A reason for overdose: the invisible patch

Disorientation and agitation are common in old patients  inside the hospital  and they are treated with  sedative and hypnotic very often. As a consequence a low level of consciousness is common in this population. But sometimes the reason  is more subtle. Many patients are treated with analgesic patches located in different subcutaneous areas. When they are located on the back they could be undetected and the patient will have a high probability for overdose.
