How often should DEXA be performed in long-term PN patients?

• A. Every 10 years.
• B. Monthly.
• C. Never.
• D. Every 1-3 years.

Answer: (D)

Bone health is a key concern in people on long-term PN because immobility and ongoing mineral/vitamin imbalances can lead to gradual bone loss. A DEXA scan provides objective, repeatable measurements of bone mineral density to track changes over time. Rechecking every 1-3 years strikes a balance: it’s frequent enough to detect meaningful declines and guide treatment, but not so frequent as to expose patients to unnecessary radiation or extra cost. If a patient has higher risk factors, established osteoporosis, or is starting or changing bone-active therapy, more frequent monitoring (for example, annually) may be considered, but the standard interval remains every 1-3 years. Prematurely frequent scans (monthly) or delaying for many years (every 10 years) would be inappropriate given the risk of unnoticed bone loss.
