Differences in Mortality and Sepsis-Associated Organ Dysfunction between Surgical and Non-Surgical Sepsis Patients

Abstract

(1) Background: Patients with sepsis following surgical intervention may exhibit fundamental distinctions from those experiencing sepsis without prior surgery. Despite the potential clinical importance of distinguishing these two sepsis subpopulations, dissimilarities, particularly in outcome, between surgical and non-surgical patients have been subject to limited scientific investigations in the existing literature. This study aimed to investigate the differences in mortality and sepsis-associated organ dysfunction between these two groups. (2) Methods: A retrospective analysis was conducted using data from a large cohort of prospectively enrolled patients with sepsis (n = 737) admitted to three intensive care units at University Medical Center Goettingen; patients were categorized into surgical (n = 582) and non-surgical sepsis groups (n = 155). The primary outcomes assessed were 28- and 90-day mortality rates, and secondary endpoints were multiple clinical parameters and measures of sepsis-associated organ dysfunction. (3) Results: Non-surgical patients presented a significantly higher 90-day mortality (37%) compared to surgical sepsis patients (30%, p = 0.0457). Moreover, the non-surgical sepsis group exhibited increased sepsis-associated organ dysfunction, as evidenced by higher average SOFA scores (p < 0.001), elevated levels of serum Procalcitonin (p = 0.0102), and a higher utilization of organ replacement therapies such as ventilation (p < 0.001), vasopressor treatment (p < 0.001), and renal replacement therapy (p = 0.0364). Additionally, non-surgical sepsis patients had higher organ-specific SOFA respiratory (p < 0.001), cardiovascular (p < 0.001), renal (p < 0.001), coagulation (0.0335), and central nervous system (p = 0.0206) subscores. (4) Conclusions: These results suggested that patients with non-surgical sepsis may face distinct challenges and a higher risk of adverse outcomes compared to patients with sepsis following surgical intervention. These findings have important implications for clinical decision-making, patient management, and resource allocation in sepsis care.

Decrease in Mortality after the Implementation of a Hospital Model to Improve Performance in Sepsis Care: Princess Sepsis Code

“…It is especially relevant to investigate the differences and factors related to mortality depending on the focus, as it can help us to understand different phenotypes, in view of an increasingly individualized case management, which has significance as a new line of future research for the PSC group to look for the differences in mortality between surgical and non-surgical patients, along with variables related to outcomes in surgical patients [36][37][38].…”
