Higher Insulin Resistance in Female ICU patients. Brussels, Belgium: e-ISICEM: International Symposium on Intensive Care and Emergency Medicine (virtual). 15/09/2020-18/09/2020.

This retrospective analysis examines potential differences in the evolution of insulin sensitivity (SI) and its variability (%ΔSI) between sexes. Significant differences would suggest differences in the metabolic stress response and glycemic response to insulin therapy, and, thus, the need for more personalized glycemic control (GC). Methods: Retrospective data from 145 ICU patients (N=8710 hours) are used to hourly identify hourly model-based SI and its rate of change %ΔSI in 6-hour blocks from ICU admission to 72 hours. The evolution of SI and %ΔSI are compared for males and females. Hypothesis testing (95% confidence interval (CI) bootstrapped difference in medians) assesses if differences are significant, and equivalence testing assesses if differences are clinically equivalent. Results: Females have significantly lower SI levels than males (p<0.05), and this difference is not clinically equivalent (Figure 1; top). Differences in %ΔSI are not significant (p>0.05), and these differences are clinically equivalent (Figure 1; bottom).enAll rights reserved unless otherwise statedConference Contributions - Published2021-04-1911 Medical and Health SciencesFields of Research::40 - Engineering::4003 - Biomedical engineering::400306 - Computational physiologyFields of Research::32 - Biomedical and clinical sciences::3202 - Clinical sciences::320212 - Intensive careFields of Research::32 - Biomedical and clinical sciences::3202 - Clinical sciences::320208 - Endocrinologyhttp://doi.org/10.1186/s13054-020-03187-9
