Admission to hospital - 5 times
32% admitted
ICU Admission - 5 times
7% admitted to ICU
Ambulance Service - 4 times
30% use ambulance
Comprehensive ED Care - 6 times
46% comprehensive care Ann Emerg Med 1992;21:819-824.

ED Environment
Uncomfortable for older persons
High volume, high stress
Anxious, worried patients
Little privacy
Limited ED provider time
Beds, lighting, noise
Modifications can make a difference

Attitudes and Ageism
Negative View of Aging
language
frail, disabled elderly
nursing home patients
distorted view of elderly persons
Aging - deterioration to be avoided and feared

Principles of Geriatrics Emergency Medicine
1. The patient’s presentation is frequently complex.
2. Common diseases present atypically in this age group.
3. The confounding effects of co-morbid diseases must be considered.
4. Polypharmacy is common and may be a factor in presentation, diagnosis, and management.
5. Recognition of the possibility for cognitive impairment is important.
6. Some diagnostic tests may have different normal values.
![Page 14: Approach to the Elderly Patient in the ED - Brown](https://reader035.vdocuments.us/reader035/viewer/2022081511/62a4ba666ffa1c5bc82ac586/html5/thumbnails/14.jpg)
Principles of Geriatrics Emergency Medicine
7. The likelihood of decreased functional reserve must be anticipated.
8. Social support systems may not be adequate, and patients may need to rely on caregivers.
9. A knowledge of baseline functional status is essential for evaluating new complaints.
10. Health problems must be evaluated for associated psychosocial adjustment.
11. The emergency department encounter is an opportunity to assess important conditions in the patient’s personal life.

Confusion Assessment Method Worksheet
I. ACUTE ONSET OR FLUCTUATING COURSE
Is there evidence of an acute change in mental status from the patient’s baseline? OR Did the (abnormal) behavior fluctuate during the day (i.e., tend to come and go or increase and decrease in severity)? NO YES II.INATTENTION Did the patient have difficulty focusing attention (e.g.,
being easily distractible or having difficulty keeping track of what was being said)? NO YES
![Page 22: Approach to the Elderly Patient in the ED - Brown](https://reader035.vdocuments.us/reader035/viewer/2022081511/62a4ba666ffa1c5bc82ac586/html5/thumbnails/22.jpg)
III. DISORGANIZED THINKING
Was the patient’s thinking disorganized
or incoherent (e.g., rambling or irrelevant
conversation, unclear or illogical flow of
ideas, or unpredictable switching from
subject to subject)? No Yes
![Page 23: Approach to the Elderly Patient in the ED - Brown](https://reader035.vdocuments.us/reader035/viewer/2022081511/62a4ba666ffa1c5bc82ac586/html5/thumbnails/23.jpg)
IV. ALTERED LEVEL OF CONSCIOUSNESS Overall, how would you rate the patient’s level of
consciousness? ____ Alert (normal) ____ Vigilant (hyperalert) ____ Lethargic (drowsy, easily aroused) ____ Stupor (difficult to arouse) ____ Coma (unarousable) Do any checks appear in this box? No Yes From Inouye SK, van Dyck CH, Alessi CA, et al. Clarifying confusion:

Repeat these words:
APPLE – TABLE – PENNY
May repeat 3 times if necessary

6. Some diagnostic tests may have different normal
values
Labs Unchanged* Hemoglobin and Hematocrit WBC Platelet count Electrolytes (sodium,
potassium, chloride, bicarbonate)
BUN Liver function tests
(transaminases, bilirubin, prothrombin time)
TSH Calcium Phosphorus * Aging changes do not occur in these
parameters; abnormal values should prompt further evaluation.
Common Abnormal Labs† ESR Creatinine Alkaline phosphatase UA Glucose Albumin D dimer †Includes normal aging and other
age-related changes.

In addition…
Not all elderly are the same
Heterogenous and diverse group
Physiologic rather than biologic age should guide care
![Page 33: Approach to the Elderly Patient in the ED - Brown](https://reader035.vdocuments.us/reader035/viewer/2022081511/62a4ba666ffa1c5bc82ac586/html5/thumbnails/33.jpg)
Physiology of Aging
Normal aging is benign
Associated with decline of body reserve
Usually does not causes problems until disease occurs
![Page 34: Approach to the Elderly Patient in the ED - Brown](https://reader035.vdocuments.us/reader035/viewer/2022081511/62a4ba666ffa1c5bc82ac586/html5/thumbnails/34.jpg)

Recommendations
Sit down and talk to the patient and/or family
Call the nursing home/assisted living home/pcp/family for baseline function if patient unable to provide
Avoid foley use if possible
Do not treat asymptomatic pyuria
![Page 36: Approach to the Elderly Patient in the ED - Brown](https://reader035.vdocuments.us/reader035/viewer/2022081511/62a4ba666ffa1c5bc82ac586/html5/thumbnails/36.jpg)
Take Home Points
Elderly patients possess unique pathophysiologic and clinical concerns that require special management principles.
Optimal emergency care of elderly patients requires a more comprehensive model of care that takes into account the patient’s biological, functional, cognitive and social support status in assessing and discharge planning.
Remember to screen for delirium in mental status change (CAM) and cognitive impairment in all elder patients (SIS).
