Exacerbated inequalities: A scoping review of the experiences of older persons during conflict situations.

BACKGROUND: We conducted the first known comprehensive literature review to (1) identify, categorize, and summarize the existing knowledge about the experiences of older persons and their caregivers during conflict situations; (2) identify the support needs of older persons and their caregivers, and; (3) identify gaps in the literature and understanding that may inform future research. METHODS: A scoping review methodology of academic peer-reviewed and gray English language literature was employed using six academic literature databases and one gray literature database. We further performed comprehensive searches of relevant search engines and organization websites and bibliographic hand searches to identify additional academic and gray literature. Two authors screened for eligibility of identified studies and documents. One reviewer extracted data regarding authors, article type, geographic origin, key participant characteristics, aims, study design and data collection method, results, conclusions and limitations. Data were analyzed thematically. RESULTS: 83 documents met this review's inclusion criteria, including 21 academic documents and 62 from the gray literature. Thematic analysis revealed that conflict situations exacerbate existing inequalities experienced by older persons. Within this overarching theme were three interconnected sub-themes: (1) Older adults are particularly vulnerable during conflict situations; (2) Older persons are inadequately supported in conflict situations; (3) In the face of great challenges, many older adults still manage to endure through conflict situations. We identified 15 recommendations from the reviewed documents to better support older adults in conflict situations. CONCLUSIONS: Existing inequalities, such as ageism and ableism, targeted discrimination, and poor health outcomes, become exacerbated during conflict situations, resulting in older persons being less able to flee and meet their daily needs with sufficient access to necessities and healthcare. Little is known of the experiences and needs of family caregivers during conflict situations. We identified several opportunities to improve the experience and support of older persons in conflict situations.

Cost-utility analysis of a multispecialty interprofessional team dementia care model in Ontario, Canada.

OBJECTIVES: To examine the cost-effectiveness of Multi-specialty INterprofessional Team (MINT) Memory Clinic care in comparison to the provision of usual care. DESIGN: Using a Markov-based state transition model, we performed a cost-utility (costs and quality-adjusted life years, QALY) analysis of MINT Memory Clinic care and usual care not involving MINT Memory Clinics. SETTING: A primary care-based Memory Clinic in Ontario, Canada. PARTICIPANTS: The analysis included data from a sample of 229 patients assessed in the MINT Memory Clinic between January 2019 and January 2021. PRIMARY OUTCOME MEASURES: Effectiveness as measured in QALY, costs (in Canadian dollars) and the incremental cost-effectiveness ratio calculated as the incremental cost per QALY gained between MINT Memory Clinics versus usual care. RESULTS: MINT Memory Clinics were found to be less expensive ($C51 496 (95% Crl $C4806 to $C119 367) while slightly improving quality of life (+0.43 (95 Crl 0.01 to 1.24) QALY) compared with usual care. The probabilistic analysis showed that MINT Memory Clinics were the superior treatment compared with usual care 98% of the time. Variation in age was found to have the greatest impact on cost-effectiveness as patients may benefit from the MINT Memory Clinics more if they receive care beginning at a younger age. CONCLUSION: Multispecialty interprofessional memory clinic care is less costly and more effective compared with usual care and early access to care significantly reduces care costs over time. The results of this economic evaluation can inform decision-making and improvements to health system design, resource allocation and care experience for persons living with dementia. Specifically, widespread scaling of MINT Memory Clinics into existing primary care systems may assist with improving quality and access to memory care services while decreasing the growing economic and social burden of dementia.

Identifying the areas of low self-reported confidence of internal medicine residents in geriatrics: a descriptive study of findings from a structured geriatrics skills assessment survey.

BACKGROUND: Currently, no standardized methods exist to assess the geriatric skills and training needs of internal medicine trainees to enable them to become confident in caring for older patients. This study aimed to describe the self-reported confidence and training requirements in core geriatric skills amongst internal medicine residents in Toronto, Ontario using a standardized assessment tool. METHODS: This study used a novel self-rating instrument, known as the Geriatric Skills Assessment Tool (GSAT), among incoming and current internal medicine residents at the University of Toronto, to describe self-reported confidence in performing, teaching and interest in further training with regard to 15 core geriatric skills previously identified by the American Board of Internal Medicine. RESULTS: 190 (75.1%) out of 253 eligible incoming (Year 0) and current internal medicine residents (Years 1-3) completed the GSAT. Year 1-3 internal medicine residents who had completed a geriatric rotation reported being significantly more confident in performing 13/15 (P < 0.001 to P = 0.04) and in teaching 9/15 GSAT skills (P < 0.001 to P = 0.04). Overall, the residents surveyed identified their highest confidence in administering the Mini-Mental Status Examination and lowest confidence in assessing fall risk using a gait and balance tool, and in evaluating and managing chronic pain. CONCLUSION: A structured needs assessment like the GSAT can be valuable in identifying the geriatric training needs of internal medicine trainees based on their reported levels of self-confidence. Residents in internal medicine could further benefit from completing a mandatory geriatric rotation early in their training, since this may improve their overall confidence in providing care for the mostly older patients they will work with during their residency and beyond.

The functional health needs of older persons in custody: A rapid review.

INTRODUCTION: The number of older persons in custody is increasing and older incarcerated individuals have higher functional healthcare needs and higher healthcare costs. Consideration of available measures and interventions to address functional decline, are therefore imperative given the importance of disability to healthcare spending. PURPOSE: To identify the existing literature describing the functional health needs of older incarcerated individuals. METHODS: This rapid review synthesized existing literature on the functional health of older incarcerated individuals. Three electronic databases and two correctional service health-related journals were searched. Bibliographic searches of seminal articles and key authors were conducted for thoroughness. RESULTS: Fifteen articles were retained in the final analysis. The methods of the included studies were heterogenous. Consideration of basic self-care (activities of daily living) and functional mobility were the primary ways of capturing functional health. The concept of 'Prison ADLs' emerged and measured the unique aspects of correction-specific functional activities. CONCLUSIONS: This review identified the existing literature on how the functional health of older incarcerated persons is operationalized and measured, and how it is considered within this unique context. The concept of 'Prison ADLs' provides insight into the functional experiences of this population. Additionally, performance across PADLs typically declines before abilities across traditional ADLs.

Assessment of SARS-CoV-2 Seropositivity During the First and Second Viral Waves in 2020 and 2021 Among Canadian Adults.

Importance: The incidence of infection during SARS-CoV-2 viral waves, the factors associated with infection, and the durability of antibody responses to infection among Canadian adults remain undocumented. Objective: To assess the cumulative incidence of SARS-CoV-2 infection during the first 2 viral waves in Canada by measuring seropositivity among adults. Design, Setting, and Participants: The Action to Beat Coronavirus study conducted 2 rounds of an online survey about COVID-19 experience and analyzed immunoglobulin G levels based on participant-collected dried blood spots (DBS) to assess the cumulative incidence of SARS-CoV-2 infection during the first and second viral waves in Canada. A sample of 19 994 Canadian adults (aged ≥18 years) was recruited from established members of the Angus Reid Forum, a public polling organization. The study comprised 2 phases (phase 1 from May 1 to September 30, 2020, and phase 2 from December 1, 2020, to March 31, 2021) that generally corresponded to the first (April 1 to July 31, 2020) and second (October 1, 2020, to March 1, 2021) viral waves. Main Outcomes and Measures: SARS-CoV-2 immunoglobulin G seropositivity (using a chemiluminescence assay) by major geographic and demographic variables and correlation with COVID-19 symptom reporting. Results: Among 19 994 adults who completed the online questionnaire in phase 1, the mean (SD) age was 50.9 (15.4) years, and 10 522 participants (51.9%) were female; 2948 participants (14.5%) had self-identified racial and ethnic minority group status, and 1578 participants (8.2%) were self-identified Indigenous Canadians. Among participants in phase 1, 8967 had DBS testing. In phase 2, 14 621 adults completed online questionnaires, and 7102 of those had DBS testing. Of 19 994 adults who completed the online survey in phase 1, fewer had an educational level of some college or less (4747 individuals [33.1%]) compared with the general population in Canada (45.0%). Survey respondents were otherwise representative of the general population, including in prevalence of known risk factors associated with SARS-CoV-2 infection. The cumulative incidence of SARS-CoV-2 infection among unvaccinated adults increased from 1.9% in phase 1 to 6.5% in phase 2. The seropositivity pattern was demographically and geographically heterogeneous during phase 1 but more homogeneous by phase 2 (with a cumulative incidence ranging from 6.4% to 7.0% in most regions). The exception was the Atlantic region, in which cumulative incidence reached only 3.3% (odds ratio [OR] vs Ontario, 0.46; 95% CI, 0.21-1.02). A total of 47 of 188 adults (25.3%) reporting COVID-19 symptoms during phase 2 were seropositive, and the OR of seropositivity for COVID-19 symptoms was 6.15 (95% CI, 2.02-18.69). In phase 2, 94 of 444 seropositive adults (22.2%) reported having no symptoms. Of 134 seropositive adults in phase 1 who were retested in phase 2, 111 individuals (81.8%) remained seropositive. Participants who had a history of diabetes (OR, 0.58; 95% CI, 0.38-0.90) had lower odds of having detectable antibodies in phase 2. Conclusions and Relevance: The Action to Beat Coronavirus study found that the incidence of SARS-CoV-2 infection in Canada was modest until March 2021, and this incidence was lower than the levels of population immunity required to substantially reduce transmission of the virus. Ongoing vaccination efforts remain central to reducing viral transmission and mortality. Assessment of future infection-induced and vaccine-induced immunity is practicable through the use of serial online surveys and participant-collected DBS.

Relevance of assessment items in community paramedicine home visit programmes: results of a modified Delphi study.

OBJECTIVE: Guidelines for a structured assessment in community paramedicine home visit programmes have not been established and evidence to inform their creation is lacking. We sought to investigate the relevance of assessment items to the practice of community paramedics according to a pre-established clarity-utility matrix. DESIGN: We designed a modified-Delphi study consisting of predetermined thresholds for achieving consensus, number of rounds of for scoring items, a defined meeting and discussion process, and a sample of participants that was purposefully representative. SETTING AND PARTICIPANTS: We established a panel of 26 community paramedics representing 20 municipal paramedic services in Ontario, Canada. The sample represented a majority of paramedic services within the province that were operating a community paramedicine home visit programme. MEASURES: Drawing from a bank of standardised assessment items grouped according to domains aligned with the International Classification on Functioning, Disability, and Health taxonomy, 64 previously pilot-tested assessment items were scored according to their clarity (being free from ambiguity and easy to understand) and utility (being valued in care planning or case management activities). Assessment items covered a broad range of health, social and environmental domains. To conclude scoring rounds, assessment items that did not achieve consensus for relevance to assessment practices were discussed among participants with opportunities to modify assessment items for subsequent rounds of scoring. RESULTS: Resulting from the first round of scoring, 54 assessment items were identified as being relevant to assessment practices and 3 assessment items were removed from subsequent rounds. The remaining 7 assessment items were modified, with some parts removed from the final items that achieved consensus in the final rounds of scoring. CONCLUSION: A broadly representative panel of community paramedics identified consensus for 61 assessment items that could be included in a structured, multidomain, assessment instrument for guiding practice in community paramedicine home visit programmes.

Impact Analysis of a Pharmacist-Led Home-Medication Review Service Within an interprofessional Outreach Team.

OBJECTIVE: To describe the demographic and clinical characteristics of frail and homebound communitydwelling older patients receiving a home medication review (HMR) conducted by a home-visiting pharmacist; the types of drug therapy problems (DTPs) that were identified; the types of clinical interventions being recommended and their implementation rate. DESIGN: Retrospective, cross-sectional chart-review study using data from patient records. SETTING: Homes of patients receiving a HMR by a community pharmacy-based consulting home-visiting pharmacist. PATIENTS: 171 patients received a HMR between January 1, 2016, and May 31, 2018. INTERVENTION: Patients received a comprehensive HMR by a home-visiting pharmacist working as a member of an interprofessional geriatrics team. MAIN OUTCOME MEASURES: Charlson Comorbidity Index (CCI) score, comorbidities, use of potentially inappropriate medications, DTPs identified, number and type of clinical interventions being recommended and successfully implemented. RESULTS: Patients had a mean age of 81 years (range: 54-100 years), majority were 65 years of age or older (95%), and female (59%). Fifty-three percent of patients had a CCI score of 1 to 2, and 93.6% were experiencing multi-morbidity and polypharmacy. Patients used an average of 13.0 medications, and 76.1% were found to be using at least 1 potentially inappropriate medication. In total, the home-visiting pharmacist identified 827 DTPs and made 1088 recommendations with a successful implementation rate of 74%. CONCLUSIONS: Frail and homebound communitydwelling older adults referred for a HMR were observed to be using a high number of medications with a significant number of DTPs identified. Offering HMRs was an effective method for a community-based pharmacist to make acceptable recommendations to optimize medication therapy management for frail older patients.

Feasibility of Rapidly Developing and Widely Disseminating Patient Decision Aids to Respond to Urgent Decisional Needs due to the COVID-19 Pandemic.

To meet urgent decisional needs of retirement/nursing home residents and their families, our interdisciplinary stakeholder team rapidly developed and disseminated patient decision aids (PtDAs) regarding leaving one's residence during the COVID-19 pandemic. The development steps were as follows: identify urgent decisional needs, develop PtDAs using the Ottawa Decision Support Framework template and minimal International PtDA Standards, obtain stakeholder feedback, broadly disseminate, and incorporate user feedback. Within 2 wk, we developed 2 PtDAs for retirement and nursing home living environments that were informed by decisional needs (identified from public responses to related media reports), current pandemic regulations/guidance, and recent systematic reviews. Within 3 wk of their dissemination (websites, international PtDA inventory, Twitter, Facebook, media interviews), the PtDAs were downloaded 10,000 times, and user feedback was positive. Our expert team showed feasible rapid development and wide dissemination of PtDAs to respond to urgent decisional needs. Development efficiencies included access to a well-tested theory-based PtDA template, recent evidence syntheses, and values-based public responses to media reports. Future research includes methods for rapidly collecting user feedback, facilitating implementation, and measuring use and outcomes.

DIVERT-Collaboration Action Research and Evaluation (CARE) Trial Protocol: a multiprovincial pragmatic cluster randomised trial of cardiorespiratory management in home care.

INTRODUCTION: Home care clients are increasingly medically complex, have limited access to effective chronic disease management and have very high emergency department (ED) visitation rates. There is a need for more appropriate and targeted supportive chronic disease management for home care clients. We aim to evaluate the effectiveness and preliminary cost effectiveness of a targeted, person-centred cardiorespiratory management model. METHODS AND ANALYSIS: The Detection of Indicators and Vulnerabilities of Emergency Room Trips (DIVERT) - Collaboration Action Research and Evaluation (CARE) trial is a pragmatic, cluster-randomised, multicentre superiority trial of a flexible multicomponent cardiorespiratory management model based on the best practice guidelines. The trial will be conducted in partnership with three regional, public-sector, home care providers across Canada. The primary outcome of the trial is the difference in time to first unplanned ED visit (hazard rate) within 6 months. Additional secondary outcomes are to identify changes in patient activation, changes in cardiorespiratory symptom frequencies and cost effectiveness over 6 months. We will also investigate the difference in the number of unplanned ED visits, number of inpatient hospitalisations and changes in health-related quality of life. Multilevel proportional hazard and generalised linear models will be used to test the primary and secondary hypotheses. Sample size simulations indicate that enrolling 1100 home care clients across 36 clusters (home care caseloads) will yield a power of 81% given an HR of 0.75. ETHICS AND DISSEMINATION: Ethics approval was obtained from the Hamilton Integrated Research Ethics Board as well as each participating site's ethics board. Results will be submitted for publication in peer-reviewed journals and for presentation at relevant conferences. Home care service partners will also be informed of the study's results. The results will be used to inform future support strategies for older adults receiving home care services. TRIAL REGISTRATION NUMBER: NCT03012256.

Examining consensus for a standardised patient assessment in community paramedicine home visits: a RAND/UCLA-modified Delphi Study.

OBJECTIVE: Community paramedicine programme are often designed to address repeated and non-urgent use of paramedic services by providing patients with alternatives to the traditional 'treat and transport' ambulance model of care. We sought to investigate the level of consensus that could be found by a panel of experts regarding appropriate health, social and environmental domains that should be assessed in community paramedicine home visit programme. DESIGN: We applied the RAND/UCLA Appropriateness Method in a modified Delphi method to investigate the level of consensus on assessment domains for use in community paramedicine home visit programme. SETTING AND PARTICIPANTS: We included a multi-national panel of 17 experts on community paramedicine and in-home assessment from multiple settings (paramedicine, primary care, mental health, home and community care, geriatric care). MEASURES: A list of potential assessment categories was established after a targeted literature review and confirmed by panel members. Over multiple rounds, panel members scored the appropriateness of 48 assessment domains on a Likert scale from 0 (not appropriate) to 5 (very appropriate). Scores were then reviewed at an in-person meeting and a finalised list of assessment domains was generated. RESULTS: After the preliminary round of scoring, all 48 assessment domains had scores that demonstrated consensus. Nine assessment domains (18.8%) demonstrated a wider range of rated appropriateness. No domains were found to be not appropriate. Achieving consensus about the appropriateness of assessment domains on the first round of scoring negated the need for subsequent rounds of scoring. The in-person meeting resulted in re-grouping assessment domains and adding an additional domain about urinary continence. CONCLUSION: An international panel of experts with knowledge about in-home assessment by community paramedics demonstrated a high level of agreement on appropriate patient assessment domains for community paramedicine home visit programme. Community paramedicine home visit programme are likely to have similar patient populations. A standardised assessment instrument may be viable in multiple settings.

Frailty and Aging: How the Danish Experience Might Inform Canada.

Scandinavian countries are widely acknowledged as leaders in innovative models of care for their aging populations. To learn what might be potentially applicable to the health system in Canada, the Canadian Frailty Network (CFN) led a contingent of government, administrative, research and patient representatives to Denmark to directly observe Danish approaches for providing healthcare for older adults living with frailty. In this paper and based on what we learned from these observations, we discuss healthcare challenges faced by Canada's aging population for which Danish strategies provide clues as to where and how to improve care and system efficiencies, thereby maximizing the value of Canadian healthcare.

Investigating the effect of sociodemographic factors on 30-day hospital readmission among medical patients in Toronto, Canada: a prospective cohort study.

OBJECTIVE: To examine the influence of patient-level sociodemographic factors on the incidence of hospital readmission within 30 days among medical patients in a large Canadian metropolitan city. DESIGN: Prospective cohort study. SETTING AND PARTICIPANTS: Patients admitted to the General Internal Medicine service of an urban teaching hospital in Toronto, Canada participated in a survey of sociodemographic information. Patients were not surveyed if deemed medically unstable, receiving care in medical/surgical step-down beds or were isolated for infection control. Included in the final analysis was a diverse cohort of 1427 adult, non-palliative, patients who were discharged home. MEASURES: Thirteen patient-level sociodemographic variables were examined in relation to time to unplanned all-cause readmission within 30 days. Illness level was accounted for by the following covariates: self-perceived health status, previous hospital utilisation, primary diagnosis case mix group, Charlson Comorbidity Index score and inpatient length of stay. RESULTS: Approximately, 14.4% (n=205) of patients experienced readmission within 30 days. Sociodemographic factors were not significantly associated with time to readmission in unadjusted and adjusted analyses. Indicators of illness level, namely, previous hospitalisations, were the strongest risk factors for readmission within this cohort. One previous admission (adjusted HR 1.78; 95% CI 1.22 to 2.59, P<0.01) and at least four previous emergency department visits (adjusted HR 2.33; 95% CI 1.46 to 4.43, P<0.01) were associated with increased hazard of readmission within 30 days. CONCLUSIONS: Patient-level sociodemographic factors did not influence the incidence of unplanned all-cause readmission within 30 days. Further research is needed to understand the generalisability of our findings and investigate whether contextual factors, such as access to universal health insurance coverage, attenuate the effects of sociodemographic factors.

Impact of an Integrated Hip Fracture Inpatient Program on Length of Stay and Costs.

BACKGROUND: Hip fractures are associated with significant morbidity and mortality. Co-management models pairing orthopaedic surgeons with hospitalists or geriatricians may be effective at improving processes of care and outcomes such as length of stay (LOS) and cost. We set out to determine the effect of an integrated hip fracture co-management model on LOS, cost, and process measures. METHODS: We conducted a single-center pre-post study of 571 patients admitted to an academic medical center with hip fractures between January 2009 and December 2013. The group receiving an integrated medical-surgical co-management incorporating continuous improvement methodology was compared with a control population. Primary outcome was LOS. Secondary outcomes included cost per case, time to surgery, osteoporosis (OP) treatment, preoperative echocardiogram utilization, mortality, and readmission. RESULTS: LOS decreased from 18.2 (1.1) to 11.9 (1.5) days, a reduction of 6.3 days (P < 0.001). Mean cost decreased by $4953 (P < 0.001) per case. Mean time to surgery decreased from 45.8 (66.8) to 29.7 (17.9) hours (P < 0.001). Initiation of OP treatment increased from 55.8% to 96.4% (P < 0.001). Preoperative echocardiogram use decreased from 15.8% to 9.1% (P < 0.05). There was a nonsignificant difference in mortality rate (5.0% vs. 2.1%, P = 0.06). Readmission rate remained unchanged (4.6% vs. 6.0%, P = 0.56). CONCLUSIONS: An integrated medical-surgical co-management model incorporating continuous improvement methodology was associated with reduced LOS, costs, time to surgery, and increased initiation of appropriate OP treatment. LEVEL OF EVIDENCE: Therapeutic Level IV. See Instructions for Authors for a complete description of levels of evidence.

Validity, Reliability and Acceptability of the Team Standardized Assessment of Clinical Encounter Report.

BACKGROUND: The Team Standardized Assessment of a Clinical Encounter Report (StACER) was designed for use in Geriatric Medicine residency programs to evaluate Communicator and Collaborator competencies. METHODS: The Team StACER was completed by two geriatricians and interdisciplinary team members based on observations during a geriatric medicine team meeting. Postgraduate trainees were recruited from July 2010-November 2013. Inter-rater reliability between two geriatricians and between all team members was determined. Internal consistency of items for the constructs Communicator and Collaborator competencies was calculated. Raters completed a survey previously administered to Canadian geriatricians to assess face validity. Trainees completed a survey to determine the usefulness of this instrument as a feedback tool. RESULTS: Thirty postgraduate trainees participated. The prevalence-adjusted bias-adjusted kappa range inter-rater reliability for Communicator and Collaborator items were 0.87-1.00 and 0.86-1.00, respectively. The Cronbach's alpha coefficient for Communicator and Collaborator items was 0.997 (95% CI: 0.993-1.00) and 0.997 (95% CI: 0.997-1.00), respectively. The instrument lacked discriminatory power, as all trainees scored "meets requirements" in the overall assessment. Niney-three per cent and 86% of trainees found feedback useful for developing Communicator and Collaborator competencies, respectively. CONCLUSIONS: The Team StACER has adequate inter-rater reliability and internal consistency. Poor discriminatory power and face validity challenge the merit of using this evaluation tool. Trainees felt the tool provided useful feedback on Collaborator and Communicator competencies.

Integrated client care for frail older adults in the community: preliminary report on a system-wide approach.

The Toronto Central Community Care Access Centre is leading a collaborative local health integration network systemic change initiative to implement and evaluate a practical model of integrated care for older adults with complex needs. The approach is embedded in the community where older adults and their families live and is designed to first and foremost improve the quality of care while ultimately bending the cost curve. The model is leveraging and aligning existing system resources by bringing together sectors from across the health system to create ways of working that build capacity in the system to be more responsive to this population. Outcomes to date will be discussed and next steps described. The secondary goal was to understand the key elements of this integration that can be scaled locally and across the province.

The elder-friendly emergency department assessment tool: development of a quality assessment tool for emergency department-based geriatric care.

OBJECTIVES: To develop and conduct a preliminary validation of selected subscales of an elder-friendly emergency department (ED) assessment tool. DESIGN: Content validation of tool by an international panel. Construct validation using care ratings of ED lead physicians and nurses. SETTING: Quebec, Canada. PARTICIPANTS: The international panel comprised 34 clinicians, administrators, and researchers. The construct validation was based on a 2006 survey of ED lead physicians and nurses at all 103 EDs in the province, of whom 68 (66%) supplied complete data. MEASUREMENTS: The initial tool included five subscales: ED staffing, screening and assessment, discharge planning, community services, and care philosophy. Differences in subscale scores were examined according to ED size, and of these scores were correlated with care ratings made by lead physicians and nurses. RESULTS: The average scores for three subscales (ED staffing, discharge planning, and community services) varied according to ED size. After adjustment for ED size, three subscales (screening and assessment, discharge planning, and community services) were correlated with ED nurse or physician care ratings. A preliminary tool, taking into account all factors, is proposed. CONCLUSION: This study provides preliminary evidence of the validity of three subscales of the proposed elder-friendly ED assessment tool. Results suggest that ED size should be considered in interpreting these subscales. Further evaluation and validation of the proposed tool will be needed to further its utility in helping to focus the quality improvement efforts of clinicians, managers, and administrators related to the care they provide older adults.

Why the elderly could bankrupt Canada and how demographic imperatives will force the redesign of acute care service delivery.

Canada's aging population poses a significant challenge for the existing healthcare system. While individuals 65 and older accounted for 13.7% of the population in 2005, they accounted for 60% of all acute care service spending. This paper further illustrates how the heterogeneity of the older population and its impact on patterns of healthcare use demonstrate the failings of our current care systems. Our outdated acute care models frequently disadvantage the system's highest users, who are often characterized by factors such as poly-morbidity, functional impairment and social frailty. Understanding how implementing innovative models that challenge deeply ingrained ways of providing care has proven to be a significant challenge, this paper highlights one hospital's mission to transform current traditional paradigms of care by developing and implementing an elder-friendly hospital integrated service delivery model. This hospital aims to demonstrate wide-ranging benefits of this model that can contribute toward optimizing the outcomes of hospitalization for older adults and the system as a whole. The establishment of a national agency that could support the development of a national aging strategy to promote best practice dissemination and implementation could also ensure that the significant health, social and economic benefits that better care models can realize could be more easily achieved.
