To Investigate the Influence of Surgery and Anesthesia on Elderly Population by Using the Comprehensive Geriatric Assessment

Study Overview
=================
Brief Summary
-----------------
Aging is a universal and progressive physiological phenomenon clinically characterized by degenerative changes in both the structure and the functional capacity of organs and tissues. A comprehensive geriatric assessment (CGA) has now become a standard assessment for caring for the elderly. CGA is a multidisciplinary team with the goal of improving the overall well-being of the elderly. It encompasses screening, diagnosis and treatment of the elderly. In this study, we use the comprehensive geriatric assessment to study the effects of surgery and anesthesia on elderly patients.

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Mini-Mental Status Examination | The Mini-Mental Status Examination is a screening tool for dementia. The investigator asks the patient a series of questions to which the patient answers to his or her best ability. Minium score of zero and a maximum score of 30. Lower value represents a worse outcome. A score of less than 24 is considered abnormal. | Before general anesthesia till 48-hours post-anesthesia. | 
| Geriatric Depression Scale - 15 | The Geriatric Depression Scale (short form) is a screening tool for depression. It is a questionnaire composed of 15 questions. The investigator asks the patient 15 questions in which the patient answers yes or no. Each question weighs 1 point with a minimum score of zero and maximum score of 15. The higher the score, the more likely depression is present. A score of 0 to 5 is normal. A score greater than 5 suggests depression. | Before general anesthesia till 48-hours post-anesthesia. | 
| Confusion Assessment Method | The Confusion Assessment Method is a screening tool for delirium. It comprises of four parts: (1) acute onset and fluctuating course, (2) inattention, (3) disorganized thinking, and (4) altered level of consciousness. (1) Acute onset and fluctuating course has two questions and the rest with one question each. The investigator conducts the assessment with the patient answering yes or no to each question. Delirium is diagnosed under these scenarios: yes to all four questions, yes to (1)+(2)+(3), yes to (1)+(2)+(4). | Before general anesthesia till 48-hours post-anesthesia. | 
| Barthel Index | Barthel Index is an ordinal scale used to measure performance in ADL (activities of daily living). It comprises of ten variables describing ADL. A minium of zero and a maximum and 100 is scored. Higher score reflects greater ability to function independently. 60 or less is classified as dependent. Scores of 0-20 indicate total dependency, 21-60 indicate severe dependency, 61-90 indicate moderate dependency, and 91-99 indicates slight dependency | Before general anesthesia till 48-hours post-anesthesia. |
