Impact of discharge criteria on the length of stay in preterm infants: A retrospective study in Japan and Finland.

BACKGROUND: To shorten the hospital stay in preterm infants, it is important to understand the factors extending the length of stay. AIMS: To understand how different discharge criteria affect the length of stay in preterm infants. STUDY DESIGN: A retrospective comparison study. SUBJECTS: Preterm infants born at 28 to 31 gestational weeks in 2020-2021 in a Level IV NICU in Japan (n = 22) and a Level III NICU in Finland (n = 49). OUTCOME MEASURES: We compared the most common last discharge criteria and the postmenstrual age (PMA) between the two NICUs. The potential extending effects of each discharge criterion on the length of stay were also evaluated. The discharge criteria were classified into six categories: temperature, respiration, feeding, examination, weight limit, and family readiness. RESULTS: The PMA at discharge was significantly higher in Japan than in Finland: median 40.7 (interquartile range 39.9-41.3) vs. 37.9 (36.9-39.0) weeks; r = 0.58; p < 0.001. The most common last discharge criterion was the family criterion in Japan (n = 19; 86 %) and the respiration criterion in Finland (n = 43; 88 %). In Japan, the length of stay was extended by 7.9 (standard deviation [SD] 7.0) days due to a lack of family readiness for discharge and 8.7 (SD 8.7) days due to not having discharged home with a feeding tube as a common practice. CONCLUSIONS: The length of stay of preterm infants in Japan could be notably reduced by supporting the parents' earlier readiness for discharge and allowing tube feeding at home.

Close Collaboration with Parents Affects the Length of Stay and Growth in Preterm Infants: A Register-Based Study in Finland.

INTRODUCTION: This study aimed to evaluate how Close Collaboration with Parents (CC), a neonatal intensive care unit (NICU)-wide educational model for healthcare staff to improve their family-centred care practices, affects the length of stay (LOS), growth, and later hospital visits and rehospitalizations of preterm infants. METHODS: This register-based study included all preterm infants born below 35 weeks of gestation in Finland from 2006 to 2020. Eligible infants were classified into the Full Close Collaboration (Full-CC) group (n = 2,104) if the NICUs of both the delivery and discharge hospitals had implemented the intervention; into the Partial-CC group (n = 515) if only one of the NICUs had implemented the intervention; and into the control group (n = 11,621) if neither had implemented the intervention. RESULTS: The adjusted LOS, the primary outcome, was 1.8 days or 6% shorter in the Full-CC group than in the control group (geometric mean ratio 0.94, 95% confidence interval [95% CI] 0.89-1.00). Growth was better in the Full-CC group compared to the control group: adjusted group difference 11.7 g/week (95% CI, 1.4-22.0) for weight, 1.3 mm/week (95% CI, 0.6-2.0) for length. The Full-CC group infants had lower odds of having any unscheduled outpatient visits compared to the control group (adjusted odds ratio 0.81; 95% CI, 0.67-0.98). No significant differences were found in any other comparisons. DISCUSSION/CONCLUSION: The unit-wide intervention improving family-centred care practices in NICUs may lead to more efficient use of hospital resources by shortening the LOS, improving growth, and decreasing hospital visits of preterm infants.

Neurodevelopment and physical measurements in infants with birthweight of 500 grams or less.

BACKGROUND: In infants born weighing ≤500 g, little has been studied about the association between neurodevelopmental prognosis and growth. This study aimed to evaluate the association between neurodevelopmental impairment (NDI) and z-scores of physical measurements in infants born weighing ≤500 g. METHODS: A single-center, retrospective cohort study in a level IV neonatal intensive care unit in Japan. Infants born weighing ≤500 g between 2010 and 2019 were eligible. Z-scores in weight, length/height, and head circumference at birth, due date (or discharge), 6 and 18 months of corrected age, and 3 years of age were compared between infants with and without NDI at 3 years of age. Three infants with severe intraventricular hemorrhage or periventricular leukomalacia were excluded from the comparison analyses. NDI was defined as having a developmental quotient of ≤70, cerebral palsy, visual impairment, or hearing impairment. RESULTS: Of 22 eligible infants, the incidence of NDI at 3 years of age was 54.5%. The z-score was significantly smaller in the NDI group (n = 10) than that in the non-NDI group (n = 9) in head circumference at birth (median, -1.94 vs. -0.75; Z = 0.54; p = 0.020), and in height at 18 months of corrected age (median, -2.84 vs. -1.79; Z = 0.58; p = 0.013) and 3 years of age (median, -2.02 vs. -1.21; Z = 0.47; p = 0.046). CONCLUSIONS: NDI at 3 years of age was associated with a small head circumference z-score at birth, height at 18 months of corrected age, and height at 3 years of age in infants born weighing ≤500 g.

Depressive symptoms in mothers of preterm infants before and during COVID-19 restrictions in neonatal intensive care units.

AIM: Little is known about the specific restriction measures used in intensive care units (NICUs) during the COVID-19 pandemic and their impact on parental well-being. Hence, this study aimed to assess the association between restriction measures and mothers' post-partum depressive symptoms. METHODS: This comparative cohort study included mothers who gave birth before 35 weeks of gestation in Estonia. The outcome measure was mothers' post-partum depressive symptoms at the time of infant discharge, evaluated using the Edinburgh Postnatal Depression Scale (EPDS). In addition to the pandemic itself, the number of restriction measures in the NICUs was analysed as a potential explanatory factor for depressive symptoms. RESULTS: The study included 55 mothers before the pandemic in 2018-2019 and 54 mothers during the COVID-19 pandemic in 2021. No significant difference was found in the median EPDS scores between the cohorts: 7.0 [interquartile range (IQR): 4.0-12.0] and 8.0 (IQR: 5.0-12.8) respectively. The number of restriction measures was not associated with mothers' EPDS scores in either unadjusted or adjusted models. CONCLUSION: The COVID-19 pandemic or the number of restriction measures used in Estonian NICUs did not associate with mothers' post = partum depressive symptoms.

Respiratory and Gastrointestinal Management of an Infant with a Birth Weight of 258 Grams.

Today, more infants weighing less than or equal to 300 g are born, and they survive because of the improvements in neonatal care and treatment. However, their detailed clinical course and neonatal intensive care unit management remain unknown due to their low survival rate and dearth of reports. A male infant was born at 24 weeks and 5 days of gestation and weighed 258 g. The infant received 72 days of invasive and 92 days of noninvasive respiratory support, including high-frequency oscillatory ventilation with volume guarantee and noninvasive neurally adjusted ventilatory assist. Meconium-related ileus was safely treated using diatrizoate. Although the infant was diagnosed with severe bronchopulmonary dysplasia and retinopathy of prematurity requiring laser photocoagulation, he had no other severe complications. He was discharged 201 days postdelivery (3 months of corrected age) with a weight of 3.396 kg. Although managing infants weighing less than or equal to 300 g is difficult, our experience shows that it is possible by combining traditional and modern management methods. The management of such infants requires an understanding of the expected difficulties and adaptation of existing methods to their management. The management techniques described here should help improve their survival and long-term prognosis.

Extrarenal Nephroblastoma of the Retroperitoneal Space in Children: A Case Report and Review of the Literature.

Extrarenal nephroblastoma (ERNB) is a rare disease. We report a case of ERNB in a 4-year-old boy complaining of abdominal pain and vomiting. Imaging showed a retroperitoneal mass and left hydronephrosis. The mass was completely removed by surgery. The pathologic diagnosis was ERNB with favorable histology. Postoperative chemotherapy was administered for 24 weeks with actinomycin D, vincristine, and doxorubicin. No signs of recurrence were found for the next 3 years. We consider 53 reports of ERNB and our own. Median age at diagnosis was 42 months. The most common site is the retroperitoneal space (44.4%), followed by the uterus (14.8%).
