PurposeThe difficult airway cart is essential for difficult airway management. Recognition of the importance of human factors in critical scenarios promoted the evolution of the difficult airway cart. Limitation to essential equipment, a structured layout, and proper labelling should be observed. We sought to redesign the difficult airway cart accordingly and analyze how perioperative professionals reacted to it.MethodsWe conducted a two-phase prospective qualitative improvement project involving a multidisciplinary team. In phase 1, we reconfigured our difficult airway cart, including developing icons for labelling the drawers and discussing the equipment content. In phase 2, we delivered a multidisciplinary educational program and pre- and postsession questionnaires were administered to the professionals involved and compared.ResultsPhase 1 of the project encompassed 21 participants. We presented the final layout and content of the difficult airway cart. In phase 2, 44 participants responded the presession questionnaires, and 30 participants answered the postsession questionnaires. The results showed that the new design and the implementation program increased the comfort level of professionals involved in a potential airway crisis (presession mean [standard deviation (SD)]: anesthesiologists, 8.0 [1.9]; anesthesia assistants/respiratory therapists [AAs/RTs], 9.3 [0.8]; operating room registered nurses [OR RNs], 6.3 [2.7]; P = 0.001; postsession: anesthesiologists, 8.5 [2.0]; AAs/RTs, 9.6 [0.5]; OR RN, 7.9 [2.0]; P = 0.10). Nevertheless, the improvement was only statistically significant among the OR RNs (presession mean [SD]: 6.3 [2.7]; postsession: 7.9 [2.0]; P = 0.01). Additionally, the program facilitated the recognition of the location of airway equipment in the airway cart (positive responses ranging from 97% to 100%).ConclusionOur quality improvement project successfully designed and implemented a new visual-based difficult airway cart at our institution. We believe this report enables other institutions to reproduce our project.© 2024. Canadian Anesthesiologists' Society.
