We compared ear\/hearing self-triage subsequent diagnoses to ear\/hearing visit diagnoses in emergency departments (ED) and ambulatory clinics across the United States. <\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p> We compared International Classification of Diseases version 10 (ICD10) coded diagnoses following online self-triage for ear\/hearing concerns with those from national ED and ambulatory clinic samples. We used data from the Centers for Disease Control (CDC) National Hospital Ambulatory Medical Care Survey (NHAMCS) and National Ambulatory Medical Care Survey (NAMCS) for comparison. Using matched ear\/hearing diagnostic categories for those aged 1 and over, we compared self-triage diagnosis frequencies with national ED and ambulatory diagnosis frequencies. <\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p> Following ear\/hearing self-triage, there were 1092 subsequent office visits with a primary diagnosis code. For five frequently diagnosed ear\/hearing conditions (i.e., suppurative and nonsuppurative otitis media [OM], otalgia, otitis externa, and cerumen impaction), there was a strong correlation between diagnosis counts made following self-triage and estimated counts of national ED visit diagnoses (r\u2009=\u20090.94; CI 95% [0.37 to 0.99]; p\u2009=\u2009.016, adjusted r<jats:sup>2<\/jats:sup>\u2009=\u20090.85). Seven diagnoses were available to compare with the national ambulatory sample; correlation was r\u2009=\u20090.79; CI 95% [0.08 to 0.97]; p\u2009=\u2009.037, adjusted r<jats:sup>2\u2009<\/jats:sup>=\u20090.54. For ages 1 and over, estimated hospital admissions from the national ED visits for ear\/hearing were 0.76%, CI 95% [0.28-2.1%]; estimated total national ear\/hearing ED visits were 7.5 million (for 4 years, 2016 through 2019). <\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p> The strong correlation of ear-related self-triage diagnoses with national ED diagnoses and the low hospitalization risk for these diagnoses suggests that there is an opportunity for self-triage of ear\/hearing concerns to decrease ED visits for these symptoms. <\/jats:p><\/jats:sec>","DOI":"10.1177\/23333928231186209","type":"journal-article","created":{"date-parts":[[2023,7,26]],"date-time":"2023-07-26T06:49:06Z","timestamp":1690354146000},"update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":3,"title":["Online Self-Triage of Ear or Hearing Concerns in a Patient Portal: Comparison of Subsequent Diagnoses and Hospitalizations  to National Emergency Department and National Ambulatory Ear or Hearing Visits"],"prefix":"10.1177","volume":"10","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-3696-4595","authenticated-orcid":false,"given":"Frederick","family":"North","sequence":"first","affiliation":[{"name":"Department of Medicine, Division of Community Internal Medicine, Geriatrics, and Palliative Care, Mayo Clinic, Rochester, MN, USA"},{"name":"Primary Care Internal Medicine, Mayo Clinic, Rochester, MN, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Teresa B","family":"Jensen","sequence":"additional","affiliation":[{"name":"Department of Family Medicine, Mayo Clinic, Rochester, MN, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1970-1344","authenticated-orcid":false,"given":"Jennifer","family":"Pecina","sequence":"additional","affiliation":[{"name":"Department of Family Medicine, Mayo Clinic, Rochester, MN, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4646-1748","authenticated-orcid":false,"given":"Nathaniel E","family":"Miller","sequence":"additional","affiliation":[{"name":"Department of Family Medicine, Mayo Clinic, Rochester, MN, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6170-4592","authenticated-orcid":false,"given":"Michelle","family":"Duvall","sequence":"additional","affiliation":[{"name":"Department of Family Medicine, Mayo Clinic, Rochester, MN, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4516-379X","authenticated-orcid":false,"given":"Elissa M","family":"Nelson","sequence":"additional","affiliation":[{"name":"Enterprise Office of Access Management, Mayo Clinic, Rochester, MN, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0282-9181","authenticated-orcid":false,"given":"Matthew C","family":"Thompson","sequence":"additional","affiliation":[{"name":"Enterprise Office of Access Management, Mayo Clinic, Rochester, MN, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0317-6701","authenticated-orcid":false,"given":"Brenda J","family":"Johnson","sequence":"additional","affiliation":[{"name":"Enterprise Office of Access Management, Mayo Clinic, Rochester, MN, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2624-0649","authenticated-orcid":false,"given":"Brian A","family":"Crum","sequence":"additional","affiliation":[{"name":"Department of Neurology, Mayo Clinic, Rochester, MN, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8340-5692","authenticated-orcid":false,"given":"Robert","family":"Stroebel","sequence":"additional","affiliation":[{"name":"Department of Medicine, Division of Community Internal Medicine, Geriatrics, and Palliative Care, Mayo Clinic, Rochester, MN, USA"},{"name":"Primary Care Internal Medicine, Mayo Clinic, Rochester, MN, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2023,7,25]]},"reference":[{"key":"bibr1-23333928231186209","unstructured":"NHS 111 online, 2022.
