Early detection strategy and mortality reduction in severe sepsis

Area of Science:

• Critical Care Medicine
• Infectious Diseases
• Hospital Administration

Background:

• Severe sepsis and septic shock are life-threatening conditions requiring timely recognition and intervention.
• Existing guidelines, such as the Surviving Sepsis Campaign, provide a framework for treatment.
• Early detection of signs suggesting infection (SSI) is crucial for improving patient outcomes.

Purpose of the Study:

• To evaluate the effectiveness of an institutional policy aimed at improving the detection of severe sepsis and septic shock.
• To assess the impact of this policy on the time to recognition of sepsis and patient mortality.

Main Methods:

• A prospective study was conducted in a 195-bed public hospital, comparing two stages before and after policy implementation.
• Stage I involved consecutive enrollment of patients with severe sepsis/septic shock treated per guidelines.
• Stage II utilized active surveillance for signs suggesting infection (SSI) to identify patients, comparing demographic variables, time to SSI recognition (SSI-Δt), bundle compliance, and mortality.

Main Results:

• A total of 124 patients were identified (68 in Stage I, 56 in Stage II), with similar demographics.
• The time to recognition of SSI significantly decreased from 34 ± 54 hours in Stage I to 7 ± 8.4 hours in Stage II (p <0.001).
• Mortality rates at 28 days dropped from 54.4% to 30% (p <0.02), and in-hospital mortality decreased from 67.6% to 41% (p <0.003).

Conclusions:

• The implemented institutional policy successfully facilitated early identification of sepsis risk.
• This proactive approach led to a significant reduction in mortality associated with severe sepsis and septic shock.
• The findings support the adoption of active surveillance strategies for early sepsis detection in hospital settings.
