RESUMO
Quality improvement collaboratives (QICs) use their collective experiences from participating centers to accelerate the translation of evidence into practice, resulting in reduced variation and improved clinical outcomes. There are several regional, national, and international QICs in neonatology. In this review, we discuss the framework and evaluate national QICs primarily based in US and share the contributions of selected studies. We found that the QICs in neonatology play a significant role in identification of target topics, developing best practices, improving provider knowledge, building QI capacity, and improving outcomes. The key strengths of QICs are that they produce more generalizable learnings, involve a larger patient population which enhances statistical analysis, and offer resources to smaller institutions. Limitations include institutions contributing unequally to the overall results, difficulty in interpreting results when multiple improvement strategies are applied simultaneously, and the possible lack of academic recognition for individual center leadership.
RESUMO
OBJECTIVE: Routine blood gas measurements are common in infants with severe bronchopulmonary dysplasia (sBPD) and are a noxious stimulus. We developed a guideline-driven approach to evaluate the care of infants with sBPD without routine blood gas sampling in the chronic phase of NICU care (after diagnosis at 36 weeks PMA). STUDY DESIGN: We examined blood gas utilization and outcomes in our sBPD inpatient care unit using data collected between 2014 and 2020. RESULTS: 485 sBPD infants met inclusion criteria, and 303 (62%) never had a blood gas obtained after 36 weeks PMA. In infants who had blood gas measurements, the median number of total blood gases per patient was only 4 (IQR 1-10). We did not identify adverse effects on hospital outcomes in patients without routine blood gas measurements. CONCLUSIONS: We found that patients with established BPD could be managed without routine blood gas analyses after 36 weeks PMA.

OBJECTIVES: This quality improvement initiative aimed to decrease unrelieved postoperative pain and improve family satisfaction with pain management. METHODS: NICUs within the Children's Hospitals Neonatal Consortium that care for infants with complex surgical problems participated in this collaborative. Each of these centers formed multidisciplinary teams to develop aims, interventions, and measurement strategies to test in multiple Plan-Do-Study-Act cycles. Centers were encouraged to adopt evidence-based interventions from the Clinical Practice Recommendations, which included pain assessment tools, pain score documentation, nonpharmacologic treatment measures, pain management guidelines, communication of a pain treatment plan, routine discussion of pain scores during team rounds, and parental involvement in pain management. Teams submitted data on a minimum of 10 surgeries per month, spanning from January to July 2019 (baseline), August 2019 to June 2021 (improvement work period), and July 2021 to December 2021 (sustain period). RESULTS: The percentage of patients with unrelieved pain in the 24-hour postoperative period decreased by 35% from 19.5% to 12.6%. Family satisfaction with pain management measured on a 3-point Likert scale with positive responses ≥2 increased from 93% to 96%. Compliance with appropriate pain assessment and numeric documentation of postoperative pain scores according to local NICU policy increased from 53% to 66%. The balancing measure of the percentage of patients with any consecutive sedation scores showed a decrease from 20.8% at baseline to 13.3%. All improvements were maintained during the sustain period. CONCLUSIONS: Standardization of pain management and workflow in the postoperative period across disciplines can improve pain control in infants.

OBJECTIVE: Infants with severe bronchopulmonary dysplasia (sBPD) have complex medical courses. We developed the clinician-rated Optimal State Scoring Tool (OSST) that measures factors relevant to clinical improvement of sBPD and investigated preliminary validity using linear growth outcome and OSST scores in sBPD patients. METHODS: Tool development process and pilot findings are provided for 13 patients evaluated longitudinally. OSST scores, length measurements, and steroid dependency values were obtained. Changes in OSST scores and lengths were examined using linear mixed-effect models. RESULTS: OSST scores were significantly correlated with linear growth (95% CI 0.36, 0.57). The steroid-dependent group showed significantly slower rate of linear growth (95% CI 0.74, 1.05) and slower rate of increase in OSST scores (95% CI 0.99, 2.13) compared to the non-steroid-dependent group, with the OSST showing the largest effect size. CONCLUSION: Pilot data reflect promising evidence for OSST construct validity in monitoring clinical outcomes in sBPD patients.

OBJECTIVE: To implement a quality improvement (QI) scorecard as a tool for enhancing quality and safety efforts in level 1 and 2 community hospital nurseries affiliated with Nationwide Children's Hospital. STUDY DESIGN: A QI scorecard was developed for data collection, analytics, and reporting of neonatal quality metrics and cross-sector collaboration. Newborn characteristics were included for risk stratification, as were clinical and process measures associated with neonatal morbidity and mortality. Quality and safety activities took place in community hospital newborn nurseries in Ohio, and education was provided in both online and in-person collaborations, followed by local team sessions at partner institutions. Baseline (first 12 months) and postbaseline comparisons of clinical and process measures were analyzed by logistic regression, adjusting for potential confounders. RESULTS: In logistic regression models, at least 1 center documented improvements in each of the 4 process measures, and 3 of the 4 centers documented improvements in compliance with glucose checks obtained within 90 minutes of birth among at-risk infants. CONCLUSION: Collaborative QI projects led to improvements in perinatal metrics associated with important outcomes. Formation of a center-driven QI scorecard is feasible and provides community hospitals with a framework for collecting, analyzing, and reporting neonatal QI metrics.

BACKGROUND: Extreme preterm infants face lengthy hospitalizations and are often subjected to painful stimuli. These stimuli may be related to routine caregiving that may negatively impact long-term developmental outcomes. Frequently obtained cuff blood pressure (BP) measurements are an example of a potentially noxious stimulus to preterm infants that may have a cumulating impact on development. PURPOSE: The primary aim was to explore the frequency of cuff BP measurements obtained in hemodynamically stable extreme preterm infants in the neonatal intensive care unit (NICU). Our secondary aim was to reduce the number of cuff BP measurements obtained in hemodynamically stable extreme preterm infants in the NICU. METHODS: Quality improvement methodologies per the Institute for Healthcare Improvement were used combined with a multidisciplinary approach. Participants were infants born less than 27 weeks of gestation and discharged home. The baseline period was 2015 through Q2-2018 and the intervention period was Q3-2018 through Q1-2020. The electronic medical record was used to collect data and Minitab Statistical Software was used for data analysis. FINDINGS/RESULTS: A baseline of 5.0% of eligible patients received the desired number of cuff BP measurements and increased to 63.2% after the intervention period. IMPLICATIONS FOR PRACTICE: Findings demonstrate that using quality improvement methodology can improve clinical care. Findings suggest the feasibility and safety of reducing the number of cuff BP measurements obtained on hemodynamically stable infants in the NICU. IMPLICATIONS FOR RESEARCH: Future endeavors should aim to reduce the quantity of painful stimuli in the NICU. Long-term developmental outcomes should be correlated in these patients.

BACKGROUND: Epidural anesthesia in infants undergoing open abdominal surgery has the potential to reduce opioid consumption, lower pain scores, and expedite tracheal extubation. We evaluated associations between use of continuous epidural chloroprocaine and improved intra- and post-operative outcomes. METHODS: This matched retrospective cohort study first identified 24 patients who between April 2018 through December 2019 were treated with a caudal catheter and epidural chloroprocaine infusion for a laparotomy at postnatal age of 6 months or less. A matched comparator group of 24 patients was derived based on age and type of surgery. Exclusion criteria were the presence of a preoperative opioid infusion, comorbidities that would preclude appropriate pain assessment, or a recent surgical procedure. Primary outcomes included opioid consumption and pain scores; we secondarily analyzed intraoperative anesthetic requirements, other systemic analgesic use, vital signs, tracheal extubation time, and procedural times. RESULTS: Treatment with epidural anesthesia was associated with lower 5-day total postoperative opioid consumption (3.2 mg/kg vs. 19.7 mg/kg in the respective epidural vs. systemic groups, p = 0.001) and time to tracheal extubation (1.3 days vs. 3.2 days, p = 0.005). Any statistically significant differences in pain scores were not clinically meaningful. There were no differences in mean arterial pressure or intraoperative inhaled anesthetic doses. CONCLUSION: Continuous infusion of epidural chloroprocaine in infants following open abdominal surgery may limit exposure to systemic opioid medications while providing adequate postoperative analgesia and shortening time to tracheal extubation.

OBJECTIVES: We pursued the use of regional analgesia (RA) to minimize the use of postoperative opioids. Our aim was to increase the use of postoperative RA for eligible surgical procedures in the NICU from 0% to 80% by June 30, 2019. METHODS: A multidisciplinary team determined the eligibility criteria, developed an extensive process map, implemented comprehensive education, and a structured process for communication of postoperative pain management plans. Daily pain team rounds provided an opportunity for collaborative comanagement. An additional 30 minutes for catheter placement was added in operating room (OR) scheduling so that it would not affect the surgeon OR time. RESULTS: There were 21 eligible surgeries in the baseline period and 34 in the intervention period. In total, 30 of 34 infants in eligible surgeries (88%) received RA. The average total opioid exposure in intravenous morphine milligram equivalents decreased from 5.0 to 1.1 mg/kg in the intervention group. The average time to extubation was 45 hours in the baseline period and 19.9 hours in the intervention group. After interventions, 75% of infants were extubated in the OR, as compared with 10.5% in the baseline period. No difference was seen in postoperative pain scores or postoperative hypothermia between the baseline and intervention groups. CONCLUSIONS: We used quality improvement methodology to develop a structured RA program. We demonstrated a significant reduction in opioid requirements and need for mechanical ventilation postoperatively for those infants who received RA. Our findings support safe and effective use of RA, and provide a framework for implementation of a similar program.

BACKGROUND: Bronchopulmonary Dysplasia (BPD) is the most common prematurity complication. Although several practices have been proposed for BPD prevention, none of these in isolation prevent BPD. METHODS: Our initiative focused on two key drivers: oxygen management and noninvasive ventilation strategies. We created best practice guidelines and followed outcome measures using Shewhart control charts. RESULTS: PDSAs of protocols preceded a large-scale rollout of a "0.21 by 28" campaign in 2014 leading to a special cause reduction in the "any BPD" rate, and a decrease in severe BPD (from 57 to 29%). At the end of 2017, we reinvigorated the project, which led to dramatic decreases in the "any BPD" rate to 41% and the "severe BPD" rate to 21%. CONCLUSIONS: A multidisciplinary QI initiative focused on process improvement geared towards the pathophysiological contributors of BPD has successfully reduced the rate of BPD in an all referral level IV NICU.

BACKGROUND AND OBJECTIVES: Delays with enteral and oral feeding milestones among premature infants with bronchopulmonary dysplasia (BPD) can be due to provider variation or infant-dependent factors. Our objectives with this study were to compare aerodigestive milestones and length of stay in BPD infants after implementing a quality improvement program to improve feeding outcomes. METHODS: Using the Institute for Healthcare Improvement model for quality improvement, we implemented the simplified, individualized, milestone-targeted, pragmatic, longitudinal, and educational (SIMPLE) feeding strategy to enhance feeding and aerodigestive milestones among BPD infants. The key interventions addressed were as follows: (1) enteral feed initiation and advancement protocol; (2) oral feeding progression guidelines, optimization of respiratory support, feeding readiness scores, nonnutritive breastfeeding, and cue-based feeding; (3) active multidisciplinary collaboration; and (4) family-centered care. Comparisons were made between baseline (January 2009 to March 2010) and SIMPLE feeding strategy (May 2010 to December 2013) groups. Both groups included infants between 23 0/7 and 32 6/7 weeks' birth gestation, and ≤34 weeks' postmenstrual age at admission and discharge. RESULTS: The baseline group and SIMPLE feeding group included 92 patients and 187 patients, respectively. Full enteral feeding, first oral feeding, full oral feeding, and length of stay milestones were (all P < .05) achieved sooner in the SIMPLE feeding group. Although the overall prevalence of BPD in the 2 groups is similar, the incidence of moderate BPD has decreased (P < .05) and severe BPD has increased (P < .05) in the SIMPLE feeding group. CONCLUSIONS: SIMPLE feeding strategy advances postnatal maturation and acquisition of feeding milestones irrespective of the severity of BPD and impacts the length of stay, thereby lowering resource use.

BACKGROUND: Skin-to-skin care (SSC) for infants improves physiologic stability, pain perception, brain development, parental bonding, and overall survival. Using quality improvement (QI) methodology, this project aimed to increase SSC for surgical infants in the neonatal intensive care unit (NICU). METHODS: A multidisciplinary working group composed of key NICU stakeholders instituted a needs assessment querying perceptions and concerns about SSC. Based on survey results, multiple system level interventions were implemented. Data for surgical infants receiving SSC during hospitalization were tracked over time using the electronic health record. RESULTS: Overall, 315 infants requiring a surgical consult were admitted to the NICU in the first 12â¯months of the project. After six months, SSC rates in this group increased from 51% to 60.5% (pâ¯<â¯0.01) and were sustained for 12â¯months. After one year, nursing staff reporting that they were somewhat to very comfortable providing SSC for surgical infants increased from 44% to 75% (pâ¯=â¯0.001) and the percent of nurses providing SSC for a surgical infant increased from 12% to 37% (pâ¯=â¯0.001). Inadvertent extubation did not significantly increase after implementation of the QI project. CONCLUSIONS: Using QI methodology and multidisciplinary engagement, SSC was integrated safely into the routine care of surgical infants in the NICU. LEVEL OF EVIDENCE: Level V.

INTRODUCTION: As survival has improved in the Neonatal Intensive Care Unit (NICU), there has been a 10-fold increase in the proportion of infants requiring a tracheostomy. At our institution, we observed a wide variation in the duration of opioid use posttracheostomy from 6 to 148 days. We aimed to decrease the duration of opioid exposure in postoperative tracheostomy patients in the NICU from a baseline average of 24 days to 7 days by December 31, 2017. METHODS: We established a multidisciplinary team to develop change ideas to implement in 3 Plan-Do-Study-Act cycles that focused on enhanced care plan standardization and communication in patient care rounds with subsequent documentation in the medical record and the timely addition of dexmedetomidine to the postoperative care plan. RESULTS: Baseline population was from October 2014 to December 2016. The mean posttracheostomy opioid duration was 24.6 days (range, 6-148 days); neuromuscular blockade was 2.89 days (range, 0-9 days), and benzodiazepine exposure was 20.9 days (range, 1-114 days). Following our interventions, the mean duration of posttracheostomy opioid duration was 5.4 days (range, 4-21 days); neuromuscular blockade was 3.14 days (range, 1-5 days), benzodiazepine duration was 8.88 days (range, 4-25 days), and dexmedetomidine was 4.6 days (range, 0-32 days). CONCLUSIONS: We utilized quality improvement methodology to standardize posttracheostomy management and demonstrate that we could significantly reduce the duration of opioid and benzodiazepine use after tracheostomy with the timely addition of dexmedetomidine, a structured written daily care plan, and clarification of roles and responsibilities.
RESUMO
OBJECTIVE: This is a comprehensive study designed to evaluate the clinical usefulness of transcutaneous bilirubinometry (TcB) in very low birth weight (VLBW) newborns of African American (AA) descent. METHODS: TcB was conducted at the anterior superior iliac spine (ASIS), temporal region and sternum within 2 h of total serum bilirubin (TSB) measurements in newborns born at ≤32 weeks' gestation prospectively. Average (AVG) TcB levels were also calculated. The relationships between TSB and TcB levels were analyzed using non-parametric Spearman bivariate correlations, a Bland-Altman plot procedure and a decision tree (DT) analysis. RESULTS: One hundred newborns and 555 TSB data points were available. Eighty-nine percent of the newborns were AA. A significant correlation (P<0.0001) was observed between TSB and TcB values obtained at the ASIS (r=0.73), sternum (0.73), temporal region (0.61) and AVG (0.77). The Bland-Altman plot revealed a good agreement between AVG TcB values and TSB values. A DT analysis indicated that AVG TcB was also found to be the most significant predictor of TSB values in both the no phototherapy (PT) and biliblanket subgroups. CONCLUSION: TcB can be used reliably in VLBW AA newborns in the absence of overhead PT. The use of TcB in monitoring jaundice in VLBW newborns would help decrease the number of blood draws and cost of care.

UNLABELLED: We surveyed neonatal leadership at 46 US children's hospitals via web-based survey to identify local preferences and concerns regarding indomethacin prophylaxis, nonsteroidal anti-inflammatory drug (NSAID) treatment, and patent ductus arteriosus (PDA) ligation. We received a 100 % survey response (N = 46). Practice guidelines for prophylactic indomethacin were reported at 28 % of NICUs, for NSAID treatment of PDA at 39 % and for surgical ligation at 27 %. Respondents noted intra-institutional practice variation for indomethacin prophylaxis (33 %), NSAID treatment (70 %), and PDA ligation (73 %). The majority of institutions did not prescribe indomethacin prophylaxis (72 %). For PDA treatment, indomethacin was preferred over ibuprofen (80 %). We validated our survey results via comparison with billing data as documented in the Pediatric Health Information System (PHIS) database, finding that survey responses directly correlated with local billing data (p < 0.0001). At institutions that did not typically administer NSAIDs for PDA closure or surgical PDA ligation, a lack of evidence for their effectiveness in improving long-term outcomes and the risk of treatment-associated adverse effects were the most often cited reasons. CONCLUSION: No consensus exists among providers at US children's hospitals regarding prophylactic indomethacin, NSAID treatment, or PDA ligation. Lack of evidence and safety concerns play a prominent role. WHAT IS KNOWN: ⢠NSAIDs and surgical PDA ligation are efficacious in preventing intraventricular hemorrhage (IVH) and closing PDA in preterm infants, but have not been shown to improve long-term respiratory, neurodevelopmental, or mortality outcomes. What is New: ⢠Practice preferences for indomethacin prophylaxis, NSAID, and surgical PDA treatment vary both among and within institutions. Lack of treatment effectiveness and the risk of adverse effects are major concerns.

OBJECTIVE: The Apgar score has been shown to have utility in predicting mortality in the extremely preterm infant in delivery hospital populations, where most mortality occurs within 12 hours of birth. We tested the hypothesis that the 5 minute Apgar score would remain associated with mortality in extremely preterm infants after transfer from the delivery hospital to an all referral neonatal intensive care unit at an average age of 10 days. STUDY DESIGN: A retrospective analysis of 454 infants born at < 27 weeks gestation. RESULTS: The median Apgar score was 3 at 1 minute (interquartile range [IQR] 2-6) and 6 at 5 minutes (IQR 4-7). The Apgar score increased from 1 to 5 minutes by 2.0 ± 1.7 (p < 0.001). In logistic regression modeling, an Apgar score of < 5 at 5 minutes was associated with an increased mortality (odds ratio 1.76 [95% confidence interval 1.06-2.94], p < 0.05), but not morbidities. CONCLUSION: Infants born at < 27 weeks gestation admitted to an all referral children's hospital at a mean age of 10 days with a 5 minute Apgar < 5 are at an increased risk of mortality. Our findings continue to support the importance of the Apgar score given at delivery even in the extremely preterm infant referred to a nondelivery children's hospital.

BACKGROUND: Proton magnetic resonance spectroscopy can be used to assess brain integrity and maturation with age. OBJECTIVE: To compare regional cerebral magnetic resonance spectroscopy metabolite ratios in extremely low birth weight and healthy term control infants measured at term-equivalent age and to evaluate association between magnetic resonance spectroscopy metabolites and cognitive and language development at 18-22 months' corrected age. METHODS: Single-voxel point-resolved spectroscopy sequence was performed in a prospective cohort of 43 infants. Magnetic resonance spectroscopy metabolite ratios of N-acetylaspartate to choline-containing compounds and N-acetylaspartate to myo-inositiol in the hippocampus, cortex, and subventricular zone were associated with Bayley mental, cognitive, and language scores at 18-22 months' corrected age. RESULTS: The mean (±S.D.) gestation of the 31 extremely low birth weight population was 25 (±1.1) weeks and mean (±S.D.) birth weight was 749 (±133.9) g. Compared with healthy term control infants, extremely low birth weight infants exhibited consistently lower N-acetylaspartate-to-choline-containing compounds ratios in our three regions of interest, with differences reaching statistical significance for the subventricular zone and cortex regions. In multiple linear regression analyses, N-acetylaspartate-to-choline-containing compounds ratio in the subventricular zone, N-acetylaspartate-to-choline-containing compounds ratio in the cortex, and N-acetylaspartate-to-myo-inositiol ratio in the subventricular zone were significantly associated with Bayley mental scores at 18-22 months' corrected age. CONCLUSIONS: Magnetic resonance spectroscopy metabolite abnormalities at term-equivalent age appear to be significantly associated with cognitive and language development in extremely low birth weight infants.

OBJECTIVE: To compare the neurodevelopmental outcomes at 18-22 months' corrected age of extremely premature infants exposed to a complete course, an incomplete course or no dose of antenatal steroids (ANS). METHODS: Retrospective chart review of extremely premature (<28 weeks gestational age) neonates over a 3-year period. Neurodevelopmental assessment at 18-22 months' corrected age included a standardized neurologic examination and the Bayley Scales of Infant and Toddler development II or III. Intact survival was defined as survival without cerebral palsy (CP), blindness or deafness and mental developmental index (MDI)/cognitive score ≥85. Neurodevelopmental impairment (NDI) was defined as any of the following: moderate or severe CP, MDI/cognitive score <70, deafness or blindness. Patients were categorized into three groups: (A) no ANS; (B) incomplete course and (C) complete course of ANS. RESULTS: Outcome data were available for 134 (88%) patients of our cohort (n = 153). Severe intraventricular hemorrhage (IVH) was significantly lower and intact survival was higher in the complete ANS group (p < 0.01). On logistic regression, with gestational age, gender, maternal insurance and ANS exposure as covariates, an incomplete (versus complete) course of ANS (p = 0.006) and gestational age were significantly associated with lower intact survival at 18-22 months.: CONCLUSIONS: A complete course of ANS was associated with an increased likelihood of intact survival at a corrected age of 18-22 months among extremely premature infants, compared with an incomplete course. Follow-up studies should account for the differential benefit of complete versus incomplete course of ANS administration.

We delineate the natural history of a right-to-left or bidirectional (RL/BD) patent ductus arteriosus (PDA) in preterm infants and compare outcomes of an RL/BD and a left-to-right (LR) ductal shunt. We performed a retrospective chart review of preterm infants (< 32 weeks), who, between 2 and 30 days of age, had an RL/BD PDA > 1.5 mm (study group; N = 74) or an LR PDA (N = 87) on echocardiogram (ECHO). In the study group, 27% of infants who were of significantly lower gestational age and birth weight had a "prolonged" RL/BD PDA on two or more ECHOs. Infants with RL/BD PDA required significantly greater surfactant (98.6% versus 94.2%) and less PDA therapy (27% versus 92%) and had higher mortality (48.6% versus 21.8%) compared with those with LR PDA. On regression analysis, lower gestation (odds ratio [OR] 1.45; 95% confidence interval [CI]: 1.15 to 1.83) and RL/BD PDA (OR 4.74; 95% CI: 2.18 to 10.3) were significantly associated with mortality. The independent association between an RL/BD PDA shunt and mortality warrants further investigation. Insights into the etiology of pulmonary hypertension may optimize outcomes in this population.
