The study will be done after obtaining approval from IEC and CTRI clearance. The written consent will be taken from all the patients in the language that they understand. If the patient is not able to give consent then consent shall be taken from the next kin. Our study is a prospective, longitudinal study that includes patients who are diagnosed with sepsis. Patients will be recruited from wards and ICUs admitted under the Department of General Medicine during the study period. RDW shall be noted at the time of presentation to the hospital. SOFA score of the patients will be calculated initially to diagnose sepsis. Serial RDW levels might be collected from the labs if available. The patient will be observed throughout his stay in the hospital until he recovers or expires. The outcome will be noted. Patients will be followed up for 1 month. Patients who leave against medical advice will not be included in the study. Other important data like the hospital number of the patient, history of present illness, comorbidities, habits like alcohol and smoking, laboratory parameters like LFT, RFT, electrolytes, blood culture sensitivity, urine, and pus culture sensitivity will be noted if available. Examination findings including vitals and systemic examination findings shall be noted. XRAY, ECG, duration of hospital stay, ionotropic requirement, dialysis requirement, and duration of ICU stay shall also be noted. Patient safety and confidentiality will not be compromised throughout the study.
