When Screening Remember...It's Less than 2 minutes that Pay Off!
Question : “Since the last visit..."– " Have you broken any bones? "– " Have you fallen? "– " Have you had prolonged and unusual back pain? "– " Have you received oral or intravenous
steroids (cortisone) "Look
- Is there kyphosis? - Ability to perform the “Get up and Go” Test
Measure the patient’s height
EMR reminder tools may help to prompt screening4

Screening for Osteoporosis: When to do a BMD1
Clinical Note:If you are ordering unrelated imaging (e.g. chest x-ray) for your
patient, consider adding “rule out vertebral fracture” on the order2.
21
There are Two Tools Available for Fracture Risk Assessment
1. OC Guidelines tool available at: http://www.osteoporosis.ca/multimedia/FractureRiskTool/index.html#/Home 2. FRAX® tool available at: http://www.shef.ac.uk/FRAX/tool.jsp 3. National Osteoporosis Foundation guidelines: www.nof.org/professionals/NOF_Clinicians_Guide.pdf
These tools incorporate other clinical risk factors for fracture in addition to BMD

Understanding a Fragility Fracture is Critical
Definition of a fragility fracture*:
A fracture that occurs spontaneously or following a minor trauma such as:– Fall from a standing height (ie, on the ice)– Fall from a sitting position– Fall from a supine position
(bed or reclining deck chair < 1 meter high)– Fall after having missed 1 to 3 steps in a staircase– After a movement outside of the typical plane of motion
or coughing
1. Bessette L, et al. Contemp Clin Trials 2008; 29:194-210.2. Brown JP, et al. J Bone Miner Res 2007;23(suppl 1): M350.
* Fragility fracture includes all bones, except: skull and face, patella, hands and feet, cervical spine
24
Medications known to cause/accelerate bone loss
• Proton Pump Inhibitors (PPI)• Selective serotonin reuptake
inhibitors (SSRIs)• Aromatase inhibitors• Hormonal/endocrine
therapies - (GnRH, agonists, LHRH analogs)
Medications that increase fall risk and potential to fracture
» Benzodiazepines» Neuroleptics» Anticholinergics» Anticonvulsants» Antidepressants» Antihypertensives» Beta-blockers, nitrates,
vasodilators
* Note: not an exhaustive list

Top 5 Reasons to Consider Treatment in the Moderate Risk Patient:
1. Fracture: vertebral (on lateral spine X-ray) or wrist fracture (in patient >65 or BMD ≤ -2.5)
2. Lumbar spine T-score << femoral neck T-score
3. Concurrent high risk disorder or medications, including:• Hypogonadism or premature menopause (age <45 yr)• Primary hyperparathyroidism• Hyperthyroidism• Rheumatoid arthritis• Glucocorticoids (long-term or repeated use)• Aromatase inhibitor therapy
4. Falls (≥2 in the past year)
5. Patient preference to be treated

» Women with a wrist fracture have double the risk of any future osteoporotic fracture1
» Vertebral fracture predicts future hip fracture2
» A hip fracture increases the likelihood ofdeath by 3 fold3 and increases admissions to long term care4
» Vertebral fractures can cause severe, disabling back pain, dowager’s hump5, and increase the likelihood of death within 5 years (~4 times)6
» Therapy could reduce the risk of this happening7

How do I Approach Drug Holiday in Osteoporosis Management?
1. Watts NB & Diab DL. J Clin Endocrinol Met; 2010, 95 (4): 1555-1565 2. Papaioannou A, et al. CMAJ. 2010;182:1864-1873. 3. Black DM et al. NEJM 2012;366:2051-2053. 4. Cummings SR et al. JBMR 2013; 28: 439-441
RECOMMENDATIONS:
Patients at HIGH RISK for fracture should continue therapy2
After 3-5 years of therapy, re-assess your patient1,3-4:
Drug holiday: time off of bisphosphonate therapy, assuming reinitiation in future1.
BMD ≤ -2.5 or fracture or ongoing glucocorticoid therapy
Evaluate Continued Therapy
BMD >-2.5 and no fracture
Consider A Drug Holiday
40
Challenges in Managing Patients on Treatment
41
Learning Objective
Overcome challenges in PMO management.
42
Audience Question:
» If your currently treated patient is not responding to treatment (decrease in BMD) on an oral bisphosphonate, what would you recommend?
A. A different oral bisphosphonate (alendronate/risedronate)
B. A medication with a different mechanism of action (i.e. denosumab, raloxifene)
C. A medication with a different route of administration (i.e. denosumab, zoledronic acid)
D. Continue to monitor her (no change in therapy)
43
Ensure that a Loss in BMD is not due to Secondary Causes of Osteoporosis
What are the recommended Biochemical Tests?» Calcium, corrected for albumin » Complete blood count» Serum creatinine (eGFR) » Alkaline phosphatase» Thyroid stimulating hormone (TSH)» Serum protein electrophoresis for
patients with vertebral fractures» 25-hydroxy vitamin D (25-OH-D)*
* Should be measured after 3-4 months of adequate supplementation
and should not be repeated if an optimal level ≥75 nmol/L is achieved.
1. Papaioannou A, et al. CMAJ. 2010;182:1864-1873.
44
Is your patient failing on treatment?
Treatment failure can be considered after 1 year on therapy if1:- Patient has a decrease in BMD on treatment (4-5%)- Patient has 2 or more fragility fractures on treatment
» Are there any new risk multipliers in your patient’s profile that would increase bone loss?– Change in medications– Co-morbidities
» Consider that lack of adherence could also cause treatment failure
1. Diez-Perez A et al. Osteoporos Int 2012 23:2769-2774
45
Is your patient taking their oral BP properly?
Instructions for taking oral BPs:
In the morning, at least 1/2 hour before breakfast Should remain sitting upright for at least 1 hour Take only with water* Take alone, with no other medications Give only to residents who can swallow effectively Vitamin D and calcium supplements should be taken at a
different time
*Risedronate DR – needs to be taken with food
www.osteoporosislongtermcare.ca
46
Consider Drug Intolerance
» Generic agents may not be as well tolerated as the branded version1
» Risedronate DR – may ease administration burden, however, in the clinical trial the GI events were similar to those seen with Actonel weekly2
– Calcium supplements must be given separately 3
» For patients with osteoporosis using PPIs:– Ensure optimal calcium and vitamin D supplementation and instruct patient
to optimize food intake of calcium
– Prescribe the lowest effective PPI dose and review indication and alternatives periodically
– Consider alternate formulation of calcium (eg, calcium citrate) 1. Papaioannou A, et al. J Clin Densitometry 2008;11:458-459. Abstract 152. 2. McClung MR et al. Osteoporos Int 2012:; 23: 267-276 3. Actonel Product Monograph, Warner-Chilcoott.

Polypharmacy: An Adherence Issue in Osteoporosis Patients
» Patients on osteoporosis medication have a high likelihood of being on multiple medications for other chronic diseases– 40% of women on bisphosphonate therapy are
also on ≥4 other concomitant medications1
» Polypharmacy can decrease adherence rates – Women on several other medications were 21% more
likely to discontinue weekly BPs2

Accessed Nov 30, 2011. 3. Patient Direct, ProVital ™ Program, as at Nov 30, 2011 report. 4. Osteoporosis Canada. Available at: http://www.osteoporosis.ca. Accessed November 2010. 5. Health and Bone. Available at: http://www.healthandbone.ca/en/home. Accessed November 2010. 6. Drug Coverage.ca Available at: http://www.drugcoverage.ca Accessed October 2010.
Consider patient support programs offering services such as nurse support, reimbursement information, dose reminders, and education1,2
Adherence in these programs has been shown to be as high as 94%3

Clinical Pearls
53
Clinical Pearls for Patient Assessment:
1.Have they fallen?
2.Has their BMD decreased (>3%) since their last BMD?
3.Have they lost height? (> 2cm height since last visit or >6 cm historically)
4.Have they broken any bones?
5.Are there any other risk factor multipliers to consider? – If yes: they are at increased fracture risk and should
be further assessed, possibly by a lateral x-ray
54
Clinical Pearls for Who to Treat
» Treat all patients at HIGH RISK for fracture: –Prior hip or vertebral fracture–Multiple fractures–10 yr absolute fracture risk >20%
» Patient at MODERATE RISK for fracture:– Consider additional risk factors– Discuss fracture risk and treatment options with
patient
55
Clinical Pearls for Patient Management
1. Individuals at HIGH RISK for fracture should continue osteoporosis therapy without a drug holiday1
2. Discuss benefit vs. risk of therapy with patients
3. When monitoring patients on therapy, consider:• Long-term efficacy• Safety & tolerability• Adherence• Patient preference
1. Papaioannou A, et al. CMAJ. 2010;182:1864-1873.
56
Final Clinical Pearl
• The goal of PMO treatment and management is preventing a fracture.
Healthy bones are strong bones!
