ABSTRACT
RATIONALE: Hearing loss is a common problem for older adults entering rehabilitation hospitals. AIMS AND OBJECTIVES: To pilot a hearing loss screening device to determine feasibility, usability, and impact on patient outcomes. METHODS: We screened all patients newly admitted to a geriatric day hospital for hearing loss using the SHOEBOX® QuickTest (SHOEBOX Ltd.) app as part of a quality improvement programme. We measured the time it took for each patient to complete screening and recorded any issues they had using the app. We recorded the number of patients who screened positive who did not have a previous diagnosis and changes in physician behaviours after they received their patients' results. RESULTS: Seventy-four patients with a mean age of 83.4 years used the hearing screener. All patients were able to complete the screening with a mean time to completion of 10 min and 48 s. Ninety-nine percent of patients screened positive for hearing loss. Of these positives 56% were in participants not already known to have hearing loss. Physicians often changed their behaviour after receiving results by using assistive devices during visits and referring to audiology for formal testing. CONCLUSIONS: Screening for hearing loss is feasible in a geriatric day hospital. The SHOEBOX QuickTest app is acceptable, usable, resulting in the identification of undiagnosed hearing loss and in changes to physician behaviour.

BACKGROUND: Hearing loss is the largest potentially modifiable risk factor for dementia and is highly prevalent among older adults, yet it goes largely unreported, unidentified, and untreated, at great cost to health and quality of life. Hearing screening is a proven cost-effective solution to overcome delays in its identification and management yet is not typically recommended by physicians for older adults. OBJECTIVE: To demonstrate the feasibility and value of hearing screening for older adults at risk for dementia in order to enhance physicians' awareness of hearing loss and improve access to timely hearing care. METHODS: Patients referred to two academic medical clinics for memory disorders were offered hearing screening as part of clinic protocol. Patients with hearing loss were recruited to the study if they consented to a post-appointment telephone interview and chart review. Memory Clinic physicians were surveyed about the usefulness of the screening information and referral of patients with hearing loss to audiology. RESULTS: Hearing loss was reliably detected in Memory Clinic patients with both in-office and online screening tools. Physicians reported that screening enhanced their awareness of hearing loss and increased the referral rate to audiology. CONCLUSION: Hearing screening in Memory Clinic patients is a useful component of clinic protocol that facilitates timely access to management and addresses an important risk factor for dementia.

Objectives: The aim of this study was to validate a novel iPad-based rapid hearing loss screening tool (SHOEBOX QuickTest) in individuals with cognitive impairment. Design: Cross-sectional validation study. Setting: Bruyère Research Institute, Ottawa, Canada. Subjects and Methods: Twenty-five individuals with mild cognitive impairment (MCI) and mild dementia from the Bruyère Memory Program were included in this study. The study consisted of two components: (1) SHOEBOX QuickTest hearing screener and (2) a conventional hearing test (pure tone audiometry). Measurements: Hearing was assessed at 1,000, 2,000, and 4,000 Hz separately for each ear. The agreement between hearing ability groupings (good vs. reduced) from conventional hearing test and SHOEBOX QuickTest was determined. Specifically, accuracy, sensitivity, specificity, as well as alignment between conventional thresholds and hearing threshold ranges. Results: An overall accuracy of 84% was observed for SHOEBOX QuickTest, and a sensitivity and specificity of 100 and 66.7%, respectively. 72% ([95% CI], 60.0-84.1%) of conventional audiometry thresholds were within the pre-established 10 dB SHOEBOX QuickTest. Conclusion: SHOEBOX QuickTest is a valid hearing loss screening tool for individuals with cognitive impairment. Implementing this iPad-based screening tool in memory clinics could not only aid in the timely diagnosis of hearing loss, but also assist physicians in providing a better assessment of cognitive impairment by ruling out hearing loss as a confounding variable.
