Practice developments supporting change implementation in Wellington,New Zealand (NZ) for ‘continuity of care when transitioning complex preterm infants from NICU to home’

The discussion paper will focus on continuity of care relating to previous NZ research, specifically to transitioning complex preterm infants from NICU to home based on parent experiences, and on the practice developments that have occurred, to ensure optimal health outcomes. Previous NZ research discovered parent desire a consistent service delivery for the entire transition journey from NICU and at home.An informative and comprehensive opportunity has occurred for reflective professional practice, evaluation, development and implementation which have transpired in positive change through innovative practice developments and support change implementation in Wellington, NZ. This has resulted in the articulation of a model of care that has both embraced and integrated parental desires for a continuity of care process for complex preterm infants. This has been achieved by having the same Discharge Facilitator/Key Case Manager present within the NICU and external to the NICU for Home-based infants for the entire transition journey.The paper will focus and emphasis additional practice development changes and furthermore, will present a real purpose, for other countries to learn of such practice developments that have exemplified a celebratory success for families of Wellington, NZ.     

全身运动质量评估指导高危儿早期干预的研究

目的 通过比较全身运动(GMs)评估正常的高危儿单纯家庭康复训练与家庭康复训练联合药物干预的预后,分析GMs对高危儿早期干预的指导意义。方法 选取2016年2月-2017年2月于潍坊市妇幼保健院康复科就诊并接受GMs评估正常的183例高危儿,随机分组为观察组和对照组,观察组为单纯家庭康复训练组89例,对照组为家庭康复训练联合药物干预组94例。采用Peabody运动发育量表对两组患儿分别于纠正月龄6、9、12个月龄进行评估,对Peabody运动发育量表中各指标应用SPSS 21.0进行统计分析。结果 干预后,纠正月龄6、9、12个月龄时,观察组和对照组Peabody运动发育量表中粗大运动商(GMQ)、精细运动商(FMQ)、总运动商(TMQ)比较,差异无统计学意义(P>0.05),重复测量方差分析发现观察组和对照组的GMQ、FMQ、TMQ评分的组间效应差异无统计学意义(P>0.05),时间效应差异有统计学意义(P<0.05),干预因素与时间因素不存在交互作用(P>0.05)。结论 GMs评估对高危儿早期干预具有指导意义。GMs评估正常者,家庭康复训练可达到促进高危儿运动功能发育的目的 ,避免仅因系高危儿而采取“过度干预”。     

Approaches to understanding and interpreting the risks of red blood cell transfusion in neonates

In this review, we explore how to assess potential harm related to neonatal transfusion practice. We consider different sources of information, including passive or active surveillance systems such as registries, observational studies, randomised trials and systematic reviews. Future research directions are discussed.     

非脑瘫早产儿早期全身运动质量评估结果与神经认知发育情况的关联性研究

目的 了解早期全身运动(GMs)评估结果为异常/可疑的非脑瘫早产儿与筛查正常的早产儿在婴幼儿期神经、认知等各方面整体发育水平的差异,以探索GMs评估与儿童轻微神经功能障碍的关系。方法 选取2009-2017年在上海市闵行区妇幼保健院扭动阶段或不安阶段至少进行过1次GMs评估的早产儿,于矫正后9、12、24月龄评估其智力指数(MI)、发育商(DQ)。结果 单因素分析显示,扭动阶段/不安阶段结果为异常/可疑的非脑瘫早产儿与正常结果相比,MI与DQ差异均无统计学意义(P>0.05);多因素分析显示,不安运动结果为异常/可疑与正常相比,发育异常结局的可能性大(9月龄:OR=3.075,95%CI:1.013~9.331;12月龄:OR=3.638,95%CI:1.552~8.527;24月龄:OR=2.750,95%CI:1.213~6.242);不安运动评估结果对不同年龄发育异常结局预测的灵敏度较低(8.82%~18.60%),特异度较高(＞95%)。结论 GMs评估在预测婴幼儿后期神经、运动发育情况存在局限性,不可取代后续的各类发育评估与监测。     

Quantifying breast milk intake by term and preterm infants for input into paediatric physiologically based pharmacokinetic models

Despite the many benefits of breast milk, mothers taking medication are often uncertain about the risks of drug exposure to their infants and decide not to breastfeed. Physiologically based pharmacokinetic models can contribute to drug‐in‐milk safety assessments by predicting the infant exposure and subsequently, risk for toxic effects that would result from continuous breastfeeding. This review aimed to quantify breast milk intake feeding parameters in term and preterm infants using literature data for input into paediatric physiologically based pharmacokinetic models designed for drug‐in‐milk risk assessment. Ovid MEDLINE and Embase were searched up to July 2, 2019. Key study reference lists and grey literature were reviewed. Title, abstract and full text were screened in nonduplicate. Daily weight‐normalized human milk intake (WHMI) and feeding frequency by age were extracted. The review process retrieved 52 studies. A nonlinear regression equation was constructed to describe the WHMI of exclusively breastfed term infants from birth to 1 year of age. In all cases, preterm infants fed with similar feeding parameters to term infants on a weight‐normalized basis. Maximum WHMI was 152.6 ml/kg/day at 19.7 days, and weighted mean feeding frequency was 7.7 feeds/day. Existing methods for approximating breast milk intake were refined by using a comprehensive set of literature data to describe WHMI and feeding frequency. Milk feeding parameters were quantified for preterm infants, a vulnerable population at risk for high drug exposure and toxic effects. A high‐risk period of exposure at 2–4 weeks of age was identified and can inform future drug‐in‐milk risk assessments.
