We are investiagating PPID systems for housewide use with Pharm, Lab and BB. During one of our discussion meeting, the topic of band removal and rebanding came up. Occasionally, bands get too tight or they are in the way. The identification at admission requires photo ids and other checks. My concern is for the other areas of the hospital when verification is less likely to be as effective such as a sedated patient in surgery. In theory, this could ruin the integrity that the PPID system is trying to achieve. The concept of iris scanning is far better that some of the suggestions we formed on the walk to the lab from that meeting. Humans find the best ways around mechanical fixes.
