Annual prevalences of antimicrobial resistance among urine isolates (3,913 Escherichia coli isolates and 1,736 Klebsiella pneumoniae isolates) from home-based primary care patients with dementia were high between 2014 and 2018 (ciprofloxacin, 18%–23% and 5%–7%, respectively; multidrug resistance, 9%–11% and 5%–6%, respectively). Multidrug resistance varied by region. Additional studies of antimicrobial resistance in home-care settings are needed.

Family caregivers offer essential support to persons living with dementia (PLWD). Providing care for more than one family member or close other across adulthood is becoming increasingly common, yet little is known about the ways that caregiving experiences shape caregiver preparedness. The current study presents a grounded theory of future caregiver preparedness in former caregivers of PLWD.A coding team (five coders and two auditors) used Consensual Qualitative Research and grounded theory techniques to analyze transcripts from 32 semi-structured interviews with midlife former caregivers of parents who died following advanced Alzheimer's disease and related dementias.Qualitative analysis revealed two dimensions of future caregiver preparedness: caregiving confidence and caregiving insights. Narratives from caregiving experiences informed participants' descriptions of their future caregiver preparedness. Though some former caregivers described a positive (i.e., boosted or sustained) sense of caregiving confidence following care for their parents, others described a diminished (i.e., restricted or impeded) sense of confidence. Regardless of their confidence, all caregivers described specific caregiving insights related to one or more categories (i.e., caregiving self-conduct, care systems and resources, and relating with a care partner).Preparedness for future caregiving following recent care for a PLWD varies: For some, past experiences appear to offer cumulative advantages in anticipating future care roles, whereas for others, past experiences may contribute to apprehension towards, or rejection of, future care roles. Entering new caregiving roles with diminished confidence may have negative consequences for caregivers' and care partners' wellbeing. Multidimensional assessment of future caregiver preparedness in former caregivers of PLWD may support development of resources for former caregivers entering new caregiving roles.

ImportanceThere is a tension between clinician-led approaches to engagement in advance care planning (ACP), which are effective but resource-intensive, and self-administered tools, which are more easily disseminated but rely on ability and willingness to complete.ObjectiveTo examine the efficacy of computer-tailored print feedback (CTPF), motivational interviewing (MI), and motivational enhancement therapy (MET) on completion of a set of ACP activities, each as compared with usual care.Design, Setting, and ParticipantsThis randomized clinical trial was conducted from October 2017 to December 2020 via telephone contact with primary care patients at a single VA facility; 483 veterans aged 55 years or older were randomly selected from a list of patients with a primary care visit in the prior 12 months, with oversampling of women and people from minoritized racial and ethnic groups. Statistical analysis was performed from January to June 2022.InterventionsMailed CTPF generated in response to a brief telephone assessment of readiness to engage in and attitudes toward ACP; MI, an interview exploring ambivalence to change and developing a change plan; and MET, MI plus print feedback, delivered by telephone at baseline, 2, and 4 months.Main Outcome and MeasuresSelf-reported completion of 4 ACP activities: communicating about views on quality vs quantity of life, assignment of a health care agent, completion of a living will, and submitting documents for inclusion in the electronic health record at 6 months.ResultsThe study included 483 persons, mean (SD) age 68.3 (8.0) years, 18.2% women and 31.1% who were people from minoritized racial and ethnic groups. Adjusting for age, education, race, gender, and baseline stage of change for each ACP, predicted probabilities for completing the ACP activities were: usual care 5.7% (95% CI, 2.8%-11.1%) for usual care, 17.7% (95% CI, 11.8%-25.9%; P = .003) for MET, 15.8% (95% CI, 10.2%-23.6%; P = .01) for MI, P = .01, and 10.0% (95% CI, 5.9%-16.7%; P = .18) for CTPF.Conclusions and RelevanceThis randomized clinical trial found that a series of 3 MI and MET counseling sessions significantly increased the proportion of middle-aged and older veterans completing a set of ACP activities, while print feedback did not. These findings suggest the importance of clinical interaction for ACP engagement.Trial RegistrationClinicalTrials.gov Identifier: NCT03103828

to explore the effects of a deprescribing intervention on primary care clinicians' medication-related communication.A clinical decision support tool provided clinicians in the intervention group with an individualized report regarding potentially inappropriate medications (PIMs), deintensification of diabetes and/or hypertension treatment, and poor adherence/cognition. Participants included 113 Veterans aged ≥ 65 prescribed ≥ 7 medications and their primary care clinicians. Encounters were recorded and analyzed.Between 36% and 38% of intervention clinicians discussed PIMs and diabetes mellitus/hypertension deintensification and 94% discussed adherence. PIMs discussions referred to the report and prompted some medication changes. The diabetes mellitus/hypertension and adherence discussions were not prompted by the report but instead arose from enhanced medication reconciliation. Changes in diabetes mellitus/hypertension medications were not made out of overtreatment concerns. There was no deprescribing for nonadherence. Enhanced medication reconciliation also led to discussions about medications not in the report.An individualized report regarding medication appropriateness prompted clinicians to perform a more thorough medication reconciliation and discuss PIMs. It did not prompt chronic care deintensification or deprescribing to enhance adherence.Feedback reports can promote robust medication reconciliation in primary care. Changing clinician practice to achieve deprescribing in chronic disease management will be more challenging.

Objectives To identify and examine heterogeneous trajectories of general health status (GHS) and depressive symptoms (DS) among persons with cognitive impairment (PCIs). Methods: We use group-based trajectory models to study 2361 PCIs for GHS and 1927 PCIs for DS from the National Health and Aging Trends Survey 2011–2018, and apply multinomial logistic regressions to predict identified latent trajectory group memberships using individual characteristics. Results: For both GHS and DS, there were six groups of PCIs with distinct trajectories over a 7-year period. More than 40% PCIs experienced sharp declines in GHS, and 35.5% experienced persistently poor GHS. There was greater heterogeneity in DS trajectories with 55% PCIs experiencing improvement, 16.4% experiencing persistently high DS, and 30.5% experiencing deterioration. Discussion: The GHS trajectories illustrate the heavy burden of poor and declining health among PCIs. Further research is needed to understand the factors underlying stable or improving DS despite declining GHS

Context While medical end-of-life planning has been well characterized, less is known about non-medical planning to prepare for the end of life. Objectives To determine the prevalence of engagement in non-medical end-of-life (EOL) planning and its relationship to medical EOL planning. Methods Three hundred and four persons age 65 and older recruited from physician offices and a senior center were administered an in-person interview asking about participation in the following non-medical EOL planning behaviors: moving to a location with more help, teaching someone to do things around the house, purchasing long-term care insurance, telling someone the location of important documents, preparing a financial will, conveying wishes for funeral arrangements, purchasing a cemetery plot, and prepaying for a funeral. Results Prevalence of participation in the different non-medical EOL planning activities varied widely, from 8% for prepaying for a funeral to 84% for telling someone the location of important documents. There was little overlap in the factors associated with participation in each activity. Conveying wishes for funeral arrangements and completing a financial will were associated with completing a living will (OR 2.69, 95% CI 1.51, 4.78; OR 6.70, 95% CI 3.18, 14.15) and communication about quality versus quantity of life (OR 4.52, 95% CI 2.54, 8.04; OR 2.47, 95% CI 1.25, 4.86). Conclusion There is variability in both the prevalence of and factors associated with engagement in non-medical EOL planning activities. The association of non-medical with medical planning activities supports the utility of programs assisting individuals with broad engagement in EOL planning.

Background Hospital admissions for severe hypoglycemia are associated with significant healthcare costs, decreased quality of life, and increased morbidity and mortality, especially for older adults with diabetes. Understanding the reasons for hypoglycemia hospitalization is essential for the development of effective interventions; yet, the causes and precipitants of hypoglycemia are not well understood. Methods We conducted a qualitative study of non-nursing home patients aged 65 years or older without cognitive dysfunction admitted to a single tertiary-referral hospital with diabetes-related hypoglycemia. During the hospitalization, we conducted one-on-one, in-depth, semi-structured interviews to explore: (1) experiences with diabetes management among patients hospitalized for severe hypoglycemia; and (2) factors contributing and leading to the hypoglycemic event. Major themes and sub-themes were extracted using the constant comparative method by 3 study authors. Results Among the 17 participants interviewed, the mean age was 78.9 years of age, 76.5% were female, 64.7% African American, 64.7% on insulin, and patients had an average of 13 chronic conditions. Patients reported: (1) surprise at hypoglycemia despite living with diabetes for many years; (2) adequate support, knowledge, and preparedness for hypoglycemia; (3) challenges balancing a diet that minimizes hyperglycemia and prevents hypoglycemia; (4) the belief that hyperglycemia necessitates medical intervention, but hypoglycemia does not; and (5) tension between clinician-prescribed treatment plans and self-management based on patients’ experience. Notably, participants did not report the previously cited reasons for hypoglycemia, such as food insecurity, lack of support or knowledge, or treatment errors. Conclusions Our findings suggest that some hypoglycemic events may not be preventable, but in order to reduce the risk of hypoglycemia in older individuals at risk: (1) healthcare systems need to shift from their general emphasis on the avoidance of hyperglycemia towards the prevention of hypoglycemia; and (2) clinicians and patients need to work together to design treatment regimens that fit within patient capacity and are flexible enough to accommodate life’s demands.

Background physical functioning impairment is common among persons with cognitive impairment, but little is known about physical functioning trajectories across the US population or how trajectories may differ among persons with dementia and mild cognitive impairment (MCI). Objective to examine trajectories of physical functioning among persons with MCI and dementia in the USA. Design we used data from the National Health and Aging Trends study (NHATS) 2011–18. Physical functioning was assessed using the NHATS Expanded Short Physical Performance Battery. Participants the 661 individuals with MCI and 980 individuals with dementia were included in this study. Methods we applied group-based trajectory models to identify latent groups and estimate their trajectories. Multinomial logistic regressions were applied to examine relationships between sociodemographic and health characteristics and trajectory group memberships. Results both MCI- and dementia-specific trajectories differed at baseline levels and declined at varying rates across groups. Approximately, 78.43% of persons with MCI were in trajectories with a moderate rate of decline, with only 9.75% in a trajectory with good physical function and 11.82% with poor physical function without as much change over time. Among persons with dementia, approximately 81.4% experienced moderate or fast declines, and 18.52% with virtually no functional ability remained at this same low level. Worse physical functioning trajectories were found among persons who were females, Blacks, with at least four comorbidities, and among persons who had a low socioeconomic status. Conclusions persons with both dementia and MCI experienced steady declines in physical functioning. Socioeconomically disadvantaged groups have worse physical functioning trajectories.

INTRODUCTIONAfter emergency department (ED) discharge, persons living with cognitive impairment (PLWCI) and their care partners are particularly at risk for adverse outcomes. We sought to identify the barriers experienced by care partners of PLWCI during ED discharge care transitions.METHODSWe conducted a qualitative study of 25 care partners of PLWCI discharged from four EDs. We used the validated 4AT and care partner-completed AD8 screening tools, respectively, to exclude care partners of older adults with concern for delirium and include care partners of older adults with cognitive impairment. We conducted recorded, semi-structured interviews using a standardized guide, and two team members coded and analyzed all professional transcriptions to identify emerging themes and representative quotations.RESULTSCare partners’ mean age was 56.7 years, 80% were female, and 24% identified as African American. We identified four major barriers regarding ED discharge care transitions among care partners of PLWCI: 1) unique care considerations while in the ED setting impact the perceived success of the care transition, 2) poor communication and lack of care partner engagement was a commonplace during the ED discharge process, 3) care partners experienced challenges and additional responsibilities when aiding during acute illness and recovery phases, and 4) navigating the health care system after an ED encounter was perceived as difficult by care partners.DISCUSSIONOur findings demonstrate critical barriers faced during ED discharge care transitions among care partners of PLWCI. Findings from this work may inform the development of novel care partner-reported outcome measures as well as ED discharge care transition interventions targeting care partners.

Background The concern posed by the confluence of aging and cognitive impairment is growing in importance as the U.S. population rapidly ages. As such, we sought to examine the predictive power of physical functioning (PF) and general health status (GHS) trajectories on mortality outcomes among persons with cognitive impairment (PCIs). Methods We used group-based trajectory models to identify latent group memberships for PF trajectories in 1,641 PCIs and GHS trajectories in 2,021 PCIs from the National Health and Aging Trends Survey (2011–2018) and applied logistic regressions to predict mortality using these memberships controlling for individual characteristics. Results We identified six trajectory groups for PF and four groups for GHS. Trajectory group memberships for both outcomes significantly predicted mortality. For PF, group memberships largely captured the average levels over time, and worse trajectories (i.e., lower baselines and faster declines) were associated with higher odds of death. The highest mortality risk was associated with the group experiencing a sharp decline early in its PF trajectory, although its average level across time was not the lowest. For GHS, we observed two groups with comparable average levels across time, but the one with a convex-shape trajectory had much higher mortality risks compared to the one with a concave-shape trajectory. Conclusions Our findings highlighted that health trajectories predicted mortality among PCIs, not only because of general levels but also because of the shapes of declines. Close monitoring health deterioration of PCIs is crucial to understand the health burden of this population and to make subsequent actions.

Although advance care planning (ACP) is beneficial if dementia develops, and virtually all older adults are at risk for this disease, older adults do not consistently engage in ACP. Health behavior models have highlighted the importance of perceived susceptibility to medical conditions in motivating behavior. Following these models, we sought to determine how often older adults believe they are not at risk of developing dementia and to examine the association between perceived dementia risk and ACP participation.We performed a cross-sectional study of community-dwelling adults without cognitive impairment, aged ≥65 years, who were interviewed for the Health and Retirement Study in 2016 and asked about their perceived dementia risk (n = 711). Perceived dementia risk was ascertained with this question: "on a scale of 0 to 100, what is the percent chance that you will develop dementia sometime in the future?" We used multivariable-adjusted logistic regression to evaluate the association between perceived risk (0% versus0%) and completion of a living will, appointment of a durable power of attorney for healthcare decisions, and discussion of treatment preferences.Among respondents, 10.5% reported a perceived dementia risk of 0%. Perceived risk of 0% was associated with lower odds of completing a living will (OR 0.53; 95% CI, 0.30-0.93) and discussing treatment preferences (OR 0.51; 95% CI, 0.28-0.93) but not appointment of a durable power of attorney (OR 0.77; 95% CI, 0.42-1.39). Many respondents with perceived dementia risk0% had not completed ACP activities, including a substantial minority of those with perceived risk50%.Older adults with no perceived dementia risk are less likely to participate in several forms of ACP, but the fact that many older adults with high levels of perceived risk had not completed ACP activities suggests that efforts beyond raising risk awareness are needed to increase engagement.

Objectives Concerns have repeatedly been raised about end-of-life decision making when a patient with diminished capacity is represented by a professional guardian, a paid official appointed by a judge. Such guardians are said to choose high-intensity treatment even when it is unlikely to be beneficial or to leave pivotal decisions to the court. End-of-life decision making by professional guardians has not been examined systematically, however. Design Retrospective cohort study. Setting Inpatient and outpatient facilities in the Department of Veterans Affairs (VA) Connecticut Healthcare System. Participants Decedent patients represented by professional guardians who received care at Connecticut VA facilities from 2003 to 2013 and whose care in the last month of life was documented in the VA record. Measurements Through chart reviews, we collected data about the guardianship appointment, the patient's preferences, the guardian's decision-making process, and treatment outcomes. Results There were 33 patients with professional guardians who died and had documentation of their end-of-life care. The guardian sought judicial review for 33%, and there were delays in decision making for 42%. In the last month of life, 29% of patients were admitted to the intensive care unit, intubated, or underwent cardiopulmonary resuscitation; 45% received hospice care. Judicial review and high-intensity treatment were less common when information about the patient's preferences was available. Conclusion Rates of high-intensity treatment and hospice care were similar to older adults overall. Because high-intensity treatment was less likely when the guardian had information about a patient's preferences, future work should focus on advance care planning for individuals without an appropriate surrogate.

Background/objectives To determine the feasibility of conducting a cluster randomized controlled trial providing individualized feedback reports to increase advance care planning (ACP) engagement in the primary care setting. Design Pilot cluster randomized controlled trial. Setting Two primary care practices selected for geographic colocation. Participants Adults aged 55 years and older. Intervention Brief assessment of readiness to engage in (stage of change for) three ACP behaviors (healthcare agent assignment, communication with agent about quality vs quantity of life, and living will completion) generating an individualized feedback report, plus a stage-matched brochure. Measures Patient recruitment and retention, intervention delivery, baseline characteristics, and stage of change movement. Results Recruitment rates differed by practice. Several baseline sociodemographic characteristics differed between the 38 intervention and 41 control participants, including employment status, education, and communication with healthcare agent. Feedback was successfully delivered to all intervention participants, and over 90% of participants completed a 2-month follow-up. More intervention participants demonstrated progression in readiness than did control participants, without testing for statistical significance. Conclusions This pilot demonstrates opportunities and challenges of performing a clustered randomized controlled trial in primary care practices. Differences in the two practice populations highlight the challenges of matching sites. There was a signal for behavior change in the intervention group. J Am Geriatr Soc 67:1917-1921, 2019.

BACKGROUND: Polypharmacy and potentially inappropriate medications (PIMs) are increasingly common and associated with adverse health effects. However, post-graduate education in polypharmacy and complex medication management for older adults remain limited. OBJECTIVE: The Initiative to Minimize Pharmaceutical Risk in Older Veterans (IMPROVE) polypharmacy clinic was created to provide a platform for teaching internal medicine (IM) and nurse practitioner (NP) residents about outpatient medication management and deprescribing for older adults. We aimed to assess residents’ knowledge of polypharmacy and perceptions of this interprofessional education intervention. DESIGN: A prospective cohort study with an internal comparison group. PARTICIPANTS: IM residents and NP residents; Veterans ≥ 65 years and taking ≥ 10 medications. INTERVENTION: IMPROVE consists of a pre-clinic conference, shared medical appointment, individual appointment, and interprofessional precepting model. MAIN MEASURES: We assessed residents’ performance on a pre-post knowledge test, residents’ qualitative assessment of the educational impact of IMPROVE, and the number and type of medications discontinued or decreased. KEY RESULTS: The IMPROVE intervention group (n = 18) had a significantly greater improvement in test scores than the control group (n = 18) (14% ± 15% versus − 1.3% ± 16%) over a period of 6 months (Wilcoxon rank sum, p = 0.019). In focus groups, residents (n = 17) reported perceived improvements in knowledge and skills, noting that the experience changed their practice in other clinical settings. In addition, residents valued the unique interprofessional experience. Veterans (n = 71) had a median of 15 medications (IQR 12–19), and a median of 2 medications (IQR 1–3) was discontinued. Vitamins, supplements, and cardiovascular medications were the most commonly discontinued medications, and cardiovascular medications were the most commonly decreased in dose or frequency. CONCLUSIONS: Overall, IMPROVE is an effective model of post-graduate primary care training in complex medication management and deprescribing that improves residents’ knowledge and skills, and is perceived by residents to influence their practice outside the program.

Background Interventions with the potential for broad reach in ambulatory settings are necessary to achieve a life course approach to advance care planning. Objective To examine the effect of a computer-tailored, behavioral health model-based intervention on the engagement of adults in advance care planning recruited from ambulatory care settings. Design Cluster randomized controlled trial with participant-level analysis. (ClinicalTrials.gov: NCT03137459). Setting 10 pairs of primary and selected specialty care practices matched on patient sociodemographic information. Participants English-speaking adults aged 55 years or older; 454 adults at practices randomly assigned to usual care and 455 at practices randomly assigned to intervention. Intervention Brief telephone or web-based assessment generating a mailed, individually tailored feedback report with a stage-matched brochure at baseline, 2 months, and 4 months. Measurements The primary outcome was completion of the following 4 advance care planning activities at 6 months: identifying and communicating with a trusted person about views on quality versus quantity of life, assignment of a health care agent, completion of a living will, and ensuring that the documents are in the medical record-assessed by a blinded interviewer. Secondary outcomes were completion of individual advance care planning activities. Results Participants were 64% women and 76% White. The mean age was 68.3 years (SD, 8.3). The predicted probability of completing all advance care planning activities in usual care sites was 8.2% (95% CI, 4.9% to 11.4%) versus 14.1% (CI, 11.0% to 17.2%) in intervention sites (adjusted risk difference, 5.2 percentage points [CI, 1.6 to 8.8 percentage points]). Prespecified subgroup analysis found no statistically significant interactions between the intervention and age, education, or race. Limitations The study was done in a single region and excluded non-English speaking participants. No information was collected about nonparticipants. Conclusion A brief, easily delivered, tailored print intervention increased participation in advance care planning in ambulatory care settings. Primary funding source National Institute of Nursing Research and National Institute of Aging.

Context Advance care planning remains underutilized. A better understanding of the role of education in promoting engagement is needed. Objectives To examine advance care planning knowledge and its relationship to engagement in middle-aged and older adults. Methods This cross-sectional study utilized baseline data from 921 participants age ≥55 years enrolled in the STAMP randomized controlled trial, including a knowledge scale consisting of seven questions regarding the purpose and mechanisms of advance care planning and measures of participation. Results Only 11.9% of participants answered all 7 questions correctly, and 25.6% of participants answered ≤3 correctly (defined as “low knowledge”). Low knowledge was independently associated with male gender (odds ratio [OR] 2.1, 95% confidence interval [CI]: 1.5, 3.0), non-white race (OR 1.5, 95% CI: 1.1, 2.2), older age (OR 2.2, 95% CI: 1.4, 3.4), lower income (OR 1.5, 95% CI: 1.1, 2.1), and lower education level (OR 2.9, 95% CI: 2.0, 4.1). Higher knowledge was independently associated with communicating with a loved one about quality versus quantity of life (OR 1.7, 95% CI: 1.2, 2.4) and with living will completion (OR 1.6, 95% CI: 1.0, 2.5), but not with healthcare agent assignment. Factors including race and education remained associated with engagement after accounting for knowledge. Conclusion Knowledge deficits regarding advance care planning are common and associated with the same sociodemographic factors linked to other healthcare disparities. While improving knowledge is an important component of intervention, it is unlikely sufficient in and of itself to increase engagement.

Background/objectives Advance care planning (ACP) traditionally involves asking individuals about their treatment preferences during a brief period of incapacity near the end of life. Because dementia leads to prolonged incapacity, with many decisions arising before a terminal event, it has been suggested that dementia-specific ACP is necessary. We sought to elicit the perspectives of older adults with early cognitive impairment and their caregivers on traditional and dementia-specific ACP. Design Qualitative study with separate focus groups for patients and caregivers. Setting Memory disorder clinics. Participants Twenty eight persons aged 65+ with mild cognitive impairment or early dementia and 19 caregivers. Measurements Understanding of dementia trajectory and types of planning done; how medical decisions would be made in the future; thoughts about these decisions. Results No participants had engaged in any written form of dementia-specific planning. Barriers to dementia-specific ACP emerged, including lack of knowledge about the expected trajectory of dementia and potential medical decisions, the need to stay focused in the present because of fear of loss of self, disinterest in planning because the patient will not be aware of decisions, and the expectation that involved family members would take care of issues. Some patients had trouble engaging in the discussion. Patients had highly variable views on what the quality of their future life would be and on the leeway their surrogates should have in decision making. Conclusions Even among patients with early cognitive impairment seen in specialty clinics and their caregivers, most were unaware of the decisions they could face, and there were many barriers to planning for these decisions. These issues would likely be magnified in more representative populations, and highlight challenges to the use of dementia-specific advance directive documents.

Background National institutes and education initiatives emphasize the need to prepare future biologists to apply discoveries in science towards solving problems that are both social and scientific in nature. Research from socio-scientific, design-based, and problem-based learning demonstrates that contextualized, real-world tasks can improve students’ ability to apply their scientific knowledge in practical ways to navigate social problems. Biomimicry Design is an interdisciplinary field requiring biology and design skills; it informs the creation of sustainable designs through emulation of biological structures and functions that arise as a result of natural selection. Notably, engaging in biomimicry design targets an important biology and engineering learning outcome: understanding of how structure influences function. This study leveraged the practices of biomimicry along with those of design-based learning (DBL) to improve student outcomes in an evolutionary biology undergraduate course. Through DBL, the authors aimed to (1) ignite deeper understanding of how structure determines function in nature (a cross-disciplinary concept) and (2) help students to consider new ways this concept can benefit society (a science process skill). Results We randomly assigned two sections of an upper-division evolutionary biology course to either a biomimicry DBL (DBL group) or species comparison (comparison group) curricular design. Students in the course were exposed to a 1-day lesson, then 1-weeklong case study, and then a final project focused on either biomimicry species-to-human design comparisons (DBL condition) or species-to-species comparisons (comparison condition). To assess the targeted outcomes, we analyzed students’ responses from a pre-post assessment. Students in the biomimicry section were more likely to apply their biological structure–function knowledge to societal benefits when leaving the course. Students in both sections showed comparable gains in structure–function understanding, but there was no change in the number of students who used misconception language in their post-course compared to pre-course responses. Conclusions We conclude that our DBL curriculum, above and beyond the comparison curriculum, may support students’ ability to apply biological concepts to societal benefits without compromising structure–function understanding. Overall, these results provide rationale for incorporating tasks situated in DBL to address socio-scientific issues in biology courses.

Prognosis communication in heart failure is often narrowly defined as a discussion of life expectancy, but as clinical guidelines and research suggest, these discussions should provide a broader understanding of the disease, including information about disease trajectory, the experiences of living with heart failure, potential burden on patients and families, and mortality. Furthermore, despite clinical guidelines recommending early discussions, evidence suggests that these discussions occur infrequently or late in the disease trajectory. We review the literature concerning patient, caregiver, and clinician perspectives on discussions of this type, including the frequency, timing, desire for, effects of, and barriers to their occurrence. We propose an alternate view of prognosis communication, in which the patient and family/caregiver are educated about the nature of the disease at the time of diagnosis, and a process of engagement is undertaken so that the patient's full participation in their care is marshalled, and the care team engages the patient in the informed decision making that will guide care throughout the disease trajectory. We also identify and discuss evidence gaps concerning (i) patient preferences and readiness for prognosis information along the trajectory; (ii) best practices for communicating prognosis information; and (iii) effects of prognosis communication on patient's quality of life, mental health, engagement in critical self‐care, and clinical outcomes. Research is needed to determine best practices for engaging patients in prognosis communication and for evaluating the effects of this communication on patient engagement and clinical outcomes.

Background/objectives Little is known about older adults who have intact capacity but do not have a desired surrogate to make decisions if their capacity becomes impaired. Design Cross-sectional study of a nationally representative sample. Setting National Social Life, Health, and Aging Project (NSHAP), 2005-2006. Participants Community-dwelling older adults without known cognitive impairment, aged 57 to 85, interviewed as part of NSHAP (n = 2,767). Measurements We examined demographic, medical, and social connectedness characteristics associated with answering "no" to this question: "Do you have someone who you would like to make medical decisions for you if you were unable, as for example if you were seriously injured or very sick?" Because many states permit nuclear family to make decisions for persons with no legally appointed health care agent, we used logistic regression to identify factors associated with individuals who were ill suited to this paradigm in the sense that they had nuclear family but did not have a desired surrogate. Results Among NSHAP respondents, 7.5% (95% confidence interval = 6.4-8.7) did not have a desired surrogate. Nearly 90% of respondents without desired surrogates had nuclear family. Compared with respondents with desired surrogates, those without desired surrogates had lower indicators of social connectedness. On average, however, they had four confidants, approximately 70% socialized at least monthly, and more than 90% could discuss their health with a confidant. Among respondents who had nuclear family, few characteristics distinguished those with and without desired surrogates. Conclusion Nearly 8% of older adults did not have a desired surrogate. Most had nuclear family and were not socially disconnected. Older adults should be asked explicitly about a desired surrogate, and strategies are needed to identify surrogates for those who do not have family or would not choose family to make decisions for them.

Older adults are prescribed a growing number of medications. Polypharmacy, commonly considered the receipt of five or more medications, is associated with a range of adverse outcomes. There is a debate about the reason(s) why. On one side is the assertion that older persons are being prescribed too many medications, with the number of medications increasing the risk of adverse events. On the other side is the observation that polypharmacy is associated both with overprescribing of inappropriate medications and underprescribing of appropriate medications. This leads to the concept of "inappropriate" vs "appropriate" polypharmacy, with the latter resulting from the prescription of many correct medications to persons with multiple chronic conditions. Few studies have examined the health outcomes associated with adding and/or removing medications to address this debate directly. The criteria used to identify underutilized medications are based on results of randomized controlled trials that may not be generalizable to older adults. Several randomized controlled trials and many more observational studies provide evidence that these criteria overestimate medication benefits and underestimate harms. In addition, evidence suggests that the marginal effects of medications added to an already complex regimen differ from their effects when considered individually. Although in selected circumstances adding medications results in benefit to patients, patients with multimorbidity and frailty/disability have susceptibilities that can decrease the likelihood of medication benefit and increase the likelihood of harms. The identification of appropriate polypharmacy requires more robust criteria to evaluate the net effects of complex medication regimens.

Background/objectives Experts have suggested that patients represented by professional guardians receive higher intensity end-of-life treatment than other patients, but there is little corresponding empirical data. Design Retrospective cohort study. Setting and participants Among veterans aged 65 and older who died from 2011 to 2013, we used Minimum Data Set assessments to identify those who were nursing home residents and had moderately severe or severe dementia. We applied methods developed in prior work to determine which of these veterans had professional guardians. Decedent veterans with professional guardians were matched to decedent veterans without guardians in a 1:4 ratio, according to age, sex, race, dementia severity, and nursing facility type (VA based vs non-VA). Measurements Our primary outcome was intensive care unit (ICU) admission in the last 30 days of life. Secondary outcomes included mechanical ventilation and cardiopulmonary resuscitation in the last 30 days of life, feeding tube placement in the last 90 days of life, three or more nursing home-to-hospital transfers in the last 90 days of life, and in-hospital death. Results ICU admission was more common among patients with professional guardians than matched controls (17.5% vs 13.7%), but the difference was not statistically significant (adjusted odds ratio = 1.33; 95% confidence interval = .89-1.99). There were no significant differences in receipt of any other treatment; nor was there a consistent pattern. Mechanical ventilation and cardiopulmonary resuscitation were more common among patients with professional guardians, and feeding tube placement, three or more end-of-life hospitalizations, and in-hospital death were more common among matched controls. Conclusion Rates of high-intensity treatment were similar whether or not a nursing home resident with dementia was represented by a professional guardian. This is in part because high-intensity treatment occurred more frequently than expected among patients without guardians.

OBJECTIVES To examine factors associated with caregiver burden from a multifactorial perspective by examining caregiver and care recipient characteristics and a full range of caregiving tasks. DESIGN Nationally representative surveys of community‐dwelling older adults and their family caregivers residing in the United States. SETTING 2011 National Health and Aging Trends Study and National Study of Caregiving. PARTICIPANTS Community‐dwelling older adults and their family caregivers. MEASUREMENTS Caregiver burden, comprising emotional, physical, and financial difficulties associated with caregiving. RESULTS An estimated 14.9 million caregivers assisted 7.6 million care recipients. More than half of caregivers reported burden related to caregiving. In a multivariable regression model, caregivers who assisted with more activities of daily living and instrumental activities of daily living, health management tasks, and health system logistics were more likely to experience burden, as were female caregivers, adult child caregivers, caregivers in poor health, caregivers with anxiety symptoms, and those using respite care. Dementia was the only care recipient characteristic associated with burden. CONCLUSION Caregiver characteristics and provision of caregiving tasks determine caregiver burden more than care recipient characteristics. Absence of an association between type of a care recipient's chronic conditions and burden, except for dementia, suggests that the tasks that caregivers who assist older adults with a variety of health conditions undertake shape the experience of caregiving.

Solid-state nanomaterials exhibit complementary interactions with biological systems because of their biologically-relevant size scales and rationally tunable electrical, chemical and mechanical properties. In this review, we focus specifically on one-dimensional (1D) nanomaterials such as silicon or gold nanowires or carbon nanotubes. We discuss the nature of the nanomaterial–cell interface, and how that interface may be engineered to enhance or modulate cellular function. We then describe how those unique interfaces may be exploited in three-dimensional (3D) tissue culture to recapitulate the extracellular matrix and promote or complement morphogenesis. Finally, we describe how 1D nanomaterials may be elucidated as nanoelectronic devices that monitor the chemical or electrical environment of cells or tissue with exquisite spatial and temporal resolution. We discuss prospects for entirely new classes of engineered, hybrid tissues with rationally-designed biological function and two-way, closed-loop electronic communication.

Objectives To explore patient and caregiver experiences, preferences, and attitudes toward the provision and receipt of caregiving assistance with medical tasks. Design Qualitative study consisting of in‐depth interviews with 20 patient–caregiver dyads. Setting Community and academic‐affiliated primary care clinics. Participants Individuals aged 65 or older with 2 or more health conditions and their family caregivers (n=20 patient–caregiver dyads). Measurements Open‐ended questions were asked about the tasks that the patient and caregiver performed to manage the patient's health conditions; questions were designed to elicit participant reactions and attitudes toward the help they provided or received. Transcripts were analyzed using the constant comparative method. Results Participant preferences and attitudes toward the receipt and provision of disease management tasks were highly personal. Participant responses clustered into 2 caregiving typologies: supportive caregiving relationships and conflicted caregiving relationships. Supportive relationships were characterized by patient–caregiver agreement about caregiver level of involvement, agreement about one another's competency to perform disease‐related tasks, mutual understanding, collaborative decision‐making and disease management, and use of family and formal caregiving. Conflicted relationships were characterized by disagreement about caregiver level of involvement, disagreement about one another's competency to perform disease management tasks, underappreciation of one another's experiences, disagreement over decision‐making and disease management, and use of formal caregiving. Conclusions The views that patient–caregiver dyads expressed in this study illustrate the varied preferences and attitudes toward caregiving assistance with multiple health conditions. These findings support a dyadic approach to evaluating and addressing patient and caregiver needs and attitudes toward provision of assistance.

The increasing use of the question, "What matters most to you?" is a welcome development in the effort to provide patient-centered care. However, it is difficult for clinicians to translate answers to this question into treatment plans for chronic conditions, including recognizing when to consider options other than clinical practice guideline (CPG)-directed therapy. Goal elicitation is most helpful when a patient has different treatment options with clearly identifiable trade-offs. In the face of trade-offs, goal elicitation helps patients to prioritize among potentially competing outcomes. While decision aids (DAs) focus on trade-offs by delineating options and outcomes, the robust outcome data necessary to create DAs for older patients with multimorbidity are often lacking and even mild cognitive impairment makes the use of DAs difficult. The challenges for providing chronic disease care to older patients who are at risk for adverse events from CPG-directed therapy because of multimorbidity and/or frailty are to organize the complexity of individual combinations of diseases, conditions, and syndromes into common sets of trade-offs and to identify those goals or priorities that will directly inform a plan of care.

Whereas modern clinicians are often reluctant to discuss prognosis with their patients, such discussions were central to medical practice in ancient Greece. A historical analysis has the potential to explain the reasons for this difference in prognostic practices and provide insights into overcoming current challenges. Many scholars consider prognosis to be the principal scientific achievement of the Hippocratic tradition. The earliest treatise on the subject, On Prognostics, defines prognosis broadly as "foreseeing and foretelling, by the side of the sick, the present, the past, and the future." This definition makes clear that prognosis is not simply about predicting the future, but also involves an appreciation for the continuity of past, present, and future as sequences of connected events, or trajectories, that can be pieced together into a comprehensive story of the patient's health. In modern medicine, prognosis has lagged behind diagnosis and treatment in its establishment as a central component of medical care. An important basis for understanding this lies in the paradigm change that occurred with the discovery of pathogens as agents of disease, shifting attention toward individual diseases and away from diseased individuals. With this shift, diagnostics and treatments advanced dramatically and prognosis fell to the background. More recent attempts to advance prognosis have focused on narrower uses of the term, such as estimates of life expectancy and mortality risk. However, physicians have expressed a number of reservations about the use of such estimates in the care of patients, and patients have indicated the desire for a wide variety of predictive information. Adopting the broadness of the Hippocratic definition may allow clinicians to overcome their hesitancy and provide much-needed information to their patients.

This cross-sectional study evaluates the degree of anticoagulant use among nursing home residents with advanced dementia and atrial fibrillation at the end of life.

Objectives To understand the perspectives of both patients and the person who would make medical decisions for them if they were unable (surrogates) on their participation in advance care planning (ACP). Design Qualitative cross-sectional study. Setting Community. Participants Thirty-one veterans age 55 years and older and their surrogates. Measurements In interviews conducted with both the veteran and surrogate, they were asked to discuss their participation in four ACP activities: communication about life-sustaining treatment, communication about views on quality of life, completion of a living will, and appointment of a healthcare proxy. They were asked about barriers to and facilitators of ACP engagement. When they did not agree about engagement, they each provided their perspective on what they believed had or had not occurred. Results Many of the same barriers to and facilitators of engagement were discussed by both patients and surrogates. These included difficulty thinking about dying, differences in values, and experiences with others that demonstrated the ability of ACP to decrease burden or avoid conflict. Reasons for disagreements in perceptions about whether communication had occurred included surrogates’ need for more detailed information, surrogates’ lack of readiness to hear what the patient was saying, and surrogates’ reliance on what they know about the patient. For some dyads, participation in the study prompted additional communication, resulting in a better shared understanding of ACP engagement. Conclusion Surrogates can both impede and facilitate engagement in ACP, and they can hold different perceptions from patients regarding this engagement. Efforts to promote ACP may be most successful if they assess and address both patients’ and surrogates’ attitudes and help to facilitate clear communication between them.

This article provides an overview of the literature describing the effects of geriatric patients’ pain on family members’ relationships, psychological well-being, and physical health. The theoretical mechanisms that underlie the association between patients’ pain and family members’ outcomes are outlined, and studies describing these mechanisms are summarized. Limitations to the current literature are discussed, and key recommendations for future research and practice are presented.

Objectives To determine whether older adult spouses’ frailty states and depressive symptoms are interrelated over time. Design Longitudinal, dyadic path analysis using the Actor–Partner Interdependence Model. Setting Data were from baseline (1989–90), Wave 3 (1992–93), and Wave 7 (1996–97), all waves in which frailty and depressive symptoms were measured, of the Cardiovascular Health Study (CHS), a multisite, longitudinal, observational study of risk factors for cardiovascular disease in adults aged 65 and older. Participants Spouses in 1,260 community-dwelling married couples. Measurements Frailty was measured using the CHS criteria, categorized as nonfrail, prefrail, or frail. Depressive symptoms were measured using the 10-item Center for Epidemiologic Studies Depression Scale. Results Within individuals (actor effects), greater frailty predicted greater subsequent depressive symptoms, and greater depressive symptoms predicted greater subsequent frailty. Between spouses (partner effects), an individual's greater frailty predicted the spouse's greater frailty, and an individual's greater depressive symptoms predicted the spouse's greater depressive symptoms. Conclusion Frailty and depressive symptoms are interrelated in older adult spouses. For older couples, interventions to prevent or treat frailty and depression that focus on couples may be more effective than those that focus on individuals.
