BACKGROUND AND OBJECTIVES: Infants in NICUs are at risk for underimmunization. Adherence to the routine immunization schedule recommended by the Advisory Committee for Immunization Practices minimizes the risk of contracting vaccine-preventable illnesses in this vulnerable population. From January 2015 to June 2017, only 56% (419 of 754) of the infants in our Mayo Clinic level IV NICU were fully up to date for recommended immunizations at the time of discharge or hospital unit transfer. We aimed to increase this rate to 80% within 6 months. METHODS: Using the quality improvement methodology of Define, Measure, Analyze, Improve, Control, we analyzed baseline data, including provider and nursing surveys using a fishbone diagram, the 5 Whys, and a Pareto chart. We identified 3 major root causes of the quality gap: lack of provider knowledge of the routine immunization schedule, failure of providers to order vaccines when due, and hesitancy of parents toward vaccination. Using plan-do-study-act cycles, 5 improvement interventions were implemented. These included an intranet resource for NICU providers on the routine immunization schedule, an Excel-based checklist to track when immunizations were due, and provider education on parental vaccine hesitancy and vaccine safety. RESULTS: During the 19-month improve and control phases of the project, the fully immunized rate at the time of NICU discharge or transfer rose from a baseline of 56% (419 of 754) to 93% (453 of 488), with a P value CONCLUSIONS: Our NICU significantly improved infant immunization rates with a small number of interventions. These interventions may be generalizable to other NICUs with low infant immunization rates.

BACKGROUND AND OBJECTIVE: Previous studies suggest that former late preterm infants are at increased risk for learning and behavioral problems compared with term infants. These studies have primarily used referred clinical samples of children followed only until early school age. Our objective was to determine the cumulative incidence of attention deficit/hyperactivity disorder (ADHD) and learning disabilities (LD) in former late preterm versus term infants in a population-based birth cohort. METHODS: Subjects included all children born 1976 to 1982 in Rochester, MN who remained in the community after 5 years. This study focused on the comparison of subjects in 2 subgroups, late preterm (34 to RESULTS: We found no statistically significant differences in the cumulative incidence of ADHD or LD between the late preterm (N = 256) versus term (N = 4419) groups: ADHD (cumulative incidence by age 19 years, 7.7% vs 7.2%; P = .84); reading LD (14.2% vs 13.1%; P = .57); written language LD (13.5% vs 15.7%; P = .36), and math LD (16.1% vs 15.5%; P = .89). CONCLUSIONS: These data from a population-based birth cohort indicate that former late preterm infants have similar rates of LD and ADHD as term infants.

CONTEXT:The effectiveness of many interventions aimed at reducing the risk of retinopathy has not been well established.OBJECTIVE:To estimate the effectiveness of nutritional interventions, oxygen saturation targeting, blood transfusion management, and infection prevention on the incidence of retinopathy of prematurity (ROP).DATA SOURCES:A comprehensive search of several databases was conducted, including Medline, Embase, Cochrane Central Register of Controlled Trials, Cochrane Database of Systematic Reviews, and Scopus through March 2014.STUDY SELECTION:We included studies that evaluated nutritional interventions, management of supplemental oxygen, blood transfusions, or infection reduction and reported the incidence of ROP and mortality in neonates born at DATA EXTRACTION:We extracted patient characteristics, interventions, and risk of bias indicators. Outcomes of interest were any stage ROP, severe ROP or ROP requiring treatment, and mortality.RESULTS:We identified 67 studies enrolling 21 819 infants. Lower oxygen saturation targets reduced the risk of developing any stage ROP (relative risk [RR] 0.86, 95% confidence interval [CI], 0.77–0.97) and severe ROP or ROP requiring intervention (RR 0.58, 95% CI, 0.45–0.74) but increased mortality (RR 1.15, 95% CI, 1.04–1.29). Aggressive parenteral nutrition reduced the risk of any stage ROP but not severe ROP. Supplementation of vitamin A, E, or inositol and breast milk feeding were beneficial but only in observational studies. Use of transfusion guidelines, erythropoietin, and antifungal agents were not beneficial.LIMITATIONS:Results of observational studies were not replicated in randomized trials. Interventions were heterogeneous across studies.CONCLUSIONS:At the present time, there are no safe interventions supported with high quality evidence to prevent severe ROP.

For more than a decade there has been considerable interest in the role of QT interval prolongation in the pathogenesis of sudden infant death syndrome. It has been proposed that the QT interval is a surrogate marker for autonomic instability and can be used to identify infants at risk for significant morbidity and mortality, including sudden infant death syndrome. We present the case of an infant that experienced a significant increase in his QTc, as detected by continuous QTc monitoring in the NICU after repositioning from a supine to prone position. This increase from a 413 ± 6 millisecond baseline average to 500 milliseconds was sustained for 2 hours and associated with clinically relevant apnea that ultimately required repositioning of the infant back to the supine position. Repositioning resulted in an immediate decrease of the QTc back to the previous baseline and termination of the apneic events. This case demonstrates an example of how the use of continuous QTc monitoring in the NICU setting may be used to detect QTc-accentuating factors in real time and identify situations that cause perturbations in an infant’s autonomic nervous system.

In this report, we review the case of a candidal lens abscess in a premature infant girl who was 28 weeks’ gestational age at birth. The culture obtained from the lens abscess grew Candida albicans sensitive to amphotericin B but resistant to flucytosine. This case is unique in that the infant developed a fungal lens cataract at 34 weeks’ postconceptional age during the last week of a 30-day course of amphotericin B. The embryonic hyaloid artery system, which perfuses the developing lens, regresses between 29 and 32 weeks of gestation; thus, the mechanism for an infection of the lens may be inoculation of the lens by Candida before hyaloid artery system regression, followed by developmental loss of this blood supply, which makes the lens inaccessible to antimicrobial penetration. Candidal endophthalmitis with lens abscess is an uncommon morbidity that requires prompt recognition and surgical intervention for effective management.

Objective. This study was pursued as an extension of a randomized clinical investigation of neonatal screening for cystic fibrosis (CF). The project included assessment of respiratory secretion cultures for pathogens associated with CF. The objective was to determine whether patients diagnosed through neonatal screening and treated in early infancy were more likely to become colonized with Pseudomonas aeruginosa compared with those identified by standard diagnostic methods. Methodology. The design involved prospective cultures of respiratory secretions obtained generally by oropharyngeal swabs at least every 6 months and more often if clinically indicated. Patients were managed with a standardized evaluation and treatment protocol at the two Wisconsin certified CF centers; however, there were community and environmental variations associated with the follow-up period as described below. Results. Overall, there were no differences in acquisition of respiratory pathogens between the screened and the control (standard diagnosis) groups. Evaluation of the data between and within the two centers, however, revealed significant differences with earlier acquisition of P aeruginosa in the center with the following distinguishing characteristics: urban location; following patients with the standard US approach in which newly diagnosed, young children were interspersed with older CF patients; and where there were more opportunities for social interactions with other CF patients. The differences were confined to the screened group followed in the urban center in which the median pseudomonas-free survival period was 52 weeks contrasted with 289 weeks in the other center. In addition, assessment of data for the entire CF populations followed at the two centers revealed that the urban center showed a significantly higher prevalence of P aeruginosa colonization in patients between the ages of 3 and 9 years. Conclusions. These results present questions and generate hypotheses on risk factors for acquisition of P aeruginosain CF and suggest that clinic exposures and/or social interactions may predispose such patients to pseudomonas infections.
