The Resource Use Inflection Point for Safe NICU Discharge.

Area of Science:

• Neonatalogy
• Health Services Research
• Healthcare Economics

Background:

• Neonatal Intensive Care Units (NICUs) provide critical care for vulnerable infants.
• Determining the optimal time for NICU discharge is crucial for resource allocation and cost-efficiency.
• Significant variability exists in NICU length of stay and associated healthcare expenditures.

Purpose of the Study:

• To define a resource use inflection point (RU-IP) indicating when NICU patients no longer require intensive care.
• To quantify inter-hospital variability in patient days beyond the RU-IP.
• To identify risk factors associated with reaching an RU-IP.

Main Methods:

• Evaluation of 80,821 neonates admitted to 43 NICUs over six years.
• Definition of RU-IP based on daily standardized cost falling below 10% of the mean first-day NICU cost and remaining so until discharge.
• Comparison of patient days, costs, and proportions of patients reaching RU-IP across hospitals.

Main Results:

• 80.6% of neonates reached an RU-IP, accounting for 24.3% of total NICU days and over $483 million in costs.
• Significant variability observed in the proportion of patients reaching RU-IP (33.1% to 98.7%) across hospitals.
• Factors like extreme prematurity, home health care, mechanical ventilation, ECMO, and feeding support were associated with fewer days beyond RU-IP, while methadone use increased these days.

Conclusions:

• Identifying an RU-IP can facilitate earlier discharge readiness, leading to substantial savings in NICU days and healthcare costs.
• The study highlights the need to identify and disseminate best practices for efficient infant discharge from NICUs.
• Implementing quality improvement projects based on these best practices can enhance care predictability and safety for all neonates.
