RÉSUMÉ
Introduction: Sepsis has a death rate of ?25% globally and its clinical treatment presents an important clinical challenge. The rapid progression of sepsis requires correspondingly swift adjustments in therapy, and accurate identification of disease severity is therefore vitally important for predicting prognosis, treatment, preventing complications, reducing complication and mortality. With this background, the present research is aimed to study the relation of serum procalcitonin levels in cases with sepsis, to calculate APACHE II scores and to correlate the levels of serum PCT levels with APACHE II Score with the outcome. Methodology: This was a prospective observational non interventional cohort study was conducted in the Clinic of Intensive Care unit of a tertiary care hospital and medical college in western India from May 2020 to December 2020. Results: A total of 75 patients, admitted to the ICU with the diagnosis of sepsis, were included in this prospective observational study. Of them 47 (62.7%) were males and highest cases were aged between 60 to 69 years. Of the total 75 patients, 47 (62.7%) patients were survivors. Age, gender and involvement of system were not associated with mortality while lower APACHE II score and presence of co-morbidities were significantly associated with mortality. Conclusion: From this study we conclude that the lower APCHE II score and presence of co-morbidity significantly increases the mortality in ICU patients admitted with sepsis
