Abstract Background Multiple conditions are more prevalent in some minoritised ethnic groups and are associated with higher mortality rate but studies examining differential mortality once conditions are established is US-based. Our study tested whether the association between multiple conditions and mortality varies across ethnic groups in England. Methods and Findings A random sample of primary care patients from Clinical Practice Research Datalink (CPRD) was followed from 1 st January 2015 until 31 st December 2019. Ethnicity, usually self-ascribed, was obtained from primary care records if present or from hospital records. Cox regression models were used to estimate mortality by number of long-term conditions, ethnicity and their interaction, with adjustment for age and sex for 532,059 patients with complete data. During five years of follow-up, 5.9% of patients died. Each additional long-term condition at baseline was associated with increased mortality. This association differed across ethnic groups. Compared with 50-year-olds of white ethnicity with no conditions, the mortality rate was higher for white 50-year-olds with two conditions (HR 1.77) or four conditions (HR 3.13). Corresponding figures were higher for 50-year-olds of Black Caribbean ethnicity with two conditions (HR=2.22) or four conditions (HR 4.54). The direction of the interaction of number of conditions with ethnicity showed higher mortality associated with long-term conditions in nine out of ten minoritised ethnic groups, attaining statistical significance in four (Pakistani, Black African, Black Caribbean and Black other ethnic groups). Conclusions The raised mortality rate associated with having multiple conditions is greater in minoritised ethnic groups compared with white people. Research is now needed to identify factors that contribute to these inequalities. Within the health care setting, there may be opportunities to target clinical and self-management support for people with multiple conditions from minoritised ethnic groups.
Abstract To compare the timeliness of nongovernmental and governmental communications of infectious disease outbreaks and evaluate trends for each over time, we investigated the time elapsed from the beginning of an outbreak to public reporting of the event. We found that governmental sources improved the timeliness of public reporting of infectious disease outbreaks during the study period.
Abstract Background Due to increases in the prevalence of dementia across Canada, the economic burden of dementia on provincial health systems is expected to rise. A better understanding of the phase‐specific costs of dementia care, such as periods immediately prior to and following diagnosis as well as other critical points in the life course are needed to support capacity planning. We estimated the phase‐specific costs of dementia over time among older adults and by sex. Method We identified a cohort of 164,640 Ontario residents aged 66+ years, ascertained with incident dementia and residing in the community between April 1 st , 2010 and March 31 st , 2017. Controls, who had no previous dementia diagnosis, were 1:1 propensity‐score matched to persons with dementia and individuals were followed to death or study end (March 31 st , 2018). Costs included inpatient care, emergency department care, ambulatory care, home care, long‐term care, physician and healthcare professional services, and prescription drugs. Phase‐based costing methodology examined mean net costs of dementia care throughout four phases of disease progression (pre‐diagnosis, initial, continuing, terminal) and 5‐year net costs. Result Persons with dementia and matched controls (mean age 81.3 years; 58.7% female) were followed for an average of 3.2 years. Mean net costs of dementia were highest in the terminal phase ($32,679), followed by the initial ($17,656) and continuing phases ($13,423). Higher costs in the dementia group in the terminal phase were driven by acute care (net cost: $16,324, 95% CI [15,478, 17,170]) and long‐term care ($14,006, 95% CI [13,848, 14,164]). Net home care costs were highest in the initial phase ($1,839, 95% CI [1,796, 1,882]). The net 5‐year cost of dementia was $48,077 (95% CI [$47,183, $48,970]; women had higher 5‐year net costs than men ($50,158, 95% CI [$49,053, $51,263] vs. $44,800, 95% CI [$43,323, $46,277]). Conclusion Observed higher net costs of dementia in specific phases (terminal) and sectors (acute care, long‐term care, home care) highlight where to target interventions to optimize healthcare use and costs that respects quality of life for older adults with dementia and their family care providers.
Objective/ApproachThe Black Health Equity Working Group's Applied Health Research Question aimed to compare cancer screening rates and surgical wait times between community health centre (CHC) clients based on race-related data and non-CHC clients. CHC client data was categorized by self-identified racial groups, with Black self-identification compared to non-Black racialized, White, and missing racial self-identification, and non-CHC clients. Health card numbers were encrypted to link individuals to the Primary Care Population dataset for breast, cervical, and colorectal cancer screening rates. Surgical wait time indicators, such as the number of patients undergoing surgery and average wait times for initial consultation and completed surgeries, were derived from the Wait Time Information System. Assessments were conducted semi-annually from fiscal year 2018 to 2021. ResultsFollowing the onset of COVID-19, CHC clients self-identifying as Black experienced the most significant decrease (6.8%) in colorectal screenings compared to other groups. Mammogram screenings remained consistently higher for CHC clients self-identifying as Black pre- and post-pandemic. Average cervical cancer screening rates were approximately 8% higher among CHC clients compared to non-CHC clients, irrespective of racial self-identification. However, due to small sample sizes and missing data among self-identified racial groups, trends in surgical wait times for both CHC and non-CHC clients were unstable. Conclusion/ImplicationsTailored interventions targeting Black CHC clients can enhance cancer screening rates, particularly colorectal screenings. The analysis of CHC data offers valuable insights into race-based disparities in health outcomes. Improved data completeness is essential for accurately assessing health outcome variations among different racial groups.
Practitioners and researchers in health services and public health routinely estimate population health indicators from a range of data sources. These indicators are used in many settings to describe health status, monitor quality of care, and evaluate the effect of interventions. The data and knowledge necessary to calculate indicators, however, are scattered across different health settings, resulting in inconsistent and fragmented indicators and an inefficient use of population health information in research and practice. The Population Health Record (PopHR) described in this paper is an informatics platform for semi-automated integration of disparate data to enable measurement and monitoring of population health status and determinants. The research and development to build the PopHR uses AI methods to perform many tasks, including calculation of indicators and interaction with users.
IntroductionCurrent cost estimates for dementia in Canada are lacking and no studies have yet to examine the incremental healthcare costs associated with both dementia and frailty, despite evidence of increasing prevalence of both conditions and their bidirectional association. These data are essential for informed clinical and public policy programs.
Objectives and ApproachUsing linked clinical and health administrative databases in Ontario, we conducted a cohort study of all long-stay home care clients aged 50+ years with a clinical assessment between April 2014 and March 2015 (n=160,209). We defined dementia using a validated algorithm, and frailty categories (robust, pre-frail, frail) using a modified frailty index from clinical assessment data. Clients were followed prospectively for 1-year, for which we obtained total- and sector-specific healthcare costs for all encounters. We calculated cost differences (in $2015CAD) between dementia-frailty groups using a survival- and covariate-adjusted cost estimator described by Manning and Basu (2010) that included dementia-frailty interactions.
ResultsIn this population-based cohort of long-stay home care recipients, the prevalence of dementia was 26.8% and 33.3% of these clients were frail (vs. 26.9% among clients without dementia). Approximately 15% of the cohort died over the 1-year follow-up. The average 1-year estimated total health system cost was $26,965. On average, home care clients with dementia categorized as frail incurred $14,291 (SE=$139) more in charges than similar robust clients ($35,381 vs. $21,091, respectively). In contrast, frail persons without dementia incurred $12,796 (SE=$95) more in charges that similar robust clients ($33,659 vs. $20,864, respectively). Among frail persons, those with dementia incurred $1,722 (SE=$149) more in expenditures, on average. Wide variation in sector-specific costs were also observed by dementia and frailty strata.
Conclusion/ImplicationsDementia and frailty pose significant challenges to healthcare systems. Our findings illustrate large incremental costs associated with frailty, regardless of dementia status. Further research using the linked clinical assessment and administrative data is needed to inform variations in, and to delineate key drivers of, formal healthcare and informal care costs associated with dementia and frailty.
Abstract Research suggests that older adults with neurodegenerative diseases are at increased risk of developing a subsequent neurodegenerative or comorbid psychiatric disorder or both. Depression and other psychiatric conditions, though prevalent, are often under-diagnosed and under-treated among those with neurodegenerative conditions potentially leading to more rapid disease progression, poorer health outcomes and increased health care use. Few population-based studies have comprehensively examined the risk and temporal ordering of common neurodegenerative and psychiatric conditions, including whether these associations differ by age or sex. Initial findings regarding the incidence of ordered pairs of neurological conditions (including dementia, Parkinson’s disease and stroke) and psychiatric disorders (including mood and anxiety disorders, and schizophrenia) will be summarized. This population-based retrospective cohort study will provide essential data to allow policymakers, planners and providers to better anticipate the prognosis and care needs of older adults with comorbid neurodegenerative and psychiatric conditions.
Background: Providing equitable care to patients in need across the life course is a priority for many healthcare systems. Aim: To estimate socioeconomic inequality trends in the proportions of decedents that died in the community and that received palliative care within 30 days of death (including home visits and specialist/generalist physician encounters). Design: Cohort study based on health administrative data. Socioeconomic position was measured by area-level material deprivation. Inequality gaps were quantified annually and longitudinally using the slope index of inequality (absolute gap) and relative index of inequality (relative gap). Setting/Participants: A total of 729,290 decedents aged ⩾18 years in Ontario, Canada from 2009 to 2016. Results: In 2016, the modelled absolute gap (corresponding 95% confidence interval) between the most- and least-deprived neighbourhoods in community deaths was 4.0% (2.9–5.1%), which was 8.6% (6.2–10.9%) of the overall mean (46.6%). Relative to 2009, these inequalities declined modestly. Inequalities in 2016 were evident for palliative home visits (6.8% (5.8–7.8%) absolute gap, 26.3% (22.5–30.0%) relative gap) and for physician encounters (6.8% (5.7–7.9%) absolute gap, 13.2% (11.0–15.3%) relative gap), and widened from 2009 for physician encounters only on the absolute scale. Inequalities varied considerably across disease trajectories (organ failure, terminal illness, frailty, and sudden death). Conclusion: Key measures of end-of-life care are not achieved equally across socioeconomic groups. These data can be used to inform policy strategies to improve delivery of palliative and end-of-life services.
