Item The Advancing Understanding of Transportation Options (AUTO) study: design and methods of a multi-center study of decision aid for older drivers(BMC, 2021-05-03) Betz, Marian E.; Omeragic, Faris; Meador, Lauren; DiGuiseppi, Carolyn G.; Fowler, Nicole R.; Han, S. Duke; Hill, Linda; Johnson, Rachel L.; Knoepke, Christopher E.; Matlock, Daniel D.; Moran, Ryan; Medicine, School of MedicineBackground: Decision-making about when to stop driving for older adults involves assessment of driving risk, availability of support or resources, and strong emotions about loss of independence. Although the risk of being involved in a fatal crash increases with age, driving cessation can negatively impact an older adult's health and well-being. Decision aids can enhance the decision-making process by increasing knowledge of the risks and benefits of driving cessation and improve decision quality. The impact of decision aids regarding driving cessation for older adults is unknown. Methods: The Advancing Understanding of Transportation Options (AUTO) study is a multi-site, two-armed randomized controlled trial that will test the impact of a decision aid on older adults' decisions about changes in driving behaviors and cessation. AUTO will enroll 300 drivers age ≥ 70 years with a study partner (identified by each driver); the dyads will be randomized into two groups (n = 150/group). The decision aid group will view the web-based decision aid created by Healthwise at baseline and the control group will review information about driving that does not include evidence-based elements on risks and benefits and values clarification about driving decisions. The AUTO trial will compare the effect of the decision aid, versus control, on a) immediate decision quality (measured by the Decisional Conflict Scale; primary outcome); b) longitudinal psychosocial outcomes at 12 and 24 months (secondary outcomes); and c) longitudinal driving behaviors (including reduction or cessation) at 12 and 24 months (secondary outcomes). Planned stratified analyses will examine the effects in subgroups defined by cognitive function, decisional capacity, and readiness to stop driving. Discussion: The AUTO study is the first large-scale randomized trial of a driving decision aid for older adults. Results from this study will directly inform clinical practice about how best to support older adults in decision-making about driving.Item Diagnosing Dyspneic Older Adult Emergency Department Patients Pilot Study: Diagnoses and Potential Role of Antimicrobial Peptides(Wiley, 2021) Hunold, Katherine M.; Schwaderer, Andrew L.; Exline, Matthew; Hebert, Courtney; Lampert, Brent C.; Southerland, Lauren T.; Stephens, Julie A.; Bischof, Jason J.; Caterino, Jeffrey M.; Pediatrics, School of MedicineStudy Objectives: Pneumonia, chronic obstructive pulmonary disease (COPD), and heart failure (HF) exacerbations can present similarly in the older adult in the Emergency Department (ED), leading to sub-optimal treatment from over- and under-diagnosis. There may be a role for antimicrobial peptides (AMPs) in improving the accurate diagnosis of pneumonia in these patients. Methods: This pilot was a prospective, observational cohort study of older adults (aged ≥65 years of age) who presented to the ED with dyspnea or elevated respiratory rate. To identify biomarkers of pneumonia, serum levels of white blood cell count, procalcitonin (PCT), and antimicrobial peptides (human beta defensin 1 and 2 [HBD-1, -2], human neutrophil peptides 1–3 [HNP1–3] and cathelididin [LL-37]) were compared between those with and without pneumonia. Criterion standard reviewers retrospectively determined the diagnoses present in the ED. Results: Three hundred ninety-one patients were screened, 140 were eligible, and 79 were enrolled. Based on criterion standard review, pneumonia was present in 10 (12.7%), COPD in 9 (11.4%) and HF in 31 (39.2%) with a co-diagnosis rate of 10.1% by criterion standard review. Comparatively, emergency medicine attending physicians diagnosed pneumonia in 16 (20.3%), COPD in 12 (15.2%), and HF in 30 (38.0%) with co-diagnosis rate of 15.2%. Emergency physicians agreed with criterion standard diagnoses in 90% of pneumonia, 75% of COPD and 65% of HF diagnoses. Differences in leukocyte count (p<0.01) and two novel AMPs (DEFA5 (p=0.08) and DEFB2 (p=0.09)) showed promise for diagnosing pneumonia. Conclusions: Emergency physicians continue to have poor diagnostic accuracy in dyspneic older adult patients. Serum AMP levels are one potential tool to improve diagnostic accuracy and outcomes for this important population and require further study.Item Inmates Care: Computer-Based Training for Geriatric and End-of-Life Care in Prisons(Mary Ann Liebert, 2021) Loeb, Susan J.; Murphy, Julie L.; Kitt-Lewis, Erin; Wion, Rachel K.; Jerrod, Tiffany; Myers, Valerie H.; School of NursingThe growing aged and dying incarcerated population increases demands on corrections health care. People who are incarcerated can assist in care delivery; however, currently, their training is typically face-to-face, home grown, and variable in content and duration. Six focus groups conducted with peer caregivers (PCs) (n = 12) and staff (n = 15) identified priority training topics. Three prototype modules (Standard Precautions; Loss and Grief; and Role of the Inmate Caregiver in the Final Hours) were developed in consultation with an advisory board. Face-to-face usability testing with (n = 20) PCs and staff confirmed contextual relevance and feasibility of the Inmates Care training. The mean system usability score for all participant segments was 86.5. Inmates Care holds promise to complement nurse-led training with a standardized e-training package.Item “Is it time to stop driving?”: A Randomized Clinical Trial of an Online Decision Aid for Older Drivers(Wiley, 2022) Betz, Marian E.; Hill, Linda L.; Fowler, Nicole R.; DiGuiseppi, Carolyn; Han, S. Duke; Johnson, Rachel L.; Meador, Lauren; Omeragic, Faris; Peterson, Ryan A.; Matlock, Daniel D.; Medicine, School of MedicineBackground: Many older adults face the difficult decision of when to stop driving. We sought to test whether an online driving decision aid (DDA) would improve decision quality. Methods: This prospective two-arm randomized trial enrolled English-speaking licensed drivers (age ≥70 years) without significant cognitive impairment but with ≥1 diagnosis associated with increased likelihood of driving cessation); all participants received primary care in clinics associated with study sites in three states. The intervention was the online Healthwise® DDA for older adults addressing “Is it time to stop driving?”; control was web-based information for older drivers only. The primary outcome was decision conflict as estimated by the Decisional Conflict Scale (DCS; lower scores indicate higher quality). Secondary outcomes were knowledge and decision self-efficacy about driving decisions. We examined post-randomization differences in primary and secondary outcomes by study arm using generalized linear mixed-effects models with adjustment for site and pre-randomization scores. Results: Among 301 participants (mean age: 77.1 years), 51.2% identified as female and the majority as non-Hispanic (99.0%) and White (95.3%); 98.0% lived in an urban area. Participant characteristics were similar by study arm but differed across sites. Intervention participants had a lower mean DCS score (12.3 DDA vs 15.2 control; adjusted mean ratio [AMR] 0.76, 95%CI 0.61–0.95; p=0.017). Intervention participants had higher mean knowledge scores (88.9 DDA vs 79.9 control; OR 1.13, 95%CI 1.01–1.27, p=0.038); there was no difference between groups in self-efficacy scores. The DDA had high acceptability; 86.9% of those who viewed it said they would recommend it to others in similar situations. Conclusions: The online Healthwise® DDA decreased decision conflict and increased knowledge in this sample of English-speaking, older adults without significant cognitive impairment, although most chose to continue driving. Use of such resources in clinical or community settings may support older adults as they transition from driving to other forms of mobility.Item The Moderate Alcohol and Cardiovascular Health Trial (MACH15): Design and methods for a randomized trial of moderate alcohol consumption and cardiometabolic risk(Oxford University Press, 2020-12) Spiegelman, Donna; Lovato, Laura C.; Khudyakov, Polyna; Wilkens, Trine L.; Adebamowo, Clement A.; Adebamowo, Sally N.; Appel, Lawrence J.; Beulens, Joline W.J.; Coughlin, Janelle W.; Dragsted, Lars Ove; Edenberg, Howard J.; Eriksen, Jane N.; Estruch, Ramon; Grobbee, Diederick E.; Gulayin, Pablo E.; Irazola, Vilma; Krystal, John H.; Lazo, Mariana; Murray, Margaret M.; Rimm, Eric B.; Schrieks, Ilse C.; Williamson, Jeff D.; Mukamal, Kenneth J.; Biochemistry and Molecular Biology, School of MedicineBackground: Observational studies have documented lower risks of coronary heart disease and diabetes among moderate alcohol consumers relative to abstainers, but only a randomized clinical trial can provide conclusive evidence for or against these associations. Aim: The purpose of this study was to describe the rationale and design of the Moderate Alcohol and Cardiovascular Health Trial, aimed to assess the cardiometabolic effects of one alcoholic drink daily over an average of six years among adults 50 years or older. Methods: This multicenter, parallel-arm randomized trial was designed to compare the effects of one standard serving (∼11-15 g) daily of a preferred alcoholic beverage to abstention. The trial aimed to enroll 7800 people at high risk of cardiovascular disease. The primary composite endpoint comprised time to the first occurrence of non-fatal myocardial infarction, non-fatal ischemic stroke, hospitalized angina, coronary/carotid revascularization, or total mortality. The trial was designed to provide >80% power to detect a 15% reduction in the risk of the primary outcome. Secondary outcomes included diabetes. Adverse effects of special interest included injuries, congestive heart failure, alcohol use disorders, and cancer. Results: We describe the design, governance, masking issues, and data handling. In three months of field center activity until termination by the funder, the trial randomized 32 participants, successfully screened another 70, and identified ∼400 additional interested individuals. Conclusions: We describe a feasible design for a long-term randomized trial of moderate alcohol consumption. Such a study will provide the highest level of evidence for the effects of moderate alcohol consumption on cardiovascular disease and diabetes, and will directly inform clinical and public health guidelines.Item Race and Gender-Based Perceptions of Older Septuagenarian Adults(Mary Ann Liebert, 2022-11-14) Melton, Forest; Palmer, Kelly; Solola, Sade; Luy, Luis; Herrera-Theut, Kathryn; Zabala, Leanne; Knapp, Shannon M.; Yee, Ryan; Yee, Erika; Calhoun, Elizabeth; Thomas Hebdon, Megan C.; Pool, Natalie; Sweitzer, Nancy; Breathett, Khadijah; Medicine, School of MedicineObjectives: Older adults face racism, sexism, and ageism. As the U.S. population ages, it is important to understand how the current population views older adults. Methods: Participants recruited through Amazon's Mechanical Turk provided perceptions of older Black and White models' photographs. Using mixed-effect models, we assessed interactions between race and gender of participants and models. Results: Among Participants of Color and White participants (n = 712, 70% non-Hispanic White, 70% women, mean 37.81 years), Black models were perceived as more attractive, less threatening, and sadder than White models, but differences were greater for White participants (race-by-race interaction: attractive p = 0.003, threatening p = 0.009, sad p = 0.016). Each gender perceived their respective gender as more attractive (gender-by-gender interaction p < 0.0001). Male and female participants perceived male models as happier than female models, but differences were greater for male participants (p = 0.026). Irrespective of participant age group, women were perceived as more threatening (p = 0.012). Other perceptions were not significant. Discussion: Participants had few biases toward older Black and White models, while gender biases favored men.
