Abstract: OBJECTIVE: To determine outcome and natural course of systemic inflammatory response syndrome (SIRS) stages in adult febrile neutropenic patients. DESIGN AND SETTING: Retrospective cohort study in the medicine department and intensive care unit of a university hospital. PATIENT: Adults with cancer-related neutropenia and community-acquired fever. MEASUREMENTS AND RESULTS: Patients were classified on admission according to SIRS parameters, tumor type, and degree of neutropenia. Records of clinical and laboratory data during hospitalization were reviewed. Univariate and logistic regression analyses were performed. Seventy-nine events in 62 patients were analyzed. Overall mortality rate was 20.2% (16/79). Mortality increased as SIRS stage worsened on admission. No patients with stage 2 SIRS died (neutropenia and fever alone) but 11.1% of patients with SIRS 3, 43.4% with SIRS 4, 66.6% with sepsis induced hypotension, and 90% with septic shock. SIRS stage on admission was an independent predictor of death and was related directly to rate of progression to shock, i.e., none of the patients with SIRS 2, 2.7%(1/36) of those with SIRS 3, and 30.4% (7/23) of those admitted with SIRS 4. CONCLUSIONS: Mortality and progression to septic shock increased as more SIRS criteria were met on admission. SIRS stages could serve as a risk-assessing model in febrile neutropenic patients.
