Positive Impact of an Educational Brochure on Follow-Up for a Formal Hearing Evaluation.

Abstract

Half of older persons experience serious hearing loss, yet it remains under-assessed in primary care clinics. Providers note time constraints as barriers and patients often minimize or deny their hearing loss. We tested the effectiveness of a simple hearing screen in primary care settings and whether including a brochure describing hearing loss, its consequences, and treatment would increase referrals for formal audiometric assessments. We designed a longitudinal effectiveness study assessing three interventions: Screening alone; Screening plus a brochure handed to the person testing positive; and Screening plus the brochure with a brief review. The screening was accomplished by intake personnel. The results of a positive screen were given to the primary care practitioner. The approach was designed to enable its use across a range of primary care settings. Follow-ups occurred at 4 and 8 months. A total of 111 older adults attending 7 primary care clinics screened positive for having possible hearing loss by intake personnel. A total of 46 received the educational brochure. Physicians discussed test results with two-thirds yet recommended further testing for only half of the participants. Physician recommendations were strongly motivating (OR = 9.12, 95% CI: 3.54-23.52) and those receiving the brochure were still more likely to seek further testing (OR = 2.61, 95% CI: 1.07-6.36) even when physician recommendations were controlled. Additionally, when combined, the 2 options were strongly motivating: all participants receiving both a referral and a brochure sought further testing. A simple screen and educational brochure on hearing loss improved follow-up for a formal hearing evaluation which may improve hearing health care and minimize negative outcomes. The study also identified barriers to implementation, including how to motivate practitioners and assist intake personnel in integrating hearing screening into their routine intake procedures, supporting further research.
