Incidence of Intensive Care Unit Delirium After Heart Surgery: A Feasibility Study of a Forest Environment Intervention

Background

Postoperative delirium is a serious complication in intensive care units (ICUs), particularly following cardiac surgery. It is associated with circadian rhythm disruption, sleep disturbances and adverse outcomes. ICU environments often lack natural time cues, which may exacerbate circadian misalignment and increase delirium risk.
