Risk Factors Associated With COVID-19 Outcomes Among People With Intellectual and Developmental Disabilities Receiving Residential Services

Covid-19 patterns among adults with intellectual and developmental disability and the general population in New York state during the first year of the pandemic

BACKGROUND

People with intellectual and developmental disabilities (IDD) in the US, especially those living in group homes, experienced comparatively higher Covid-19 case/case fatality rates than the general population during the first year of the pandemic. There is no information about the patterns of case/case fatality rates during this time.

OBJECTIVE

This study compared Covid-19 case/case fatality rates among people with IDD living in residential group homes to the general population across the first year of the pandemic in New York State (NYS).

METHODS

Covid-19 positive cases and deaths collected from New York Disability Advocates (NYDA), a coalition of organizations serving individuals with IDD, was compared to data for the NYS general population from the first pandemic year. Case rates/100,000 and case fatality rates were calculated for the study period. Joinpoint Trend Analysis Software was used to analyze patterns in weekly case/case fatality rates.

RESULTS

Case fatality rates for people with IDD were higher than for the overall state population throughout the pandemic's first year. Case rates were higher among people with IDD across most of this year. Although the patterns in rates were similar, there was a sharp increase in cases for those with IDD during Fall 2020 beginning eight weeks before the general NYS population and a significant decrease in fatalities in late December 2020 into January 2021.

CONCLUSIONS

Consistently higher case fatality rates and significant differences in case/case fatality rates for people with IDD living in group homes require further consideration. Planning for future emergencies will require an enhanced federal/state understanding of the needs of people with IDD and a responsive surveillance system.

Understanding COVID-19 infection among people with intellectual and developmental disabilities using machine learning

BACKGROUND

People with intellectual and developmental disabilities (IDD) were disproportionately affected by the COVID-19 pandemic. Predicting COVID-19 infection has been difficult.

OBJECTIVE

We sought to address two research questions in this study: 1) to assess the overall utility of a machine learning model to predict COVID-19 diagnosis for people with IDD, and 2) to determine the primary predictors of COVID-19 diagnosis in a random sample of Home and Community Based Services users in one state.

METHODS

We merged three major IDD-specific datasets (National Core Indicators, Supports Intensity Scale, Medicaid HCBS expenditures) from one state to create one combined dataset for analyses that included more than 700 variables. We then built a random forest machine learning algorithm to predict COVID-19 diagnosis and to explore the top predictors of such a diagnosis, when present.

RESULTS

Our algorithm predicted COVID-19 diagnosis in a random sample of HCBS users with IDD with 62.5% accuracy. The top predictors of having a documented case of COVID-19 among our sample were higher age, having high overall, medical, or behavioral support needs, living in a lower-income neighborhood, total Medicaid expenditure, and higher body mass index.

CONCLUSIONS

Results largely followed trends in the general population, and were largely suggestive that increased contact with other people may have exposed a person with IDD to greater COVID-19 risk.

Using simulation modeling to inform intervention and implementation selection in a rapid stakeholder-engaged hybrid effectiveness-implementation randomized trial

BACKGROUND

Implementation research generally assumes established evidence-based practices and prior piloting of implementation strategies, which may not be feasible during a public health emergency. We describe the use of a simulation model of the effectiveness of COVID-19 mitigation strategies to inform a stakeholder-engaged process of rapidly designing a tailored intervention and implementation strategy for individuals with serious mental illness (SMI) and intellectual/developmental disabilities (ID/DD) in group homes in a hybrid effectiveness-implementation randomized trial.

METHODS

We used a validated dynamic microsimulation model of COVID-19 transmission and disease in late 2020/early 2021 to determine the most effective strategies to mitigate infections among Massachusetts group home staff and residents. Model inputs were informed by data from stakeholders, public records, and published literature. We assessed different prevention strategies, iterated over time with input from multidisciplinary stakeholders and pandemic evolution, including varying symptom screening, testing frequency, isolation, contact-time, use of personal protective equipment, and vaccination. Model outcomes included new infections in group home residents, new infections in group home staff, and resident hospital days. Sensitivity analyses were performed to account for parameter uncertainty. Results of the simulations informed a stakeholder-engaged process to select components of a tailored best practice intervention and implementation strategy.

RESULTS

The largest projected decrease in infections was with initial vaccination, with minimal benefit for additional routine testing. The initial level of actual vaccination in the group homes was estimated to reduce resident infections by 72.4% and staff infections by 55.9% over the 90-day time horizon. Increasing resident and staff vaccination uptake to a target goal of 90% further decreased resident infections by 45.2% and staff infections by 51.3%. Subsequent simulated removal of masking led to a 6.5% increase in infections among residents and 3.2% among staff. The simulation model results were presented to multidisciplinary stakeholders and policymakers to inform the "Tailored Best Practice" package for the hybrid effectiveness-implementation trial.

CONCLUSIONS

Vaccination and decreasing vaccine hesitancy among staff were predicted to have the greatest impact in mitigating COVID-19 risk in vulnerable populations of group home residents and staff. Simulation modeling was effective in rapidly informing the selection of the prevention and implementation strategy in a hybrid effectiveness-implementation trial. Future implementation may benefit from this approach when rapid deployment is necessary in the absence of data on tailored interventions.

Hospitalisation and mortality among privately insured individuals with COVID-19 in the United States: The role of intellectual disabilities and Neurogenetic disorders

BACKGROUND

Individuals with intellectual disabilities (IDs) and neurogenetic conditions (IDNDs) are at greater risk for comorbidities that may increase adverse outcomes for this population when they have coronavirus disease 2019 (COVID-19). The study aims are to examine the population-level odds of hospitalisation and mortality of privately insured individuals with COVID-19 with and without IDNDs IDs, controlling for sociodemographics and comorbid health conditions.

METHODS

This is a retrospective, cross-sectional study of 1174 individuals with IDs and neurogenetic conditions within a population of 752 237 de-identified, privately insured, US patients diagnosed with COVID-19 between February 2020 and September 2020. Odds of hospitalisation and mortality among COVID-19 patients with IDNDs adjusted for demographic characteristics, Health Resources and Services Administration region, states with Affordable Care Act and number of comorbid health conditions were analysed.

RESULTS

Patients with IDNDs overall had higher rates of COVID-19 hospitalisation than those without IDNDs (35.01% vs. 12.65%, P < .0001) and had higher rates of COVID-19 mortality than those without IDNDs (4.94% vs. .88%, P < .0001). Adjusting for sociodemographic factors only, the odds of being hospitalised for COVID-19 associated with IDNDs was 4.05 [95% confidence interval (CI) 3.56-4.61]. Adjusting for sociodemographic factors and comorbidity count, the odds of hospitalisation for COVID-19 associated with IDNDs was 1.42 (95% CI 1.25-1.61). The odds of mortality from COVID-19 for individuals with IDNDs adjusted for sociodemographic factors only was 4.65 (95% CI 3.47-6.24). The odds of mortality from COVID-19 for patients with IDNDs adjusted for sociodemographic factors and comorbidity count was 2.70 (95% CI 2.03-3.60). A major finding of the study was that even when considering the different demographic structure and generally higher disease burden of patients with IDNDs, having a IDND was an independent risk factor for increased hospitalisation and mortality compared with patients without IDNDs.

CONCLUSIONS

Individuals with IDNDs had significantly higher odds of hospitalisation and mortality after adjusting for sociodemographics. Results remained significant with a slight attenuation after adjusting for sociodemographics and comorbidities. Adjustments for comorbidity count demonstrated a dose-response increase in odds of both hospitalisation and mortality, illustrating the cumulative effect of health concerns on COVID-19 outcomes. Together, findings highlight that individuals with IDNDs experience vulnerability for negative COVID-19 health outcomes with implications for access to comprehensive healthcare.

Vulnerabilities, care, and exposure to illness risks among people with intellectual disabilities in Brazil during the COVID-19 pandemic (2020-2021)

People with intellectual disabilities, especially those who require care, are among the most affected by severe forms of COVID-19 and COVID-19- related deaths. In this study we investigated how care needs and other vulnerabilities influence the possibility COVID-19 infection among people with intellectual disabilities in Brazil. Method: Descriptive quantitative study using an online questionnaire answered by 2,800 respondents with intellectual disabilities over the age of sixteen. Results: Individuals with a greater need for care had higher frequencies of positive COVID-19 diagnoses (6.5%-8%) and were approximately six times more likely to be infected by family members than those who did not have COVID-19 in the family. Conclusions: There is a need for specific government measures to protect people with intellectual disabilities and their caregivers, because those with greater care needs are the most exposed to risks of contagion and sickness and have potential vectors of infection among family members and caregivers.

Nursing Home Residents' COVID-19 Infections in the United States: A Systematic Review of Personal and Contextual Factors

Background: This mixed methods systemic review synthesizes the evidence about nursing home risks for COVID-19 infections. Methods: Four electronic databases (PubMed, Web of Science, Scopus, and Sage Journals Online) were searched between January 2020 and October 2022. Inclusion criteria were studies reported on nursing home COVID-19 infection risks by geography, demography, type of nursing home, staffing and resident's health, and COVID-19 vaccination status. The Mixed Methods Appraisal Tool (MMAT) was used to assess the levels of evidence for quality, and a narrative synthesis for reporting the findings by theme. Results: Of 579 initial articles, 48 were included in the review. Findings suggest that highly populated counties and urban locations had a higher likelihood of COVID-19 infections. Larger nursing homes with a low percentage of fully vaccinated residents also had increased risks for COVID-19 infections than smaller nursing homes. Residents with advanced age, of racial minority, and those with chronic illnesses were at higher risk for COVID-19 infections. Discussion and implications: Findings suggest that along with known risk factors for COVID-19 infections, geographic and resident demographics are also important preventive care considerations. Access to COVID-19 vaccinations for vulnerable residents should be a priority.

Prevalence and severity of COVID-19 among children and adolescents with autism spectrum disorders in the Republic of Korea

LAY ABSTRACT

It is more difficult to prevent coronavirus disease 2019 in children and adolescents with autism spectrum disorder, as they have trouble communicating and adjusting to their new daily lives like wearing masks and social distancing. However, there have not been many studies that focused on coronavirus disease 2019 among children and adolescents with autism spectrum disorder. We included all Korean citizens under the age of 19 as our study subjects. Among them, we found out the prevalence, severity, and case fatality of coronavirus disease 2019 in children and adolescents with and without autism spectrum disorder. The prevalence of coronavirus disease 2019 among children and adolescents with autism spectrum disorder was lower than that of those without autism spectrum disorder. For severity, children and adolescents with autism spectrum disorder were more likely to enter severe stages of disease and had higher hospitalization rates than those without autism spectrum disorder. There were no deaths among children and adolescents with autism spectrum disorder, while a few died among children and adolescents without autism spectrum disorder. However, due to the small number of deaths, it was difficult to determine whether there was a link between autism spectrum disorder and coronavirus disease 2019 deaths. We found that the appropriate quarantine policies have played a great role in sustaining overall low prevalence and higher hospitalization rates among children and adolescents with autism spectrum disorder than those without autism spectrum disorder. Furthermore, because Korea has fewer schools and facilities (i.e. personal care, social training, and skilled nursing facility) for children and adolescents with autism spectrum disorder than other countries, those with autism spectrum disorder have fewer social contacts than even before the COVID-19 pandemic.

Enhancing understanding of SARS-CoV-2 infection among individuals with Down syndrome: An integrative review

BACKGROUND

Down syndrome (DS) is a non-rare genetic condition that affects approximately 1 in every 800 live births worldwide. Further, it is associated with comorbidities, anatomical alterations of the respiratory tract, and immunological dysfunctions that make individuals more susceptible to respiratory infections.

OBJECTIVE

To systematize the current scientific knowledge about the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection among individuals with DS.

DESIGN AND SETTING

This integrative review was conducted at the Universidade Federal de São Carlos, São Paulo, Brazil.

METHODS

This review was conducted in the following databases: the Virtual Health Library (Biblioteca Virtual em Saúde, BVS), PubMed, and Web of Science, using MeSH descriptors. The search included English or Portuguese studies published between January 1, 2020, and October 14, 2022.

RESULTS

A total of 55 articles from 24 countries were selected, comprising 21 case-control or cohort studies, 23 case reports or series, and 11 narrative reviews or opinion studies. The articles were grouped into five categories: previous comorbidities, coronavirus disease 2019 (COVID-19) clinical features and evolution, cytokine storm and interleukins, living in institutions as a risk factor, and behavioral actions as a protective factor against SARS-CoV-2 infection.

CONCLUSION

Individuals with DS are more susceptible to COVID-19 infection due to variables such as previous comorbidities, immunological factors, and their habitable environments. These aspects confer a higher risk of infection and an unfavorable clinical course. The precise pathways involved in the pathophysiology of COVID-19 in individuals with DS are not clear, thus requiring further studies.

All-cause and cause-specific mortality among people with and without intellectual disabilities during the COVID-19 pandemic in the Netherlands: a population-based cohort study

BACKGROUND

Although high rates of COVID-19-related deaths have been reported for people with intellectual disabilities during the first 2 years of the pandemic, it is unknown to what extent the pandemic has impacted existing mortality disparities for people with intellectual disabilities. In this study, we linked a Dutch population-based cohort that contained information about intellectual disability statuses with the national mortality registry to analyse both cause-specific and all-cause mortality in people with and without intellectual disabilities, and to make comparisons with pre-pandemic mortality patterns.

METHODS

This population-based cohort study used a pre-existing cohort that included the entire Dutch adult population (everyone aged ≥18 years) on Jan 1, 2015, and identified people with presumed intellectual disabilities through data linkage. For all individuals within the cohort who died up to and including Dec 31, 2021, mortality data were obtained from the Dutch mortality register. Therefore, for each individual in the cohort, information was available about demographics (sex and date of birth), indicators of intellectual disability, if any, based on chronic care and (social) services use, and in case of death, the date and underlying cause of death. We compared the first 2 years of the COVID-19 pandemic (2020 and 2021) with the pre-pandemic period (2015-19). The primary outcomes in this study were all-cause and cause-specific mortality. We calculated rates of death and generated hazard ratios (HRs) using Cox regression analysis.

FINDINGS

At the start of follow-up in 2015, 187 149 Dutch adults with indicators of intellectual disability were enrolled and 12·6 million adults from the general population were included. Mortality from COVID-19 was significantly higher in the population with intellectual disabilities than in the general population (HR 4·92, 95% CI 4·58-5·29), with a particularly large disparity at younger ages that declined with increasing age. The overall mortality disparity during the COVID-19 pandemic (HR 3·38, 95% CI 3·29-3·47) was wider than before the pandemic (3·23, 3·17-3·29). For five disease groups (neoplasms; mental, behavioural, and nervous system; circulatory system; external causes; and other natural causes) higher mortality rates were observed in the population with intellectual disabilities during the pandemic than before the pandemic, and the pre-pandemic to during the pandemic difference in mortality rates was greater in the population with intellectual disabilities than in the general population, although relative mortality risks for most other causes remained within similar ranges compared with pre-pandemic years.

INTERPRETATION

The impact of the COVID-19 pandemic on people with intellectual disabilities has been greater than reflected by COVID-19-related deaths alone. Not only was the mortality risk from COVID-19 higher in people with intellectual disabilities than in the general population, but overall mortality disparities were also further exacerbated during the first 2 years of the pandemic. For disability-inclusive future pandemic preparedness this excess mortality risk for people with intellectual disabilities should be addressed.

Risk for Severe COVID-19 Outcomes among Persons with Intellectual Disabilities, the Netherlands

The COVID-19 pandemic has disproportionately affected persons in long-term care, who often experience health disparities. To delineate the COVID-19 disease burden among persons with intellectual disabilities, we prospectively collected data from 36 care facilities for 3 pandemic waves during March 2020-May 2021. We included outcomes for 2,586 clients with PCR-confirmed SARS-CoV-2 infection, among whom 161 had severe illness and 99 died. During the first 2 pandemic waves, infection among persons with intellectual disabilities reflected patterns observed in the general population, but case-fatality rates for persons with intellectual disabilities were 3.5 times higher and were elevated among those >40 years of age. Severe outcomes were associated with older age, having Down syndrome, and having >1 concurrent condition. Our study highlights the disproportionate COVID-19 disease burden among persons with intellectual disabilities and the need for disability-inclusive research and policymaking to inform disease surveillance and public health policies for this population.

[The situation of people with intellectual and developmental disabilities in the COVID-19 pandemic-risk factors, problem areas, and measures]

Many people with intellectual and developmental disabilities (IDD) were much more affected by COVID-19 than the average population. The morbidity in this population group was significantly higher due to the form of their housing and care as well as disability-associated health factors (such as Down's syndrome). This led, among other things, to a higher incidence of inpatient settings, a higher mortality rate among hospitalized patients, and a higher case fatality rate among certain subgroups. Risk factors were co-diseases such as dysphagia, epilepsy, or mental disorders. In addition, there were health consequences from restrictive exposure prophylaxis measures at the beginning of the COVID-19 pandemic.This overview article describes the main developments in the care of people with IDD since the beginning of the pandemic. New mental problems or an increase in existing mental problems occurred more frequently in people with IDD who were cared for on an outpatient basis or by relatives. People with IDD in inpatient residential facilities were less frequently affected. The main reasons for psychological problems were lack of social contacts, lost work and employment opportunities, the frightening pandemic situation, and the major structural and personnel changes in the facilities at the beginning of the pandemic. During the pandemic, there were also problems with the implementation of therapeutic and preventive measures. On the other hand, especially in the inpatient area, the "slowing down of life" associated with the restrictions at the beginning of the pandemic also had a stress-reducing effect on some of the people with IDD and was perceived by them as something positive. Caregivers had more time for the genuine (i.e., pedagogical) work. Overall, it was shown that health-promoting measures must also take into account the great heterogeneity of the people with IDD and their living conditions during the pandemic.

COVID-19 mortality burden and comorbidity patterns among decedents with and without intellectual and developmental disability in the US

BACKGROUND

While there is ample evidence of increased COVID-19 mortality risk among people with intellectual and developmental disability (IDD), research has not documented whether this higher risk resulted in increased COVID-19 mortality burden in the US or whether comorbidity patterns among COVID-19 deaths are similar or distinct for people with IDD.

OBJECTIVE

To determine the differences in COVID-19 mortality burden between decedents with and without IDD during the first year of the pandemic.

METHODS

This study uses 2020 US death certificate data to compare COVID-19 mortality burden and comorbidity patterns among decedents with and without IDD.

RESULTS

COVID-19 was the leading cause of death among decedents with IDD in 2020, compared with the 3rd leading cause among decedents without IDD. The proportion of deaths from COVID-19 was also higher for decedents with compared to without IDD. Comorbidities resulting from COVID-19 were similar among decedents with and without IDD, but there were some differences among reported pre-existing conditions, notably higher rates of hypothyroidism and seizures among decedents with IDD.

CONCLUSION

The COVID-19 mortality burden was greater for people with than without IDD during the first year of the pandemic. The continued practice of postmortem diagnostic overshadowing prevents analyzing whether this difference continues through today. Action is needed by the Centers for Disease Control and Prevention to mitigate this data inequity. Out of an abundance of caution, medical providers should carefully monitor symptoms among COVID-19 patients with IDD diagnosed with hypothyroidism and/or seizures.

COVID-19 in French nursing homes during the second pandemic wave: a mixed-methods cross-sectional study

INTRODUCTION

French nursing homes were deeply affected by the first wave of the COVID-19 pandemic, with 38% of all residents infected and 5% dying. Yet, little was done to prepare these facilities for the second pandemic wave, and subsequent outbreak response strategies largely duplicated what had been done in the spring of 2020, regardless of the unique needs of the care home environment.

METHODS

A cross-sectional, mixed-methods study using a retrospective, quantitative data from residents of 14 nursing homes between November 2020 and mid-January 2021. Four facilities were purposively selected as qualitative study sites for additional in-person, in-depth interviews in January and February 2021.

RESULTS

The average attack rate in the 14 participating nursing facilities was 39% among staff and 61% among residents. One-fifth (20) of infected residents ultimately died from COVID-19 and its complications. Failure to thrive syndrome (FTTS) was diagnosed in 23% of COVID-19-positive residents. Those at highest risk of death were men (HR=1.78; 95% CI: 1.18 to 2.70; p=0.006), with FTTS (HR=4.04; 95% CI: 1.93 to 8.48; p<0.001) or in facilities with delayed implementation of universal FFP2 masking policies (HR=1.05; 95% CI: 1.02 to 1.07; p<0.001). The lowest mortality was found in residents of facilities with a partial (HR=0.30; 95% CI: 0.18 to 0.51; p<0.001) or full-time physician on staff (HR=0.20; 95% CI: 0.08 to 0.53; p=0.001). Significant themes emerging from qualitative analysis centred on (1) the structural, chronic neglect of nursing homes, (2) the negative effects of the top-down, bureaucratic nature of COVID-19 crisis response, and (3) the counterproductive effects of lockdowns on both residents and staff.

CONCLUSION

Despite high resident mortality during the first pandemic wave, French nursing homes were ill-prepared for the second, with risk factors (especially staffing, lack of medical support, isolation/quarantine policy, etc) that affected case fatality and residents' and caregivers' overall well-being and mental health.

Incidence, Hospitalization, Mortality and Risk Factors of COVID-19 in Long-Term Care Residential Homes for Patients with Chronic Mental Illness

Long-term care residential homes (LTCRH) for patients with chronic mental illness have suffered the enormous impact of COVID-19. This study aimed to estimate incidence, hospitalization, mortality, and risk factors of COVID-19 to prevent future epidemics. From March 2020 to January 2021 and before vaccination anti-SARS-CoV-2 begins, cumulate incidence rate (CIR), hospitalization rate (HR), mortality rate (MR), and risk factors of COVID-19 in the 11 LTCRH of two Health Departments of Castellon (Spain) were studied by epidemiological surveillance and an ecological design. Laboratory tests confirmed COVID-19 cases, and multilevel Poisson regression models were employed. All LTCRH participated and comprised 346 residents and 482 staff. Residents had a mean age of 47 years, 40% women, and suffered 75 cases of COVID-19 (CIR = 21.7%), five hospitalizations (HR = 1.4%), and two deaths (MR = 0.6%) with 2.5% fatality-case. Staff suffered 74 cases of the disease (CIR = 15.4%), one hospitalization (HR = 0.2%), and no deaths were reported. Risk factors associated with COVID-19 incidence in residents were private ownership, severe disability, residents be younger, CIR in municipalities where LTCRH was located, CIR in staff, and older age of the facilities. Conclusion: COVID-19 incidence could be prevented by improving infection control in residents and staff and modernizing facilities with increased public ownership.

COVID-19 Precautions Experienced by a Sample of Adults with Intellectual and Developmental Disabilities

Purpose

This study describes factors associated with COVID-19 precautions (i.e., self-isolation and the use of personal protective equipment) among a sample of adults with intellectual and developmental disabilities (IDD) in Ontario, Canada.

Methods

The sample included 756 home care recipients with IDD who did not test positive for COVID-19 between March 2020 and July 2021. Among these, some received COVID-19 precautions. Precaution data were obtained from a large metropolitan organization serving persons with IDD in Ontario, and linked to home care assessment data. Unadjusted and adjusted odds ratios with 95% confidence intervals were calculated using logistic regression models to examine the association between COVID-19 cautions and demographic and clinical factors. Effect modification and interactions were explored.

Results

One hundred twenty-seven (16.8%) home care clients experienced precautions. After adjustment, congregate setting, aggression, and limited mobility were significantly associated with COVID-19 precautions. Age modified the relationship between congregate setting and precautions.

Conclusions

Pandemic responses need to recognize the impact on subgroups of adults with IDD, such as those living in congregate settings (including younger individuals) or engaging in responsive behaviors. How these precautions impacted individuals–in the short and long term–warrants further investigation.

The COVID-19 vaccine intentions of Australian disability support workers

OBJECTIVES

Describe perceptions of COVID-19, COVID-19 vaccines, information sources, and levels and reasons for vaccine hesitancy among disability support workers (DSWs).

METHODS

Cross-sectional survey of 252 DSWs from across Australia, between early March and early April 2021. Perceptions of risk of COVID-19; government and media representations; vaccination status (Y/N); vaccine intentions (when offered, delayed vaccinators, vaccine refusers); reasons for hesitancy; confidence in safety and efficacy of vaccine; and information sources.

RESULTS

At the time of the survey, fewer than 1% of DSWs had been vaccinated and 17% had been offered vaccination. Of those who had not had the vaccine, 47% said they would get it as soon as it was offered; 19% would not get the vaccine; 12% would have if required; 13% hadn't decided; and 8% would wait until it was available for a while. Reasons for hesitancy included inadequate safety data (70% delayed vaccinators, 79% vaccine refusers), side effects (63% delayed vaccinators, 58% refusers), and distrust in the government (17% delayed vaccinators, 52% refusers). DSWs most trusted sources of information were their own doctor, Chief Medical Officers, and governments. 61% believed that COVID-19 will only stop if most of the community is vaccinated and 53% agreed the chances of them or their clients getting COVID-19 would be reduced if they were vaccinated.

CONCLUSIONS

Tailored information is needed to reduce vaccine hesitancy and increase confidence in COVID-19 vaccines among DSWs. The importance of getting vaccinated to prevent COVID-19 among people with disability should be emphasised.

Short Report: The influence of congregate setting on positive COVID-19 tests among a high-risk sample of adults with intellectual and developmental disability in Ontario

BACKGROUND

For a number of reasons, persons with intellectual and developmental disability (IDD) are at increased risk of contracting COVID-19.

AIMS

This study explored the influence of congregate setting on testing positive for COVID-19 among adults with IDD in Ontario.

METHODS AND PROCEDURES

833 home care recipients with IDD were included, 204 were tested at least once for COVID-19. These data were linked to the homecare assessment data. The association between living in a congregate setting and receiving a positive COVID-19 test was explored using a logistic regression model among the total sample and those tested for COVID-19.

OUTCOMES AND RESULTS

77 individuals tested positive for COVID-19 (9.24 %). Congregate setting, age, aggression, and mobility were significantly associated with receiving a positive COVID-19 test in the total sample. Among the subgroup, congregate setting and age were significant.

CONCLUSION AND IMPLICATIONS

Adults with IDD have an increased risk for positive COVID-19 tests at younger ages than other high-risk populations, such as elderly persons. These findings confirm the vulnerability of adults with IDD living in group settings to COVID-19. As such, they should be prioritized when COVID-19 prevention and public health strategies, including vaccination and boosters, are introduced.

Intellectual disability and COVID-19: A bibliometric review

BACKGROUND

During the COVID-19 pandemic, the vulnerabilities of certain groups of people have been highlighted, such as people with intellectual disability (ID). Although related research on ID has developed rapidly during the COVID-19 pandemic, the quantitative analysis of those research results has not been systematically performed through bibliometric analysis. Bibliometric analysis is a useful and rigorous method to explore large volumes of research data, and it allows researchers to extract quantitative information on distribution by author, time, country, and journal.

AIM

The aim of the present study is to comprehensively analyze the current status and developing trends in publications on ID research related to and conducted during the COVID-19 pandemic.

METHODS

A bibliometric analysis was performed using the Web of Science database. Biblioshiny software was used to analyze and visualize the following information: main information of dataset, annual scientific production, journals which published the most relevant sources, most-cited authors, most-cited countries, most-cited global documents, word-cloud of keywords authors have used, and both the co-occurrence and co-citation networks.

RESULTS

A total of 450 publications were included. The average number of citations per document was 5.104. Among the top three journals, Journal of Applied Research in Intellectual Disabilities published 32 articles, Journal of Intellectual Disability Research published 29 articles, and British Journal of Learning Disabilities published 17 articles. The article with the title COVID-19 and People with Intellectual Disability: Impact of a Pandemic was the most cited with total 144 citations The United Kingdom had the most publications and had strong cooperative relationships with the United States, Canada, and Australia. The most popular keywords included mental health, autism, developmental disability, and lockdown. Thematic map analysis identified several possible clusters, including telemedicine, physical activities, and mental health.

CONCLUSION

The present study provides a better understanding in this research field and may help clinicians, researchers and stakeholders to obtain more comprehensive view of ID and COVID-19. The insights gained from this analysis could inform future research.

COVID-19 positivity rates, hospitalizations and mortality of adults with and without intellectual and developmental disabilities in Ontario, Canada

Background

Across and within countries there is a need to understand how the COVID-19 pandemic has impacted populations of individuals with intellectual and developmental disabilities (IDD).

Objective

Rates of COVID-19 positivity for adults with IDD, including Down syndrome, relative to adults without IDD in Ontario, Canada were compared. Health profiles and case-based rates of hospitalizations, intensive care unit admissions, and mortality within 30 days of testing positively were compared for those with IDD, including Down syndrome, versus those without IDD.

Methods

This retrospective cohort study linked health administrative databases using unique encoded identifiers to describe population-level COVID-19 positivity, related hospital use and mortality from January 15, 2020 to January 10, 2021. Incidence rate ratios (RR) and 95% confidence intervals were calculated.

Results

Relative to adults without IDD, COVID-19 positivity rates were 1.28 times higher for adults with IDD and 1.42 times higher for adults with Down syndrome.

Compared to adults without IDD, adults with IDD were more than twice as likely to be hospitalized following COVID-19 (RR:2.21 (95%CI: 1.93,2.54)) and to die (RR:2.23 (95%CI: 1.86,2.67). These RRs were greater for adults under 65. For adults with Down syndrome, mortality rates were 6.59 (95%CI: 4.51,9.62) times higher than those without IDD.

Discussion

In Ontario, Canada, hospitalization and mortality rates associated with COVID-19 are higher for adults with IDD than other adults. These findings should inform vaccination strategies that often prioritize older adults in the general population resulting in people with IDD, who are often in younger age groups, being overlooked.
