A valuable opportunity for reducing the fall incidence in hospitals, is alerting nurses when a patient
is about to fall. For such a fall prevention system, more knowledge is needed on what occurs right
before a fall. This can be achieved with a stereo camera that automatically detects (and records)
dangerous situations.
Inpatients with a high risk of falling are selected for inclusion. A fall-risk questionnaire is
administered and falls are logged during their stay. A stereo-camera (3D BRAVO-EagleEye
system) is mounted in the ceiling and monitors the bed with surroundings. A baseline recording is
made to improve the algorithms behind the alert system. When a fall or dangerous situation is
detected, monitoring data preceding the incident is stored. Data is analyzed to assess 1) the
quality of the system and 2) the prevalence of dangerous situations. Interviews with senior nurses
are included in the evaluation.
Data collection is ongoing (Currently n=18; falls=1), and currently consists of ±62 hour of baseline
recordings and ±24 hour of event-based recordings. These recordings include false positives as
well as actual high risk situations.
Despite the initial enthusiasm of the participating departments, inclusion of participants is slow,
and the number of falls lower than expected. Possible explanations for this have been discussed
with the involved senior nurses. With the monitoring data we gained more insight into the
occurrence of dangerous situations, but to be able to reliably predict falls, more data on actual falls
should be recorded.
