Registered outcomes 10
Each outcome the trial registered, primary first, in ClinicalTrials.gov's words.
| List | Outcome | Time frame | Description | Source |
|---|---|---|---|---|
| Primary | Mini-mental State Exam (MMSE) | Pre-operatively, at 6 months, 12 months, and five year post-operatively. | Mini-Mental State Examination (MMSE) measures global cognitive function. Score ranges from 0-30; a score of 0 indicates severe cognitive impairment and a score of 30 indicates no cognitive impairment. Higher scores indicate better outcome. | ClinicalTrials.gov |
| Primary | Digit Span test (verbal) | Pre-operatively, at 6 months, 12 months, and five year post-operatively. | Measures simple attention. In the first part, subjects are required to recall and recite digits in forward sequence (0-16 points), the second part requires subjects to recall and recite digits in backward sequence (0-14 points). Higher scores indicate better outcome. | ClinicalTrials.gov |
| Primary | Stroop Color-Word Test (Golden version) | Pre-operatively, at 6 months, 12 months, and five year post-operatively. | Stroop Color-Word Test measures sustained attention. Raw score is the number of answers correct out of 100. Higher scores = better outcome. | ClinicalTrials.gov |
| Primary | Hopkins Verbal Learning Test-Revised (HVLT-R) | Pre-operatively, at 6 months, 12 months, and five year post-operatively | Measures verbal learning and memory. Score ranges from 0-36; a score of 0 indicates no words recalled and a score of 36 indicates perfect recall. Higher scores indicate better outcome | ClinicalTrials.gov |
| Primary | Hayling Sentence Completion Test | Pre-operatively, at 6 months, 12 months, and five year post-operatively | Measures executive functioning. Overall scaled score ranges from 1-10; a score of 1 indicates impaired function and 10 indicates very superior function. Higher score indicates better outcome | ClinicalTrials.gov |
| Primary | Spatial Span Test (visuospatial) | Pre-operatively, at 6 months, 12 months, and five year post-operatively | Assesses attention, short-term and working memory. Two parts, the first part requires subjects to physically point at the digits shown to them in forward sequence (0-16 points), the second part requires subjects to point the digits in backward sequence (0-16 points). Higher scores indicate better outcome. | ClinicalTrials.gov |
| Primary | d2 Test of Attention | Pre-operatively, at 6 months, 12 months, and five year post-operatively | Assesses sustained and selective attention. The score is calculated as: Total Number of Items minus Errors. Higher scores indicate better outcome. | ClinicalTrials.gov |
| Primary | Brief Visuospatial Memory Test-Revised (BVMT-R) | Pre-operatively, at 6 months, 12 months, and five year post-operatively. | Measures visuospatial learning and memory First Section assess immediate recall where raw scores range from 0-36; a score of 0 indicates no figures recalled and a score of 36 indicates perfect recall. Second Section assess delayed recall ( 25-minute delay) with a score range from 0-12. A higher score indicates better recall outcome. | ClinicalTrials.gov |
| Primary | Trail Making Test Part B | Pre-operatively, at 6 months, 12 months, and five year post-operatively. | Executive functioning is scored by the total time in seconds required to complete the task. The time to complete each task is recorded as a score. A higher score indicates poor performance and less time indicates better performance. | ClinicalTrials.gov |
| Secondary | Mood and Psychosocial impact of cochlear implants on older adults | Pre-operatively, at 6 months, 12 months, and five year post-operatively. | Psychosocial well being was measured using the Geriatric Depression Scale (GDS), a 30-item questionnaire designed for rating depression for older adults. Scores considered "normal" range between 0-9. Scores 10-19 are considered "mild depression," and 20-30 suggest "severe depression." | ClinicalTrials.gov |
