ClinConnect Summary

This clinical trial is studying a new type of dressing called Negative Pressure Wound Therapy (NPWT) to see how well it works in treating both chronic and acute wounds. Chronic wounds are those that haven’t healed properly after standard care for at least 30 days, while acute wounds can be from injuries or surgeries. The goal is to find out if this new dressing can help these wounds heal better and faster.

To participate, individuals must be at least 18 years old, currently hospitalized, and able to attend follow-up visits after being discharged. They should have a suitable wound that can be treated with the NPWT dressing. However, some people may not be eligible, such as those with certain medical conditions or infections. If you join the study, you will receive the new dressing and will be monitored to see how your wound responds. This trial is now recruiting participants, and the information gathered will help improve wound care for future patients.

• • Subject participation in the treatment period of another clinical trial within thirty (30) days of baseline visit or during the study.
