{"doi":"10.1053/j.jvca.2025.08.013","title":"Practice Pattern Variability in the Use of Pulmonary Arterial Catheters in Cardiac Surgery","abstract":"OBJECTIVES: To quantify intraoperative pulmonary arterial catheter (PAC) use during cardiac surgery and identify hospital-, anesthesiologist-, and patient-level factors associated with PAC utilization. DESIGN: A cross-sectional, observational study using generalized logistic mixed models to examine variations in PAC use. SETTING: Fifty-three US academic hospitals participating in the Multicenter Perioperative Outcomes Group (MPOG) national registry PARTICIPANTS: 145,343 adult patients undergoing cardiac surgery between January 1, 2016, and December 31, 2022. INTERVENTION(S): Receipt of intraoperative PAC, defined by ≥60 minutes of physiologically plausible pulmonary arterial pressures. MEASUREMENTS & MAIN RESULTS: The primary outcome was PAC utilization. Mixed-effects logistic regression quantified fixed-effect predictors, and variation attributable to anesthesiologists and then to anesthesiologists nested within a hospital was characterized using median odds ratio (MOR). Of the 145,343 cardiac surgeries performed across 53 hospitals, 104,626 (72%) included PAC monitoring. PAC use varied widely across hospitals (0-98%) and across anesthesiologists (0-100%). PAC was used most frequently in heart transplants (94%) and lung transplants (87%) and least frequently in pulmonic valve procedures (30%). A patient's likelihood of receiving a PAC was influenced most strongly by hospital (MOR, 15.00; 95% confidence interval [CI], 8.98-28.32), with substantially less variation attributable to an anesthesiologist within the same hospital (MOR, 1.70; 95% CI, 1.61-1.81). CONCLUSIONS: Intraoperative PAC monitoring is used in nearly three-quarters of cardiac surgeries at US academic centers, with hospital practice pattern the factor most closely associated with PAC utilization.","journal":"Journal of Cardiothoracic and Vascular Anesthesia","year":2025,"id":526542,"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":3,"citer_count":0,"citers_with_citation_signal":0,"citers_with_endowment":0,"datacite_reuse_total":0,"is_dataset":false,"is_dataset_confidence":0.9294,"is_data_producer":false,"deposit_databanks":null,"is_oa":true,"file_count":0,"downloads":0,"has_version_chain":false,"published_date":"2025-01-01","fair_score":null,"fair_percentile":null,"algorithm_id":"datarank_citation_only_1hop_v6","ranking_scope":"data_only","authors":[{"id":669422,"name":"Bo Zhang","orcid":"0000-0002-4381-1124","position":1,"is_corresponding":false},{"id":1402653,"name":"Joseph M.
