Patient-reported outcomes-the role of the patient's subjective perspective for research and clinical care

Because only patients can adequately assess symptoms, disability, and quality of life, concordance between a patient's and physician's assessment is often low. Accordingly, patient-reported outcomes (PROs) are increasingly used in research and routine clinical care. In daily practice, PROs are not only applied to measure the patient's perceived outcome of medical treatments, but also to assess their health status before intervention starts. Typically, several patient-reported outcome measures (PROMs), which are reliable and valid, are available for the assessment of the most important PROMs. In daily clinical practice, the integration of PROs can be useful for clinical assessment and treatment planning or for quality management. Currently, the most promising application is routine patient monitoring using digital PROMs (ePROMs). Systematic reviews have revealed that the routine use of PROMs in daily clinical care is associated with, among others, improved physician-patient communication, higher patient satisfaction, reduced symptom burden, higher quality of life, and improved survival. This effect is especially strong if health care professionals continuously receive the results of the PRO monitoring. Patients are usually inclined to disclose their health status, and the positive effects of routine patient monitoring are widely recognized. However, several barriers to using PROs and PROMs still exist.
