Monitoring signs and symptoms using decision support tools (DST) is one approach that could help improve early detection ensuring timely treatment and effective care. Objective To identify and analyse decision support tools available to support detection of infection in older people (> 65 years). Methods A scoping review of the literature 2010–2021 following Arksey and O’Malley (2005) framework and PRISMA-ScR guidelines. A search of MEDLINE, Cochrane, EMBASE, PubMed, CINAHL, Scopus and PsycINFO using terms to identify decision support tools for detection of infection in people > 65 years was conducted, supplemented with manual searches. Results Seventeen papers, reporting varying stages of development of different DSTs were analysed. DSTs largely focussed on specific types of infection i.e. urine, respiratory, sepsis and were frequently hospital based ( n = 9) for use by physicians. Four DSTs had been developed in nursing homes and one a care home, two of which explored detection of non- specific infection. Conclusions DSTs provide an opportunity to ensure a consistent approach to early detection of infection supporting prompt action and treatment, thus avoiding emergency hospital admissions. A lack of consideration regarding their implementation in practice means that any attempt to create an optimal validated and tested DST for infection detection will be impeded. This absence may ultimately affect the ability of the workforce to provide more effective and timely care, particularly during the current covid-19 pandemic.}, number={1}, journal={BMC GERIATRICS}, author={Masot, Olga and Cox, Anna and Mold, Freda and Sund-Levander, Martha and Tingstrom, Pia and Christelle Boersema, Geertien and Botigue, Teresa and Daltrey, Julie and Hughes, Karen and Mayhorn, Christopher B. and et al.}, year={2022}, month={Jul} } @article{ferreri_mayhorn_2022, title={Identifying and understanding individual differences in frustration with technology}, ISSN={["1464-536X"]}, DOI={10.1080/1463922X.2022.2095458}, journal={THEORETICAL ISSUES IN ERGONOMICS SCIENCE}, author={Ferreri, Nina R. and Mayhorn, Christopher B.}, year={2022}, month={Jun} } @article{ferreri_mayhorn_2021, title={That's Not What We Expected: Examining Technology Expectations and Malfunctions on Frustration}, ISSN={["2169-5083"]}, DOI={10.1177/10648046211007709}, abstractNote={Technology malfunctions and expectations for technology performance influence user attitudes and behaviors regarding that technology.

A one-group pretest-posttest design was used, and the data were analyzed using multilevel modeling and repeated-measures correlation tests. The results show a non-significant interaction effect of prior experience and gender on students' CS learning and monitoring accuracy. We found that gender significantly interacted with students' CS learning and monitoring accuracy, primarily specificity. In particular, UMC progression was able to reduce the gender gap in CS performance, and improved male monitoring accuracy. The results also showed a significant positive correlation between students' CS performance and sensitivity, and negative correlation with specificity.

In this task, the Convoy Leader decision-making paradigm developed by Lyons and Stokes (2012) was adapted to address advisor pedigree such that the human and automated information sources could be of high or low pedigree. Two hundred participants were asked to make eight decisions regarding the route taken by a military convoy based on intelligence (e.g., past insurgent attacks, Improvised Explosive Devices (IEDs) detected, etc.) provided by two information sources (human and automation) of varying degrees of pedigree. In two of these eight decisions, the decision-aids provided conflicting information.

As situations with two decision-aids of uneven pedigree can easily arise, it is critical to understand how operators are biased towards a decision-aid of a certain source type and pedigree.A decision-making task similar to the paradigm of Convoy Leader (Lyons and Stokes, 2012) was given to participants, where a military convoy route had to be selected in the presence of IEDs and insurgent activity. We measured behavioral reliance and trust attitudes. Pedigree was manipulated via controlled adviser descriptions, in a manner consistent with past investigations (Madhavan and Wiegmann, 2007a).We found a trust bias towards the human adviser, reversed only when there is a far greater pedigree in the automated adviser. Trust attitudes were also strongly indicative of reliance behaviors.Pedigree is a strong influencer of trust in a decision-aid and biased towards human advisers.

The merits of traditional metrics like the planning time index, buffer index, and travel time index are compared with newer ideas like complete cumulative distribution functions and mean/variance combinations. The question is: what is the quality of information about real-time reliability provided by these various options? This paper compares these metrics in the context of probe-based observations of travel times and rates. Also, a new idea for a pairwise metric, the root mean square travel rate τ rms in conjunction with the standard deviation σ τ .

We provide an example of using LCA to analyze a hazardous behavior: prescription medicine sharing and borrowing. Four distinct groups of people—ranging from abstainers to at-risk sharers—are identified and discussed.

The purpose for the current research was to determine whether symbol warning components could be improved further, whether the addition of text enhanced comprehension uniformly across symbols, and whether results varied by the application of different interpretation standards (coding schemes). METHOD: A total of 11 warning labels were examined: four new symbols plus the existing baseline symbol, each in versions with and without text, plus a text-only condition. Participant interpretation accuracy and preferences were assessed during face-to-face interview sessions. RESULTS: For symbol-only conditions, several candidate symbols outperformed the existing symbol, one substantially so. The effect of adding text to symbols varied significantly by symbol. Symbol plus text and text-only conditions performed equivalently, generally exceeded symbol-only conditions, and often surpassed the American National Standards Institute benchmark of 85% accurate interpretation. CONCLUSIONS: The research effort has identified a teratogen symbol and warning that outperforms the one currently in use. The effort has also identified important pragmatic and conceptual issues that should inform future work to improve medication labeling and other hazard communication.

Sharing prescription medication places individuals at risk for diverse consequences, and further research regarding medication loaning and borrowing behaviors and their associated consequences is merited.}, number={6}, journal={AMERICAN JOURNAL OF PUBLIC HEALTH}, author={Goldsworthy, Richard C. and Schwartz, Nancy C. and Mayhorn, Christopher B.}, year={2008}, month={Jun}, pages={1115–1121} } @article{kim_mayhorn_2008, title={Exploring students' prospective memory inside and outside the lab}, volume={121}, ISSN={["1939-8298"]}, DOI={10.2307/20445459}, abstractNote={This study compared activity-based intentions with event- and time-based intentions.

This study examined adolescents' interpretations of and preferences for warning symbols and statements related to pharmaceuticals with teratogenic properties.A total of 200 adolescents interpreted one of four warning symbols and four warning statements. Responses were coded using an established three-tier coding system. Symbol preferences were elicited. Interpretation accuracy and symbol preferences were analyzed by symbol and statement.The symbol in use on medication labels at the time of the study elicited nearly goal levels of interpretation accuracy; however it exceeded allowable levels of critical confusion. An alternative symbol elicited more fully correct responses than the existing symbol and was preferred to the existing symbol by a margin of 2 to 1. Yet another symbol was most preferred despite eliciting fewer correct interpretations. The impact of warning statements on overall warning interpretation varied by statement and statement-symbol combinations. At least one statement appeared to lessen the overall message of caution, and few adolescents expressed an awareness of risk if one "may become pregnant" until explicitly informed of this risk.Comprehension of medical warning symbols and statements among adolescents is an important public health issue. Those involved in adolescent health education and research have considerable theoretical and practical tools for approaching the development and evaluation of such warning messages.

In the standard form of the task, participants must remember to press a key when a certain class of items is encountered. To evaluate output monitoring, event-based cues were repeated and participants were asked to press a different key if they could remember that an earlier response was made to a particular cue. Younger adults forgot fewer of their successful responses, but displayed a distinct bias to claim that they had responded earlier when actually they had forgotten to respond. By contrast, older adults displayed this bias much less frequently. Elaborated responding to cues had the effect of improving the performance of younger, but not older adults.

METHODS: Alternative symbols identified as most successful in an earlier study were further refined through the use of multiple focus groups and expert review. Six symbols emerged as potential candidates to replace the current symbol. A nationally distributed field trial (n = 700) examined these six alternate teratogen warnings in addition to the symbol presently in use. RESULTS: Five of the alternate warning symbols exceeded the level of correct interpretation elicited by the current symbol. No symbol exceeded the ANSI limit of 5% critical confusion. Two symbols consistently elicited the most accurate responses in terms of message interpretation, target audience, intended action, and perceived consequences of ignoring the warning. CONCLUSIONS: This effort produced at least two viable alternative symbols that appear to be more effective than the current symbol at communicating both the instruction to not take while pregnant and the consequence that exposure could cause birth defects. Several results varied by participant characteristics. Understanding how members of diverse subpopulations might interact with these warnings should be informative to healthcare professionals.

A total of 330 individuals participated; 72% owned a cellular phone. The results indicate that nonusers of cellular phones believed more strongly than users that cellular phone use while driving negatively affects driving performance and that talking on the cellular phone could potentially cause an accident, and they also had a greater preference for new laws limiting such acts. Cellular phone users, more than nonusers, preferred no laws limiting cellular phone use and believed more strongly that other people driving while using a cellular phone were more dangerous than themselves doing the same.

We apply a systems approach to help bridge this gap between research and practice to address the disparity between what older adults would like to learn and the content of computer training courses. We review the literature on training older adults to use computers and report data from a set of structured interviews to illustrate the criticality of each step in the systems approach. Lastly, we provide the means to evaluate existing computer training programs and suggest modifications for improvement.

Framing decision options as either gains or losses is a common method of altering decision-making behavior. In the experiment reported here, benchmark decision-making data collected in the 1970s by Tversky and Kahneman (1981, 1988) were compared with data collected from current samples of young and older adults to determine whether behavior was consistent across time. Although differences did emerge between the benchmark and the present samples, the effect of framing on decision behavior was relatively stable. The present findings suggest that adults of all ages are susceptible to framing effects. Results also indicated that apparent age differences might be better explained by an analysis of cohort and time-of-testing effects.
