Q

How is the Timed Up and Go and Turn 180 Test carried out?

A

Timed Up and Go

Time the person getting up from a chair without using their arms, walking 3 metres, turning around, returning to the chair, and sitting down. If the person usually uses a walking aid, this can be used during the test.

Observe postural stability, gait, stride length, and sway

Score of 12—15 seconds or more indicates high risk of falls

Turn 180

Ask person to stand up and step around until they are facing the opposite direction. If the person takes more than four steps, further assessment should be considered

Q

What are some fall prevention strategies used to reduce falls in hospital?

A

Whilst in hospital:

  • Mobility assessment e.g rotunder, walk
  • Bed alarm
  • Assistance out of bed
18
Q

A
  • Regular medication reviews
  • Regular eye testing
  • Balance training and Falls Prevention Programmes (backward chaining)
19
Q

A
  • Vitamin D deficiency/Osteomalacia
  • Hyperparathyroidism
  • Paget’s Disease
20
Q

If a patient has raised Calcium or bone pain, what differentials do you need to consider?

A
  • Fracture
  • Metastases to bone
  • Primary malignancy of bone
21
Q

What are the phases of bone loss in women?

A

Phase 1

  • Predominantly in trabecular bone
  • Starting at menopause
  • Menopause related bone loss
  • Reduction in BMD is about 10%

Phase 2

  • After 4-8 years, slower loss of both trabecular and cortical bone, usually just reduced bone formation
  • Age related bone loss, which is the only phase that also happens in men.

Osteoporotic fractures take place in temporal sequence, lower end of radius starting at age 50 years, followed by vertebral fractures at age 60-75 years and hip fractures beginning in the late 70s

22
Q

What investigations should you do for a bone health assessment?

A
  • History and Exam: weight, height
  • Bloods (look for metabolic bone disease): U+Es, Calcium, Phosphate, Alkaline Phosphatase, TFTs, Vitamin D
  • Q-Fracture Score (aged 33-99): Set of fracture risk factors, 10-year probability of hip fracture and major osteoporotic fracture (clinical spine, forearm, hip or shoulder fracture)
  • FRAX Score (aged 40-90): Do a DEXA scan for BMD if score 10% or more. If already had fragility fracture this confirms osteoporosis so no DEXA needed
23
Q

What are some risk factors for osteoporosis?

A
  • Age
  • Female
  • Smoking
  • Alcohol
  • Steroid use
  • Low BMI
  • Fragility fracture in a parent
24
Q

What is the difference in Z and T scores from a DEXA scan and how do you interpret these scores?

A
  • T-Score: how many standard deviations away the BMD is from an average 30 year old of the same sex and ethnicity
  • Z-Score: how many standard deviations away the BMD is from the average BMD of people your own, sex and ethncity

If a male and <50 or a premenopausal woman then you only get a Z-Score

25
Q

What are some drugs that can cause bone loss?

A
  • Glucocorticoids >3/12
  • Depo
  • Aromatase Inhibitors
  • Glitazones
  • PPIs
26
Q

When should you order a DEXA scan?

A

The following groups of people should have their 10 year fracture risk calculated using a tool such as FRAX or Qfracture:

  1. All men >75
  2. All women >65
  3. All men and women >50 if they have:
  • Family history of hip fracture
  • Falls history
  • Previous fragility fracture
  • Low BMI
  • Drink >4U per day of alcohol
  • Are/were on steroids
  • Disease associated with osteoporosis (e.g. Coeliac disease, inflammatory bowel disease, hyperparathyroidism)
27
Q

How often should you repeat a DEXA scan?

A
28
Q

How is osteoporosis managed?

A

Non-Pharmacological

  • Advice adequate intake of Ca and Vit D
  • Advice physical activity
  • Advice stop smoking and cut down alcohol
  • Falls Prevention Programme
  • Hip protectors in nursing home patients

Pharmacological

  • Weekly Bisphosphonates
  • Adcal D3
  • Denosumab
  • Raloxifene (post-menopausal women)
  • HRT
  • Strontium Ranelate
29
Q

What are some examples of bisphosphonates, how do they work and what are the side effects?

A

Examples: Alendronic Acid (PO), Zolendronic Acid (IV/SC)

MOA: Absorbed onto hydroxyapatite crystals causing apoptosis of osteoclasts so reduced rate of bone turn over

SE: Ulcers, AF, Jaw Osteonecrosis, Risk of atypical stress fractures

30
Q

What instructions would you give a patient when starting them on bisphosphonates?

A
  • Take once a week on same day
  • Take first thing in the morning before any other tablets, food or drink
  • Drink full glass of water with it
  • Sit up for 30 minutes after taking (reduce risk of oesophageal ulcers)
  • Do not eat or take any other drugs until 30 minutes after
  • Have regular dental check ups
31
Q

What is a bisphosphonate holiday?

A
  • Think about a 2 year holiday after 5 years of Alendronic Acid and 3 years after Zolendronic Acid
  • Risk of osteonecrosis of the jaw and external auditory canal and atypical femoral fractures if continuing bisphosphonates
  • Bisphosphonate stays in the body for a few years so still has an effect
32
Q

What is the mechanism of the following second line drugs for osteoporosis:

  • Denosumab
  • Raloxifene
  • Teriparatide
  • Strontium ranelate
A

Denosumab: monoclonal antibody which inhibit receptors which, when activated, lead to the maturation of osteoclasts

Raloxifene: In post menopausal women, SERM, binds to oestrogen receptors

Teriparatide: PTH that stimulates bone growth

Strontium ranelate: reduced rate of bone turnover and stimulates bone growth

Can also use HRT to be protective against osteoporosis

33
Q

When a patient has a fall, what are the main drugs you should be looking out for in their drug history?

A
  • Sedatives
  • Opiates
  • CVS drugs
  • Anticholinergics
  • Hypoglycaemics
34
Q

What are some Fall Risk Assessment tools?

A
  • TUG
  • 30 Second Stand Chair test
  • 4 stage balance test

ALWAYS ASK ABOUT OTHER RECENT TOOLS

35
Q

What Falls Screening is done in UHL and what patients is it done on?

A
36
Q

Which patients are started on osteoporosis treatment?

A
  • If >75 with fragility fracture then straight away
  • If <75 do DEXA and start if T-Score <2.5
37

What is polypharmacy?

A

6 drugs or more!

Use STOPP/START tool

38

What is Pitozifen?

A

A

Drug for migraine prophylaxis

Can cause dizzy and drowsiness so risk of falls
