Abstract
This study aimed to investigate the association between serum magnesium trajectory and risk of in-hospital mortality in intensive care unit (ICU) patients with sepsis. Adult sepsis patients who had complete data on serum magnesium at ICU admission (at 0, 12, 24, 36 and 48 hours after ICU admission) based the 2012-2019 Medical Information Mart for Intensive Care IV (MIMIC-IV) database were included in this retrospective cohort study. Serum magnesium trajectories were identified using K-means cluster analysis. The multivariable Cox proportional-hazards model was used to evaluate the association between magnesium level at different time points or magnesium trajectory and in-hospital mortality. A total of 2,270 patients with sepsis were enrolled, and in-hospital mortality occurred in 716 (31.54%). Three trajectories were identified: a high-level declining trajectory, normal-level stable trajectory, and low-level rising trajectory. Among the magnesium levels at different time points, a higher serum magnesium level only at ICU admission (0h) (hazard ratio [HR] = 1.13, 95% confidence interval [CI]: 1.03-1.23) was associated with an increased risk of in-hospital mortality. Compared with the normal-level stable trajectory group, patients in the low-level rising trajectory group (HR = 0.82, 95%CI: 0.70-0.97) had a reduced risk of in-hospital mortality, but no association with in-hospital mortality was found in patients in the high-level declining trajectory group (p=0.812). Conclusion: Sepsis patients with a low-level, rising magnesium trajectory may have a reduced risk of in-hospital mortality.
期刊介绍:
Magnesium Research, the official journal of the international Society for the Development of Research on Magnesium (SDRM), has been the benchmark journal on the use of magnesium in biomedicine for more than 30 years.
This quarterly publication provides regular updates on multinational and multidisciplinary research into magnesium, bringing together original experimental and clinical articles, correspondence, Letters to the Editor, comments on latest news, general features, summaries of relevant articles from other journals, and reports and statements from national and international conferences and symposiums.
Indexed in the leading medical databases, Magnesium Research is an essential journal for specialists and general practitioners, for basic and clinical researchers, for practising doctors and academics.
