Abstract
Background The use of automatic external defibrillators (AEDs) by lay rescuers can reduce the time to defibrillation and improve survival in out-of-hospital cardiac arrest (OHCA). AEDs use voice prompts to guide users through the defibrillation process, creating a potential barrier for deaf and hard-of-hearing (HoH) individuals. The objective of this study is to assess familiarity with and concerns regarding AED use among members of these communities. Methods A 19-question Qualtrics survey was distributed to adults in the United States who self-identified as deaf or HoH. The questions included seven demographics, eight yes/no/unsure, three Likert scales, and one multiple-response question. Quantitative analysis was performed using 95% confidence intervals to compare familiarity with and concerns about AED use among deaf, HoH, and combined groups of respondents. Results Of the responses, 500 met the inclusion criteria; 130 (26%) self-identified as deaf, and 370 (74%) self-identified as HoH. Around 460 (92%) were in the 18-40 age group. AED recognition was high among both deaf (90.77%) and HoH (84.59%) respondents, though deaf respondents were less likely than HoH respondents to have seen an AED in a public place (p=0.03) or know how to safely use one (p=0.001). In both the deaf and HoH groups, the top concern regarding AED use was that AEDs were too technical or complicated (61.86% and 56.8%). Of all respondents, 36.4% reported that AEDs were not user-friendly (p=0.034). All participants identified some concerns regarding AED use in emergencies. In addition, 56.15% of deaf and 39.19% of HoH respondents were concerned that AED use is potentially dangerous (p<0.001). There was no statistically significant difference between the two groups in knowing when to use an AED or where to find more information about AEDs. Conclusion Deaf and HoH people have specific concerns about AEDs, including the safety and complexity of operating an AED and the accessibility (user-friendliness). In this study, the deaf population is less familiar with using an AED than the HoH population. Possible interventions to address concerns of the deaf and HoH communities include AED training given in American Sign Language (ASL) and updating AED designs with improved visual and non-verbal directions.
