AbstractObjectives Delayed discharge, remaining in acute care longer than medically necessary, reflects less than optimal use of hospital care resources and can have negative implications for patients. We studied (1) the change over time in delayed discharge in people with and without dementia, and (2) the association of delayed discharge with discharge destination and with the continuity of primary care prior to urgent admission. Design A retrospective population-based study. Setting and Participants Delayed discharge after urgent admission and length of delayed discharge were studied in all hospital users aged ≥70 years with at least 1 urgent admission in British Columbia, Canada, in years 2001/02, 2005/06, 2010/11, and 2015/16 (N = 276,299). Methods Linked administrative data provided by Population Data BC were analyzed using generalized estimating equations (GEE), logistic regression analysis, and negative binomial regression analyses. Results Delayed discharge increased among people with dementia and decreased among people without dementia, whereas the length of delay decreased among both. Dementia was the strongest predictor of delayed discharge [odds ratio 4.76; 95% confidence interval (CI) 4.59–4.93], whereas waiting for long-term care placement [incidence rate ratio (IRR) 1.56; 95% CI 1.50–1.62] and dementia (IRR 1.50; 95% CI 1.45–1.54) predicted a higher number of days of delay. Continuity and quantity of care with the same physician before urgent admission was associated with a decreased risk of delayed discharge, especially in people with dementia. Conclusions and Implications This study demonstrates the need for better system integration and patient-centered care especially for people with dementia. Population aging will likely increase the number of patients at risk of delayed discharge. Delayed discharge is associated with both the patient's complex needs and the inability of the system to meet these needs during and after urgent care. Sufficient investments are needed in both primary care and long-term care resources to reduce delayed discharges.

Reduced use of the emergency department during the COVID-19 pandemic may result in increased disease acuity when patients do seek health care services. We sought to evaluate emergency department visits for common abdominal and gynecologic conditions before and at the beginning of the pandemic to determine whether changes in emergency department attendance had serious consequences for patients.We conducted a population-based analysis using administrative data to evaluate the weekly rate of emergency department visits pre-COVID-19 (Jan. 1-Mar. 10, 2020) and during the beginning of the COVID-19 pandemic (Mar. 11-June 30, 2020), compared with a historical control period (Jan. 1-July 1, 2019). All residents of Ontario, Canada, presenting to the emergency department with appendicitis, cholecystitis, ectopic pregnancy or miscarriage were included. We evaluated weekly incidence rate ratios (IRRs) of emergency department visits, management strategies and clinical outcomes.Across all study periods, 39 691 emergency department visits met inclusion criteria (40.2 % appendicitis, 32.1% miscarriage, 21.3% cholecystitis, 6.4% ectopic pregnancy). Baseline characteristics of patients presenting to the emergency department did not vary across study periods. After an initial reduction in emergency department visits, presentations for cholecystitis and ectopic pregnancy quickly returned to expected levels. However, presentations for appendicitis and miscarriage showed sustained reductions (IRR 0.61-0.80), with 1087 and 984 fewer visits, respectively, after the start of the pandemic, relative to 2019. Management strategies, complications and mortality rates were similar across study periods for all conditions.Although our study showed evidence of emergency department avoidance in Ontario during the first wave of the COVID-19 pandemic, no adverse consequences were evident. Emergency care and outcomes for patients were similar before and during the pandemic.

BACKGROUND: The epidemiology of SARS-CoV-2 infection in retirement homes (also known as assisted living facilities) is largely unknown. We examined the association between home-and community-level characteristics and the risk of outbreaks of SARS-CoV-2 infection in retirement homes since the beginning of the first wave of the COVID-19 pandemic. METHODS: We conducted a population-based, retrospective cohort study of licensed retirement homes in Ontario, Canada, from Mar. 1 to Dec. 18, 2020. Our primary outcome was an outbreak of SARS-CoV-2 infection (≥ 1 resident or staff case confirmed by validated nucleic acid amplification assay). We used time-dependent proportional hazards methods to model the associations between retirement home– and community-level characteristics and outbreaks of SARS-CoV-2 infection. RESULTS: Our cohort included all 770 licensed retirement homes in Ontario, which housed 56 491 residents. There were 273 (35.5%) retirement homes with 1 or more outbreaks of SARS-CoV-2 infection, involving 1944 (3.5%) residents and 1101 staff (3.0%). Cases of SARS-CoV-2 infection were distributed unevenly across retirement homes, with 2487 (81.7%) resident and staff cases occurring in 77 (10%) homes. The adjusted hazard of an outbreak of SARS-CoV-2 infection in a retirement home was positively associated with homes that had a large resident capacity, were co-located with a long-term care facility, were part of larger chains, offered many services onsite, saw increases in regional incidence of SARS-CoV-2 infection, and were located in a region with a higher community-level ethnic concentration. INTERPRETATION: Readily identifiable characteristics of retirement homes are independently associated with outbreaks of SARS-CoV-2 infection and can support risk identification and priority for vaccination.

Background Countries worldwide are experiencing a third wave of the coronavirus disease 2019 (COVID-19) pandemic. Government-imposed restrictive measures continue with undetermined effects on physical and mental health. Aims To compare child and adolescent mental health services (CAMHS) referrals over 11 months (January–November) in 2020, 2019 and 2018 and examine any impact the different phases of the COVID-19 restrictions might have on referral rates. Method Monthly CAMHS Health Service Executive data were examined, covering a catchment population of 260 560 or 12.7% of all youth (age group 0–18 years) in Ireland. The total number of urgent and routine referrals, appointments offered, rates of non-attendances and discharge outcome are presented. Results There was a significant drop in referrals in 2020, compared with prior years (χ2 = 10.3, d.f. = 2, P = 0.006). Referrals in 2020 dropped from March to May by 11% and from June to August by 10.3%. From September, both routine and urgent referrals increased by 50% compared with previous years (2018/2019), with the highest increase in November 2020 (180%). Clinic activity also increased from September, with double the number of out-patient appointments offered, compared with previous years (χ2 = 5171.72, d.f. = 3, P < 0.001) and lower (6.6%) rates of non-attendance (χ2 = 868.35, d.f. = 3, P < 0.001). Conclusions In 2020, following an initial decline, referrals to CAMHS increased consistently from September. Such unprecedented increase in referrals places further strain on services that are already underresourced and underfunded, with the likelihood of increased waiting lists post COVID-19. It is envisaged that once the pandemic is over, resources will be even more constrained, and CAMHS will be urgently in need of additional ring-fenced funding.

The coronavirus disease 2019 (COVID-19) pandemic has severely affected nursing homes. Vulnerable nursing home residents are at high risk for adverse outcomes, but improved understanding is needed to identify risk factors for mortality among nursing home residents.To identify risk factors for 30-day all-cause mortality among US nursing home residents with COVID-19.This cohort study was conducted at 351 US nursing homes among 5256 nursing home residents with COVID-19-related symptoms who had severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection confirmed by polymerase chain reaction testing between March 16 and September 15, 2020.Resident-level characteristics, including age, sex, race/ethnicity, symptoms, chronic conditions, and physical and cognitive function.Death due to any cause within 30 days of the first positive SARS-CoV-2 test result.The study included 5256 nursing home residents (3185 women [61%]; median age, 79 years [interquartile range, 69-88 years]; and 3741 White residents [71%], 909 Black residents [17%], and 586 individuals of other races/ethnicities [11%]) with COVID-19. Compared with residents aged 75 to 79 years, the odds of death were 1.46 (95% CI, 1.14-1.86) times higher for residents aged 80 to 84 years, 1.59 (95% CI, 1.25-2.03) times higher for residents aged 85 to 89 years, and 2.14 (95% CI, 1.70-2.69) times higher for residents aged 90 years or older. Women had lower risk for 30-day mortality than men (odds ratio [OR], 0.69 [95% CI, 0.60-0.80]). Two comorbidities were associated with mortality: diabetes (OR, 1.21 [95% CI, 1.05-1.40]) and chronic kidney disease (OR, 1.33 [95%, 1.11-1.61]). Fever (OR, 1.66 [95% CI, 1.41-1.96]), shortness of breath (OR, 2.52 [95% CI, 2.00-3.16]), tachycardia (OR, 1.31 [95% CI, 1.04-1.64]), and hypoxia (OR, 2.05 [95% CI, 1.68-2.50]) were also associated with increased risk of 30-day mortality. Compared with cognitively intact residents, the odds of death among residents with moderate cognitive impairment were 2.09 (95% CI, 1.68-2.59) times higher, and the odds of death among residents with severe cognitive impairment were 2.79 (95% CI, 2.14-3.66) times higher. Compared with residents with no or limited impairment in physical function, the odds of death among residents with moderate impairment were 1.49 (95% CI, 1.18-1.88) times higher, and the odds of death among residents with severe impairment were 1.64 (95% CI, 1.30-2.08) times higher.In this cohort study of US nursing home residents with COVID-19, increased age, male sex, and impaired cognitive and physical function were independently associated with mortality. Understanding these risk factors can aid in the development of clinical prediction models of mortality in this population.

COVID-19 pandemic has boosted telemedicine in medical clinical practice. Experiences in the management of chronic neurological disorders are limited and scattered. The aim of the study was to evaluate feasibility and efficacy of virtual visit for chronic neurological disorders during COVID-19 pandemic. All patients scheduled for a visit during the lockdown period were contacted. The patients fell into four categories: (1) long-term follow-up, the patient was re-scheduled; (2) visit was necessary, teleconsultation was accepted; (3) problem was solved by phone call; and (4) visit was necessary and teleconsultation was not feasible, then visit was maintained. Google Meet was used. During the virtual visit, neurological examination was performed, and demographic and clinical characteristics were recorded. At the end of May 2020, 184 virtual visits for 178 patients were performed for the following diseases: myasthenia gravis (47 patients), multiple sclerosis (79), epilepsy (12), headache (6), and parkinsonism (34). The patients were 70 males and 108 females with a mean age of 53.5 years (range 13–90). During virtual visit, we were able to obtain a satisfactory neurological examination. We demonstrated feasibility and effectiveness of virtual visit in the management of a large group of patients with common chronic neurological disorders.

Background: The coronavirus disease 2019 (COVID-19) pandemic has negatively affected the mental health of the general population. Objective: We investigated the determinants of quality of life (QOL) in Parkinson’s disease (PD) patients during the COVID-19 pandemic. Methods: Impacts of lifestyle changes due to the COVID-19 pandemic on 100 patients with PD and their caregivers/spouses were assessed. The Hospital Anxiety and Depression Scale was used to assess anxiety and depression. The physical component summary (PCS) and mental component summary (MCS) scores of the short form (SF)-8 were used to evaluate health-related QOL. Results: Regarding health-related QOL, physical function, role physical, general health, vitality and the PCS score were significantly worse in PD patients than in caregivers. Worsening of PD-related symptoms, increased stress, and decreased physical activity were observed in 29.0%, 37.0% and 44.0% of PD patients, respectively. Sixteen patients (16.0%) experienced problems with hospital access, but none reported medication shortages. Strong concerns about COVID-19 were reported by 47.0% of caregivers and 50.0% of PD patients. In PD patients, increased gait disturbance and rigidity, disease severity, smoking, the levodopa equivalent dose and decreased body weight predicted a worse PCS score; anxiety, depression, female sex, stress and long disease duration predicted a worse MCS score. In caregivers, age and smoking contributed to a worse PCS score; depression, stress and worsening patient mood contributed to a worse MCS score. Conclusion: We report the negative impacts of the COVID-19 pandemic on health-related QOL and its determinants in PD patients and their caregivers.

ObjectiveAccess to health services and adequate care is influenced by sex, ethnicity, socioeconomic position (SEP) and the burden of comorbidities. Our study aimed to assess whether the COVID-19 pandemic further deepened these already existing health inequalities.DesignCross-sectional study.SettingData were collected from five longitudinal age-homogenous British cohorts (born in 2000-2002, 1989-1990, 1970, 1958 and 1946).ParticipantsA web survey was sent to the cohorts. Anybody who responded to the survey was included, resulting in 14 891 eligible participants.Main outcomes measuredThe survey provided data on cancelled surgical or medical appointments, and the number of care hours received in a week during the first UK COVID-19 national lockdown.InterventionsUsing binary or ordered logistic regression, we evaluated whether these outcomes differed by sex, ethnicity, SEP and having a chronic illness. Adjustment was made for study design, non-response weights, psychological distress, presence of children or adolescents in the household, COVID-19 infection, key worker status, and whether participants had received a shielding letter. Meta-analyses were performed across the cohorts, and meta-regression was used to evaluate the effect of age as a moderator.ResultsWomen (OR 1.40, 95% CI 1.27 to 1.55) and those with a chronic illness (OR 1.84, 95% CI 1.65 to 2.05) experienced significantly more cancellations during lockdown (all p<0.0001). Ethnic minorities and those with a chronic illness required a higher number of care hours during the lockdown (both OR≈2.00, all p<0.002). SEP was not associated with cancellation or care hours. Age was not independently associated with either outcome in the meta-regression.ConclusionThe UK government’s lockdown approach during the COVID-19 pandemic appears to have deepened existing health inequalities, impacting predominantly women, ethnic minorities and those with chronic illnesses. Public health authorities need to implement urgent policies to ensure equitable access to health and care for all in preparation for a fourthwave.

Improved therapeutics and supportive care in hospitals have helped reduce mortality from COVID-19. However, there is limited evidence as to whether nursing home residents, who account for a disproportionate share of COVID-19 deaths and are often managed conservatively in the nursing home instead of being admitted to the hospital, have experienced similar mortality reductions. In this study we examined changes in thirty-day mortality rates between March and November 2020 among 12,271 nursing home residents with COVID-19. We found that adjusted mortality rates significantly declined from a high of 20.9 percent in early April to 11.2 percent in early November. Mortality risk declined for residents with both symptomatic and asymptomatic infections and for residents with both high and low clinical complexity. The mechanisms driving these trends are not entirely understood, but they may include improved clinical management within nursing homes, improved personal protective equipment supply and use, and genetic changes in the virus.

BACKGROUND: Globally, primary care changed dramatically as a result of the coronavirus disease 2019 (COVID-19) pandemic. We aimed to understand the degree to which office and virtual primary care changed, and for which patients and physicians, during the initial months of the pandemic in Ontario, Canada. METHODS: This population-based study compared comprehensive, linked primary care physician billing data from Jan. 1 to July 28, 2020, with the same period in 2019. We identified Ontario residents with at least 1 office or virtual (telephone or video) visit during the study period. We compared trends in total physician visits, office visits and virtual visits before COVID-19 with trends after pandemic-related public health measures changed the delivery of care, according to various patient and physician characteristics. We used interrupted time series analysis to compare trends in the early and later halves of the COVID-19 period. RESULTS: Compared with 2019, total primary care visits between March and July 2020 decreased by 28.0%, from 7.66 to 5.51 per 1000 people/day. The smallest declines were among patients with the highest expected health care use (8.3%), those who could not be attributed to a primary care physician (10.2%), and older adults (19.1%). In contrast, total visits in rural areas increased by 6.4%. Office visits declined by 79.1% and virtual care increased 56-fold, comprising 71.1% of primary care physician visits. The lowest uptake of virtual care was among children (57.6%), rural residents (60.6%) and physicians with panels of ≥ 2500 patients (66.0%). INTERPRETATION: Primary care in Ontario saw large shifts from office to virtual care over the first 4 months of the COVID-19 pandemic. Total visits declined least among those with higher health care needs. The determinants and consequences of these major shifts in care require further study.

ObjectiveTo assess the trends in visits, overall and by age, to urban and non-urban emergency departments (EDs), and visits resulting in admission to hospital before and during the COVID-19 pandemic using a large regional database.SettingA large regional database of 28 EDs during the COVID-19 pandemic in Michigan, with an index case of 11 March 2020 and peak in the first week of April.ParticipantsED visits during the first 5 months of the calendar year were included and compared with the previous year. Facilities where these participants were seen were classified as urban or non-urban, with comparisons of total visits, COVID-like cases, paediatric and trauma.Outcome measuresDaily visits to EDs of patients presenting with COVID-like symptoms, trauma, age patterns and total cases, and stratified between urban and non-urban settings.ResultsThere were 1 732 852 visits across the 2 years, 953 407 between study and comparison periods, and 457 130 visits defined as COVID-like (median age 44 years). Total ED visits decreased to 48% of the previous year, showing a delayed-inverse relationship with COVID-19. Trauma cases dropped but returned to the pre-COVID-19 rate by the end of May in Urban centres. Paediatric cases decreased to 20% of the previous year by the end of April. The oldest age groups showed the least change in ED visits in response to the pandemic.ConclusionsThis large US Midwestern state study describes a dramatic decrease in ED visits after the onset of the COVID-19 pandemic in Michigan, including stratification by varying ages and trauma, demonstrating the tangible impact of the COVID-19 pandemic on urban and non-urban EDs.

The coronavirus disease 2019 (COVID-19) pandemic has critically affected healthcare delivery in the United States. Little is known on its impact on the utilization of emergency department (ED) services, particularly for conditions that might be medically urgent. The objective of this study was to explore trends in the number of outpatient (treat and release) ED visits during the COVID-19 pandemic.We conducted a cross-sectional, retrospective study of outpatient emergency department visits from January 1, 2019 to August 31, 2020 using data from a large, urban, academic hospital system in Utah. Using weekly counts and trend analyses, we explored changes in overall ED visits, by patients' area of residence, by medical urgency, and by specific medical conditions.While outpatient ED visits were higher (+6.0%) in the first trimester of 2020 relative to the same period in 2019, the overall volume between January and August of 2020 was lower (-8.1%) than in 2019. The largest decrease occurred in April 2020 (-30.4%), followed by the May to August period (-12.8%). The largest declines were observed for visits by out-of-state residents, visits classified as non-emergent, primary care treatable or preventable, and for patients diagnosed with hypertension, diabetes, headaches and migraines, mood and personality disorders, fluid and electrolyte disorders, and abdominal pain. Outpatient ED visits for emergent conditions, such as palpitations and tachycardia, open wounds, syncope and collapse remained relatively unchanged, while lower respiratory disease-related visits were 67.5% higher in 2020 relative to 2019, particularly from March to April 2020. However, almost all types of outpatient ED visits bounced back after May 2020.Overall outpatient ED visits declined from mid-March to August 2020, particularly for non-medically urgent conditions which can be treated in other more appropriate care settings. Our findings also have implications for insurers, policymakers, and other stakeholders seeking to assist patients in choosing more appropriate setting for their care during and after the pandemic.

Home care aides are on the frontlines providing care to vulnerable individuals in their homes during the COVID-19 pandemic yet are often excluded from policies to protect health care workers. The goal of this study was to examine experiences of agency-employed home care aides during the COVID-19 pandemic and to identify ways to mitigate concerns. We used an innovative journaling approach with thirty-seven aides as well as in-depth interviews with fifteen aides and leadership representatives from nine home health agencies in New York and Michigan. Workers described a range of concerns around workplace safety including uncertainty around whether a client had COVID-19, inadequate access to personal protective equipment and safe transportation, as well as fundamental changes to interactions with clients. Agencies also faced challenges acquiring personal protective equipment for their aides. This research points to needed resources to support home care aides and home health agencies both during a public health crisis and in the future.

Abstract Background The transition from hospital to primary care is a risk factor for negative health outcomes in people with cognitive impairment. Objective To test the effectiveness of intersectoral care management during the transition from hospital to primary care on repeated admission to hospital, functionality and institutionalisation in people with cognitive impairment. Design Longitudinal multisite randomised controlled trial with two arms (care as usual and intersectoral care management) and two follow-ups 3 and 12 months after discharge. Setting Three hospitals in two different primary care regions in Germany. Subjects n = 401 people with cognitive impairment: community-dwelling, age 70+. Randomised into control (n = 192) or intervention (n = 209). Methods Primary outcomes for the study after 3 months: admission to hospital, physical and instrumental functionality. Primary outcome after 12 months: institutionalisation, physical and instrumental functionality. Secondary outcomes: health-related quality of life, depressive symptoms, cognitive status and frailty. Statistical analyses include descriptive analyses as well as univariate and multivariate regression models for all outcomes. Results There was no statistically significant effect of the intervention on hospital admission and activities of daily living after 3 months, as well as on institutionalisation and activities of daily living after 12 months. There were significantly fewer participants in the intervention group readmitted to the hospital 12 months after discharge. Analyses show a significant effect on health-related quality of life 3 months and 12 months after discharge. Depressive symptoms were significantly less likely in the intervention group 3 months after discharge. No effects on cognition or frailty. Conclusion Intersectoral care management supports people with cognitive impairment during discharge and transition. Even though we were not able to show an impact of the intervention on the chosen primary outcomes everyday functionality and institutionalisation, the effects on health-related quality of life, hospital admission rate and mental health are solid indicators for an improved individual situation.

This article seeks to advance our understanding of the care experiences of people living with the effects of disability, ageing and other social locations during the COVID-19 pandemic. Drawing on key informant interviews (n = 8) and results from an anonymous online survey (n = 36), this article provides evidence of how people with disabilities and older adults in Ontario, Canada, experienced disruptions in different types of care in their multiple caring relationships. The results describe why they were not able to access the care that they needed during a period when activities began to resume and how their caring relationships had been disrupted. The impact of disruption on people with disabilities, older adults and others in their care relationships was exacerbated by barriers rooted in ableism, ageism and other forms of exclusion. This study demonstrates the importance of addressing unmet care needs by moving beyond the dichotomy of ‘carer’ and ‘cared for’.

Virtual care (VC) for dementia in primary care settings is an important aspect of healthcare delivery in Canada. However, the evidence informing optimal and sustainable provision of VC for persons living with dementia (PLWD) and their care partners is scarce. The objectives of this study were to (1) describe the frequency of VC use, (2) identify characteristics of PLWD, care partners, and family physicians (FPs) that are associated with the use of VC, and (3) explore FPs’ perceptions of barriers and facilitators to provide VC for PLWD and their care partners. The Alzheimer Society of Canada and College of Family Physicians of Canada conducted three nationwide cross-sectional surveys between October 2020 and April 2021: (1) One with PLWD, (2) one with care partners of PLWD, and (3) one with FPs. Virtual care was defined as two-way synchronous communication by telephone and/or a web camera. The prevalence of VC use among FPs, PLWD, and care partners was described. Logistic regression models were used to determine characteristics of participants (sociodemographic, urbanicity, frequency and availability of support for connecting with FPs, and FPs’ practice characteristics) associated with any VC use (phone and/or video). Inductive thematic analysis of open-ended questions explored FPs’ perceptions. 131 PLWD, 341 care partners, and 125 FPs participated. 61.2% of PLWD, 59.5% of care partners, and 77.4% of FPs reported using VC. The models for PLWD (included age and ethnicity) and care partners (included gender/sex, urbanicity, and receiving support from a family member/friend to connect with FP) were inconclusive. FPs with > 20 years in practice were less likely to provide VC (OR = 0.23, 95%CI: 0.08–0.62, p < 0.01). FPs perceived that preferences regarding virtual vs. in-person care, office/family support, technology and family presence, and remuneration for FPs influenced VC use. Virtual primary dementia care uptake in Canada is substantial and mainly performed via telephone. According to FPs, physician-patient-caregiver partnerships and infrastructure for VC play key roles in using VC. Virtual care could facilitate access to primary care and minimize potential disruptions to in-person care for PLWD. Outcomes of virtual primary care for dementia need further investigation.

During the initial wave of coronavirus disease of 2019 (COVID-19), patients were rapidly discharged from acute hospitals in anticipation of an expected influx of patients with COVID-19. Patients that were no longer receiving acute medical care but were waiting for their next destination (i.e., delayed hospital discharge) were particularly affected. The objectives of this study were to examine the impact of COVID-19 onset on healthcare utilization and mortality among those who experienced delayed discharge from acute care. We conducted a population-based retrospective cohort study using linked administrative data. We included persons discharged from acute care who experienced a delayed hospital stay between April 1, 2019 and September 30, 2020. The onset of COVID-19 was the exposure (March 1, 2020), while the period of April 1, 2019 to February 29, 2020 was considered as a comparator. Primary outcomes included healthcare utilization and mortality following discharge, stratified by care setting (homecare, inpatient rehabilitation or long-term care). Multivariable logistic, zero-inflated Poisson regressions, and Cox proportional hazard models were used to examine the impact of COVID-19 on outcomes while adjusting for covariates. Those discharged home were more likely to receive homecare and physician visits within 30 days during COVID-19. The type of visits examined included both in-person as well as virtual visits. Individuals discharged to inpatient rehabilitation experienced lower rates of general physician visits but higher rates of specialist and homecare visits. Patients discharged to long-term care were significantly less likely to receive a physician visit following COVID-19, and significantly more likely to be readmitted within 7-days. There were no significant differences in mortality irrespective of discharge destination during the two time periods. Overall, the onset of the initial wave of COVID-19 significantly impacted healthcare utilization among those with a delayed discharge but varied depending on destination, with those in long-term care being most impacted.

Background Adult day programs provide critical supports to older adults and their family or friend caregivers. High-quality care in the community for as long as possible and minimizing facility-based continuing care are key priorities of older adults, their caregivers, and health care systems. While most older adults in need of care live in the community, about 10% of newly admitted care home residents have relatively low care needs that could be met in the community with the right supports. However, research on the effects of day programs is inconsistent. The methodological quality of studies is poor, and we especially lack robust, longitudinal research. Objective Our research objectives are to (1) compare patterns of day program use (including nonuse) by province (Alberta, British Columbia, and Manitoba) and time; (2) compare characteristics of older adults by day program use pattern (including nonuse), province, and time; and (3) assess effects of day programs on attendees, compared with a propensity score–matched cohort of older nonattendees in the community. Methods In this population-based retrospective cohort study, we will use clinical and health administrative data of older adults (65+ years of age) who received publicly funded continuing care in the community in the Canadian provinces of Alberta, British Columbia, and Manitoba between January 1, 2012, and December 31, 2024. We will compare patterns of day program use between provinces and assess changes over time. We will then compare characteristics of older adults (eg, age, sex, physical or cognitive disability, area-based deprivation indices, and caregiver availability or distress) by pattern of day program use or nonuse, province, and time. Finally, we will create a propensity score–matched comparison group of older adults in the community, who have not attended a day program. Using time-to-event models and general estimating equations, we will assess whether day program attendees compared with nonattendees enter care homes later; use emergency, acute, or primary care less frequently; experience less cognitive and physical decline; and have better mental health. Results This will be a 3-year study (July 1, 2024, to June 30, 2027). We received ethics approvals from the relevant ethics boards. Starting on July 1, 2024, we will work with the 3 provincial health systems on data access and linkage, and we expect data analyses to start in early 2025. Conclusions This study will generate robust Canadian evidence on the question whether day programs have positive, negative, or no effects on various older adult and caregiver outcomes. This will be a prerequisite to improving the quality of care provided to older adults in day programs, ultimately improving the quality of life of older adults and their caregivers.

Background COVID-19 and resulting health system and policy decisions led to significant changes in healthcare use by nursing homes (NH) residents. It is unclear whether healthcare outcomes were similarly affected among older adults in assisted living (AL). This study compared hospitalization events in AL and NHs during COVID-19 pandemic waves 1 through 4, relative to historical periods. Methods This was a population-based, repeated cross-sectional study using linked clinical and health administrative databases (January 2018 to December 2021) for residents of all publicly subsidized AL and NH settings in Alberta, Canada. Setting-specific monthly cohorts were derived for pandemic (starting March 1, 2020) and comparable historical (2018/2019 combined) periods. Monthly rates (per 100 person-days) of all-cause hospitalization, hospitalization with delayed discharge, and hospitalization with death were plotted and rate ratios (RR) estimated for period (pandemic wave vs historical comparison), setting (AL vs NH) and period-setting interactions, using Poisson regression with generalized estimating equations, adjusting for resident and home characteristics. Results On March 1, 2020, there were 9,485 AL and 14,319 NH residents, comparable in age (mean 81 years), sex (>60% female) and dementia prevalence (58–62%). All-cause hospitalization rates declined in both settings during waves 1 (AL: adjusted RR 0.60, 95%CI 0.51–0.71; NH: 0.74, 0.64–0.85) and 4 (AL: 0.76, 0.66–0.88; NH: 0.65, 0.56–0.75) but unlike NHs, AL rates were not significantly lower during wave 2 (and increased 27% vs NH, January 2021). Hospitalization with delayed discharge increased in NHs only (during and immediately after wave 1). Both settings showed a significant increase in hospitalization with death in wave 2, this increase was larger and persisted longer for AL. Conclusions Pandemic-related changes in hospitalization events differed for AL and NH residents and by wave, suggesting unique system and setting factors driving healthcare use and outcomes in these settings in response to this external stress.

In Ontario, despite the increasing prevalence of Parkinson’s disease (PD), barriers to access-to-care for people with Parkinson’s disease (PwP) and their caregivers are not well understood. The objective of this study is to examine spatial patterns of health care utilization among PwP and identify factors associated with PD-related health care utilization of individuals in Ontario. We employed a retrospective, population-based study design involving administrative health data to identify PwP as of March 31, 2018 (N = 35,482) using a previously validated case definition. An enhanced 2-step floating catchment area method was used to measure spatial accessibility to PD care and a descriptive spatial analysis was conducted to describe health service utilization by geographic area and specialty type. Negative binomial regression models were then conducted to identify associated geographic, socioeconomic, comorbidity and demographic factors. There was marked spatial variability in PD-related service utilization, with neurology and all provider visits being significantly higher in urban areas (CMF>1.20; p<0.05) and family physician visits being significantly higher (CMF >1.20; p<0.05) in more rural areas and remote areas. More frequent visits to family physicians were associated with living in rural areas, while less frequent visitation was associated with living in areas of low spatial accessibility with high ethnic concentration. Visits to neurologists were positively associated with living in areas of high spatial accessibility and with high ethnic concentration. Visits to all providers were also positively associated with areas of high spatial accessibility. For all outcomes, less frequent visits were found in women, older people, and those living in more deprived areas as years living with PD increased. This study demonstrates the importance of geographic, socioeconomic and individual factors in determining PwP’s likelihood of accessing care and type of care provided. Our results can be expected to inform the development of policies and patient care models aimed at improving accessibility among diverse populations of PwP.

BackgroundAlthough several studies have documented the detrimental impacts of global COVID-19 containment measures on individuals with Alzheimer's disease and dementia, a comprehensive analysis of mortality rates for these conditions within the Chilean population is notably lacking. This study aimed to analyze the impact of COVID-19 on mortality rates among individuals with dementia and Alzheimer's disease in Chile.MethodsA retrospective longitudinal cross-sectional study was conducted, considering mortality data for specific mental health conditions during the pre-pandemic and pandemic contexts of COVID-19 in Chile. Quantile regression techniques were employed to analyze the existence of differences between the two periods, while non-observable heterogeneity models for panel data methods were used to evaluate the effect of COVID-19 mortality on crude mortality rates.FindingsStatistically significant differences were observed in the number of deaths from dementia and Alzheimer's disease between the pre-pandemic and COVID-19 pandemic periods. Specifically, crude mortality rates decreased by 10% (−0.10 [95% CI: −0.16, −0.05]) during the pandemic period. Furthermore, the number of deaths from COVID-19 during the pandemic period has a very weak incidence of deaths from mental health conditions such as dementia and Alzheimer's. Specifically, a unit percentage increase in confirmed cases from COVID-19 would result in a 7% (−0.07 [95% CI: −0.13, −0.001]) decrease in the number of deaths from dementia and Alzheimer's. These findings are supported by the application of panel regression with one-way random effects models.InterpretationThe study findings indicate a reduction in mortality rates attributed to dementia and Alzheimer's disease during the COVID-19 pandemic in Chile. This decline could be attributed to the potential underreporting of mental illness as the cause of death during the pandemic period. Several studies have highlighted that approximately 30% of death certificates fail to document the presence of a dementia syndrome. Moreover, the cause of death recorded for individuals with mental health conditions may be influenced by the physician's familiarity with the patient or reflect the prevailing approach to managing end-stage dementia patients.FundingThis work received no funding.

Abstract Timely administration of denosumab every 6 mo is critical in osteoporosis treatment to avoid multiple vertebral fracture risk upon denosumab discontinuation or delay. This study aimed to estimate the immediate and prolonged impact of the COVID-19 pandemic on the timing of denosumab doses. We identified older adults (≥66 yr) residing in the community who were due to receive denosumab between January 2016 and December 2020 using Ontario Drug Benefit data. We completed an interrupted time-series analysis to estimate the impact of the COVID-19 pandemic (March 2020) on the monthly proportion of on-time denosumab doses (183 +/−30 d). Analyses were stratified by user type: patients due for their second dose (novice users), third or fourth dose (intermediate users), or ≥5th dose (established users). In additional analyses, we considered patients living in nursing homes, switching to other osteoporosis drugs, and reported trends until February 2022. We studied 148 554 patients (90.9% female, mean [SD] age 79.6 [8.0] yr) receiving 648 221 denosumab doses. The average pre-pandemic proportion of on-time therapy was steady in the community, yet differed by user type: 64.9% novice users, 72.3% intermediate users, and 78.0% established users. We identified an immediate overall decline in the proportion of on-time doses across all user types at the start of the pandemic: −17.8% (95% CI, −19.6, −16.0). In nursing homes, the pre-pandemic proportion of on-time therapy was similar across user types (average 83.5%), with a small decline at the start of the pandemic: −3.2% (95% CI, −5.0, −1.2). On-time therapy returned to pre-pandemic levels by October 2020 and was not impacted by therapy switching. Although on-time dosing remains stable as of February 2022, approximately one-fourth of patients in the community do not receive denosumab on-time. In conclusion, although pandemic disruptions to denosumab dosing were temporary, levels of on-time therapy remain suboptimal.

Introduction The aim of our study was to assess the initial impact of COVID-19 on total publicly-funded direct healthcare costs and health services use in two Canadian provinces, Ontario and British Columbia (BC). Methods This retrospective repeated cross-sectional study used population-based administrative datasets, linked within each province, from January 1, 2018 to December 27, 2020. Interrupted time series analysis was used to estimate changes in the level and trends of weekly resource use and costs, with March 16–22, 2020 as the first pandemic week. Also, in each week of 2020, we identified cases with their first positive SARS-CoV-2 test and estimated their healthcare costs until death or December 27, 2020. Results The resources with the largest level declines (95% confidence interval) in use in the first pandemic week compared to the previous week were physician services [Ontario: -43% (-49%,-37%); BC: -24% (-30%,-19%) (both p<0.001)] and emergency department visits [Ontario: -41% (-47%,-35%); BC: -29% (-35%,-23%) (both p<0.001)]. Hospital admissions declined by 27% (-32%,-23%) in Ontario and 21% (-26%,-16%) in BC (both p<0.001). Resource use subsequently rose but did not return to pre-pandemic levels. Only home care and dialysis clinic visits did not significantly decrease compared to pre-pandemic. Costs for COVID-19 cases represented 1.3% and 0.7% of total direct healthcare costs in 2020 in Ontario and BC, respectively. Conclusions Reduced utilization of healthcare services in the overall population outweighed utilization by COVID-19 patients in 2020. Meeting the needs of all patients across all services is essential to maintain resilient healthcare systems.

AbstractHospital admissions due to acute cardiovascular events dropped during the COVID-19 pandemic in the general population; however, evidence for residents of long-term care facilities (LTCF) is sparse. We investigated rates of hospital admissions and deaths due to myocardial infarction (MI) and stroke in LTCF residents during the pandemic. Our nationwide cohort study used claims data. The sample comprised 1,140,139 AOK-ensured LTCF residents over 60 years of age (68.6% women; age 85.3 ± 8.5 years) from the largest statutory health insurance in Germany (AOK), which is not representative for all LTCF residents. We included MI and stroke admission and compared numbers of in-hospital deaths from January 2020 to end of April 2021 (i.e., during the first three waves of the pandemic) with the number of incidences in 2015–2019. To estimate incidence risk ratios (IRR), adjusted Poisson regression analyses were applied. During the observation period (2015–2021), there were 19,196 MI and 73,953 stroke admissions. MI admissions declined in the pandemic phase by 22.5% (IRR = 0.68 [CI 0.65–0.72]) compared to previous years. This decline was slightly more pronounced for NSTEMI than for STEMI. MI fatality risks remained comparable across years (IRR = 0.97 [CI95% 0.92–1.02]). Stroke admissions dropped by 15.1% (IRR = 0.75 [CI95% 0.72–0.78]) in the pandemic. There was an elevated case fatality risk for haemorrhagic stroke (IRR = 1.09 [CI95% 1.03–1.15]) but not for other stroke subtypes compared to previous years. This study provides first evidence of declines in MI and stroke admissions and in-hospital deaths among LTCF residents during the pandemic. The figures are alarming given the acute nature of the conditions and the vulnerability of the residents.

ObjectivesPopulation-based chronic disease surveillance systems were likely disrupted by the COVID-19 pandemic. The objective of this study was to examine the immediate and ongoing impact of the COVID-19 pandemic on the claims-based incidence of dementia.MethodsWe conducted a population-based time series analysis from January 2015 to December 2021 in Ontario, Canada. We calculated the monthly claims-based incidence of dementia using a validated case ascertainment algorithm drawing from routinely collected health administrative data. We used autoregressive linear models to compare the claims-based incidence of dementia during the COVID-19 period (2020–2021) to the expected incidence had the pandemic not occurred, controlling for seasonality and secular trends. We examined incidence by source of ascertainment and across strata of sex, age, community size and number of health conditions.ResultsThe monthly claims-based incidence of dementia dropped from a 2019 average of 11.9 per 10 000 to 8.5 per 10 000 in April 2020 (32.6% lower than expected). The incidence returned to expected levels by late 2020. Across the COVID-19 period there were a cumulative 2990 (95% CI 2109 to 3704) fewer cases of dementia observed than expected, equivalent to 1.05 months of new cases. Despite the overall recovery, ascertainment rates continued to be lower than expected among individuals aged 65–74 years and in large urban areas. Ascertainment rates were higher than expected in hospital and among individuals with 11 or more health conditions.ConclusionsThe claims-based incidence of dementia recovered to expected levels by late 2020, suggesting minimal long-term changes to population-based dementia surveillance. Continued monitoring of claims-based incidence is necessary to determine whether the lower than expected incidence among individuals aged 65–74 and in large urban areas, and higher than expected incidence among individuals with 11 or more health conditions, is transitory.

Abstract Background: Despite the importance of virtual primary care, the evidence informing optimal and sustainable provision of virtual care (VC) for people living with dementia (PLWD) and their care partners is scarce. We aimed to describe VC provided by family physicians (FPs) for PLWD in Canada. Methods: Concurrent mixed-methods design. We analyzed questions related to VC in three nationwide cross-sectional surveys conducted with PLWD, care partners, and FPs in the first year of the COVID-19 pandemic. Virtual care was defined as two-way synchronous communication by telephone and/or a web camera. The prevalence of VC use among FPs, PLWD, and care partners was described, and logistic regression models were used to determine factors (sociodemographic, urbanicity, frequency of and availability of support for connecting to FPs, and FPs’ practice characteristics) associated with VC use. Inductive thematic analysis was performed on responses to open-ended questions to explore FPs’ perceptions of barriers and facilitators to using VC. Results: 131 PLWD, 341 care partners, and 125 FPs participated. 61.2% of PLWD, 59.5% of care partners, and 77.4% of FPs had used VC. The models for PLWD (included age and ethnicity) and care partners (included gender, urbanicity, and receiving support from a family member/friend to connect with FP) were inconclusive. Among FPs, having more than 20 years of practice was significantly associated with a decreased likelihood of providing VC (OR=0.23, 95%CI: 0.08-0.62, p<0.01). Care preferences (decision stage), office/family support (preparation stage), technology and family presence (execution stage), and remuneration for FPs (compensation stage) were the most commonly recurring themes affecting VC use. Conclusions: Virtual primary dementia care uptake was substantial and mainly performed via telephone. From the perspective of FPs, optimal VC provision requires patient-care partner-physician shared decision-making, interoperability in healthcare, support for performing VC, and appropriate compensation. Virtual care facilitates access to primary care and minimizes potential disruptions to in-person care for PLWD; however, its outcomes need further investigation.

Objectives To examine how the COVID-19 pandemic affected the demographic and clinical characteristics, in-hospital care, and outcomes of long-term care residents admitted to general medicine wards for non-COVID-19 reasons. Methods We conducted a retrospective cohort study of long-term care residents admitted to general medicine wards, for reasons other than COVID-19, in four hospitals in Toronto, Ontario between January 1, 2018 and December 31, 2020. We used an autoregressive linear model to estimate the change in monthly admission volumes during the pandemic period (March-December 2020) compared to the previous two years, adjusting for any secular trend. We summarized and compared differences in the demographics, comorbidities, interventions, diagnoses, imaging, psychoactive medications, and outcomes of residents before and during the pandemic. Results Our study included 2,654 long-term care residents who were hospitalized for non-COVID-19 reasons between January 2018 and December 2020. The crude rate of hospitalizations was 79.3 per month between March-December of 2018–2019 and 56.5 per month between March-December of 2020. The was an adjusted absolute difference of 27.0 (95% CI: 10.0, 43.9) fewer hospital admissions during the pandemic period, corresponding to a relative drop of 34%. Residents admitted during the pandemic period had similar demographics and clinical characteristics but were more likely to be admitted for delirium (pandemic: 7% pre-pandemic: 5%, p = 0.01) and were less likely to be admitted for pneumonia (pandemic: 3% pre-pandemic: 6%, p = 0.004). Residents admitted during the pandemic were more likely to be prescribed antipsychotics (pandemic: 37%, pre-pandemic: 29%, p <0.001) and more likely to die in-hospital (pandemic:14% pre-pandemic: 10%, p = 0.04) Conclusions and implications Better integration between long-term care and hospitals systems, including programs to deliver urgent medical care services within long-term care homes, is needed to ensure that long-term care residents maintain equitable access to acute care during current and future public health emergencies.

Background: Community-dwelling people with dementia have been affected by COVID-19 pandemic health risks and control measures that resulted in worsened access to health care and service cancellation. One critical access point in health systems is the emergency department. We aimed to determine the change in weekly rates of visits to the emergency department of community-dwelling people with dementia in Ontario during the first 2 waves of the COVID-19 pandemic compared with historical patterns. Methods: We conducted a population-based repeated cross-sectional study and used health administrative databases to compare rates of visits to the emergency department among community-dwelling people with dementia who were aged 40 years and older in Ontario during the first 2 waves of the COVID-19 pandemic (March 2020–February 2021) with the rates of a historical period (March 2019–February 2020). Weekly rates of visits to the emergency department were evaluated overall, by urgency and by chapter from the International Statistical Classification of Diseases and Related Health Problems, 10th Revision. We used Poisson models to compare pandemic and historical rates at the week of the lowest rate during the pandemic period and the latest week. Results: We observed large immediate declines in rates of visits to the emergency department during the COVID-19 pandemic (rate ratio [RR] 0.50, 95% confidence interval [CI] 0.47–0.53), which remained below historical levels by the end of the second wave (RR 0.88, 95% CI 0.83–0.92). Rates of both nonurgent (RR 0.33, 95% CI 0.28–0.39) and urgent (RR 0.51, 95% CI 0.48–0.55) visits to the emergency department also declined and remained low (RR 0.68, 95% CI 0.59–0.79, RR 0.91, 95% CI 0.86–0.96), respectively. Visits for injuries, and circulatory, respiratory and musculoskeletal diseases declined and remained below historical levels. Interpretation: Prolonged reductions in visits to the emergency department among people with dementia during the first 2 pandemic waves raise concerns about patients who delay seeking acute care services. Understanding the long-term effects of these reductions requires further research.
