Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| incidence of postoperative delirium | 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 : 1. Acute onset and fluctuating course Determined by collateral history or repeated clinic assessment 2. Inattention Counting from 20-1 is a simple (if blunt) test for this 3. Disorganized thinking 4. Altered levels of consciousness |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| comprehensive geriatric assessment(CGA) | 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) |
| duration of delirium | 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). |
| total score of QOR-40 | 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) |
| type of delirium | 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. |
