Benefit evaluation in the therapy of chronic wounds from the patients' perspective--development and validation of a new method.

Assessing therapeutic benefit of any drug and medical device is essential in registration and cost reimbursement decisions in Germany and in many nations. In this study, a method for the assessment of patient-relevant benefits in wound therapy was developed and validated. A total of 83 items on treatment benefit from the patients' perspective were collected in an open survey, including n = 50 patients with chronic wounds.
