Welcome to the CHIIP Study!
ommunicating Health Information and Improving Coordination with Primary Care

What is the CHIIP Study?

The CHIIP Study will recruit participants from a group of childhood cancer survivors who are enrolled in the Long-Term Follow-Up (LTFU) Study being conducted by St. Jude Children’s Research Hospital. The CHIIP Study is for LTFU Study participants who may be more likely to experience heart problems because of their cancer treatment. We want to figure out how common high blood pressure, high blood cholesterol, and high blood sugar are among LTFU Study participants.

This study is being done by the LTFU Study team at St. Jude Children’s Research Hospital and researchers from Fred Hutchinson Cancer Research Center in Seattle. It is being funded by the US National Cancer Institute (NCI).

What will be asked of CHIIP Study Participants?

  • Participants will be asked to complete a 20 minute questionnaire. There will be questions about medical history, current health, mood, lifestyle, and healthcare access.
  • We will schedule an examiner to come to the participant’s home, or another location of choice, to test for common conditions that affect heart health. The examiner will measure blood pressure, height, weight, and waist circumference, and draw blood to look for high cholesterol and high blood sugar (diabetes). Participants will receive a copy of the test results at no cost.

  • Participants with a higher than normal test result will then be randomly assigned to one of two groups. This will help us figure out how to best work with primary care providers to deal with high test results. One year later, participants in both groups will be asked to complete a second questionnaire (no more than 15 minutes) and a second in-person visit. Everyone will also have the opportunity to have a phone or web video counseling session with a study healthcare provider to review their test results, past cancer treatment history, and discuss ways to improve heart health. 

These visits and tests performed for the CHIIP Study will be free of charge. Participants and their primary doctors will receive copies of the results. Participants will also receive honoraria for participating.

What’s in it for Study Participants?
Participants will have some basic health measurements done for free, including height, weight, blood pressure, and blood levels of cholesterol and sugar. The participant and their primary care provider will receive a copy of all these test results. We hope the information we gather will provide future benefits for other people who were treated for cancer as children.
