Treatment Study of Negative Pressure Wound Therapy for Diabetic Foot Wounds

On behalf of a consortium of 19 health insurance companies the Institute for Research in Operative Medicine as part of the University of Witten / Herdecke gGmbH is planning and conducting a clinical study evaluating the efficacy and effectiveness of negative pressure wound therapy in the treatment of wound healing disorders of the foot, which are caused by diabetes mellitus. This german multicenter study is due to evaluate whether the negative pressure wound therapy or the control therapy (standard wound therapy following the guidelines) is superior. Patients will be randomly assigned to the two study arms. Both patients and the treatment staff know about the specific allocation to the negative pressure wound therapy or standard wound therapy arm. A photo documentation and a computer-based evaluation of the wound images will be performed. This is done centrally by independent examiners, who don't know neither the patient nor the treatment assignment. It is believed that the application of the negative pressure wound therapy systems compared to standard therapy of diabetic foot wounds will lead more frequent and more rapid to the achievement of complete wound closure and that the use of negative pressure wound therapy is an effective and safe therapy option for the treatment of diabetic foot wounds in inpatient and outpatient care. Patient´s to be included into the study should have either a chronic diabetic foot wound existing longer than 4 weeks whereas dead tissue components must be completely removed by the doctor or a wound after amputation of foot parts. The study treatment may have already started in the hospital if applicable. The further wound treatment will be mainly performed within outpatient care. Study Participants will return to the study centre for regular study visits or even for wound treatment. The comparison of the outcomes of both study arms will give valuable information about the efficacy of negative pressure wound therapy in inpatient a
