Research summary
Naso-gastric (NG) tubes (a tube passed through a patient’s nostril into their food pipe and then stomach, secured to the patient’s cheek with tape) are widely used in the NHS for adult and child patients to provide enteral feeds or medicines for patients who cannot swallow or tolerate feeds by mouth, or patients requiring intensive care/surgery.\n\nThere are patient safety concerns if an NG-tube becomes misplaced into the patient’s lung during insertion, or moves out of the patient’s stomach at a later stage. Feeding through a misplaced NG-tube can can cause serious harm to patients, even death.\n\nThe current procedure for testing correct placement of an NG-tube relies upon getting gastric aspirate up an NG-tube for testing with pH paper, but only 50-85% success rates are reported for getting aspirate. When aspirate cannot be obtained, X-rays are used to verify NG-tube position. However, X-rays are costly and inconvenient for patients, and also subject to misinterpretation. Something better is needed.\nThis study builds upon our earlier research and is part of a programme of work that aims to develop and test a new portable, hand-held device (known as NG-Sure®) to detect the correct position of a naso-gastric tube (NG-tube) in adult patients.\n\nNG-Sure® will identify the location of an NG-tube through the measurement of pH and volatile organic compounds (VOCs) emanating from the stomach (or in the case of NG-tube misplacement, from the lungs, trachea or oesophagus).\n\nThis particular study aims to: i) understand user requirements of the NG-Sure® device throughout the different stages of development and evaluation through a process of user-centred design (UCD); and, ii) gain insight into the ways NG-tubes are currently used in practice and explore the individual, team, and organisational factors that promote or hinder safe and efficient use of NG-tubes.\n
