Feasibility Study on Implementing Consultation-based High-quality Palliative Care Services in Intensive Care Units

Critically ill patients in intensive care units (ICUs) receive life-sustaining treatments aimed at restoring or maintaining organ function. ICU admission often involves substantial physical and existential pressures that can burden patients, their families, and surrogates. Multidisciplinary palliative care support can help alleviate potential causes of suffering. Twenty patients admitted to the ICUs at Seoul National University Hospital, diagnosed with sudden and severe acute brain injury or progressive organ failure, along with their surrogates, will be enrolled in the study. This study aims to assess the feasibility of applying consultation-based palliative care services to provide higher quality palliative care for critically ill patients with acute illnesses and their families facing poor prognoses upon ICU admission. Additionally, the study seeks to determine whether providing such palliative care services can help better respect the patient's values and goals, reduce communication conflicts, alleviate family caregivers' anxiety and depression, and enhance satisfaction with critical care.
