Medical Information Bus usage for automated IV pump data acquisition: evaluation of usage patterns

Area of Science:

• Nursing Informatics
• Clinical Engineering
• Health Information Technology

Background:

• Automated data collection systems aim to improve efficiency and accuracy in healthcare settings.
• The Medical Information Bus (MIB) is a prototype system designed for integrating medical devices like IV pumps with hospital information systems.
• Understanding nurse adoption factors is crucial for successful implementation of new health technologies.

Purpose of the Study:

• To determine the factors influencing nurses' adoption of automated intravenous (IV) pump data collection.
• To evaluate the use of a prototype Medical Information Bus (MIB) for real-time IV pump data acquisition.

Main Methods:

• An observational study conducted over 3.5 months in four adult intensive care units.
• Data collected included infusion orders, medication types, rate changes, and documentation methods (automated via MIB vs. manual).
• 158 registered nurses participated, with 22,199 documented infusion rate changes analyzed.

Main Results:

• Over 99% (22,055 of 22,199) of infusion rate changes were documented using the automated MIB system.
• Medications requiring the most frequent rate adjustments included Nitroprusside Sodium, Epinephrine, and Epoprostenol.
• The automated method was predominantly chosen over manual documentation.

Conclusions:

• Nurses favored automated IV pump data acquisition, particularly for medications necessitating frequent rate modifications.
• The prototype MIB system demonstrated high adoption rates among nurses in intensive care settings.
• Automated data capture streamlines the management of complex infusions.
