Abstrakt:	Background: Drotrecogin alfa (activated) [DrotAA] is the only specific sepsis therapy that has been shown to reduce mortality. The objectives of this study were to document the profile of patients treated with DrotAA in Belgian intensive care units (ICUs), using data from a database established as part of drug reimbursement conditions in Belgium, and to compare the observed hospital mortality of these patients with their expected mortality, calculated using data from non-DrotAA-treated patients from the Belgian section of PROGRESS, a separate, voluntary, international sepsis registry collecting data from patients with severe sepsis. Material and Methods: Data from the non-DrotAA-treated patients in PROGRESS were used to calculate the expected mortality rates for DrotAA-treated patients in the Belgian registry. Using a logistic regression equation, these rates were controlled for age and the presence or absence of organ dysfunction in each of 5 organ systems. The same logistic regression technique was used to control the mortality rates observed in the DrotAA-treated patients from the Belgian registry for age and the presence or absence of each of the 5 organ dysfunctions. Adjusted expected and observed hospital mortality rates could then be compared. Results: There were 436 DrotAA patients in the Belgian registry. Almost all the patients (99.5%) had at least 2 organ failures and the hospital mortality was 51.6%. Two hundred and eighty-six of the patients had enough baseline data to be included in the regression model. Using data from the PROGRESS non-DrotAA patients, the predicted hospital mortality, controlled for age and organ dysfunction, of Belgian registry patients, had they not been treated with DrotAA, was 63.5%. The observed hospital mortality, again controlled for age and organ dysfunction, of the 286 Belgian registry patients was 50.7%, implying an adjusted absolute mortality reduction of 12.8%. Conclusions: Comparing Belgian reimbursement registry data with those of a voluntary severe sepsis register provides support for the observation that DrotAA reduces mortality rates in severe sepsis and septic shock.
