Improving the quality of care for infants: a cluster randomized controlled trial

Antimicrobial utilisation patterns between 2013 and 2022 in Canadian neonates born at less than 33 weeks gestation: a retrospective cohort study

Background

Excessive antimicrobial exposure is associated with an increase in neonatal mortality, morbidities and adverse neurodevelopment. Canadian Neonatal Network has been promoting judicious antimicrobial use through the Evidence-based Practice for Improving Quality processes. Our objective was to evaluate the antimicrobial consumption among neonates in tertiary neonatal intensive care units (NICU) in Canada in the recent decade.

Methods

This is a retrospective cohort study including data from very preterm infants (born at <33 weeks gestational age) admitted to all NICUs in Canada between January 1, 2013, and December 31, 2022. Nationwide antimicrobial utilization rate (AUR) benchmarking started in 2016, and quality improvement initiatives were continued in the subsequent years to promote judicious use of antimicrobials across the network. AUR is defined as the number of days with ≥1 antimicrobial divided by the total patient days (PD). Culture-proven sepsis refers to a neonate with positive culture of pathogens in blood and/or cerebrospinal fluid. The outcomes were evaluated during pre- (2013-2017) and post-intervention periods (2018-2022). Interrupted time-series analysis was used, and comparison of AUR calculated per each 3-month time block and the slope changes were conducted across the pre- and post-intervention periods regarding total patients and subgroups.

Findings

A total of 41,253 infants were included, with 22,644 (55%) being male. The AUR was significantly lower among infants from the post- vs. those from the pre-intervention periods (152 vs. 184, p < 0.0001). Among 35,670 infants without culture-proven sepsis or necrotizing enterocolitis ≥ Stage 2, AUR was significantly lower in the post-intervention group vs. the pre-intervention group (110 vs. 136, p < 0.0001). Interrupted time-series showed significant reduction in AUR during both pre- and post-intervention periods among all infants with and without culture proven sepsis or necrotizing enterocolitis ≥ Stage 2 (all p < 0.0001), as well as those born at <29 weeks gestational age.

Interpretation

A comprehensive, network-wide quality improvement initiatives led to a significant and sustained reduction in antimicrobial use among preterm infants born at <33 weeks gestational age with and without culture-proven sepsis or necrotizing enterocolitis ≥ Stage 2.

Funding

This study was supported by the Canadian Institutes of Health Research Project Grant 2019 (201903PJT-420294-CA2-CAAA-245530), matched funding from the British Columbia Women's Health Foundation and start-up funding from the Women and Children's Health Research Institute, University of Alberta. The coordinating center in Toronto is funded by the Canadian Institutes of Health Research grant for the Canadian Preterm Birth Network (PBN 150642).

The role of QI collaboratives in neonatology

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.

Impact of comprehensive quality improvement program on outcomes in very-low-birth-weight infants: A cluster-randomized controlled trial in Japan

BACKGROUND

Differences in outcomes among neonatal intensive care units (NICUs) in Japan have been noted, prompting the need for quality improvement.

AIM

To assess a comprehensive quality improvement program on outcomes in very-low-birth-weight (VLBW) infants.

STUDY DESIGN

A cluster-randomized clinical trial.

SUBJECTS

Forty hospitals and VLBW infants born in 2012-2014 and admitted to those hospitals were study subjects.

OUTCOME MEASURES

The intervention group (IG) received a comprehensive quality improvement program involving clinical practice guidelines, educational outreach visits, workshops, opinion leader training, audits, and feedback. The control group (CG) was provided only with the guidelines. The primary outcome was survival without neurological impairment at three years of age.

RESULTS

IG consisted of 19 hospitals and 1735 infants, while CG included 21 hospitals and 1700 infants. There were no significant differences in gestational weeks, 29.1(26.9-31.3) vs. 29.1(26.7-31.1) or birth weights (g), 1054(789-1298) vs. 1084(810-1309) between the two groups. Both groups showed survival rates without neurological impairment of 67.2 % (1166) and 66.9 % (1137), respectively, without a significant difference. There was no significant difference in mortalities at NICU discharge between the groups, with rates of 4.0 % (70) and 4.2 % (72) respectively. Several clinically relevant improvements were observed in IG, including reduced rates of sepsis, adrenal insufficiency, transfusion for anemia, and a shorter interval to achieve full enteral feeding. However, these did not lead to improvements in the primary outcome.

CONCLUSION

The comprehensive quality improvement program to Japanese NICUs did not result in a significant improvement in survival without neurological impairment in VLBW infants.

Common Quality Improvement Methodologies Including the Model for Improvement, Lean, and Six Sigma

This article reviews several common quality improvement methodologies, including the Model for Improvement, Lean, and Six Sigma. We demonstrate how these methods are based on a similar improvement science foundation. We describe the tools used to understand problems in the context of systems and the mechanisms to learn and build knowledge, using specific examples from the neonatology and pediatric literature. We conclude with a discussion on the importance of the human side of change in quality improvement, including team formation and culture.

Parent-Integrated Interventions to Improve Language Development in Children Born Very Preterm

Neurodevelopmental challenges in children born very preterm are common and not improving. This study tested the feasibility of using Evidence-based Practice to Improve Quality (EPIQ), a proven quality improvement technique that incorporates scientific evidence to target improving language abilities in very preterm populations in 10 Canadian neonatal follow-up programs. Feasibility was defined as at least 70% of sites completing four intervention cycles and 75% of cycles meeting targeted aims. Systematic reviews were reviewed and performed, an online quality improvement educational tool was developed, multidisciplinary teams that included parents were created and trained, and sites provided virtual support to implement and audit locally at least four intervention cycles of approximately 6 months in duration. Eight of ten sites implemented at least four intervention cycles. Of the 48 cycles completed, audits showed 41 (85%) met their aim. Though COVID-19 was a barrier, parent involvement, champions, and institutional support facilitated success. EPIQ is a feasible quality improvement methodology to implement family-integrated evidence-informed interventions to support language interventions in neonatal follow-up programs. Further studies are required to identify potential benefits of service outcomes, patients, and families and to evaluate sustainability.

GloveCare: a pilot study in preparation for a cluster crossover randomized controlled trial of non-sterile glove-based care in preventing late-onset infection in the NICU

BACKGROUND

Late-onset infections (LOI) are a major cause of morbidity and mortality among patients in the neonatal intensive care unit (NICU). Gloving after hand hygiene may be a pragmatic approach to prevent infections that arise when healthcare workers' hands transmit pathogens to neonates.

OBJECTIVE

To determine the feasibility of conducting a multicenter, open-labeled randomized controlled trial (RCT) to determine whether a protocol that requires healthcare workers (HCWs) in a level 3 NICU to wear non-sterile gloves plus hand hygiene reduces the occurrence of a late-onset infection, compared to hand hygiene alone.

METHODS

In this single-center pilot study, we recruited neonates admitted to the McMaster Children's Hospital NICU from June 2017 to May 2018. The NICU was randomized to begin with the standard (control) arm for 6 months (June 2017 to Dec 2017), followed by the gloving (GloveCare) arm for 6 months (Jan 2018 to July 2018), with a 2-week washout period in-between to educate healthcare workers about gloving. We measured numerous feasibility outcomes including enrollment, event rate, and compliance with hand hygiene (Moment 1: before patient contact, Moment 2: before clean procedure, Moment 3: after body fluid contact, Moment 4: after patient contact) and gloving compliance.

RESULTS

We enrolled 750 neonates (390 Standard care, 360 GloveCare) and achieved 100% enrollment. We found higher hand hygiene compliance during the standard care arm compared to the GloveCare for all four moments of hand hygiene (Moment 1: 87% vs 79%, OR=1.86 (1.34, 2.59); Moment 2: OR=1.73 (1.00, 3.01); Moment 3: OR=1.11 (0.62, 1.98); Moment 4: OR=1.65 (1.27, 2.14)). We developed and validated a method to calculate glove compliance, which ranged from 48 to 85%, and was highest for moment 3 (doffing after a procedure or body fluid exposure risk). No adverse events were documented for patients or staff.

DISCUSSION

Reduction in hand hygiene compliance in the GloveCare arm presents a pragmatic challenge in ascertaining the effectiveness of gloving to prevent LOI. Most LOIs were non-sterile-site infections, which is considered a less patient-important or clinically relevant outcome compared to sterile-site LOI. Ensuring efficient collection and validation of hand hygiene and gloving data is imperative.

CONCLUSION

The pilot study demonstrated the feasibility of this intervention though modifications to improve hand hygiene compliance during GloveCare will be important prior to a multicenter cluster RCT to assess the efficacy of non-sterile glove-based care in preventing LOI in the NICU.

Advancements in neonatology through quality improvement

In the past 3 decades, quality improvement methodology has often been employed in medicine to improve patient outcomes. Neonatal medicine has seen an increase in publications using improvement science to ensure the application of potentially better practices to decrease complications and increase survival without major disability. This article reviews quality improvement studies that have impacted neonatal mortality and morbidity, as well as specific disease processes including bronchopulmonary dysplasia, intraventricular hemorrhage, necrotizing enterocolitis, and retinopathy of prematurity. Using improvement science, studies have substantially reduced neonatal mortality and the major complications of preterm birth.

The Trend in Costs of Tertiary-Level Neonatal Intensive Care for Neonates Born Preterm at 220/7-286/7 Weeks of Gestation from 2010 to 2019 in Canada

OBJECTIVE

To describe the trend in costs over 10 years for tertiary-level neonatal care of infants born 22^0/7-28^6/7 weeks of gestation during an ongoing Canadian national quality improvement project.

STUDY DESIGN

Clinical characteristics, outcomes, and third-party payor costs for the tertiary neonatal care of infants born 22^0/7-28^6/7 weeks of gestation between the years 2010 and 2019 were analyzed from the Canadian Neonatal Network database. Costs were estimated using resource use data from the Canadian Neonatal Network and cost inputs from hospitals, physician billing, and administrative databases in Ontario, Canada. Cost estimates were adjusted to 2017 Canadian dollars (CAD). A generalized linear mixed-effects model with gamma regression was used to estimate trends in costs.

RESULTS

Between 2010 and 2019, the number of infants born <24 weeks of gestation increased from 4.4% to 7.7%. The average length of stay increased from 68 days to 75 days. Unadjusted average ± SD total costs per neonate were $120 717 ± $93 062 CAD in 2010 and $132 774 ± $93 161 CAD in 2019. After adjustment for year, center, and gestation, total costs and length of stay increased significantly, by $13 612 CAD (P < .01) and 8.1 days (P < .01) over 10 years, respectively; whereas costs accounting for LOS remained stable.

CONCLUSIONS

The total costs and length of stay for infants 22^0/7-28^6/7 weeks of gestation have increased over the past decade in Canada during an ongoing national quality improvement initiative; however, there was an increase in the number and survival of neonates at the age of periviability.

Chinese Neonatal Network: a national protocol for collaborative research and quality improvement in neonatal care

INTRODUCTION

The objective of the Chinese Neonatal Network (CHNN) is to provide a platform for collaborative research, outcomes evaluation and quality improvement for preterm infants with gestational age less than 32 weeks in China. The CHNN is the first national neonatal network and has the largest geographically representative cohort from neonatal intensive care units (NICUs) in China.

METHODS AND ANALYSIS

Individual-level data from participating NICUs will be collected using a unique database developed by the CHNN on an ongoing basis from January 2019. Data will be prospectively collected from all infants <32 weeks gestation or <1500 g birth weight at 58 participating NICUs. Infant outcomes and inter-institutional variations in outcomes will be examined and used to inform quality improvement measures aimed at improving outcomes. Information about NICU environmental and human resource factors and processes of neonatal care will also be collected and analysed for association with outcomes. Clinical studies, including randomised controlled trials will be conducted using the CHNN data platform.

ETHICS AND DISSEMINATION

This study was approved by the ethics review board of Children's Hospital of Fudan University, which was recognised by all participating hospitals. Waiver of consent were granted at all sites. Only non-identifiable patient level data will be transmitted and only aggregate data will be reported in CHNN reports and publications.

Hemodynamic Quality Improvement Bundle to Reduce the Use of Inotropes in Extreme Preterm Neonates

BACKGROUND

We evaluated the effect of the quality improvement (QI) bundle on the rate of inotrope use and associated morbidities.

METHODS

We included inborn preterm neonates born at < 29 weeks admitted to level III NICU. We implemented a QI bundle focusing on the first 72 h from birth which included delayed cord clamping, avoidance of routine echocardiography, the addition of clinical criteria to the definition of hypotension, factoring iatrogenic causes of hypotension, and standardization of respiratory management. The rate of inotropes use was compared before and after implementing the care bundle. Incidence of cystic periventricular leukomalacia (cPVL) was used as a balancing measure.

RESULTS

QI bundle implementation was associated with significant reduction in overall use of inotropes (24 vs 7%, p < 0.001), dopamine (18 vs 5%, p < 0.001), and dobutamine (17 vs 4%, p < 0.001). Rate of acute brain injury decreased significantly: acute brain injury of any grade (34 vs 20%, p < 0.001) and severe brain injury (15 vs 6%, p < 0.001). There was no difference in the incidence of cPVL (0.8 vs 1.4%, p = 0.66). Associations remained significant after adjusting for confounding factors.

CONCLUSIONS

A quality improvement bundled approach resulted in a reduction in inotropes use and associated brain morbidities in premature babies.

Decreasing Trend in Incidence of Late Onset Culture Positive Bloodstream Infections but Not Late Onset Meningitis in Preterm Infants <33 Weeks Gestation in Canadian Neonatal Intensive Care Unit

INTRODUCTION

Recent studies reported decreased incidence of late onset sepsis in the neonatal intensive care unit (NICU), but it is unclear whether this is also true for late onset meningitis. Recent reports that both meningitis and intraventricular hemorrhage (IVH) are associated with systemic inflammation also raise questions about an association between the 2.

METHODS

All preterm infants <33 weeks gestational age admitted to CNN NICUs from 2010 to 2018 were included. We compared incidence trends of late onset culture positive bloodstream infection (CPBSI) and late onset meningitis, and examined the association of meningitis and IVH (exposure), after adjustment for potential confounders.

RESULTS

Of 36,573 infants included, 32,198 had no infection, 3,977 had only late onset CPBSI and 398 had late onset meningitis. There was significant decrease in incidence of late onset CPBSI (14%-10%; adjusted odds ratio (AOR) = 0.93; 95% confidence interval [CI] 0.92, 0.95) but not late onset meningitis (1.6%-1.2%; AOR = 0.98; 95% CI 0.94, 1.01). Compared to infants with no IVH grade 3 or above, infants with IVH grade 3, or above had higher odds of late onset meningitis versus no infection (AOR 4.16; 95% CI 3.17, 5.44), and higher odds of late onset meningitis versus late onset CPBSI (AOR 4.11; 95% CI 3.08, 5.50).

CONCLUSIONS

There was a decreasing trend of late onset CPBSI but not late onset meningitis. An association between late onset meningitis and IVH grade 3 or above was observed. Late onset CPBSI and meningitis may have different risk factors and require different prevention strategies.

Impact of a “Brain Protection Bundle” in Reducing Severe Intraventricular Hemorrhage in Preterm Infants <30 Weeks GA: A Retrospective Single Centre Study

Background: despite advances in perinatal care, periventricular/intraventricular hemorrhage (IVH) continues to remain high in neonatal intensive care units (NICUs) worldwide. Studies have demonstrated the benefits of implementing interventions during the antenatal period, stabilization after birth (golden hour management) and postnatally in the first 72 h to reduce the incidence of IVH. Objective: to compare the incidence of severe intraventricular hemorrhage (IVH ≥ Grade III) before and after implementation of a “brain protection bundle” in preterm infants <30 weeks GA. Study design: a pre- and post-implementation retrospective cohort study to compare the incidence of severe IVH following execution of a “brain protection bundle for the first 72 h from 2015 to 2018. Demographics, management practices at birth and in the NICU, cranial ultrasound results and short-term morbidities were compared. Results: a total of 189 and 215 infants were included in the pre- and post-implementation phase, respectively. No difference in the incidence of severe IVH (6.9% vs. 9.8%, p = 0.37) was observed on the first cranial scan performed after 72 h of age. Conclusion: the implementation of a “brain protection bundle” was not effective in reducing the incidence of severe IVH within the first 72 h of life in our centre.

Barriers and facilitators in the management of preoperative thirst of the burned patient in the light of Knowledge Translation

OBJECTIVE

To explore the perception of health care professionals about barriers and facilitators, and coping strategies for the implementation of the Thirst Management Model in the preoperative period of the burned patient.

METHOD

This is a qualitative study, anchored in the conceptual framework Knowledge Translation. The focus group technique was chosen for data collection, composed by eight key professionals, to identify barriers and facilitators in evidence implementation and to point out coping strategies for the critical nodes found. Thematic Content Analysis technique was used to evaluate the data.

RESULTS

Five categories emerged: Physical structure, environment and supplies; Particularities of the burned patient; Human Resources; Team attitude; Team training and education. Coping strategies were raised for each barrier identified.

CONCLUSION

The main barriers identified were found in the Human Resources and Team Attitude categories. The main facilitators were Particularities of the burned patient and Team training and education. The identification allowed planning coping strategies for critical nodes, providing support for scientific evidence in clinical practice.

Rationale, Methodological Quality, and Reporting of Cluster-Randomized Controlled Trials in Critical Care Medicine: A Systematic Review

OBJECTIVE

Compared with individual-patient randomized controlled trials, cluster randomized controlled trials have unique methodological and ethical considerations. We evaluated the rationale, methodological quality, and reporting of cluster randomized controlled trials in critical care studies.

DATA SOURCES

Systematic searches of Medline, Embase, and Cochrane Central Register were performed.

STUDY SELECTION

We included all cluster randomized controlled trials conducted in adult, pediatric, or neonatal critical care units from January 2005 to September 2019.

DATA EXTRACTION

Two reviewers independently screened citations, reviewed full texts, protocols, and supplements of potentially eligible studies, abstracted data, and assessed methodology of included studies.

DATA SYNTHESIS

From 1,902 citations, 59 cluster randomized controlled trials met criteria. Most focused on quality improvement (24, 41%), antimicrobial therapy (9, 15%), or infection control (9, 15%) interventions. Designs included parallel-group (25, 42%), crossover (21, 36%), and stepped-wedge (13, 22%). Concealment of allocation was reported in 21 studies (36%). Thirteen studies (22%) reported at least one method of blinding. The median total sample size was 1,660 patients (interquartile range, 813-4,295); the median number of clusters was 12 (interquartile range, 5-24); and the median patients per cluster was 141 (interquartile range, 54-452). Sample size calculations were reported in 90% of trials, but only 54% met Consolidated Standards of Reporting Trials guidance for sample size reporting. Twenty-seven of the studies (46%) identified a fixed number of available clusters prior to trial commencement, and only nine (15%) prespecified both the number of clusters and patients required to detect the expected effect size. Overall, 36 trials (68%) achieved the total prespecified sample size. When analyzing data, 44 studies (75%) appropriately adjusted for clustering when analyzing the primary outcome. Only 12 (20%) reported an intracluster coefficient (median 0.047 [interquartile range, 0.01-0.13]).

CONCLUSIONS

Cluster randomized controlled trials in critical care typically involve a small and fixed number of relatively large clusters. The reporting of key methodological aspects of these trials is often inadequate.

A systematic review of reports of quality improvement for bronchopulmonary dysplasia

Bronchopulmonary dysplasia (BPD) is the most common morbidity of preterm infants, and its incidence has not responded to research and intervention efforts to the same degree as other major morbidities associated with prematurity. The complexity of neonatal respiratory care as well as persistent inter-institutional variability in BPD rates suggest that BPD may be amenable to quality improvement (QI) efforts. We present a systematic review of QI for BPD in preterm infants. We identified 22 reports from single centers and seven from collaborative efforts published over the past two decades. In almost all of the reports, respiratory QI interventions successfully reduced BPD or other key respiratory measures, particularly for infants with birth weight over 1000 g. Several themes and lessons from existing reports may help inform future efforts in both research and QI to impact the burden of BPD.

Impact of bundle implementation on the incidence of peri/intraventricular hemorrhage among preterm infants: a pre-post interventional study

BACKGROUND

Peri/intraventricular hemorrhage (PIVH) is a frequent cause of death and morbidity among preterm infants. Few studies have addressed the use of bundles for preventing PIVH.

OBJECTIVE

To evaluate the efficacy of a bundle of interventions designed to decrease the incidence of intraventricular hemorrhage at hospital discharge among preterm infants.

DESIGN AND SETTING

Pre-post interventional study with retrospective and prospective data collection performed before and after bundle implementation in the neonatal intensive care unit of a university hospital.

METHODS

Infants with gestational age < 32 weeks without malformations, who survived > 6 days were included. The bundle consisted of the following actions during the first 72 hours of life: maintenance of head in neutral position with the body in supine position, minimal handling, including delay of lumbar puncture until after 72 hours and absence of respiratory therapy maneuvers. Cranial ultrasound was performed on days 3, 7 and 28, or later if needed. The effect of the bundle was analyzed through logistic regression and results were adjusted for confounding variables.

RESULTS

167 infants met the inclusion criteria; 146 (87%) were analyzed. Bundle implementation was associated with decreased chances of PIVH at hospital discharge (odds ratio 0.29; 95% confidence interval 0.13-0.65). Cerebrospinal fluid collection within the first 72 hours increased the odds of PIVH of any grade during the hospital stay fourfold, after adjustment for all variables included in the model.

CONCLUSION

Implementation of a bundle of interventions to avoid intraventricular hemorrhage was effective for decreasing the incidence of all grades of PIVH in preterm infants.

Investigation Into the Current Situation and Analysis of the Factors Influencing Extrauterine Growth Retardation in Preterm Infants

Objective: This study aims to explore the occurrence of extrauterine growth retardation (EUGR) in preterm infants with a gestational age of <34 weeks, at discharge, and the factors influencing the occurrence of EUGR. Method: A retrospective analysis of 691 preterm infants with a gestational age of less than 34 weeks, born in our hospital over the past 3 years. At discharge, the growth indicators head circumference, weight, and length were used to divide the infants into an EUGR group (n = 255) and the non-EUGR group (n = 436). The occurrence of EUGR and its influencing factors were then analyzed. Results: Of the 691 preterm infants evaluated for inclusion in the study, 255 cases (36.9%) met the requirements of EUGR at discharge. The different growth indicators used, i.e., weight, length, and head circumference, classified the infants differently. The incidence of EUGR using these measures was 30.2% (209), 27.9% (193), and 23.2% (161), respectively. The results of a univariate analysis showed that gestational age, birth weight, intrauterine growth retardation (IUGR), maternal gestational hypertension, age at which the infant commenced feeding, duration of the application of an invasive ventilator, length of hospital stay, nosocomial infection, respiratory and gastrointestinal diseases, symptomatic patent ductus arteriosus, and the early onset of neonatal sepsis were correlated with the occurrence of EUGR. Further logistic multivariate regression analysis revealed that low gestational age, low birth weight, complicated IUGR, respiratory distress syndrome, and necrotizing enterocolitis were independent risk factors for EUGR in preterm infants with a gestational age <34 weeks. Conclusion: In preterm infants with a gestational age <34 weeks in our hospital, there is a high incidence of EUGR, which is affected by factors such as the gestational age, birth weight, IUGR, respiratory distress syndrome, necrotizing enterocolitis, and other factors.

A Quality Improvement Initiative to Increase Mother's Own Milk Use in a Chinese Neonatal Intensive Care Unit

Background: To evaluate the efficacy of a multidisciplinary quality improvement intervention to promote mother's own milk feeding and reduce necrotizing enterocolitis (NEC) in very low-birth-weight infants. Materials and Methods: We conducted a pre (January 2014 to March 2015)-post (April 2015 to June 2016), nonrandomized, interventional cohort study of infants born at <1,500 g birth weight and admitted to the Fudan University Children's Hospital level III neonatal intensive care unit in Shanghai. The intervention included establishing a breast milk promotion team and breast milk pumping room, educating staff and parents, and distributing teaching materials. The primary outcome was breast milk feeding rate. Secondary outcomes included incidences of NEC, NEC needing surgery, mortality, and time to full enteral feeds. Results: A total of 488 infants (210 baseline, 278 intervention) <1,500 g were enrolled. The intervention group had significantly increased feeding rates for any mother's milk (34.76% vs. 80.58%; p < 0.01) and high-volume mother's milk (≥50% of feeds; 22.86% vs. 61.15%; p < 0.01), and decreased incidence of NEC needing surgery (7.62% vs. 3.24%; adjusted odds ratio [OR] 0.32, 95% confidence interval [CI] 0.14-0.76). There were no significant differences in rates of mortality (0.5% vs. 1.49%; adjusted OR 2.10, 95% CI 0.22-19.6), NEC (10.00% vs. 7.55%; adjusted OR 0.59, 95% CI 0.31-1.14), and time to full enteral feeds (20.18 ± 1.67 days vs. 24.15 ± 1.65 days; adjusted OR = 1.09, 95% CI 0.99-1.21). Conclusions: Our quality improvement initiative increased the consumption of mother's own milk and reduced the severity of NEC in very low-birth-weight infants.

Outcomes and care practices for preterm infants born at less than 33 weeks' gestation: a quality-improvement study

BACKGROUND

Preterm birth is the leading cause of morbidity and mortality in children younger than 5 years. We report the changes in neonatal outcomes and care practices among very preterm infants in Canada over 14 years within a national, collaborative, continuous quality-improvement program.

METHODS

We retrospectively studied infants born at 23-32 weeks' gestation who were admitted to tertiary neonatal intensive care units that participated in the Evidence-based Practice for Improving Quality program in the Canadian Neonatal Network from 2004 to 2017. The primary outcome was survival without major morbidity during the initial hospital admission. We quantified changes using process-control charts in 6-month intervals to identify special-cause variations, adjusted regression models for yearly changes, and interrupted time series analyses.

RESULTS

The final study population included 50 831 infants. As a result of practice changes, survival without major morbidity increased significantly (56.6% [669/1183] to 70.9% [1424/2009]; adjusted odds ratio [OR] 1.08, 95% confidence interval [CI] 1.06-1.10, per year) across all gestational ages. Survival of infants born at 23-25 weeks' gestation increased (70.8% [97/137] to 74.5% [219/294]; adjusted OR 1.03, 95% CI 1.02-1.05, per year). Changes in care practices included increased use of antenatal steroids (83.6% [904/1081] to 88.1% [1747/1983]), increased rates of normothermia at admission (44.8% [520/1160] to 67.5% [1316/1951]) and reduced use of pulmonary surfactant (52.8% [625/1183] to 42.7% [857/2009]).

INTERPRETATION

Network-wide quality-improvement activities that include better implementation of optimal care practices can yield sustained improvement in survival without morbidity in very preterm infants.

Neonatal follow-up programs in Canada: A national survey

Background

A 2006 Canadian survey showed a large variability in neonatal follow-up practices. In 2010, all 26 tertiary level Neonatal Follow-Up clinics joined the Canadian Neonatal Follow-Up Network (CNFUN) and agreed to implement a standardized assessment (including the Bayley Scales of Infant and Toddler Development-III (Bayley-III) at 18 months corrected age for children born < 29 weeks' gestation. It is unknown whether the variability in follow-up practices lessened as a result.

Objectives

To describe the current status of neonatal follow-up services in Canada and changes over time.

Methods

A comprehensive online survey was sent to all tertiary level CNFUN Follow-up programs. Questions were based on previous survey results, current literature, and investigator expertise and consensus.

Results

Respondents included 23 of 26 (88%) CNFUN programs. All sites provide neurodevelopmental screening and referrals in a multidisciplinary setting with variations in staffing. CNFUN programs vary with most offering five to seven visits. Since 2006, assessments at 18 months CA increased from 84% to 91% of sites, Bayley-III use increased from 21% to 74% (P=0.001) and eligibility for follow-up was expanded for children with stroke, congenital diaphragmatic hernia and select anomalies detected in utero. Audit data is collected by > 80% of tertiary programs.

Conclusion

Care became more consistent after CNFUN; 18-month assessments and Bayley-III use increased significantly. However, marked variability in follow-up practices persists.

Racial and Ethnic Differences Over Time in Outcomes of Infants Born Less Than 30 Weeks' Gestation

OBJECTIVES

To examine changes in care practices over time by race and ethnicity and whether the decrease in hospital mortality and severe morbidities has benefited infants of minority over infants of white mothers.

METHODS

Infants 22 to 29 weeks' gestation born between January 2006 and December 2017 at a Vermont Oxford Network center in the United States were studied. We examined mortality and morbidity rate differences and 95% confidence intervals for African American and Hispanic versus white infants by birth year. We tested temporal differences in mortality and morbidity rates between white and African American or Hispanic infants using a likelihood ratio test on nested binomial regression models.

RESULTS

Disparities for certain care practices such as antenatal corticosteroids and for some in-hospital outcomes have narrowed over time for minority infants. Compared with white infants, African American infants had a faster decline for mortality, hypothermia, necrotizing enterocolitis, and late-onset sepsis, whereas Hispanic infants had a faster decline for mortality, respiratory distress syndrome, and pneumothorax. Other morbidities showed a constant rate difference between African American and Hispanic versus white infants over time. Despite the improvements, outcomes including hypothermia, mortality, necrotizing enterocolitis, late-onset sepsis, and severe intraventricular hemorrhage remained elevated by the end of the study period, especially among African American infants.

CONCLUSIONS

Racial and ethnic disparities in vital care practices and certain outcomes have decreased. That the quality deficit among minority infants occurred for several care practice measures and potentially modifiable outcomes suggests a critical role for quality improvement initiatives tailored for minority-serving hospitals.

Introducing evidence-based practice improvement in Chinese neonatal intensive care units

China has the largest population in the world. With rapid economic growth, the incidence of premature birth has shown an increasing trend and more neonatal intensive care units (NICUs) are being established across the country. However, there is substantial variability in clinical practice and variations in short- and long-term outcomes among patients in different NICUs. There remains a big gap between China and developed countries in terms of infant outcomes. The Evidence-based Practice for Improving Quality (EPIQ) is a successful model that has been implemented in NICUs across Canada to improve infant outcomes. We applied EPIQ in a single NICU in china and successfully reduced the incidence of ventilator-associated pneumonia, central line (CL) associated bloodstream infection (CLABSIs), and improved the breastmilk use in NICU. In the next phase, we are extending EPIQ to another 24 centers in China and have established the Chinese Neonatal Network for national collaboration, to improve infant outcomes across China.

Practice variations and rates of late onset sepsis and necrotizing enterocolitis in very preterm born infants, a review

The burden of late onset sepsis (LOS) and necrotizing enterocolitis (NEC) remains high for newborns in low- and high-income countries. Very preterm born infants born below 32 weeks gestation are at highest risk because their immune system is not yet adapted to ex-utero life, providing intensive care frequently compromises their skin or mucosa and they require a long duration of hospital stay. An epidemiological overview is difficult to provide because there is no mutually accepted definition available for either LOS or NEC. LOS incidence proportions are generally reported based on identified blood culture pathogens. However, discordance in minimum day of onset and whether coagulase negative staphylococci or fungi should be included into the reported proportions lead to variation in reported incidences. Complicating the comparison are the absence of biomarkers, ancillary lab tests or prediction models with sufficiently high positive and/or negative predictive values. The only high negative predictive values result from negative blood culture results with negative lab results allowing to discontinue antibiotic treatment. Similar difficulties exist in reporting and diagnosing NEC. Although most publications base their proportions on a modified version of Bell's stage 2 or 3, comparisons are made difficult by the multifactorial nature of the disease reflecting several pathways to intestinal necrosis, the absence of a reliable biomarker and the unclear differentiation from spontaneous intestinal perforations. Comparable reports in very low birthweight infants range between 5% and 30% for LOS and 1.6% to 7.1% for NEC. Evidence based guidelines to support treatment are missing. Treatment for LOS remains largely empirical and focused mainly on antibiotics. In the absence of a clear diagnosis, even unspecific early warning signals need to be met with antibiotic treatment. Cessation after negative blood culture is difficult unless the child was asymptomatic from the beginning. As a result, antibiotics are the most commonly prescribed medications, but unnecessary exposure may result in increased risk for mortality, NEC, further infections and childhood obesity or asthma. Finding ways to limit antibiotic use are thus important and have shown a large potential for improvement of care and limitation of cost. Over recent decades, none of the attempts to establish novel therapies have succeeded. LOS and NEC proportions remained mostly stable. During the past 10 years however, publications emerged reporting a reduction, sometimes by almost 50%. Most concern units participating in a surveillance system using quality improvement strategies to prevent LOS or NEC (e.g., hand hygiene, evidence based "bundles", feeding onset, providing own mother's milk). We conclude that these approaches display a potential for wider spread reduction of LOS and NEC and for a subsequently more successful development of novel therapies as these often address the same pathways as the prevention strategies.

The International Network for Evaluating Outcomes (iNeo) of neonates: evolution, progress and opportunities

Neonates born very preterm (before 32 weeks' gestational age), are a significant public health concern because of their high-risk of mortality and life-long disability. In addition, caring for very preterm neonates can be expensive, both during their initial hospitalization and their long-term cost of permanent impairments. To address these issues, national and regional neonatal networks around the world collect and analyse data from their constituents to identify trends in outcomes, and conduct benchmarking, audit and research. Improving neonatal outcomes and reducing health care costs is a global problem that can be addressed using collaborative approaches to assess practice variation between countries, conduct research and implement evidence-based practices. The International Network for Evaluating Outcomes (iNeo) of neonates was established in 2013 with the goal of improving outcomes for very preterm neonates through international collaboration and comparisons. To date, 10 national or regional population-based neonatal networks/datasets participate in iNeo collaboration. The initiative now includes data on >200,000 very preterm neonates and has conducted important epidemiological studies evaluating outcomes, variations and trends. The collaboration has also surveyed >320 neonatal units worldwide to learn about variations in practices, healthcare service delivery, and physical, environmental and manpower related factors and support services for parents. The iNeo collaboration serves as a strong international platform for Neonatal-Perinatal health services research that facilitates international data sharing, capacity building, and global efforts to improve very preterm neonate care.

Modifiable Risk Factors in Necrotizing Enterocolitis

Multicenter groups have reported reductions in the incidence of necrotizing enterocolitis (NEC) among preterm infants over the past 2 decades. These large-scale prevalence studies have coincided with reports from multicenter consortia and single centers of modifications in practice using quality-improvement techniques aimed at either reducing NEC risk specifically or reducing risk of mortality and multiple morbidities associated with extreme prematurity. The modifications in practice have been based on mechanistic studies, epidemiologic association data, and clinical trials. Recent reports from centers modifying practice to reduce NEC are reviewed and select modified/modifiable practices discussed.

Evidence-Based Practice: Improving the Quality of Perinatal Care

BACKGROUND

For clinical research findings to improve the quality of care and outcomes for newborn infants and their families, they need to be implemented in policy and adopted in practice.

METHODS

We describe the principles of effective dissemination and implementation of research findings and highlight examples of collaborative quality improvement strategies to ensure that guidelines, protocols, policies and practices reflect research-informed evidence.

RESULTS

Passive dissemination of research findings is generally ineffective in driving change. Implementation strategies that use multi-faceted approaches acting on different barriers to change are better at driving improvements in the quality of care practices. These initiatives are increasingly embedded within regional, national and international networks of neonatal care centres that collaborate in conducting research, implementing its findings and auditing its uptake. Examples of successful network-based collaborative quality improvement programmes include efforts to increase use of evidence-based strategies to prevent hospital-acquired bloodstream infections, optimise surfactant replacement for preterm infants, reduce the incidence of bronchopulmonary dysplasia, improve antibiotic stewardship and promote the use of human milk to prevent necrotising enterocolitis in very-low-birth-weight infants.

CONCLUSIONS

Effective dissemination and implementation are essential for research evidence to improve quality of care and outcomes for newborn infants and their families. Multifaceted initiatives within network-based collaborative quality improvement programmes facilitate continuous audit and benchmarking cycles to ensure equity of access to evidence-based care practices.

Trends in late-onset sepsis in a neonatal intensive care unit following implementation of infection control bundle: A 15-year audit

AIM

Late-onset sepsis (LOS) is a frequent and important cause of morbidity and mortality in newborn infants admitted to neonatal intensive care units (NICUs). The objective of this study is to evaluate the impact of various infection control quality measures introduced as a bundle on the trends of the LOS in a NICU.

METHODS

This was a prospective quality improvement study involving all neonates admitted to a NICU over a 15-year period between 2002 and 2016. The main focus areas of the bundle included collaborative team effort, hand hygiene, education, central line insertion and maintenance bundles and parenteral nutrition. The main outcome measures were LOS and central line-associated bloodstream infections.

RESULTS

Yearly admissions increased during study period, from 776 in 2002 to 952 in 2016. There was a progressive decrease in LOS rate, from 4.3 to 1.6 per 1000 patient days (B coefficient -0.17, 95% confidence interval -0.25, -0.09; P < 0.001), and the central line-associated bloodstream infection rate dropped from 25 in 2003 to 5 in 2016 per 1000 central line days (B coefficient -1.20, 95% confidence interval -1.84, -0.56; P = 0.001). Hand hygiene compliance rates remained consistent, over 80%. During the study period, coagulase-negative staphylococcus caused 56% and Gram-negative organisms 18% of the total infections.

CONCLUSION

Multifaceted infection control bundle practices with a concerted team effort in the implementation, with continuing education, feedback and reinforcement of best infection control practices, can sustain the gains achieved by infection control for a long period of time.

Sustained quality improvement in outcomes of preterm neonates with a gestational age less than 29 weeks: results from the Evidence-based Practice for Improving Quality Phase 3 1

Quality improvement initiatives in neonatology have yielded positive results; however, few programs have demonstrated sustainability. We evaluated an ongoing, national quality improvement initiative (Evidence-based Practice for Improving Quality Phase 3 (EPIQ-3)) on outcomes of preterm neonates with a gestational age (GA) of 22⁰-28⁶ weeks (i.e., from 22 weeks and 0 days of gestation to 28 weeks and 6 days of gestation). Data from 7459 neonates admitted to 25 Canadian centers between 2013 and 2017 were studied. Trends in mortality and major morbidities were evaluated. The number of neonates with a GA of 22⁰-23⁶ weeks increased from 90 in 2013 to 139 in 2017 without a significant change in any other GA categories. In the entire cohort, the odds of composite outcome of mortality or any major morbidity (adjusted odds ratio (AOR) 0.72, 95% confidence interval (CI) 0.61-0.84) and of necrotizing enterocolitis (AOR 0.66, 95% CI 0.49-0.89) were lower in 2017 than in 2013. When calculated per year, the odds of composite outcome (AOR 0.93, 95% CI 0.89-0.97) and odds of necrotizing enterocolitis (AOR 0.89, 95% CI 0.82-0.96) decreased significantly. Among the subgroup of neonates with a GA of 26⁰-28⁶ weeks, the odds of composite outcome (AOR 0.63, 95% CI 0.51-0.79), necrotizing enterocolitis (AOR 0.44, 95% CI 0.26-0.73), and nosocomial infection (AOR 0.64, 95% CI 0.49-0.84) were reduced. The collaborative, multidisciplinary, nationwide EPIQ-3 program improved outcomes of preterm neonates, and the improvement was sustainable over 5 years.

The MONARCH intervention to enhance the quality of antenatal and postnatal primary health services in rural South Africa: protocol for a stepped-wedge cluster-randomised controlled trial

BACKGROUND

Gaps in maternal and child health services can slow progress towards achieving the Sustainable Development Goals. The Management and Optimization of Nutrition, Antenatal, Reproductive, Child Health & HIV Care (MONARCH) study will evaluate a Continuous Quality Improvement (CQI) intervention targeted at improving antenatal and postnatal health service outcomes in rural South Africa where HIV prevalence among pregnant women is extremely high. Specifically, it will establish the effectiveness of CQI on viral load (VL) testing in pregnant women who are HIV-positive and repeat HIV testing in pregnant women who are HIV-negative.

METHODS

This is a stepped-wedge cluster-randomised controlled trial (RCT) of 7 nurse-led primary healthcare clinics to establish the effect of CQI on selected routine antenatal and postnatal services. Each clinic was a cluster, with the exception of the two smallest clinics, which jointly formed one cluster. The intervention was applied at the cluster level, where staff received training on CQI methodology and additional mentoring as required. In the control exposure state, the clusters received the South African Department of Health standard of care. After a baseline data collection period of 2 months, the first cluster crossed over from control to intervention exposure state; subsequently, one additional cluster crossed over every 2 months. The six clusters were divided into 3 groups by patient volume (low, medium and high). We randomised the six clusters to the sequences of crossing over, such that both the first three and the last three sequences included one cluster with low, one with medium, and one with high patient volume. The primary outcome measures were (i) viral load testing among pregnant women who were HIV-positive, and (ii) repeat HIV testing among pregnant women who were HIV-negative. Consenting women ≥18 years attending antenatal and postnatal care during the data collection period completed outcome measures at delivery, and postpartum at three to 6 days, and 6 weeks. Data collection started on 15 July 2015. The total study duration, including pre- and post-exposure phases, was 19 months. Data will be analyzed by intention-to-treat based on first booked clinic of study participants.

DISCUSSION

The results of the MONARCH trial will establish the effectiveness of CQI in improving antenatal and postnatal clinic processes in primary care in sub-Saharan Africa. More generally, the results will contribute to our knowledge on quality improvement interventions in resource-poor settings.

[Application of the Evidence-based Practice for Improving Quality method in neonatal intensive care units]

The Evidence-based Practice for Improving Quality (EPIQ) method was proposed by Canadian Neonatal Network for high quality health care. The method is characterized by evidence-based, targeted, collaborative and continuous concept. At present it is applied in neonatal intensive care units (NICUs). This review article focuses on the application of the method in NICUs.

Implementation strategies for guidelines at ICUs: a systematic review

Purpose The purpose of this paper is to critically analyze empirical studies related to the implementation strategies for clinical practice guidelines (CPGs) in intensive care units (ICUs). Design/methodology/approach A systematic review with a narrative synthesis adapted from Popay et al.'s method for a narrative synthesis was conducted. A search using CINAHL, Google Scholar, Academic search complete, Cochrane Register for Randomized Controlled Trials, MEDLINE via PUBMED and grey literature was conducted in 2014 and updated in 2016 (August). After reading the abstracts, titles and full-text articles, 11 ( n=11) research studies met the inclusion criteria. Findings After critical appraisal, using the Joanna Briggs Critical Appraisal Tools, eight randomized controlled trials conducted in adult and neonatal ICUs using implementation strategies remained. Popay et al.'s method for narrative synthesis was adapted and used to analyze and synthesize the data and formulate concluding statements. Included studies found that multi-faceted strategies appear to be more effective than single strategies. Strategies mostly used were printed educational materials, information/ sessions, audit, feedback, use of champion leaders, educational outreach visits, and computer or internet usage. Practical training, monitoring visits and grand rounds were less used. Practical implications Findings can be used by clinicians to implement the best combination of multi-faceted implementation strategies in the ICUs in order to enhance the optimal use of CPGs. Originality/value No systematic review was previously done on the implementation strategies that should be used best for optimal CPG implementation in the ICU.

The Canadian Preterm Birth Network: a study protocol for improving outcomes for preterm infants and their families

BACKGROUND

Preterm birth (birth before 37 wk of gestation) occurs in about 8% of pregnancies in Canada and is associated with high mortality and morbidity rates that substantially affect infants, their families and the health care system. Our overall goal is to create a transdisciplinary platform, the Canadian Preterm Birth Network (CPTBN), where investigators, stakeholders and families will work together to improve childhood outcomes of preterm neonates.

METHODS

Our national cohort will include 24 maternal-fetal/obstetrical units, 31 neonatal intensive care units and 26 neonatal follow-up programs across Canada with planned linkages to provincial health information systems. Three broad clusters of projects will be undertaken. Cluster 1 will focus on quality-improvement efforts that use the Evidence-based Practice for Improving Quality method to evaluate information from the CPTBN database and review the current literature, then identify potentially better health care practices and implement identified strategies. Cluster 2 will assess the impact of current practices and practice changes in maternal, perinatal and neonatal care on maternal, neonatal and neurodevelopmental outcomes. Cluster 3 will evaluate the effect of preterm birth on babies, their families and the health care system by integrating CPTBN data, parent feedback, and national and provincial database information in order to identify areas where more parental support is needed, and also generate robust estimates of resource use, cost and cost-effectiveness around preterm neonatal care.

INTERPRETATION

These collaborative efforts will create a flexible, transdisciplinary, evaluable and informative research and quality-improvement platform that supports programs, projects and partnerships focused on improving outcomes of preterm neonates.

Are quality improvement collaboratives effective? A systematic review

Background

Quality improvement collaboratives (QIC) have proliferated internationally, but there is little empirical evidence for their effectiveness.

Method

We searched Medline, Embase, CINAHL, PsycINFO and the Cochrane Library databases from January 1995 to December 2014. Studies were included if they met the criteria for a QIC intervention and the Cochrane Effective Practice and Organisation of Care (EPOC) minimum study design characteristics for inclusion in a review. We assessed study bias using the EPOC checklist and the quality of the reported intervention using a subset of SQUIRE 1.0 standards.

Results

Of the 220 studies meeting QIC criteria, 64 met EPOC study design standards for inclusion. There were 10 cluster randomised controlled trials, 24 controlled before-after studies and 30 interrupted time series studies. QICs encompassed a broad range of clinical settings, topics and populations ranging from neonates to the elderly. Few reports fully described QIC implementation and methods, intensity of activities, degree of site engagement and important contextual factors. By care setting, an improvement was reported for one or more of the study’s primary effect measures in 83% of the studies (32/39 (82%) hospital based, 17/20 (85%) ambulatory care, 3/4 nursing home and a sole ambulance QIC). Eight studies described persistence of the intervention effect 6 months to 2 years after the end of the collaborative. Collaboratives reporting success generally addressed relatively straightforward aspects of care, had a strong evidence base and noted a clear evidence-practice gap in an accepted clinical pathway or guideline.

Conclusions

QICs have been adopted widely as an approach to shared learning and improvement in healthcare. Overall, the QICs included in this review reported significant improvements in targeted clinical processes and patient outcomes. These reports are encouraging, but most be interpreted cautiously since fewer than a third met established quality and reporting criteria, and publication bias is likely.

Pathophysiology, screening and treatment of ROP: A multi-disciplinary perspective

The population of infants at risk for retinopathy of prematurity (ROP) varies by world region; in countries with well developed neonatal intensive care services, the highest risk infants are those born at less than 28 weeks gestational age (GA) and less than 1 kg at birth, while, in regions where many aspects of neonatal intensive and ophthalmological care are not routinely available, more mature infants up to 2000 g at birth and 37 weeks GA are also at risk for severe ROP. Treatment options for both groups of patients include standard retinal laser photocoagulation or, more recently, intravitreal anti-VEGF drugs. In addition to detection and treatment of ROP, this review highlights new opportunities created by telemedicine, where screening and diagnosis of ROP in remote locations can be undertaken by non-ophthalmologists using digital fundus cameras. The ophthalmological care of the ROP infant is undertaken in the wider context of neonatal care and general wellbeing of the infant. Because of this context, this review takes a multi-disciplinary perspective with contributions from retinal vascular biologists, pediatric ophthalmologists, an epidemiologist and a neonatologist. This review highlights the latest insights regarding cellular and molecular mechanisms in the formation of the retinal vasculature in the human infant, pathogenesis of ROP, detection and treatment of severe ROP, the risks and benefits of anti-VEGF therapy, the identification of new therapies over the horizon, and the optimal neonatal care regimen for best ROP outcomes, and the benefits and pitfalls of telemedicine in the remote screening and diagnosis of ROP, all of which have the potential to improve ROP outcomes.

Surfactant utilization and short-term outcomes in an era of non-invasive respiratory support in Canadian neonatal intensive care units

OBJECTIVE

Increased use of non-invasive respiratory support (NRS) in the delivery room management of preterm neonates has resulted in delayed surfactant treatment, yet the short-term effects of this change are unknown. The aim of this study was to comparatively evaluate the use of surfactant and the short-term outcomes prior to and after the implementation of early routine use of NRS.

STUDY DESIGN

Eligible infants of <29 weeks gestational age (GA) admitted to a Canadian tertiary neonatal center during two time periods (2005 to 2008 and 2010 to 2013) were included in this retrospective cohort study. Timing of surfactant (prophylactic vs therapeutic) and short-term outcomes were compared between the two groups. Univariate and multivariate regression analysis was performed to determine the adjusted odds ratio (AOR) along with 95% confidence interval (CI) of receiving exogenous surfactant and developing bronchopulmonary dysplasia (BPD) using the later cohort as the reference group. Subgroup analyses were also performed for infants <26 and 26 to 28^6/7 weeks GA, respectively.

RESULTS

A total of 3980 and 5137 infants were included in the first and second time periods, respectively. There was no significant difference in overall surfactant utilization between the two time periods (AOR 1.00, 95% CI 0.89, 1.13). However, between 2005 and 2008, a lower proportion of neonates received therapeutic surfactant compared with the later cohort (47.1% vs 56.9%, P<0.01) but were more likely to receive prophylactic surfactant (52.9% vs 43.1%, P<0.01). BPD overall was significantly higher in the earlier cohort (AOR 1.19, 95% CI 1.07, 1.33), particularly among the <26 weeks gestation subgroup (AOR 1.34, 95% CI 1.08, 1.66).

CONCLUSION

Early routine use of NRS did not impact overall surfactant utilization rate, although therapeutic surfactant administration rates were higher with a concomitant decrease in BPD rates.

Implementation of effective practices in health facilities: a systematic review of cluster randomised trials

Background

The capacity for health systems to support the translation of research in to clinical practice may be limited. The cluster randomised controlled trial (cluster RCT) design is often employed in evaluating the effectiveness of implementation of evidence-based practices. We aimed to systematically review available evidence to identify and evaluate the components in the implementation process at the facility level using cluster RCT designs.

Methods

All cluster RCTs where the healthcare facility was the unit of randomisation, published or written from 1990 to 2014, were assessed. Included studies were analysed for the components of implementation interventions employed in each. Through iterative mapping and analysis, we synthesised a master list of components used and summarised the effects of different combinations of interventions on practices.

Results

Forty-six studies met the inclusion criteria and covered the specialty groups of obstetrics and gynaecology (n=9), paediatrics and neonatology (n=4), intensive care (n=4), internal medicine (n=20), and anaesthetics and surgery (n=3). Six studies included interventions that were delivered across specialties. Nine components of multifaceted implementation interventions were identified: leadership, barrier identification, tailoring to the context, patient involvement, communication, education, supportive supervision, provision of resources, and audit and feedback. The four main components that were most commonly used were education (n=42, 91%), audit and feedback (n=26, 57%), provision of resources (n=23, 50%) and leadership (n=21, 46%).

Conclusions

Future implementation research should focus on better reporting of multifaceted approaches, incorporating sets of components that facilitate the translation of research into practice, and should employ rigorous monitoring and evaluation.

Determinants of developmental outcomes in a very preterm Canadian cohort

OBJECTIVES

Identify determinants of neurodevelopmental outcome in preterm children.

METHODS

Prospective national cohort study of children born between 2009 and 2011 at <29 weeks gestational age, admitted to one of 28 Canadian neonatal intensive care units and assessed at a Canadian Neonatal Follow-up Network site at 21 months corrected age for cerebral palsy (CP), visual, hearing and developmental status using the Bayley Scales of Infant and Toddler Development-Third Edition (Bayley-III). Stepwise regression analyses evaluated the effect of (1) prenatal and neonatal characteristics, (2) admission severity of illness, (3) major neonatal morbidities, (4) neonatal neuroimaging abnormalities, and (5) site on neurodevelopmental impairment (NDI) (Bayley-III score < 85, any CP, visual or hearing impairment), significant neurodevelopmental impairment (sNDI) (Bayley-III < 70, severe CP, blind or hearing aided and sNDI or death.

RESULTS

Of the 3700 admissions without severe congenital anomalies, 84% survived to discharge and of the 2340 admissions, 46% (IQR site variation 38%-51%) had a NDI, 17% (11%-23%) had a sNDI, 6.4% (3.1%-8.6%) had CP, 2.6% (2.5%-13.3%) had hearing aids or cochlear implants and 1.6% (0%-3.1%) had a bilateral visual impairment. Bayley-III composite scores of <70 for cognitive, language and motor domains were 3.3%, 10.9% and 6.7%, respectively. Gestational age, sex, outborn, illness severity, bronchopulmonary dysplasia, necrotising enterocolitis, late-onset sepsis, retinopathy of prematurity, abnormal neuroimaging and site were significantly associated with NDI or sNDI. Site variation ORs for NDI, sNDI and sNDI/death ranged from 0.3-4.3, 0.04-3.5 and 0.12-1.96, respectively.

CONCLUSION

Most preterm survivors are free of sNDI. The risk factors, including site, associated with neurodevelopmental status suggest opportunities for improving outcomes.

Roadmap to a successful quality improvement project

Although the benefits of quality improvement initiatives are largely understood by practicing neonatologists and perinatologists, the vast majority have not received any formal training in quality improvement methodology. Even as reporting requirements of quality metrics has increased from a number of outside agencies and public reporting entities, education for physicians regarding how to carry out quality improvement projects has largely remained the individual's responsibility. The first in a series of quality improvement education papers, we focus on the reasons why quality improvement matters and how to develop a team of stakeholders that will be functional and productive in addressing specific quality and safety concerns.

The role of organizational context in moderating the effect of research use on pain outcomes in hospitalized children: a cross sectional study

Background

Despite substantial research on pediatric pain assessment and management, health care professionals do not adequately incorporate this knowledge into clinical practice. Organizational context (work environment) is a significant factor in influencing outcomes; however, the nature of the mechanisms are relatively unknown. The objective of this study was to assess how organizational context moderates the effect of research use and pain outcomes in hospitalized children.

Methods

A cross-sectional survey was undertaken with 779 nurses in 32 patient care units in 8 Canadian pediatric hospitals, following implementation of a multifaceted knowledge translation intervention, Evidence-based Practice for Improving Quality (EPIQ). The influence of organizational context was assessed in relation to pain process (assessment and management) and clinical (pain intensity) outcomes. Organizational context was measured using the Alberta Context Tool that includes: leadership, culture, evaluation, social capital, informal interactions, formal interactions, structural and electronic resources, and organizational slack (staff, space, and time). Marginal modeling estimated the effects of instrumental research use (direct use of research knowledge) and conceptual research use (indirect use of research knowledge) on pain outcomes while examining the effects of context.

Results

Six of the 10 organizational context factors (culture, social capital, informal interactions, resources, and organizational slack [space and time]) significantly moderated the effect of instrumental research use on pain assessment; four factors (culture, social capital, resources and organizational slack time) moderated the effect of conceptual research use and pain assessment. Only two factors (evaluation and formal interactions) moderated the effect of instrumental research use on pain management. All organizational factors except slack space significantly moderated the effect of instrumental research use on pain intensity; informal interactions and organizational slack space moderated the effect of conceptual research use and pain intensity.

Conclusions

Many aspects of organizational context consistently moderated the effects of instrumental research use on pain assessment and pain intensity, while only a few influenced conceptual use of research on pain outcomes. Organizational context factors did not generally influence the effect of research use on pain management. Further research is required to further explore the relationships between organizational context and pain management outcomes.

Decreasing infection in neonatal intensive care units through quality improvement

OBJECTIVE

To decrease the incidence of bloodstream infection (BSI) for neonates <29 weeks gestation through quality improvement.

DESIGN

Commencing in September 2011, eight neonatal intensive care units (NICUs) in New South Wales and Australian Capital Territory, Australia participated in the Sepsis Prevention in NICUs Group project, a multicentre quality improvement initiative to reduce neonatal infection through implementation of potentially better practices and development of teaching resources. Data were collected for neonates <29 weeks gestation from D3 to 35, using point of care data entry, for BSI, central line-associated BSI (CLABSI) and antibiotic use. Exponentially weighted moving average data trend lines for rates of BSI, CLABSI and antibiotic use for each NICU were automatically generated and composite charts were provided each month to participating NICUs.

RESULTS

Between January 2012 and December 2014, data were collected from D3 to 35 for 1075 neonates <29 weeks gestation who survived >48 h, for a total of 33 933 bed days and 14 447 central line days. There was a significant decrease from 2012 to 2014 in BSI/1000 bed days (7.8±3.0 vs 3.8±1.1, p=0.000), CLABSI/1000 bed days (4.6±2.1 vs 2.1±0.8, p=0.003), CLABSI/1000 central line days (9.9±4.3 vs 5.4±1.7, p=0.012) and antibiotic days/100 bed days (31.1±4.3 vs 25.5±4.2, p=0.046).

CONCLUSIONS

This study demonstrates a >50% reduction in BSI in extremely premature neonates from D3 to 35 following a collaborative quality improvement project to reduce neonatal infection across an NICU network, supported by timely provision of data.

Pain Assessment and Management After a Knowledge Translation Booster Intervention

BACKGROUND AND OBJECTIVES

Inadequate pain treatment leaves hospitalized children vulnerable to immediate and long-term sequelae. A multidimensional knowledge translation intervention (ie, the Evidence-based Practice for Improving Quality [EPIQ]) improved pain assessment, management, and intensity outcomes in 16 units at 8 Canadian pediatric hospitals. The sustained effectiveness of EPIQ over time is unknown, however. The goals of this study were to determine the following: (1) sustainability of the impact of EPIQ on pain assessment, management, and intensity outcomes 12, 24, and 36 months after EPIQ; (2) effectiveness of a pain practice change booster (Booster) intervention to sustain EPIQ outcomes over time; and (3) influence of context on sustainability.

METHODS

A prospective, repeated measures, cluster randomized controlled trial was undertaken in the 16 EPIQ units, 12 months after EPIQ completion, to determine the effectiveness of a practice change booster (Booster) to sustain EPIQ outcomes. Generalized estimating equation models examined outcomes controlling for child and unit contextual factors.

RESULTS

Outcomes achieved during EPIQ were sustained in the use of any pain assessment measure (P = .01) and a validated pain assessment measure in the EPIQ units (P = .02) up to 36 months after EPIQ. Statistically significant improvements in pain management practices persisted in EPIQ units; results varied across time. There were no significant differences in outcomes after implementation of the Booster between the Booster and Nonbooster groups.

CONCLUSIONS

Improved pain assessment and management practices were sustained after EPIQ; however, the Booster did not seem to provide additional impact.

[Effect of breastfeeding quality improvement on breastfeeding rate in very low birth weight and extremely low birth weight infants]

OBJECTIVE

To study the effect of breastfeeding quality improvement on the breastfeeding rate in very low birth weight (VLBW) and extremely low birth weight (ELBW) infants in the neonatal intensive care unit (NICU).

METHODS

A retrospective analysis was performed for the clinical data of VLBW and ELBW infants who were admitted from July 2014 to July 2015 (pre-improvement group) and those who were admitted from August 2015 to June 2016 after the implementation of breastfeeding quality improvement measures (post-improvement group). The parameters including condition of breastfeeding (breastfeeding rate, breastfeeding amount, and breastfeeding time), duration of parenteral nutrition, time to enteral feeding, and incidence of feeding intolerance were compared between the two groups.

RESULTS

The implementation of breastfeeding quality improvement measures significantly increased breastfeeding rate and amount, significantly shortened time to addition of human milk fortifier, duration of parenteral nutrition, and time to enteral feeding, and significantly decreased the incidence of feeding intolerance.

CONCLUSIONS

Breastfeeding quality improvement measures can increase breastfeeding rate in the NICU and decrease gastrointestinal complications in preterm infants.

Prevention and management of bronchopulmonary dysplasia: Lessons learned from the neonatal research network

Despite remarkable improvements in survival of extremely premature infants, the burden of BPD among survivors remains a frustrating problem for parents and caregivers. Advances, such as antenatal steroids and surfactant replacement, which have dramatically improved survival, have not reduced BPD among survivors. Other advances that have significantly improved the combined outcome of death or BPD, such as vitamin A and avoidance of mechanical ventilation, have had smaller magnitude effects on the outcome of BPD alone. Postnatal steroids have a clear beneficial effect on BPD, but the optimal preparation, dose, and timing for maximizing benefit and minimizing harm have yet to be determined. This persistent burden of BPD among the most immature survivors remains a challenge for the NRN and other researchers in neonatal medicine.

Early removal versus expectant management of central venous catheters in neonates with bloodstream infection

BACKGROUND

Uncertainty exists regarding the management of newborn infants with a bloodstream infection and a central venous catheter in place. The central venous catheter may act as a nidus for infecting organisms and observational studies have suggested that early removal of the catheter is associated with a lower incidence of persistent or complicated infection. However, since central venous catheters provide secure vascular access to deliver nutrition and medications, the possible harms of early removal versus expectant management also need to be considered.

OBJECTIVES

To determine the effect of early removal versus expectant management of central venous catheters on morbidity and mortality in newborn infants with bloodstream infections.

SEARCH METHODS

We used the standard search strategy of the Cochrane Neonatal Review Group. This included searches of the Cochrane Central Register of Controlled Trials (CENTRAL 2015, Issue 11), MEDLINE (1966 to October 2015), EMBASE (1980 to October 2015), CINAHL (1982 to October 2015), conference proceedings and previous reviews.

SELECTION CRITERIA

Randomised and quasi-randomised controlled trials that compared early removal versus expectant management of central venous catheters in neonates with bloodstream infections.

DATA COLLECTION AND ANALYSIS

We used the standard methods of the Cochrane Neonatal Review Group.

MAIN RESULTS

We did not identify any eligible randomised controlled trials.

AUTHORS' CONCLUSIONS

There are no trial data to guide practice regarding early removal versus expectant management of central venous catheters in newborn infants with bloodstream infections. A simple and pragmatic randomised controlled trial is needed to resolve the uncertainty about optimal management in this common and important clinical scenario.

Evidence, Quality, and Waste: Solving the Value Equation in Neonatology

Rising health care costs challenge governments, payers, and providers in delivering health care services. Tremendous pressures result to deliver better quality care while simultaneously reducing costs. This has led to a wholesale re-examination of current practice methods, including explicit consideration of efficiency and waste. Traditionally, reductions in the costs of care have been considered as independent, and sometimes even antithetical, to the practice of high-quality, intensive medicine. However, it is evident that provision of evidence-based, locally relevant care can result in improved outcomes, lower resource utilization, and opportunities to reallocate resources. This is particularly relevant to the practice of neonatology. In the United States, 12% of the annual birth cohort is affected by preterm birth, and 3% is affected by congenital anomalies. Both of these conditions are associated with costly health care during, and often long after, the NICU admission. We will discuss how 3 drivers of clinical practice in neonatal care (evidence-based medicine, evidence-based economics, and quality improvement) can together optimize clinical and fiscal outcomes.
