Knowledge of genetics of hearing and genetic counseling among practicing audiologists

Abstract

IntroductionHearing loss occurs during various periods of life. Around half of the world's hearing loss is considered to be inherited or genetic. Audiologists play a key role in educating the patient/family about the origin of hearing loss and counseling on genetic aspects of hearing. Genetics has been part of the curriculum in India for the specialised master’s degree in audiology since 2009. There is a need to investigate the impact of this course on the field of knowledge and practice of hearing genetics among audiologists. In this study, we examined the knowledge and practice of genetics of hearing among audiologists practicing in India. In addition, we compared graduates who learnt genetics in their curriculum with graduates who did not.MethodA thirty-six-point questionnaire was developed based on clinical and research studies conducted hitherto and inputs from practicing geneticists. The survey consists of five domains. 133 audiologists participated in the study.ResultsBased on percentage analysis, overall knowledge and practice of the genetics of hearing among the audiologists were not adequate in certain aspects of the genetics of hearing (inheritance pattern and genetic counseling). There were no significant differences in knowledge and practice between audiologists based on educational qualifications and work experience.ConclusionThis novel study compared knowledge of audiologists and practice based on their work experience and educational qualifications. The present study reported that the majority of audiologists were interested in updating their knowledge about the genetics of hearing.
