Northern Territory difficult airway trolley audit

Equipment deficiencies are recognised as a major contributor to airway morbidity and mortality, and previous audits conducted in Australia, 1 New Zealand 2 and the United Kingdom 3 have demonstrated poor availability or organisation of difficult airway equipment.The immediate availability and organisation of difficult airway equipment is essential for all critical care units.Equipment should be organised in a logical fashion, and standardised to enable shared learning and facilitate teamwork and processes between sites and operators.Following ethics approval (Top End Health Services HREC 2018-3095, the Central Australian HREC CA-18-3196), we audited difficult airway trolleys (DATs) in the Northern Territory (NT) against standards set by the Australian and New Zealand College of Anaesthetists 4 and the Difficult Airway Society (DAS).5 Seven out of the eight hospitals offering anaesthesia, emergency department (ED), or intensive care unit (ICU) services in the NT were surveyed regarding their DATs.The trolleys were scored according to the presence or absence of essential and non-essential equipment and storage conditions.The scores were converted into percentages and analysed using descriptive statistics.Of the 15 trolleys examined, seven were in theatre suites, six in EDs and two in ICUs.Theatre trolleys were the best equipped, with median scores of 88.9% and 37.5% for essential and non-essential equipment, respectively.ICU trolleys had the best organisation, with a median score of 100% for storage conditions.The median score for essential equipment was 77.8%, with a low score of 61.1% and a high score of 94.4%.Each trolley scored 100% for the items multiple endotracheal tubes, bougies and scalpels.No trolley had an oesophageal detection device.Non-essential equipment had a median score of 42.9%, with a low of 14.3% and a high of 57.1%.Every department had ready access to a videolaryngoscope.Combitubes V R (ETC, Kendall-Sheridan Catheter Corp., Argyle, NY, USA), double-lumen endotracheal tubes and light wands were not available on any trolley.Figure 1 shows the availability of equipment.The median score for storage conditions of difficult airway equipment was 87.5% with a low of 12.5% and
