§485.635(b)(3) Radiology services
Radiology services furnished by the CAH are
provided by personnel qualified under State law, and do not expose CAH patients
or personnel to radiation hazards.
Interpretive Guidelines §485.635(b)(3)
Radiologic services encompass many different modalities used for the purpose of medical
imaging. Each type of technology gives different information about the area of the body
being studied or treated, related to possible disease, injury, or the effectiveness of medical
treatment. All the modalities use some form of radiation, such as ionizing radiation
(radiography, computed tomography, fluoroscopy), which has enough energy to
potentially cause damage to DNA, and other forms of radiation (ultrasound, magnetic
resonance imaging) to view the human body in order to diagnose, monitor, or treat
medical conditions.
Radiological services furnished by the CAH may be provided by CAH staff or under
arrangement. The CAH must maintain and have available diagnostic radiological
services to support the services the CAH provides to meet the needs of its patients. These
services must be available at all times the CAH provides services, including emergency
services. The CAH has the flexibility to choose the types and complexity of radiologic
services offered. They may offer only a minimal set of services or a more complex range
of services (including nuclear medicine).
All radiological services provided by the CAH, including diagnostic, therapeutic, and
nuclear medicine, must be provided in accordance with acceptable standards of practice
and must meet professionally approved standards for safety. The scope and complexity
of radiological services offered should be specified in writing and approved by the
governing body (or responsible individual).
Acceptable standards of practice include maintaining compliance with appropriate
Federal and State laws, regulations and guidelines governing radiological services,
including facility licensure and/or certification requirements, as well as any standards and
recommendations promoted by nationally recognized professions such as the American
Medical Association, Radiological Society of North America, Alliance for Radiation
Safety in Pediatric Imaging, American Society of Radiologic Technologists, American
College of Cardiology, American College of Neurology, American College of
Physicians, American College of Radiology, etc.
Qualified Radiologic Personnel
There must be written policies that are developed and approved by the governing body or
responsible individual and are consistent with State law, that designate which personnel
are qualified to use the radiological equipment and administer procedures.
When telemedicine is used to provide teleradiology services, radiologists who interpret
radiological tests must satisfy the telemedicine privileging requirements §485.616(c)(3).
In addition to radiologists, there are other types of healthcare personnel who, depending
on State law and the scope and complexity of the CAH’s radiologic services, may be
involved in the delivery of radiologic services in the CAH, including radiologic
technologists and medical physicists. Radiologic technologists perform diagnostic
imaging examinations and administer radiation therapy treatments. They are educated in
anatomy, patient positioning, examination techniques, equipment protocols, radiation
safety, radiation protection and basic patient care.
For Information Only – Not Required/Not to be Cited
Well-designed radiologic services include a medical physicist, who, in conjunction
with the person responsible for radiologic services, performs or supervises the pertinent
procedures necessary to assure the safe and effective delivery of radiation to achieve a
diagnostic or therapeutic result. The responsibilities of the medical physicist include:
protection of the patient and others from potentially harmful or excessive radiation;
establishment of adequate protocols to ensure accurate patient dosimetry; the
measurement and characterization of radiation; the determination of delivered dose;
advancement of procedures necessary to ensure image quality; development and
direction of quality assurance programs; and assistance to other health care
professionals in optimizing the balance between the beneficial and deleterious effects
of radiation (www.aapm.org). CAHs are encouraged to involve a medical physicist in
the calibration of the imaging equipment and monitoring of radiation dosage
exposures.
Safety from Radiation Hazards
The CAH must adopt and implement policies and procedures that ensure safety from
radiation hazards for patients and personnel. The CAH must implement and ensure
compliance with its established safety standards. The policies must address at least the
following:
• Adequate radiation shielding for patients, personnel and facilities, which includes:
• Shielding built into the CAH’s physical plant, as appropriate;
• Types of personal protective shielding to be used, under what circumstances,
for patients, including high risk patients as identified in radiologic services
policies and procedures, and CAH personnel;
• Types of containers to be used for various radioactive materials, if applicable,
when stored, in transport, in use, and when disposed;
• Clear signage identifying hazardous radiation areas;
• Labeling of all radioactive materials, including waste, with clear identification of
all material(s);
• Transportation of radioactive materials between locations within the CAH;
• Security of radioactive materials, including determining who may have access to
radioactive materials and controlling access to radioactive materials;
• Periodic testing of equipment for radiation hazards;
• Periodic checking of staff regularly exposed to radiation for the level of radiation
exposure, via exposure meters or badge tests;
• Storage of radio nuclides and radio pharmaceuticals as well as radioactive waste;
and
• Disposal of radio nuclides, unused radio pharmaceuticals, and radioactive waste.
Radiologic Equipment Maintenance
The CAH must have policies and procedures in place to ensure that periodic inspections
of radiology equipment are conducted, and that problems identified are corrected in a
timely manner. The CAH must ensure that equipment is inspected and maintained in
accordance with Federal and State laws and regulations, as applicable, and the
manufacturer’s recommendations. The CAH must have a system in place to correct
identified problems. The CAH must have evidence of its inspections and corrective
actions.
Radiology Records
The CAH radiology records are to be treated in the same manner as any other part of a
medical record. The medical records CoP at §485.638(a)(4)(ii) requires that the CAH
maintain reports of physical examinations, diagnostic and laboratory test results, and
consultative findings.
Survey Procedures §485.635(b)(3)
• Interview the person responsible for radiologic services.
• Ask what radiologic services the CAH offers at its main campus. At off-site
locations ask how the CAH ensures patient needs for radiologic services are
met, if applicable.
• Ask how the CAH ensures that radiologic services are provided consistent
with acceptable standards of practice.
• Safety:
• Determine if the radiologic services staff is familiar with the policies and
procedures related to safety.
• Verify that patient shielding (aprons, etc.) are properly maintained and
routinely inspected by the CAH.
• Observe areas where radiologic testing is done and check for safety problems.
• Verify that hazardous materials are clearly labeled. Review records to verify
that they are tracked, handled and stored properly in a safe manner with the
requisite containers.
• Review records to verify that periodic tests of radiology personnel by
exposure meters or test badges are performed.
• Equipment maintenance:
• Review the inspection records to verify that periodic inspections and
maintenance are conducted in accordance with the manufacturer’s
recommendations.
• Determine whether any problems identified are properly corrected in a
timely manner and the correction is maintained over time.
• Qualified Personnel:
• Are studies interpreted only by qualified staff approved to do so by the CAH’s
governing body or responsible individual?
• Determine which staff are using various pieces of radiological equipment
and/or administering patient procedures. Review their personnel folders to
determine if they meet the qualifications for tasks they perform, as established
in the CAH’s policies and consistent with state law.
• Ask staff to explain the protocol for the procedures/studies they administer.
Ask to see the CAH’s written protocols and verify that the staff is adhering to
them.
