NICUs in the US: levels of acuity, number of beds, and relationships to population factors

Should neonatal-perinatal medicine move to two-year fellowships?

The duration of the majority of fellowships in pediatrics has been three-years. With increasing shortages of some outpatient-based pediatric subspecialists, shorter two-year fellowships are being considered for clinically oriented trainees not interested in a career based on research. Shortening the duration of fellowship may have some financial merits such as achieving a higher salary earlier after shorter training. However, we feel that continuing with a three-year duration for neonatology is more pragmatic at this time due to reductions in intensive care rotations during residency, time required to  achieve procedural excellence, the need for exposure to quality assurance methodology, proficiency in novel techniques such as bedside ultrasound, and to maintain the physician-scientist pipeline. The demand for neonatal fellowship continues to be high. Ongoing evaluation of the job market, training needs and fellowship curriculum is needed to determine if the duration of fellowship should be altered in the future.

Building a NICU quality & safety infrastructure

The American Academy of Pediatrics (AAP) Standards for Levels of Neonatal Care, published in 2023, highlights key components of a Neonatal Patient Safety and Quality Improvement Program (NPSQIP). A comprehensive Neonatal Intensive Care Unit (NICU) quality and safety infrastructure (QSI) is based on four foundational domains: quality improvement, quality assurance, safety culture, and clinical guidelines. This paper serves as an operational guide for NICU clinical leaders and quality champions to navigate these domains and develop their local QSI to include the AAP NPSQIP standards.

Neonatal Intensive Care Unit Resource Use for Infants at 22 Weeks' Gestation in the US, 2008-2021

Importance

During the past decade, clinical guidance about the provision of intensive care for infants born at 22 weeks' gestation has changed. The impact of these changes on neonatal intensive care unit (NICU) resource utilization is unknown.

Objective

To characterize recent trends in NICU resource utilization for infants born at 22 weeks' gestation compared with other extremely preterm infants (≤28 weeks' gestation) and other NICU-admitted infants.

Design, Setting, and Participants

This is a serial cross-sectional study of 137 continuously participating NICUs in 29 US states from January 1, 2008, through December 31, 2021. Participants included infants admitted to the NICU. Data analysis was performed from October 2022 to August 2023.

Exposures

Year and gestational age at birth.

Main Outcomes and Measures

Measures of resource utilization included NICU admissions, NICU bed-days, and ventilator-days.

Results

Of 825 112 infants admitted from 2008 to 2021, 60 944 were extremely preterm and 872 (466 [53.4%] male; 18 [2.1%] Asian; 318 [36.5%] Black non-Hispanic; 218 [25.0%] Hispanic; 232 [26.6%] White non-Hispanic; 86 [9.8%] other or unknown) were born at 22 weeks' gestation. NICU admissions at 22 weeks' gestation increased by 388%, from 5.7 per 1000 extremely preterm admissions in 2008 to 2009 to 27.8 per 1000 extremely preterm admissions in 2020 to 2021. The number of NICU admissions remained stable before the publication of updated clinical guidance in 2014 to 2016 and substantially increased thereafter. During the study period, bed-days for infants born at 22 weeks increased by 732%, from 2.5 per 1000 to 20.8 per 1000 extremely preterm NICU bed-days; ventilator-days increased by 946%, from 5.0 per 1000 to 52.3 per 1000 extremely preterm ventilator-days. The proportion of NICUs admitting infants born at 22 weeks increased from 22.6% to 45.3%. Increases in NICU resource utilization during the period were also observed for infants born at less than 22 and at 23 weeks but not for other gestational ages. In 2020 to 2021, infants born at less than or equal to 23 weeks' gestation comprised 1 in 117 NICU admissions, 1 in 34 of all NICU bed-days, and 1 in 6 of all ventilator-days.

Conclusions and Relevance

In this serial cross-sectional study of 137 US NICUs from 2008 to 2021, an increasing share of resources in US NICUs was allocated to infants born at 22 weeks' gestation, corresponding with changes in national clinical guidance.

Reimagining the NICU: a human-centered design approach to healthcare innovation

Design charettes have been utilized in architectural and design practice to generate innovative ideas. The Reimagining Workshop is a version that combines practical and blue-sky thinking to improve healthcare facility design. The workshop engages diverse stakeholders who follow a human-centered design framework. The Reimagining the Neonatal Intensive Care Unit workshop sought to generate ideas for the future, optimal NICU without specific site or client constraints. Key themes include family-centered care, technology-enabled care, neighborhood and village design and investing in the care team. Recommendations include a supportive physical environment, celebrating milestones, complementary and alternative medicine, enhancing the transition of care, aiding the transition period, and leveraging technology. The workshop showcased the potential for transformative change in NICU design and provided a roadmap for future advancements. These findings can inform regulatory standards for NICU design and drive improvements in family-centered care, patient experiences, and outcomes within the NICU environment.

Antibiotic Use Among Infants Admitted to Neonatal Intensive Care Units

This cross-sectional study examines antibiotic exposure, days of therapy, types of antibiotics, and changes in use patterns among newborns in neonatal intensive care units (NICUs) across the US from 2009 to 2021.

Hospital Variation in Mortality and Failure to Rescue after Surgery for High-Risk Neonatal Diagnoses

INTRODUCTION

A large proportion of postoperative mortality after pediatric surgery occurs among neonates with specific high-risk diagnoses. The extent to which there is hospital-level mortality variation among patients with these diagnoses and whether this variation is associated with differences in failure to rescue (FTR) is unclear.

METHODS

The Pediatric Health Information System® database (2012-2020) was used to identify patients who underwent surgery for eight high-risk neonatal diagnoses: gastroschisis; volvulus; necrotizing enterocolitis; intestinal atresia; meconium peritonitis; tracheoesophageal fistula; congenital diaphragmatic hernia; and perinatal intestinal perforation. Hospitals were stratified into tertiles of reliability-adjusted inpatient mortality rates (lower than average mortality - tertile 1 [T1]; higher than average mortality - tertile 3 [T3]). Multivariable hierarchical regression was used to evaluate the association between hospital-level, reliability-adjusted mortality and FTR.

RESULTS

Overall, 20,838 infants were identified across 48 academic, pediatric hospitals. Adjusted hospital mortality rates ranged from 4.0% (95% CI, 0.0-8.2) to 16.3% (12.2-20.4). Median case volume (range, 80-1,238) and number of NICU beds (range, 24-126) were not significantly different across hospital tertiles. Compared to the hospitals with the lowest postoperative mortality (T1), the odds of FTR were significantly higher in hospitals with the highest (T3) postoperative mortality (odds ratio 1.97 [1.50-2.59]).

CONCLUSIONS

Significant variation in neonatal hospital mortality for high-risk diagnoses does not appear to be explained by hospital structural characteristics. Rather, difference in FTR suggests quality improvement interventions targeting early recognition and management of postoperative complications could improve surgical quality and safety for high-risk neonatal care.
