Treatment and study plan

Primary outcomes

  1. incidence of postoperative delirium

    Time frame: from postoperative day 0 to postoperative day 7

    At least two times a day during the hospitalization period. Patients diagnosed with delirium using the CAM were evaluated for the duration, symptoms, and type of delirium (e.g., reduced awareness of the environment; poor cognitive skills; behavioral changes; and emotional disturbances).

    ** Confusion assessment methods(CAM) diagnostic algorism (positive or negative result, positive means delirium)

    CAM is considered positive if features 1 and 2 are present, with at least one of features 3 or 4. Below are the four criteria of features :

    • Acute onset and fluctuating course Determined by collateral history or repeated clinic assessment
    • Inattention Counting from 20-1 is a simple (if blunt) test for this
    • Disorganized thinking
    • Altered levels of consciousness

Secondary outcomes

  1. comprehensive geriatric assessment(CGA)

    Time frame: Participants will be followed for the duration of their hospital stay and until their visit within one month after discharge, with an expected average of 4 weeks

    Core component of CGA are as follows :

    The Korean version of the fatigue, resistance, ambulation, illnesses, and loss of weight (K-FRAIL) scale : 0(healthy)~8(frail) Mini Nutritional Assessment(MNA) : 0 (malnutrition)~14(normal) Geriatric Depression Scale(GDS) : 0(normal)~ 15(depression) Instrumental Activities of Daily Living(IADL)-Lawton-Brody Scale : 0~8(complete independence)

  2. duration of delirium

    Time frame: Participants will be followed for the duration of their hospital stay and until their visit within one month after discharge, with an expected average of 4 weeks

    Duration of Delirium: The duration of delirium is measured from the onset to the resolution of symptoms, recorded in hours or days (e.g., 1 day, 3 days, 5 days).

  3. total score of QOR-40

    Time frame: Participants will be followed for the duration of their hospital stay and until their visit within one month after discharge, with an expected average of 4 weeks

    The Quality of Recovery-40 (QoR-40) 40~200(better recovery)

  4. type of delirium

    Time frame: Participants will be followed for the duration of their hospital stay and until their visit within one month after discharge, with an expected average of 4 weeks

    Type of Delirium: Delirium is classified into three types: hyperactive, hypoactive, and mixed.
