Understanding Bed-Exit Alarms

Most hospital bed falls occur when a patient enters or exits the bed without staff assistance. Many fall risk patients forget to use the nurse call button and overestimate their physical abilities, which can lead to a fall or trip out of bed. Maintaining constant patient supervision to eliminate this unassisted movement can prove to be a costly effort for hospitals, as the cost of around the clock sitters adds up.

To combat the high cost of patient sitters, bed-exit alarms were introduced to detect bed activity and to minimize the number of bed exits without staff assistance. Instead of using a sitter to observe patient movement, the bed-exit alarm was designed to alert the nurses’ station to bed exit activity based on a change in patient positioning. A nurse’s response to the alarm would enable her to reposition, or assist the patient out of bed, which would minimize the possibility of a fall.

The use of a bed-exit alarm is recommended for use with patients with stability issues, on medication, with cognitive impairment, or with any patient identified as a fall risk. Bed-exit alarms can help prevent falls by alerting nurses to bed exit behaviour that is attributed to patient falls, and is recommended as an integral component of a hospital’s patient fall prevention program.
