A systematic review of reports of quality improvement for bronchopulmonary dysplasia

Scholarly Impact of Quality Improvement Reports in Neonatology

OBJECTIVE

 Neonatology quality improvement (QI) projects can improve the safety and value of health care, but the scholarly impact of published QI projects is unclear. We measured scholarly citation and media attention garnered by published neonatology QI projects and analyzed project or publication characteristics associated with increased impact metrics.

STUDY DESIGN

 We identified publications between 2016 and 2019 using mapping review methodology. We correlated project characteristics with measures of scholarly citation in Scopus and Google Scholar, and media attention as measured by Altmetrics. We collected Citation and Altmetric data in 2023.

RESULTS

 The search identified 148 eligible articles, with a median citation count of 7 based on Scopus (or 12, based on Google Scholar) and a median Altmetric score of 2. Notably, 66% of articles published in a journal with an Impact Factor (IF) had more citations per year than would be expected from the IF value. Higher scientific citations were associated with articles reporting process and cost outcomes; implementing interventions that addressed family education or organizational change; and using regression analysis. Higher media attention was associated with multicenter projects, longer intervention periods, and projects scoring higher on the Quality Improvement Minimum Quality Criteria Set (QI-MQCS) rubric.

CONCLUSION

 Published neonatology QI projects are well cited in subsequent scientific publications, with the choice of project outcome, interventions, and analytic strategy influencing citation metrics. Adherence to QI-MQCS guidelines was favorably associated with media attention, but not with scholarly citations.

KEY POINTS

· Neonatology QI publications are frequently cited.. · Projects with cost data receive more citations.. · Citation and media mention predictors differ..

Finding treasure in the journey: a single center quality improvement bundle to reduce bronchopulmonary dysplasia

BACKGROUND

Reducing bronchopulmonary dysplasia (BPD) utilizing a single intervention has been challenging. The quality improvement (QI) bundle approach may better address BPD multifactorial risk factors.

METHODS

A single-center interdisciplinary quality improvement (QI) initiative to enhance respiratory care for preterm infants born less than 30 weeks gestation.

GLOBAL AIM

To reduce BPD in preterm infants.

SMART AIM

Introduce and implement a comprehensive, evidence-based respiratory care bundle within 12 months, targeting areas needing improvement in our practices.

RESULTS

Our preplanned improvement targets were achieved for all process measures. Overall BPD incidence did not change (45% vs. 44.3%). After the QI intervention, inborn infants had a lower BPD rate, though not statistically significant (38.7% vs. 30.3%, p = 0.22), with a significant reduction in grade 1 BPD (24.5% vs. 12.4%, p = 0.032).

CONCLUSION

Structured interdisciplinary QI work tailored to local settings can improve respiratory care and possibly amend the outcomes of infants at risk for BPD.

Inter-hospital variations in the respiratory outcomes of very and extremely pre-term infants: A cohort study in Japan

BACKGROUND

Hospital-level and international variations exist in the management strategies of bronchopulmonary dysplasia (BPD). However, studies evaluating hospital-level variations in the respiratory outcomes of pre-term infants associated with differing management strategies of BPD are lacking.

OBJECTIVE

Herein, we aimed to assess inter-hospital variations in the respiratory outcomes of BPD in very pre-term and extremely pre-term infants.

METHODS

In this cohort study, the administrative claims and discharge summary data were extracted from 276 hospitals in Japan between April 2014 and March 2016. This study assessed neonates of a gestational age of 22-31 weeks old, who had been hospitalised for ≥7 days. The primary outcome was a BPD defined using any respiratory support, such as supplemental oxygen, high-flow nasal cannula, CPAP, or mechanical ventilation at 36 weeks PMA. The median odds ratio (MOR) was calculated using a multilevel logistic regression model, including baseline characteristics, comorbidities, and treatment as covariates, to evaluate the inter-hospital variation of the outcome.

RESULTS

Of the 8143 neonates from across 132 hospitals, 53.7% were male, with a mean gestational age (standard deviation) of 28.0 (2.5)-weeks-old and birthweight of 1086 (386) g. Among these patients, BPD occurred in 2737 (33.6%). The MOR was 2.49, representing the median value of odds ratios when comparing two neonates with identical covariates from hospitals with high and low propensity for the outcomes to occur.

CONCLUSIONS

Outcome variations in the BPD were observed among hospitals in Japan, even after adjusting for individual factors, including gestational age, birthweight, comorbidities, and treatments. Thus, in Japan, developing strategies is essential to decrease the BPD rates, while minimising inter-hospital heterogeneity, to improve the healthcare quality for pre-term neonates.

Neonatal respiratory care practice among level III and IV NICUs in New England

OBJECTIVES

To assess respiratory care guidelines and explore variations in management of very low birth weight (VLBW) infants within a collaborative care framework. Additionally, to gather clinical leaders' perspectives on guidelines and preferences for ventilation modalities.

STUDY DESIGN

Leaders from each NICU participated in a practice survey regarding the prevalence of unit clinical guidelines, and management, at many stages of care.

RESULTS

Units have an average of 4.3 (±2.1) guidelines, of 9 topics queried. Guideline prevalence was not associated with practice or outcomes. An FiO2 requirement of 0.3-0.4 and a CPAP of 6-7 cmH2O, are the most common thresholds for surfactant administration, which is most often done after intubation, and followed by weaning from ventilatory support. Volume targeted ventilation is commonly used. Extubation criteria vary widely.

CONCLUSIONS

Results identify trends and areas of variation and suggest that the presence of guidelines alone is not predictive of outcome.

Quality Improvement Interventions to Prevent Intraventricular Hemorrhage: A Systematic Review

OBJECTIVES

Quality improvement may reduce the incidence and severity of intraventricular hemorrhage in preterm infants. We evaluated quality improvement interventions (QIIs) that sought to prevent or reduce the severity of intraventricular hemorrhage.

METHODS

PubMed, CINAHL, Embase, and citations of selected articles were searched. QIIs that had reducing incidence or severity of intraventricular hemorrhage in preterm infants as the primary outcome. Paired reviewers independently extracted data from selected studies.

RESULTS

Eighteen quality improvement interventions involving 5906 infants were included. Clinical interventions in antenatal care, the delivery room, and the NICU were used in the QIIs. Four of 10 QIIs reporting data on intraventricular hemorrhage (IVH) and 9 of 14 QIIs reporting data on severe IVH saw improvements. The median Quality Improvement Minimum Quality Criteria Set score was 11 of 16. Clinical intervention heterogeneity and incomplete information on quality improvement methods challenged the identification of the main reason for the observed changes. Publication bias may result in the inclusion of more favorable findings.

CONCLUSIONS

QIIs demonstrated reductions in the incidence and severity of intraventricular hemorrhage in preterm infants in some but not all settings. Which specific interventions and quality improvement methods were responsible for those reductions and why they were successful in some settings but not others are not clear. This systematic review can assist teams in identifying potentially better practices for reducing IVH, but improvements in reporting and assessing QIIs are needed if systematic reviews are to realize their potential for guiding evidence-based practice.

Measuring practice preference variation for quality improvement in neonatal respiratory care

OBJECTIVES

The authors sought to measure and compare practice preference variation in neonatal respiratory care within and between neonatal intensive care units (NICUs) using the Neonatology Survey of Interdisciplinary Groups in Healthcare Tool (NSIGHT).

STUDY DESIGN

Eleven NICUs completed the NSIGHT between 2019 and 2021. Net preference was measured by mean response; agreement was ranked by standard distribution of response values. Heat maps showed comparisons between NICUs and disciplines.

RESULTS

NICUs and individuals agreed most often on use of pressure support with mandatory ventilation and on use of non-invasive positive pressure ventilation for apnea. High preference variation surrounded decisions for invasive ventilation versus continuous positive airway pressure for extremely low birth weight infants. Preference difference was most frequent between neonatologists and nurses.

CONCLUSIONS

Patterns of practice preference variation in neonatal respiratory care are specific to clinical scenario. Measuring preference variation may inform psychology of change and strengthen quality improvement efforts.

Synergistic effects of achieving perinatal interventions on bronchopulmonary dysplasia in preterm infants

To investigate the effect of perinatal interventions on the risk of severe BPD (sBPD) and death in extremely preterm infants (EPIs) and their synergistic effects. This was a secondary analysis of the prospective cohort Chinese Neonatal Network (CHNN). Infants with a birth weight of 500 to 1250 g or 24-28 weeks completed gestational age were recruited. The impacts and the synergistic effects of six evidence-based perinatal interventions on the primary outcomes of sBPD and death were assessed by univariate and multivariable logistic regression modeling. Totally, 6568 EPIs were finally enrolled. Antenatal corticosteroid (adjusted OR, aOR, 0.74; 95%CI, 0.65-083), birth in centers with tertiary NICU (aOR, 0.64; 95%CI, 0.57-0.72), preventing intubation in the delivery room (aOR, 0.65; 95%CI, 0.58-0.73), early caffeine therapy (aOR, 0.59; 95%CI, 0.52-0.66), and early extubating (aOR, 0.42; 95%CI 0.37-0.47), were strongly associated with a lower risk of sBPD and death while early surfactant administration was associated with a lower risk of death (aOR, 0.84; 95%CI, 0.72, 0.98). Compared with achieving 0/1 perinatal interventions, achieving more than one intervention was associated with decreased rates (46.6% in 0/1 groups while 38.5%, 29.6%, 22.2%, 16.2%, and 11.7% in 2/3/4/5/6-intervention groups respectively) and reduced risks of sBPD/death with aORs of 0.76(0.60, 0.96), 0.55(0.43, 0.69), 0.38(0.30, 0.48), 0.28(0.22, 0.36), and 0.20(0.15, 0.27) in 2, 3, 4, 5, and 6 intervention groups respectively. Subgroup analyses showed consistent results.

CONCLUSION

Six perinatal interventions can effectively reduce the risk of sBPD and death in a synergistic form.

WHAT IS KNOWN

• Bronchopulmonary dysplasia (BPD) is a multifactorial chronic lung disease associated with prematurity. The effective management of BPD requires a comprehensive set of interventions. However, the extent to which these interventions can mitigate the risk of severe outcomes, such as severe BPD or mortality, or if they possess synergistic effects remains unknown.

WHAT IS NEW

• The implementation of various perinatal interventions, such as prenatal steroids, birth in centers with tertiary NICU, early non-Invasive respiratory support, surfactant administration within 2 hours after birth, early caffeine initiation within 3 days, and early extubation within 7 days after birth has shown promising results in the prevention of severe bronchopulmonary dysplasia (BPD) or mortality in extremely preterm infants. Moreover, these interventions have demonstrated synergistic effects when implemented in combination.

Quality improvement in the golden hour for premature infants: a scoping review

BACKGROUND AND OBJECTIVE

Evidence-based research has shown that golden hour quality improvement (QI) measures can improve the quality of care and reduce serious complications of premature infants. Herein, we sought to review golden hour QI studies to evaluate the impact on the outcome of preterm infants.

METHODS

A comprehensive literature search was conducted in PubMed, Embase, Cochrane Library, and SinoMed databases from inception to April 03, 2023. Only studies describing QI interventions in the golden hour of preterm infants were included. Outcomes were summarized and qualitative synthesis was performed.

RESULTS

Ten studies were eligible for inclusion. All studies were from single centers, of which nine were conducted in the USA and one in Israel. Seven were pre-post comparative studies and three were observational studies. Most included studies were of medium quality (80%). The most common primary outcome was admission temperatures and glucose. Five studies (n = 2308) reported improvements in the admission temperature and three studies (n = 2052) reported improvements in hypoglycemia after QI. Four studies (n = 907) showed that the incidence of bronchopulmonary dysplasia (BPD) was lower in preterm infants after QI: 106/408 (26.0%) vs. 122/424(29.5%) [OR = 0.68, 95% CI 0.48-0.97, p = 0.04].

CONCLUSIONS

Our study showed that the golden hour QI bundle can improve the short-term and long-term outcomes for extremely preterm infants. There was considerable heterogeneity and deficiencies in the included studies, and the variation in impact on outcomes suggests the need to use standardized and validated measures. Future studies are needed to develop locally appropriate, high-quality, and replicable QI projects.

Trends in Mortality and Morbidities for Infants Born 24 to 28 Weeks in the US: 1997-2021

BACKGROUND

Mortality and morbidity for very preterm infants in the United States decreased for years. The current study describes recent changes to assess whether the pace of improvement has changed.

METHODS

Vermont Oxford Network members contributed data on infants born at 24 to 28 weeks' gestation from 1997 to 2021. We modeled mortality, late-onset sepsis, necrotizing enterocolitis, chronic lung disease, severe intraventricular hemorrhage, severe retinopathy of prematurity, and death or morbidity by year of birth using segmented relative risk regression, reporting risk-adjusted annual percentage changes with 95% confidence intervals overall and by gestational age week.

RESULTS

Analyses of data for 447 396 infants at 888 hospitals identified 3 time point segments for mortality, late onset sepsis, chronic lung disease, severe intraventricular hemorrhage, severe retinopathy of prematurity, and death or morbidity, and 4 for necrotizing enterocolitis. Mortality decreased from 2005 to 2021, but more slowly since 2012. Late-onset sepsis decreased from 1997 to 2021, but more slowly since 2012. Severe retinopathy of prematurity decreased from 2002 to 2021, but more slowly since 2011. Necrotizing enterocolitis, severe intraventricular hemorrhage, and death or morbidity were stable since 2015. Chronic lung disease has increased since 2012. Trends by gestational age generally mirror those for the overall cohort.

CONCLUSIONS

Improvements in mortality and morbidity have slowed, stalled, or reversed in recent years. We propose a 3-part strategy to regain the pace of improvement: research; quality improvement; and follow through, practicing social as well as technical medicine to improve the health and well-being of infants and families.

Measuring practice preference variation for quality improvement: development of the Neonatology Survey of Interdisciplinary Groups in Healthcare Tool (NSIGHT)

BACKGROUND

Understanding behavioural psychology and the human side of change are guiding principles for quality improvement (QI). Tools to measure these to guide improvement efforts are lacking.

METHODS

We created a clinical vignette-based survey to measure provider preferences for respiratory care in the neonatal intensive care unit. Fourteen vignettes were included, each vignette offering two reasonable practice choices. Responses were based on a 5-point Likert scale, ranging from neutral to strong preference for either choice. The survey was completed by physicians, nurses, advanced practice providers and respiratory therapists in 2017 and again in 2019. Net preference was measured as the median value of responses, and agreement was measured as the SD of responses. Net preference and agreement were assessed for all responses, by discipline, and by year.

RESULTS

Response rates were 51% of all staff in 2017 and 57% in 2019. Vignettes asking about non-invasive respiratory support showed more defined net preferences and higher agreement between years, coinciding with QI efforts and guideline implementation in this area during the interval time. Results on other areas of practice were consistent between years. Discipline comparisons showed nurses and physicians agreed the least often. Six response patterns were identified, ranging from net preference and high agreement to no net preference and low agreement.

CONCLUSION

We propose this survey, called the Neonatology Survey of Interdisciplinary Groups in Healthcare Tool, is a novel method for measurement of hospital unit psychology and culture. Demonstrated improvement where QI efforts were focused and consistency in results in other areas support the validity of this tool. Measuring the human side of change may impact QI efforts.

Developing a Respiratory Quality Improvement Program to Prevent and Treat Bronchopulmonary Dysplasia in the Neonatal Intensive Care Unit

Improvements in respiratory care have resulted in improved outcomes for preterm infants over the past three decades. To target the multifactorial nature of neonatal lung diseases, neonatal intensive care units (NICUs) should consider developing comprehensive respiratory quality improvement programs that address all drivers of neonatal respiratory disease. This article presents a potential framework for developing a quality improvement program to prevent bronchopulmonary dysplasia in the NICU. Drawing on available research and quality improvement reports, the authors discuss key components, measures, drivers, and interventions that should be considered when building a respiratory quality improvement program devoted to preventing and treating bronchopulmonary dysplasia.

Infection prevention and control measures for preterm infants discharged into the community: a scoping review protocol

BACKGROUND

Infection prevention and control (IPC) is an evidence-based and practical approach to prevention of harm by infection (Infection prevention and control https://www.who.int/health-topics/infection-prevention-and-control#tab=tab_1 ). IPC recommendations targeted at community-acquired infection aim to prevent illness and subsequent hospital readmission. Cohesive guidance for parents of preterm infants has not been clearly established. The review objectives are to identify and map the global characteristics of IPC measures/recommendations for parents of preterm infants discharged home to the community.

METHODS

The scoping review will be conducted using the JBI methodological approach for scoping reviews and reported following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Scoping Review extension (PRISMA ScR) and the PRISMA extension for reporting literature searches in systematic reviews. Electronic databases will be searched and limited by publication year (2013-present day). Grey literature, reference lists and expert-provided sources will be searched against predetermined criteria. A minimum of two authors will independently screen evidence sources and chart evidence on a predetermined charting form. Sources including IPC measures, or recommendations for parents of preterm infants during discharge planning or in the community/home, will be permitted within inclusion criteria. Limits include human studies only and evidence from 2013-present day. Recommendations aimed at professional implementation will be excluded. A descriptive summary of findings will be presented, with diagrammatic and tabular representation.

DISCUSSION

Collated evidence will guide future research which will subsequently aim to develop policy and enhance clinical approaches.

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.

Respiratory support strategies in the prevention of bronchopulmonary dysplasia: A single center quality improvement initiative

BACKGROUND AND OBJECTIVES

Bronchopulmonary dysplasia (BPD) continues to be a significant morbidity affecting very preterm infants, despite multiple advancements in therapies to treat respiratory distress syndrome and prevent BPD. Local quality improvement (QI) efforts have shown promise in reducing unit or system-wide rates of BPD. In preterm infants born between 23- and 32-weeks' gestation, our aim was to decrease the rate of BPD at 36 weeks corrected gestational age from 43% to 28% by January 2019.

METHODS

Directed by a multidisciplinary respiratory QI team, we gradually implemented the following interventions to reach our aim: (1) early initiation of non-invasive ventilation in the delivery room, (2) initiation of caffeine prior to 24 h of life, (3) administration of early selective surfactant per a well-defined guideline, (4) continuation of non-invasive ventilation until 32 and 0/7 weeks corrected gestational age (CGA), and (5) a revision of the early selective surfactant guideline. Outcome measures included rates of BPD, and process measures included compliance with the above interventions.

RESULTS

A total of 509 infants with an average gestational age of 29 1/7 weeks and birth weight of 1,254 (SD±401) grams were included. The rate of BPD in our unit decreased from a baseline of 43% to 19% from the start of the project in October 2016 until the first quarter of 2022 (p < 0.00001). The greatest reductions in BPD rates were seen after the initiation of the guideline to extend non-invasive ventilation until 32 0/7 weeks CGA. The rate of severe BPD decreased from 22% to 9%.

CONCLUSIONS

In preterm infants born between 23- and 32-weeks' gestation, our local QI interventions to reduce rates of BPD were associated with a reduction in rates by 56%. Increased use of antenatal steroids and higher birth weights post- vs. pre-intervention may have contributed to this successes.

Impact of early respiratory care for extremely preterm infants

Despite advances in neonatal intensive care, more than half of surviving infants born extremely preterm (EP; < 28 weeks' gestation) develop bronchopulmonary dysplasia (BPD). Prevention of BPD is critical because of its associated mortality and morbidity, including adverse neurodevelopmental outcomes and respiratory health in later childhood and beyond. The respiratory care of EP infants begins before birth, then continues in the delivery room and throughout the primary hospitalization. This chapter will review the evidence for interventions after birth that might improve outcomes for infants born EP, including the timing of umbilical cord clamping, strategies to avoid or minimize exposure to mechanical ventilation, modes of mechanical ventilation and non-invasive respiratory support, oxygen saturation targets, postnatal corticosteroids and other adjunct therapies.

Clinical Characteristics and Outcomes Until 2 Years of Age in Preterm Infants With Typical Chest Imaging Findings of Bronchopulmonary Dysplasia: A Propensity Score Analysis

Objective: The goal of the current study was to assess the associations of typical chest imaging findings of bronchopulmonary dysplasia (BPD) in preterm infants with clinical characteristics and outcomes until 2 years of age. Method: This retrospective cohort study enrolled 256 preterm infants with BPD who were admitted between 2014 and 2018. A propensity score analysis was used to adjust for confounding factors. The primary outcomes were the severity of BPD, home oxygen therapy (HOT) at discharge and mortality between 28 days after birth and 2 years of age. A multivariate logistic regression analysis was performed to identify related variables of mortality. Results: Seventy-eight patients with typical chest imaging findings were enrolled, of which 50 (64.1%) were first found by CXR, while 28 (35.9%) were first found by CT. In addition, 85.9% (67/78) were discovered before 36 weeks postmenstrual age (PMA) (gestational age [GA] < 32 weeks) or before 56 days after birth (GA > 32 weeks). After propensity score matching, the matched groups consisted of 58 pairs of patients. Those with typical imaging findings had a remarkably higher mortality rate (29.3 vs. 12.1%, p = 0.022, OR 3.021), higher proportion of severe BPD (32.8 vs. 12.1%, p = 0.003, OR 4.669) and higher rate of HOT at discharge (74.1 vs. 46.6%, p = 0.002, OR 3.291) than those without typical imaging findings. The multivariate logistic regression analysis showed that typical imaging findings ≤ 7 days and typical typical imaging findings >7 days were independent risk factors for mortality in preterm infants with BPD (OR 7.794, p = 0.004; OR 4.533, p = 0.001). Conclusions: More attention should be given to chest imaging findings of BPD, especially in the early stage (within 7 days). Early recognition of the development of BPD helps early individualized treatment of BPD. Clinical Trial Registration:www.ClinicalTrials.gov, identifier: NCT04163822.
