The Relationship of Nosocomial Infection Reduction to Changes in Neonatal Intensive Care Unit Rates of Bronchopulmonary Dysplasia.

OBJECTIVE: To examine whether recent reductions in rates of nosocomial infection have contributed to changes in rates of bronchopulmonary dysplasia (BPD) in a population-based cohort. STUDY DESIGN: This was a retrospective, population-based cohort study that used the California Perinatal Quality Care Collaborative database from 2006 to 2013. Eligible infants included those less than 30 weeks' gestational age and less than 1500 g who survived to 3 days of life. Primary variables of interest were rates of nosocomial infections and BPD. Adjusted rates of nosocomial infections and BPD from a baseline period (2006-2010) were compared with a later period (2011-2013). The correlation of changes in rates across periods for both variables was assessed by hospital of care. RESULTS: A total of 22 967 infants from 129 hospitals were included in the study. From the first to second time period, the incidence of nosocomial infections declined from 24.7% to 15% and BPD declined from 35% to 30%. Adjusted hospital rates of BPD and nosocomial infections were correlated positively with a calculated 8% reduction of BPD rates attributable to reductions in nosocomial infections. CONCLUSIONS: Successful interventions to reduce rates of nosocomial infections may have a positive impact on other comorbidities such as BPD. The prevention of nosocomial infections should be viewed as a significant component in avoiding long-term neonatal morbidities.

Nosocomial infection reduction in VLBW infants with a statewide quality-improvement model.

OBJECTIVE: To evaluate the effectiveness of the California Perinatal Quality Care Collaborative quality-improvement model using a toolkit supplemented by workshops and Web casts in decreasing nosocomial infections in very low birth weight infants. DESIGN: This was a retrospective cohort study of continuous California Perinatal Quality Care Collaborative members' data during the years 2002-2006. The primary dependent variable was nosocomial infection, defined as a late bacterial or coagulase-negative staphylococcal infection diagnosed after the age of 3 days by positive blood/cerebro-spinal fluid culture(s) and clinical criteria. The primary independent variable of interest was voluntary attendance at the toolkit's introductory event, a direct indicator that at least 1 member of an NICU team had been personally exposed to the toolkit's features rather than being only notified of its availability. The intervention's effects were assessed using a multivariable logistic regression model that risk adjusted for selected demographic and clinical factors. RESULTS: During the study period, 7733 eligible very low birth weight infants were born in 27 quality-improvement participant hospitals and 4512 very low birth weight infants were born in 27 non-quality-improvement participant hospitals. For the entire cohort, the rate of nosocomial infection decreased from 16.9% in 2002 to 14.5% in 2006. For infants admitted to NICUs participating in at least 1 quality-improvement event, there was an associated decreased risk of nosocomial infection (odds ratio: 0.81 [95% confidence interval: 0.68-0.96]) compared with those admitted to nonparticipating hospitals. CONCLUSIONS: The structured intervention approach to quality improvement in the NICU setting, using a toolkit along with attendance at a workshop and/or Web cast, is an effective means by which to improve care outcomes.

Neonatal intensive care unit collaboration to decrease hospital-acquired bloodstream infections: from comparative performance reports to improvement networks.

This two-part article provides a general guide to thinking about data-driven clinical performance evaluation and describes two statewide improvement networks anchored in such comparisons. Part 1 examines key ideas for making fair comparisons among providers. Part 2 describes the development of a data-driven collaborative that aims to reduce central line associated bloodstream infections in neonatal ICUs across New York State, and a more mature collaborative in California that has already succeeded in reducing these infections; it provides sufficient detail and tools to be of practical help to others seeking to create such networks. The content illustrates concepts with broad applicability for pediatric quality improvement.

Promoting antenatal steroid use for fetal maturation: results from the California Perinatal Quality Care Collaborative.

OBJECTIVE: The California Perinatal Quality Care Collaborative (CPQCC) was formed to seek perinatal care improvements by creating a confidential multi-institutional database to identify topics for quality improvement (QI). We aimed to evaluate this approach by assessing antenatal steroid administration before preterm (24 to 33 weeks of gestation) delivery. We hypothesized that mean performance would improve and the number of centers performing below the lowest quartile of the baseline year would decrease. STUDY DESIGN: In 1998, a statewide QI cycle targeting antenatal steroid use was announced, calling for the evaluation of the 1998 baseline data, dissemination of recommended interventions using member-developed educational materials, and presentations to California neonatologists in 1999-2000. Postintervention data were assessed for the year 2001 and publicly released in 2003. A total of 25 centers voluntarily participated in the intervention. RESULTS: Antenatal steroid administration rate increased from 76% of 1524 infants in 1998 to 86% of 1475 infants in 2001 (P < .001). In 2001, 23 of 25 hospitals exceeded the 1998 lower-quartile cutoff point of 69.3%. CONCLUSIONS: Regional collaborations represent an effective strategy for improving the quality of perinatal care.

Cesarean delivery rates and neonatal morbidity in a low-risk population.

OBJECTIVE: To estimate the relationship between case-mix adjusted cesarean delivery rates and neonatal morbidity and mortality in infants born to low-risk mothers. METHODS: This retrospective cohort study used vital and administrative data for 748,604 California singletons born without congenital abnormalities in 1998-2000. A total of 282 institutions was classified as average-, low-, or high-cesarean delivery hospitals based on their cesarean delivery rate for mothers without a previous cesarean delivery, in labor at term, with no evidence of maternal, fetal, or placental complications. Neonatal mortality, diagnoses, and therapeutic interventions determined by International Classification of Diseases, 9th Revision, Clinical Modification codes, and neonatal length of stay were compared across these hospital groupings. RESULTS: Compared with average-cesarean delivery-rate hospitals, infants born to low-risk mothers at low-cesarean delivery hospitals had increased fetal hemorrhage, birth asphyxia, meconium aspiration syndrome, feeding problems, and electrolyte abnormalities (P <.02). Infused medication, pressors, transfusion for shock, mechanical ventilation, and length of stay were also increased (P <.001). This suggests that some infants born in low-cesarean delivery hospitals might have benefited from cesarean delivery. Infants delivered at high-cesarean delivery hospitals demonstrated increased fetal hemorrhage, asphyxia, birth trauma, electrolyte abnormalities, and use of mechanical ventilation (P <.001), suggesting that high cesarean delivery rates themselves are not protective. CONCLUSION: Neonatal morbidity is increased in infants born to low-risk women who deliver at both low- and high-cesarean delivery-rate hospitals. The quality of perinatal care should be assessed in these outlier hospitals. LEVEL OF EVIDENCE: III

Evaluation and development of potentially better practices to prevent neonatal nosocomial bacteremia.

OBJECTIVE: Six neonatal intensive care units (NICUs) that are members of the Vermont Oxford National Evidence-Based Quality Improvement Collaborative for Neonatology collaborated to reduce infection rates. There were 7 centers in the original focus group, but 1 center left the collaborative after 1 year. The objective of this study was to develop strategies to decrease nosocomial infection rates in NICUs. METHODS: The process included a comprehensive literature review, internal practice analyses, benchmark studies, and development of practical experience through rapid-cycle changes, subsequent analysis, and feedback. This process led to 3 summary statements on potentially better practices in handwashing, approach to nosocomial sepsis evaluations, and central venous catheter management. RESULTS: These statements provide a basis for an evidence-based approach to lowering neonatal intensive care unit nosocomial infection rates. CONCLUSIONS: The 2-year process also led to changes in the culture and habits of the institutions involved, which should in turn have long-term effects on other aspects of quality improvement.

Implementation of evidence-based potentially better practices to decrease nosocomial infections.

OBJECTIVE: Six neonatal intensive care units (NICUs) that are members of the Vermont Oxford National Evidence-Based Quality Improvement Collaborative for Neonatology collaborated to reduce infection rates. There were 7 centers in the original focus group, but 1 center left the collaborative after 1 year. Nosocomial infection is a significant area for improvement in most NICUs. METHODS: Six NICUs participating in the Vermont Oxford Network made clinical changes to address 3 areas of consensus: handwashing, line management, and accuracy of diagnosis. The summary statements were widely communicated. Review of the literature, internal assessments, and benchmarking visits all contributed to ideas for change. RESULTS: The principle outcome was the incidence of coagulase-negative staphylococcus bacteremia. There was an observed reduction from 24.6% in 1997 to 16.4% in 2000. CONCLUSIONS: The collaborative process for clinical quality improvement can result in effective practice changes.

Idiopathic neonatal giant cell hepatitis presenting with acute hepatic failure on postnatal day one.

We report a term male infant presenting on postnatal day 1 with fulminant hepatic failure. Described congenital infection, metabolic disorders, and cardiovascular etiologies of acute neonatal liver failure were assessed and eliminated. A liver biopsy on postnatal day 10 showed neonatal giant cell hepatitis (NGCH) with an unusual degree of fibrosis for this early postnatal age. NGCH is a clinical diagnosis of cholestatic disorders of unknown etiology in the newborn, and, to our knowledge, has not been previously associated with immediate neonatal hepatic failure. The giant cell transformation is a common response to a variety of insults and only rarely occurs beyond the neonatal period. Most cases present with cholestatic jaundice and varying degrees of coagulopathy, and, many, as in this case, show progressive resolution.
