3. Clinical Epidemiology
Background
• Established mortality rates after hip and vertebral fracture
UK, 2000-2010
• After hip fracture:
– Doubled 1-year risk of mortality
– 3 - 4 fold increased in men [1]
[1] Klop C et al. Bone 2014;66:171-77

4. Clinical Epidemiology
Objective
• Update the epidemiology of mortality after fragility fracture,
by
– Age
– Sex
– Major causes of death
– Region
– Ethnicity
– Calendar year

5. Clinical Epidemiology
Methods
• Clinical Practice Research Datalink (2001-2011)
• 7% total UK population
• Aged 50+
• England only
• Linked to death certificates
• Fractures
– Clinical vertebral, Wrist, Hip, Humerus, Rib, Pelvis
• Followed for up to 1 year
• Outcome: death

6. Clinical Epidemiology
Results
• 22929 men, mean age 73 years
• 59446 women, mean age 76 years
• North West (17%)
• Other areas (5%-14%)
• North East / East Midlands (3% each)
• 98% Caucasian
• 11,217 deaths

12. Clinical Epidemiology
Results
• Ethnicity
– Elevated 1.8-fold increased risk among black women
(versus Caucasian women)
• Secular trends
– Unchanged excess mortality post-fracture (2001-2011).

13. Clinical Epidemiology
Conclusion
• 1-year mortality rates after fragility fracture were
• Higher
– Elderly
– Men
– Black women (versus Caucasian)
• Lower
– London (women) vs. most other regions
• Comparable
– Over calendar time (2001-2011)

14. Clinical Epidemiology
Conclusion
• Major causes of death included
– Cardiovascular disease
– Respiratory disease
– Malignant neoplasms
• Future research should focus on targeted
interventions to reduce mortality after fracture
