Overview
Brief Summary
This study is testing cognitive function before and after the surgery, with patient's informed consent. Patients of interest are 65 year or older, undergoing surgery in general or regional anesthesia.
Investigators are using 3 tests. These are: MMSE (Mini Mental State Exam), TEGEST test (test of gestures) and Clock drawing test.
Tests after surgery are performed 2 days until discharge. The testing is anonymous, patient is assigned a number. Main aim of this study is to find a suitable quick test of cognitive function for clinical practice before surgery in general or regional anesthesia.
Detailed Description
This study is testing cognitive function before and after the surgery, with patient's informed consent. Patients of interest are 65 year or older, undergoing surgery in general or regional anesthesia. Investigators are using 3 tests, MMSE - Mini Mental state exam, TEGEST - test of gestures and Clock drawing test with Baja scoring system. MMSE is 30-point questionnaire. Maximum score for MMSE is 30 points. Score of 25 or higher is classed as normal. If the score is below 24, the result is usually considered to be abnormal, indicating possible cognitive impairment. Score 21-23 indicate light cognitive impairment, score 20 - 11 indicate modern cognitive impairment, score 10 points or below indicate severe cognitive impairment. Maximum score for TEGEST test is 6 points. Score of 4 or less indicates possible cognitive impairments. Patient is showed 6 gestures symbolizing senses (putting on glasses, smelling the flower, looking through telescope, eating with spoon, touching the cheek and picking up the telephone). After showing patient repeats 6 gestures. Clock drawing test with Baja scoring system is a test, where patient is drawing clock with time 11:10 am. Administrator evaluates 12 digits in the clock, hour hands and pointing of the hour hands. Maximum score for Clock drawing test with Baja scoring system is 5 points. Score 4 or less indicates possible cognitive impairments. Before testing doctor is assessing Clinical frailty scale (CFS). CSF is tool that can be used to quickly and simply assess frailty. The testing takes place in anesthesiology ambulance before surgery, after operation in clinical wards. Patients can ask anytime for their results (before or after surgery). A score from 1 (very fit) to 9 (terminally ill) is given based on the descriptions and pictographs of activity and functional status. Tests after surgery are performed 2 days until discharge. The testing is anonymous a number is assigned to a patients. Patients can refuse anytime to participate in the testing. The anesthesiologist performing tests is a doctor and can't participate in patient's care in the operating room. Main aim of this study is to find a suitable quick test of cognitive function for clinical practice before surgery for patients undergoing general or regional anesthesia.

Outcomes
Primary Outcomes
Postoperative Cognitive Dysfunction - Results of MMSE Before Operation
Time Frame: 2 days before operation
MMSE test was used by administrator before surgery. MMSE is 30 point questionnaire. Maximum score is 30 points. Score of 25 or higher is classed as normal cognitive capacity, 24 points and below is indicating possible congnitive impairment, 21-23 points are light cognitive impairment, 20-11 points are modern impairment, score 10 points or below indicate severe cognitive impairment. The test took 10 minutes approximately.
Postoperative Cognitive Dysfunction - Results of MMSE After Operation
Time Frame: 3rd day after operation
MMSE test was used by administrator after surgery. MMSE is 30 point questionnaire. Score 25 or higher is know as normal cognitive capacity. Score 24 and below is indicating possible cognitive impairment, score 23-21 points are light cognitive impairment, 20-11 points are mild cognitive impairment, score 10 point or below indicate severe cognitive impairment. The test took 10 minutes approximately.
Postoperative Cognitive Dysfunction - TEGEST Test Before Operation
Time Frame: 2 days before operation
TEGEST test is used by administrator before surgery. Patient is showed 6 gestures symbolizing senses (putting on glasses, smelling the flower, looking through telescope, eating with spoon, touching the cheek, and picking up the telephone). After showing the patient repeats 6 gestures. Maximum score is 6 points, score of 4 or less indicates possible cognitive impairments. At the end of testing before surgery administrator did access if patient has possible cognitive impairment. The test took 3 minutes.
Postoperative Cognitive Dysfunction - TEGEST Test After Operation
Time Frame: 3rd day after operation
TEGEST test is used by administrator after surgery. Patient is showed 6 gestures symbolizing senses (putting on glasses, smelling the flower, looking through telescope, eating with spoon, touching the cheek, and picking up the telephone). After showing the patient repeats 6 gestures. Maximum score is 6 points, score of 4 or less indicates possible cognitive impairments. At the end of testing before surgery administrator did access if patient has possible cognitive impairment. The test took 3 minutes.
Postoperative Cognitive Dysfunction -Clock Drawing Test Before Operation
Time Frame: 2 days before operation
Clock drawing test with Baja scoring system is a test, where patient is drawing clock with time given by administrator, which is 11:10 am. Administrator evaluates 12 digits in the clock, hour hands and pointing of the hour hands. Maximum score for is 5 points. Score 4 or less indicates possible cognitive impairment. The test took 3 minutes.
Postoperative Cognitive Dysfunction - Clock Drawing Test After Operation
Time Frame: 3rd day after operation
Clock drawing test with Baja scoring system is a test, where patient is drawing clock with time given by administrator, which is 11:10 am. Administrator evaluates 12 digits in the clock, hour hands and pointing of the hour hands. Maximum score for is 5 points. Score 4 or less indicates possible cognitive impairment. The test took 3 minutes.
