Weekend admissions for cardiogenic shock (CS) are associated with worse outcomes, including higher mortality and cardiac arrest rates. This situation has persisted for years and may be related to physician dissatisfaction, understaffing, or burnout.
Background: The management of cardiogenic shock (CS) requires attentiveness to details and in some cases, invasive interventions. In the past, studies have shown relationships between the day of admission and cardiovascular outcomes. We aim to analyze the trends and in-hospital outcomes of patients admitted with CS over the weekends compared to weekdays. Method: We identified all patients with CS from the National Inpatient Sample (NIS) database between 2016 and 2020. Using multivariate logistic regression analysis, baseline demographics and in-hospital outcomes were obtained and compared by weekend or weekday admission. Results: Out of 854,684 CS admissions, 199,255 (23.6%) occurred on weekends. Patients admitted over the weekend had worse outcomes, including higher rates of mortality (aOR 1.09 CI 1.05 - 1.11, p<0.001), cardiac arrest (aOR 1.09 CI 1.04 -1.14, p<0.001), and respiratory failure. We also noted higher percutaneous coronary intervention (PCI) rates (aOR 1.2 CI 1.16 - 1.25, p<0.001) but lower rates of pulmonary artery catheterization (PAC) and post-procedure pneumothorax. Weekend admissions had shorter hospital lengths of stay, and they incurred lower charges ($223,222 vs. $247,908). Between 2016 and 2020, we observed a consistent downward trend in the mortality rates of the weekend and weekday CS admissions, with consistently higher weekend than weekday admissions. Conclusion: Weekend admissions for CS are associated with worse outcomes, which have persisted for years. This now begs the question of whether physician dissatisfaction, understaffing, or burnout are responsible for this finding.
