{"doi":"10.1001/jamanetworkopen.2021.20622","title":"Association of Inpatient Continuity of Care With Complications and Length of Stay Among Hospitalized Medicare Enrollees","abstract":"Importance: Continuity in primary care is associated with improved outcomes, but less information is available on the association of continuity of care in the hospital with hospital complications. Objective: To assess whether the number of hospitalists providing care is associated with subsequent hospital complications and length of stay. Design, Setting, and Participants: This retrospective cohort study used multilevel logistic regression models to analyze Medicare claims for medical admissions from 2016 to 2018 with a length of stay longer than 4 days. Admissions with multiple charges on the same day from a hospitalist or an intensive care unit (ICU) stay during hospital days 1 to 3 were excluded. The data were accessed and analyzed from November 1, 2020, to April 30, 2021. Exposures: The number of different hospitalists who submitted charges during hospital days 1 to 3. Main Outcomes and Measures: Overall length of stay and transfer to ICU or a new diagnosis of drug toxic effects on hospital day 4 or later. Results: Among the 617 680 admissions, 362 376 (58.7%) were women, with a mean (SD) age of 80.2 (8.4) years. In 306 037 admissions (49.6%), the same hospitalist provided care on days 1 to 3, while 2 hospitalists provided care in 274 658 admissions (44.5%), and 3 hospitalists provided care in 36 985 admissions (6.0%). There was no significant association between the number of different hospitalists on days 1 to 3 and either length of stay or subsequent ICU transfers. Admissions seeing 2 or 3 hospitalists had a slightly greater adjusted odds of subsequent new diagnoses of drug toxic effects (2 hospitalists: odds ratio [OR], 1.04; 95% CI, 1.02-1.07; 3 hospitalists: OR, 1.07; 95% CI, 1.03-1.12). Conclusions and Relevance: There was little evidence that receiving care from multiple hospitalists was associated with worse outcomes for patients receiving all their general medical care from hospitalists.","journal":"JAMA Network Open","year":2021,"id":196206,"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":7,"citer_count":0,"citers_with_citation_signal":0,"citers_with_endowment":0,"datacite_reuse_total":0,"is_dataset":false,"is_dataset_confidence":0.9112,"is_data_producer":false,"deposit_databanks":null,"is_oa":true,"file_count":0,"downloads":0,"has_version_chain":false,"published_date":"2021-01-01","fair_score":null,"fair_percentile":null,"algorithm_id":"datarank_citation_only_1hop_v6","ranking_scope":"data_only","authors":[{"id":396965,"name":"Shuang Li","orcid":"0000-0001-6661-824X","position":1,"is_corresponding":false},{"id":768272,"name":"Erin Hommel","orcid":"0000-0003-1975-4008","position":2,"is_corresponding":false},{"id":517586,"name":"Ann B.
