The aims in managing osteoporosis

• TO REDUCE THE INCIDENCE OF FRACTURES• To identify patients at increased risk of fracture• To be able to assess that risk accurately• To give advice to aid understanding of the disease, the aims

of therapy and the choice of therapy• Treatment

• Lifestyle advice• Therapeutic agents

What is the intended use of fracture risk tools?Osteoporosis is a common disease

It should largely be managed in primary care.Experts in osteoporosis are used to integrating information

derived from multiple risk factors, but most primary care physicians in many countries have little expert

knowledge. It is this constituency for which fracture risk tools are primarily

designed To increase awareness and knowledge of osteoporosis and to

initiate appropriate treatment in patients at highest risk of fracture.

NICE SCG Fracture Risk Assessment• Consider assessment of fracture risk in in all women aged

65 years and over and all men aged 75 years and over .

• Consider fracture risk in women <65 years and men <75 years if they have any of the following risk factors:

• Do not routinely assess fracture risk in people <50 years unless major risk factors (e.g. GC use, untreated premature menopause, previous fragility fracture).

• previous fragility fracture• current or frequent use of oral

glucocorticoids• history of falls• family history of hip fracture

• causes of secondary osteoporosis• low BMI (<18.5 kg/m2)• smoking >10 cigarettes per day• alcohol intake > recommend units

Osteoporosis: fragility fracture risk: NICE guideline August 2012

Page 8: Osteoporosis 2016 | Fracture Risk assessment tools: Prof. Eugene McCloskey #osteo2016

• Use either FRAX (without a BMD value) or QFracture to calculate 10-year predicted absolute fracture risk when assessing risk of fracture.

• Do not routinely measure BMD to assess fracture risk without prior assessment using FRAX (without a BMD value) or QFracture.

Risk factors in QFracture-2012/16

• Age • Sex • Ethnicity • Body mass index• Smoking status• Alcohol use • Use of corticosteroids• Parental history of hip

fracture/osteoporosis • Prior osteoporotic fracture (wrist,

spine, hip, or shoulder)• Rheumatoid arthritis or SLE

• History of falls • Dementia/Nursing or care home

residence • Type 1 or Type 2 diabetes • Cancer • Asthma or COPD • Cardiovascular disease • Chronic liver disease • Chronic kidney disease • Parkinson's disease • Gastrointestinal malabsorption • Epilepsy or use of anticonvulsants • Use of antidepressants• Endocrine problems (thyrotoxicosis,

hyperparathyroidism, Cushing’s)

• Use either FRAX (without a BMD value) or QFracture to calculate 10-year predicted absolute fracture risk when assessing risk of fracture in people of between 40 and 84 years.

• Do not routinely measure BMD to assess fracture risk without prior assessment using FRAX (without a BMD value) or QFracture.

• Following risk assessment with FRAX (without a BMD value) or QFracture, consider measuring BMD with DXA in people whose fracture risk is in the region of an intervention threshold for a proposed treatment, and recalculate absolute risk using FRAX with the BMD value

• It is out of the scope of this guideline to recommend

intervention thresholds.o Healthcare professionals should follow local protocols or other

national guidelines for advice on intervention thresholds.

Baseline Information

Randomisation

Low Risk

• Women aged 70-85 years, not on anti-osteoporotic medication identified from GP lists

• 7 geographical regions of the UK

• Randomly allocated to control (usual management) or intervention (screening).

• In those subjects deemed at high risk of hip fracture, family doctor advised to intervene.

• Follow-up for 5 years.

• Osteoporotic fracture as primary endpoint; hip fracture and mortality as secondary endpoints.

Stepwise implementation

Objective 1: Improve outcomes and improve efficiency of care after hip fractures – by following the 6 “Blue Book” standards

Hip fracture patients

Objective 2: Respond to the first fracture, prevent the second – through Fracture Liaison Services in acute and primary care

Non-hip fragility fracture patients

Objective 3: Early intervention to restore independence – through falls care pathway linking acute and urgent care services to secondary falls prevention

Individuals at high risk of 1st fragility fracture or other injurious falls

Objective 4: Prevent frailty, preserve bone health, reduce accidents – through preserving physical activity, healthy lifestyles and reducing environmental hazards

Summary• NICE has endorsed the use of FRAX or QFracture in the

assessment of fracture risk.

• Clinical utility requires assessment thresholds, integration of BMD, intervention thresholds and demonstration of reversibility of risk.

• The SCOOP study demonstrates that a screening program based on FRAX significantly reduces hip fractures.
