Optimizing Utilization of Laboratory Investigations in Neonatal Intensive Care Unit

Area of Science:

• Neonatal Medicine
• Healthcare Quality Improvement
• Clinical Laboratory Utilization

Background:

• Optimizing laboratory test utilization in neonatal intensive care units (NICUs) is crucial for cost-effectiveness and patient care.
• Baseline assessment of test rates and appropriateness is essential for identifying areas of improvement.
• Barriers to rational laboratory test ordering in resident doctors need to be understood and addressed.

Purpose of the Study:

• To optimize laboratory test utilization in a NICU setting.
• To measure baseline rates and appropriateness of laboratory investigations.
• To assess barriers to rational test use and implement an educational intervention for resident doctors.

Main Methods:

• A quality improvement study was conducted in a NICU from August 2015 to December 2016.
• Participants included neonates and resident doctors in the NICU.
• Interventions involved addressing barriers, an educational package, posters, and group discussions.

Main Results:

• Baseline laboratory test rates were 0.6 tests/patient/day, with one-fifth deemed inappropriate.
• Mechanical ventilation and sepsis predicted test rates but explained only 35% of variations, highlighting practice differences.
• Following the intervention, hematology test rates showed a reduction trend, but overall rates did not significantly change.

Conclusions:

• Educational interventions and awareness campaigns can decrease hematology laboratory test rates in the short term.
• Sustained interventions over a longer period are necessary to achieve significant changes in test ordering behavior.
• Addressing barriers and providing targeted education are key strategies for improving laboratory test utilization in NICUs.
