Patient-reported outcome

Patient-reported outcome (PRO) is a health outcome directly reported by the patient who experienced it. It stands in contrast to outcomes reported by someone else, such as a physician-reported outcome, a nurse-reported outcome, or a caregiver-reported outcome. PROs are collected through self-report questionnaires.

Definition

The Food and Drug Administration (FDA) defines a patient-reported outcome as "any report of the status of a patient’s health condition that comes directly from the patient, without interpretation of the patient’s response by a clinician or anyone else." This can include reports of symptoms, functional status, or quality of life, among other things.

Use in clinical trials

PROs are often used in clinical trials to assess the efficacy of a treatment from the patient's perspective. They can provide valuable information about the impact of a treatment on a patient's daily life, functional status, and overall quality of life. This information can be used to inform decision-making about treatment options.

Types of patient-reported outcomes

There are several types of patient-reported outcomes, including:

• Patient-reported outcome measures (PROMs): These are measures of a patient's health status or health-related quality of life that are directly reported by the patient. They can be used to assess the impact of a disease or treatment on a patient's daily life and well-being.
• Patient-reported experience measures (PREMs): These are measures of a patient's experiences with healthcare, such as the quality of care received or the level of satisfaction with care. They can be used to assess the quality of healthcare services from the patient's perspective.
• Patient-reported behavior measures (PRBMs): These are measures of a patient's behaviors related to health, such as adherence to medication or engagement in physical activity. They can be used to assess the effectiveness of interventions aimed at changing health behaviors.
