Primary | Frequency of delirium | evaluate the occurence of delirium by using Confusion Assessment Method for The Intensive Care Unit (CAM-ICU) | within the first 5 postoperative days | |
Secondary | Effectiveness of analgesia | to assess the effect of analgesia by using Numerical Rating Scale (NRS);This method is composed of 0 to 10, a total of 11 Numbers. Patients with 0 to 10 this digital describe pain intensity, the greater the number the pain degree is more serious.0 painless, 1 ~ 3 mild pain (pain does not affect sleep), 4 ~ 6 moderate pain, 7 ~ 9 severe pain (couldn't sleep), 10 severe pain. We should ask the patient pain degree, tag, or let the patient draw one of the most can represent their own pain degree of digital. | during postoperative days 1-5 | |
Secondary | Length of days in ICU and hospital stay after surgery | evaluate the length of days in ICU and hospital stay from postoperative to discharge | from day 1 after surgery to discharge (up to 24 weeks) | |
Secondary | Incidence of non-delirium complications | Incidence of non-delirium complications with 28 days after surgery | with 28 days after surgery | |
Secondary | All-cause28-day mortality | All-cause28-day mortality | day 28 after surgery | |
Secondary | life-Quality evaluation of 28-day survivors | evaluate the quality of life by using the world health organization quality of life measurement scale(WHOQOL-BREF). WHOQOL-BREF contains 26 items, summarizes the physiological, psychological, social relations, the environment in the field of four content.Consists of two independent analysis problem items: question 1 (G1) ask individual about their quality of life of the general subjective feeling, question 2 (G4) individual asked the total subjective feeling bout their own health. Domain scores are the positive (i.e., the higher the score, the better the quality of life).Field scoring through the calculation of average of their entries 4 times. and patients will be assessed via phone call if they are discharged before day 28 after surgery | day 28 after surgery | |
Secondary | Cognitive function of 28-day survivors | evaluate the cognitive function of 28-day survivors by using modified version of the telephone questionnaire for cognitive function questionnaire (TICS-m);It contains 21 items, total score 50 points, can be divided into three parts: the memory part (score 20), directional force (score 13), the capablity of language, and pay attention (score 17). TICS -m total score 50 points, scored < 28 divided into dementia, 28 and 33 were divided into mild cognitive dysfunction, =33 were divided into normal. Patients will be assessed via phone call if they are discharged before day 28 after surgery | day 28 after surgery |
