“…Administration of the UB-2 and 3D-CAM with skip pattern is an example of adaptive testing, which has been used to improve the efficiency of other assessments in older patients. [13][14][15][16] Such testing is facilitated by use of a computer-based platform where automatic skip patterns can be preprogrammed, and only the relevant items presented to the clinician to ask the patient. The "Delirium-READI" iPad App that we developed for the READI study is an example of a platform that facilitates adaptive testing.…”

BACKGROUND/OBJECTIVES: Systematic screening can improve detection of delirium, but lack of time is often cited as why such screening is not performed. We investigated the time required to implement four screening protocols that use the Ultra-Brief two-item screener for delirium (UB-2) and the 3-Minute Diagnostic Interview for Confusion Assessment Method (CAM)-defined Delirium (3D-CAM), with and without a skip pattern that can further shorten the assessment. Our objective was to compare the sensitivity, specificity, and time required to complete four protocols: (1) full 3D-CAM on all patients, (2) 3D-CAM with skip on all patients, (3) UB-2, followed by the full 3D-CAM in "positives," and (4) UB-2, followed by the 3D-CAM with skip in "positives." DESIGN: Comparative efficiency simulation study using secondary data. SETTING: Two studies (3D-CAM and Researching Efficient Approaches to Delirium Identification (READI)) conducted at a large academic medical center (3D-CAM and READI) and a small community hospital (READI only). PARTICIPANTS: General medicine inpatients, aged 70 years and older (3D-CAM, n = 201; READI, n = 330). MEASUREMENTS: We used 3D-CAM data to simulate the items administered under each protocol and READI data to calculate median administration time per item. We calculated sensitivity, specificity, and total administration time for each of the four protocols. RESULTS: The 3D-CAM and READI samples had similar characteristics, and all four protocols had similar simulated sensitivity and specificity. Mean administration times were 3 minutes 13 seconds for 3D-CAM, 2 minutes 19 seconds for 3D-CAM with skip, 1 minute 52 seconds for UB-2 + 3D-CAM in positives, and 1 minute 14 seconds for UB-2 + 3D-CAM with skip in positives, which was 1 minute 59 seconds faster than the 3D-CAM (P < .001). CONCLUSION: The UB-CAM, consisting of the UB-2, followed in positives by the 3D-CAM with skip pattern, is a time-efficient delirium screening protocol that holds promise for increasing systematic screening for delirium in hospitalized older adults.

“…29 The reward criterion for a task can be adjusted to push animals to their peak performance. From the rehabilitation perspective, varying the difficulty of the task allows optimally challenging subjects to keep them engaged in task for better learning 30 and to better match the complexity with skill level of the performer 31 than if the task difficulty is the same for all subjects.…”

Rodent tests of function have advanced our understanding of movement, largely through the human training and testing and manual assessment. Tools such as reaching and grasping of a food pellet have been widely adopted because they are effective and simple to use. However, these tools are time-consuming, subjective, and often qualitative. Automation of training, testing, and assessment has the potential to increase efficiency while ensuring tasks are objective and quantitative. We detail new methods for automating rodent forelimb tests, including the use of pellet dispensers, sensors, computer vision, and home cage systems. We argue that limitations in existing forelimb tasks are driving the innovations in automated systems. We further argue that automated tasks partially address these limitations, and we outline necessary precautions and remaining challenges when adopting these types of tasks. Finally, we suggest attributes of future automated rodent assessment tools that can enable widespread adoption and help us better understand forelimb function in health and disease.

“…Computerized adaptive testing (CAT) is a proven method for the efficient, reliable, and valid assessment of health-related functions 16 , 17 . CAT leverages item response theory to dynamically select the most relevant questions based on prior responses, resulting in more concise questionnaires with enhanced precision 18 , and reducing the administrative burden on patients 19 , 20 , which is similar to the LS-categorizing assessment rule.…”

Stroke survivors frequently experience difficulties in daily activities, such as bathing, feeding, and mobility. This study aimed to evaluate the reliability and validity of a computer-adaptive test-Longshi scale (CAT-LS) for assessing activities of daily living (ADL) in stroke survivors. This cross-sectional study collected data using an electronic application. The ADL function of stroke survivors in rehabilitation departments of hospitals was assessed using both the CAT-LS and BI. Correlations between the CAT-LS and Barthel index (BI) and concurrent validity were evaluated using Pearson’s correlation test and multiple linear regression. Interrater reliability was evaluated using the intraclass correlation coefficient based on a two-way random effect. The internal consistency of the CAT-LS was assessed using Cronbach’s coefficient (α) and corrected item-total correlations. Overall, 103 medical institutions in China were used in this study. In total, 7151 patients with stroke were included in this study. The CAT-LS classified patients into three ADL groups (bedridden, domestic, and community) with significantly different BI scores (P < 0.05). The CAT-LS results obtained using the decision-tree scoring model were consistent with the scores for each BI item. A strong correlation was observed between CAT-LS and BI (Pearson’s r: 0.6–0.894, P < 0.001). The CAT-LS demonstrated good internal consistency (Cronbach’s α, 0.803–0.894) and interrater reliability (ICC, 0.928–0.979). CAT-LS is time-efficient and requires < 1 min to administer. The CAT-LS is a reliable and valid tool for assessing ADL function in stroke survivors and can provide rapid and accurate assessments that reduce the burden on healthcare professionals. Further validation of this tool in other populations and settings is necessary.Study registration number: No.: ChiCTR2000034067; http://www.chictr.org.cn/showproj.aspx?proj=54770.
