Project Summary

PCORI implementation projects promote the use of findings from PCORI-funded studies in real-world healthcare and other settings. These projects build toward broad use of evidence to inform healthcare decisions.

This PCORI-funded implementation project is adapting feedback reports that provide information about the amount of radiation in different types of computed tomography, or CT, scans for use across all healthcare settings.

Each year, patients in the United States receive 90 million CT scans. CT scans provide images that can help detect injury or disease inside the body or that can guide medical procedures. However, CT scans expose patients to radiation, which can increase the risk of cancer. Lowering the amount of radiation patients receive during a CT scan can reduce unnecessary health risks.

What is the goal of this implementation project?

CT scans can help find a wide range of health problems such as fractures or cancers. But these scans also expose the patient to a certain amount of radiation, called a CT dose. A PCORI-funded research study found that CT doses varied by hospital. Hospital policies, such as who could change CT scanning procedures, were more important than other factors, such as the type of scanner, in determining why doses varied. Sharing feedback reports with hospitals about their own practices and optimal CT doses for different types of scans reduced the average radiation per scan for all patients. Patients at these hospitals were also less likely to get a CT scan with a high dose of radiation.

This project will adapt the CT radiation feedback reports for use in different healthcare settings.

What will this project do?

The project team is working with 13 health systems and hospitals. Using the feedback reports, the team is helping these organizations optimize the doses used for CT scanning. The project team is:

  • Creating an approach for categorizing the reasons for CT scans and determining the right radiation dose and image quality for each type of scan
  • Simplifying the feedback report provided to doctors to help them reduce the use of high-dose CTs
  • Adding information on CT image quality to the feedback report
  • Organizing the information to help sites respond to other patient safety efforts

During the project, the team is reviewing CT scan records from each site and providing the feedback reports. They are also developing online training for staff to help interpret the reports. The team is then sharing the feedback by posting it online and sharing it at an online course. The team is creating standards for how routine exams should be performed.

Participating staff at sites include radiologists, radiological technologists, medical physicists, doctors who perform CTs, and administrators. The team is also working with professional societies and others to encourage use of the tools.

What is the expected impact of this project?

This project will initiate use of the radiation feedback reports in different healthcare settings. The refinements to the feedback report, materials developed during the project, and the support of professional groups and others working with the project will help with further scale-up.

The project evaluation will confirm use of the feedback reports and that the process works as intended to improve CT safety.

Implementation Strategies

  • Adapt the dose optimization program to be more accessible, automated, and useful.
  • Adapt dose optimization protocols for different types of body scans.
  • Develop and use online training courses on quality improvement and best practices for radiation dose optimization.
  • Train radiologists, medical specialists, radiological technologists, and administrators to interpret and use feedback reports.
  • Use a phased implementation approach, refining the program with a small number of sites and then expanding to remaining sites.
  • Provide sites with audit and feedback reports.
  • Provide technical assistance to sites, including consultation.
  • Partner with national stakeholder organizations to promote implementation.

Evaluation Outcomes

Health Conditions Health Conditions These are the broad terms we use to categorize our funded research studies; specific diseases or conditions are included within the appropriate larger category. Note: not all of our funded projects focus on a single disease or condition; some touch on multiple diseases or conditions, research methods, or broader health system interventions. Such projects won’t be listed by a primary disease/condition and so won’t appear if you use this filter tool to find them. View Glossary
