What does evidence say about alternating-air mattresses reducing pressure injuries in hospitals?

• A. Lack evidence for reducing pressure injuries in hospitals.
• B. They dramatically reduce injuries in all hospital settings.
• C. They are not studied.
• D. They worsen outcomes.

Answer: (A)

The key idea is that the overall evidence does not show a clear, consistent reduction in hospital-acquired pressure injuries from alternating-air mattresses. Pressure injuries are influenced by many factors, and while these mattresses can help redistribute pressure, the results across studies are mixed and not universally convincing for all hospital populations. Some research suggests possible benefit in certain high-risk or long-stay groups, but other trials find little to no effect, so there isn’t strong, generalizable evidence that they reliably reduce injuries in all hospital settings. They also aren’t widely discouraged by evidence, since they don’t typically worsen outcomes, but the blanket claim of a universal, dramatic reduction isn’t supported.
