Simplified Negative Pressure Wound Therapy: A Cost-Effective Solution for Wound Management

Area of Science:

• Wound Healing
• Biomedical Engineering
• Public Health

Background:

• Negative pressure wound therapy (NPWT) is effective for chronic wounds but costly.
• Limited accessibility of commercial NPWT hinders use in resource-constrained areas.
• Need for affordable wound management solutions in low-resource settings.

Purpose of the Study:

• To evaluate the efficacy of an indigenously developed simplified negative pressure wound dressing (SNPWD).
• To assess SNPWD's potential as a low-cost alternative for wound management in resource-limited environments.

Main Methods:

• Prospective cohort study involving 24 patients with chronic wounds.
• Application of SNPWD and documentation of wound area, treatment duration, dressing changes, and exudate.
• Comparison of pre- and post-treatment wound cultures.

Main Results:

• Mean wound surface area decreased by 27.2% after SNPWD application.
• Healthy granulation tissue developed in a mean of 16.5 days (range 8-27 days).
• Post-treatment wound cultures were sterile in 96% of cases, a significant improvement from 37.5% pre-treatment.

Conclusions:

• SNPWD is a safe, effective, and cost-efficient alternative to commercial NPWT systems.
• SNPWD demonstrates comparable clinical outcomes at a significantly lower cost.
• SNPWD has strong potential for widespread adoption in managing complex wounds, particularly in resource-limited settings.
