Key measures include audiogram testing within 2 weeks for distinguishing SSNHL from CHL. For SSNHL patients, MRI or auditory brainstem response (ABR) testing should be obtained, and steroids and\/or hyperbaric oxygen may be offered within 2 weeks.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>There were 24,203 SHL patients, 59.1% (n\u2009=\u200914,309) of whom underwent recommended audiogram testing, with 35.8% (n\u2009=\u20098,674) completing it within 2 weeks. Overall, 3,107 were diagnosed with unilateral SSNHL, 104 with unilateral conductive hearing loss (CHL), 121 with mixed hearing loss, and 10,977 were lost to follow\u2010up. Among 3,107 SSNHL cases, just 25.5% (n\u2009=\u2009791) obtained MRI\/ABR within 1 month, and vestibular schwannoma was diagnosed in 3.5% (n\u2009=\u200928). Additionally, steroids were prescribed to 54.5% (n\u2009=\u20091,692), and &lt;0.3% (n\u2009\u2264\u200910) received hyperbaric oxygen. In accordance with strong recommendations against or insufficient evidence to support the following diagnostics and treatments, 2.0% (n\u2009=\u200963) underwent a CT scan, less than 0.3% (n\u2009\u2264\u200910) were prescribed vasodilators or thrombolytics, and 3.5% (n\u2009=\u2009108) were on antivirals.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>There is a significant opportunity for improvement in evaluating patients with SHL, specifically SSNHL.
