A patient-reported outcome (PRO) is a "measurement of any aspect of a patient's health that comes directly from the patient without interpretation of the patient's responses by a physician or anyone else."

/ISOQOL Dictionary of Quality of Life and Health Outcomes Measurement/


A chronic condition impacts all areas of a patient’s life. The core aim of treatment is to improve the patient’s quality of life. Only patients themselves can judge their own needs and impairments. With PROMs, patients provide their perspective without the interpretation of a clinician. This makes them crucial for the therapy planning and evaluation. Focusing on patient preferences and measuring patient-reported benefit can thus improve treatment success.


Our research group has developed widely used PROMs such as the Patient Benefit Index, the Wound-QOL, and the NAPPA. The tools are used in randomised controlled trials (RCTs), non-interventional studies and in clinical practice. They have been translated into numerous languages and were validated for different diseases and conditions.






The Patient Benefit Index (PBI) measures patient’s treatment needs and benefits. Numerous condition-specific versions are available.
