A patient arrives at the emergency department with a suspected infection. Their vital signs are slightly abnormal, but not alarming. Hours later, their condition worsens. Additional tests are ordered. Treatment is escalated. Eventually, the patient develops septic shock.
Looking back, clinicians can often identify signs that deterioration was already underway.
The challenge is recognizing those signals early enough to change the outcome.
For years, healthcare organizations have measured sepsis performance using a concept known as "time zero", the point at which a patient meets criteria for sepsis or septic shock. While this approach has helped standardize care, it focuses attention on a single moment in time.
Patients, however, do not become critically ill in a single moment.
At the University of Texas Managing and Optimizing Sepsis Treatment (UT-MOST) Collaborative, participating institutions are exploring a different perspective: sepsis is not an event. It is a trajectory.
Patients often move through stages of illness before developing sepsis or septic shock. Along the way, there are changes in clinical condition, assessments by healthcare teams, treatment decisions, and opportunities for intervention. Understanding these transitions may reveal when deterioration begins, how it is recognized, and where earlier action could improve outcomes.
To better understand these patterns, UT-MOST is studying five interconnected elements of sepsis care: early detection of deterioration, progression of illness over time, changes in patient risk, clinical response, and patient outcomes. Together, these elements provide a more complete picture of sepsis care than any single timestamp can offer.
The goal is not to replace existing quality measures, but to complement them by helping healthcare organizations understand what happens before severe deterioration occurs and where opportunities for earlier intervention may exist.
A defining strength of UT-MOST is its collaborative approach. Academic medical centers and healthcare organizations across Texas are working together to share knowledge, compare workflows, and learn from one another's experiences. By examining patterns across diverse patient populations and care settings, the collaborative seeks to identify common opportunities to improve recognition, treatment, and outcomes.
Sepsis remains one of healthcare's most time-sensitive conditions. Timely treatment will always matter. But the greatest opportunity may lie even earlier, recognizing the trajectory of deterioration before it becomes a crisis.
That is the future UT-MOST is helping to build.
