Secondary outcomes: | |||
1. Changes in costs associated with implementing the bundle | Frequency and value of resources used in implementing the bundle (costs incurred) | Hospital specific items collated from existing hospital-based data sets and supplied to project team by trial site team for analysis.

2. Changes in QALYs associated with implementing the bundle | Opportunity cost of infection in terms of: 1. Deaths 2. QALYs | Calculated using estimates from the published literature on attributable mortality and morbidity for infection | |
