5. Skin problems & ageing
70% of older people have a skin problem
One of the most common reasons people
present in primary care
Ageing reduces cell replacement, skin
thins, melanocytes reduced
Loss of elastin, collagen, fat
Lifestyle factors, smoking, sun damage,
nutrition
General health
Skin barrier less effective and skin more
vulnerable
6. Skin changes in older people
Change Consequence
Skin thins More easily damaged, increase risk of bruising and
skin tears
Replacement rate slows Takes longer to heal
Reduced melanocytes Burns more easily
Loss of collagen Saggy wrinkly skin
Increased risk of skin tears, increased healing time,
wounds more prone to breaking down
Loss of fat Prominent veins, increased risk of bruising
Reduced protective layer, increased risk of skin
damage, increased risk of pressure sores.
Loss of lipids and water Dry skin, cracks easily
Increased risk of infection

11. Mrs Krol’s perspective
“ I’d like some therapy as I’m
struggling to get out of the chair. I
want to be able to get in & out of the
car, shop and meet friends at church.
This itching is driving me mad and
affecting my sleep. If only I could
sleep”
12. Mrs Newton’s hopes and
aspirations
“ A good night’s sleep. I’m exhausted,
haven’t slept in months. Its getting me
down.
To be able to walk a bit better, I’m
struggling to get out of my chair and I’m
getting stiffer and stiffer”
13. Pruritus
Pruritus is derived from the Latin verb
prurire which means to itch.
Pruritus is the most common skin
problem in older people.
Itching may be caused by dry skin but
in 50% of cases itching has an
underlying systemic cause
17. The importance of history
Onset, provocation, palliation and
comorbidities
Onset – fast likely infestation, medication,
allergy. Slow – systemic
Provocation- dry skin bathing, scabies worse
evening and night
Is anyone else itching?
New medication? Herbal, OTC, Chinese
18. Physical examination
Widespread or localised itch?
Local consider contact dermatitis,
rubber, nickel, fragrance, preservatives
Widespread consider systemic causes
Check for rash
Check for scratch marks
19. Clinical findings
Intense itch
Worse when she’s hot and in the evening
Generalised rash, hands, webs of fingers,
wrists, elbows, front of chest, between
shoulder blades and around waist
Dry crusted scabs& areas fresh bleeding
Small black dots visible with magnifying glass
22. Mode transmission
Prolonged skin contact- 5-10 minutes- crawls
one to another
Burrows into skin within 30 minutes
Lays eggs, two a day
Around 4-6 weeks after contact symptoms
appear- itch then rash
Mite tunnels show fine dark or silvery lines
Itch caused by reaction to faeces of mite
23. Diagnosis
Can be difficult
Skin scraping with blunt scalpel and
checked under microscope
For non experts press selotape over
lesion and peel off – send to lab
24. Treatment considerations
Type of scabies
Is the person at home, in a care home
or a hospital
Is this a single case or an outbreak
Do contacts need to be treated
26. Classical scabies
Usual treatment – permethrin 5% cream or
malathion 0.5% lotion
Use gloves
Apply to all parts of body
Adult at least 30g tube larger adults 60g
Lotion at least 100ml
Leave 24 hours and wash off
Repeat in one week – treatment doesn’t kill
eggs.
27. Norwegian scabies
Treated by specialists
May be treated with a combination
of an oral product Ivermectin and 2-
3 applications of topical treatment
on consecutive days
29. Aims of treatment
Treat infestation
Treat itch
Treat sore skin
Provide information,
advice and assurance
Improve quality of life
30. Mrs Krol’s medication
Non sedating anti-histamines ineffective
Chlorphenamine (Piriton) sedative anti-
histamine can cause drowsiness, increase
risk of falls and the risk of urinary retention
Chlorphenamine 4mg at night if required
helped
Hydrocortisone 1% topically BD x 7 days
31. Patient progress
Treated with permethrin 5% cream twice
once and then 7 days later itching resolved
after 3-4 weeks
Provided with leaflet – to explain condition
Upset at thought she could have infected
family especially great grandson
No family members had symptoms
Able to sleep through the night
Physiotherapy to improve mobility
OT provided chair raisers
32. Making a difference: The value of
nurses practicing at advanced level
“I thought I was just going to get
worse and worse but now once
more I have hope and can have a
good life”
33. Take home messages
We use evidence based practice because it
works
All patients regardless of age, cognitive
status or discharge destination deserve the
dignity of a diagnosis
Working with the patient can enable us to
help the person to have the best possible
quality of life
And that’s why we do what we do and why we
make a difference
