Traditional clinical data sources allow us to collect  physical, physiological, and biochemical data on patients  and treatment efficacy and safety but do not capture  all the data about the treatment or the disease. Patientreported treatment satisfaction with medication may  be obtained only from the patient.44 For this reason,  PROs such as the TSQM have become increasingly  valuable to clinical research and practice. They can  provide meaningful and reliable information on the  patient experience of treatment satisfaction, not just  with medication, but with procedures and other forms  of care, and may be used by regulators, payers, clinical  research, and clinical practice to identify the added value  of a given treatment from the patient’s perspective.
