The Claim
In elderly long-term care residents who have fallen, orthostatic hypotension occurs in approximately 15.4% of falls.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Among elderly residents in long-term care who have fallen, orthostatic hypotension is present in about 15 out of every 100 falls.
See the scientific wording
In elderly long-term care residents who have fallen, orthostatic hypotension occurs in approximately 15.4% of falls (18 of 117 falls), indicating that this condition is a relatively common consequence of falls in this high-risk population.
When a person stands up, blood pools in the legs due to gravity, and the body normally responds by tightening blood vessels and increasing heart rate to keep blood pressure stable. In elderly individuals, this response is weaker because the nerves that control blood vessel tightening become less sensitive, the heart does not pump as forcefully, and blood vessels lose their ability to contract quickly. This causes blood pressure to drop when standing, leading to dizziness or fainting.
What the research says
1 studyStudy: Clinical Risk Factors for Orthostatic Hypotension: Results Among Elderly Fallers in Long-Term Care
The study found that out of 117 falls in elderly nursing home residents, 18 caused a drop in blood pressure when standing—exactly 15.4%, which is about 1 in 6 falls. So the claim is correct.
