USPSTF Recommendations: Screening for Osteoporosis to Prevent Fractures

SUMMARY:  

The USPSTF released recommendations update for osteoporosis screening to prevent fractures (2018).  The following guidelines are based upon an assessment of benefits vs harms and does not include cost analysis.

• USPSTF Recommendations
• Clinical risk factors in postmenopausal women <65 years of age
• Clinical risk assessment tools
• Screening Tests
• Additional Related USPSTF Recommendations
• Other Professional Recommendations

USPSTF Recommendations

Women ≥ 65 years and older 

• The USPSTF recommends screening for osteoporosis with bone measurement testing to prevent osteoporotic fractures (B recommendation)
  • • Offer or provide this service
  • There is high certainty that the net benefit is substantial

Women <65 years and postmenopausal  

• The USPSTF recommends screening for osteoporosis with bone measurement testing to prevent osteoporotic fractures in women who are at increased risk, as determined by a formal clinical risk assessment tool (B recommendation)
  • Offer or provide this service
  • There is high certainty that the net benefit is substantial 
• The USPSTF concludes that the current evidence is insufficient to assess the balance of benefits and harms of screening for osteoporosis to prevent osteoporotic fractures in men (I statement)
  • The USPSTF concludes that the current evidence is insufficient to assess the balance of benefits and harms of the service
  • Evidence is lacking, of poor quality, or conflicting, and the balance of benefits and harms cannot be determined

KEY POINTS:  

Clinical Risk Factors in Postmenopausal Women <65 Years of Age 

• If ≥1 risk factor, “a reasonable approach” is to use a clinical risk assessment tool (see below)  
• Clinical risk factors include  
  • Parental history of hip fracture 
  • Smoking 
  • Excessive alcohol consumption 
  • Low body weight

Clinical risk assessment tools 

• In the previous guideline (2011), FRAX was the clinical risk assessment tool of choice 
  • Current (2018) guidance now includes others  
• The following tools perform similarly and are moderately accurate at predicting osteoporosis 
  • The Simple Calculated Osteoporosis Risk Estimation (SCORE) 
  • Osteoporosis Risk Assessment Instrument (ORAI) 
  • Osteoporosis Index of Risk (OSIRIS) 
  • Osteoporosis Self-Assessment Tool (OST) 
• FRAX tool (University of Sheffield) 
  • Assesses a person’s 10-year risk of fracture 
  • Includes questions about previous DXA results but not required to assess risk 

USPSTF states that one approach is to  

• Perform bone measurement testing in postmenopausal women younger than 65 years who have a 10-year FRAX risk of major osteoporotic fracture (without DXA) greater than that of a 65-year-old white woman without major risk factors 
• Example, using white woman of mean height and weight  
  • 65-year-old without major risk factors: 10-year FRAX risk of major osteoporotic fracture of 8.4% 
  • 60-year-old with a parental history of hip fracture: 10-year FRAX risk of major osteoporotic fracture of 13%  
• A particular risk factor or a certain age does not represent a particular risk threshold 
• Multiple risk factors at a younger age may indicate that the risk-benefit profile is favorable for screening with bone measurement testing

Screening Tests 

• Central DXA (most common) 
  • Measures BMD at the hip and lumbar spine 
  • Used for most professional treatment guidelines (based on entry criteria for study enrollment) 
• Peripheral DXA 
  • Measures BMD at the lower forearm and heel 
  • Due to portable device measurement, may provide access when central DXA is not available  
• Quantitative ultrasound (QUS) 
  • Evaluates peripheral sites  
  • Similar accuracy in predicting fracture risk as DXA 
  • Avoids radiation exposure 
  • Does not measure BMD and therefore prior to routine use, a conversion method to the DXA scale is needed

Additional Related USPSTF Recommendations 

• Preventing falls 
  • The USPSTF recommends exercise interventions to prevent falls in community-dwelling adults 65 years and older at increased risk of falls  
  • Selectively offer multifactorial interventions based on circumstances of prior falls, presence of comorbid medical conditions, and the patient’s values and preferences  
  • USPSTF recommends against Vitamin D supplementation to prevent falls 
• Preventing fractures  
  • USPSTF recommends against supplementation with 400 IU or less of vitamin D and 1000 mg or less of calcium in postmenopausal women to prevent fractures 
  • The USPSTF found insufficient evidence on supplementation with higher doses of vitamin D and calcium, alone or combined, to prevent fractures in postmenopausal women, or at any dose in men and premenopausal women

Other Professional Recommendations 

• National Osteoporosis Foundation  
  • Recommends BMD testing in all women 65 years and older and all men 70 years and older 
  • Recommends BMD testing in postmenopausal women younger than 65 years and men aged 50 to 69 years based on their risk factor profile, including if they had a fracture as an adult 
• The International Society for Clinical Densitometry  
  • Recommends BMD testing in all women 65 years and older and all men 70 years and older 
  • Recommends BMD testing in postmenopausal women younger than 65 years and men younger than 70 years who have risk factors for low bone mass 
• American Academy of Family Physicians (as part of Choosing Wisely)  
  • Recommends against DXA screening in women younger than 65 years and men younger than 70 years with no risk factors 
• ACOG
  • Recommends BMD testing with DXA in postmenopausal patients 65 years and older
  • Recommends selective screening in postmenopausal women younger than 65 years who have osteoporosis risk factors as determined by  formal clinical risk assessment tool
• American Association of Clinical Endocrinologists 
  • Recommends evaluating all women 50 years and older for osteoporosis risk and considering BMD testing based on clinical fracture risk profile 
• Endocrine Society  
  • Recommends screening in men older than 70 years  
  • Recommends screening adults  
    • 50 to 69 years with significant risk factors 
    • Fracture after age 50 years
