Regional Distribution Of The Cochlear Implant (Ci) Centers In Germany

The treatment of patients with severe hearing loss or deafness with a cochlear implant (CI) represents a standard in Germany today. However, there is hardly any data on the current number of clinical CI centers (CI clinics) and their geographical distribution. The patient self-help organization, German Cochlear Implant Society (DCIG), and the German Society for Otorhinolaryngology, Head and Neck Surgery (DGHNO-KHC) have therefore initiated a survey to determine the regional distribution, the range of services, the consideration of existing quality standards and cooperation with patient self-help organizations of the individual clinical CI centers.For this purpose, a total number of 170 ENT departments or their directors (37 professors and 133 chief physicians), respectively, were contacted by e-mail and provided with a questionnaire. The survey took place from October 2019 to February 2020.Of the 170 departments contacted, 71 (41.8%) took part in the survey. Of these, 70 departments (98.6%) confirmed to perform CI surgeries. Thus, 41.8% of all clinics contacted reported to perform CI surgeries (70 of 170 clinics), while this information was not available from 99 clinics. All 70 clinical CI centers (100%) reported to conduct CI surgeries on adults, 60 centers (85.7%) also on children (<18 years). 36 departments (51.4 %) reported that the total number of CI surgeries at their facility in 2018 was more than 50. In 64 departments (91.4 %), the recommendations of the DGHNO-KHC on CI care (according to the White Paper CI care 2018) were followed. A collaboration between the department and patient self-help organization was confirmed by 67 institutions (95.7 %). The geographical distribution of the clinical CI centers showed a heterogeneous distribution pattern between the individual federal states and also within the respective federal state.The work presented here is a first assessment of the situation with regard to the regional distribution of clinical CI centers in Germany. A clustering of CI centers was noticeable in metropolitan areas, sometimes with several facilities in one city. The predominant attention to quality-related aspects, such as the consideration of the DGHNO-KHC white paper and the cooperation with patient self-help, is gratifying. The limitations of the study result from limited participation in the survey (41.8% of the contacted clinics).
