Community-acquired Septic Shock: Early Management and Outcome in a Nationwide Study in Finland

Aim: To determine how the early treatment guidelines were adopted, and what was the impact of early treatment on mortality in septic shock in Finland.

Methods: This study was a sub-analysis of a prospective observational investigation of severe sepsis and septic shock in Finland (Finnsepsis). All patients with severe sepsis over 4 months in 24 intensive care units were included in the Finnsepsis study. Patients with community-acquired septic shock, admitted directly from the emergency department to the intensive care unit, were included in the sub-study. The following treatment targets were evaluated: measurement of lactate during the first 6 h; analysis of blood culture before antibiotics; commencement of antibiotics within 3 h; attainment of a mean arterial pressure of > or =65 mmHg, central venous pressure of > or =8 mmHg and central venous oxygen saturation of > or =70% or mixed venous oxygen saturation of > or =65% during the first 6 h.

Results: Of the 92 patients who fulfilled the inclusion criteria, six reached all treatment targets and 33 reached four or more targets (group > or =4). The hospital mortality of group > or =4 was 24% (8/33), compared with 42% (25/59) for those who reached three or fewer targets (group < or =3) (P= 0.08). The 1-year mortality rates of group > or =4 and group < or =3 were 36% and 59% (P= 0.04), respectively. In logistic regression analysis, a delayed initiation of antimicrobials was associated with an unfavourable outcome (P= 0.04).

Conclusions: Compliance with international guidelines for the early treatment of septic shock was poor in Finnish hospitals. A failure to diagnose early and to start appropriate treatment was reflected in the high mortality. The delayed start of antibiotics was the most important individual variable leading to a high mortality in this nationwide study.
