"get up and go test"

16


Urinary incontinece is more common in females (short urethra, child birth), it increases with age, common factor leading to institutionalization/social isolation.

 

What are the four types?
 


»Stress incontinence
»Urge incontinence
»Overflow incontinence
»Functional incontinence
 

17

How do you evaluate urinary incontinence?


»H&P
»Functional alertness/capacity, CHF, abdominal exam (distention), genital exam
»CBC, U/A, blood sugar, imaging (Renal U/S), culture
»Post void residual – evaluation of emptying
 

18

What are the coping strategies for urinary incontinence?


»Pads, hand-held urinals, bed pans, bedside commodes, etc.
»Social isolation
»Foley (indwelling) catheters are a poor choice for management – a last resort
 

19

What are the downsides to the foley catheter?


•Limits mobility and is a safety risk
•Significant cause of infection
 

20

How do we treat urge incontinence?


–Bladder training/toileting schedule
–Medication
»Anticholinergic medication - detrusor muscle instability
»Reduce/eliminate caffeine
»Treat underlying infections
 

21

How do we manage stress incontinence?


–Kegel exercises
–Medications
»Estrogens – some data reveal that oral estrogens make the condition worse
»Alpha adrenergic agonists
–Surgery urethropexy or pubovaginal slings
–Pessary – uterine prolapse
 

22

How do you manage overflow incontinence treatment?


–Post void residual urine volume is elevated


–Fecal Impaction


–Prostatic enlargement – the prostate is always growing in men under the influence of testosterone
» Treatment Medication
•Finasteride
•Alpha adrenergic antagonists


– Treatment with augmented voiding maneuvers
»Suprapubic pressure
»Valsalva maneuver
»Intermittent catheterization
 

23

Constipation is patient specific, decreased frequency of bowel movements for the particular individual, but usually fewer than three evacuations a week.  

What does this include?


–impaction that requires

manual disimpaction, incomplete elimination, painful elimination, dry/hard stool
 

24

What are some of the etiologies of constipation?


•Medication - opiates, anticholinergics, antidopaminergic, calcium channel blockers
•Mechanical obstruction – tumor, prolapse, adhesions
•Neurological – CVA, MS
•Systemic – hypothyroid, diabetes, inflammatory, electrolyte disorders
•Dehydration and inactivity
 

25

How should we evaluate for constipation?


•H&P
–Medications,  fluid intake,  disease history
–Abdominal distention and pain
–Rectal exam – tone, impacted stool, hemorrhoids, strictures, or fissures
–Neurological exam – rectal tone (spinal cord impairment)
•Lab test
–Electrolytes, BUN, creatinine, TSH, calcium
–Colonoscopy – carcinoma?
–Abdominal X-ray
–CT of the abdomen
 

26

What are good treatments for constipation?


•Bulk laxatives
•Osmotic agents
•Enemas
•Stool Softeners
•Hydration
•Maintaining physical activity
 

27

When are bulk laxatives not adviseable?


–The exception is for treatment opiate-induced constipation, need to use peristaltic stimulants
 

28

What are risk factors for pressure ulcers?


–immobility, poor nutritional status, incontinence, vascular insufficiency, altered level of consciousness 
 

29

What are pressure ulcers?

ischemic soft tissue injury usually over a boney prominence

30

The Braden scale is a risk assessment tool.  What are the stages of pressure ulcers?


•Stage 1 - intact skin with non-blanchable redness
•Stage 2 - partial thickness loss, open ulcer or blister with a pink wound bed
•Stage 3 - full thickness tissue loss, subcutaneous tissue present, tunneling and slough
•Stage 4 - full thickness with exposed underlying structures, bone, muscle, tendon
•Unstageable  - covered by slough and/or eschar and underlying structures cannot be visualized
 

31

How do we prevent pressure ulcers?


•Prevention – pressure relieving devices/mattresses, turning and barrier creams while avoiding shearing forces, reduce moisture – diapers 
–catheters can be used in as a last resort; can they lead to UTIs
 

32

How do we treat pressure ulcers?


•Moist dressings (allow for a healing environment), antibiotics for infection, surgical debridement, enzymatic debridement, consider osteomyelitis – non-healing wounds

36

What kind of dangers does sensory impairment present to elderly patients?


–Olfaction loss
•Spoiled food in refrigerator
–Vision loss
•Presbyopia, cataracts, open-angle glaucoma, macular degeneration, diabetic retinopathy
–Hearing loss leads to isolation, frustration of others
