How often should you reposition someone to prevent pressure ulcers?

It depends on risk, but there are benchmarks

Pressure ulcers develop when an area of skin and the tissue under it is starved of blood by sustained pressure, often over a bony point like the heel, hip or base of the spine. For someone who cannot move themselves, the single most effective prevention is regular repositioning.

There is no one-size-fits-all interval, because it depends on the person. But NICE guidance gives clear benchmarks:

• For adults at risk, reposition at least every six hours.
• For adults at high risk, reposition at least every four hours.
• More often than that if the skin is already showing early signs, such as redness that does not fade.

The frequency should be set by the person’s skin assessment, their mobility and their comfort, and reviewed as their condition changes.

Doing it is half the job

The other half is recording it. In a care setting, an action that is not written down is, for inspection purposes, an action that did not happen. A repositioning chart captures the time, the new position, a skin check and the carer’s initials, every turn.

That record matters for two reasons. Clinically, it lets the next carer see when the person was last moved and how their skin looked, so nothing is missed across a shift change. And for the CQC, under Regulation 12 (safe care and treatment), the chart is the evidence that a person at risk was actually repositioned and monitored. Missing or patchy repositioning records are one of the most common pressure-ulcer findings in inspections.

Make it easy to do well

The reason charts get left blank is friction: they are hard to fill in, or kept somewhere awkward. A clear, simple chart that takes seconds to complete, kept with the person, is far more likely to be done honestly and consistently than a complicated form nobody has time for. The goal is a record that is both useful at the bedside and solid as evidence.
