This study aims to identify and quantify the predictors of intraoperative transesophageal echocardiography (TEE) use in cardiac valve or isolated coronary artery bypass graft (CABG) surgery. The results show that the hospital where the surgery occurs and TEE staffing are important factors influencing the use of TEE.
Objectives: To identify and quantify the predictors of intraoperative transesophageal echocardiography (TEE) use among the patients undergo-ing cardiac valve or isolated coronary artery bypass graft (CABG) surgery. Design: An observational cohort study. Setting: This study used the Centers for Medicare and Medicaid Services administrative claims dataset of the beneficiaries undergoing valve or isolated CABG surgery between 2013 to 2015. Participants: Adults aged >= 65 years of age undergoing cardiac valve or isolated CABG surgery. Interventions: Generalized linear mixed-model (GLMM) analyses were used to examine the relationship between the TEE and patient character-istics, hospital factors, and staffing differences, while accounting for clustering within hospitals. The proportion of variation in TEE use attribut-able to patient-level characteristics was quantified using odds ratios. Hospital-level factors and staffing differences were quantified using the median odds ratios (MOR) and interval odds ratios (IOR). Measurements and Main Results: Among 261,860 patients (123,702 valve procedures and 138,158 isolated CABG), the GLMM analysis dem-onstrated that the strongest predictor for intraoperative TEE use was the hospital where the surgery occurred (MOR for TEE of 2.57 in valve and 4.16 in isolated CABG). The TEE staffing variable reduced the previously unexplained across-hospital variability by 9% in valve and 21% in iso-lated CABG, and hospitals with anesthesiologist TEE staffing (versus mixed) were more likely to use TEE in both valve and CABG (MOR for TEE of 1.21 in valve and 1.84 in isolated CABG).
