Regional Variation in Neonatal Intensive Care Admissions and the Relationship to Bed Supply

To characterize geographic variation in neonatal intensive care unit (NICU) admission rates across the entire birth cohort and evaluate the relationship between regional bed supply and NICU admission rates. This was a population-based, cross-sectional study. 2013 US birth certificate and 2012 American Hospital Association data were used to assign newborns and NICU beds to neonatal intensive care regions. Descriptive statistics of admission rates were calculated across neonatal intensive care regions. Multilevel logistic regression was used to examine the relationship between bed supply and individual odds of admission, with adjustment for maternal and newborn characteristics. Among 3 304 364 study newborns, the NICU admission rate was 7.2 per 100 births and varied across regions for all birth weight categories. IQRs in admission rates were 84.5-93.2 per 100 births for 500-1499 g, 35.3-46.1 for 1500-2499 g, and 3.5-5.5 for ≥2500 g. Adjusted odds of admission for newborns of very low birth weight were unrelated to regional bed supply; however, newborns ≥2500 g in regions with the highest NICU bed supply were significantly more likely to be admitted to a NICU than those in regions with the lowest (aOR 1.20 [1.03-1.40]). There is persistent underuse of NICU care for newborns of very low birth weight that is not associated with regional bed supply. Among larger newborns, we find evidence of supply-sensitive care, raising concerns about the potential overuse of expensive and unnecessary care. Rather than improving access to needed care, NICU expansion may instead further deregionalize neonatal care, exacerbating underuse.

Nutritional Practices and Growth in Premature Infants After Surgical Necrotizing Enterocolitis.

The aim of the study was to describe the nutritional provisions received by infants with surgical necrotizing enterocolitis (NEC) and the associated effects on short-term growth. Through the Children's Hospitals Neonatal Database, we identified infants born ≤32 weeks' gestation with surgical NEC from 5 regional neonatal intensive care units for 4 years. Excluded infants had isolated intestinal perforation and died <14 days postoperatively. Infants were stratified by their median parenteral protein dose (low [LP] or high [HP] protein) for the first postoperative week. The primary outcome was postoperative weight growth velocity. Growth (weight, length, and head circumference [HC]) was measured and the effects related to protein dose were estimated using multivariable analyses. There were 103 infants included; the median parenteral protein dose received was 3.27 g · kg · day (LP: 2.80 g · kg · day; HP: 3.87 g · kg · day). Postoperative weight (11.5 ± 6.5 g · kg · day) and linear growth (0.9 ± 0.2 cm/wk) were similar regardless of dose (P > 0.3 between groups for weight and length). Unadjusted and independent associations were identified with HC changes and HP dose (β = 0.1 cm/wk, P = 0.03) after adjusting for gestational age, the presence of severe bronchopulmonary dysplasia, short bowel syndrome, blood stream infection, severe intraventricular hemorrhage, small for gestational age, and calorie intake. Eventual nonsurvivors received 18% less protein and 14% fewer calories over the first postoperative month. Postoperative protein doses in infants with surgical NEC appear related to increases in HC. The influence of postoperative nutritional support on risk of adverse outcomes deserves further attention.

BackgroundIntravitreal bevacizumab (IVB) has emerged as an effective treatment modality for the management of retinopathy of prematurity (ROP) where the disease is severe and posterior. Despite evidence of systemic vascular...

Dwell time and risk of central-line-associated bloodstream infection in neonates

Umbilical venous catheters (UVCs) or peripherally inserted central catheters (PICCs), widely used in high-risk neonates, may have a threshold dwell time for subsequent increased risk of central-line-associated bloodstream infection (CLABSI). To evaluate the CLABSI risks in neonates having either UVC, PICC, or those having both sequentially. The study included 3985 infants who had UVC or PICC inserted between 2007 and 2009 cared for in 10 regional neonatal intensive care units: 1392 having UVC only (group 1), 1317 PICC only (group 2), and 1276 both UVC and PICC (group 3). There were 403 CLABSIs among 6000 venous catheters inserted, totalling 43,302 catheter-days. CLABSI rates were higher in group 3 infants who were of lowest gestation (16.9 per 1000 UVC-days and 12.5 per 1000 PICC-days; median: 28 weeks) when compared with group 1 (3.3 per 1000 UVC-days; 37 weeks) and group 2 (4.8 per 1000 PICC-days; 30 weeks). Life table and Kaplan-Meier hazard analysis showed that UVC CLABSI rate increased stepwise to 42 per 1000 UVC-days by day 10, with the highest rate in group 3 (85 per 1000 UVC-days). PICC CLABSI rates remained relatively stable at 12-20 per 1000 PICC-days. Compared to PICC, UVC had a higher adjusted CLABSI risk controlled for dwell time. Among group 3, replacing UVC electively before day 4 may have a trend of lower CLABSI risk than late replacement. There was no cut-off duration beyond which PICC should be removed electively. Early UVC removal and replacement by PICC before day 4 might be considered.

Transition from an open-plan to a two-cot neonatal intensive care unit: a participatory action research approach.

To facilitate staff transition from an open-plan to a two-cot neonatal intensive care unit design. In 2012, an Australian regional neonatal intensive care unit transitioned from an open-plan to a two-cot neonatal intensive care unit design. Research has reported single- and small-room neonatal intensive care unit design may negatively impact on the distances nurses walk, reducing the time they spend providing direct neonatal care. Studies have also reported nurses feel isolated and need additional support and education in such neonatal intensive care units. Staff highlighted their concerns regarding the impact of the new design on workflow and clinical practice. A participatory action research approach. A participatory action group titled the Change and Networking Group collaborated with staff over a four-year period (2009-2013) to facilitate the transition. The Change and Networking Group used a collaborative, cyclical process of planning, gathering data, taking action and reviewing the results to plan the next action. Data sources included meeting and workshop minutes, newsletters, feedback boards, subgroup reports and a staff satisfaction survey. The study findings include a description of (1) how the participatory action research cycles were used by the Change and Networking Group: providing examples of projects and strategies undertaken; and (2) evaluations of participatory action research methodology and Group by neonatal intensive care unit staff and Change and Networking members. This study has described the benefits of using participatory action research to facilitate staff transition from an open-plan to a two-cot neonatal intensive care unit design. Participatory action research methodology enabled the inclusion of staff to find solutions to design and clinical practice questions. Future research is required to assess the long-term effect of neonatal intensive care unit design on staff workload, maintaining and supporting a skilled workforce as well as the impact of a new neonatal intensive care unit design on the neonatal intensive care unit culture. A supportive work environment for staff is critical in providing high-quality health care.

Homecare and Healthcare Utilization Errors Post-Neonatal Intensive Care Unit Discharge.

Background:High-risk infants transitioning from the neonatal intensive care unit (NICU) to home represent a vulnerable population, given their complex care requirements. Little is known about errors during this period.Purpose:Identify and describe homecare and healthcare utilization errors in high-risk infants following NICU discharge.Methods:This was a prospective observational cohort study of homecare (feeding, medication, and equipment) and healthcare utilization (appointment) errors in infants discharged from a regional NICU between 2011 and 2015. Chi-square test and Wilcoxon rank-sum test were used to compare infant and maternal demographics between infants with and without errors.Results:A total of 363 errors were identified in 241 infants during 635 home visits. The median number of visits was 2. No significance was found between infant and maternal demographics in those with or without errors.Implications of Practice:High-risk infants have complex care needs and can benefit from regular follow-up services. Home visits provide an opportunity to identify, intervene, and resolve homecare and healthcare utilization errors.Implications of Research:Further research is needed to evaluate the prevalence and cause of homecare errors in high-risk infants and how healthcare resources and infant health outcomes are affected by those errors. Preventive measures and mitigating interventions that best address homecare errors require further development and subsequent description.

Estimating the requirement for manipulation of medicines to provide accurate doses for children

Objective To determine the type and frequency of manipulations of drug dosage forms required to administer smaller doses for children and the drugs involved. Methods An experienced paediatric clinical pharmacist estimated the requirement to manipulate a medicine to achieve accurate dose administration from prescription data in all neonatal and paediatric inpatients collected over 5-day periods and information on drug dosage form availability in a regional children's hospital (RCH) and regional paediatric intensive care unit (RPICU), a regional neonatal intensive care unit (RNICU) and paediatric and neonatal wards of a district general hospital (DGH) using paper-based prescribing systems. Doses were expressed by weight. Ward stock supply with some intravenous drugs ready-to-administer was provided. The main outcome measures were the estimated requirement for dosage form manipulation, nature of the manipulation and drug name. Results Of 5375 evaluated drug administrations, 542 (10.1%) were judged to require manipulation or measurement of a small volume (<0.2 ml). The most frequent manipulation was measurement of oral dose in volumes of 0.1 to <0.2 ml in the DGH. Requirement to measure doses of <0.1 ml (oral and intravenous) accounted for 25.2% of all manipulations, with the need to measure intravenous doses of <0.1 ml being most frequent in the RNICU and RPICU (60.4% and 31.9% of manipulations, respectively). Hydrocortisone was the drug most frequently judged to require manipulation with both measurement of small volumes for intravenous injection (RPICU and RNICU) and segmentation of tablets (RCH). Conclusions Manipulation of medicines (including measurement of very small volumes) to provide accurate smaller doses for children is common in the hospital setting.

Neonatal outcomes in a level II regional neonatal intensive care unit.

Improvement of neonatal mortality is a challenge in developing countries such as Iraq due to increased demand and overload of maternity services. The aim of this study was to document the number, disease patterns and outcome of admitted newborns and the improvement after implementation of clinical protocols, and to identify possible future target measures. A descriptive study was conducted at the neonatal intensive care unit (NICU) of a regional hospital from 2011 to 2013. Of 72 320 deliveries, 4694 newborns were admitted and met selection criteria. Clinical guidelines, clinical skills training of nurses and resident doctors, and improvement of medical records were implemented during the study period. All patient demographics, causes of admission/death and mortality were analyzed. From a total of 4694 admitted newborns; 42% were delivered vaginally, 60% were male, 43% were <2500 g, and 31% were premature. The neonatal deaths consisted of 1076 newborns, 84% of whom died before 7 days of age, and 39% of whom weighed ≤1500 g. Respiratory distress syndrome was the main cause of death (62.2%). Due to the increased total number of deliveries, and hence the corresponding increased number of vaginal deliveries (R = 0.97), the number of NICU admissions was significantly increased (R = 0.569, P = 0.009). Notably, the mortality rate was significantly decreased (R = -0.487, P = 0.004). Maternity overload contributed to the high neonatal mortality, whereas implementation of clinical guidelines and of medical staff training improved neonatal outcomes. Future target interventions include optimized timing of cesarean section and the detection of potentially complicated deliveries.

Viral Respiratory Infections in Preterm Infants during and after Hospitalization

ObjectiveTo determine the burden of viral respiratory infections in preterm infants both during and subsequent to neonatal intensive care unit (NICU) hospitalization and to compare this with term infants living in the community.Study designFrom March 2013 through March 2015, we enrolled 189 newborns (96 term and 93 preterm) into a prospective, longitudinal study obtaining nose/throat swabs within 7 days of birth, weekly while hospitalized and then monthly to 4 months after hospital discharge. Taqman array cards were used to identify 16 viral respiratory pathogens by real-time polymerase chain reaction. Demographic, clinical, and laboratory data were gathered from electronic medical records, and parent interview while hospitalized with interval histories collected at monthly visits. The hospital course of all preterm infants who underwent late-onset sepsis evaluations was reviewed.ResultsOver 119 weeks, we collected 618 nose/throat swabs from at risk preterm infants in our level IV regional NICU. Only 4 infants had viral respiratory infections, all less than 28 weeks gestation at birth. Two infants were symptomatic with the infections recognized by the clinical team. The daily risk of acquiring a respiratory viral infection in preterm infants in the NICU was significantly lower than in the full term cohort living in the community. Once discharged from the hospital, viral respiratory infections were common in all infants.ConclusionsViral respiratory infections are infrequent in a NICU with strict infection prevention strategies and do not appear to cause unrecognized illness. Both preterm and term infants living in the community quickly acquire respiratory viral infections.

Therapeutic Hypothermia During Neonatal Transport: Active Cooling Helps Reach the Target.

Perinatal hypoxic ischemic encephalopathy (HIE) can lead to severe neurodevelopmental outcome and death. Therapeutic hypothermia is neuroprotective for infants with moderate-to-severe HIE. However, therapeutic hypothermia is only offered at high-level regional neonatal intensive care units (NICUs), necessitating the need to transport sick infants to referral centers. The goal of this study was to evaluate whether active cooling on transport is more effective than passive cooling in achieving temperatures in the treatment target range (33°C-34°C) on arrival to the Texas Children's Hospital (TCH) NICU. This was a retrospective quasi-experimental study of 42 infants who were transported to TCH for treatment of perinatal HIE between August 2012 and April 2016. Active cooling using a continuous core temperature servo-controlled cooling device (CritiCool) began in January 2014; before that, passive cooling on transport was used. Passive cooling was initiated by turning off external heating devices. Fourteen infants received active cooling, and 28 were passively cooled. Demographic data, gestational age at birth, birth weight, and Sarnat stage were not different between groups. Although TCH arrival temperatures were not different between the groups (p = 0.841), there was greater variability of temperatures in the passively cooled group (p = 0.001). More actively versus passively cooled patients arrived at the cooling center within the goal temperature range (79% vs. 25%, p = 0.003). After controlling for multiple variables, active cooling was a significant independent predictor for arriving at the cooling center within the goal temperature range. Active cooling during transport of infants with moderate-to-severe HIE was more effective than passive cooling in achieving the target goal temperature range on arrival at the cooling center. If cooling is being considered during transport, we suggest that active servo-controlled therapeutic hypothermia be used.

The impact of a sepsis quality improvement project on neurodisability rates in very low birthweight infants

ObjectiveVery low birthweight (VLBW; <1500 g) infants with late-onset sepsis (LOS) have an increased risk of neurodisability. Care bundles to reduce bloodstream infections in neonatal intensive care unit (NICU) are...

Clinical impact of term-equivalent magnetic resonance imaging in extremely low-birth-weight infants at a regional NICU.

To evaluate the clinical impact of routine term-equivalent magnetic resonance imaging (TE-MRI) for extremely low-birth-weight infants at a regional neonatal intensive care unit. This is a single-center retrospective study evaluating preterm survivors who underwent TE-MRI. MRI abnormalities were compared between infants with and without cranial ultrasonography (CUS) abnormalities. Cost analysis comparing imaging modalities was also performed. TE-MRI use increased from 17% in 2006 to 76% in 2010. MRI detected new findings in nearly half of infants, whether or not they had known ultrasound abnormalities. MRI detected more cerebellar (18% vs 6%, P=0.04) and moderate white matter injury (12% vs 7%, P<0.001), and altered simulated neurological prognosis across developmental domains. The cost of TE-MRI was $1600, which was comparable to serial CUSs. TE-MRI detects new abnormalities and impacts developmental prognosis in the extremely low birth weight, which supports its use despite the added financial cost.

Acute Kidney Injury Urine Biomarkers in Very Low-Birth-Weight Infants.

Serum creatinine (SCr)-based AKI definitions have important limitations, particularly in very low-birth-weight (VLBW) neonates. Urine biomarkers may improve our ability to detect kidney damage. We assessed the association between 14 different urine biomarkers and AKI in VLBW infants. We performed a prospective cohort study on 113 VLBW infants (weight ≤1200 g or <31 weeks' gestation) admitted to a regional neonatal intensive care unit at the University of Alabama at Birmingham between February 2012 and June 2013. SCr was measured on postnatal days 1, 2, 3, and 4 and was combined with clinically measured SCr to determine AKI according to Kidney Disease Improving Global Outcomes AKI definition (increase in SCr ≥0.3 mg/dl or ≥50% increase from previous lowest value). Urine was collected on the first 4 days (average number of urine collections, 3; range, 1-4). The maximum urine biomarkers and urine biomarker/creatinine levels were calculated for 12 urine biomarkers, and the minimum urine biomarker and biomarker/creatinine levels were assessed for two urine biomarkers. We compared these values between infants with and those without AKI. Ideal cutoffs, area under the receiver-operating characteristic curve , and area under the curve adjusted for gestational age were calculated. Cumulative incidence of AKI during the first 2 postnatal weeks was 28 of 113 (25%). Infants with AKI had higher maximum levels of urine cystatin C, neutrophil gelatinase-associated lipocalin, osteopontin, clusterin, and α glutathione S-transferase (2.0, 1.8, 1.7, 1.7, and 3.7 times higher, respectively) than infants without AKI. In addition, infants with AKI had lower minimum levels of epithelial growth factor and uromodulin than those without AKI (1.4 and 1.6 times lower, respectively). Most but not all participants had their maximum (or minimum) biomarker values preceding AKI. These associations remained after adjustment for gestational age. Urine biomarkers measured in the first 4 days of life are associated with AKI during the first postnatal weeks. Further evaluations are necessary to determine whether these biomarkers can predict important clinical outcomes. In addition, intervention studies that use biomarkers to stratify enrollment groups are needed before bedside evaluations can be incorporated into care.

Inhaled nitric oxide use in preterm infants in California neonatal intensive care units.

ObjectiveTo describe inhaled nitric oxide (iNO) exposure in preterm infants and variation in Neonatal Intensive Care Unit (NICU) use.Study DesignThis was a retrospective cohort study of infants, 22–33+6/7 weeks gestational age (GA), during 2005–2013. Analyses were stratified by GA and included population characteristics, iNO use over time and hospital variation.ResultOf 65 824 infants, 1 718 (2.61%) received iNO. Infants, 22–24+6/7 weeks GA, had the highest incidence of iNO exposure (6.54%). Community NICUs (n = 77, median hospital use rate 0.7%) used less iNO than regional NICUs (n = 23, median hospital use rate 5.8%). In 22–24+6/7 week GA infants the median rate in regional centers was 10.6% (hospital IQR 3.8%–22.6%).ConclusioniNO exposure varied with GA and hospital level, with the most use in extremely premature infants and regional centers. Variation reflects a lack of consensus regarding the appropriate use of iNO for preterm infants.

Intercenter Cost Variation for Perinatal Hypoxic-Ischemic Encephalopathy in the Era of Therapeutic Hypothermia

To quantify intercenter cost variation for perinatal hypoxic ischemic encephalopathy (HIE) treated with therapeutic hypothermia across children's hospitals. Prospectively collected data from the Children's Hospitals Neonatal Database and Pediatric Health Information Systems were linked to evaluate intercenter cost variation in total hospitalization costs after adjusting for HIE severity, mortality, length of stay, use of extracorporeal support or nitric oxide, and ventilator days. Secondarily, costs for intensive care unit bed, electroencephalography (EEG), and laboratory and neuroimaging testing were also evaluated. Costs were contextualized by frequency of favorable (survival with normal magnetic resonance imaging) and adverse (death or need for gastric tube feedings at discharge) outcomes to identify centers with relative low costs and favorable outcomes. Of the 822 infants with HIE treated with therapeutic hypothermia at 19 regional neonatal intensive care units, 704 (86%) survived to discharge. The median cost/case for survivors was $58 552 (IQR $32 476-$130 203) and nonsurvivors $29 760 (IQR $16 897-$61 399). Adjusting for illness severity and select interventions, intercenter differences explained 29% of the variation in total hospitalization costs. The widest cost variability across centers was EEG use, although low cost and favorable outcome centers ranked higher with regards to EEG costs. There is marked intercenter cost variation associated with treating HIE across regional children's hospitals. Our investigation may help establish references for cost and enhance quality improvement and resource utilization projects related to HIE.

Predicting death or extended length of stay in infants with congenital diaphragmatic hernia.

To predict mortality or length of stay (LOS) >109 days (90th percentile) among infants with congenital diaphragmatic hernia (CDH). We conducted a retrospective analysis using the Children's Hospital Neonatal Database during 2010 to 2014. Infants born >34 weeks gestation with CDH admitted at 22 participating regional neonatal intensive care units were included; patients who were repaired or were at home before admission were excluded. The primary outcome was death before discharge or LOS >109 days. Factors associated with this outcome were used to develop a multivariable equation using 80% of the cohort. Validation was performed in the remaining 20% of infants. The median gestation and age at referral in this cohort (n=677) were 38 weeks and 6 h, respectively. The primary outcome occurred in 242 (35.7%) infants, and was distributed between mortality (n=180, 27%) and LOS >109 days (n=66, 10%). Regression analyses showed that small for gestational age (odds ratio (OR) 2.5, P=0.008), presence of major birth anomalies (OR 5.9, P<0.0001), 5- min Apgar score ⩽3 (OR 7.0, P=0.0002), gradient of acidosis at the time of referral (P<0.001), the receipt of extracorporeal support (OR 8.4, P<0.0001) and bloodstream infections (OR 2.2, P=0.004) were independently associated with death or LOS >109 days. This model performed well in the validation cohort (area under curve (AUC)=0.856, goodness-of-fit (GF) χ(2), P=0.16) and acted similarly even after omitting extracorporeal support (AUC=0.82, GF χ(2), P=0.05). Six variables predicted death or LOS ⩾109 days in this large, contemporary cohort with CDH. These results can assist in risk adjustment for comparative benchmarking and for counseling affected families.

Utility of Targeted Neonatal Echocardiography in the Management of Neonatal Illness.

To describe the impact of targeted neonatal echocardiography on management of neonatal illness in a tertiary perinatal center neonatal intensive care unit (NICU). We conducted a retrospective analysis of consecutive targeted neonatal echocardiographic studies that were performed over an 18-month period in a regional perinatal center NICU in Canada. All studies were performed with a cardiovascular ultrasound machine and transducer and read on a workstation with storage and analysis software. Reporting was done on a standardized document, and any management change resulting from targeted neonatal echocardiography was documented. A total of 303 consecutive targeted neonatal echocardiographic studies were performed on 129 neonates. The mean gestational age ± SD was 27.8 ± 4.3 weeks (range, 23-41 weeks), and the mean birth weight ± SD was 1196 ± 197 g (range, 490- 4500 g). The median number of studies per neonate was 2 (range, 1-8), with most repeated studies for a patent ductus arteriosus (PDA). The most common indication for echocardiography was assessment of a PDA (52.1%), followed by early global hemodynamic assessment of very low birth weight (16.2%) and pulmonary hypertension (12.2%). Of the 303 studies, 126 (41.5%) resulted in management changes. The contribution to management was significantly related to the timing of echocardiography. Around half of the echocardiographic examinations during first the week of life resulted in management changes, compared to 22% of studies after 1 week of age (P = .002). Patent ductus arteriosus management accounted for almost half of the interventions. Targeted neonatal echocardiography is a valuable tool in the NICU and can contribute substantially to hemodynamic management in the first week of life, PDA management in the first 2 weeks of life, and cases of hypotension or shock at any time during the hospital stay.

Short-term outcomes and medical and surgical interventions in infants with congenital diaphragmatic hernia.

The aim of this study is to characterize medical and surgical therapies and short-term outcomes in infants with congenital diaphragmatic hernia (CDH). Retrospective analysis of CDH infants admitted to 27 children's hospitals submitting data to Children's Hospital Neonatal Database (CHND) from 2010 to 2013, stratified by gestational age, birth weight, and survival. A total of 572 infants were identified, 508 (89%) born ≥ 34 weeks' gestation and ≥ 2 kg. More mature infants had higher APGAR scores, shorter duration of mechanical ventilation, and were more likely to receive extracorporeal membrane oxygenation (ECMO). Overall, mortality for the cohort was 29%, with mortality lower in infants born ≥ 34 weeks' gestation and ≥ 2 kg (26 vs. 50%, p < 0.01). Nonsurvivors were more likely to receive treatment with high-frequency oscillatory ventilation (HFOV), vasopressors, pulmonary vasodilators, and ECMO, and to have associated major congenital anomalies than survivors. In hospital morbidity and complications were relatively uncommon among survivors. Infants with CDH have a high risk of morbidity and mortality, and for preterm infants with CDH those risks are amplified. Patterns of respiratory and circulatory support appeared to be different for survivors. In addition to established data registries, this consortium of regional neonatal intensive care units provides a new collaborative effort to describe short-term outcomes for infants referred with CDH.

Does timing of initial surfactant treatment make a difference in rates of chronic lung disease or mortality in premature infants? An observational regional study

Objective: To compare two treatment strategies in preterm infants with or at risk of respiratory distress syndrome: early surfactant administration (within one hour of birth) versus late surfactant administration, in a geographically defined population.Outcome: The primary outcome was chronic lung disease (CLD) and mortality before/at 36 weeks. Secondary outcomes included: duration of mechanical ventilation and continuous positive airway pressure (CPAP), post-natal steroids for CLD and major neonatal morbidities.Subjects: Premature infants born at 22–32 weeks’ gestation between January 2006 and December 2009.Setting: Ten neonatal intensive care units (NICUs) in New South Wales (NSW) and Australian Capital Territory (ACT), Australia.Design: Retrospective analysis of prospectively collected data from the regional NICU database in NSW and ACT.Results: Of the 2170 infants who received surfactant, 1182 (54.5%) and 988 (45.5%) received early and late surfactant, respectively. The early surfactant group was less mature (27.1 ± 2.1 versus 29.4 ± 2.1 weeks) and had more CLD and mortality (40.2% versus 20.0%). The multivariable analysis showed early surfactant to be associated with less duration of ventilation, longer duration of CPAP and longer hospital stay but had little or no impact on CLD/mortality.Conclusion: Early surfactant administration is associated with shorter duration of ventilation but does not appear to be significantly protective against CLD/mortality among premature infants. This may support the growing evidence for consideration of CPAP as an alternative to routine intubation and early surfactant administration. Further investigation from large randomized clinical trials is warranted to confirm these results.

Referral of Very Low Birth Weight Infants to High-Risk Follow-Up at Neonatal Intensive Care Unit Discharge Varies Widely across California

To determine rates and factors associated with referral to the California Children's Services high-risk infant follow-up (HRIF) program among very low birth weight (BW) infants in the California Perinatal Quality of Care Collaborative. Using multivariable logistic regression, we examined independent associations of demographic and clinical variables, neonatal intensive care unit (NICU) volume and level, and California region with HRIF referral. In 2010-2011, 8071 very low BW infants were discharged home; 6424 (80%) were referred to HRIF. Higher odds for HRIF referral were associated with lower BW (OR 1.9, 95% CI 1.5-2.4; ≤ 750 g vs 1251-1499g), higher NICU volume (OR 1.6, 1.2-2.1; highest vs lowest quartile), and California Children's Services Regional level (OR 3.1, 2.3-4.3, vs intermediate); and lower odds with small for gestational age (OR 0.79, 0.68-0.92), and maternal race African American (OR 0.58, 0.47-0.71) and Hispanic (OR 0.65, 0.55-0.76) vs white. There was wide variability in referral among regions (8%-98%) and NICUs (<5%-100%), which remained after risk adjustment. There are considerable disparities in HRIF referral, some of which may indicate regional and individual NICU resource challenges and barriers. Understanding demographic and clinical factors associated with failure to refer present opportunities for targeted quality improvement initiatives.
