A patient monitoring system adapted for use with a bathroom. The system includes a motion detection unit including a motion detection sensor and a first housing. The system also includes an alarm unit having an alarm device and a second housing. Control circuitry operably couples the motion detection sensor with the alarm device. The control circuitry is configured to activate the alarm device when the motion detection sensor detects motion. The system also includes a support structure removably mounted on the bathroom door wherein the support structure is adapted to support the first housing proximate the interior surface of the door and support the second housing proximate the exterior surface of the door. The motion detection sensor is positioned so that when a fall-risk patient begins to rise from the toilet, the alarm device will alert a caregiver outside the bathroom who may then assist the patient.
