Health-Related Quality of Life (HRQL)
Health-Related Quality of Life (HRQL) is a measure of how a person's physical, mental, and social well-being is affected by their health condition or treatment, typically captured through validated patient-reported surveys in research and outcomes studies.
What is Health-Related Quality of Life (HRQL)?
Health-Related Quality of Life (HRQL) is a measure of how a person's health condition or its treatment affects their physical, mental, and social well-being. Rather than focusing only on clinical markers, it captures the patient's own experience of living with a condition.
It is usually assessed through validated patient-reported questionnaires that ask about functioning, symptoms, and emotional state, producing data that can be tracked over time.
Why does HRQL matter in research?
In clinical trials and outcomes studies, HRQL provides evidence of benefit that lab values and survival rates alone cannot show, such as whether a treatment helps people feel better and do more. Regulators and payers increasingly value this patient-centered perspective.
Because it reflects what matters to patients directly, HRQL data strengthen the case for a therapy's real-world value and feed into broader evaluations of effectiveness. It has become a standard endpoint in many studies that assess treatment impact.
