Table 4 Reasons for excluding assets from the real-time tracking

Patient tracking

Little need for tracking at the site (e.g., psychiatric patients, neonates)

Laryngoscopy handle

Reduces the usability of intubation devices (i.e., it is difficult to affix the tag because it could hinder visibility)

Difficulty in managing intubation devices (e.g., disinfection following each use)

Sandbag and ice pack

While necessary, the return on investment is low (i.e., the tag cost is high relative to the unit cost for these items)

Operating room items

The mobility of expensive medical instruments in the operating room is markedly low, so there is little need for tracking

Wheelchairs

While necessary, they were excluded because they are not for indoor use only (e.g., they are used outdoors frequently at medical institutions)
