Negative pressure wound therapy for surgical wounds healing by secondary intention is not cost-effective
Clinical Scorecard: Cost-Effectiveness Analysis of Negative Pressure Wound Therapy for Surgical Wounds Healing by Secondary Intention Reveals Limitations
At a Glance
Category Detail
Condition Surgical wounds healing by secondary intention (SWHSI) Key Mechanisms Negative pressure wound therapy (NPWT) applies subatmospheric pressure to remove exudate, reduce oedema, promote perfusion, cellular proliferation, and granulation tissue formation to aid wound healing Target Population Patients with surgical wounds healing by secondary intention Care Setting UK National Health Service (NHS) healthcare system
Key Highlights
NPWT is associated with higher costs and marginally higher quality-adjusted life-years (QALYs) compared to standard dressings for SWHSI. The probability of NPWT being cost-effective is less than 30%, with considerable uncertainty driven by pooled relative effect estimates. No clear evidence from RCTs or economic models supports NPWT as a cost-effective alternative to standard dressings for SWHSI. Guideline-Based Recommendations
Diagnosis
Identify wounds healing by secondary intention post-surgery, characterized by open wounds healing from the bottom up via granulation tissue. Management
Standard dressings remain the primary treatment for SWHSI given current evidence. NPWT use should be considered cautiously due to lack of demonstrated clinical or cost-effectiveness. Monitoring & Follow-up
Monitor wound healing progression from unhealed to healed states over time. Track complications such as infection, hospital readmission, and need for further surgery. Risks
NPWT incurs higher intervention costs without clear clinical benefit. Potential for increased healthcare resource utilization without improved outcomes. Patient & Prescribing Data
Patients with surgical wounds healing by secondary intention in the UK healthcare setting
NPWT does not significantly reduce time to wound healing or complications compared to standard dressings and is unlikely to be cost-effective.
Clinical Best Practices
Use standard dressings as first-line treatment for SWHSI. Reserve NPWT for selected cases where clinical judgment supports its use, acknowledging limited evidence. Incorporate comprehensive economic evaluations alongside clinical trials to inform treatment decisions. Consider patient quality of life and healthcare costs when selecting wound management strategies. References
