1
Q
One major risk factor for falls includes _____. The risk for developing a mobility disorder increases with age.
A
problems with mobility
- Mobility disorders range from subclinical to obvious, and within this range, fall risk is elevated.

26
Qs to ask for Patient's thoughts on the cause of the fall
* Was patient aware of impending fall?
* Was it totally unexpected?
* Can the patient recall the exact events of the fall w/o family help
27
circumstances surrounding the fall
* Location and time of day
* Activity
* Situation: alone or not alone at the time of the fall
* **Witnesses**
* Relationship to changes in posture, turning of head, cough, urination, a meal, medication intake
28
associated sx of falls
* _Lightheadedness, dizziness, vertigo_
* _Cardiac_? Palpitations, CP, SOB
* Sudden _focal neurological_ sx (weakness, sensory disturbance, dysarthria, ataxia, confusion, aphasia)
* Aura
* **Incontinence of urine/stool **
29
if the patient lost consciousness after the falls, what Qs should be asked?
* What is **remembered** immediately after the fall?
* Could the patient get up, and if so, how long did it take? - “Help I’ve fallen and can’t get up”!
*** Can loss of consciousness be verified by a witness?**
30
PE for falls
* **VS** - orthostasis (lying, sitting, standing) evaluated for any injuries prior to evaluation
* **Skin** - Turgor (over the chest; other areas unreliable), Pallor, Trauma
* **Eyes** - Visual acuity, Pupils, eye movement
* **CV** - Arrhythmias, Carotid bruits, Signs of aortic stenosis
* **Extremities** - Degenerative joint disease, ROM, Deformities, Fractures, Podiatric problems (calluses; bunions; ulcerations; poorly fitted, inappropriate, or worn-out shoes)
* **Neurological** - Mental status, Focal signs, Muscles (weakness, rigidity, spasticity), Peripheral innervation (especially position sense), Cerebellar (especially heel-to-shin testing), Resting tremor, bradykinesia, other involuntary movements, Observation of gait and balance
* Eval **assistive devices** for hazards - missing tips on canes and walkers, impaired locking devices, or broken footrests on wheelchairs
* **feet & footwear**
31
what is The Functional Reach test
* requires using a yardstick mounted on a wall at shoulder height.
* Pt asked to stand close to the wall at a comfortable stance with an outstretched arms-with the shoulders perpendicular to yardstick.
* Pt instructed to extend arm forward as far as possible without taking a step or losing balance;
* the functional reach is measured along the yardstick in inches
* 6-10 inches - moderate fall risk
* <6 inches - severe fall risk
32
what type of footwear can predispose ppl to trip and fall
* heels, floppy slippers, shoes with slick soles
* Ill-fitting footwear that is too big, without sufficient grip or too much friction, and/or without proper fixation (untied or loosely tied shoes) will also contribute to increasing someone’s fall risk.
33
what type of shoe is less likely to trips and falls?
* Upper shoe should be soft and flexible with smooth lining.
* The toe box should be deep enough to allow for toe wiggle room.
* The sole should be strong and flexible for a good grip.
* The heel should provide a broad base for stability and be no higher than 4 cm.
* Finally, the fastening should provide a stable fit with some flexibility to allow for unusually shaped feet or swelling.
34
potentially modifiable risk factors of falls
* muscle strength, gait and balance, and medication
* visual impairment, depression, pain, and dizziness.
35
General info for Fall Prevention
* Provide PT and education: Gait and balance retraining, Muscle strengthening, Aids to ambulation, Properly fitted shoes, Adaptive behaviors, Rising slowing, using rails, etc
* Alter the environment: Safe and proper-size furniture, Elimination of obstacles (loose rugs, etc.), Proper lighting, Rails (stairs, bathroom)
* Tx Fx Pain, but do not ignore the side effects of treatment
36
what are the best ways to prevent falls?
medication reduction, physical therapy, and home safety modifications
37
how to dx fall and immobility?
**there is no standard diagnostic evaluation**
* Labs: CBC, BMP, UA, or chest radiograph might be appropriate depending on the clinical scenario, especially if _significant cognitive impairment or dementia._
* hemoglobin, chemistry panel, TSH, vit B12 (deficiency linked to proprioceptive problems)
* possibly underlying UTI or pneumonia caused the fall
* imaging: CT/MRI - new or unexplained neurologic findings; r/o stroke, mass, nml pressure hydrocephalus, other structural abnormality.
38
State in which an individual has a limitation in independent, purposeful physical movement of the body or of one or more lower extremities
immobility
39
Goal of all members of the health-care team working with older adults?
optimizing mobility
40
small improvements in mobility can:
1. decrease the incidence and severity of complications,
1. improve the patient's well-being, and
1. decrease the cost and burden of caregiving
41
Causes of Immobility
MSK - Arthritis, Osteoporosis, Fractures (esp hip and femur), Podiatric problems
Neurologic - Stroke, Parkinson disease, Neuropathies, Normal-pressure hydrocephalus, Dementias
CV - CHF, CAD (frequent angina), PVD (frequent claudication)
Pulm - COPD (severe)
Sensory factors - Impairment of vision, Decreased peripheral sensation
Environmental - Forced immobility (in hospitals and nursing homes), Inadequate aids for mobility
Other - Deconditioning (after prolonged bed rest from acute illness), Malnutrition, Severe systemic illness (eg, widespread malignancy), Depression, Drug SE (eg, antipsychotic-induced rigidity), Fear of falling
42
* Acute inflammatory response limited to epidermis
* Presents as irregular area of erythema, induration, edema; - may be firm or boggy
* Pressure areas do not blanch when pressed
* May be different with different skin pigments
* Redness with pressure persists after 30 min; in dark skin the color may be red, blue, or a purple hue
* Often over a bony prominence
* Skin is unbroken
what stage is this pressure ulcer?
Stage I
43
* Extension of acute inflammatory response through dermis to the junction of subcutaneous fat
* Appears as a blister, abrasion, or shallow ulcer with more distinct edges
* Early fibrosis and pigment changes occur
* May look like an abrasion or a blister
what stage is this pressure ulcer
Stage II
44
* Full-thickness skin ulcer extending through subcutaneous fat. This may extend down to but not through the underlying fascia
* The skin may have undermining
* Base of ulcer infected, often with necrotic, foul-smelling tissue
* This presents like a crater and may have undermining of the adjacent tissue
what stage is this pressure ulcer?
stage III
45
* Extension of ulcer through deep fascia, so that bone is visible at base of ulcer
* Osteomyelitis and septic arthritis can be present
* Undermining is even more common and there may be sinus tracts
what stage is this pressure ulcer?
stage IV
46
preventing pressure ulcers
* **Identify** patients at risk
* **Decrease** pressure, friction, and skin folding
* Keep **skin clean and dry**
* **Avoid excessive bed rest**: optimize and encourage function
* **Avoid over-sedation**
* Provide adequate **nutrition and hydration**
47
tx stage I & II presssure ulcers
* Clean wounds with warm, normal saline or water
* Avoid pressure and moisture
* Cover open wounds with dressing
* Prevent further injury and infection - abx if needed (Stage II)
* Manage associated pain
48
tx for stage III
* Debride necrotic tissue: autolytic, chemical, mechanical, sharp, or surgical options
* Cleanse and dress wound
* Cx wound
* Abx
* Manage associated pain
49
tx for Stage IV
* tissue bx for cx
* Abx (likely IV)
* Cleanse and dress wound
* Have surgical consultation to consider surgical repair
