Reducing Unplanned Intubations in the Neonatal Intensive Care Unit After Children's Surgery: A Quality Improvement Project.

BACKGROUND: Unplanned intubation following children's surgery is associated with increased postoperative mortality. In response to being a National Surgical Quality Improvement Program - Pediatric (NSQIP-P) high outlier for postoperative unplanned intubation, we aimed to reduce postoperative unplanned intubation events by 25% in one year. METHODS/INTERVENTION: A multidisciplinary team of stakeholders was assembled in 2018. Most unplanned intubation events occurred in the neonatal intensive care unit (NICU). Based on apparent causes of unplanned intubations identified in case reviews, an extubation readiness checklist and a postoperative pain management guideline emphasizing non-opioid analgesics were implemented for NICU patients in September 2019. Postoperative unplanned intubation events were tracked prospectively and evaluated using quality improvement statistical process control methods. RESULTS: Unplanned intubations in the NICU decreased from 0.27 to 0.07 events per patient in the post-intervention group (September 2019-June 2022, n = 145) compared to the pre-intervention group (January 2016-August 2019, n = 200), representing a 76% reduction. Postoperative opioid administration decreased significantly, while acetaminophen usage increased significantly over time. Balancing measures of postoperative pneumonia rate (1.5% vs 0.0%, p = 0.267) and median hospital length of stay [40 (IQR 51) days vs 27 (IQR 60), p = 0.124] were not different between cohorts. The 30-day mortality rate for postoperative patients in the NICU significantly declined [6.5% (n = 13) vs 0.7% (n = 1), p < 0.001]. CONCLUSIONS: Postoperative unplanned intubation rates for NICU patients decreased following a quality improvement effort focused on opioid stewardship and extubation readiness. TYPE OF STUDY: Prospective Quality Improvement. LEVEL OF EVIDENCE: Level III.

Measuring Childbirth Outcomes Using Administrative and Birth Certificate Data.

BACKGROUND: The number of pregnancy-related deaths and severe maternal complications continues to rise in the United States, and the quality of obstetrical care across U.S. hospitals is uneven. Providing hospitals with performance feedback may help reduce the rates of severe complications in mothers and their newborns. The aim of this study was to develop a risk-adjusted composite measure of severe maternal morbidity and severe newborn morbidity based on administrative and birth certificate data. METHODS: This study was conducted using linked administrative data and birth certificate data from California. Hierarchical logistic regression prediction models for severe maternal morbidity and severe newborn morbidity were developed using 2011 data and validated using 2012 data. The composite metric was calculated using the geometric mean of the risk-standardized rates of severe maternal morbidity and severe newborn morbidity. RESULTS: The study was based on 883,121 obstetric deliveries in 2011 and 2012. The rates of severe maternal morbidity and severe newborn morbidity were 1.53% and 3.67%, respectively. Both the severe maternal morbidity model and the severe newborn models exhibited acceptable levels of discrimination and calibration. Hospital risk-adjusted rates of severe maternal morbidity were poorly correlated with hospital rates of severe newborn morbidity (intraclass correlation coefficient, 0.016). Hospital rankings based on the composite measure exhibited moderate levels of agreement with hospital rankings based either on the maternal measure or the newborn measure (κ statistic 0.49 and 0.60, respectively.) However, 10% of hospitals classified as average using the composite measure had below-average maternal outcomes, and 20% of hospitals classified as average using the composite measure had below-average newborn outcomes. CONCLUSIONS: Maternal and newborn outcomes should be jointly reported because hospital rates of maternal morbidity and newborn morbidity are poorly correlated. This can be done using a childbirth composite measure alongside separate measures of maternal and newborn outcomes.

A randomized controlled trial: does coaching using video during direct laryngoscopy improve residents' success in neonatal intubations?

OBJECTIVE: To evaluate the intubation success rates of residents who receive coaching from supervisors concurrently viewing infants' airways via video during direct laryngoscopy (VDL), as compared with coaching during traditional direct laryngoscopy without video (TDL). STUDY DESIGN: In a randomized controlled trial, 48 first and second-year residents performed neonatal intubations using VDL or TDL. The primary outcome was intubation success rates. Data were analyzed using the Pearson X2 and Student's t-test. RESULTS: The overall intubation success rate was greater in the VDL vs. TDL group (57% vs. 33%, P < 0.05). First-year residents and residents intubating their first patient had higher intubation success rates in the VDL vs. TDL group (58% vs. 23% and 50% vs. 17%, respectively, P < 0.05). CONCLUSIONS: Resident coaching using VDL improved neonatal intubation success rates. Incorporating VDL as a coaching tool can optimize the quality of training during limited opportunities to achieve procedural competency and improve intubation-related patient outcomes.

Statewide Initiative to Reduce Postnatal Growth Restriction among Infants <31 Weeks of Gestation.

OBJECTIVE: To decrease the incidence of postnatal growth restriction, defined as discharge weight <10th percentile for postmenstrual age, among preterm infants cared for in New York State Regional Perinatal Centers. STUDY DESIGN: The quality improvement cohort consisted of infants <31 weeks of gestation admitted to a New York State Regional Perinatal Center within 48 hours of birth who survived to hospital discharge. Using quality improvement principles from the Institute for Healthcare Improvement and experience derived from successfully reducing central line-associated blood stream infections statewide, the New York State Perinatal Quality Collaborative sought to improve neonatal growth by adopting better nutritional practices identified through literature review and collaborative learning. New York State Regional Perinatal Center neonatologists were surveyed to characterize practice changes during the project. The primary outcome-the incidence of postnatal growth restriction-was compared across the study period from baseline (2010) to the final (2013) years of the project. Secondary outcomes included differences in z-score between birth and discharge weights and head circumferences. RESULTS: We achieved a 19% reduction, from 32.6% to 26.3%, in postnatal growth restriction before hospital discharge. Reductions in the difference in z-score between birth and discharge weights were significant, and differences in z-score between birth and discharge head circumference approached significance. In survey data, regional perinatal center neonatologists targeted change in initiation of feedings, earlier breast milk fortification, and evaluation of feeding tolerance. CONCLUSIONS: Statewide collaborative quality improvement can achieve significant improvement in neonatal growth outcomes that, in other studies, have been associated with improved neurodevelopment in later infancy.

Bronchopulmonary Dysplasia and Perinatal Characteristics Predict 1-Year Respiratory Outcomes in Newborns Born at Extremely Low Gestational Age: A Prospective Cohort Study.

OBJECTIVE: To assess the utility of clinical predictors of persistent respiratory morbidity in extremely low gestational age newborns (ELGANs). STUDY DESIGN: We enrolled ELGANs (<29 weeks' gestation) at ≤7 postnatal days and collected antenatal and neonatal clinical data through 36 weeks' postmenstrual age. We surveyed caregivers at 3, 6, 9, and 12 months' corrected age to identify postdischarge respiratory morbidity, defined as hospitalization, home support (oxygen, tracheostomy, ventilation), medications, or symptoms (cough/wheeze). Infants were classified as having postprematurity respiratory disease (PRD, the primary study outcome) if respiratory morbidity persisted over ≥2 questionnaires. Infants were classified with severe respiratory morbidity if there were multiple hospitalizations, exposure to systemic steroids or pulmonary vasodilators, home oxygen after 3 months or mechanical ventilation, or symptoms despite inhaled corticosteroids. Mixed-effects models generated with data available at 1 day (perinatal) and 36 weeks' postmenstrual age were assessed for predictive accuracy. RESULTS: Of 724 infants (918 ± 234 g, 26.7 ± 1.4 weeks' gestational age) classified for the primary outcome, 68.6% had PRD; 245 of 704 (34.8%) were classified as severe. Male sex, intrauterine growth restriction, maternal smoking, race/ethnicity, intubation at birth, and public insurance were retained in perinatal and 36-week models for both PRD and respiratory morbidity severity. The perinatal model accurately predicted PRD (c-statistic 0.858). Neither the 36-week model nor the addition of bronchopulmonary dysplasia to the perinatal model improved accuracy (0.856, 0.860); c-statistic for BPD alone was 0.907. CONCLUSION: Both bronchopulmonary dysplasia and perinatal clinical data accurately identify ELGANs at risk for persistent and severe respiratory morbidity at 1 year. TRIAL REGISTRATION: ClinicalTrials.gov: NCT01435187.

Variation in Enteral Feeding Practices and Growth Outcomes among Very Premature Infants: A Report from the New York State Perinatal Quality Collaborative.

BACKGROUND: Extrauterine growth restriction (EUGR) is inversely related to neurodevelopmental outcome. We analyzed growth outcomes and enteral nutrition practices among preterm infants at New York State (NYS) regional perinatal centers (RPCs) to identify practices associated with risk of EUGR. METHODS: Surviving infants < 31 weeks' gestation admitted to a NYS RPC during 2010 were identified and data collected on their growth and enteral nutrition from a statewide database. Neonatologists at NYS RPCs were surveyed to identify center-specific nutritional practices. Survey responses, nutrition, and growth data were then analyzed to identify factors associated with risk of EUGR. RESULTS: Of the 1,387 infants, 32.6% were discharged with EUGR. Incidence of EUGR varied more than fivefold among RPCs. Nutritional practices directly related to EUGR included age at first enteral feeding and full enteral feedings. Among the surveyed nutrition practices, longer duration of trophic feeding before advancing was associated with an increased risk of EUGR while later discontinuation of total parenteral nutrition and larger trophic feeding volume were associated with lower risk. CONCLUSION: Our study found marked variation in nutrition practices and incidence of EUGR among preterm infants at NYS RPCs. A statewide quality improvement initiative to reduce practice variation and improve growth in preterm infants is underway.

Impact of the 2008 Beijing Olympics on the risk of pregnancy complications.

Taking advantage of the natural experiment of the 2008 Beijing Olympics (August 8 to September 24), when air pollution levels decreased by 13% to 60%, the authors assessed whether having ≥1 pregnancy month during the Olympics was associated with decreased risks of hypertensive disorders (HDs) and/or fetal-placental conditions (FPCs). Singleton births to mothers with ≥1 pregnancy month in 2008 or 2009 (N = 56,155) were included. Using generalized additive models, the authors estimated the risk of HDs and FPCs associated with (1) the 2008 Olympics compared with the same dates in 2009, and (2) increased mean ambient PM10 (particulate matter with an aerodynamic diameter <10 µm), NO2 (nitrogen dioxide), and SO2 (sulfur dioxide) concentrations during each trimester. However, no association between HDs or FPCs and having any trimester during the 2008 Olympic period was found. This may, in part, be due to a small number of pregnancy complications in this population.

Comparison of animal-derived surfactants for the prevention and treatment of respiratory distress syndrome in preterm infants.

BACKGROUND: Animal-derived surfactants have been shown to have several advantages over the first generation synthetic surfactants and are the most commonly used surfactant preparations. The animal-derived surfactants in clinical use are minced or lavaged and modified or purified from bovine or porcine lungs. It is unclear whether significant differences in clinical outcome exist among the available bovine (modified minced or lavage) and porcine (minced or lavage) surfactant extracts. OBJECTIVES: To compare the effect of administration of different animal-derived surfactant extracts on the risk of mortality, chronic lung disease, and other morbidities associated with prematurity in preterm infants at risk for or having respiratory distress syndrome (RDS). SEARCH METHODS: We used the standard search strategy of the Cochrane Neonatal Review group to search the Cochrane Central Register of Controlled Trials (CENTRAL 2015, Issue 7), MEDLINE via PubMed (1966 to July 31, 2015), EMBASE (1980 to July 31, 2015), and CINAHL (1982 to July 31, 2015). We also searched clinical trials databases, conference proceedings, and the reference lists of retrieved articles for randomized controlled trials and quasi-randomized trials. SELECTION CRITERIA: Randomized or quasi-randomized controlled trials that compared the effect of animal-derived surfactant extract treatment administered to preterm infants at risk for or having RDS to prevent complications of prematurity and mortality. DATA COLLECTION AND ANALYSIS: Data regarding clinical outcomes were excerpted from the reports of the clinical trials by the review authors. Subgroup analyses were performed based on gestational age, surfactant dosing and schedule, treatment severity and treatment strategy. Data analysis was performed in accordance with the standards of the Cochrane Neonatal Review Group. MAIN RESULTS: Sixteen randomized controlled trials were included in the analysis. Bovine lung lavage surfactant extract to modified bovine minced lung surfactant extract: Seven treatment studies and two prevention studies compared bovine lung lavage surfactant extract to modified bovine minced lung surfactant extract. The meta-analysis did not demonstrate any significant differences in death or chronic lung disease in the prevention trials (typical RR 1.02, 95% CI 0.89 to 1.17; typical RD 0.01, 95% CI -0.05 to 0.06; 2 studies and 1123 infants; high quality evidence) or treatment trials (typical RR 0.95, 95% CI 0.86 to 1.06; typical RD -0.02 , 95% CI -0.06 to 0.02; 3 studies and 2009 infants; high quality evidence) Modified bovine minced lung surfactant extract compared with porcine minced lung surfactant extract: Nine treatment studies compared modified bovine minced lung surfactant extract to porcine minced lung surfactant extract. Meta-analysis of these trials demonstrate a significant increase in the risk of mortality prior to hospital discharge (typical RR 1.44, 95% CI 1.04 to 2.00; typical RD 0.05, 95% CI 0.01 to 0.10; NNTH 20, 95% CI 10 to 100; 9 studies and 901 infants; moderate quality evidence), death or oxygen requirement at 36 weeks' postmenstrual age (typical RR 1.30, 95% CI 1.04 to 1.64; typical RD 0.11, 95% CI 0.02 to 0.20; NNTH 9, 95% CI 5 to 50; 3 studies and 448 infants; moderate quality evidence), receiving more than one dose of surfactant (typical RR 1.57, 95% CI 1.29 to 1.92; typical RD 0.14, 95% CI 0.08 to 0.20; NNTH 7, 95% CI 5 to 13; 6 studies and 786 infants), and patent ductus arteriosus (PDA) requiring treatment (typical RR 1.86, 95% CI 1.28 to 2.70; typical RD 0.28, 95% CI 0.13 to 0.43; NNTH 4, 95% CI 2 to 8; 3 studies and 137 infants) in infants treated with modified bovine minced lung surfactant extract compared with porcine minced lung surfactant extract. In the subgroup analysis based on initial dose of surfactant, improvement in mortality prior to discharge (typical RR 1.62, 95% CI 1.11 to 2.38; typical RD 0.06, 95% CI 0.01 to 0.11; NNTH 16, 95% CI 9 to 100) and risk of death or oxygen requirement at 36 weeks' postmenstrual age (typical RR 1.39, 95% CI 1.08 to 1.79; typical RD 0.13, 95% 0.03 to 0.23; NNTH 7, 95% CI 4 to 33) was limited to higher initial dose of porcine minced lung surfactant (> 100 mg/kg). Other comparisons: No difference in outcome was noted between bovine lung lavage surfactant extract versus porcine minced lung surfactant extract. There were no studies comparing bovine lung lavage surfactant extract versus porcine lung lavage surfactant; or porcine minced lung surfactant extract versus porcine lung lavage surfactant. AUTHORS' CONCLUSIONS: Significant differences in clinical outcome were noted in the comparison trials of modified minced lung surfactant extract (beractant) compared with porcine minced lung surfactant extract (poractant alfa) including a significant increase in the risk of mortality prior to discharge, death or oxygen requirement at 36 weeks' postmenstrual age, PDA requiring treatment and "receiving > 1 dose of surfactant" in infants treated with modified bovine minced lung surfactant extract compared with porcine minced lung surfactant extract. The difference in these outcomes was limited to studies using a higher initial dose of porcine minced lung surfactant extract. It is uncertain whether the observed differences are from differences in dose or from source of extraction (porcine vs. bovine) because of the lack of dose-equivalent comparison groups with appropriate sample size. No differences in clinical outcomes were observed in comparative trials between bovine lung lavage surfactant and modified bovine minced lung surfactants.

Secondhand Smoke Exposure Reduction After NICU Discharge: Results of a Randomized Trial.

OBJECTIVE: Premature infants are at high risk for respiratory disease, and secondhand smoke (SHS) exposure further increases their risk for developing respiratory illness and asthma. Yet, SHS exposure remains problematic in this vulnerable population. Our objective was to evaluate the effects of brief asthma education plus motivational interviewing counseling on reducing SHS exposure and improving respiratory outcomes in premature infants compared to asthma education alone. METHODS: Caregivers and their infants ≤32 weeks' gestational age were enrolled after discharge from a neonatal intensive care unit in Rochester, New York, from 2007 to 2011. Participants (N = 165, 61% Medicaid insurance, 35% Black, 19% Hispanic, 59% male) were stratified by infant SHS exposure and randomly assigned to treatment or comparison groups. RESULTS: Caregivers in the treatment group reported significantly more home smoking bans (96% vs 84%, P = .03) and reduced infant contact with smokers after the intervention (40% vs 58%, P = .03), but these differences did not persist long term. At study end (8 months after neonatal intensive care unit discharge), treatment group infants showed significantly greater reduction in salivary cotinine versus comparison (-1.32 ng/mL vs -1.08 ng/mL, P = .04), but no significant differences in other clinical outcomes. CONCLUSIONS: A community-based intervention incorporating motivational interviewing and asthma education may be helpful in reducing SHS exposure of premature infants in the short term. Further efforts are needed to support sustained protections for this high-risk group and ultimately, prevent acute and chronic respiratory morbidity. Strategies for successfully engaging families during this stressful period warrant attention.

Differences in Birth Weight Associated with the 2008 Beijing Olympics Air Pollution Reduction: Results from a Natural Experiment.

BACKGROUND: Previous studies have reported decreased birth weight associated with increased air pollutant concentrations during pregnancy. However, it is not clear when during pregnancy increases in air pollution are associated with the largest differences in birth weight. OBJECTIVES: Using the natural experiment of air pollution declines during the 2008 Beijing Olympics, we evaluated whether having specific months of pregnancy (i.e., 1st…8th) during the 2008 Olympics period was associated with larger birth weights, compared with pregnancies during the same dates in 2007 or 2009. METHODS: Using n = 83,672 term births to mothers residing in four urban districts of Beijing, we estimated the difference in birth weight associated with having individual months of pregnancy during the 2008 Olympics (8 August-24 September 2008) compared with the same dates in 2007 and 2009. We also estimated the difference in birth weight associated with interquartile range (IQR) increases in mean ambient particulate matter ≤ 2.5 µm in aerodynamic diameter (PM2.5), sulfur dioxide (SO2), nitrogen dioxide (NO2), and carbon monoxide (CO) concentrations during each pregnancy month. RESULTS: Babies whose 8th month of gestation occurred during the 2008 Olympics were, on average, 23 g larger (95% CI: 5 g, 40 g) than babies whose 8th month occurred during the same calendar dates in 2007 or 2009. IQR increases in PM2.5 (19.8 µg/m3), CO (0.3 ppm), SO2 (1.8 ppb), and NO2 (13.6 ppb) concentrations during the 8th month of pregnancy were associated with 18 g (95% CI: -32 g, -3 g), 17 g (95% CI: -28 g, -6 g), 23 g (95% CI: -36 g, -10 g), and 34 g (95% CI: -70 g, 3 g) decreases in birth weight, respectively. We did not see significant associations for months 1-7. CONCLUSIONS: Short-term decreases in air pollution late in pregnancy in Beijing during the 2008 Summer Olympics, a normally heavily polluted city, were associated with higher birth weight.

Cumulative neonatal oxygen exposure predicts response of adult mice infected with influenza A virus.

An acceptable level of oxygen exposure in preterm infants that maximizes efficacy and minimizes harm has yet to be determined. Quantifying oxygen exposure as an area-under-the curve (OAUC ) has been predictive of later respiratory symptoms among former low birth weight infants. Here, we test the hypothesis that quantifying OAUC in newborn mice can predict their risk for altered lung development and respiratory viral infections as adults. Newborn mice were exposed to room air or a FiO2 of 100% oxygen for 4 days, 60% oxygen for 8 days, or 40% oxygen for 16 days (same cumulative dose of excess oxygen). At 8 weeks of age, mice were infected intranasally with a non-lethal dose of influenza A virus. Adult mice exposed to 100% oxygen for 4 days or 60% oxygen for 8 days exhibited alveolar simplification and altered elastin deposition compared to siblings birthed into room air, as well as increased inflammation and fibrotic lung disease following viral infection. These changes were not observed in mice exposed to 40% oxygen for 16 days. Our findings in mice support the concept that quantifying OAUC over a currently unspecified threshold can predict human risk for respiratory morbidity later in life.

Respiratory outcomes of the surfactant positive pressure and oximetry randomized trial (SUPPORT).

OBJECTIVE: To explore the early childhood pulmonary outcomes of infants who participated in the National Institute of Child Health and Human Development's Surfactant Positive Airway Pressure and Pulse Oximetry Randomized Trial (SUPPORT), using a factorial design that randomized extremely preterm infants to lower vs higher oxygen saturation targets and delivery room continuous positive airway pressure (CPAP) vs intubation/surfactant. STUDY DESIGN: The Breathing Outcomes Study, a prospective secondary study to the Surfactant Positive Airway Pressure and Pulse Oximetry Randomized Trial, assessed respiratory morbidity at 6-month intervals from hospital discharge to 18-22 months corrected age (CA). Two prespecified primary outcomes-wheezing more than twice per week during the worst 2-week period and cough longer than 3 days without a cold-were compared for each randomized intervention. RESULTS: One or more interviews were completed for 918 of the 922 eligible infants. The incidences of wheezing and cough were 47.9% and 31.0%, respectively, and did not differ between the study arms of either randomized intervention. Infants randomized to lower vs higher oxygen saturation targets had a similar risk of death or respiratory morbidity (except for croup and treatment with oxygen or diuretics at home). Infants randomized to CPAP vs intubation/surfactant had fewer episodes of wheezing without a cold (28.9% vs 36.5%; P<.05), respiratory illnesses diagnosed by a doctor (47.7% vs 55.2%; P<.05), and physician or emergency room visits for breathing problems (68.0% vs 72.9%; P<.05) by 18-22 months CA. CONCLUSION: Treatment with early CPAP rather than intubation/surfactant is associated with less respiratory morbidity by 18-22 months CA. Longitudinal assessment of pulmonary morbidity is necessary to fully evaluate the potential benefits of respiratory interventions for neonates.

Adherence to guidelines for respiratory syncytial virus immunoprophylaxis among infants with prematurity or chronic lung disease in three United States counties.

Among infants with prematurity and/or chronic lung disease for whom respiratory syncytial virus immunoprophylaxis is recommended, we examined adherence in infants enrolled during healthcare visits for acute respiratory illness in 3 U.S. counties from 2001 to 2007. Immunoprophylaxis among infants who met national criteria for prophylaxis increased from 33% to 83% over the 6-year period; 17% (11/65) of infants who received immunoprophylaxis did not meet eligibility criteria.

Evidence-based approach to preventing central line-associated bloodstream infection in the NICU.

AIM: To review care practices and methods of implementation that reduce the risk of central line-associated bloodstream infection (CLABSI). METHODS: Medical and quality improvement-oriented literature was reviewed. RESULTS: Although effective catheter practices, equipment and staff training methods are available to reduce CLABSI, their implementation is often difficult. CONCLUSION: A successful CLABSI reduction programme requires not only identification of best practices but also understanding of the specific context or unit culture into which they will be introduced.

An evidence-based catheter bundle alters central venous catheter strategy in newborn infants.

OBJECTIVE: To assess whether introduction of an evidence-based percutaneously inserted central catheter (PICC) care bundle reduced the risk of central line-associated bloodstream infection (CLABSI), thus altering the comparative risk of CLABSI in infants. STUDY DESIGN: This retrospective cohort study included all infants for whom an umbilical venous catheter (UVC) was placed as part of routine care between Jan 1, 2006, and Dec 31, 2009, a period during which standardized PICC insertion and care bundles were introduced. Duration of UVC use was divided in ≤ 7 days and >7 days. RESULTS: Infants in the ≤ 7 days UVC group had 1.0 CLABSI/1000 catheter days, and infants in the >7 days UVC group had 4.0 CLABSI/1000 catheter days (P < .001). Controlling for birth weight, gestational age, and antibiotic use, the >7 days UVC group had a greater risk of CLABSI (OR, 5.48) than the ≤ 7 days UVC group. CLABSI rate increased more rapidly in UVC than PICC with increasing duration of catheter rose. CONCLUSIONS: Replacement of a UVC with a PICC when central venous access is needed after 7 days of age may reduce CLABSI.

Statewide NICU central-line-associated bloodstream infection rates decline after bundles and checklists.

OBJECTIVE: In 2008, all 18 regional referral NICUs in New York state adopted central-line insertion and maintenance bundles and agreed to use checklists to monitor maintenance-bundle adherence and report checklist use. We sought to confirm whether adopting standardized bundles and using central-line maintenance checklists reduced central-line-associated bloodstream infections (CLABSI). METHODS: This was a prospective cohort study that enrolled all neonates with a central line who were hospitalized in any of 18 NICUs. Each NICU reported CLABSI and central-line utilization data and checklist use. We used χ(2) to compare CLABSI rates in the preintervention (January to December 2007) versus the postintervention (March to December 2009) periods and Poisson regression to model adjusted CLABSI rates. RESULTS: Each study period included more than 55 000 central-line days and more than 200 000 patient-days. CLABSI rates decreased 67% statewide (risk ratio: 0.33 [95% confidence interval: 0.27-0.41]; P < .0005); after adjusting for the altered central-line-associated bloodstream infection definition in 2008, by 40% (risk ratio: 0.60 [95% confidence interval: 0.48-0.75]; P < .0005). A total of 13 of 18 NICUs reported using maintenance checklists for 10% to 100% of central-line days. The checklist-use rate was associated with the CLABSI rate (coefficient: -0.57, P = .04). A total of 10 of 18 NICUs were independent CLABSI rate predictors, ranging from 1 site with greatly reduced risk (incidence rate ratio: 0.04, P < .0005) to 1 site with greatly increased risk (incidence rate ratio: 2.87, P < .0005). CONCLUSIONS: Although standardizing central-line care elements led to a significant statewide decline in NICU CLABSIs, site of care remains an independent risk factor. Using maintenance checklists reduced CLABSIs.

Infant race affects application of clinical guidelines when screening for drugs of abuse in newborns.

BACKGROUND: Screening for illicit drugs in newborns has privacy, social, and legal risks for families of the infants. Established drug-screening criteria may be applied in a manner that considers nonproven risk factors such as race in addition to evidence-based factors. OBJECTIVE: The goal of this study was to determine if race was used as a criterion for screening infants for intrauterine cocaine exposure. We hypothesized that infants of black mothers would be more likely to be screened regardless of whether they met the standard criteria for screening of our institution's NICU. METHODS: We used the electronic medical records of newborn infants and their mothers to determine which mother-infant pairs had documented evidence of meeting the criteria for screening infants for prenatal exposure to illicit drugs set forth in the guidelines of our NICU. We then assessed the rates of drug screening to determine the strongest predictors of whether an infant would be screened. RESULTS: We assessed 2121 mother-infant pairs. Infants born to black mothers were more likely than those born to white mothers to have screening performed whether they met screening criteria (35.1% vs 12.9%; P < .001) or did not (5.3% vs 1.2%; P < .001). In a logistic regression analysis, black race remained independently associated (odds ratio: 2.17 [95% confidence interval: 1.25-3.79]) with drug screening even when we controlled for our standard screening criteria and income, insurance status, and maternal education. CONCLUSION: Providers seemed to have used race, in addition to recognized risk criteria, as a factor in deciding whether to screen an infant for maternal illicit drug use.

Effect of cumulative oxygen exposure on respiratory symptoms during infancy among VLBW infants without bronchopulmonary dysplasia.

UNLABELLED: Very low birth weight (VLBW) infants, even those without bronchopulmonary dysplasia (BPD) are at risk for pulmonary morbidity during infancy. Although some studies have found an association between the level of neonatal oxygen exposure and later morbidity, others have not. A possible explanation for these inconsistent findings is that the cumulative dosage of neonatal supplemental oxygen to which infants are exposure is difficult to accurately quantify. METHODS: A prospective cohort study of VLBW infants without BPD was performed to test the hypothesis that cumulative oxygen exposure in the neonatal period summarized using an area under the curve analysis (Oxygen(AUC)) is predictive of later pulmonary symptoms. Risk factors tested in the analysis included both neonatal and outpatient respiratory exposures. Outcome measures included respiratory symptoms and use of medications and health services to treat those symptoms. RESULTS: The prevalence of pulmonary symptoms after NICU discharge was 48% (36 of 75 patients). Oxygen(AUC) as early as 72 hr of age predicts respiratory symptoms and respiratory-related health service and medication use during infancy in a dose dependent manner. Oxygen(AUC) is a stronger predictor of later respiratory symptoms than is the number of days of supplemental oxygen or positive pressure respiratory therapy or integrated mean airway pressure (MAP(AUC)). CONCLUSIONS: Oxygen(AUC) as early as 72 hr of age is predictive of later respiratory symptoms and use of health services and medications to treat those symptoms. Supplemental oxygen therapy should be monitored carefully to minimize oxygen exposure and risk of later respiratory symptoms in VLBW infants.
