Applicability of the interventions recommended for patients at risk or with delirium in medical and post-acute settings: a systematic review and a Nominal Group Technique study.

Applicability should be assessed with experts in the field to understand the involved factors. One-third of interventions have been judged as applicable in the Italian context; the nurses' expertise, the work environment features, and the time required for each intervention in a high workload setting may prevent the full applicability of the interventions recommended by the literature.
