Aim: The priority of this study was to examine the effectiveness of the RHHI (“Revised Hearing Handicap Inventory”) questionnaire in nursing assessment of patient hearing and health care planning for patients with acute hearing loss. Subjects and methods: The research was conducted at the Clinic for ear, nose and throat diseases with head and neck surgery, University hospital center Split. The study involved 32 subjects who met the inclusion criteria: acute hearing loss in the last 72 hours, hearing loss confirmed by tonal audiogram, and medical diagnosis of idiopathic hearing loss. The RHHI questionnaire was used to self-assess the social and emotional consequences of hearing impairment on patients' daily lives, consisting of 18 questions. The research was conducted in the time period from 28.10.2021. to 26.04.2022.. Results: There was no statistically significant difference between the higher scoring score on the constructed RHHI questionnaire and the higher hearing loss score on the audiogram test. Research has shown that sudden idiopathic hearing loss is more pronounced unilaterally. If the hearing impairment measured by the audiogram for the right ear is greater, it will be less in the left ear and vice versa (p=0.030). Clinical assistance was requested mainly by respondents who have ≥ 6 points in the RHHI questionnaire. There was no significant difference in the results of the study between younger subjects with sudden idiopathic hearing loss who had milder hearing impairment than the elderly with the same clinical picture. The results showed that the older age of the patient causes more severe hearing damage in the left ear. An association between the existence of feelings of frustration when communicating with people with idiopathic hearing loss and difficulty attending a party was found (p= 0.028). It has been proven that men and women suffer from idiopathic hearing loss equally. Conclusion: The RHHI questionnaire can have a practical purpose in nursing assessment of patients, allows rapid recognition of individual pathological patterns and solving nursing medical problems. By caring for a patient with acute hearing loss, a nurse will contribute to improving hearing and quality of life.
