Preventing provider errors: online total parenteral nutrition calculator.

Area of Science:

• Medical Informatics
• Health Systems Engineering
• Neonatal Care

Background:

• Ordering total parenteral nutrition (TPN) in neonatal intensive care units (NICUs) is complex and prone to errors.
• Existing paper-based systems present challenges in accuracy and efficiency.
• Minimizing medical errors in TPN ordering is critical for patient safety in NICUs.

Purpose of the Study:

• To develop and evaluate a pragmatic, low-cost medical information system for TPN ordering.
• To reduce the incidence of medical errors associated with TPN orders in a NICU setting.
• To assess the impact of the system on error rates and user satisfaction.

Main Methods:

• An online TPN order entry system (TPNCalculator) was developed using internet technologies.
• The system's utilization, impact on medical errors, and user satisfaction were evaluated.
• Data were collected before implementation, immediately after (intervention 1), and after two years (intervention 2).

Main Results:

• The TPNCalculator system development took only three weeks.
• TPN order errors decreased from 10.8 per 100 orders to 1.2 per 100 orders (an 89% reduction) after two years.
• Significant reductions were observed in calculation errors (100%), osmolality issues (91%), and knowledge-based problems (100%), with initial challenges in form completeness resolved.

Conclusions:

• Low-cost, pragmatic medical information systems utilizing internet technology can effectively reduce medical errors.
• This approach offers a viable strategy for preventing adverse drug events in critical care settings.
• The TPNCalculator demonstrates the potential of accessible technology to improve patient safety in neonatal care.
