Elevation devices for the prevention of heel pressure ulcers: a review.
OBJECTIVE
The objective of this systematic literature review was to gain insight into the effectiveness of off-loading devices to prevent heel pressure ulcers within the acute hospital setting.


BACKGROUND
Heels have been identified as the second most common site for pressure ulcers. Devices which off-load pressure can include pillows, wedges and boots. It is unclear as to which method or device is best at preventing pressure ulcers.


METHODS
A systematic review was carried out through the search of electronic databases and bibliographies of relevant publications. Randomised controlled trials (RCTs) and systematic reviews that compared devices which off-load heels to prevent pressure ulcers were identified.


RESULTS
A total of five studies were included in the review. The methodological quality of the studies was generally poor. The studies reported that heel-boot elevation devices appeared more beneficial. However, poor compliance with wearing the devices was identified, as well as a perceived increased risk of falls. There were little data on cost-effectiveness.


CONCLUSIONS
There is little high-quality trial evidence to support the routine use of heel devices to prevent pressure ulcers. However, they may have a role to play within a multifaceted programme of pressure-ulcer prevention.
