Transforming Care for Older Adults Living with Complex Health Conditions in Ontario Post-Covid: Conference Proceedings and Recommendations.

The virtual conference 'Transforming Care: Supporting Older Adults Post-COVID in Ontario' was held in October 2021. It was organized by Specialized Geriatric Services (SGS) East and held over three half-days. The guiding themes included: The Need, The Innovation, and The Transformation. Over 500 participants heard from ~50 clinicians, researchers, administrators, older adults, care partners, and community partners. The pandemic uncovered and exacerbated existing issues and pushed us to explore new ways to support older adults living with complex health conditions. The following key priorities were identified: older adults and their care partners call for personalized care experiences, and a lifespan approach to care delivery; aging in the community remains the most common preference; an integrated community care system that supports aging at-home should be prioritized; care delivery by SGS interprofessional teams and specialists is paramount to providing comprehensive care; building health human resource capacity should be a system priority; and promising innovations should be scaled and spread. Evidence shows that we cannot return to status-quo; post-pandemic planning of both who we serve and how we serve needs to be anchored in system renewal, not just recovery. Renewal means integrating lessons learned during the pandemic into the redesign of our systems of care. Investments in innovative, upstream strategies that support home and community-based care, and target health promotion and prevention are necessary. The provincial and regional infrastructure of SGS has the expertise and capacity to assist Ontario Health Teams in responding to the evolving health and social needs of this population.

Enabling Healthy Aging to AVOID Frailty in Community Dwelling Older Canadians.

The Canadian population is aging. With aging, biological and social changes occur increasing the risk of developing chronic conditions and functional loss leading to frailty. Older adults living with frailty are more vulnerable to minor stressors, take longer to recover from illness, and have difficulty participating in daily activities. The Canadian Frailty Network's (CFN) mission is to improve the lives of older adults living with frailty. In September 2019, CFN launched the Activity & Exercise, Vaccination, Optimization of medications, Interaction & Socialization, and Diet & Nutrition (AVOID) Frailty public health campaign to promote assessing and reducing risk factors leading to the development of frailty. As part of the campaign, CFN held an Enabling Healthy Aging Symposium with 36 stakeholders from across Canada. Stakeholders identified individual and community-level opportunities and challenges for the enablement of healthy aging and frailty mitigation, as part of a focused consultative process. Stakeholders ranked the three most important challenges and opportunities at the individual and community levels for implementing AVOID Frailty recommendations. Concrete actions, further research areas, policy changes, and existing resources/programs to enhance the AVOID Frailty campaign were identified. The results will help inform future priorities and behaviour change strategies for healthy aging in Canada.

Postprandial zinc stable isotope response in human blood serum.

In recent years, considerable advances have been made in the field of medical isotope metallomics, but numerous fundamental physiological processes remain to be investigated. Past studies report that blood serum Zn concentrations decrease by between about 10 and 25%, depending on the size of meal, approximately three hours postprandially (i.e. after eating), before returning to baseline values if no meals are consumed over the following four to five hours. Nine participants were recruited for this study to investigate whether this postprandial Zn concentration decrease is accompanied by a stable isotope response. A baseline serum sample was collected from participants in the morning after overnight fasting. A 576 kcal meal was then provided and additional serum samples were taken 90 and 180 minutes post-meal to coincide with the postprandial response. Serum Zn concentrations decreased postprandially by an average of 21 ± 9% (1SD), but this was not accompanied by a change in stable Zn isotope composition (mean Δ66Zn180-minute-baseline = 0.01 ± 0.09‰, 2SD). We propose that hemodilution and the rapid, efficient postprandial transfer of albumin-bound Zn from serum to the liver and pancreas is responsible for the lack of postprandial serum Zn isotopic response. These results indicate that studies examining solely the distribution of Zn isotopes in serum may obtain samples without considering timing of the most recent meal. However, future studies seeking to compare serum Zn concentrations with δ66Zn values should draw blood samples in the morning after overnight fasting.

Effects of medical and non-medical cannabis use in older adults: protocol for a scoping review.

INTRODUCTION: With its legalisation and regulation in Canada in 2018, the proportion of Canadians reporting cannabis use in 2019 increased substantially over the previous year, with half of new users being aged 45+ years. While use in older adults has been low historically, as those born in the 1950s and 1960s continue to age, this demographic will progressively have more liberal attitudes, prior cannabis exposure and higher use rates. However, older adults experience slower metabolism, increased likelihood of polypharmacy, cognitive decline and chronic physical/mental health problems. There is a need to enhance knowledge of the effects of cannabis use in older adults. The following question will be addressed using a scoping review approach: what evidence exists regarding beneficial and harmful effects of medical and non-medical cannabis use in adults >50 years of age? Given that beneficial and harmful effects of cannabis may be mediated by patient-level (eg, age, sex and race) and cannabis-related factors (eg, natural vs synthetic, consumption method), subgroup effects related to these and additional factors will be explored. METHODS AND ANALYSIS: Methods for scoping reviews outlined by Arksey & O'Malley and the Joanna Briggs Institute will be used. A librarian designed a systematic search of the literature from database inception to June 2019. Using the OVID platform, Ovid MEDLINE will be searched, including Epub Ahead of Print and In-Process and Other Non-Indexed Citations, Embase Classic+Embase, and PsycINFO for reviews, randomised trials, non-randomised trials and observational studies of cannabis use. The Cochrane Library on Wiley will also be searched. Eligibility criteria will be older adult participants, currently using cannabis (medical or non-medical), with studies required to report a cannabis-related health outcome to be eligible. Two reviewers will screen citations and full texts, with support from artificial intelligence. Two reviewers will chart data. Tables/graphics will be used to map evidence and identify evidence gaps. ETHICS AND DISSEMINATION: This research will enhance awareness of existing evidence addressing the health effects of medical and non-medical cannabis use in older adults. Findings will be disseminated through a peer-reviewed publication, conference presentations and a stakeholder meeting. TRIAL REGISTRATION NUMBER: DOI 10.17605/OSF.IO/5JTAQ.

Promoting Quality Improvement in Long-Term Care: A Multi-Site Collaboration to Improve Outcomes with Pneumonia, Falls, Bacteriuria and Behavioural Issues in Dementia.

The Bridges to Care for Long-Term Care research project aimed to facilitate improvements in outcomes for long-term care residents through the provision of knowledge-to-practice and quality improvement resources by trained facilitators. Point-of-care staff reported improved communication and collaboration, improved use of scope of practice and implementation of best practice knowledge. Overall, participating long-term care homes demonstrated an enhanced capacity for common care issues of the elderly (pneumonia, falls, bacteriuria and behavioural and psychological symptoms of dementia) and the ability to effectively engage in quality improvement processes with efficient and effective use of healthcare resources.

Geriatrics, interprofessional practice, and interorganizational collaboration: a knowledge-to-practice intervention for primary care teams.

INTRODUCTION: Caring for frail seniors requires health professionals with skills and knowledge in 3 core competencies: geriatrics, interprofessional practice, and interorganizational collaboration. Despite a growing population of frail seniors in all developed countries, significant gaps exist in preparation of health professionals in these skills. To help close these gaps, a knowledge-to-practice (KTP) process was undertaken to increase the capacity of newly created family health teams and longer standing Community Health Centers in the Province of Ontario, Canada. METHODS: Each team identified a staff member to become its facilitator in the 3 core skill sets. Guided by a KTP framework, a set of training modules were created, compiled into a digital toolkit for transfer into practice, translated in a multimethods workshop, and implemented using a variety of strategies to optimize practice change. RESULTS: Staff from 82% of the targeted primary care teams learned to use the toolkit in a train-the-facilitator process that was highly valued, and prompted a range of changes in personal and team practice. A digital toolkit for primary care teams remains an enduring and often used resource. DISCUSSION: Closing the knowledge gap in the core competencies for frailty focused care is complex. A KTP framework helped guide a staged multimethod process that produced both individual and team practice change and on online toolkit that has a continuing influence.

Variability in physicians' decisions on caring for chronically ill elderly patients: an international study.

OBJECTIVES: To determine what treatment decisions physicians will make when faced with an incompetent elderly patient with life-threatening gastrointestinal bleeding and to identify the factors that affect their decisions. DESIGN: Survey. SETTING: Family practice, medical and geriatrics rounds in academic medical centres and community hospitals in seven countries. PARTICIPANTS: Physicians who regularly cared for incompetent elderly patients. OUTCOME MEASURE: A self-administered questionnaire containing three case vignettes. Each provided the same details on an incompetent elderly patient; however, one gave no information about the wishes of the patient and his family (no directive), the second provided a do-not-resuscitate (DNR) request, and the third included a detailed therapeutic and resuscitative effort chart (DTREC) requesting maximum therapeutic care without admission to the intensive care unit (ICU). The four treatment options were supportive care only, limited therapeutic care, maximum therapeutic care without admission to the ICU and maximum care with admission to the ICU. MAIN RESULTS: Treatment decisions varied and were systematically related to age, level of training and country (p less than 0.001). The older physicians and those in family medicine were less likely than the others to choose aggressive treatment options. Brazilian and US physicians were the most aggressive; Australian physicians were the most conservative. The DNR request resulted in a significant decrease in the number of physicians choosing aggressive options (p less than 0.001). The DTREC resulted in a move toward more aggressive treatment, as outlined in the directive (p less than 0.001). Overall, however, about 40% of the physicians chose a level of care different from what had been requested. Furthermore, over 10% would have tried cardiopulmonary resuscitation despite the DNR request. CONCLUSION: Treatment of incompetent elderly patients with life-threatening illness varies widely within and between countries. Uniform standards should be developed on the basis of societal values and be communicated to physicians.
