Item Open Access Accounting for Posttraumatic Stress Disorder Symptom Severity With Pre- and Posttrauma Measures: A Longitudinal Study of Older Adults.(Clin Psychol Sci, 2016-03) Ogle, CM; Rubin, DC; Siegler, ICUsing data from a longitudinal study of community-dwelling older adults, we analyzed the most extensive set of known correlates of PTSD symptoms obtained from a single sample to examine the measures' independent and combined utility in accounting for PTSD symptom severity. Fifteen measures identified as PTSD risk factors in published meta-analyses and 12 theoretically and empirically supported individual difference and health-related measures were included. Individual difference measures assessed after the trauma, including insecure attachment and factors related to the current trauma memory, such as self-rated severity, event centrality, frequency of involuntary recall, and physical reactions to the memory, accounted for symptom severity better than measures of pre-trauma factors. In an analysis restricted to prospective measures assessed before the trauma, the total variance explained decreased from 56% to 16%. Results support a model of PTSD in which characteristics of the current trauma memory promote the development and maintenance of PTSD symptoms.Item Open Access Challenges in the Management of Geriatric Obesity in High Risk Populations.(Nutrients, 2016-05-04) Porter Starr, Kathryn N; McDonald, Shelley R; Weidner, Julia A; Bales, Connie WThe global prevalence of obesity in the older adult population is growing, an increasing concern in both the developed and developing countries of the world. The study of geriatric obesity and its management is a relatively new area of research, especially pertaining to those with elevated health risks. This review characterizes the state of science for this "fat and frail" population and identifies the many gaps in knowledge where future study is urgently needed. In community dwelling older adults, opportunities to improve both body weight and nutritional status are hampered by inadequate programs to identify and treat obesity, but where support programs exist, there are proven benefits. Nutritional status of the hospitalized older adult should be optimized to overcome the stressors of chronic disease, acute illness, and/or surgery. The least restrictive diets tailored to individual preferences while meeting each patient's nutritional needs will facilitate the energy required for mobility, respiratory sufficiency, immunocompentence, and wound healing. Complications of care due to obesity in the nursing home setting, especially in those with advanced physical and mental disabilities, are becoming more ubiquitous; in almost all of these situations, weight stability is advocated, as some evidence links weight loss with increased mortality. High quality interdisciplinary studies in a variety of settings are needed to identify standards of care and effective treatments for the most vulnerable obese older adults.Item Open Access Early Mobility in the Hospital: Lessons Learned from the STRIDE Program.(Geriatrics (Basel, Switzerland), 2018-12) Hastings, Susan Nicole; Choate, Ashley L; Mahanna, Elizabeth P; Floegel, Theresa A; Allen, Kelli D; Van Houtven, Courtney H; Wang, VirginiaImmobility during hospitalization is widely recognized as a contributor to deconditioning, functional loss, and increased need for institutional post-acute care. Several studies have demonstrated that inpatient walking programs can mitigate some of these negative outcomes, yet hospital mobility programs are not widely available in U.S. hospitals. STRIDE (assiSTed eaRly mobIlity for hospitalizeD older vEterans) is a supervised walking program for hospitalized older adults that fills this important gap in clinical care. This paper describes how STRIDE works and how it is being disseminated to other hospitals using the Replicating Effective Programs (REP) framework. Guided by REP, we define core components of the program and areas where the program can be tailored to better fit the needs and local conditions of its new context (hospital). We describe key adaptations made by four hospitals who have implemented the STRIDE program and discuss lessons learned for successful implementation of hospital mobility programs.Item Open Access Prediction models for depression risk among older adults: systematic review and critical appraisal.(Ageing research reviews, 2022-11) Tan, Jie; Ma, Chenxinan; Zhu, Chonglin; Wang, Yin; Zou, Xiaoshuang; Li, Han; Li, Jiarun; He, Yanxuan; Wu, ChenkaiObjective
To provide an overview of prediction models for the risk of major depressive disorder (MDD) among older adults.Methods
We conducted a systematic review combined with a meta-analysis and critical appraisal of published studies on existing geriatric depression risk models.Results
The systematic search screened 23,378 titles and abstracts; 14 studies including 20 prediction models were included. A total of 16 predictors were selected in the final model at least twice. Age, physical health, and cognitive function were the most common predictors. Only one model was externally validated, two models were presented with a complete equation, and five models examined the calibration. We found substantial heterogeneity in predictor and outcome definitions across models; important methodological information was often missing. All models were rated at high or unclear risk of bias, primarily due to methodological limitations. The pooled C-statistics of 12 prediction models was 0.83 (95%CI=0.77-0.89).Conclusion
The usefulness of all models remains unclear due to several methodological limitations. Future studies should focus on methodological quality and external validation of depression risk prediction models.Item Open Access Preoperative Cognitive Impairment As a Predictor of Postoperative Outcomes in a Collaborative Care Model.(J Am Geriatr Soc, 2018-01-13) Zietlow, Kahli; McDonald, Shelley R; Sloane, Richard; Browndyke, Jeffrey; Lagoo-Deenadayalan, Sandhya; Heflin, Mitchell TOBJECTIVES: To compare postoperative outcomes of individuals with and without cognitive impairment enrolled in the Perioperative Optimization of Senior Health (POSH) program at Duke University, a comanagement model involving surgery, anesthesia, and geriatrics. DESIGN: Retrospective analysis of individuals enrolled in a quality improvement program. SETTING: Tertiary academic center. PARTICIPANTS: Older adults undergoing surgery and referred to POSH (N = 157). MEASUREMENTS: Cognitive impairment was defined as a score less than 25 out of 30 (adjusted for education) on the St. Louis University Mental Status (SLUMS) Examination. Median length of stay (LOS), mean number of postoperative complications, rates of postoperative delirium (POD, %), 30-day readmissions (%), and discharge to home (%) were compared using bivariate analysis. RESULTS: Seventy percent of participants met criteria for cognitive impairment (mean SLUMS score 20.3 for those with cognitive impairment and 27.7 for those without). Participants with and without cognitive impairment did not significantly differ in demographic characteristics, number of medications (including anticholinergics and benzodiazepines), or burden of comorbidities. Participants with and without cognitive impairment had similar LOS (P = .99), cumulative number of complications (P = .70), and 30-day readmission (P = .20). POD was more common in those with cognitive impairment (31% vs 24%), but the difference was not significant (P = .34). Participants without cognitive impairment had higher rates of discharge to home (80.4% vs 65.1%, P = .05). CONCLUSION: Older adults with and without cognitive impairment referred to the POSH program fared similarly on most postoperative outcomes. Individuals with cognitive impairment may benefit from perioperative geriatric comanagement. Questions remain regarding the validity of available measures of cognition in the preoperative period.Item Open Access Rapid Transition to Telehealth Group Exercise and Functional Assessments in Response to COVID-19.(Gerontology & geriatric medicine, 2020-01) Jennings, Stephen C; Manning, Kenneth M; Bettger, Janet Prvu; Hall, Katherine M; Pearson, Megan; Mateas, Catalin; Briggs, Brandon C; Oursler, Krisann K; Blanchard, Erin; Lee, Cathy C; Castle, Steven; Valencia, Willy M; Katzel, Leslie I; Giffuni, Jamie; Kopp, Teresa; McDonald, Michelle; Harris, Rebekah; Bean, Jonathan F; Althuis, Katherine; Alexander, Neil B; Padala, Kalpana P; Abbate, Lauren M; Wellington, Toby; Kostra, James; Allsup, Kelly; Forman, Daniel E; Tayade, Arti S; Wesley, Alan D; Holder, Alice; Morey, Miriam CExercise is critical for health maintenance in late life. The COVID-19 shelter in place and social distancing orders resulted in wide-scale interruptions of exercise therapies, placing older adults at risk for the consequences of decreased mobilization. The purpose of this paper is to describe rapid transition of the Gerofit facility-based group exercise program to telehealth delivery. This Gerofit-to-Home (GTH) program continued with group-based synchronous exercise classes that ranged from 1 to 24 Veterans per class and 1 to 9 classes offered per week in the different locations. Three hundred and eight of 1149 (27%) Veterans active in the Gerofit facility-based programs made the transition to the telehealth delivered classes. Participants' physical performance testing continued remotely as scheduled with comparisons between most recent facility-based and remote testing suggesting that participants retained physical function. Detailed protocols for remote physical performance testing and sample exercise routines are described. Translation to remote delivery of exercise programs for older adults could mitigate negative health effects.Item Open Access Sexual risk behaviors and HIV risk among Americans aged 50 years or older: a review.(Subst Abuse Rehabil, 2015) Pilowsky, Daniel J; Wu, Li-TzyAlthough HIV-related sexual risk behaviors have been studied extensively in adolescents and young adults, there is limited information about these behaviors among older Americans, which make up a growing segment of the US population and an understudied population. This review of the literature dealing with sexual behaviors that increase the risk of becoming HIV-infected found a low prevalence of condom use among older adults, even when not in a long-term relationship with a single partner. A seminal study by Schick et al published in 2010 reported that the prevalence of condom use at last intercourse was highest among those aged 50-59 years (24.3%; 95% confidence interval, 15.6-35.8) and declined with age, with a 17.1% prevalence among those aged 60-69 years (17.1%; 95% confidence interval, 7.3-34.2). Studies have shown that older Americans may underestimate their risk of becoming HIV-infected. Substance use also increases the risk for sexual risk behaviors, and studies have indicated that the prevalence of substance use among older adults has increased in the past decade. As is the case with younger adults, the prevalence of HIV infections is elevated among ethnic minorities, drug users (eg, injection drug users), and men who have sex with men. When infected, older adults are likely to be diagnosed with HIV-related medical disorders later in the course of illness compared with their younger counterparts. Physicians are less likely to discuss sexual risk behaviors with older adults and to test them for HIV compared with younger adults. Thus, it is important to educate clinicians about sexual risk behaviors in the older age group and to design preventive interventions specifically designed for older adults.Item Open Access Training and Retraining Older Workers, an Annotated Bibliography.(1965) Kreps, Juanita; Laws, RalphA brief narrative description of the journal article, document, or resource. The need for economy-wide measures designed to retrain workers of all ages resulted in development of this annotated bibliography which is primarily restricted to articles discussing the retraining of older workers. The 123 documents annotated represent the years 1943 through 1964 and are organized under headings of general references and government. (DM)Item Open Access Use of the consolidated framework for implementation research in a mixed methods evaluation of the EQUIPPED medication safety program in four academic health system emergency departments.(Frontiers in health services, 2022-01) Kegler, Michelle C; Rana, Shaheen; Vandenberg, Ann E; Hastings, S Nicole; Hwang, Ula; Eucker, Stephanie A; Vaughan, Camille PBackground
Enhancing Quality of Prescribing Practices for Older Adults Discharged from the Emergency Department (EQUIPPED) is an effective quality improvement program initially designed in the Veterans Administration (VA) health care system to reduce potentially inappropriate medication prescribing for adults aged 65 years and older. This study examined factors that influence implementation of EQUIPPED in EDs from four distinct, non-VA academic health systems using a convergent mixed methods design that operationalized the Consolidated Framework for Implementation Research (CFIR). Fidelity of delivery served as the primary implementation outcome.Materials and methods
Four EDs implemented EQUIPPED sequentially from 2017 to 2021. Using program records, we scored each ED on a 12-point fidelity index calculated by adding the scores (1-3) for each of four components of the EQUIPPED program: provider receipt of didactic education, one-on-one academic detailing, monthly provider feedback reports, and use of order sets. We comparatively analyzed qualitative data from focus groups with each of the four implementation teams (n = 22) and data from CFIR-based surveys of ED providers (108/234, response rate of 46.2%) to identify CFIR constructs that distinguished EDs with higher vs. lower levels of implementation.Results
Overall, three sites demonstrated higher levels of implementation (scoring 8-9 of 12) and one ED exhibited a lower level (scoring 5 of 12). Two constructs distinguished between levels of implementation as measured through both quantitative and qualitative approaches: patient needs and resources, and organizational culture. Implementation climate distinguished level of implementation in the qualitative analysis only. Networks and communication, and leadership engagement distinguished level of implementation in the quantitative analysis only.Discussion
Using CFIR, we demonstrate how a range of factors influence a critical implementation outcome and build an evidence-based approach on how to prime an organizational setting, such as an academic health system ED, for successful implementation.Conclusion
This study provides insights into implementation of evidence-informed programs targeting medication safety in ED settings and serves as a potential model for how to integrate theory-based qualitative and quantitative methods in implementation studies.Item Open Access Using Cost-Effectiveness Analysis in Mixed Methods Research: An Evaluation of an Integrated Care Program for Frequently Hospitalized Older Adults in Singapore(Journal of Mixed Methods Research, 2020-04-01) Penkunas, MJ; Matchar, DB; Wong, CH; Liu, C; Chan, AWMTraditional evaluation techniques are often not suitable for studying health interventions operating in real-world settings, particularly when interventions operate through complex causal pathways. We describe a mixed methods design for evaluating an integrated home care and social support service targeting mature and older adults (55+ years) in Singapore. Here, nurses and community health workers visit patients’ homes to address health and social needs while facilitating linkages to community-based services and providing caregiver support. Our mixed methods evaluation plan is composed of three components: quantitative comparison of hospital-based service utilization, cost-effectiveness analysis, and qualitative investigation into the experiences of patients, caregivers, and individuals who declined services. This article contributes a description of how cost-effectiveness analysis adds value when incorporated into mixed methods studies.Item Open Access Walking All over COVID-19: The Rapid Development of STRIDE in Your Room, an Innovative Approach to Enhance a Hospital-Based Walking Program during the Pandemic.(Geriatrics (Basel, Switzerland), 2021-11) Hughes, Jaime M; Bartle, John T; Choate, Ashley L; Mahanna, Elizabeth P; Meyer, Cassie L; Tucker, Matthew C; Wang, Virginia; Allen, Kelli D; Van Houtven, Courtney H; Hastings, Susan NicoleHospitalization is common among older adults. Prolonged time in bed during hospitalization can lead to deconditioning and functional impairments. Our team is currently working with Department of Veterans Affairs (VA) medical centers across the United States to implement STRIDE (assiSTed eaRly mobIlity for hospitalizeD older vEterans), a hospital-based walking program designed to mitigate the risks of immobility during hospitalization. However, the COVID-19 pandemic made in-person, or face-to-face, walking challenging due to social distancing recommendations and infection control concerns. In response, our team applied principles of implementation science, including stakeholder engagement, prototype development and refinement, and rapid dissemination and feedback, to create STRIDE in Your Room (SiYR). Consisting of self-guided exercises, light exercise equipment (e.g., TheraBands, stress ball, foam blocks, pedometer), the SiYR program provided safe alternative activities when face-to-face walking was not available during the pandemic. We describe the methods used in developing the SiYR program; present feedback from participating sites; and share initial implementation experiences, lessons learned, and future directions.
