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.
