What is the difference between a PRO and a PROM

Definition: Patient-Reported Outcome (PRO)

A PRO is defined as any information on the outcomes of health care obtained directly from patients without modification by clinicians or other health care professionals.

Definition: Patient-Reported Outcome Measure (PROM)

A PROM is a survey that captures a patient’s self-assessment of health including status (mental, physical), function, symptoms, and health related quality of life (HRQL). It is an important research tool used in PRO programs.
