However, the plurality of primary care  \n1084 Innovation in Aging, 2025, Vol. 9, No. S2  \n(PC) and specialty use among this population remains understudied. This retrospective cohort study used electronic health records from a multi-site academic health system in the Chicago metropolitan area. The cohort included older adults (≥65 years) with ≥2 chronic conditions and regular outpatient visits between 2016-2024, stratified by ADRD diagnosis. Outpatient encounters were classified into PC (internal/family medicine), ADRD specialty (geriatrics, neurology, psychiatry), or other specialty.  \nPatients were categorized based on whether their care was PC-dominant (> mean proportion of PC encounters) and whether they accessed any ADRD specialty. Among 64,279 patients, 16.2% had ADRD. Of 10,687,974 outpatient encounters, only 11.2% were PC. Overall, 18.6% of patients never accessed PC, more often among those without ADRD (21.6%) than those with (16.8%). Among patients with any PC, the average proportion of PC encounters was 16.7%±13 .3% . Patients with ADRD had less specialty-dominant care (50.0% vs. 61.1%) . Regardless of ADRD status (with ADRD vs without), patients without PC had the lowest ADRD-specialty use (55% vs 26%), while those with specialty-dominant care had the highest (78% vs 42%) .  \nSurvival was highest among patients with PC-dominant care (57% with ADRD; 81% without ADRD) . These findings highlight distinct outpatient care patterns and potential coordination gaps among PC and specialty care that need further study, which may impact outcomes among older adults with ADRD and multimorbidity.","cbCaieD40n4QwVKB","https://ap.wps.com/l/cbCaieD40n4QwVKB","pdf",1875492,"English","# Study overview\n## Cohort and setting\n## Care classification and patient grouping\n## Key utilization results\n## Survival and implications","[{\"question\":\"What outpatient care types were compared in the study?\",\"answer\":\"Outpatient encounters were classified into primary care (internal/family medicine), ADRD specialty care (geriatrics, neurology, psychiatry), or other specialty.\"},{\"question\":\"How common was ADRD in the cohort and how much care was primary care?\",\"answer\":\"Among 64,279 patients, 16.2% had ADRD.
