Title: Optimising newborn nutrition during therapeutic hypothermia: an observational study using routinely collected data - REC Reference: 17/EM/0307
Chief Investigator: Chris Gale
Duration: September 2017 - June 2019
This is a NIHR funded retrospective study that aims to determine the optimum enteral and parenteral nutrition strategy for infants with Hypoxic Ischaemic Encephalopathy (HIE), during and after therapeutic hypothermia. It is led by Dr Chris Gale, a neonatal consultant at Chelsea and Westminster Hospital NHS Foundation Trust and a Clinical Senior Lecturer at Imperial College London.
The study will use population level data held within the NNRD to examine the association between different feeding strategies and outcomes such as necrotising enterocolitis, and between different parenteral nutrition strategies and outcomes including bloodstream infection. The study will adjust for illness severity using propensity score matching. More details about the study can be found in the protocol

The purposes of the study are to test one hypothesis that preterm birth and neuropsychiatric disorders share the same genetic risk factors (objective 1) and to conduct a pilot investigation that will inform future large-scale studies utilising the NNRD to investigate the relationships between very preterm birth, genetics and neuropsychiatric disorders (objective 2).
Prevail - REC Reference: 14/LO/1965
The Prevail study is led by Dr Sam Oddie, Consultant Neonatologist Bradford Royal Infirmary. The study will link data from the National Neonatal Research Database (NNRD) with data submitted by microbiology laboratories to PHE. The purpose is to monitor risk-adjusted rates of bloodstream infection across neonatal units in England in order to determine the generalisability of outcomes of the NIHR funded PREVAIL study (PREVenting infection with Antimicrobial Impregnated Long lines). The data will be sent to PHE where linkage with laboratory data will take place resulting in the creation of a national resource comprising NNRD data linked with the date and results of blood cultures submitted by microbiology laboratories to PHE.

The impact of inter-hospital transportation: Neonatal outcomes and implications for
families - REC reference: 17/LO/1822
The study is led by Dr Don Sharkey, Faculty of Medicine and Health Sciences, School of Medicine, Division of Child Health,
Queen’s Medical Centre, Nottingham.
The study will use population level data held within the NNRD to examine the patterns of transfers in the UK in recent years and the potential impact this has on families in terms of the time away from their booking hospital. The study will also look at a defined group of babies, those with hypoxic-ischaemic encephalopathy, to see how delivery of therapeutic hypothermia is evolving in the UK and if there are any changes in short-term outcomes observed with inter-hospital transfer.

Inhaled nitric oxide (iNO) - REC reference: 16/WS/0228
The iNO (Inhaled nitric oxide) study’s Chief Investigator is Nimish Subhedar, Neonatologist, Liverpool Women’s Hospital. Dr Chris Gale, Senior Lecturer, Imperial College, London and Eugene Statnikov, Senior Data Manager, Neonatal Data Analysis Unit, Imperial College, London are Co-investigators.
Inhaled nitric oxide (iNO) is widely used in the treatment of hypoxaemic respiratory failure and persistent pulmonary hypertension of the newborn. Although a well-established therapy in term and near-term infants, its use in preterm infants < 34 weeks’ gestation remains controversial. Population based data indicates that there is wide variation in administration rates amongst US hospitals, but there is no equivalent data from the UK or mainland Europe [1-4]. Data from individual centres and multicentre studies suggests that the use of iNO is increasing in recent years, especially in preterm infants, despite the lack of a clear evidence base in this population.
The iNO study aims to describe hospital variation in patient demographics and treatment rates relating to the use of inhaled nitric oxide in term and preterm infants admitted to neonatal units in England.

NeoNet – REC Reference: 15/NW/0503
The aim of NeoNet, led by Professor Martin Pitt, Associate Professor of Healthcare Modelling and Simulation, University of Exeter Medical School, is to develop a computer model of demand and capacity for neonatal care in England. The model runs through simulated time and predicts variation in unit workload, periods of overload and unit closure, number and distances of required transfers, and distances from the parent’s home location to the location of care of the infant. Infants are born in the model with varying needs; they may access specialist surgical/cardiac services, intensive care, high dependency care, special care and transitional care. The number, location, type and size of units may be varied and the impact on service providers and parents predicted. This national model builds on a previous regional model developed for the South West Peninsula Region.

UK Neonatal Collaborative Necrotising Enterocolitis Study: using operational clinical data captured electronically at the point of care for surveillance and research: UKNC - NEC Study - REC ref: 11/LO/1430
Lead: Dr Cheryl Battersby, Imperial College, firstname.lastname@example.org
Background: There is a poor understanding of the epidemiology, multi-factorial aetiology and pathophysiology of NEC. Strategies for prevention remain elusive, making this an issue of prime importance for neonatal care. There are scant population incidence data, most previous studies have reported by birth weight categories rather than gestational age, and case-definitions have been inconsistent. Interventional studies require good baseline data and an objective case-definition.

- To determine the population incidence of NEC in England
- To identify enteral-feed related factors that precede onset of NEC in order to inform the design of future interventional randomised controlled trials
