Physical space of thirty pediatric intensive care units in the United States of America: a national survey.

Introduction: The design of Pediatric Intensive Care Unit (PICU) rooms significantly impacts patient care and satisfaction. The aims were first, to describe the current physical space across PICUs in the USA, and second, to identify what proportion of PICUs are compliant with current guidelines. Methods: A descriptive cross-sectional survey was conducted, targeting division chiefs and medical directors of PICUs nationwide. The survey collected data on unit type, construction and renovation dates, room sizes, and available amenities. According to the Guidelines for Design and Construction of Hospitals, PICU rooms are recommended to be single rooms, at least 200 sq ft, have a window and a private bathroom. Data were anonymized and reported as median and interquartile ranges or frequencies and percentages. Results: Thirty units responded. Among the respondents, 26 had general PICUs, 9 had cardiac ICUs, and 3 had intermediate care units, with some units containing multiple types of ICUs. The median annual admissions were 1,125, with a median occupancy rate of 78%. Twenty-three percent of units had at least one double room, and 3% had triple or quadruple rooms. The median room size was 265 sq ft (IQR 230; 304), the smallest room size was 220 sq ft (IQR 179; 275), and the largest single room size was 312 sq ft (IQR 273; 330). Thirty-seven percent of units had bathrooms in every room, while 80% had windows in every room. Additionally, 46% of units had dialysis capabilities in every room, and 7% had negative pressure capabilities in every room. The median building year was 2008 (IQR 2001;2014), with 36% of units having undergone at least one renovation. Larger rooms were associated with more recent build dates (p = 0.01). Only 30% of the PICUs met the guidelines for physical space. These compliant units were built at a median of 4 years ago (IQR 1; 8). Conclusion: This study highlights the variability in PICU room design and amenities across healthcare facilities. Many units still fall short of meeting the guidelines for room size, windows, and private bathrooms. Future research should investigate the relationship between room characteristics and patient outcomes to inform better design practices, with a goal of improving patient experiences and clinical outcomes.

Measuring practice preference variation for quality improvement in neonatal respiratory care.

OBJECTIVES: The authors sought to measure and compare practice preference variation in neonatal respiratory care within and between neonatal intensive care units (NICUs) using the Neonatology Survey of Interdisciplinary Groups in Healthcare Tool (NSIGHT). STUDY DESIGN: Eleven NICUs completed the NSIGHT between 2019 and 2021. Net preference was measured by mean response; agreement was ranked by standard distribution of response values. Heat maps showed comparisons between NICUs and disciplines. RESULTS: NICUs and individuals agreed most often on use of pressure support with mandatory ventilation and on use of non-invasive positive pressure ventilation for apnea. High preference variation surrounded decisions for invasive ventilation versus continuous positive airway pressure for extremely low birth weight infants. Preference difference was most frequent between neonatologists and nurses. CONCLUSIONS: Patterns of practice preference variation in neonatal respiratory care are specific to clinical scenario. Measuring preference variation may inform psychology of change and strengthen quality improvement efforts.

Reducing MRSA Infection in a New NICU During the COVID-19 Pandemic.

BACKGROUND AND OBJECTIVES: Methicillin-resistant Staphylococcus aureus (MRSA) is prevalent in most NICUs, with a high rate of skin colonization and subsequent invasive infections among hospitalized neonates. The effectiveness of interventions designed to reduce MRSA infection in the NICU during the coronavirus disease 2019 (COVID-19) pandemic has not been characterized. METHODS: Using the Institute for Healthcare Improvement's Model for Improvement, we implemented several process-based infection prevention strategies to reduce invasive MRSA infections at our level IV NICU over 24 months. The outcome measure of invasive MRSA infections was tracked monthly utilizing control charts. Process measures focused on environmental disinfection and hospital personnel hygiene were also tracked monthly. The COVID-19 pandemic was an unexpected variable during the implementation of our project. The pandemic led to restricted visitation and heightened staff awareness of the importance of hand hygiene and proper use of personal protective equipment, as well as supply chain shortages, which may have influenced our outcome measure. RESULTS: Invasive MRSA infections were reduced from 0.131 to 0 per 1000 patient days during the initiative. This positive shift was sustained for 30 months, along with a delayed decrease in MRSA colonization rates. Several policy and practice changes regarding personnel hygiene and environmental cleaning likely contributed to this reduction. CONCLUSIONS: Implementation of a multidisciplinary quality improvement initiative aimed at infection prevention strategies led to a significant decrease in invasive MRSA infections in the setting of the COVID-19 pandemic.

D-bifunctional protein deficiency caused by splicing variants in a neonate with severe peroxisomal dysfunction and persistent hypoglycemia.

D-bifunctional protein (DBP) deficiency is a rare, autosomal recessive peroxisomal enzyme deficiency resulting in a high burden of morbidity and early mortality. Patients with DBP deficiency resemble those with a severe Zellweger phenotype, with neonatal hypotonia, seizures, craniofacial dysmorphisms, psychomotor delay, deafness, blindness, and death typically within the first 2 years of life, although patients with residual enzyme function can survive longer. The clinical severity of the disease depends on the degree of enzyme deficiency. Loss-of-function variants typically result in no residual enzyme activity; however, splice variants may result in protein with residual function. We describe a full-term newborn presenting with hypotonia, seizures, and unexplained hypoglycemia, who was later found to have rickets at follow up. Rapid whole genome sequencing identified two HSD17B4 variants in trans; one likely pathogenic variant and one variant of uncertain significance (VUS) located in the polypyrimidine tract of intron 13. To determine the functional consequence of the VUS, we analyzed RNA from the patient's father with RNA-seq which showed skipping of Exon 14, resulting in a frameshift mutation three amino acids from the new reading frame. This RNA-seq analysis was correlated with virtually absent enzyme activity, elevated very-long-chain fatty acids in fibroblasts, and a clinically severe phenotype. Both variants are reclassified as pathogenic. Due to the clinical spectrum of DBP deficiency, this provides important prognostic information, including early mortality. Furthermore, we add persistent hypoglycemia to the clinical spectrum of the disease, and advocate for the early management of fat-soluble vitamin deficiencies to reduce complications.

A novel and accurate method for estimating umbilical arterial and venous catheter insertion length.

OBJECTIVE: To develop a novel, rapid, and more accurate model for estimating umbilical arterial (UAC) and venous catheter (UVC) insertion length. STUDY DESIGN: We evaluated UACs and UVCs from a retrospective cohort to determine the rate of correct initial positioning based on conventional birth weight-based equations utilized in our neonatal intensive care unit. We then derived new equations, developed the mobile application, UmbiCalc, to simplify implementation of the new equations, and validated their accuracy with prospective utilization. RESULTS: The conventional equations successfully predicted insertion length in 69% (364 of 524) of UACs and only 36% (194 of 544) of UVCs. Our new model was prospectively applied to 68 UAC and 80 UVC placements with successful initial positioning achieved in 90% [95% CI, 80.2-94.9] and 76% [95% CI, 65.9-84.2], respectively. CONCLUSIONS: Our novel approach more accurately estimates UAC and UVC insertion length.

An Initiative to Decrease Laboratory Testing in a NICU.

BACKGROUND AND OBJECTIVES: Laboratory testing is performed frequently in the NICU. Unnecessary tests can result in increased costs, blood loss, and pain, which can increase the risk of long-term growth and neurodevelopmental impairment. Our aim was to decrease routine screening laboratory testing in all infants admitted to our NICU by 20% over a 24-month period. METHODS: We designed and implemented a multifaceted quality improvement project using the Institute for Healthcare Improvement's Model for Improvement. Baseline data were reviewed and analyzed to prioritize order of interventions. The primary outcome measure was number of laboratory tests performed per 1000 patient days. Secondary outcome measures included number of blood glucose and serum bilirubin tests per 1000 patient days, blood volume removed per 1000 patient days, and cost. Extreme laboratory values were tracked and reviewed as balancing measures. Statistical process control charts were used to track measures over time. RESULTS: Over a 24-month period, we achieved a 26.8% decrease in laboratory tests performed per 1000 patient days (∽51 000 fewer tests). We observed significant decreases in all secondary measures, including a decrease of almost 8 L of blood drawn and a savings of $258 000. No extreme laboratory values were deemed attributable to the interventions. Improvement was sustained for an additional 7 months. CONCLUSIONS: Targeted interventions, including guideline development, dashboard creation and distribution, electronic medical record optimization, and expansion of noninvasive and point-of-care testing resulted in a significant and sustained reduction in laboratory testing without notable adverse effects.

Gastrointestinal Zygomycosis in a Preterm Neonate Associated With Contaminated Probiotics.

A neonate of 29 weeks' gestation who received probiotics developed clinical signs suggesting surgical necrotizing enterocolitis. A specimen of resected ileum revealed fungal forms within the bowel wall. Rhizopus oryzae was detected via DNA sequencing from probiotic powder and tissue specimens from the infant. To our knowledge, this is the first report linking gastrointestinal zygomycosis to the administration of contaminated probiotics.

Evaluating the effect of hospital setting on outcomes for neonatal abstinence syndrome.

OBJECTIVES: This study aims to evaluate the impact of hospital setting on outcomes for infants with neonatal abstinence syndrome. STUDY DESIGN: We conducted a retrospective study in two hospitals and three different hospital units. The inpatient group (n = 60) was managed on general inpatient floors, the NICU group (n = 50) was managed primarily in an NICU, and the combination group (n = 49) was managed in both NICU and inpatient units. The primary outcome was length of stay. Secondary outcomes included breastfeeding rates, morphine usage rates, and hospital costs. RESULTS: The length of stay in the inpatient group (8.5 days) was significantly lower than the combination group (18 days) and NICU group (23 days) (p < 0.01). The inpatient group had significantly lower rates of morphine treatment and hospital costs with no difference in breastfeeding rates. CONCLUSIONS: Infants with neonatal abstinence syndrome had a significantly shorter length of stay and less use of morphine when managed on inpatient units versus NICU.
