Implications for practice and research
Vitamin D deficiency is rampant in institutionalised elderly individuals. Routine high-dose vitamin D3 appears to prevent acute respiratory infections in this population. This clear benefit must be weighed against a higher risk of falls with monthly vitamin D3 doses.
Future research should establish optimised vitamin D supplementation protocols and find the best benefit–risk strategy.

One or all of these factors are often found in nursing home residents, making them one of the most populous risk groups for vitamin D deficiency.
