This study is a cluster randomized trial (CRT) where the hospitals are the clusters. 44 hospitals in Germany have confirmed their participation. Hospitals are randomized into two groups: a control and an interventional group. The control group receives conventional CMEs. The interventional group receives tools for increasing awareness such as posters and brochures. Quality measure such as benchmarking and feedback of quality indicators are used. Depending on the improvement process tools such as SWOT analyses and resistance radar will be implemented.
The CRT was preceded by a 5 months observational study (Dec. 2010 - April 2011). In about 1000 patients, participating hospitals documented their patients with severe sepsis or septic shock into a register. These data are used for final sample size calculation of the CRT and for stratification of the randomization.
The groups switch after completion of the CRT and observation continues. Thus, centers of the control group now receive the change management while the former intervention group is now without external support and is assessed for sustainability of the intervention. This study phase is planned for Nov. 2013 until March 2015. Sample size will be calculated when the CRT has been finished.
