BackgroundThe effectiveness of telemedicine by a patient's own primary care provider (PCP) versus another available PCP is understudied.ObjectiveExamine the association between primary care visit modality with timeliness and follow-up in-person healthcare, including variation by visits with the patient's own PCP versus another PCP.Design And ParticipantsCohort study including primary care visits in a large, integrated delivery system in 2022.MeasuresOutcomes included timeliness (visit completed within 7 days of scheduling) and in-person follow-up (PCP visits, emergency department (ED) visits, hospitalizations) within 7 days of the index PCP visit. Logistic regression measured the association between visit modality (in-person, video, and audio-only telemedicine) with the patient's own PCP or another PCP and outcomes, adjusting for characteristics.Key ResultsAmong 4,817,317 primary care visits, 59% were in-person, 27% audio-only, and 14% video telemedicine. Most (71.3%) were with the patient's own PCP. Telemedicine visits were timelier, with modality having a larger association for visits with patient's own PCP versus another PCP (P < 0.001). For visits with patient's own PCPs, return office visit rates were 1.2% for in-person, 5.3% for video, and 6.1% for audio-only. For another PCP, rates were 2.2% for in-person, 7.3% for video, and 8.1% for audio. Follow-up ED visits ranged from 1.4% (in-person) to 1.6% (audio-only) with own PCP, compared to 1.9% (in-person) to 2.3% (audio-only) with another PCP. Differences in return office and ED visits between in-person and telemedicine were larger for visits with another PCP compared to their own PCP (P < 0.001). Follow-up hospitalizations were rare, ranging from 0.19% (in-person with own PCP) to 0.32% (video with another PCP).ConclusionDifferences in return office and ED visits between in-person and telemedicine were larger when patients saw a less familiar PCP compared to their own PCP, reinforcing the importance of care continuity.© 2024.
