A Systematic Review of Enteral Feeding By Nasogastric Tube in Young People With Eating Disorders
Abstract BackgroundAdolescents with severe restrictive eating disorders often require enteral feeding to provide lifesavinglifesaving treatment.Nasogastric feeding (NGF) is a method of enteral nutrition often used in inpatient settings to treat medical instability, to supplement minimal poor oral intake or to boostincrease nutritional intake. This systematic review sets out to describe current practice for of NG in young people with eating disordersF. MethodsA systematic review following PRISMA guidelines was conducted by searching AMED, EMBASE and MEDLINE databases from 2000-2020. Inclusion terms were: enteral feeding by nasogastric tube, under 18 years, eating disorders, and primary research. Exclusion terms: mental disorders other than eating disorders; non-primary research; no outcomes specific to NG feeding and participants over 18 years. Titles and abstracts were screened by all authors before reviewing full length articles. Quality assessment, including risk of bias, was conducted by all authors. Results29 studies met the full criteria. 86% of studies were deemed high or medium risk of bias due to the type of study: 34.4% retrospective cohort and 10.3% RCT; 17.2% were qualitative. Studies identified 1) a wide range of practices in different countries, settings, and the reason for initiation; 2) In the UK, standard practice is to introduce Nasogastric feeds (NG) if medically unstable or oral intake is inadequate; 3) NG may enable greater initial weight gain due to increased caloric intake; 4) there are 3 main types of feeding regime: continuous, nocturnal and bolus; 5) high calorie feeds are not typically associated with increased risk of refeeding syndrome; 6) complications included nasal irritation, epistaxis, electrolyte disturbance, distress and tube removal; 7) length of stay in hospital is dependent on reason of initiating NG; 8) psychiatric and medical wards differ in approach; 9) therapeutic interventions can occur alongside NG.ConclusionsA large number of studies were deemed to have a high risk of bias and no studies were able to provide a direct comparison between continuous, nocturnal or bolus NG feeds. This review highlights the need for further high quality research in this area.
