We compared ED visits that did and did not have a usual clinician with 3:1 propensity score matching on age, gender, race, chronic condition number (2+ vs. &lt;\u20092), and geographical area. Our primary outcome was the proportion of ACSC\u2010related Medicare beneficiary ED visits that were and were not associated with a usual clinician. Our secondary outcome was the presence of an all\u2010cause ED revisit in the 30\u2009days following the initial ED visit.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      We examined 22,484 ED visits between 2015 and 2020, representing over 86 million ED visits nationally. Among ED visits by older adults, 20,849 (92.7%) were among those with a usual clinician. The proportion of ACSC\u2010related ED visits by older adults with and without a usual clinician did not differ (14.8% vs. 14.7%, adjusted marginal difference [AMD] \u22120.20%, 95% CI: \u22122.17\u20131.78,\n                      <jats:italic>p<\/jats:italic>\n                      \u2009=\u20090.97).
