According to the Report of the Croatian Institute of Public Health in 2019, there were 13,133 people with hearing impairments in Croatia. The most common place of impairment is the cochlea. Cochlear damage, when possible, is treated mainly by implanting an artificial cochlea. After implantation, a person must undergo hearing rehabilitation, and like other hearing impaired people, he or she will often be stigmatized. Nurses and technicians play an important role here because in most cases they are closest to the patient. Therefore, the aim of this study was to collect and analyze data on the perception of nurses and technicians on artificial cochlear implantation, rehabilitation, and access for people with hearing impairments. In order to conduct the research, a survey was conducted in which 562 respondents (93.1% women and 6.9% men) were divided into four age categories. Most respondents (35%) were in the category of 31-40 years, followed by the category 30 years (29%), category 41-50 years (20%) and >50 years (16%). Considering the level of vocational education, the largest percentage of respondents (46.1%) had a university degree, followed by secondary education (38.4%) and finally higher education (15.5%). The influence of education and age on general and specific knowledge about patients with artificial cochlea, as well as on the knowledge of sign language and attitudes about hearing impaired people, was examined on the mentioned sample by the Kruskal-Wallis H test. The results show that for certain knowledge there is a statistically significant difference depending on the level of education, but it is not possible to conclude that people with higher education give more accurate answers, as some questions were more often answered correctly by those with secondary education and some by those with higher or higher. The same goes for age. It was found that younger people with secondary education know sign language better (P ≤ 0.001), but also that there is no difference in the impact of education and age on the stigmatization of hearing impaired people where 72.4% of respondents believe that such people are stigmatized. This research can be considered a pilot study which is a good starting point for more extensive research with a more precise and professionally set survey, as there are clear indications of how the level of education affects general knowledge about artificial cochlea and perception of hearing impaired people.
