Practice and perception–a nationwide survey of therapy habits in sepsis
SepNet - German Competence Network Sepsis

Abstract (Expand)

OBJECTIVE To simultaneously determine perceived vs. practiced adherence to recommended interventions for the treatment of severe sepsis or septic shock. DESIGN One-day cross-sectional survey. SETTING …TING Representative sample of German intensive care units stratified by hospital size. PATIENTS Adult patients with severe sepsis or septic shock. INTERVENTIONS None. MEASUREMENTS AND MAIN RESULTS Practice recommendations were selected by German Sepsis Competence Network (SepNet) investigators. External intensivists visited intensive care units randomly chosen and asked the responsible intensive care unit director how often these recommendations were used. Responses \textquotedblalways\textquotedbl and \textquotedblfrequently\textquotedbl were combined to depict perceived adherence. Thereafter patient files were audited. Three hundred sixty-six patients on 214 intensive care units fulfilled the criteria and received full support. One hundred fifty-two patients had acute lung injury or acute respiratory distress syndrome. Low-tidal volume ventilation \textless or = 6 mL/kg/predicted body weight was documented in 2.6% of these patients. A total of 17.1% patients had tidal volume between 6 and 8 mL/kg predicted body weight and 80.3% \textgreater 8 mL/kg predicted body weight. Mean tidal volume was 10.0 +/- 2.4 mL/kg predicted body weight. Perceived adherence to low-tidal volume ventilation was 79.9%. Euglycemia (4.4-6.1 mmol/L) was documented in 6.2% of 355 patients. A total of 33.8% of patients had blood glucose levels \textless or = 8.3 mmol/L and 66.2% were hyperglycemic (blood glucose \textgreater 8.3 mmol/L). Among 207 patients receiving insulin therapy, 1.9% were euglycemic, 20.8% had blood glucose levels \textless or = 8.3 mmol/L, and 1.0% were hypoglycemic. Overall, mean maximal glucose level was 10.0 +/- 3.6 mmol/L. Perceived adherence to strict glycemic control was 65.9%. Although perceived adherence to recommendations was higher in academic and larger hospitals, actual practice was not significantly influenced by hospital size or university affiliation. CONCLUSIONS This representative survey shows that current therapy of severe sepsis in German intensive care units complies poorly with practice recommendations. Intensive care unit directors perceive adherence to be higher than it actually is. Implementation strategies involving all intensive care unit staff are needed to overcome this gap between current evidence-based knowledge, practice, and perception.

Acute renal failure in patients with severe sepsis and septic shock–a significant independent risk factor for mortality: results from the German Prevalence Study
SepNet - German Competence Network Sepsis

Abstract (Expand)

BACKGROUND Sound data about the prevalence of acute renal failure (ARF) among patients with severe sepsis and septic shock are lacking. Further, it is not known whether ARF is an independent risk factor …r for mortality in septic patients or merely an indicator of disease severity. METHODS A prospective cross-sectional one-day prevalence study was carried out in a representative sample of German ICUs, divided into five strata (\textless 200 beds; 201-400 beds; 401-600 beds; \textgreater 600 beds; university hospitals). 3877 patients were screened of whom 415 had severe sepsis and septic shock. RESULTS Fourteen patients (3.4%) had chronic dialysis-dependent RF and were excluded from analysis. Of the remaining 401 patients, 166 (41.4%) had ARF, as defined by a rise in creatinine above twice the upper limit of normal and/or a drop in urine output to \textless 0.5 ml/kg bodyweight. Median APACHE II score was 22 in patients with ARF and 16 in patients without ARF (p\textless 0.0001). Patients with severe sepsis/septic shock had an overall hospital mortality of 55.2%. Hospital mortality in patients with ARF was 67.3% and without ARF 42.8% (p\textless 0.0001). After adjustment for APACHE II score and age, ARF remained a significant independent risk factor for death [odds ratio (OR) 2.11, 95% confidence interval (CI) 1.27-3.52]. Mortality in septic patients was not associated with pre-existing, non-dialysis-dependent chronic kidney disease, whereas in dialysis-dependent patients with sepsis mortality increased to 86%. CONCLUSION In this representative survey in patients with severe sepsis/septic shock, prevalence of ARF is high with 41.4%. ARF represents a significant independent risk factor for mortality in these patients.

Epidemiology of sepsis in Germany: results from a national prospective multicenter study
SepNet - German Competence Network Sepsis

Abstract (Expand)

OBJECTIVE To determine the prevalence and mortality of ICU patients with severe sepsis in Germany, with consideration of hospital size. DESIGN Prospective, observational, cross-sectional 1-day …day point-prevalence study. SETTING 454 ICUs from a representative nationwide sample of 310 hospitals stratified by size. Data were collected via 1-day on-site audits by trained external study physicians. Visits were randomly distributed over 1 year (2003). PATIENTS Inflammatory response of all ICU patients was assessed using the ACCP/SCCM consensus conference criteria. Patients with severe sepsis were followed up after 3 months for hospital mortality and length of ICU stay. MEASUREMENTS AND RESULTS Main outcome measures were prevalence and mortality. A total of 3,877 patients were screened. Prevalence was 12.4% (95% CI, 10.9-13.8%) for sepsis and 11.0% (95% CI, 9.7-12.2%) for severe sepsis including septic shock. The ICU and hospital mortality of patients with severe sepsis was 48.4 and 55.2%, respectively, without significant differences between hospital size. Prevalence and mean length of ICU stay of patients with severe sepsis were significantly higher in larger hospitals and universities (\textless/= 200 beds: 6% and 11.5 days, universities: 19% and 19.2 days, respectively). CONCLUSIONS The expected number of newly diagnosed cases with severe sepsis in Germany amounts to 76-110 per 100,000 adult inhabitants. To allow better comparison between countries, future epidemiological studies should use standardized study methodologies with respect to sepsis definitions, hospital size, and daily and monthly variability.
