RESUMO
RESUMO Objetivo: Definir o perfil epidemiológico e os principais determinantes de morbimortalidade dos pacientes cirúrgicos não cardíacos de alto risco no Brasil. Métodos: Estudo prospectivo, observacional e multicêntrico. Todos os pacientes cirúrgicos não cardíacos admitidos nas unidades de terapia intensiva, ou seja, considerados de alto risco, no período de 1 mês, foram avaliados e acompanhados diariamente por, no máximo, 7 dias na unidade de terapia intensiva, para determinação de complicações. As taxas de mortalidade em 28 dias de pós-operatório, na unidade de terapia intensiva e hospitalar foram avaliadas. Resultados: Participaram 29 unidades de terapia intensiva onde foram realizadas cirurgias em 25.500 pacientes, dos quais 904 (3,5%) de alto risco (intervalo de confiança de 95% - IC95% 3,3% - 3,8%), tendo sido incluídos no estudo. Dos pacientes envolvidos, 48,3% eram de unidades de terapia intensiva privadas e 51,7% de públicas. O tempo de internação na unidade de terapia intensiva foi de 2,0 (1,0 - 4,0) dias e hospitalar de 9,5 (5,4 - 18,6) dias. As taxas de complicações foram 29,9% (IC95% 26,4 - 33,7) e mortalidade em 28 dias pós-cirurgia 9,6% (IC95% 7,4 - 12,1). Os fatores independentes de risco para complicações foram Simplified Acute Physiology Score 3 (SAPS 3; razão de chance − RC = 1,02; IC95% 1,01 - 1,03) e Sequential Organ Failure Assessment Score (SOFA) da admissão na unidade de terapia intensiva (RC =1,17; IC95% 1,09 - 1,25), tempo de cirurgia (RC = 1,001; IC95% 1,000 - 1,002) e cirurgias de emergências (RC = 1,93; IC95% 1,10 - 3,38). Em adição, foram associados com mortalidade em 28 dias idade (RC = 1,032; IC95% 1,011 - 1,052) SAPS 3 (RC = 1,041; IC95% 1,107 - 1,279), SOFA (RC = 1,175; IC95% 1,069 - 1,292) e cirurgias emergenciais (RC = 2,509; IC95% 1,040 - 6,051). Conclusão: Pacientes com escores prognósticos mais elevados, idosos, tempo cirúrgico e cirurgias emergenciais estiveram fortemente associados a maior mortalidade em 28 dias e mais complicações durante permanência em unidade de terapia intensiva.
ABSTRACT Objective: To define the epidemiological profile and the main determinants of morbidity and mortality in noncardiac high surgical risk patients in Brazil. Methods: This was a prospective, observational and multicenter study. All noncardiac surgical patients admitted to intensive care units, i.e., those considered high risk, within a 1-month period were evaluated and monitored daily for a maximum of 7 days in the intensive care unit to determine complications. The 28-day postoperative, intensive care unit and hospital mortality rates were evaluated. Results: Twenty-nine intensive care units participated in the study. Surgeries were performed in 25,500 patients, of whom 904 (3.5%) were high-risk (95% confidence interval - 95%CI 3.3% - 3.8%) and were included in the study. Of the participating patients, 48.3% were from private intensive care units, and 51.7% were from public intensive care units. The length of stay in the intensive care unit was 2.0 (1.0 - 4.0) days, and the length of hospital stay was 9.5 (5.4 - 18.6) days. The complication rate was 29.9% (95%CI 26.4 - 33.7), and the 28-day postoperative mortality rate was 9.6% (95%CI 7.4 - 12.1). The independent risk factors for complications were the Simplified Acute Physiology Score 3 (SAPS 3; odds ratio - OR = 1.02; 95%CI 1.01 - 1.03) and Sequential Organ Failure Assessment Score (SOFA) on admission to the intensive care unit (OR = 1.17; 95%CI 1.09 - 1.25), surgical time (OR = 1.001, 95%CI 1.000 - 1.002) and emergency surgeries (OR = 1.93, 95%CI, 1.10 - 3.38). In addition, there were associations with 28-day mortality (OR = 1.032; 95%CI 1.011 - 1.052), SAPS 3 (OR = 1.041; 95%CI 1.107 - 1.279), SOFA (OR = 1.175, 95%CI 1.069 - 1.292) and emergency surgeries (OR = 2.509; 95%CI 1.040 - 6.051). Conclusion: Higher prognostic scores, elderly patients, longer surgical times and emergency surgeries were strongly associated with higher 28-day mortality and more complications during the intensive care unit stay.

OBJECTIVES: Acute kidney injury is associated with many conditions, and no interventions to improve the outcomes of established acute kidney injury have been developed. We performed this study to determine whether goal-directed therapy conducted during the early stages of acute kidney injury could change the course of the disease. METHODS: This was a multicenter prospective randomized controlled study. Patients with early acute kidney injury in the critical care unit were randomly allocated to a standard care (control) group or a goal-directed therapy group with 8h of intensive treatment to maximize oxygen delivery, and all patients were evaluated during a period of 72h. ClinicalTrials.gov: NCT02414906. RESULTS: A total of 143 patients were eligible for the study, and 99 patients were randomized. Central venous oxygen saturation was significantly increased and the serum lactate level significantly was decreased from baseline levels in the goal-directed therapy group (p=0.001) compared to the control group (p=0.572). No significant differences in the change in serum creatinine level (p=0.96), persistence of acute kidney injury beyond 72h (p=0.064) or the need for renal replacement therapy (p=0.82) were observed between the two groups. In-hospital mortality was significantly lower in the goal-directed therapy group than in the control group (33% vs. 51%; RR: 0.61, 95% CI: 0.37-1.00, p=0.048, number needed to treat=5). CONCLUSIONS: Goal-directed therapy for patients in the early stages of acute kidney injury did not change the disease course.

Objetivo: Avaliar as causas e os fatores associados a mortes de pacientes na enfermaria que receberam alta de unidades de terapia intensiva. Métodos: Estudo piloto, retrospectivo, observacional, de coorte. Foram avaliados os registros de todos os pacientes admitidos no período de 1º de fevereiro de 2013 a 30 de abril de 2013 em duas unidades de um hospital universitário público/privado. Dados demográficos, clínicos, escores de risco e desfechos foram retirados do Sistema de Monitorização Epimed e confirmados no sistema de registro eletrônico do hospital. Foram calculados o risco relativo e seus respectivos intervalos de confiança. Resultados: Um total de 581 pacientes foi avaliado. A taxa de mortalidade na unidade de terapia intensiva foi 20,8% e, no hospital, de 24,9%. A principal causa de óbito foi choque séptico em 58,3% dos que faleceram após a alta da unidade de terapia intensiva. Dos pacientes do sistema público de saúde, 73 (77,6%) morreram na unidade de terapia intensiva e 21 (22,4%) morreram no hospital, após a alta da unidade. Dos pacientes do Sistema Suplementar de Saúde, 48 (94,1%) morreram na unidade de terapia intensiva e 3 (5,9%) morreram no hospital, após a alta da unidade (risco relativo de 3,87; intervalo de confiança de 95% de 1,21 - 12,36; p < 0,05). A taxa de mortalidade pós-alta foi significativamente maior em pacientes com tempo de internação em unidade de terapia intensiva superior a 6 dias. Conclusão: A principal causa de morte de pacientes que receberam alta da unidade de terapia intensiva e morreram na enfermaria antes da alta hospitalar foi o choque séptico. A cobertura pelo sistema público de saúde e o maior tempo de internação na unidade de terapia intensiva foram fatores associados à morte, após a alta da unidade de terapia intensiva. .
Objective: To assess the causes and factors associated with the death of patients between intensive care unit discharge and hospital discharge. Methods: The present is a pilot, retrospective, observational cohort study. The records of all patients admitted to two units of a public/private university hospital from February 1, 2013 to April 30, 2013 were assessed. Demographic and clinical data, risk scores and outcomes were obtained from the Epimed monitoring system and confirmed in the electronic record system of the hospital. The relative risk and respective confidence intervals were calculated. Results: A total of 581 patients were evaluated. The mortality rate in the intensive care unit was 20.8% and in the hospital was 24.9%. Septic shock was the cause of death in 58.3% of patients who died after being discharged from the intensive care unit. Of the patients from the public health system, 73 (77.6%) died in the intensive care unit and 21 (22.4%) died in the hospital after being discharged from the unit. Of the patients from the Supplementary Health System, 48 (94.1%) died in the intensive care unit and 3 (5.9%) died in the hospital after being discharged from the unit (relative risk, 3.87%; 95% confidence interval, 1.21 - 12.36; p < 0.05). The post-discharge mortality rate was significantly higher in patients with intensive care unit hospitalization time longer than 6 days. Conclusion: The main cause of death of patients who were discharged from the intensive care unit and died in the ward before hospital discharge was septic shock. Coverage by the public healthcare system and longer hospitalization time in the intensive care unit were factors associated with death after discharge from the intensive care unit. .
