Time-Motion Analysis of Nurses Utilizing Insulin Pen Devices Compared to Vial and Syringe in an Inpatient Setting.

Objective: To compare the time taken and steps completed by nurses in the process of insulin preparation and administration using the pen device compared to the vial and syringe method.

Methods: Observational and exploratory study utilizing a time-motion analysis of nurses' administration of insulin using the pen versus vial and syringe delivery methods. Nurses were observed, video-recorded, and timed during insulin preparation and administration using each delivery method.
