Key requirements
Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.
- Ages 2 to 25 years
- All sexes
- No healthy volunteers
- Child, Adult
Study population: The study population will include pediatric and young adult patients aged 2-25 years with a confirmed diagnosis of Hereditary Hemorrhagic Telangiectasia receiving care at Cincinnati Children's Hospital Medical Center. Eligible participants will be identified through the electronic medical record based on diagnostic criteria and clinic records. Both caregiver proxy respondents (for children aged 2-17 years) and patient self-report respondents (for individuals aged 8-25 years) will be included. Participants will complete validated quality-of-life questionnaires assessing health-related and disease-specific quality of life over the prior 30 days. A paired retrospective chart review will be conducted to obtain clinical variables including disease severity, procedures, imaging studies, and other healthcare utilization measures associated with HHT.
Who may be able to join
- • Patient aged 2-25 years with a confirmed (either genetic or clinical) diagnosis of definite HHT
- Parent or legal guardian willing and able to complete the caregiver survey for patients aged 2-17.
- For patients >18, willing and able to complete the patient survey.
- Receipt of care through CCHMC (at least one visit with genetic counselor or director of HHT Center)
- Ability to complete survey in English
- For self-report: patient age greater than or equal to 8 years old that assent to survey.
Who cannot join
- Patients that are older than 25 years old.
- Patients that are younger than 2 years old.
- Individuals without definite HHT diagnosis.

About this study
Official title: Health-Related Quality of Life and Clinical Utilization in Pediatric and Young Adult Patients With Hereditary Hemorrhagic Telangiectasia
This observational study evaluates health-related quality of life (HR-QoL) in pediatric and young adult patients aged 2-25 years with Hereditary Hemorrhagic Telangiectasia (HHT). Eligible participants are patients receiving care at Cincinnati Children's Hospital Medical Center and / or their caregivers. Participants will complete validated quality-of-life questionnaires assessing physical, emotional, social, and disease-specific functioning over the past 30 days. A paired retrospective chart review will assess disease severity and clinical utilization, including procedures and imaging studies. The primary objective is to describe mean QoL scores for this population. Secondary objectives include evaluating associations between QoL scores, disease severity, and clinical utilization.

What is being measured
The primary outcome is the main question the study is designed to answer.
PedsQL Total Score
Mean total health-related quality of life score measured using the Pediatric Quality of Life Inventory (PedsQL). Scores range from 0-100, with lower scores indicating worse quality of life.
Measured: 30 days
HHT-QOL
Mean score ranging from 0-16 assessing HHT-related symptom burden and functional impact. Higher scores indicate worse impairment.
Measured: past 30 days
Secondary outcomes (3)
Epistaxis Severity Score
Continuous score (0-10) measuring nosebleed severity. Higher scores indicate more severe epistaxis.
Measured: past 30 days
HHT Severity Score
Continuous score ranging 0-7 reflecting lifetime disease severity based on organ AVMs and bleeding history.
Measured: lifetime
Clinical Utilization
Number of procedures (embolization, cauterization) and imaging studies (MRI, CT, bubble echocardiography).
Measured: lifetime
