A hand-held scanner appliance is employed to capture and display status of various types of catheter devices that have been inserted in hospital patients. The nurse scans his or her staff ID coded device, then scans the patient's ID wrist bracelets, and scans a catheter-unique identification coded tag on the catheter device. When the nurse performs a catheter insertion, and the catheter is scanned, a data entry is recorded with the patient identity, presence of catheter, and time of insertion. An intelligent rules engine computes the target removal time for the catheter device, which is also displayed. An alert for each catheterization occurs prior to the target removal time. The appliance is synchronized to the hospital server, and the catheterization status of the hospital patients is displayed for the medical practitioner. This process aids in preventing hospital-acquired infections.
