A Study on the Incidence and Impact of Dysglycemia in Non-diabetic Sepsis Patients

Context Dysglycemia is common in severe sepsis and is associated with a poor prognosis. There is a limited amount of research on stress-induced dysglycemia in non-diabetic sepsis patients. Aim This study aims to estimate the incidence of dysglycemia among non-diabetic patients presenting with sepsis at the Emergency Department and to determine its correlation with gender, age, APACHE II (Acute Physiology and Chronic Health Evaluation) scores, diagnosis, and duration of hospital stay. Materials and methods The study was conducted at a medical college hospital in Kochi from January 1, 2023, to December 31, 2023. A minimum sample size of 77 was derived after a pilot study, with a 95% confidence interval and 10% allowable error. A total of 100 non-diabetic sepsis patients meeting the inclusion and exclusion criteria were analyzed with regard to gender, age, diagnosis, glycemic status (hypo/hyper/normoglycemic), APACHE II scores, and hospital stay duration. Statistical analysis was performed using IBM SPSS Statistics for Windows, Version 20 (Released 2011; IBM Corp., Armonk, New York) software. Categorical variables were expressed as frequency and percentage. Continuous variables were presented as mean +/- SD (standard deviation) and median (Q1-Q3). To test the statistical significance of the association between the presence of various factors (gender, age, diagnosis) and dysglycemia, the chi-square test was used. To test the statistical significance of the difference in the mean age and APACHE II score values with dysglycemia, an independent sample t-test was used. To test the statistical significance of the difference in the median hospital stay with dysglycemia, the Whitney U test was used. Data were represented as mean +/- SD, and a p-value of <0.05 was considered to be statistically significant. Results The incidence of dysglycemia in the inclusion group was 49% (hypoglycemia in 16% and hyperglycemia in 33% of cases), and it increased with age (p=0.002). The majority of the dysglycemic patients fell into the age group >40 years. Dysglycemia was 54.8% in pneumonia and 66.7% in gastrointestinal sepsis ( p=0.138). Dysglycemia increased with an increase in APACHE II scores (p=0.017). The median hospital stay was almost the same in both normoglycemics and dysglycemics. Conclusion Dysglycemia is a frequent complication in non-diabetic patients with sepsis. It increased with age and APACHE II score, but it does not prolong the duration of hospital stay, nor is it associated with the diagnosis.
