[{"arm_notes": "", "treatment_id": null, "treatment_name": "To ensure allocation concealment; the researchers will undertake randomisation through the use of an externally administered; password-protected randomisation website independently developed and maintained by the UKCRC-registered University of Exeter Clinical Trials Unit. They will pair the 18 sites according to admission case rates; hospital type and patient ethnic diversity and; for each of the nine pairs; randomly allocate one site to the intervention group and one site to the control group. Allocation will be conducted over three cycles of six sites (three pairs) each. Experimental intervention: care as usual plus the clinical protocol developed in stage 1. After each wave of implementation and drawing on process evaluation findings; the researchers will modify their clinical protocol accordingly and embed the new version of the protocol in each subsequent experimental intervention cycle site. They will embed the protocol in intervention sites before each cycle via staff education; reminders and leadership-directed strategies successfully used in a previous cluster randomised controlled trial to significantly increase handwashing by nurses and care staff. They will monitor protocol adherence and fidelity as part of the process evaluation; amending their educational and leadership strategies accordingly before each subsequent rapid cycle wave. Control: care as usual only The intervention duration will be a minimum of 72 hours. Follow up will be also after a minimum of 72 hours; ensuring that patient-participants are able to report their experience of being nursed using the nursing protocol for a minimum of 72 hours.", "treatment_type": "TODO", "pharmacological_treatment": "TODO"}]
