Controversies in Osteoporosis Treatment of Nursing Home Residents.

PMID 36335990WHAT IT FOUND
Vitamin D plus calcium may help ambulatory residents, but prescription osteoporosis drugs have limited fracture evidence in nursing homes.
Treatment should weigh mobility, life expectancy, swallowing burden, and goals of care.
Key findings
01Vitamin D alone is unlikely to reduce fractures, but vitamin D plus calcium was associated with reduced fractures in older adults, with benefits most likely in frail nursing home residents.
02Randomized trials in nursing home or assisted living residents showed bone mineral density increases, but neither was powered to detect differences in fractures, falls, or deaths.
03In about 10,000 long-stay nursing home residents, bisphosphonate initiation compared with calcitonin was associated with a modest reduction in hip fractures over 2.5 years, with time to benefit as early as 6 months.

What it does not show
The article is a narrative and scoping review, not a new trial, so it cannot show how much any treatment prevents fractures in frail nursing home residents. The nursing home medication trials described measured bone density, not fractures, falls, or deaths, and were not powered for those outcomes. The two nursing home vitamin D and calcium studies included relatively healthy, ambulatory residents and excluded people with severe conditions or bone-altering medications, so they may not represent typical nursing home residents. Guideline evidence is often extrapolated from community studies or expert consensus, and U.S. nursing home guidelines were last updated in 2009. Observational Medicare studies can be affected by residual confounding, incomplete care-transition data, and limited follow-up.
The easy way to misread this
Do not read the bone density results as proof that osteoporosis medications prevent fractures in frail nursing home residents. The nursing home trials were not powered to detect differences in fractures, falls, or deaths.
