The Medicare annual wellness visit: An opportunity to improve health system identification of hearing loss?

Background

Hearing loss is prevalent and consequential but under-diagnosed and managed. The Medicare Annual Wellness Visit (AWV) health risk assessment elicits patient-reported hearing concerns but whether such information affects documentation, diagnosis, or referral is unknown.

Methods

We use 5 years of electronic medical record (EMR) data (2017–2022) for a sample of 13,776 older primary care patients. We identify the first (index) AWV indication of hearing concerns and existing and subsequent hearing loss EMR diagnoses (visit diagnoses or problem list diagnoses) and audiology referrals. For a 20% random sample of AWV notes (n = 474) we compared hearing loss EMR diagnoses to documentation of (1) hearing concerns, (2) hearing loss/aid use, and (3) referrals for hearing care.

Results

Of 3845 (27.9%) older adults who identified hearing concerns (mean age 79.1 years, 57% female, 75% white) 24% had an existing hearing diagnosis recorded. Among 474 patients with AWV clinical notes reviewed, 90 (19%) had an existing hearing loss diagnosis. Clinicians were more likely to document hearing concerns or hearing loss/aid use for those with (vs. without) an existing EMR diagnosis (50.6% vs. 35.9%, p = 0.01; 68.9% vs. 37.5%, p < 0.001, respectively). EMR diagnoses of hearing loss were recorded for no more than 40% of those with indicated hearing concerns. Among those without prior diagnosis 38 (9.9%) received a hearing care referral within 1 month. Subgroup analysis suggest greater likelihood of documenting hearing concerns for patients age 80+ (OR:1.51, 95% confidence interval [CI]: 1.03, 2.19) and decreased likelihood of documenting known hearing loss among patients with more chronic conditions (OR: 0.49, 95% CI: 0.27, 0.9), with no differences observed by race.

Conclusion

Documentation of hearing loss in EMR and AWV clinical notes is limited among older adults with subjective hearing concerns. Systematic support and incorporation of hearing into EMR and clinical notes may increase hearing loss visibility by care teams.
