Sepsis at Intensive Care Unit

Sepsis is a life-threatening condition caused by the body's dysregulated response to an infection. While corticosteroids are known to help stabilize blood pressure in septic shock, their ability to reduce mortality is still debated. Recent analyses suggest that combining fludrocortisone with hydrocortisone may be more effective at saving lives than hydrocortisone alone. To test this hypothesis, a large, definitive international trial is needed. However, this research proposal is for a smaller pilot study (Phase II) involving 32 critically ill patients. The primary goal of this pilot is to determine the feasibility of conducting the subsequent large-scale trial that would compare hydrocortisone alone against the combination therapy and potentially change medical practice.

This pilot feasibility randomized controlled trial (RCT) aims to determine if it feasible to recruit, deliver, and evaluate a written discharge educational material (a brochure) to adult Intensive Care Unit (ICU) patients diagnosed with sepsis. The main questions it aims to answer are: 1. Feasibility to identify and enroll \>80% of eligible participants 2. Feasibility to recruit 30 participants over a 6-month period 3. Fidelity of intervention, assessed as \>75% of participants receiving assigned intervention Researchers will assess the feasibility of comparing two groups: (1) Control - usual ICU discharge care, and (2) Intervention - usual ICU discharge care plus the receipt of an educational sepsis brochure and an explicit opportunity to ask questions about sepsis, answered by a trained intensive care unit (ICU) Registered Nurse. Participants will receive intervention or control just prior to their discharge from ICU. They will complete online or phone survey assessments 24-48 hours post ICU discharge and 15-days post hospital discharge. Mortality and readmission data will additionally be assessed at 30-days post-discharge.

Sepsis is a serious condition where the body's immune response to infection overreacts, leading to organ damage and death. Venous congestion, a buildup of blood in the veins, can occur in sepsis and contribute to organ injury. VExUS (Venous Excess Ultrasound Score) is an ultrasound method that can detect congestion early. This study examines whether ICU nurses, after training, can perform VExUS reliably, explores their experiences, and investigates links between VExUS findings and clinical outcomes.

The goal of this observational study is to learn about how transposable element levels affect the patient outcomes in sepsis. The main questions it aims to answer is: 1. Do transposable elements prematurely age the immune systems of patients with sepsis? 2. Do transposable elements correlate with increased mortality in patients with sepsis in the ICU? 3. Do transposable elements correlate with increased amount of secondary infections in patients with sepsis in the ICU? Participants will have blood drawn from them but will not be subjected to additional interventions.
