Apparatus for intravascular access device displacement detection, where an intravascular access device is inserted into a blood vessel through the skin at an access site. The apparatus comprises electrodes located on either side of the intravascular access device which electrodes are mobile with the intravascular access device and attachable to the skin about the access site. The electrodes have a micro-current flow therebetween, which is sufficient to induce a current through the skin between the electrodes and the current persists as long as the electrodes are connected. If the device moves then one or more of the electrodes are disconnected and the micro-current is interrupted. A displacement alert device issues an alert signal upon interruption of the micro-current.
