1. What is the QFracture Algorithm?

The QFracture algorithm estimates the 10-year risk of osteoporotic fracture or hip fracture based on multiple risk factors including age, sex, ethnicity, BMI, lifestyle factors, and medical history.

2. How Does the Calculator Work?

The calculator uses the QFracture algorithm which incorporates:

Explanation: The algorithm weights each risk factor differently based on extensive population studies to provide an individualized risk assessment.

3. Importance of Fracture Risk Assessment

Details: Identifying individuals at high risk of osteoporotic fractures allows for targeted interventions like bone density testing, lifestyle modifications, and pharmacological treatments to prevent fractures.

4. Using the Calculator

Tips: Enter all required information accurately. The calculator is valid for adults aged 30-99 years. Results should be interpreted in clinical context.

5. Frequently Asked Questions (FAQ)

Q1: How accurate is QFracture?
A: QFracture was developed and validated on large UK populations and shows good discrimination for fracture prediction.

Q2: What's considered high risk?
A: Generally, ≥10% 10-year risk for major osteoporotic fracture or ≥3% for hip fracture may warrant intervention.

Q3: How often should risk be reassessed?
A: Every 2-5 years depending on initial risk level and whether new risk factors develop.

Q4: Can this be used for all ethnicities?
A: The algorithm includes ethnicity adjustments but may be less accurate for populations not well represented in the development dataset.

Q5: Does this replace bone density testing?
A: No, it helps identify who might benefit from further assessment with DXA scanning.
