ACR Radiography and Fluoroscopy Accreditation

Who is the ACR?

We serve more than 32,000 radiology professionals nationwide

• Diagnostic / interventional radiologists

• Radiation oncologists

• Medical physicists

• Nuclear medicine physicians

• Clinical researchers

Accreditation Programs

• 1966 - first practice accreditation program

• 1987 – mammography accreditation

• 1987 – radiation oncology

• 1994 – FDA adopts ACR’s mammography accreditation program

• 1995 – ultrasound

What is ACR Accreditation?

Peer review process developed and monitored by experts

• Concept must be approved by the ACR Council

• Assesses specific parameters for each imaging modality

• Based on ACR Practice Guidelines and Technical Standards

• Pilot tested before being launched

• Ongoing review of accreditation program by the committee

Diagnostic Modality Accreditation Program

Streamlined application process

• Single application for group practice

• 10 percent discount for each facility that applies for three or more

modalities

• Each facility will have the option of submitting the clinical and phantom

images for different modalities all at once or in 30-day increments

• ACR web site will list all modalities accredited at each practice


ACR Practice Guidelines and Technical Standards

• Evidence based

• Jointly developed

• Good risk management tools


Medical expertise

• Practice Guidelines and Technical Standards Development– Over 450 members participate

• Accreditation Development and Implementation– Over 400 radiologists, radiation oncologists, and medical physicists


ACR Quality and Safety staff

Radiography/Fluoroscopy Accreditation ProgramAccreditation Granted

• All units at the site must pass evaluation for accreditation to be

maintained

• A certificate and decal will be issued for each unit

• Accreditation is granted for three years

Radiography/Fluoroscopy Accreditation ProgramIf the site does not pass the first time

• Retest

– A facility will have the option to retest

• Appeal

– Sites have the option to appeal the final outcome

– The films are reviewed by a senior reviewer, not involved with the first

review

Why ACR Accreditation?

Improved quality

• Patient confidence– Better informed patients are seeking high quality care

• Health care and the Internet:

– 73 million Americans use the Internet to answer health questions

– 68 percent say the material found “influenced” their medical decisions!
