Abstract
BACKGROUND Emergency care staff wearing elastomeric respiratory personal protective equipment (PPE) report difficulties in communicating by telephone. We developed and tested an affordable technological solution aimed at improving telephone call intelligibility for staff wearing PPE. METHODS A novel headset was created to enable a throat microphone and bone conduction headset to be used in combination with a standard hospital 'emergency alert' telephone system. Speech intelligibility of an ED staff member wearing PPE was compared between the proposed headset and current practice by simultaneously recording a version of the Modified Rhyme Test and a Key Sentences Test. Recordings were played back to a group of blinded ED staff listening to pairs of recordings under identical conditions. The proportion of correctly identified words was compared using a paired t-test. RESULTS Fifteen ED staff correctly identified a mean of 73% (SD 9%) words for speech communicated via the throat microphone system, compared with only 43% (SD 11%) of words for standard practice (paired t-test, p<0.001). CONCLUSIONS Introduction of a suitable headset could significantly improve speech intelligibility during 'emergency alert' telephone calls.

Abstract
Les risques terroristes nucléaires, radiologiques, biologiques et chimiques (NRBC) constituent une menace permanente. Les primo-intervenants seront probablement des personnels non spécialisés face à un événement de cette nature. À l’extérieur ou à l’accueil des hôpitaux, leur rôle sera pourtant décisif sur le plan tactique afin de mettre en œuvre les premières mesures et minimiser les effets sur la population. Acquérir et entretenir un niveau de formation suffisant pour un risque d’occurrence rare, pour agir efficacement en tenue de protection dans un contexte aussi stressant sont des défis pédagogiques et organisationnels pour nos services. En 2019, la brigade de sapeurs-pompiers de Paris conceptualise la « chaîne de survie NRBC » regroupant les cinq actions essentielles à mener par les primointervenants en cas d’événements NRBC. Ces tâches, indissociables, sont représentées sous la forme d’une chaîne constituée de cinq maillons : 1) Décontamination d’urgence pour limiter l’intoxication et la contamination ; 2) Recherche de symptômes pour identifier l’agent et alerter les secours ; 3) Administration précoce des traitements pour réduire la morbi mortalité ; 4) Décontamination approfondie pour protéger le système de santé ; 5) Évacuation vers l’hôpital. En 2020, l’acronyme « DUST DAHO » est ajouté pour optimiser la mémorisation et la restitution des cinq maillons de cette chaîne. Cet outil cognitif s’adresse à tous les acteurs, soignants ou non, à l’extérieur ou à l’accueil de l’hôpital, quel que soit l’agent NRBC en cause. Il pourrait également être un outil de communication précieux pour le grand public en cas de crise.

Round M, Isherwood P. Speech intelligibility in respiratory protective equipment - Implications for verbal communication in critical care. TRENDS IN ANAESTHESIA AND CRITICAL CARE 2021; 36:23-29. [PMID: 38620262 PMCID: PMC7428718 DOI: 10.1016/j.tacc.2020.08.006] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/19/2020] [Revised: 08/12/2020] [Accepted: 08/13/2020] [Indexed: 11/20/2022]
Abstract
Respiratory protective equipment (RPE) such as filtering facepiece respirators, elastomeric respirators and powered air-purifying respirators are routinely worn in the critical care unit as a component of personal protective equipment (PPE) when caring for patients with coronavirus disease 2019 (COVID-19). It is the authors' anecdotal experience that RPE may, however, inadvertently interfere with verbal communication between critical care staff. The literature pertaining to the effects of RPE wear on verbal communication was therefore reviewed. A literature search returned 98 articles, and 4 records were identified from other sources; after screening for content relevancy, 15 experimental studies were included in the narrative synthesis. Previous studies in both healthcare and other occupational settings suggest a detrimental impact on speech intelligibility, varying according to RPE type and test conditions. The effects of background noise and potential for increased cognitive load through compensatory behaviours are also identified. The clinical significance of these effects remains uncertain though, as evidence measuring clinical outcomes or errors is lacking. Mitigating strategies include increasing speech intelligibility through environmental changes and technology; modifying verbal communication strategies; and decreasing reliance on verbal communication where possible.
