          Abstract

          OBJETIVO: Avaliar o impacto da aplicação de uma política institucional para detecção da sepse grave ou choque séptico. MÉTODOS: Estudo antes (fase I)/depois (fase II) com coleta prospectiva de dados em hospital público de 195 leitos. Fase I: Pacientes com sepse grave ou choque séptico foram incluídos consecutivamente durante 15 meses e tratados conforme diretrizes da Campanha Sobrevivendo à Sepse. Fase II: Nos 10 meses subseqüentes, pacientes com sepse grave ou choque séptico foram arrolados a partir da busca ativa de sinais sugestivos de infecção nos pacientes internados. As duas fases foram comparadas entre si no que diz respeito às variáveis demográficas, tempo necessário para reconhecimento de pelo menos dois sinais sugestivos de infecção (Δt-SSI), aderência aos pacotes de 6 e 24 horas, e mortalidade. RESULTADOS: Foram identificados 124 pacientes com sepse grave ou choque séptico, 68 na fase I e 56 na fase II. As variáveis demográficas foram semelhantes nas fases. O Δt-SSI foi de 34 ± 54 horas na fase I e 7 ± 8,4 horas na fase II (p < 0,001). Não houve diferença na aderência aos pacotes de tratamento. Paralelamente, observou-se redução significativa das taxas de mortalidade ao 28º dia (54,4% na fase I versus 30% na fase II; p < 0,02) e hospitalar (67,6% na fase I versus 41% na fase II; p < 0,003). CONCLUSÃO: A estratégia utilizada contribuiu para a identificação antecipada do risco de sepse e resultou em diminuição da mortalidade associada à sepse grave e ao choque séptico.

          OBJECTIVE: To evaluate the impact of implementing an institutional policy for detection of severe sepsis and septic shock. METHODS: Study before (stage I), after (stage II) with prospective data collection in a 195 bed public hospital.. Stage I: Patients with severe sepsis or septic shock were included consecutively over 15 months and treated according to the Surviving Sepsis Campaign guidelines. Stage II: In the 10 subsequent months, patients with severe sepsis or septic shock were enrolled based on an active search for signs suggesting infection (SSI) in hospitalized patients. The two stages were compared for demographic variables, time needed for recognition of at least two signs suggesting infection (SSI-Δt), compliance to the bundles of 6 and 24 hours and mortality. RESULTS: We identified 124 patients with severe sepsis or septic shock, 68 in stage I and 56 in stage II. The demographic variables were similar in both stages. The Δt-SSI was 34 ± 54 hours in stage I and 7 ± 8.4 hours in stage II (p <0.001). There was no difference in compliance to the bundles. In parallel there was significant reduction of mortality rates at 28 days (54.4% versus 30%, p <0.02) and hospital (67.6% versus 41%, p <0.003). CONCLUSION: The strategy used helped to identify early risk of sepsis and resulted in decreased mortality associated with severe sepsis and septic shock.

            The influence of early hemodynamic optimization on biomarker patterns of severe sepsis and septic shock.

            Despite abundant experimental studies of biomarker patterns in early severe sepsis and septic shock, human data are few. Further, the impact of the severity of global tissue hypoxia resulting from resuscitative strategies on these early biomarker patterns remains unknown. The temporal patterns of interleukin-1 receptor antagonist, intercellular adhesion molecule-1, tumor necrosis factor-alpha, caspase-3, and interleukin-8 were serially examined over the first 72 hrs of hospitalization after early hemodynamic optimization strategies of early goal-directed vs. standard therapy for severe sepsis and septic shock patients. The relationship of these biomarker patterns to each hemodynamic optimization strategy, severity of global tissue hypoxia (reflected by lactate and central venous oxygen saturation), organ dysfunction, and mortality were examined. Abnormal biomarker levels were present upon hospital presentation and modulated to distinct patterns within 3 hrs based on the hemodynamic optimization strategy. The temporal expression of these patterns over 72 hrs was significantly associated with the severity of global tissue hypoxia, organ dysfunction, and mortality. In early severe sepsis and septic shock, within the first 3 hrs of hospital presentation, distinct biomarker patterns emerge in response to hemodynamic optimization strategies. A significant association exists between temporal biomarker patterns in the first 72 hrs, severity of global tissue hypoxia, organ dysfunction, and mortality. These findings identify global tissue hypoxia as an important contributor to the early inflammatory response and support the role of hemodynamic optimization in supplementing other established therapies during this diagnostic and therapeutic "window of opportunity."
