Outline the issues to consider:

ICU delirium has many types, Hyperactive, Hypoactive, Subsyndromal. Plus, It has many risk factors such as; poor sleep hygiene, over sedation, age over 65 years, mechanical ventilation and uncontrolled pain. However, in my proposal, I should focus on age ( only adult) + best practices performed by nursing staff without focusing on types and risk factors.
Plus, I should assess the practice's effectivity, whether it is up to date or not, before including it in my proposal.
