Radiographer’s Role
Adapt procedures to accommodate disability and disease
Understand physiology and pathology of aging
Be aware of social, psychological, cognitive, and economics of aging

![Page 6: Geriatrics Branch of medicine dealing with aged and problems of aging Geriatric patients are persons over age 65 Population is increasing.](https://reader036.fdocuments.net/reader036/viewer/2022062717/56649e195503460f94b06b17/html5/thumbnails/6.jpg)
Osteoarthritis
Degenerative joint disease caused primarily by wear and tear on joints
Body creates additional bone tissue in response to stress on joints
Can lead to complete fusion of joints
![Page 7: Geriatrics Branch of medicine dealing with aged and problems of aging Geriatric patients are persons over age 65 Population is increasing.](https://reader036.fdocuments.net/reader036/viewer/2022062717/56649e195503460f94b06b17/html5/thumbnails/7.jpg)
Osteoporosis
Loss of bone volume and mass- Often, kVp must be reduced for x-ray exams
4 times more common in women (menopause), but can appear in men
Increased risk of fxs, kyphosis
![Page 8: Geriatrics Branch of medicine dealing with aged and problems of aging Geriatric patients are persons over age 65 Population is increasing.](https://reader036.fdocuments.net/reader036/viewer/2022062717/56649e195503460f94b06b17/html5/thumbnails/8.jpg)
Alzheimer’s Disease
Chronic, organic mental disorder
Due to atrophy of frontal and occipital lobes
Occurs between ages 40 and 60
Progressive loss of memory leads to complete loss of intellectual function
![Page 9: Geriatrics Branch of medicine dealing with aged and problems of aging Geriatric patients are persons over age 65 Population is increasing.](https://reader036.fdocuments.net/reader036/viewer/2022062717/56649e195503460f94b06b17/html5/thumbnails/9.jpg)

Cardiovascular System Disorders
Most common cause of death worldwide
Loss of arterial elasticity increases systolic blood pressure -greater risk for heart disease and stroke
Postural hypotension - fall in blood pressure when rising from supine to standing position
Atherosclerosis (build up of fatty plaques in arterial walls-increasing risk of aneurysm, blood clot formation- which may cause embolism, heart attack, stroke)
Congestive heart failure - inability of heart to propel blood at sufficient rate and volume
Cerebrovascular Accident (CVA) -stroke

Chest
PA- wrap arms around upright device- increases support and security
Lateral- provide support and stability in moving arms up and forward
Perform exam in wheelchair - note projection change
Hyperkyphosis changes positioning landmarks
![Page 25: Geriatrics Branch of medicine dealing with aged and problems of aging Geriatric patients are persons over age 65 Population is increasing.](https://reader036.fdocuments.net/reader036/viewer/2022062717/56649e195503460f94b06b17/html5/thumbnails/25.jpg)
Spine
Use sponges and table pad
Upright more comfortable if able
Or Seated position may be used for exam requiring upright position
![Page 26: Geriatrics Branch of medicine dealing with aged and problems of aging Geriatric patients are persons over age 65 Population is increasing.](https://reader036.fdocuments.net/reader036/viewer/2022062717/56649e195503460f94b06b17/html5/thumbnails/26.jpg)
Pelvis/Hip
Fxs common -do not rotate limb until fx. ruled out!
Cross-table lateral often more comfortable
In nontrauma pts, sandbags useful to support rotation of limbs
MRI- fx would have been missed by radiograph
![Page 27: Geriatrics Branch of medicine dealing with aged and problems of aging Geriatric patients are persons over age 65 Population is increasing.](https://reader036.fdocuments.net/reader036/viewer/2022062717/56649e195503460f94b06b17/html5/thumbnails/27.jpg)

Pt Care of Elderly
Explain everything you are about to doDecreases pt stress and anxiety
Increases compliance and satisfaction
Treat pt with respect and dignityCommunicate with warmth, empathy, and positive attitude
![Page 30: Geriatrics Branch of medicine dealing with aged and problems of aging Geriatric patients are persons over age 65 Population is increasing.](https://reader036.fdocuments.net/reader036/viewer/2022062717/56649e195503460f94b06b17/html5/thumbnails/30.jpg)
For the hard of hearing:
Give one instruction at a time Reduce background noise Speak slowly, distinctly, and directly to pt
Not all elderly patients are hard of hearing Adjust voice volume as needed
![Page 31: Geriatrics Branch of medicine dealing with aged and problems of aging Geriatric patients are persons over age 65 Population is increasing.](https://reader036.fdocuments.net/reader036/viewer/2022062717/56649e195503460f94b06b17/html5/thumbnails/31.jpg)
Exposure time becomes more critical
Why use shorter times?
- reduce risk of imaging involuntary and voluntary motion
- elderly may have difficulty maintaining required position
Breathing instructions must be carefully communicated and practiced
![Page 32: Geriatrics Branch of medicine dealing with aged and problems of aging Geriatric patients are persons over age 65 Population is increasing.](https://reader036.fdocuments.net/reader036/viewer/2022062717/56649e195503460f94b06b17/html5/thumbnails/32.jpg)
Technical factors
Adjust to accommodate disease and normal age-related changes
Radiographer must know whether disease/change is additive or destructive
Emphysema
![Page 33: Geriatrics Branch of medicine dealing with aged and problems of aging Geriatric patients are persons over age 65 Population is increasing.](https://reader036.fdocuments.net/reader036/viewer/2022062717/56649e195503460f94b06b17/html5/thumbnails/33.jpg)
Patient Care of Elderly
Provide rest time between projections and procedures
Avoid use of adhesive tape-Can easily damage skin
Use table pads, blankets, sponges, and hand rails-
Increases comfort and compliance

Pt Care of Elderly: Quick Tips cont’d
Carefully check pt history before administering contrast!
Reduces adverse reactions: -dehydration, induced kidney failure
Assess for swallowing difficulty
Administer drinking liquids in upright position to reduce risk of aspiration
![Page 35: Geriatrics Branch of medicine dealing with aged and problems of aging Geriatric patients are persons over age 65 Population is increasing.](https://reader036.fdocuments.net/reader036/viewer/2022062717/56649e195503460f94b06b17/html5/thumbnails/35.jpg)
Conclusion:
Successful imaging of elderly pts depends upon radiographer’s competence and knowledge of this special population
