Description
Summary:Sepsis continues to be a critical issue in intensive care, characterized by significant morbidity and mortality. This study explores the association between Vasoactive Inotrope Score (VIS) trajectories and 28-day mortality in ICU patients with sepsis, employing VIS trajectories as a marker for assessing severity and guiding therapy. We conducted a retrospective analysis of the MIMIC-IV database, which included sepsis patients admitted to the ICU between 2008 and 2019. VIS calculations were performed bi-hourly during the first 72 hours of ICU admission. Using latent growth mixture modeling, we identified distinct VIS trajectory patterns, and multivariate Cox proportional hazards models were employed to evaluate their association with 28-day mortality. Among 6,802 sepsis patients who met the inclusion criteria, four distinct VIS trajectory patterns were identified: “Low-Decreasing” (52.1%), “Mild-Ascending” (13.2%), “Moderate-Decreasing” (23.0%), and “High-Stable” (11.6%). The 28-day survival analysis demonstrated that, compared to the “Low-Decreasing” group, the “Mild-Ascending” group had a hazard ratio (HR) for mortality of 2.55 (95% CI: 2.19–2.97, P < 0.001), the “Moderate-Decreasing” group had an HR of 1.20 (95% CI: 1.03–1.41, P = 0.021), and the “High-Stable” group presented the highest risk with an HR of 4.19 (95% CI: 3.43–5.12, P < 0.001). This study offers significant insights into the prognostic value of VIS trajectories in sepsis patients. The identification of distinct trajectory patterns not only underscores the heterogeneity in sepsis but also emphasizes the importance of personalized management strategies. The findings underscore the potential of VIS trajectory monitoring in predicting 28-day outcomes and in guiding clinical decision-making in ICU settings.
