Objective: The aim of this study was to compare outcomes of infants pre and post initiation of a feeding protocol providing an exclusive human milk–based diet (HUM).Materials and Methods: In a multicenter retrospective cohort study, infants with a birth weight <1,250 g who received a bovine-based diet (BOV) of mother's own milk fortified with bovine fortifier and/or preterm formula were compared to infants who received a newly introduced HUM feeding protocol. Infants were excluded if they had major congenital anomalies or died in the first 12 hours of life. Data were collected 2–3 years prior to and after introduction of an exclusive HUM diet. Primary outcomes were necrotizing enterocolitis (NEC) and mortality. Secondary outcomes included late-onset sepsis, retinopathy of prematurity (ROP), and bronchopulmonary dysplasia (BPD).Results: A total of 1,587 infants were included from four centers in Texas, Illinois, Florida, and California. There were no differences in baseline demographics or growth of infants. The HUM group had significantly lower incidence of proven NEC (16.7% versus 6.9%, p < 0.00001), mortality (17.2% versus 13.6%, p = 0.04), late-onset sepsis (30.3% versus 19.0%, p < 0.00001), ROP (9% versus 5.2%, p = 0.003), and BPD (56.3% versus 47.7%, p = 0.0015) compared with the BOV group.Conclusions: Extremely premature infants who received an exclusive HUM diet had a significantly lower incidence of NEC and mortality. The HUM group also had a reduction in late-onset sepsis, BPD, and ROP. This multicenter study further emphasizes the many benefits of an exclusive HUM diet, and demonstrates multiple improved outcomes after implementation of such a feeding protocol.

Objective: The purpose of this study was to evaluate the demographic and treatment characteristics of neonates (X37 weeks' estimated gestational age) who were admitted to a neonatal intensive care unit (NICU) for a diagnosis of meconium aspiration syndrome (MAS) during the years 1997 to 2007. The goals in studying this group of neonates were to better estimate the magnitude of abnormal outcomes and to determine the proportion of these infants exposed to specific therapeutic interventions.Study Design: Retrospective review of an administrative de-identified data set.Result: A total of 415 772 neonates formed the starting data set and 162 075 (39%) were X37 weeks. Of the 162 075 term neonates, 7518 (1.8% of all neonates and 4.6% of term NICU admissions) had an admission diagnosis of MAS. In the 7518 neonates, the following outcomes were observed: 6124 (81.5%) were discharged home; 679 (9%) were acutely transferred to a higher level of intensive care; 416 (5.5%) were transferred to another clinical service within the hospital; 178 (2.4%) were transferred to another NICU for convalescent care and 88 (1.2%) died. There were 33 (0.4%) who did not have data on outcome at discharge. During the period between 2002 and 2005, acute transfer rates decreased (12.4 to 9%) and the reported rate for death remained relatively constant between 0.9 and 1.5%. There were 107 (1.4%) neonates who were treated (n ¼ 61) with, or transferred, for extracorporeal membrane oxygenation (ECMO) (n ¼ 46). Three of the sixty-one neonates (4.9%) who were treated with ECMO died. Conclusion:Term neonates who are admitted with a diagnosis of MAS continue to represent a high-risk population with significant morbidity, and they often require intensive therapies.

WHAT'S KNOWN ON THIS SUBJECT: Quality-improvement techniques are increasingly effective as they move from passive dissemination to interactive techniques between those authoring practice change packages and their audiences. However, resource constraints and the many potential topics mitigate against prescribing intense collaboratives for every topic. WHAT THIS STUDY ADDS:Efficient progress in decreasing neonatal nosocomial infection rates can be achieved when statewide quality-improvement collaboratives using structured interventions ("toolkits") are augmented with brief interactions that introduce, orient, and motivate potential users. abstract 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-qualityimprovement 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 qualityimprovement 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.

Nosocomial sepsis is a serious problem for neonates who are admitted for intensive care. As it is associated with increases in mortality, morbidity, and prolonged length of hospital stay, both the human and fiscal costs of these infections are high. Although the rate of nosocomial sepsis increases with the degree of both prematurity and low birth weight, no specific lab test has been shown to be very useful in improving our ability to predict who has a "real" blood-stream infection and, therefore, who needs to be treated with a full course of antibiotics. As a result, antibiotic use is double the rate of "proven" sepsis and we are facilitating the growth of resistant organisms in the neonatal intensive care unit. The purpose of this article is to review the topic of nosocomial infections in neonates.
