{"doi":"10.1111/acem.14681","title":"Standard nurse phone triage versus tele–emergency care pilot on <scp>Veteran</scp> use of in‐person acute care: An instrumental variable analysis","abstract":"OBJECTIVES: Use of acute care telemedicine is growing, but data on quality, utilization, and cost are limited. We evaluated a Veterans Affairs (VA) tele-emergency care (tele-EC) pilot aimed at reducing reliance on out-of-network (OON) emergency department (ED) care, a growing portion of VA spending. With this service, an emergency physician virtually evaluated selected Veterans calling a nurse triage line. METHODS: Calls to the triage line occurring January-December 2021 and advised to seek care acutely within 24 h were included. We described tele-EC user characteristics, common triage complaints, and patterns in referral to and management by tele-EC. The primary outcome was acute care visits (ED, urgent care, and hospitalizations at VA and OON sites) within 7 days of the index call. Secondary outcomes included mortality, OON acute care spending, and the effect of tele-EC visit modality (phone vs. video). We used both standard regression and instrumental variable (IV) analysis, using the tele-EC physician schedule as the instrument. RESULTS: Of 7845 eligible calls, 15.5% had a tele-EC visit, with case resolution documented in 57%. Compared to standard nurse triage, tele-EC users were less likely to be Black, had more prior ED visits, and were triaged as higher acuity. Calls concerning dizziness/syncope, blood in stool, and chest pain were most likely to have a tele-EC visit. Tele-EC was associated with fewer ED visits than standard nurse triage in both regression (average marginal effect [AME] -16.8%, 95% confidence interval [CI] -19.2 to -14.4) and IV analyses (AME -17.5%, 95% CI -25.1 to -9.8), lower hospitalization rate (AME -3.1%, 95% CI -6.2 to -0.0), and lower OON spending (AME -$248, 95% CI -$458 to -$38). CONCLUSIONS: Among Veterans initially advised to seek care within 24 h, use of tele-EC compared to standard phone triage led to decreased ED visits, hospitalizations, and OON spending within 7 days.","journal":"Academic Emergency Medicine","year":2023,"id":340669,"datarank":0.0,"base_score":0.0,"endowment":0.0,"self_citation_contribution":0.0,"citation_network_contribution":0.0,"self_endowment_contribution":0.0,"citer_contribution":0.0,"corpus_percentile":null,"corpus_rank":null,"citation_count":15,"citer_count":0,"citers_with_citation_signal":0,"citers_with_endowment":0,"datacite_reuse_total":0,"is_dataset":false,"is_dataset_confidence":0.9524,"is_data_producer":false,"deposit_databanks":null,"is_oa":true,"file_count":0,"downloads":0,"has_version_chain":false,"published_date":"2023-01-01","fair_score":null,"fair_percentile":null,"algorithm_id":"datarank_citation_only_1hop_v6","ranking_scope":"data_only","authors":[{"id":1075692,"name":"Paul S.
