Abstract

COVID-19 vaccination and regular testing of nursing home staff have been critical interventions for mitigating COVID-19 outbreaks in US nursing homes. Although implementation of testing has largely been left to nursing home organizations to coordinate, vaccination occurred through a combination of state, federal, and organization efforts. Little research has focused on structural variation in these processes. We examined whether one structural factor, the primary shift worked by staff, was associated with differences in COVID-19 testing rates and odds of vaccination, using staff-level data from a multistate sample of 294 nursing homes. In facility fixed effects analyses, we found that night-shift staff had the lowest testing rates and lowest odds of vaccination, whereas day-shift staff had the highest testing rates and odds of vaccination. These findings highlight the need to coordinate resources and communication evenly across shifts when implementing large-scale processes in nursing homes and other organizations with shift-based workforces.

7. Using Stories to Enhance and Simplify Computer Simulations for Teaching

Author

Feifer, Richard G. and Hinrichs, Thomas R.

Abstract

Computer-based simulations are a valuable teaching tool because they permit a learner to explore a phenomenon on his o w n and to learn from his mistakes. T w o factors, however, limit the use of computer simulations in teaching: good simulations are hard to build and learners can flounder with just a simulation. W e have built HeRMiT^, a case-based tutor that integrates a simulation with a library of videotaped stories. The stories make up for any lack of depth or fidelity in the simulation by facilitating the generalization and application of underlying principles.

Author

Feifer, Richard G. and Tazbaz, Denise

Abstract

Good human-computer interfaces are essential in multimedia. Discusses methods of organizing information: non-linear versus linear, interactive, meaningful choices, and chunking; principles of interface design: knowing the users and offering options that are distinct, non-ambiguous, from user point of view, and in user terms; and interface approaches: cockpit, organized cockpit, hierarchical, multiple view, and search field.

17. COVID-19 Mortality Rates Among Nursing Home Residents Declined From March To November 2020

Abstract

Improved therapeutics and supportive care in hospitals have helped reduce mortality from COVID-19. However, there is limited evidence as to whether nursing home residents, who account for a disproportionate share of COVID-19 deaths and are often managed conservatively in the nursing home instead of being admitted to the hospital, have experienced similar mortality reductions. In this study we examined changes in thirty-day mortality rates between March and November 2020 among 12,271 nursing home residents with COVID-19. We found that adjusted mortality rates significantly declined from a high of 20.9 percent in early April to 11.2 percent in early November. Mortality risk declined for residents with both symptomatic and asymptomatic infections and for residents with both high and low clinical complexity. The mechanisms driving these trends are not entirely understood, but they may include improved clinical management within nursing homes, improved personal protective equipment supply and use, and genetic changes in the virus.

Abstract

Background: At the height of the COVID‐19 pandemic, a large nursing home chain implemented a policy to temporarily hold potentially unnecessary medications. We describe rates of held and discontinued medications after a temporary hold policy of potentially unnecessary or nonessential medications. Methods: This retrospective cohort study uses electronic health record (EHR) data on 3247 residents of 64 nursing homes operated by a multistate long‐term care provider. Medications were documented in the electronic medication administration record. Overall medication held and discontinued incidences are reported. Hierarchical Bayesian modeling is used to determine individual probabilities for medication discontinuation within each facility. Results: In total, 3247 residents had 5297 nonessential medications held. Multivitamins were most likely to be held, followed by histamine‐2 receptor antagonists, antihistamines, and statins. At the end of the hold policy, 2897 of 5297 (54%) were permanently discontinued, including probiotics (73%), histamine‐2 receptor antagonists (66%), antihistamines (64%), and statins (45%). Demographics, cognitive and functional impairment were similar between residents with medications who were discontinued versus continued. For most medications, more than 50% of the variance in whether medications were discontinued was explained by facility rather than resident‐level factors. Conclusion: A temporary medication hold policy implemented during the CoVID‐19 pandemic led to the deprescribing of a plurality of 'nonessential' medications. This type of organization‐wide initiative may be an effective mechanism for altering future prescribing behaviors to reduce the use of unnecessary medications. [ABSTRACT FROM AUTHOR]

32. An Intelligent Tutoring System Approach to Teaching People How to Learn

Author

Feifer, Richard G.

Abstract

Sherlock is an intelligent tutoring system designed to teach people to build simplified knowledge representations (graphic maps) to facilitate learning of a text. Previous attempts to automate instruction in graphic mapping have had problems because they attempted to diagnose a learner's misunderstandings by looking at a finished graphic map. Sherlock uses a knowledge-based approach to diagnose a leamer's misunderstandings by looking at the knowledge and processes that lead to a learner's graphic map, rather than the completed map. In Sherlock's model a semantic network is used to represent the knowledge in the text. A production system models the strategy for constructing a gniphic map by initiating spreading activation on the semantic network, and interpreting the resulting activation patterns. In a limited evaluation Sherlock was able to correcdy determine if a construction was appropriate 9 6 % of the time.

44. What's so Hard about Understanding Language

Author

CALIFORNIA UNIV LOS ANGELES, Read, Walter, Dyer, Michael, Feifer, Richard, CALIFORNIA UNIV LOS ANGELES, Read, Walter, Dyer, Michael, and Feifer, Richard

Abstract

This paper reports empirical work in artificial intelligence (AI) on natural language processing. The kind of AI that we are interested in is cognitive modeling. The goal is to describe some aspect of human mental activity, say problem solving or language use, in computational terms. The central issues is this kind of study turn out to be representation and reasoning (corresponding roughly to data structures and control in computer programs. In this paper we examine several problems in language understanding involving semantic ambiguity, anaphoric reference, and metonymy.
