About PROBE
Patient Reported Outcomes, Burdens and Experiences (PROBE) transforms the experiences of people living with bleeding disorders into meaningful evidence for research, care and advocacy.
Patient experience at scale
A growing international evidence base built through patient participation, research and collaboration.

Evidence built around lived experience
PROBE is an international patient-reported outcomes research initiative designed to understand how bleeding disorders affect health, treatment, function and everyday life.
It collects standardized information directly from participants and transforms those experiences into data that can be analyzed across populations, countries and over time.
By placing patient experience alongside clinical evidence, PROBE helps make outcomes that matter to patients visible in research, healthcare discussions and evidence-based advocacy.
Turning lived experience into meaningful evidence
PROBE provides a standardized way to capture patient experience, understand patterns and support the use of patient-reported evidence.
Capture
Collect patient-reported information about health, treatment, pain, function, quality of life and everyday experience.
Understand
Transform standardized patient-reported information into evidence that can be analyzed, compared and interpreted.
Advocate
Use evidence to support patient organizations, researchers and decision-makers seeking better outcomes and access to care.
More than a clinical snapshot
PROBE captures multiple dimensions of health and everyday life to provide a broader picture of patient experience.
01
Health & Treatment
Bleeding disorder characteristics, treatment history, bleeding experiences and other health conditions.

Pain
Acute and chronic pain, pain occurrence, interference with activities and use of pain medication.
03
Daily Living
How health affects everyday activities, independence, participation and ability to perform daily tasks.
04

How PROBE is used
Patient-reported evidence can support different parts of the bleeding disorders community.
Make experience visible
Participation allows individual experiences to become part of a larger evidence base describing life with a bleeding disorder.
Strengthen advocacy
Patient-reported evidence can help organizations understand community priorities and support evidence-based advocacy.
Support research
PROBE can complement clinical information with standardized patient-reported outcomes in studies, registries and collaborative research.
Interactive evidence at your fingertips
PROBE transforms patient-reported data into interactive visualizations that support research, interpretation and advocacy.
Explore patterns across geography, diagnosis, treatment, pain, activities of daily living, quality of life and other dimensions of the PROBE dataset.
Simplify. Analyze. Advocate.
Turn standardized patient-reported information into evidence that can be explored, interpreted and communicated.
Frequently asked questions
Quick answers about PROBE, patient-reported outcomes and research use.
What does PROBE stand for?
PROBE stands for Patient Reported Outcomes, Burdens and Experiences. It uses information reported directly by participants to understand health, quality of life and experiences that matter to people living with bleeding disorders.
What is the main goal of PROBE?
PROBE generates standardized patient-reported evidence that can help patients, patient organizations, researchers and other stakeholders understand outcomes, treatment burden and experiences of care.
What information does PROBE collect?
PROBE collects information related to health and treatment, bleeding, pain, activities of daily living, mobility, joints, education, employment and quality of life. The questionnaire also incorporates EQ-5D-5L.
Why does PROBE include comparison participants?
Comparison information from people without bleeding disorders can help researchers understand how health and daily-life outcomes differ between people living with bleeding disorders and others within similar populations.
Can PROBE be used in research studies?
Yes. PROBE can support patient-centered outcome collection within research studies and complement clinical information with standardized patient-reported evidence.
Independent, investigator-led research
PROBE is an independent investigator-led research project developed to establish reliable and reproducible methods for collecting patient-reported outcomes, burdens and experiences.
Its research program supports comparisons across populations and countries, longitudinal analysis, digital data collection, registry integration and expansion into broader bleeding-disorder populations.
