AI-Based Pedestrian Detection and Avoidance at Night Using Multiple Sensors

In this paper, we present a pedestrian detection and avoidance scheme utilizing multi-sensor data collection and machine learning for intelligent transportation systems (ITSs). The system integrates a video camera, an infrared (IR) camera, and a micro-Doppler radar for data acquisition and training. A deep convolutional neural network (DCNN) is employed to process RGB and IR images. The RGB dataset comprises 1200 images (600 with pedestrians and 600 without), while the IR dataset includes 1000 images (500 with pedestrians and 500 without), 85% of which were captured at night. Two distinct DCNNs were trained using these datasets, achieving a validation accuracy of 99.6% with the RGB camera and 97.3% with the IR camera. The radar sensor determines the pedestrian’s range and direction of travel. Experimental evaluations conducted in a vehicle demonstrated that the multi-sensor detection scheme effectively triggers a warning signal to a vibrating motor on the steering wheel and displays a warning message on the passenger’s touchscreen computer when a pedestrian is detected in potential danger. This system operates efficiently both during the day and at night.

Emergent digital literacy in Chinese preschoolers: developmental patterns and associated predicators

ABSTRACT This study examined the emergence of digital literacy in early childhood among 2272 parents with at least one child under age six in central China. Findings revealed that: (1) there was a significant age difference in early digital literacy, with television literacy emerging first, followed by touchscreen, artificial intelligence, and personal computer literacy. Gender differences were only observed in television literacy; (2) the home location, home income, home digital resource (HDR), and parent’s age significantly correlated with young children’s general emergent digital literacy, while family structure, parent’s education, and occupation had significant correlations with some specific emergent digital literacy; HDR played a mediation role in the relationship between the home context factors and preschoolers’ emergent digital literacy. (3) age of the child, family structure, home income, and HDR significantly contributed to predicting preschoolers’emergent digital literacy. Implications for policy-making and parental education are also addressed.

The amygdala is not necessary for the familiarity aspect of recognition memory

Dual-process accounts of item recognition posit two memory processes: slow but detailed recollection, and quick but vague familiarity. It has been proposed, based on prior rodent work, that the amygdala is critical for the familiarity aspect of item recognition. Here, we evaluated this proposal in male rhesus monkeys (Macaca mulatta) with selective bilateral excitotoxic amygdala damage. We used four established visual memory tests designed to assess different aspects of familiarity, all administered on touchscreen computers. Specifically, we assessed monkeys’ tendencies to make low-latency false alarms, to make false alarms to recently seen lures, to produce curvilinear ROC curves, and to discriminate stimuli based on repetition across days. Three of the four tests showed no familiarity impairment and the fourth was explained by a deficit in reward processing. Consistent with this, amygdala damage did produce an anticipated deficit in reward processing in a three-arm-bandit gambling task, verifying the effectiveness of the lesions. Together, these results contradict prior rodent work and suggest that the amygdala is not critical for the familiarity aspect of item recognition.

A Vehicle Simulation Study Examining the Effects of System Interface Design Elements on Performance in Different Vibration Environments Below 3Hz.

This study aimed to explore the relationship between system interface elements' design features and interaction performance in simulated vehicle vibration environments. Touch screens have been widely used in vehicle information systems, but few studies have focused on the decline of touchscreen interaction performance and task load increase when driving on unpaved roads. The interaction performance (reaction time and task accuracy rate) with vibration frequencies below 3Hz (1.5, 2.0, and 2.5Hz) and different interface design elements was investigated employing a touch screen computer and E-prime software. The results indicate that vehicle vibration (below 3Hz) can significantly reduce interaction performance with a vehicle information system interface. An appropriate increase in the physical size of the interface design features (visual stimulus materials and touch buttons) can help to mitigate this negative effect of vibration. The results and findings of this study can be utilized for the design of information system interfaces as it relates to the vibration scenario of unpaved roads.

How do Autistic and Neurotypical Children’s Interests Influence their Accuracy During Novel Word Learning?

Word learning depends on attention – children must focus on the right things at the right times. However, autistic children often display restricted interests, limiting their intake of stimuli during word learning. This study investigates how category interests influence word learning in autism and neurotypical development. Autistic and neurotypical children matched on receptive vocabulary used a touch-screen computer to learn novel words associated with animals (high-interest stimuli) and objects (neutral-interest stimuli) via fast mapping. Response accuracy and speed were examined at referent selection, 5-minute retention, and 24-hour retention. Both groups identified meanings of novel words associated with unfamiliar animals and objects via mutual exclusivity with comparable accuracy. After 5 minutes, autistic children retained animal names with greater accuracy than neurotypical children. Autistic children showed a greater increase in their accuracy between 5-minute and 24-hour retention and outperformed neurotypical children across conditions after a night’s sleep. Across groups, 24-hour retention was predicted by number of target word repetitions heard at referent selection, indicating a relationship between fast mapping input and retention. However, autistic children were slower to respond correctly, particularly in the animal condition. For autistic children, superior word learning associated with high-interest stimuli was relatively short-term, as sleep appeared to consolidate their memory representations for neutral-interest stimuli. Although these results demonstrate that fundamental word learning mechanisms are not atypical in autism, slower response times may signal a speed-accuracy trade-off that could have implications for naturalistic language acquisition. Our findings also indicate favourable environmental conditions to scaffold word learning.

Concepts in Space: Enhancing Lexical Search With a Spatial Diversity Prime.

Informed by theories of embodied cognition, in the present study, we designed a novel priming technique to investigate the impact of spatial diversity and script direction on searching through concepts in both English and Persian (i.e., two languages with opposite script directions). First, participants connected a target dot either to one other dot (linear condition) or to multiple other dots (diverse condition) and either from left to right (rightward condition) or from right to left (leftward condition) on a computer touchscreen using their dominant hand's forefinger. Following the spatial prime, they were asked to generate as many words as possible using two-letter cues (e.g., "lo" → "love," "lobster") in 20 s. We hypothesized that greater spatial diversity, and consistency with script direction, should facilitate conceptual search and result in a higher number of word productions. In both languages, word production performance was superior for the diverse prime relative to the linear prime, suggesting that searching through lexical memory is facilitated by spatial diversity. Although some effects were observed for the directionality of the spatial prime, they were not consistent across experiments and did not correlate with script direction. This pattern of results suggests that a spatial prime that promotes diverse paths can improve word retrieval from lexical memory and lends empirical support to the embodied cognition framework, in which spatial relations play a crucial role in the conceptual system.

Design and Performance Analysis of Monitoring System for Seed Metering and Fertilization of Precision Seeder Based on Photoelectric Sensor

In order to realize accurate monitoring of wheat sowing and fertilization process and ensure efficient and reliable sowing operation, an integrated monitoring system of wheat sowing and fertilization based on variable-distance photoelectric sensor is designed. The monitoring system includes the hardware circuit of STM32F103 lower computer and the human-machine interface of the upper computer touch screen. The hardware circuit of the lower computer is composed of OH-1021 photoelectric sensor, signal shaping and amplifying circuit, encoder speed acquisition module, communication module, central processor, and peripheral circuits. The information of seed fertilizer flow and seed fertilizer shaft rotation is obtained through the reflective photoelectric sensor and rotary encoder respectively to judge the running state of sowing. The information is transmitted to the human-machine interface of the upper computer touch screen of MCGS by means of Modbus communication protocol. In the experimental species, the single seed monitoring accuracy of the monitoring system reaches 98.6%. Compared with the test results of the performance test bench of the seed metering device, the monitoring error of the monitoring system is less than 0.3%, the monitoring error of the replay rate is less than 0.6%, and the monitoring accuracy of the seeding amount is greater than 94%. The simulation results of the seed metering monitoring circuit of the lower computer show that the detection distance of the amplifier circuit to the photoelectric sensor of the seed tube changes by [4 mm, 7 mm]. The communication test results of the upper and lower computers show that the accuracy of data transmission reaches 100%, the monitoring system shows that the accuracy of fault detection exceeds 90%, and the response time of lacking, blocking, and leaking is less than 0.3 s. The monitoring system realizes high-precision monitoring of wheat seed metering and fertilization, which is helpful to improve the quality of wheat planting.

The Effectiveness of Detecting Thematic Relations of Objects in 3–6 Years Old Children

In this work, the ability of preschoolers aged 3–6 to detect and understand the thematic connections of objects was assessed. Children (95 children; 53 girls and 42 boys) of four age groups of 3, 4, 5 and 6 years old (respectively, 17, 33, 18 and 27 children) solved two tasks aimed at the detection of thematic relations of objects within the framework of the standard “yes–no” procedure. In the first task, it was required to indicate whether the image of the shown object was relevant to a given context (the “object-context” task, O–C), and in the second – whether two objects were related thematically (the “object–object” task, O–O). A touch screen computer was used to present images and record motor responses. For each task, we measured the accuracy scores (the proportion of correct responses) and the delay in the motor response “yes” or “no” relative to the moment the image was presented (reaction time). Two components of the reaction time were analyzed separately: the duration of the latent phase and the duration of the overt movement towards the response button. With age, the accuracy of solving both tasks increased, and the time required to discover the thematic connection (reaction time) decreased. At the same time, the accuracy scores were lower, and the detection time was longer in the O–O task compared to the O–C. The gender of the child did not affect the accuracy value, and affected only the duration of the motor (but not the latent) phase of the motor response, and only in the O–O task. The data obtained show that (i) the O–O task is more difficult than the O–C task, and that this may be due to the necessity to activate the thematic links of two objects in the O–O task instead of just one, as in the O–C task, and (ii) the process of activation of thematic links probably does not end in the latent phase of the motor response and continues during its movement phase. The question of the extent to which the success and duration of the process of detecting the thematic links of objects can limit the success of cognitive planning in preschoolers aged 3–6 is also discussed.

Sensor-based implicit authentication through learning user physiological and behavioral characteristics

Nowadays, a large amount of users’privacy data is stored in mobile intelligent devices, and authentication systems have become an important defense to protect that data. The traditional explicit authentication, however, is under significant threat from a great deal of side channel attacks, such as those based on computer vision and touch screen attacks. Users’authentication keys are facing a high risk of leakage, whereas implicit authentication is one of the effective methods to resist various side channel attacks. Nevertheless, existing user implicit authentication approaches still have weaknesses in security and usability, which increase users’authentication burdens and pose potential safety issues. To address this problem, our paper proposes a user implicit authentication approach based on physiological and behavioral characteristics, using the most commonly performed actions in daily life to pre-authenticate users. In our method, multiple sensors are utilized to extract physiological and behavioral characteristics of users, and the sensor data is fused by aligning the extracted characteristic data and using the Kalman filter to reduce its noise. Users’authentication results can be determined by comparing the similarities between their reference and authentication samples using the siamese neural network. The experimental results show that our approach improves the performance of implicit authentication while ensuring its security and usability.

Preliminary Assessment of Siamang (Symphalangus syndactylus) Cognition Using Digital Cognition Testing Software and Touchscreen Technology

Studies of nonhuman primate cognition have traditionally employed subjects from the monkey (Cercopithecoidea) and ape (Hominidae) lineages, with relatively much less examination of the phylogenetically intermediate gibbons (Hylobatidae). To begin to rectify this gap in our understanding of primate cognition, we used a short-term training and testing method to preliminarily evaluate siamang gibbon (Symphalangus syndactylus) performance on a battery of standardized cognitive tasks, using Monkey CANTAB cognition testing software (Lafayette-Campden Neuroscience) and a computer touchscreen apparatus. Five different operant tasks examining distinct perceptual and cognitive functions were used to train and test each subject over a period of five weeks. Over 1900 cognitive testing trials were completed with three subjects. Despite limited training and testing opportunity, all siamangs achieved proficiency scores well above chance (> 65%) in both Concurrent Discrimination and Spatial Working Memory tasks. Over the limited training opportunities available, our subjects did not achieve proficiency in Delayed Match-to-Sample, Paired Associates Learning, or Conditional Visual Discrimination tasks; however, subjects did exhibit (to varying degrees) improved performance in these tasks, suggesting that additional training may lead to higher proficiency and that siamangs demonstrate effective, task-based learning capabilities. We present one of the first successful tests of a hylobatid ape using touchscreen cognitive testing methods and demonstrate that hylobatids can be evaluated using the same methods now commonly employed in tests of other nonhuman primates. Further, our testing regime proved to be behaviorally rewarding for our subjects, suggesting that hylobatids may benefit from advanced forms of interactive cognitive enrichment.

Evaluation of two methods for detection of viable Bacillus anthracis simulant spores in maritime environmental samples.

Analytical methods exist to detect biothreat agents in environmental samples during a response to biological contamination incidents. However, the coastal zone facilities and assets of the US Coast Guard (USCG), including response boats in diverse geographical areas and maritime environmental conditions, can pose complex and unique challenges for adapting existing analytical detection methods. The traditional culture (TC) and the rapid viability polymerase chain reaction (RV-PCR) methods were evaluated for their compatibility for maritime environmental surface and grab sample analysis to detect spores of Bacillus thuringiensis subspecies kurstaki (Btk), a surrogate for Bacillus anthracis. The representative samples collected from a USCG installation included surfaces, such as aluminum on boats, nonskid tread on decks of watercraft, computer touchscreens, and concrete piers, and grab samples of boat washdown water, soil, vegetation, and gravel from surrounding areas. Replicate samples were spiked with Btk spores at two to three tenfold increasing levels and analyzed. Out of a total of 150 samples collected and analyzed, the TC method gave 10 false-positive and 19 false-negative results, while the RV-PCR method-based analysis resulted in 0 false-positive and 26 false-negative results. An abundance of microbial background and particulates in some samples interfered with true results, while both methods gave similar results for samples with low microbial background and particulates. Improved and high-throughput sample processing methods are needed for analysis of complex environmental samples.

Measuring recognition visual acuity in young children – testability with the Waterloo Differential Acuity Test (WatDAT)

ABSTRACT Clinical relevance Visual acuity measurement is important for the detection and monitoring of eye disorders. Developing accurate and sensitive visual acuity tests suitable for young children is therefore desirable. Background Recognition or form visual acuity (VA), which is measured with matching in children aged 3 years and up, is more sensitive for detecting visual deficits compared to resolution VA. The Waterloo Differential Acuity Test (WatDAT) is a proposed recognition VA test using the concept of identifying the “odd one out” among distractors. The WatDAT is expected to be cognitively easier than matching tests and therefore may be used in younger children. The purpose of this study is to investigate the testability of the WatDAT paradigm in children aged 12–36 months, and to determine the optimum format and number of distractors. Methods Fifty-one typically-developing children aged 12–36 months participated in the study. Data for Patti Pics (PP) and Face targets (FT) were collected for formats with 3, 4 and 5 distractors. The targets were presented binocularly on a computer touch screen at 30 cm. The task was to touch the face among identical non-faces or a house among circles. Following initial training, there were 5 presentations for each distractor format. Testability was defined as correctly identifying at least 4/5 presentations and was also determined for uncrowded PP symbols using matching. Results Of participants aged 18–36 months, 87% could perform the WatDAT PP targets with 3 distractors compared to 68% for the FT, while 48% could perform matching with PP. The testability for FT increased to 85% for children ≥22 months. Younger children showed lower testability. For the 3 distractor format, PP targets gave 9% testability in children 12 to <18 months, and FT gave a testability of 16% in children 12 to <22 months. Conclusion WatDAT testability is higher than matching VA tests. This indicates that the newly developed WatDAT has potential for measuring recognition VA in children 18 months and older.

478 Enhancing Technology Interface in the Dissection Room (DR)

Abstract Aim Anatomy teaching increasingly utilises technology alongside dissection to improve anatomy teaching. Student use of the touchscreen computers in dissection sessions at the University of St. Andrews was infrequent, with students lacking confidence in touchscreen use. The aim of this QI project was to improve medical student confidence and increase the use of touchscreen computers in the DR during dissection sessions. Method A data-collection tool was designed and tested. It included 4 Likert-style and one blank space question. 111 baseline responses from 3rd-year medical students were collected over 1 week in November 2021. Documentation was optimised for touchscreen usage. Cycle 2 was collected from the same cohort, with 83 responses. The second intervention introduced styluses. Cycle 3, with 85 responses, was collected. Results Question 1 examined awareness of touchscreen function. Positive responses (agree and strongly agree) increased from 76.5% to 95.2%, then 97.7% after interventions 1 and 2 respectively. Positive responses for question 2, examining confidence, improved from 53.2% to 88.0%, then 96.5%. Positive responses to question 3, examining the frequency of touchscreen use, improved from 49.6% to 91.6% then 92.9%. Positive responses for question 4, examining how useful touchscreens were for student learning, improved from 70.3% to 94.0%, then 97.7%. Blank space questions demonstrated positive opinions of changes made in the dissection room. Conclusions The significant and sustained increase in positive responses regarding student confidence, touchscreen use and the usefulness of touchscreens as an adjunct to dissection in the DR demonstrated significant improvement in the use of the facilities and student educational experience.

Incompatibility Influences Cursor Placement When Pointing to Images of Cups.

As images are used within graphical user interfaces to signify menu selection, it is important to understand how image properties can influence cursor placement online. Objects have multiple dimensions that create potential ambiguity and Stroop-like confusions for the operator if a previously habitual response conflicts with the required response. To examine the impact of compatibility and other contextual factors, 41 participants used a computer Mouse or touch screen to place the cursor upon images of full or empty cups that varied in size, and direction of handle. Cursor placements took longer using the Mouse than touch screen. Although participants were placing the cursor on images, the size of the cup, whether it was empty or full, and the handle orientation interacted in their effects upon response duration and cursor placement. The effects of cup size reversed for empty cups or those with incompatible handles. Context can influence cursor placement. Perceived spillability influenced precision requirements, and the cup handle can serve as target or a flanking distractor. Image content can influence screen hotspots. As performance can change with cup spillability, this bodes well for attempts to detect intent from cursor trajectories.

Perceptions of community members in Australia about the risk factors, symptoms and impacts of dementia: A cross-sectional questionnaire study.

Ensuring that the Australian public has an accurate understanding of the characteristics of dementia may assist in improving timely detection of dementia. This cross-sectional questionnaire study aimed to examine community members' perceptions of the risk factors, symptoms and impacts of dementia. Participants were recruited from outpatient units at a major regional hospital and were aged at least 18 years, a patient or an accompanying support person, did not have a dementia diagnosis, had sufficient English knowledge and were well enough to complete a survey. Participants completed a web-based survey on a touchscreen computer including items exploring knowledge of dementia risk factors, symptoms and perceived impacts if they or a loved one had dementia. Counts and proportions were calculated and perceived impacts of dementia were compared for self versus loved one using a χ2 test. Of 353 eligible individuals approached, 208 consented and were included in the study. Between 30% and 61% (n=62-127) of participants believed modifiable factors such as high alcohol consumption and high blood pressure were associated with increased risk of dementia. While a majority of participants (87-96%; n=164-181) identified memory-related symptoms, less than one-third recognised behavioural symptoms. Participants were more likely to identify emotional and practical impacts compared to physical or social impacts as most difficult if they or a loved one had dementia. There remains a need for increased community education to address knowledge gaps regarding modifiable risk factors, behavioural symptoms and potential impacts of dementia on the individual diagnosed and their carers.

The ability to define subtypes of idiopathic OAB remains unclear however, expert consensus suggests that OAB phenotypes exist that reflect different pathophysiologic characteristics. The objective of this study is to utilize a non-invasive, validated sensation-meter tool and hydration protocol in order to characterize bladder sensations in individuals with OAB. METHODS: This is prospective cohort study of adult men and women aged 18 years and older with OAB and without OAB recruited through the Vanderbilt Research Notification Distribution List. The bladder sensation meter is a touch-screen computer tablet-based application (LabView, National Instruments, Austin, TX) for self-recorded sensory data. A standardized oral hydration protocol was used, in which participants were instructed to drink two liters of Gatorade-G2® (low-sugar). The interface allows each participant to quantify his/her bladder sensation in real-time. RESULTS: Preliminary study results included 8 female subjects: 4 OAB and 4 Controls. The sensation of tingling was reported more often in OAB group compared to controls (n=7 versus n=2) and tense was reported more often in controls (n=5 versus n=0 for OAB). Only pressure and tingling were reported sensations in the OAB group. Subjects in the OAB group demonstrated shorter time intervals to first desire and strong desire as compared to controls (Table 1/Figure 1). CONCLUSIONS: Self-recorded sensory data has demonstrated feasibility and reproducibility in healthy controls and in those with OAB and is an innovative non-invasive tool to better understand bladder sensations in subjects with OAB. This tool allows for development of sensation-capacity curves and frequency/distribution of sensation events that can be used to delineate different clinical OAB phenotypes.

Design and Application of Interactive Algorithm for Advertising Media Screen Based on Smart Sensor

Touch is one of the most important human senses. With the popularization of touch-screen mobile phones, tablet computers, and other devices, touch-screen interactive technology has become a norm in people’s daily lives, and advertisements that were once dominated by vision and hearing have added an interactive experience in the dimension of touch. Traditional advertising media screens can only complete simple information dissemination functions and cannot interact with users in a two-way manner. They can only receive information one-way and passively and lack interactivity. Touch-screen interactive advertising forms a good interaction with the target audience, thereby disseminating advertising information to achieve the purpose of promotion or brand image building. This paper designs a set of advertising media screen interaction systems based on smart sensors, including a gesture interaction module, a remote interaction module, and a touch interaction module. The gesture interaction module can recognize 5 static gestures and send gesture commands to control the advertising media screen. The remote interaction module can remotely control the advertising media screen, and the touch interaction module can control the advertising media screen through the touch screen. According to the functional requirements, the overall design of software and hardware is given, and the technical background of each module of the software is introduced. Next, the depth image-based gesture recognition method is studied. The number of fingers and the center distance feature are fused as feature vectors, and the weighted template matching method is used to classify and recognize gestures. Finally, the design and implementation of the interactive system are introduced.

A Food for All Seasons: Stability of Food Preferences in Gorillas across Testing Methods and Seasons.

Simple SummaryWe assessed food preferences in three adult male zoo-housed gorillas over a period of 20 months. We used paired-choice tasks on a computer touchscreen and we also presented food pairings by hand using PVC tubes and compared the stability of preferences across methods and seasons. In addition, we assessed whether preferences were stable across offerings within a session. To further validate the use of images on touchscreens to assess food preferences, we showed that these gorillas chose images of highly preferred food items when these images were paired with images of their less preferred foods. These tests can help us understand the stability of animals’ preferences and whether preferences are dependent on the larger test context.Decisions about which foods to use during training and enrichment for captive animals may be based on invalid assumptions about individuals’ preferences. It is important to assess the stability of food preferences given that one-time preferences are often used to inform which items are offered over a longer period of time. Presenting preference assessments using images of food items allows control over factors such as size, scent, and inadvertent cueing but requires validation. We presented three male gorillas with choices between randomly selected pairs of actual food items from their morning meal using PVC feeders. We also presented the gorillas with two-alternative forced-choice tests between images of these foods on a touchscreen computer. Ranked preferences were correlated across method and seasons. Furthermore, gorillas selected images of preferred over less preferred foods in a validation task on the touchscreen. However, selections of some food items changed within sessions, suggesting that preference may be relative to other contextual factors. Researchers should assess how choices affect subsequent preferences to understand whether animals demonstrate absolute preferences for particular food items, or prefer variety.

Bias Against Older Adults in Young Children and Their Parents

Parents are an important source of social learning for their children. However, little is known about whether they play a role in shaping ageist attitudes in children. We investigated how parents’ biases against older adults would relate to those of their children and how preferences would differ depending on the child’s age. Participants were 56 parent-child dyads with the children’s age ranging from four to eight years (parents mean age = 36.95, SD = 5.49). Children were divided into three age groups, preschool (n = 18), early school-aged (n = 18), and middle school-aged (n = 20). Children and parents completed a picture rating task, which included the evaluation of 28 images of younger and older adults faces. Children used a smiley-face rating scale on a touch-screen computer, and parents used a sliding preference scale for their ratings. It was found that both, children (t(55) = 5.47, p < .001, d = 0.73) and their parents (t(55) = 2.05, p = 0.045, d = 0.27), gave significantly more positive ratings to younger than to older adults, which is consistent with an underlying bias for younger adults. Contrary to our expectations, this preference in children held across age groups and was not associated with parental preferences. Nevertheless, it has been shown that ageist preferences can already be detected in childhood. Further longitudinal research is needed to track the development of ageism from childhood on, and efforts to combat ageism should be addressed not only to adults, but to children as well.

Integrating Touchscreen-Based Geriatric Assessment and Frailty Screening for Adults with Acute Myelogenous Leukemia to Drive Personalized Treatment Decisions

Background: Acute Myeloid Leukemia (AML) is a disease of older adults, with a median age of 68 years at diagnosis. The NCCN guidelines recommend comprehensive geriatric assessments (GA) be included in clinical practice to guide treatment decisions. Utility of GA in older AML patients in a real-world environment is not yet established. We tested the feasibility of using a modified GA (mGA), administered by patient self-report on a touchscreen computer, real-time use and utility by clinicians and the correlation of mGA results on treatment decision-making.Methods: 77 newly diagnosed patients were recruited from three sites to complete a tablet-based mGA screening at a treatment decision visit. The mGA includes four domains: age, activities of daily living (ADLs), instrumental ADLs, and comorbidities. Survey results along with history of falls was used to create the Frailty Index (FI). Providers were asked what they thought the fit/frailty status of the patient was before viewing the results on a dashboard. After viewing the survey results, the clinician discussed the treatment plan with the patient. Patients received intensive or non-intensive therapy. Additional information was captured on clinical trial enrollment. Baseline and 3 month surveys recorded presence and severity of 8 symptoms using the Edmonton Symptom Assessment Scale (ESAS) with 0=no symptom and 10=worst possible symptom and quality of life using the Functional Assessment of Cancer Treatment: Leukemia (FACT-LEU).Results: Participants had a median age of 71 years ( range:61-88y); 50% were female, and 87% white. Frailty Index results for 76 patients were 28 (36.4%) fit, 25 (32.5%) intermediate, and 23 (29.9%) frail. (One patient did not complete the mGA). 52 of 77 (69%) enrolled patients were alive at 3 months; 21(27%) died and 4 (5%) were lost to follow-up. Providers were asked the fit/frailty status prior to seeing the results of the mGA. Of 75 provider responses, results were 27 (36.0%) fit, 29 (38.7%) intermediate, and 19 (25.3%) frail. There was 63% (n=47) provider concordance with the mGA result. There was more agreement with fit (n=22, 81.5%) and frail status (n=11, 57.9%) and less with intermediate (n=14, 48.3%). Of the 25 of 75 (33.%) provider reports that indicated that the mGA result influenced the treatment decision, 6 patients (5 fit, 1 intermediate) received intensive treatment, 15 received non intensive treatment (1 fit, 6 intermediate, 8 frail) and 4 enrolled in a clinical trial (1 fit, 2 intermediate, and 1 frail). Significant symptom improvement at 3 months was seen for drowsiness, lack of appetite, shortness of breath, and anxiety. FACT Leu results did not change over 3 months. Providers reported an average of 4.45 minutes to review the dashboard. Patients were able to complete the surveys unassisted in an average time of 16.24 minutes.Discussion: There was nearly 40% discordance between the provider and mGA, with the most discordance on the intermediate fit status. However, results of the mGA influenced treatment decision making in one third of provider/patient interactions. Further analysis of the mGA domains is warranted to see if additional insights can be gained. With time, some symptoms improve and others don't. This points to the opportunity to direct resources towards symptom assessment during treatment. Feasibility was demonstrated in this study as providers received the aggregated results in real time and reviewed them in less than 5 minutes. In addition, patients were able to complete the survey unassisted without disturbing clinic operations. [Display omitted] DisclosuresNo relevant conflicts of interest to declare.
