Managing At-Risk / Special Needs Populations - General
- At-risk / special needs populations require special attention during a radiation incident.
- Health care providers must identify and respect their needs and respond appropriately to them, considering the resources available.
- Selected issues particularly relevant to radiation incidents are discussed below
- General issues are discussed in this CDC document
- Bone marrow reserve diminishes with age
- Predisposition to anemia
- Predisposition to infection
- Predisposition to bleeding
- May have increased risk of bleeding due to medications, poor diet, or other factors
- Increasing number of co-existing diseases and conditions may be associated with
- Inability to tolerate certain drugs
- Lesser ability to tolerate aggressive salvage treatments, such as stem cell transplant for treatment of Acute Radiation Syndrome
- Cognitive issues may need to be addressed
- Seniors (Ready.gov)
- Keeping Older Americans and People with Disabilities Safe and Healthy during Emergencies (HHS/Administration for Community Living)
- Whole body radiation exposure will exacerbate pre-existing diminished immune functions.
- Countermeasures (e.g., myeloid cytokines) used to enhance blood cell production may be less effective.
- Affected individuals are more susceptible to infection.
- These individuals usually require leuko-reduced, irradiated blood.
- May not be able to tolerate radiation-induced prolonged pancytopenia or stem cell transplant due to underlying condition (e.g., cancer, congenital or acquired immune deficiency).

Persons with Disabilities and Other Special Needs
- Patients with diminished mobility may not be able to
- Evacuate the radiation scene as directed
- Tolerate the austere environments required during the emergency
- Mobilize without assistance for transportation or decontamination
- Transportation issues may need to be arranged to accommodate special needs.
- Patients with diminished mental capacity may not be able to follow directions.
- Patients with limited language proficiency or non-English speakers may not be able to follow directions.
- Patients with medical disabilities may not be able to tolerate standard radiation rescue treatments and may be disconnected from chronic treatments such as dialysis, oxygen, insulin, and other chronic medications.
