Higher- or Usual-Volume Feedings in Infants Born Very Preterm: A Randomized Clinical Trial.

OBJECTIVE: To determine whether higher-volume feedings improve postnatal growth among infants born very preterm. STUDY DESIGN: Randomized clinical trial with 1:1 parallel allocation conducted from January 2015 to June 2018 in a single academic medical center in the US. In total, 224 infants with a birth weight 1001-2500 g born at <32 weeks of gestation were randomized to higher-volume (180-200 mL/kg/d) or usual-volume (140-160 mL/kg/d) feedings after establishing full enteral feedings (≥120 mL/kg/d). The primary outcome was growth velocity (g/kg/d) from randomization to study completion at 36 weeks of postmenstrual age or hospital discharge if earlier. RESULTS: Growth velocity increased among infants in the higher-volume group compared with the usual-volume group (mean [SD], 20.5 [4.5] vs 17.9 [4.5] g/kg/d; P < .001). At study completion, all measurements were higher among infants in the higher-volume group compared with the usual-volume group: weight (2365 [324] g, z score -0.60 [0.73] vs 2200 [308] g, z score -0.94 [0.71]; P < .001); head circumference (31.9 [1.3] cm, z score -0.30 [0.91] vs 31.4 [1.3] cm, z score -0.53 [0.84]; P = .01); length (44.9 [2.1] cm, z score -0.68 [0.88] vs 44.4 [2.0], z score -0.83 [0.84]; P = .04); and mid-arm circumference (8.8 [0.8] cm vs 8.4 [0.8] cm; P = .002). Bronchopulmonary dysplasia, patent ductus arteriosus, necrotizing enterocolitis, or other adverse outcomes did not differ between groups. CONCLUSIONS: In infants born very preterm weighing 1001-2500 g at birth, higher-volume feedings increased growth velocity, weight, head circumference, length, and mid-arm circumference compared with usual-volume feedings without adverse effects.

Quality Improvement Project to Reduce Delayed Vaccinations in Preterm Infants.

BACKGROUND: Preterm infants are especially vulnerable to infectious diseases. Although vaccinations are a safe and effective measure to protect preterm infants from vaccine-preventable diseases, delays in vaccinations are not uncommon. PURPOSE: The goal of this quality improvement project was to improve on time vaccinations of preterm infants hospitalized in the neonatal intensive care unit. METHODS: The Plan-Do-Study-Act model of quality improvement was adopted to develop, test, and implement interventions aimed at improving timely vaccination of preterm infants. The primary outcome measure of interest was the rate of on time vaccination, which was defined as the proportion of medically eligible preterm infants who received vaccinations within 2 weeks of the recommended schedule. RESULTS: Baseline on time vaccination rate was only 36%. Following several Plan-Do-Study-Act cycles, a steady increase in on time vaccinations of eligible infants was observed, and a new baseline on time vaccination rate of 82% was achieved. IMPLICATIONS FOR PRACTICE: Simple interventions implemented within the context of Plan-Do-Study-Act cycles are effective in improving timely vaccinations among preterm infants. IMPLICATIONS FOR RESEARCH: Future research that focuses on vaccinations in preterm infants is needed to further reinforce the safety and efficacy of vaccines. Effective methods on how to disseminate and apply this knowledge to practice should also be studied.Video Abstract available at http://links.lww.com/ANC/A27.

Improving Time to Goals of Care Discussions in Invasively Ventilated Preterm Infants.

BACKGROUND AND OBJECTIVES: The challenge of identifying preterm infants with bronchopulmonary dysplasia (BPD) that need tracheostomy placement may delay goals of care (GOC) discussions. By identifying infants with a low probability of ventilation liberation, timely GOC discussions may reduce the time to tracheostomy. Our SMART aim was to reduce the postmenstrual age (PMA) of GOC discussions by 20% in infants with BPD and prolonged invasive ventilatory requirement by October 2020. METHODS: Our group conducted a quality improvement initiative at the University of Alabama at Birmingham. Infants were included if born at <32 weeks' gestation and exposed to invasive ventilation for ≥2 weeks beyond 36 weeks' PMA. Interventions included (1) consensus of BPD infants at risk for tracheostomy dependence, (2) monthly multidisciplinary tracheostomy meetings, and (3) development and utilization of tracheostomy educational content for families. Statistical process control charts were used for all analyses. RESULTS: A total of 79 infants were included in analyses, of which 44 infants either received a tracheostomy or died. From X-mR control chart analysis, there was special cause variation in the time to GOC discussions, which decreased from 62 to 51 weeks' PMA related to monthly multidisciplinary conferences. The average PMA at tracheostomy decreased from 80 weeks to 63 weeks with no change in the frequency of tracheostomy placement or discordant GOC discussions in which infants survived to hospital discharge without a tracheostomy. CONCLUSIONS: In infants with ventilator-dependent BPD, standardization of GOC discussions reduced the PMA of GOC discussions and tracheostomy.

A Quality Improvement Bundle to Improve Outcomes in Extremely Preterm Infants in the First Week.

OBJECTIVES: Our objective with this quality improvement initiative was to reduce rates of severe intracranial hemorrhage (ICH) or death in the first week after birth among extremely preterm infants. METHODS: The quality improvement initiative was conducted from April 2014 to September 2020 at the University of Alabama at Birmingham's NICU. All actively treated inborn extremely preterm infants without congenital anomalies from 22 + 0/7 to 27 + 6/7 weeks' gestation with a birth weight ≥400 g were included. The primary outcome was severe ICH or death in the first 7 days after birth. Balancing measures included rates of acute kidney injury and spontaneous intestinal perforation. Outcome and process measure data were analyzed by using p-charts. RESULTS: We studied 820 infants with a mean gestational age of 25 + 3/7 weeks and median birth weight of 744 g. The rate of severe ICH or death in the first week after birth decreased from the baseline rate of 27.4% to 15.0%. The rate of severe ICH decreased from a baseline rate of 16.4% to 10.0%. Special cause variation in the rate of severe ICH or death in the first week after birth was observed corresponding with improvement in carbon dioxide and pH targeting, compliance with delayed cord clamping, and expanded use of indomethacin prophylaxis. CONCLUSIONS: Implementation of a bundle of evidence-based potentially better practices by using specific electronic order sets was associated with a lower rate of severe ICH or death in the first week among extremely preterm infants.

Oxygen saturation histogram monitoring to reduce death or retinopathy of prematurity: a quality improvement initiative.

OBJECTIVES: Maintaining preterm infants within a goal oxygen saturation range challenges care providers. Through periodic assessment of saturation trends on infants' bedside histogram reports, our initiative aimed to (1) increase time spent at goal saturations and (2) reduce death or severe retinopathy of prematurity. STUDY DESIGN: The initiative integrated histogram monitoring into provider, respiratory, and nursing care. Achieved oxygen saturations, chart audits, and bedside histogram monitoring flowsheets provided process measures with the outcome measure of death or severe retinopathy of prematurity. RESULTS: In infants <29 weeks' gestation (n = 518), the rate of death or severe retinopathy of prematurity prior to hospital discharge decreased from 32.1% to 18.0%. Time at goal saturations (90-95%) increased from 48.7% to 57.6%. CONCLUSION: In infants born at <29 weeks' gestation, periodic, multidisciplinary oxygen saturation histogram monitoring improved time at goal saturations and was associated with a reduction in death or severe retinopathy of prematurity.

Early-Onset Neonatal Sepsis with Extended Spectrum Beta-Lactamase Producing Escherichia Coli in Infants Born to South and South East Asian Immigrants: A Case Series.

Extended-spectrum ß -lactamase (ESBL)-producing Enterobacteriaceae represent a major worldwide threat. We present three cases of early onset ESBL Escherichia coli sepsis in infants born to families from South and Southeast Asia to inform the practitioner community about this emerging threat. Infants with suspected sepsis, whose mother is from Asia or Southeast Asia, should be suspected of having an infection with an ESBL-producing organism, and practitioners should strongly consider adding a carbapenem to their usual initial antibiotic regimen.

A ferret model of COPD-related chronic bronchitis.

Chronic obstructive pulmonary disease (COPD) is the third leading cause of death in the US. The majority of COPD patients have symptoms of chronic bronchitis, which lacks specific therapies. A major impediment to therapeutic development has been the absence of animal models that recapitulate key clinical and pathologic features of human disease. Ferrets are well suited for the investigation of the significance of respiratory diseases, given prior data indicating similarities to human airway physiology and submucosal gland distribution. Here, we exposed ferrets to chronic cigarette smoke and found them to approximate complex clinical features of human COPD. Unlike mice, which develop solely emphysema, smoke-exposed ferrets exhibited markedly higher numbers of early-morning spontaneous coughs and sporadic infectious exacerbations as well as a higher level of airway obstruction accompanied by goblet cell metaplasia/hyperplasia and increased mucus expression in small airways, indicative of chronic bronchitis and bronchiolitis. Overall, we demonstrate the first COPD animal model exhibiting clinical and pathologic features of chronic bronchitis to our knowledge, providing a key advance that will greatly facilitate the preclinical development of novel treatments for this disease.

A case report of midgut atresia and spontaneous closure of gastroschisis.

We report a case in which a neonate with a prenatal diagnosis of gastroschisis was born with midgut atresia and the mummified remains of the midgut arising from a spontaneously closed abdominal wall defect. As our ability to prenatally diagnose abdominal wall defects has improved, we have gained some insight into the prenatal natural history of this pathological process. We present a case in which an abdominal wall defect spontaneously closed and was associated with an apparent in utero midgut vascular accident. This unusual case provides some insight into the mechanisms underlying the pathophysiology of gastroschisis.
