Impact of an intergenerational program to improve loneliness and social isolation in older adults initiated at the time of emergency department discharge: study protocol for a three-arm randomized clinical trial.

BACKGROUND: Social isolation and loneliness (SIL) worsens mortality and other outcomes among older adults as much as smoking. We previously tested the impact of the HOW R U? intervention using peer support from similar-aged volunteers and demonstrated reduced SIL among older adults discharged from the emergency department (ED). Generativity, defined as "the interest in establishing and guiding the next generation," can provide an alternative theoretical basis for reducing SIL via intergenerational programs between members of younger and older generations. The current protocol will examine the impact of younger intergenerational volunteers providing the HOW RU? METHODS: In this randomized clinical trial, we will compare the following three arms: (1) the standard same-generation peer support HOW R U? intervention, (2) HOW R U? intervention delivered by intergenerational volunteers, and (3) a common wait-list control group. Outcome assessors will be blinded to the intervention. Trained volunteers will deliver 12 weekly telephone support calls. We will recruit participants ≥ 70 years of age with baseline loneliness (six-item De Jong loneliness score of 2 or greater) from two EDs. Research staff will assess SIL, depression, quality of life, functional status, generativity, and perceived benefit at baseline, at 12 weeks, and 24 weeks post-intervention. DISCUSSION: We hypothesize participants receiving the intergenerational intervention will show improved outcomes compared to the control group and peer support HOW R U? INTERVENTION: We also hypothesize that participants with higher perceptions of generativity will have greater reductions in SIL than their lower generativity counterparts. Aging is experienced diversely, and social interventions combatting associated SIL should reflect that diversity. As part of a program of research following the Obesity-Related Behavioral Intervention Trials (ORBIT) model, the findings of this RCT will be used to define which intervention characteristics are most effective in reducing SIL.

Clinical Comorbidities and Transitions Between Care Settings Among Residents of Assisted Living Facilities: A Repeated Cross-Sectional Study.

OBJECTIVE: We investigate the changes in the sociodemographic characteristics, clinical comorbidities, and transitions between care settings among residents of assisted living facilities. DESIGN: Repeated cross-sectional study. SETTING AND PARTICIPANTS: Linked, individual-level health system administrative data on residents of assisted living facilities in Ontario, Canada, from January 1, 2013, to December 31, 2019. METHODS: Counts and proportions were calculated to describe the sociodemographic characteristics and clinical comorbidities. Relative changes and trend tests were calculated to quantify the longitudinal changes in the characteristics of residents of assisted living facilities between 2013 and 2019. A Sankey plot was graphed to display transitions between different care settings (ie, hospital admission, nursing home admission, died, or remained in the assisted living facility) each year from 2013 to 2019. RESULTS: There was a 34% relative increase in the resident population size of assisted living facilities (56,9752019 vs 42,6002013). These older adults had a mean age of 87 years, and women accounted for nearly two-thirds of the population across all years. The 5 clinical comorbidities that had the highest relative increases were renal disease (24.3%), other mental health conditions (16.8%), cardiac arrhythmias (9.6%), diabetes (8.5%), and cancer (6.9%). Nearly 20% of the original cohort from 2013 remained in an assisted living facility at the end of 2019, and approximately 10% of that cohort transitioned to a nursing home in any year from 2013 to 2019. CONCLUSIONS AND IMPLICATIONS: Residents of assisted living facilities are an important older adult population that has progressively increased in clinical complexity within less than a decade. Clinicians and policy makers should advocate for the implementation of on-site medical care that is aligned with the needs of these older adults.

Development and validation of a hospital frailty risk measure using Canadian clinical administrative data.

BACKGROUND: Accessible measures specific to the Canadian context are needed to support health system planning for older adults living with frailty. We sought to develop and validate the Canadian Institute for Health Information (CIHI) Hospital Frailty Risk Measure (HFRM). METHODS: Using CIHI administrative data, we conducted a retrospective cohort study involving patients aged 65 years and older who were discharged from Canadian hospitals from Apr. 1, 2018, to Mar. 31, 2019. We used a 2-phase approach to develop and validate the CIHI HFRM. The first phase, construction of the measure, was based on the deficit accumulation approach (identification of age-related conditions using a 2-year look-back). The second phase involved refinement into 3 formats (continuous risk score, 8 risk groups and binary risk measure), with assessment of their predictive validity for several frailty-related adverse outcomes using data to 2019/20. We assessed convergent validity with the United Kingdom Hospital Frailty Risk Score. RESULTS: The cohort consisted of 788 701 patients. The CIHI HFRM included 36 deficit categories and 595 diagnosis codes that cover morbidity, function, sensory loss, cognition and mood. The median continuous risk score was 0.111 (interquartile range 0.056-0.194, equivalent to 2-7 deficits); 35.1% (n = 277 000) of the cohort were found at risk of frailty (≥ 6 deficits). The CIHI HFRM showed satisfactory predictive validity and reasonable goodness-of-fit. For the continuous risk score format (unit = 0.1), the hazard ratio (HR) for 1-year risk of death was 1.39 (95% confidence interval [CI] 1.38-1.41), with a C-statistic of 0.717 (95% CI 0.715-0.720); the odds ratio for high users of hospital beds was 1.85 (95% CI 1.82-1.88), with a C-statistic of 0.709 (95% CI 0.704-0.714), and the HR of 90-day admission to long-term care was 1.91 (95% CI 1.88-1.93), with a C-statistic of 0.810 (95% CI 0.808-0.813). Compared with the continuous risk score, using a format of 8 risk groups had similar discriminatory ability and the binary risk measure had slightly weaker performance. INTERPRETATION: The CIHI HFRM is a valid tool showing good discriminatory power for several adverse outcomes. The tool can be used by decision-makers and researchers by providing information on hospital-level prevalence of frailty to support system-level capacity planning for Canada's aging population.

Prevalence of preoperative cognitive impairment in older surgical patients.: A systematic review and meta-analysis.

STUDY OBJECTIVE: Older surgical patients with cognitive impairment are at an increased risk for adverse perioperative outcomes, however the prevalence of preoperative cognitive impairment is not well-established within this population. The purpose of this review is to determine the pooled prevalence of preoperative cognitive impairment in older surgical patients. DESIGN: Systematic review and meta-analysis. SETTING: MEDLINE (Ovid), PubMed (non-MEDLINE records only), Embase, Cochrane Central, Cochrane Database of Systematic Reviews, PsycINFO, and EMCare Nursing for relevant articles from 1946 to April 2021. PATIENTS: Patients aged ≥60 years old undergoing surgery, and preoperative cognitive impairment assessed by validated cognitive assessment tools. INTERVENTIONS: Preoperative assessment. MEASUREMENTS: Primary outcomes were the pooled prevalence of preoperative cognitive impairment in older patients undergoing either elective (cardiac or non-cardiac) or emergency surgery. MAIN RESULTS: Forty-eight studies (n = 42,498) were included. In elective non-cardiac surgeries, the pooled prevalence of unrecognized cognitive impairment was 37.0% (95% confidence interval [CI]: 30.0%, 45.0%) among 27,845 patients and diagnosed cognitive impairment was 18.0% (95% CI: 9.0%, 33.0%) among 11,676 patients. Within the elective non-cardiac surgery category, elective orthopedic surgery was analyzed. In this subcategory, the pooled prevalence of unrecognized cognitive impairment was 37.0% (95% CI: 26.0%, 49.0%) among 1117 patients, and diagnosed cognitive impairment was 17.0% (95% CI: 3.0%, 60.0%) among 6871 patients. In cardiac surgeries, the unrecognized cognitive impairment prevalence across 588 patients was 26.0% (95% CI: 15.0%, 42.0%). In emergency surgeries, the unrecognized cognitive impairment prevalence was 50.0% (95% CI: 35.0%, 65.0%) among 2389 patients. CONCLUSIONS: A substantial number of surgical patients had unrecognized cognitive impairment. In elective non-cardiac and emergency surgeries, the pooled prevalence of unrecognized cognitive impairment was 37.0% and 50.0%. Preoperative cognitive screening warrants more attention for risk assessment and stratification.

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.

Evaluation of the Ottawa 3DY as a screening tool for cognitive impairment in older emergency department patients.

OBJECTIVE: This study sought to evaluate the implementation of the Ottawa 3DY Tool, a simple screening instrument for cognitive impairment, by front-line ED clinicians. METHODS: We conducted a prospective cohort study in an academic ED. Patients ≥75 years underwent cognitive screening with the Ottawa 3DY by front-line nurses and physicians. Descriptive statistics were used to describe level of implementation and acceptability of the tool. Sensitivity and specificity was calculated using an Mini-Mental State Exam <25 as the cut-off for cognitive impairment. A weighted kappa was calculated to establish inter-rater agreement. RESULTS: Cognitive screening was completed in 260/332 eligible patients (78.3%), who were 60% female and had a mean age of 83.7 years. Facilitators to screening: perceived importance and ownership of screening and feasibility of Ottawa 3DY. Barriers to screening were: over confidence in clinical judgement and perceived lack of patient benefit. Ottawa 3DY had a sensitivity of 84.6% (64.3-95.0) and specificity of 54.2% (39.3-68.4) when completed by nurses. When completed by emergency physicians, sensitivity was 78.9% (53.9-93.0) and specificity was 70.0% (45.7-87.2). Inter-rater agreement kappa score was 0.67. DISCUSSION: This study demonstrated that incorporating the Ottawa 3DY tool into the routine evaluation of older ED patients by front-line ED clinicians is both feasible and effective. With its demonstrated good inter-rater reliability and moderate level of sensitivity and specificity when compared with the much longer MMSE, the routine adoption of this tool may help lead to improved recognition of cognitive impairment and ultimately patient and system outcomes.

Standard set of health outcome measures for older persons.

BACKGROUND: The International Consortium for Health Outcomes Measurement (ICHOM) was founded in 2012 to propose consensus-based measurement tools and documentation for different conditions and populations.This article describes how the ICHOM Older Person Working Group followed a consensus-driven modified Delphi technique to develop multiple global outcome measures in older persons. The standard set of outcome measures developed by this group will support the ability of healthcare systems to improve their care pathways and quality of care. An additional benefit will be the opportunity to compare variations in outcomes which encourages and supports learning between different health care systems that drives quality improvement. These outcome measures were not developed for use in research. They are aimed at non researchers in healthcare provision and those who pay for these services. METHODS: A modified Delphi technique utilising a value based healthcare framework was applied by an international panel to arrive at consensus decisions.To inform the panel meetings, information was sought from literature reviews, longitudinal ageing surveys and a focus group. RESULTS: The outcome measures developed and recommended were participation in decision making, autonomy and control, mood and emotional health, loneliness and isolation, pain, activities of daily living, frailty, time spent in hospital, overall survival, carer burden, polypharmacy, falls and place of death mapped to a three tier value based healthcare framework. CONCLUSIONS: The first global health standard set of outcome measures in older persons has been developed to enable health care systems improve the quality of care provided to older persons.

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.

Screening for Frailty in Canada's Health Care System: A Time for Action.

As Canada's population ages, frailty - with its increased risk of functional decline, deterioration in health status, and death - will become increasingly common. The physiology of frailty reflects its multisystem, multi-organ origins. About a quarter of Canadians over age 65 are frail, increasing to over half in those older than 85. Our health care system is organized around single-organ systems, impairing our ability to effectively treat people having multiple disorders and functional limitations. To address frailty, we must recognize when it occurs, increase awareness of its significance, develop holistic models of care, and generate better evidence for its treatment. Recognizing how frailty impacts lifespan will allow for integration of care goals into treatment options. Different settings in the Canadian health care system will require different strategies and tools to assess frailty. Given the magnitude of challenges frailty poses for the health care system as currently organized, policy changes will be essential.
