BackgroundSevere sepsis remains the most common cause of death in intensive care units (ICUs) according to many epidemiological studies. There are no data in Poland on the extent of severe sepsis cases treated in ICUs. The aim of the study was to analyse the course and outcome of severe sepsis patients treated in Polish ICUs.MethodsIn 2003, the internet-based severe sepsis registry was created as a multicentre observational research project. An online questionnaire was made accessible to ICUs participating in the study. Questionnaires were completed after the discharge of patients and included demographic data, clinical and microbiological information about the cause, course, treatment and outcome of septic patients. All data were given voluntarily and anonymously.ResultsDuring the 7-year period (2003-2009), 4999 cases of severe sepsis were registered for analysis. The mean age of septic patients was 57 years, and the majority of the patients were men (58%). The mean length of stay in the ICU was 10 days. A significant decrease in the mortality rate was observed from 54% in 2003 and 56% in 2004 to 46% in 2009 (P < 0.05). Most of the patients were admitted to the ICU for surgical reasons (56%), and intra-abdominal infections predominated (49%). Severe sepsis patients were admitted to ICUs in critical condition, and the majority of them (89%) had 3 or more organs dysfunction. The APACHE II score on admission was 26 points. Community acquired infections were the most frequent cause of severe sepsis (53%). Most of the pathogens responsible for infection were Gram-negative bacteria (58%). Gram-positive bacteria were identified in 34% of patients and fungi in 16%. A positive blood culture was detected in 41% of patients. Vasopressors were administered to most of the patients (86%). There was a marked increase in the frequency of administering noradrenaline and a decrease in administering dopamine. Renal replacement therapy was applied in 22% of the patients, and there was a marked increase in this type of therapy in the last two years of the study period.ConclusionsPatients with severe sepsis involved in the 7-year registry were critically ill in half of the cases because of intra-abdominal infections, and the majority of them had multi-organ dysfunction. The mortality of registered patients was high, but it significantly decreased during the observation time. Based on the results obtained from this voluntary registry, the authors conclude that mandated sepsis registries should be established in Polish hospitals to improve the strategy of diagnosing and managing this syndrome.
