Study protocol for "In-vehicle sensors to detect changes in cognition of older drivers".

BACKGROUND: Driving is a complex behavior that may be affected by early changes in the cognition of older individuals. Early changes in driving behavior may include driving more slowly, making fewer and shorter trips, and errors related to inadequate anticipation of situations. Sensor systems installed in older drivers' vehicles may detect these changes and may generate early warnings of possible changes in cognition. METHOD: A naturalistic longitudinal design is employed to obtain continuous information on driving behavior that will be compared with the results of extensive cognitive testing conducted every 3 months for 3 years. A driver facing camera, forward facing camera, and telematics unit are installed in the vehicle and data downloaded every 3 months when the cognitive tests are administered. RESULTS: Data processing and analysis will proceed through a series of steps including data normalization, adding information on external factors (weather, traffic conditions), and identifying critical features (variables). Traditional prediction modeling results will be compared with Recurring Neural Network (RNN) approach to produce Driver Behavior Indices (DBIs), and algorithms to classify drivers within age, gender, ethnic group membership, and other potential group characteristics. CONCLUSION: It is well established that individuals with progressive dementias are eventually unable to drive safely, yet many remain unaware of their cognitive decrements. Current screening and evaluation services can test only a small number of individuals with cognitive concerns, missing many who need to know if they require treatment. Given the increasing number of sensors being installed in passenger vehicles and pick-up trucks and their increasing acceptability, reconfigured in-vehicle sensing systems could provide widespread, low-cost early warnings of cognitive decline to the large number of older drivers on the road in the U.S. The proposed testing and evaluation of a readily and rapidly available, unobtrusive in-vehicle sensing system could provide the first step toward future widespread, low-cost early warnings of cognitive change for this large number of older drivers in the U.S. and elsewhere.

Cannabinoids and synthetic cannabinoids as a cause of death: Trends and their healthcare implications.

INTRODUCTION: Cannabis remains one of the most widely used illicit substances globally, with 188 million users in 2017. In the United States, nearly 50 million people are reported to have used cannabis in 2020. More research is needed because of the dramatic increase in cannabis use and the perception that its use has minimal risk. DESIGN: The researchers used a retrospective design for this study. METHODS: We used the Florida Department of Law Enforcement data from 2014 to 2020 for this study. We used descriptive statistics to report the characteristics of decedents whose cause of death (COD) was associated with cannabinoid (CB) and synthetic cannabinoid (SC) use. We used a general linear model with repeated measures to examine CB and SC death rate trends. RESULTS: A total of 386 decedents' COD in Florida was associated with CB and SC use. Nearly 28% of decedents were 45-54 years, male (87.8%), and non-Hispanic whites (65.3%). One hundred percent of CB-related decedents died in urban counties. In rural counties, SC decedents accounted for 28.3% of deaths. Of decedents in rural counties, 39.9% were African American. Most decedents (with CB and SC use) died from accidents (98.7%), with 12.6% of cases involving cardiovascular-related illnesses. CONCLUSION: CBs and SCs as a COD pose a legitimate health problem to society. More people ages 45-54 died from CBs and SCs. Drug intoxications (from CBs and SCs) and motor vehicle collisions accounted for most of the accidents reported while under the influence of CBs and SCs. While most decedents from both CBs and SCs were non-Hispanic whites, a substantial proportion of African Americans died from SCs as a COD in rural counties. It is important that the public become aware of the risks for adverse effects of CB and SC. The public needs to be aware that CB and SC use can exacerbate cardiac-related conditions. CLINICAL RELEVANCE: This study has clinical relevance to patient safety. CB and SC use contributes to motor vehicle accidents and can cause adverse effects including death.

Use of Sensors for Fall Prediction in Older Persons: A Scoping Review.

The application of technological advances and clear articulation of how they improve patient outcomes are not always well described in the literature. Our research team investigated the numerous ways to measure conditions and behaviors that precede patient events and could signal an important change in health through a scoping review. We searched for evidence of technology use in fall prediction in the population of older adults in any setting. The research question was described in the population-concept-context format: "What types of sensors are being used in the prediction of falls in older persons?" The purpose was to examine the numerous ways to obtain continuous measurement of conditions and behaviors that precede falls. This area of interest may be termed emerging knowledge . Implications for research include increased attention to human-centered design, need for robust research trials that clearly articulate study design and outcomes, larger sample sizes and randomization of subjects, consistent oversight of institutional review board processes, and elucidation of the human costs and benefits to health and science.

Nursing Home Resident, Family, and Staff Perspectives on Hospital Transfers for End-of-Life Care.

Residents who are terminally ill often experience transfers to the emergency department resulting in hospitalizations, which may be potentially avoidable with treatment in the nursing home. This qualitative study explored the perspectives of 15 residents, 10 family members, and 20 nursing home staff regarding end-of-life care and the circumstances prompting resident transfers. Data analysis of participant interviews conducted January to May 2019 in a South Florida nursing home identified four themes related to transfer to the hospital: time left to live, when aggressive treatments would be unavailing, not knowing what the nursing home can do, and transfer decisions are situation-dependent. Study findings underscore the importance of increasing resident and family awareness of treatments available in the nursing home and person-centered advance care planning discussions. Further research should explore the reasons for residents' and family members' choice of aggressive therapies and their goals for care at the end of life.

Chief Nursing Officer Perspectives on Nursing Theory-Guided Practice.

OBJECTIVE: The purpose of this study was to identify what guides nursing practice. BACKGROUND: Change occurred when the Magnet Recognition Program® no longer required a nursing theory. METHODS: This was a mixed-methods study to identify the process used to implement nursing theory-guided practice and the relationship to professional practice recognition. Deidentified quantitative data were collected from 36 chief nursing officers (CNOs). Seventeen CNOs participated in the qualitative interview. RESULTS: Thirteen CNOs were from a Magnet®-designated facility. Ten CNOs were on the Magnet journey, and 2 had no intent to seek Magnet recognition. Two CNOs were from a Pathway to Excellence®-designated facility. One CNO was on the Pathway to Excellence journey. The majority of respondents who were Magnet® recognized who participated in the survey used Watson's Theory of Human Caring. Themes were identified that share the benefits and strategies to integrate nursing-guided theory into nursing processes, structures, and outcomes. CONCLUSION: Findings will benefit CNOs as they make decisions related to pursuing Magnet status recognition.

An updated measure for investigating basic knowledge of Alzheimer's disease in underserved rural settings.

Objective: Older rural adults face a higher burden of Alzheimer's disease (AD) and delayed detection. This risk is heightened in rural populations that are ethnically diverse. Patients and providers are often hesitant to participate in screening, partially due to gaps in knowledge of the current science. The purpose of this paper is to describe the results of administering the revised version of the Basic Knowledge of Alzheimer's Disease (BKAD) measure in small rural communities in five different states.Methods: The BKAD measure was revised after first being tested in rural Appalachia. Revisions including eliminating non-discriminating items and adding questions regarding early detection, sleep, head injury, and vision changes. Reliability and validity testing included Cronbach's alpha and Rasch item analysis, test-retest, and predictive validity. Descriptive measures and independent sample t-tests were used to analyze knowledge gaps and sociodemographics.Results: Tests for reliability and validity were highly favorable, including Cronbach's alpha = .85 and overall Rasch item analysis of .94. Three-fourths of participants knew that annual cognitive screening was recommended for older adults, but only one-fourth had been previously screened. Sociodemographic findings revealed that a majority of participants (86%) would participate in annual memory screening if offered, regardless of education or health literacy level.Conclusion: The BKAD measure is a good fit for use in rural and underserved populations. BKAD results can inform the design of culturally relevant programs for raising awareness of the importance of early AD detection and treatment.

Changes on Walking During Street Crossing Situations and on Dorsiflexion Strength of Older Caribbean Americans After an Exercise Program: A Pilot Study.

The objective of this pilot study was to evaluate a 6-month exercise program completed by 10 older Caribbean Americans. Assessments were done at baseline and 3 and 6 months, and included walks on an instrumented mat at preferred speed, and during street crossing simulations with regular (10 s) and reduced time (5 s). There were no significant differences on preferred walking speed over time. Differences between the street crossing conditions were found only at 6 months. Significant changes over time among the assessments were found only during street crossing with reduced time. Street crossing with reduced time was the only walking condition sensitive to capture changes associated with participating in the exercise program. There was a significant increase in dorsiflexion strength overtime. At 6 months it was significantly higher than at baseline and 3 months. The program was feasible, acceptable, and had some positive effects on walking, knee flexion, and dorsiflexion strength.

Evaluation of a Novel Communication Application From Nurses' Perspectives.

The purpose of this article is to report usability of a computer application, Speak for Myself, from nurses' perspectives. This was a one-group exploratory survey. Nurses included patients in the study who were older than 18 years, could write and speak English, were unable to verbalize needs for any reason, and had a specified sedation-agitation scale (-1 to +1). Patients were excluded if they were younger than 18, could not write and/or speak English, or had a Richmond Agitation-Sedation Scale score exceeding -1 to +1. Twelve RNs from various ICUs in two hospitals in South Florida participated in the study. A person who was a supervisor or clinical specialist was chosen in each participating unit and at each hospital for recruitment of patient participants. Five nurses (41.6%) stated their patients were able to communicate better with the use of Speak for Myself, and all 12 nurses (100%) indicated they would use Speak for Myself again. Suggestions for further development of Speak for Myself were offered from the nurses. Limitations include a small sample in South Florida. The results of this and previous studies about Speak for Myself will be used in further development and testing of the computer application.

Barriers and Facilitators to Implementing a Change Initiative in Long-Term Care Using the INTERACT® Quality Improvement Program.

Implementation of major organizational change initiatives presents a challenge for long-term care leadership. Implementation of the INTERACT® (Interventions to Reduce Acute Care Transfers) quality improvement program, designed to improve the management of acute changes in condition and reduce unnecessary emergency department visits and hospitalizations of nursing home residents, serves as an example to illustrate the facilitators and barriers to major change in long-term care. As part of a larger study of the impact of INTERACT® on rates of emergency department visits and hospitalizations, staff of 71 nursing homes were called monthly to follow-up on their progress and discuss successful facilitating strategies and any challenges and barriers they encountered during the yearlong implementation period. Themes related to barriers and facilitators were identified. Six major barriers to implementation were identified: the magnitude and complexity of the change (35%), instability of facility leadership (27%), competing demands (40%), stakeholder resistance (49%), scarce resources (86%), and technical problems (31%). Six facilitating strategies were also reported: organization-wide involvement (68%), leadership support (41%), use of administrative authority (14%), adequate training (66%), persistence and oversight on the part of the champion (73%), and unfolding positive results (14%). Successful introduction of a complex change such as the INTERACT® quality improvement program in a long-term care facility requires attention to the facilitators and barriers identified in this report from those at the frontline.

Communication Needs of Critical Care Patients Who Are Voiceless.

Voice is crucial for communication in all healthcare settings. Evidence-based care highlights the need for clear communication. Clear communication methods must be applied when caring for special populations in order to assess pain effectively. Communication efforts also should be offered to patients who are in end-of-life care and would like to make independent decisions. A computer communication application was offered to patients in intensive care/critical care units in three hospitals in South Florida. Inclusion criteria included the age of 18 years or older, Richmond Agitation Sedation Scale between -1 and +1, ability to read and write English, and willingness to use the computer application. Exclusion criteria included inability to read and write English, agitation as defined by the Richmond Agitation Sedation Scale, and any patient on infection isolation protocol. Four qualitative themes were revealed, which directly relate to two published evidence-based guidelines. These are the End of Life Care and Decision Making Evidence-Based Care Guidelines and the Pain Assessment in Special Populations Guidelines. This knowledge is important for developing effective patient-healthcare provider communication.

Stress in Persons with Dementia: Benefits of a Memory Center Day Program.

Most persons with dementia are cared for by family members who are so overwhelmed that their mental and physical health declines. Adult day care programs (ADC) are growing in number to meet caregivers' needs for respite but little is known about their effect on enrollee mental health. We examined mental health of enrollees (stress, anxiety, mood, emotions) and arousal (blood pressure and salivary cortisol) from day program enrollment to 3 months following enrollment. Results showed significant decreases in morning cortisol level at 1 and 3 months (p=.047). Perceived stress decreased at 1 and 3 months measured by Perceived Stress Scale (p=.03) and Index of Clinical Stress (p=.01). Results provide support for ADC as a stress-reducing environment for individuals with mild to moderate cognitive impairment. Future studies should be conducted to examine which elements of ADC are beneficial.

They Know Me Here: Patients' Perspectives on Their Nursing Home Experiences

Perspectives from patients who reside in nursing homes can inform administrators and providers about the patient experience in long-term care. In a study of preferences for care in the nursing home or hospital should an acute change in condition occur, nursing home residents offered spontaneous descriptions of their experiences in the nursing home and during their prior hospital stays. This article offers background information about nursing home reform and standards, and contemporary reports on the patient experience in nursing homes. Methods, results, and discussion of the study findings will inform readers specifically about the analysis of the narrative data as it relates to the patient experience. Positive and negative aspects of nursing home patient experiences are discussed and compared to hospital patient experiences. Both settings were both praised and strongly criticized. Many concerns identified as patients discussed their experiences can be remedied by the owners and administrators of these facilities.

Health-Related Quality of Life and Pain Intensity Among Ethnically Diverse Community-Dwelling Older Adults.

Chronic pain is highly prevalent in older adults and often negatively associated with health-related quality of life (HRQoL). This study compared HRQoL, including physical health and mental health, in persons of differing ethnicities, and identified factors associated with pain intensity and HRQoL in ethnically diverse older adults. Older adults with chronic pain from four ethnic groups (African Americans, Afro-Caribbeans, Hispanics, and European Americans) were recruited from the Florida Atlantic University Healthy Aging Research Initiative (HARI) registry. The Medical Outcomes Study Short Form-36 (SF-36) was used to evaluate HRQoL, including functional status, emotional well-being, and social functioning. Of 593 persons in the four ethnic groups in the registry, 174 met the inclusion criteria (pain level of four or higher on an 11-point scale, lasting 3 months or longer). Among these 174, African Americans reported the highest level of pain intensity, followed by Afro-Caribbeans, Hispanics, and European Americans. Hispanics reported the highest physical health scores and the lowest mental health scores. In contrast, African Americans reported the highest mental health scores and the lowest physical health scores. Multivariate linear regression analysis revealed that ethnicity, lower physical health scores, and lower mental health scores were significantly (p ≤ .01) associated with pain intensity. Understanding ethnic variations in response to pain intensity may address gaps in knowledge about HRQoL to reduce disparities in optimal care. Health care providers should consider ethnic norms and cultural diversity to provide optimal interventions for this population.

Evaluation of Speak for Myself with Patients Who Are Voiceless.

PURPOSE: To describe the creation and initial feasibility study of a new computer application to improve communication with people who cannot communicate by customary means during their hospitalization. DESIGN: This was a mixed-methods, quasi-experimental design. METHODS: This exploratory feasibility study obtained data about the experiences of 20 intensive care patients in three South Florida hospitals who were unable to speak due to mechanical obstruction. FINDINGS: Study participants (20), who ranged in age from 45 to 91 years (M=67.4, SD=12.88) and between -1 to +1 (SD=-0.15) on the Richmond Agitation Sedation Scale, used Speak for Myself from 4 to 16 hours with a mean of 8.86 (SD=2.12). Ninety-five percent of the participants stated that Speak for Myself was helpful for communication. CONCLUSIONS: Speak for Myself was helpful to patients who used it. This was a small study (n=20). It warrants further investigation. CLINICAL RELEVANCE: Patients who are unable to communicate their needs through conventional methods still want to make their preferences and needs known. Speak for Myself is a new application that facilitates ensuring the patient's voice is heard.

Costs associated with recruitment and interviewing of study participants in a diverse population of community-dwelling older adults.

BACKGROUND: America's racial and ethnic composition is changing so rapidly that minority groups are expected to constitute almost half of the U.S. population by 2060. Special efforts are needed to effectively recruit and retain members of racial and ethnic minority groups in health-related research studies, but the information available on time and costs associated with their recruitment is limited. OBJECTIVES: The aim of this study was to describe and compare the time and monetary costs associated with recruiting and interviewing a diverse sample of older adults living in south Florida. METHODS: Men and women aged 60 years and older from four ethnic groups-African American, Afro-Caribbean, Hispanic American, and European American-were recruited to participate in a longitudinal study of healthy aging. Costs for study activities (including recruitment, scheduling sessions, interviewing, file scoring, log updating, blood specimen analysis and storage, data analysis, and monetary compensation to participants) were determined after 100 weeks of data collection. RESULTS: Altogether, 483 participants completed the study in the first 100 weeks. The total cost for each participant ranged from $265 to $576. Each successful enrollment required an average of 1.83 hours for recruitment and scheduling of the interviews. The time to interview African American and Afro-Caribbeans was greater than the time needed to interview Hispanic American and European American participants. DISCUSSION: To develop more accurate budgets for recruitment of minority individuals into research studies and to use the limited resources in an effective way, careful planning and ongoing monitoring of costs are essential.

Older Hispanics' explanatory model of depression.

Cultural variations in the perception of depression make it difficult to recognize the disorder resulting in older Hispanics not being diagnosed and not receiving appropriate treatment. This study used a mixed-method design to explore older Hispanics' explanatory model of depression. Depression was recognized as the result of life stressors and personal weaknesses. Terms used for depressed people included "crazy, worry, bored, and nerves." These culturally coded terms may confound diagnosis among many Hispanics who find depression a shameful condition. Findings can be used to inform the adaptation of culturally relevant approaches to better serve the Hispanic community in this country.

Remaining in the nursing home versus transfer to acute care: resident, family, and staff preferences.

Resident and family insistence on transfer is a major factor in the occurrence of potentially avoidable transfers from nursing homes (NHs) to acute care. The purpose of this study was to explore resident, family, and staff preferences regarding transfer to acute care. A sample of 271 NH residents, family members, staff, and medical providers were interviewed. Seventy-seven percent of residents reported that they had not given any thought to the question of whether they would want to be transferred to acute care. Family members wanted more information than residents, but more residents (39%) thought they should be fully involved in the transfer decision than their family members (12%) or staff (12%). Staff preferred keeping residents in the NH. Families were divided between transferring residents and having them remain in the NH. More residents indicated that their desire to transfer would depend on the severity of their condition and their prognosis. Ethnic group differences were noted. Results suggest that discussion of this issue should occur soon after admission and that differences in perspectives may be expected from those involved.

Multiethnic perspectives on mainstream America.

The terms mainstream America and mainstream American are often used but infrequently defined. The purpose of this study was to explore definitions of these terms among a multiethnic sample of 158 college students. Two major themes emerged from a qualitative analysis: 1) an exclusionary definition as U.S.-born, dominated by Whites and of Judeo-Christian faith versus the predominant, more inclusive, contemporary definition of sharing American values and practices within a diverse society and 2) a contrast between highly critical comments (weakened family ties, moral decay, racism) and favorable comments (opportunity, helpfulness, openness and inclusiveness). Responses by ethnic group were also reported.

Fit2Drive: Screening Older Drivers with Cognitive Concerns.

OBJECTIVES: The purpose of this study was to identify the most parsimonious combination of cognitive tests that accurately predicts the likelihood of passing an on-road driving evaluation in order to develop a screening measure that can be administered as an in-office test. DESIGN: This was a psychometric study of the new test's diagnostic accuracy. SETTINGS AND PARTICIPANTS: The study was conducted at the Florida Atlantic University's Memory Center and Clinical Research Unit, both easily accessible to older drivers. Participants were older drivers who received a driving evaluation at the Memory Center and agreed to have their results included in the Driving Repository and community-based older drivers who volunteered to participate. METHODS: Mini-Mental State Exam (MMSE), Trail Making Tests A and B, Clock Test, Hopkins Verbal Learning Test, and Driving Health Inventory results were compared with an on-road driving evaluation to identify those tests that best predict the ability to pass the on-road evaluation. RESULTS: Altogether, 412 older drivers, 179 men and 233 women, were included in the analysis. Fifty-four percent of Driving Repository participants failed the on-road evaluation compared with 8% of the community sample. The highest correlation to the on-road evaluation was Trails B time in seconds r = -0.713 (P < .001). Variables with high multicollinearity and/or low correlation with the on-road evaluation were eliminated and sets of receiver operating characteristics curves were generated to assess the predictive accuracy of the remaining tests. A linear combination of Trails B in seconds and MMSE using the highest of the Serial 7s or WORLD spelled backward scores accounted for the highest area under the curve of 0.915. Finally, an algorithm was created to rapidly generate the prediction for an individual patient. CONCLUSIONS AND IMPLICATIONS: The Fit2Drive algorithm demonstrated a strong 91.5% predictive accuracy. Usefulness in office-based patient consultations is promising but remains to be rigorously tested.

Interprofessional education in community-based Alzheimer's disease diagnosis and treatment.

As the population ages and understanding of Alzheimer's disease (AD) improves, the number of older adults diagnosed and treated for AD and related dementias is projected to increase. Dementia diagnosis, treatment and patient and family education are complex processes best done through collaboration among healthcare professions. The educational program described in this article aimed to create an interprofessional team approach to the diagnosis and treatment of dementia involving medical and family nurse practitioner students. A two-group treatment/control pretest posttest design was used to measure changes in knowledge, attitudes and appreciation for an interprofessional team approach to patient care. Findings from this interprofessional program demonstrated that nurse practitioner students gained higher levels of knowledge regarding AD, and medical students gained more positive attitudes toward these patients and their caregivers. Comments from students indicated that both medical and nursing students found the experience valuable. Understanding the roles that various providers play will help healthcare professional meet the challenge of caring for the increasing number of patients with memory loss and for their families.
