number of QALYs in each group will be assessed with the EuroQol 5 Dimensions questionnaire (EQ5D). The EQ-5D measures health status in terms of mobility, self-care, usual activities, pain/discomfort and anxiety/depression
Health-related quality of life with the EuroQol-5 dimensions five level index questionnaire (EQ-5D-5L) 6 months following surgery The questionnaire covers five dimensions of health: mobility, self-care, usual activities, pain or discomfort, and anxiety or depression. Each dimension has 5 levels: no problems (1), slight problems (2), moderate problems (3), severe problems (4) and extreme problems (5). The patient is asked to indicate his/her health state by ticking the box next to the most appropriate statement in each of the five dimensions. The raw scores are also converted to an EQ-5D index value using a scoring algorithm (British tariff) ranging from -0.594 (worst perceived health state) to 1.00 (best perceived health state)
Health-related out-of- Pocket Costs assessed using the Costs for Patients Questionnaire (CoPaQ) 6 months The CoPaQ measures patient and caregivers out-of-pocket expenses (direct and indirect) associated with a health condition
Healthcare cost-effectiveness ratio at 6 months 6 months Assessment of the cost-effectiveness ratio at 6 months between NPWT dressings compared to standard dressings. The criteria of effectiveness used will be; Length of hospital stay, requirement for return to theatre, requirement for critical care and number of dressings used
