RESUMO

AIM: To assess student nurses understanding and skills in the application of antimicrobial stewardship knowledge to practice. DESIGN: Quantitative. METHODS: Cross-sectional survey. RESULTS: Five hundred and twenty three student nurses responded across 23 UK universities. Although students felt prepared in competencies in infection prevention and control, patient-centred care and interprofessional collaborative practice, they felt less prepared in competencies in which microbiological knowledge, prescribing and its effect on antimicrobial stewardship is required. Problem-based learning, activities in the clinical setting and face-to-face teaching were identified as the preferred modes of education delivery. Those who had shared antimicrobial stewardship teaching with students from other professions reported the benefits to include a broader understanding of antimicrobial stewardship, an understanding of the roles of others in antimicrobial stewardship and improved interprofessional working. CONCLUSION: There are gaps in student nurses' knowledge of the basic sciences associated with the antimicrobial stewardship activities in which nurses are involved, and a need to strengthen knowledge in pre-registration nurse education programmes pertaining to antimicrobial management, specifically microbiology and antimicrobial regimes and effects on antimicrobial stewardship. Infection prevention and control, patient-centred care and interprofessional collaborative practice are areas of antimicrobial stewardship in which student nurses feel prepared. Interprofessional education would help nurses and other members of the antimicrobial stewardship team clarify the role nurses can play in antimicrobial stewardship and therefore maximize their contribution to antimicrobial stewardship and antimicrobial management. IMPLICATIONS FOR THE PROFESSION: There is a need to strengthen knowledge from the basic sciences, specifically pertaining to antimicrobial management, in pre-registration nurse education programmes. PATIENT OR PUBLIC CONTRIBUTION: No patient or public contribution. IMPACT: What Problem Did the Study Address? Nurses must protect health through understanding and applying antimicrobial stewardship knowledge and skills (Nursing and Midwifery Council 2018); however, there is no research available that has investigated nurses understanding and skills of the basic sciences associated with the antimicrobial stewardship activities in which they are involved. What Were the Main Findings? There are gaps in student nurses' knowledge of the basic sciences (specifically microbiology and prescribing) associated with the antimicrobial stewardship activities in which nurses are involved. Problem-based learning, and activities in the clinical setting, were reported as useful teaching methods, whereas online learning, was seen as less useful. Where and on Whom Will the Research Have an Impact? Pre-registration nurse education programmes. REPORTING METHOD: The relevant reporting method has been adhered to, that is, STROBE.

RESUMO

Amyloid-ß (Aß) and hyper-phosphorylated tau are key hallmarks of Alzheimer's disease (AD), with an accumulation of both proteins linked to hippocampal synaptic dysfunction. Recent evidence indicates that Aß drives mis-localisation of tau from axons to synapses, resulting in AMPA receptor (AMPAR) internalisation and impaired excitatory synaptic function. These tau-driven synaptic impairments are thought to underlie the cognitive deficits in AD. Consequently, limiting the synapto-toxic effects of tau may prevent AD-related cognitive deficits. Increasing evidence links leptin dysfunction with higher AD risk, and numerous studies have identified neuroprotective properties of leptin in AD models of Aß-induced toxicity. However, it is unclear if leptin protects against tau-related synaptic dysfunction. Here we show that Aß1-42 significantly increases dendritic and synaptic levels of tau and p-tau in hippocampal neurons, and these effects were blocked by leptin. In accordance with GSK-3ß being involved in tau phosphorylation, the protective effects of leptin involve PI 3-kinase (PI3K) activation and inhibition of GSK-3ß. Aß1-42 -driven synaptic targeting of tau was associated with the removal of GluA1-containing AMPARs from synapses, which was also inhibited by leptin-driven inhibition of GSK-3ß. Direct application of oligomeric tau to hippocampal neurons caused internalisation of GluA1-containing AMPARs and this effect was blocked by prior application of leptin. Similarly, leptin prevented the ability of tau to block induction of activity-dependent long-term potentiation (LTP) at hippocampal SC-CA1 synapses. These findings increase our understanding of the neuroprotective actions of leptin in the early pre-clinical stages of AD and further validate the leptin system as a therapeutic target in AD.

RESUMO

OBJECTIVE: To quantify outcomes and analyze factors predictive of morbidity and mortality in infants with gastroschisis. STUDY DESIGN: Clinical data regarding neonates with gastroschisis born between 2009 and 2014 were prospectively collected at 175 North American centers. Multivariate regression was used to assess risk factors for mortality and length of stay (LOS). RESULTS: Gastroschisis was diagnosed in 4420 neonates with median birth weight 2410 g (IQR 2105-2747). Survival (discharge home or alive in hospital at 1 year) was 97.8% with a 37 day median LOS (IQR 27-59). Sepsis, defined by positive blood or cerebrospinal fluid culture, was the only significant independent predictor of mortality (P = .04). Significant independent determinants of LOS and the percentage of neonates affected were as follows: bowel resection (9.8%, P < .0001), sepsis (8.6%, P < .0001), presence of other congenital anomalies (7.6%, including 5.8% with intestinal atresias, P < .0001), necrotizing enterocolitis (4.5%, P < .0001), and small for gestational age (37.3%, P = .0006). Abdominal surgery in addition to gastroschisis repair occurred in 22.3%, with 6.4% receiving gastrostomy or jejunostomy tubes and 6.3% requiring ostomy creation. At discharge, 57.0% were less than the 10th percentile weight for age. The mode of delivery (52.4% cesarean delivery) was not associated with any differences in outcome. CONCLUSIONS: Although neonates with gastroschisis have excellent overall survival they remain at risk for death from sepsis, prolonged hospitalization, multiple abdominal operations, and malnutrition at discharge. Outcomes appear unaffected by the use of cesarean delivery. Further opportunities for quality improvement include sepsis prevention and enhanced nutritional support.

RESUMO

OBJECTIVE: To quantify the association between necrotizing enterocolitis (NEC) and neurodevelopmental disability (NDI) in extremely low birth weight (ELBW) infants with intraventricular hemorrhage (IVH). STUDY DESIGN: ELBW survivors born 2011-2017 and evaluated at 16-26 months corrected age in the Vermont Oxford Network (VON) ELBW Follow-Up Project were included. Logistic regression determined the adjusted relative risk (aRR) of severe NDI in medical or surgical NEC compared to no NEC, stratified by severity of IVH. RESULTS: Follow-up evaluation occurred in 5870 ELBW survivors. Compared to no NEC, medical NEC had no impact on NDI, regardless of IVH status. Surgical NEC increased risk of NDI in patients with no IVH (aRR 1.69; 95% CI 1.36-2.09), mild IVH (aRR 1.36;0.97-1.92), and severe IVH (aRR 1.35;1.13-1.60). CONCLUSIONS: ELBW infants with surgical NEC carry increased risk of neurodevelopmental disability within each IVH severity stratum. These data describe the additive insult of surgical NEC and IVH on neurodevelopment, informing prognostic discussions and highlighting the need for preventative interventions.

RESUMO

BACKGROUND AND OBJECTIVE: In 2019, Pennsylvania launched a Children's Development Account (CDA) program that invests $100 in an education savings account for every child born in the state. However, as of 2021, only 10.6% of families claimed the investment. Low-income communities may stand to benefit most from educational investments, but few studies have assessed barriers and facilitators of uptake in these communities. We sought to examine low-income caregivers' perceptions of and barriers and facilitators to participation in a statewide CDA program and their receptivity to clinic-based financial counseling through a medical financial partnership. METHODS: We surveyed 100 caregivers of Medicaid-insured children from 2 primary care practices serving a predominantly low-income community. From these 100, we purposively sampled 30 caregivers for follow-up interviews. RESULTS: The 100 survey participants were predominantly female (83%), Black or African American (92%), and non-Hispanic or Latino (93%). Twenty-nine percent of survey participants were aware of the CDA program, 4% had enrolled, and 64% were interested in clinic-based financial counseling. In interviews, caregivers identified several barriers to and facilitators of engagement in the CDA program. They also identified several strategies to boost engagement, including simplifying registration, providing additional and personalized program information, expanding the investment amount, and providing clinic- and community-based outreach. CONCLUSIONS: Low-income caregivers identified several barriers to enrollment in a statewide CDA program and strategies to boost enrollment, including clinic-based financial counseling. Future research should examine the effectiveness, cost-effectiveness, and long-term financial and health consequences of clinic-based financial services for low-income families.

RESUMO

BACKGROUND: Necrotizing enterocolitis (NEC) and spontaneous intestinal perforation (SIP) affect 6-8% of extremely low birth weight (ELBW) infants. SIP has lower mortality than NEC, but with similar short-term morbidity in length of stay, growth failure, and supplemental oxygen requirements. Comparative long-term neurodevelopmental outcomes have not been clarified. METHODS: Data were prospectively collected from 59 North American neonatal units, regarding ELBW infants (401-1000 g or 22-27 weeks gestational age) born between 2011 and 2018 and evaluated again at 16-26 months corrected age. Outcomes were collected from infants with laparotomy-confirmed NEC, laparotomy-confirmed SIP, and those without NEC or SIP. The primary outcome was severe neurodevelopmental disability. Secondary outcomes were weight <10th percentile, medical readmission, post-discharge surgery and medical support at home. Adjusted risk ratios (ARR) were calculated. RESULTS: Of 13,673 ELBW infants, 6391 (47%) were followed including 93 of 232 (40%) with NEC and 100 of 235 (42%) with SIP. There were no statistically significant differences in adjusted risk of any outcomes when directly comparing NEC to SIP (ARR 2.35; 95% CI 0.89, 6.26). However, infants with NEC had greater risk of severe neurodevelopmental disability (ARR 1.43; 1.09-1.86), rehospitalization (ARR 1.46; 1.17-1.82), and post-discharge surgery (ARR 1.82; 1.48-2.23) compared to infants without NEC or SIP. Infants with SIP only had greater risk of post-discharge surgery (ARR 1.64; 1.34-2.00) compared to infants without NEC or SIP. CONCLUSIONS: ELBW infants with NEC had significantly increased risk of severe neurodevelopmental disability and post-discharge healthcare needs, consistent with prior literature. We now know infants with SIP also have increased healthcare needs. LEVELS OF EVIDENCE: Level II.

RESUMO

BACKGROUND: Limited data exists regarding the mortality of very low birth weight (VLBW) neonates with congenital diaphragmatic hernia (CDH). This study aims to quantify and determine predictors of mortality in VLBW neonates with CDH. METHODS: This analysis of 829 U.S. NICUs included VLBW [birth weight ≤1500g] neonates, born 2011-2021 with and without CDH. The primary outcome was in-hospital mortality. A generalized estimating equation regression model determined the adjusted risk ratio (ARR) of mortality. RESULTS: Of 426,140 VLBW neonates, 535 had CDH. In neonates with CDH, 48.4% had an additional congenital anomaly vs 5.5% without. In-hospital mortality for neonates with CDH was 70.4% vs 12.6% without. Of those with CDH, 73.3% died by day of life 3. Of VLBW neonates with CDH, 38% were repaired. A subgroup analysis was performed on 60% of VLBW neonates who underwent delivery room intubation or mechanical ventilation, as an indicator of active treatment. Mortality in this group was 62.7% for neonates with CDH vs 16.4% without. Higher Apgars at 1 min and repair of CDH were associated with lower mortality (ARR 0.91; 95%CI 0.87,0.96 and ARR 0.28; 0.21,0.39). The presence of additional congenital anomalies was associated with higher mortality (ARR 1.14; 1.01,1.30). CONCLUSION: These benchmark data reveal that VLBW neonates with CDH have an extremely high mortality. Almost half of the cohort have an additional congenital anomaly which significantly increases the risk of death. This study may be utilized by providers and families to better understand the guarded prognosis of VLBW neonates with CDH. TYPE OF STUDY: Level II. LEVEL OF EVIDENCE: Level II.

RESUMO

OBJECTIVE: Describe the frequency of best practice behaviors during NICU provider and nursing shift-to-shift handoffs and identify strengths and opportunities for improvement. STUDY DESIGN: Observational study of handoff characteristics among 40 centers participating in a learning collaborative over a 10-month period. Data were gathered using a handoff audit tool that outlined best practices. Comparisons of behaviors between nurse-to-nurse and provider-to-provider handoffs were made where appropriate. RESULTS: Overall, 946 audits of shift-to-shift handoffs were analyzed. While many behaviors were demonstrated reliably, differences between nurse-to-nurse vs provider-to-provider handoffs were noted. Families were present for 5.9% of handoffs and, among those who were present, 48.2% participated by contributing information, asking questions, and sharing goals. CONCLUSIONS: Observation and measurement of handoff behaviors can be used to identify opportunities to improve handoff communication, family participation, and human factors that support handoff. Auditing handoffs is feasible and necessary to improve these critical transitions in infants' care.

RESUMO

OBJECTIVE: To evaluate the impact of necrotizing enterocolitis (NEC) on mortality in very low birth weight (VLBW) infants with intraventricular hemorrhage (IVH). STUDY DESIGN: Data were collected on VLBW infants born 2014-2018 at Vermont Oxford Network (VON) centers. NEC and IVH were categorized by severity. Adjusted risk ratios (ARR) for in-hospital mortality were calculated. RESULTS: This study included 187 187 VLBW infants. Both medical and surgical NEC increased mortality risk compared to those without NEC. Stratification by IVH severity modified this effect (no IVH: ARR 3.04 (95%CI 2.74-3.38) for medical NEC and 4.17 (3.84-4.52) for surgical NEC; mild IVH: ARR 2.14 (1.88-2.44) for medical NEC and 2.49 (2.24-2.78) for surgical NEC; severe IVH: ARR 1.14 (1.03-1.26) for medical NEC and 1.10 (1.02-1.18) for surgical NEC). CONCLUSION: The relative impact of NEC on mortality decreased as IVH severity increased. Given the frequent coexistence of NEC and IVH, these data inform multidisciplinary management of these complex patients.

RESUMO

OBJECTIVE: This study aims to quantify mortality rates and hospital lengths of stay (LOS) in neonates with esophageal atresia and tracheoesophageal fistula (EA/TEF), and to characterize the effects of birth weight (BW) and associated congenital anomalies upon these. METHODS: Data regarding patients with EA/TEF were prospectively collected (2013-2019) at 298 North American centers. The primary outcome was mortality and secondary outcome was LOS.  Risk factors affecting mortality and LOS were assessed. RESULTS: EA/TEF was diagnosed in 3290 infants with a median BW of 2476 g (IQR 1897,2970). In-hospital mortality was 12.7%. Mortality was inversely correlated with BW. After adjustment, the risk of mortality decreased by approximately 11% with every 100 g increase in BW. A significant congenital anomaly other than EA/TEF was diagnosed in 37.9% of patients. Risk of mortality increased in patients with associated congenital anomalies, most notably in those with a severe cardiac anomaly. Lower BW was associated with an increased mean LOS among survivors. Similar to mortality risk, additional anomalies were associated with prolonged LOS. CONCLUSIONS: This study demonstrates an in-hospital mortality of over 10%. Both increased mortality and prolonged LOS are highly associated with lower birth weight and the presence of concomitant congenital anomalies.

RESUMO

BACKGROUND: Differences in morbidities between spontaneous intestinal perforation (SIP) and necrotizing enterocolitis (NEC) are unknown. METHODS: Prospectively collected multicenter data regarding very low birth weight (VLBW) infants 2015-2019 were analyzed. Diagnosis of SIP or NEC was laparotomy-confirmed in all patients. Multivariable regression modeling was used to assess adjusted length of stay (LOS; primary outcome) and adjusted risk ratios (ARR) for weight <10th percentile at discharge, and supplemental oxygen requirement at discharge. RESULTS: Of 201,300 VLBW infants at 790 hospitals, 1523 had SIP and 2601 had NEC. Adjusted LOS was similar for SIP and NEC (92 vs 88 days, p = 0.08561), but significantly higher than seen without SIP or NEC (68 days, p<0.0001). The risk of growth morbidity at discharge was similar between SIP and NEC (74.2% vs 75.3%; ARR:1.00;0.94,1.06), but higher than infants without SIP or NEC (47.7%; ARR:0.50;0.47,0.53). Infants with NEC were less likely to require supplemental oxygen at discharge than infants with SIP (24.4% vs 34.9%; ARR:0.80; 0.71,0.89). CONCLUSIONS: Although mortality is known to be lower in VLBW infants with SIP than NEC, this study highlights the similarly high morbidity experienced by both groups of infants. These benchmark data can help align counseling of families with expected outcomes. LEVEL OF EVIDENCE: Level II. TYPE OF STUDY: Prognosis study (Cohort Study).

RESUMO

OBJECTIVE: The COVID-19 pandemic has altered the delivery of follow-up care for high-risk infants. We performed an audit to characterize programmatic responses in a quality improvement network. STUDY DESIGN: We audited 43 North American-based follow-up programs of the Vermont Oxford Network Extremely Low Birth Weight Follow-up Study Group in October, 2020. Our electronic survey included yes/no, agree/disagree, and free text response items. RESULT: The response rate was 67.4%. Most programs altered capacity and the timing, frequency, or content of clinical assessments. Most perceived practice changes compromised their ability to ascertain infants' medical and developmental needs. There was a rapid uptake of telemedicine services. Despite challenges with implementation, many endorsed improved connectedness with families. CONCLUSION: Programs adapted rapidly to meet the needs of high-risk infants during the pandemic. Clinical operations, assessment procedures, and quality metrics will also need to evolve. Quality improvement study group collaboratives are well-positioned to coordinate such work.

RESUMO

Using data from a U.S. clinical safety trial of tenofovir gel, a candidate microbicide, we explored the intersection of sexual pleasure and vaginal lubrication to understand whether and under what circumstances women would use a microbicide gel covertly with primary partners. This study question emerged from acceptability research in diverse settings showing that even though future microbicides are extolled as a disease prevention method that women could use without disclosing to their partners, many women assert they would inform their primary partner. Participants (N = 84), stratified by HIV-status and sexual activity (active vs. abstinent), applied the gel intra-vaginally for 14 days. At completion, quantitative acceptability data were obtained via questionnaire (N = 79) and qualitative data via small group discussions (N = 15 groups, 40 women). Quantitatively, 71% preferred a microbicide that could not be noticed by a sex partner and 86% experienced greater vaginal lubrication with daily use. Based on our analysis of the qualitative data, we suggest that women's perception that their primary partners would notice a microbicide gel is a more important reason for their caution regarding covert use than may previously have been recognized. Our findings also showed that women's assessment of the possibility of discreet, if not covert, use was strongly related to their perception of how a microbicide's added vaginal lubrication would influence their own and their partner's pleasure, as well as their partner's experience of his sexual performance. A microbicide that increases pleasure for both partners could potentially be used without engendering opposition from primary partners.

RESUMO

OBJECTIVE: Assess practices supporting care transitions for infants and families in the neonatal intensive care unit (NICU) using a model of four key drivers: communication, teamwork, family integration, and standardization. STUDY DESIGN: Single-day audit among NICUs in the Vermont Oxford Network Critical Transitions collaborative addressing policies and practices supporting the four key drivers during admission, discharge, shift-to-shift handoffs, within hospital transfers, and select changes in clinical status. RESULTS: Among 95 NICUs, the median hospital rate of audited policies in place addressing the four key drivers were 47% (inter-quartile range (IQR) 35-65%) for communication, 67% (IQR 33-83%) for teamwork, 50% (IQR 33-61%) for family integration, and 70% (IQR 56-85%) for standardization. Of the 2462 infants included, 1066 (43%) experienced ≥1 specified transition during the week prior to the audit. CONCLUSIONS: We identified opportunities for improving NICU transitions in areas of communication, teamwork, family integration, and standardization.

RESUMO

OBJECTIVE: We sought to describe changes in the incidence and mortality of necrotizing enterocolitis (NEC) and associated surgical management strategies for very low birth weight (VLBW) infants. METHODS: Data were prospectively collected on VLBW infants (≤1500 g or < 29 weeks) born 2006 to 2017 and admitted to 820 U.S. centers. NEC was defined by the presence of at least one clinical and one radiographic finding. Trends analyses were performed to assess changes in incidence and mortality over time. RESULTS: Of 473,895 VLBW infants, 36,130 (7.6%) were diagnosed with NEC, of which 21,051 (58.3%) had medical NEC and 15,079 (41.7%) had surgical NEC. Medical NEC decreased from 5.3% to 3.0% (p < 0.0001). Surgical NEC decreased from 3.4% to 3.1% (p = 0.06). Medical NEC mortality decreased from 20.7% to 16.8% (p = 0.003), while surgical NEC mortality decreased from 36.6% to 31.6% (p < 0.0001). In the surgical cohort, the use of primary peritoneal drainage (PPD) versus initial laparotomy rose from 23.2% to 46.8%. CONCLUSION: The incidence and mortality of both medical and surgical NEC have decreased over time. Changes in surgical management during this time period included the increased utilization of primary peritoneal drainage. TYPE OF STUDY: Prognosis study. LEVEL OF EVIDENCE: Level II.

RESUMO

OBJECTIVES: In this study, we benchmark outcomes and identify factors associated with tracheostomy placement in infants of very low birth weight (VLBW). METHODS: Data were prospectively collected on infants of VLBW (401-1500 g or gestational age of 22-29 weeks) born between 2006 and 2016 and admitted to 796 North American centers. Length of stay (LOS), mortality, associated surgical procedures, and comorbidities were assessed, and infants who received tracheostomy were compared with those who did not. Multivariable logistic regressions were performed to identify risk factors for tracheostomy placement and for mortality in those receiving tracheostomy. RESULTS: Of 458 624 infants of VLBW studied, 3442 (0.75%) received tracheostomy. Infants with tracheostomy had a median (interquartile range) LOS of 226 (168-304) days and a mortality rate of 18.8%, compared with 58 (39-86) days and 8.3% for infants without tracheostomy. Independent risk factors associated with tracheostomy placement included male sex, birth weight <1001 g, African American non-Hispanic maternal race, chronic lung disease (CLD), intraventricular hemorrhage, patent ductus arteriosus ligation, and congenital neurologic, cardiac, and chromosomal anomalies. Among infants who received tracheostomy, male sex, birth weight <751 g, CLD, and congenital anomalies were independent predictors of mortality. CONCLUSIONS: Infants of VLBW receiving tracheostomy had twice the risk of mortality and nearly 4 times the initial LOS of those without tracheostomy. CLD and congenital anomalies were the strongest predictors of tracheostomy placement and mortality. These benchmark data on tracheostomy in infants of VLBW should guide discussions with patient families and inform future studies and interventions.

RESUMO

While most studies of deterministic network growth have been of one- or two-case models, here a more diverse and comprehensive method of deterministic network evolution is presented. The range of observed behavior is classified and the underlying causes of the various types of growth are investigated. The potential for prediction of the different types of network growth is also examined. It is discovered that a wide variety of behavior can be produced by a simple evolutionary setup and that the networks resulting from this method of evolution warrant further study.

RESUMO

BACKGROUND: Gastroschisis, a surgical condition requiring complex interdisciplinary care, may benefit from treatment at higher volume centers. Recent studies on surgical volume and outcomes have conflicting findings. METHODS: Data were collected prospectively on newborns ≥1500 g with gastroschisis born 2009-2015, admitted to 159 US centers, and separated into terciles based on number of annual gastroschisis repairs. Infants transferred after gastroschisis repair were excluded. RESULTS: There were 4663 infants included: 307 from 53 low, 1201 from 55 medium, and 3155 from 51 high volume centers. Infants at high volume centers had higher rates of intestinal atresia (P = 0.04) and outborn status (P < 0.0001). Outborn infants (N = 1134) had higher rates of gastrostomy/jejunostomy placement (P < 0.001). Mortality was universally low (2.0% low, 2.4% medium, and 1.7% high; 2.0% outborn and 1.9% inborn). On multivariate analysis, mortality, sepsis rates, and length of stay did not differ by center volume. Outborn status was associated with longer length of stay (P = 0.001), not mortality or sepsis. CONCLUSION: Infant characteristics and management vary based on gastroschisis surgical volume and transfer status. Center volume and early transfers were not associated with mortality. Further investigation to identify subsets of gastroschisis infants who would benefit from care at higher volume centers is warranted. TYPE OF STUDY: Prognosis study. LEVEL OF EVIDENCE: Level II.

RESUMO

OBJECTIVES: To determine if NICU teams participating in a multicenter quality improvement (QI) collaborative achieve increased compliance with the Centers for Disease Control and Prevention (CDC) core elements for antibiotic stewardship and demonstrate reductions in antibiotic use (AU) among newborns. METHODS: From January 2016 to December 2017, multidisciplinary teams from 146 NICUs participated in Choosing Antibiotics Wisely, an Internet-based national QI collaborative conducted by the Vermont Oxford Network consisting of interactive Web sessions, a series of 4 point-prevalence audits, and expert coaching designed to help teams test and implement the CDC core elements of antibiotic stewardship. The audits assessed unit-level adherence to the CDC core elements and collected patient-level data about AU. The AU rate was defined as the percentage of infants in the NICU receiving 1 or more antibiotics on the day of the audit. RESULTS: The percentage of NICUs implementing the CDC core elements increased in each of the 7 domains (leadership: 15.4%-68.8%; accountability: 54.5%-95%; drug expertise: 61.5%-85.1%; actions: 21.7%-72.3%; tracking: 14.7%-78%; reporting: 6.3%-17.7%; education: 32.9%-87.2%; P < .005 for all measures). The median AU rate decreased from 16.7% to 12.1% (P for trend < .0013), a 34% relative risk reduction. CONCLUSIONS: NICU teams participating in this QI collaborative increased adherence to the CDC core elements of antibiotic stewardship and achieved significant reductions in AU.
