Availability of data and materials {29}
Details about the study will be posted on information boards in the participating hospital. Standard operating procedures for cleaning specific items of shared medical equipment will be developed and subsequently explained at the in-service (if they are not already in existence at the hospital). These will also be readily available for staff for future reference as needed. Availability of data may be available upon reasonable request, by contacting a chief investigator and providing the appropriate ethical approvals.
