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.

Does primary surgical closure of the patent ductus arteriosus in infants <1500 g or ≤32 weeks' gestation reduce the incidence of necrotizing enterocolitis?

BACKGROUND: The hemodynamic perturbation related to patent ductus arteriosus (PDA) is associated with a higher risk of necrotizing enterocolitis (NEC). OBJECTIVE: To determine whether primary surgical closure, as compared with treatment with indomethacin or exposure to prophylactic indomethacin, reduces the incidence of NEC in preterm infants <1500 g and/or ≤32 weeks' gestation with clinically and echocardiogram-identified PDA. METHODS: The literature was reviewed using the methodology for systematic reviews for the Consensus of Science adapted from the American Heart Association's International Liaison Committee on Resuscitation. RESULTS: Ten studies were reviewed. The incidence of NEC was not lower in infants who underwent primary surgery for closure of the PDA compared with infants treated with indomethacin or infants exposed to prophylactic indomethacin (level of evidence 2). CONCLUSION: Primary surgical closure of the PDA cannot be recommended as an intervention to decrease the incidence of NEC in infants <1500 g and/or ≤32 weeks' gestation.

HISTORIQUE: La perturbation hémodynamique liée à la persistance du canal artériel (PCA) s'associe à un risque plus élevé d'entérocolite nécrosante (ECN). OBJECTIF: Déterminer si la fermeture chirurgicale primaire par rapport au traitement à l'indométhacine ou à l'exposition à une prophylaxie à l'indométhacine réduit l'incidence d'ECN chez les prématurés de moins de 1 500 g ou d'un maximum de 32 semaines d'âge gestationnel ayant une PCA diagnostiquée sur le plan clinique et par échocardiogramme. MÉTHODOLOGIE: Les chercheurs ont analysé les publications au moyen de la méthodologie des analyses systématiques pour le Consensus of Science adaptées du comité de liaison internationale sur la réanimation de l'American Heart Association. RÉSULTATS: Les chercheurs ont analysé dix études. L'incidence d'ECN n'était pas plus faible chez les nourrissons qui avaient subi une chirurgie primaire pour fermer une PCA que chez les nourrissons traités à l'indométhacine ou exposés à une prophylaxie à l'indométhacine (qualité des preuves 2). CONCLUSION: La fermeture chirurgicale primaire de la PCA ne peut être recommandée pour réduire l'incidence d'ECN chez les nourrissons de moins de 1 500 g ou d'un maximum de 32 semaines d'âge gestationnel.

What information do parents want from the antenatal consultation?

OBJECTIVE: To explore whether the information content, process and social interaction of the antenatal consultation satisfies the informational needs of women admitted to hospital in preterm and threatened preterm labour. METHODS: Fifty women with pregnancies of gestational ages of between 25 and 32 weeks were admitted to a tertiary care perinatal referral centre and provided with an antenatal consultation about the medical risks and treatments relative to their potentially premature infant. Within 48 h following the consultation, patients were asked to respond to a questionnaire to assess their recall of the information provided, their information expectations and their anxiety level. RESULTS: The majority of respondents (92%) thought that the antenatal consultation increased their knowledge and understanding of what might happen if their infant was born preterm. Although the mean state anxiety score was high, 78% agreed that the consultation relieved some of their worry and anxiety about their baby. In rank order, respondents wanted information about chances of survival, likely medical problems and the risk for disability, followed by medical treatments and breastfeeding. They consistently recalled receiving information about chances of survival, likely medical problems and medical treatments. CONCLUSION: Following the antenatal consultation, respondents were generally satisfied with the information provided but remained highly anxious. Recall of the discussion about disability was inconsistent. They reported needing an opportunity to express their feelings, and to talk about their baby and their anticipated interaction with their baby. Recognizing these aspects can help to improve physician-patient communication.

Incidence and timing of presentation of necrotizing enterocolitis in preterm infants.

OBJECTIVES: To examine the variation in the incidence and to identify the timing of the presentation of necrotizing enterocolitis (NEC) in a cohort of preterm infants within the Canadian Neonatal Network (CNN). METHODS: This was a population-based cohort of 16 669 infants with gestational age (GA) <33 weeks, admitted to 25 NICUs participating in the CNN between January 1, 2003, and December 31(,) 2008. Variations in NEC incidence among the participating NICUs for the study period were examined. We categorized early-onset NEC as occurring at <14 days of age and late-onset NEC occurring at ≥14 days. Multivariate logistic regression analysis was performed to identify risk factors for early-onset NEC. RESULTS: The overall incidence of NEC was 5.1%, with significant variation in the risk adjusted incidence among the participating NICUs in the CNN. Early-onset NEC occurred at a mean of 7 days compared with 32 days for late-onset NEC. Early-onset NEC infants had lower incidence of respiratory distress syndrome, patent ductus treated with indomethacin, less use of postnatal steroids, and shorter duration of ventilation days. Multivariate logistic regression analysis identified that greater GA and vaginal delivery were associated with increased risk of early-onset NEC. CONCLUSIONS: Among infants <33 weeks' gestation, NEC appears to present at mean age of 7 days in more mature infants, whereas onset of NEC is delayed to 32 days of age in smaller, lower GA infants. Further studies are required to understand the etiology of this disease process.

Does the use of primary continuous positive airway pressure reduce the need for intubation and mechanical ventilation in infants ≤32 weeks' gestation?

BACKGROUND: Ventilator-induced lung injury is a recognized risk factor for bronchopulmonary dysplasia. OBJECTIVE: To determine whether primary continuous positive airway pressure (CPAP), defined as CPAP without previous endotracheal intubation for any indication, can reduce the need for intubation and mechanical ventilation in infants born at ≤32 weeks' gestational age. METHODS: The literature was reviewed using the methodology for systematic reviews for the Consensus on Resuscitation Science adapted from the American Heart Association's International Liaison Committee on Resuscitation. RESULTS: Fourteen studies were reviewed. Eleven studies provided varying degrees of supportive evidence (level of evidence 3 to 4) that the use of primary CPAP can reduce the need for intubation and mechanical ventilation. CONCLUSION: The use of CPAP as a primary intervention and mode of respiratory support is an option for infants ≤32 weeks' gestation, but avoidance of intubation and mechanical ventilation is more likely in mature infants >27 weeks' gestation.

Venous thromboembolism prophylaxis in patients undergoing cranial neurosurgery: a systematic review and meta-analysis.

BACKGROUND: Randomized clinical trials (RCTs) have usually supported using heparin prophylaxis against venous thromboembolism (VTE) in patients undergoing cranial neurosurgery. The tradeoff between benefit and bleeding risk, however, has not been adequately characterized. OBJECTIVE: To conduct a systematic review and meta-analysis assessing the extent to which low-dose unfractionated heparin (LDUH) or low-molecular-weight heparin (LMWH) prophylaxis reduces the rate of VTE and increases the rate of intracerebral hemorrhage (ICH) and other bleeding in patients undergoing elective cranial neurosurgery. METHODS: We selected RCTs that evaluated LDUH or LMWH prophylaxis of VTE in patients undergoing elective cranial neurosurgery. A meta-analysis assessing heparins vs no heparin (either with or without mechanical methods) was performed. RESULTS: Eight RCTs were identified. Six RCTs involving 1170 patients evaluated LDUH or LMWH vs a control group. Five of 6 trials found a significant reduction in the risk of symptomatic and asymptomatic VTE with heparin prophylaxis. The pooled risk ratio was 0.58 (95% confidence interval, 0.45-0.75). ICH was more common in those receiving heparin, but not statistically significantly. For every 1000 patients who receive heparin prophylaxis, 91 VTE events will be prevented (approximately 35 of which are proximal deep vein thrombosis or pulmonary embolism and 9 to 18 of which are symptomatic), whereas 7 ICHs and 28 more minor bleeds will occur. CONCLUSION: Heparin prophylaxis for patients undergoing elective cranial neurosurgery reduces the risk of VTE but may also increase bleeding risks with a ratio of serious or symptomatic VTE relative to serious bleeding that is only slightly favorable.

Triplet infants with birthweight < or = 1250 grams: how well do they compare with twin and singleton infants at 36 to 48 months of age?

The purpose of this study was to determine if triplet infants with birthweight < or = 1250 g were at increased risk of long-term disability compared with similar birthweight and gestational age singletons and twins. This was a retrospective cohort study of < or = 1250-g infants admitted to a regional neonatal intensive care unit from 1986 to 2001 with follow-up to 36 to 48 months corrected gestational age. Outcomes studied were cognitive ability, cerebral palsy, and neurosensory impairment at 36 to 48 months. Enrollment was 1717 infants: 59 triplets, 402 twins, and 1256 singletons. Triplet infants differed from twin or singleton infants because they were more likely to have older, married mothers (relative risk [RR] 3.62, 95% CI 1.31, 5.94), be products of assisted reproductive technology pregnancies (RR 29.59, 95% CI 13.97, 62.68), be exposed to antenatal steroids (RR 1.55, 95% CI 1.38, 1.75), and were all delivered by cesarean section. Triplet infants had lower risk of having intraventricular hemorrhage (RR 0.19, 95% CI 0.05, 0.75). The risk of cerebral palsy, cognitive delay, total major disability, or chronic lung disease was similar in triplet and twin infants compared with singleton infants. The lower risk of having intraventricular hemorrhage in triplet infants may have been due to the use of antenatal corticosteroids and cesarean section delivery.
