ABSTRACT Background: Post-intensive care syndrome (PICS) refers to physical, cognitive and psychological symptoms that occur after a patient is discharged from the intensive care unit (ICU). Aims: The present study aimed to explore the prevalence of PICS among ICU survivors of a tertiary care setup in Eastern India. Methods: A single-centre prospective cohort study was conducted amongst patients admitted to the ICU. A predefined, structured interview in 1st month, 3rd month, 6th month after ICU admission was done. Baseline characteristics were noted. Physical and cognitive impairment, psychological distress and general health were assessed using the Barthel Index (BI), mini-mental state examination (MMSE) tool, Hospital Anxiety and Depression Scale (HADS) and EuroQoL Visual Analogue Scale. Results: Of the 150 patients included in the study, the mean Acute Physiology and Chronic Health Evaluation II score was 20.87. The leading cause of ICU admission was sepsis (40.7%), followed by acute exacerbation of chronic obstructive pulmonary disease and pneumonia (14%). The median stay in the ICU was 8 days. Mean BI significantly decreased from 79.20 at baseline to 60.17 and 64.33 in the 3rd and 6th months, respectively. The mean HADS-Depression score increased from 3.79 at baseline to 7.08 at 3rd and 5.92 at 6th month. Similarly, the mean HADS-Anxiety score increased from 4.37 at baseline to 7.44 at 3rd and 6.31 at 6th month. The mean MMSE score decreased from 24.61 at baseline to 22.26 at the 3rd and 6th months, respectively. Thus, PICS was recorded in 90% of cases in the 3rd month and 89.3% in the 6th month. Conclusion: The management of PICS involves a multidisciplinary approach, including physical rehabilitation, cognitive rehabilitation and psychological support.
