Review Question - QID 214746

A 48-year-old woman presents to a wound center to follow up regarding a surgical site wound that she has on her abdomen. The patient underwent an open abdominal procedure 3 months prior, and a superficial dehiscence of the inferior aspect of the incision was noticed at her first postoperative visit. The provider evaluating this patient is deciding whether to start the patient on negative pressure wound therapy, which he has not previously used on any patients. He is considering changing his standard of practice for chronic wounds. Which of the following types of evidence in favor of negative pressure wound therapy for chronic wounds would best support this change in practice?
