Background and Aims: The incidence of specific complications and adverse outcomes in dengue patients needing admission to intensive care units (ICU) may be quite variable in different regions of India presumably because of different strains of dengue virus or due to re infection. Methods: Patients admitted with acute febrile illness (AFI) with either positive IgM antibody or NS1 antigen for dengue were enrolled. Data were collected for 3 years (2015-2017). A total of 313 patients with acute febrile illness were admitted in the study period (2252 total ICU admissions). A total of 137 (43.76%) cases were serologically proven as dengue fever. Results: Median age (IQR) of study population was 36.0 (26.0–52.0) years. Liver (65.7%) was the main organ involved followed by acute kidney Injury (AKI) (18.6%). Dengue Shock Syndrome (DSS) was found in 18.6% of cases. Fifty-two patients died and the crude mortality was 38.0%. On multivariate analysis APACHE Score <10, thrombocytopenia, hepatic dysfunction, AKI and dengue shock syndrome (DSS) were associated with the risk of mortality. Conclusion: This study in ICU patients showed high mortality in relatively younger patients. Liver (in the form of raised Bilirubin) was the most common organ dysfunction. The need to recognise early warning signs for ICU admission is highlighted.
