Abstract

BACKGROUND: Weekend effect characterized by worse perioperative outcomes has been demonstrated in some surgery patients admitted on weekends, as opposed to weekdays. This study aimed to examine weekend effect on open surgical repair or thoracic endovascular aneurysm repair (TEVAR) for Stanford Type B Aortic Dissection (TBAD). METHODS: Patients who underwent TBAD repair were identified in National/Nationwisde Inpatient Sample from Q4 2015-2020. Open surgery and TEVAR were examined separately. Multivariable analyses were performed comparing in-hospital perioperative outcomes of patients under weekday and weekend admission. Adjusted preoperative variables included sex, age, race, socioeconomic status, hospital characteristics, clinical symptoms, comorbidities, and elective/non-elective admission. Also, length of stay, days from admission to operation, and total hospital charge were compared. RESULTS: Among patients who underwent open TBAD repair, 1321 were admitted on weekdays and 340 on weekends. Among patients who underwent TEVAR for TBAD, 2018 were admitted on weekdays and 440 wereadmitted on weekends. There was no difference in open repair outcomes between those admitted on weekdays vs weekends. In TEVAR, weekend admission was associated with higher post-procedural kidney failure (1.14% vs .20%, aOR = 4.11, = .04) and superficial wound complications (2.73% vs 1.49%, aOR = 2.2, = .03) but lower respiratory complications (5.80% vs 3.64%, aOR = .47, = .01). Also, in TEVAR, weekend admission was associated with longer time from admission to operation (3.92 ± .27 vs 2.35 ± .09 days, < .01). CONCLUSIONS: Renal malperfusion was a common indication for TBAD repair. TBAD patients admitted over the weekend and underwent TEVAR had higher post-procedural kidney failure, which may be due to delayed diagnosis and treatment.
