Title: Children Oxygen Administration Strategies Trial-Nutrition.


To prevent poor long-term outcomes (deaths and readmissions) for children who are hospitalised with severe pneumonia the integrated global action recommends the importance of continued feeding but gives no specific recommendations for nutritional support. Early nutritional support is practiced in a wide variety of critically ill patients in order to provide vital cell substrates, antioxidants, vitamins, and minerals essential for normal cell function and decreasing hypermetabolism. COAST-Nutrition overarching objective is to investigate whether supplementary feeding for 56-days (8 weeks) using Ready to Use Therapeutic Feeds (RUTF) in addition to usual diet in children aged 6 months or more and without severe acute malnutrition versus usual standard care (usual diet alone) will improve outcome at 90-days and 180 days to provide a better evidence base for future management guidelines. 

The study is an open, multicentre RCT of 840 participants, aged from 6 months to 12 years, admitted to hospital with respiratory distress complicated by hypoxia. Participants will be enrolled over a 36-months period and followed up to 28 days post-randomisation, Day 90 and day 180 (6 months) to assess short and long-term outcomes following admission with pneumonia. Ancillary (sub) studies include molecular characterization of bacterial and viral pathogens, evaluation of putative biomarkers of pneumonia, assessment of muscle and fat mass and host genetic studies. 

Children will be enrolled at admission to hospital from 5 sites in 2 countries (Uganda and Kenya) and followed for 180 days. The trial has a pragmatic design, to ensure this encompasses a spectrum of high-risk children, identified largely by clinical criteria, so that the results are applicable to health services in Africa, with limited access to health technologies. 



Aims and purpose 

Primary objectives 

To establish whether supplementing feeds with RUTF will improve anthropometric outcomes at Day 90 and Day 180.


Secondary objectives 

The key secondary outcome measures are: 

  • Survival to 28 days and 180 days (6 months) 
  • Disability-free survival to 28 days 
  • Re-admission to hospital by 28 and day 180 days 
  • Neurocognitive sequelae at 90 days  
  • Anthropometric status by 28 days, Day 90 and Day 180 (MUAC, TST and WHZ)  

Expected benefits to the society

The trial will investigate and provide evidence to whether nutritional support after severe illness does improve outcome this will provide important new evidence that is both clinically beneficial and important in improving healthcare. This study is the first step in providing an option for nutritional support following severe pneumonia and will help in the design of a large Phase III trial.
