Feasibility of the Modified Telephone Interview for Cognitive Status (M-TICS) in the peri-operative environment.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
introductionPeri-operative neurocognitive disorders are common among older adults presenting for surgery and anaesthesia. Cognitive screening is recommended to identify patients at risk for adverse neurocognitive outcomes, though the most appropriate peri-operative tool remains debated. Remote assessment methods may be advantageous, but they need robust validation. We aimed to examine the feasibility and validity of the Modified Telephone Interview for Cognitive Status (TICS-M) among older adults and provide recommended TICS-M scores to identify those most at risk of poor postoperative cognitive outcomes.
methodsAs part of a prospective longitudinal study with 215 older adults living in the community or scheduled for elective surgery, we conducted the modified, 22-item, 50-point version of the TICS remotely, followed by in-person assessments using two common cognitive screening tools: the Mini-Mental State Examination (MMSE); Alzheimer's Disease Assessment Scale Cognition Subscale (ADAS-Cog); and a comprehensive neuropsychological and functional assessment.
resultsThe TICS-M was feasible and acceptable, with a completion rate of 86%. TICS-M scores correlated with scores on the MMSE (r = 0.61, p < 0.001) and ADAS-Cog (r = -0.55, p < 0.001) at baseline, and associations remained consistent at 12- and 24-month follow-up. After controlling for age, sex and education, baseline performance on the TICS-M was independently associated with subsequent cognitive impairment at 12 months (OR 0.84, 95% CI 0.77-0.92, p < 0.001) and 24 months (OR 0.84, 95% CI 0.76-0.94, p = 0.001). A TICS-M score of 32.5 was the optimal threshold to identify people with cognitive impairment (0.76, 95% CI 0.70-0.82, p < 0.001). DISCUSSION: The TICS-M is a feasible, valid and reliable remotely administered tool that shows utility in the peri-operative environment. We recommend its implementation into routine clinical practice for remote pre-operative assessment in patients aged ≥ 65 y scheduled for surgery and anaesthesia.
