Investigating inequalities in cancer staging and survival for adults with intellectual or developmental disabilities and cancer: A population-based study in Manitoba, Canada.

BACKGROUND: Cancer is a leading cause of death among adults living with intellectual or developmental disabilities (IDD). However, few epidemiological studies exist worldwide quantifying inequalities in cancer stage at diagnosis and survival for people with IDD relative to those without IDD. METHODS: A population-based, retrospective cohort study was conducted using provincial health and social administrative data in Manitoba, Canada. Adults (≥18 years) with a cancer diagnosis between 2004 and 2017 were included. Lifetime IDD was identified before the cancer diagnosis using an established algorithm. Modified Poisson regression with robust error variance was used to estimate the association between IDD status and metastatic cancer at diagnosis. Multivariable Cox proportional hazards analyses were used to the effect of IDD on overall survival following the cancer diagnosis. RESULTS: The staging and prognosis cohorts included 62,886 (n = 473 with IDD) and 74,143 (n = 592 with IDD) cancer patients, respectively. People living with IDD were significantly more likely to be diagnosed with metastatic cancer and die following their cancer diagnosis compared to those without IDD (RR=1.20; 95 % CI 1.05-1.38; HR= 1.53; 95 % CI 1.38-1.71). Significant heterogeneity by sex was identified for cancer survival (p = 0.005). DISCUSSION: People with IDD had more advanced cancer stage at diagnosis and worse survival relative to those without IDD. Identifying and developing strategies to address the factors responsible that contribute to these disparities is required for improving patient-centred cancer care for adults with IDD.

Organizational attributes of interprofessional primary care for adults with intellectual and developmental disabilities in ontario, Canada: a multiple case study.

BACKGROUND: Access to high-quality primary care has been identified as a pressing need for adults with intellectual and developmental disabilities (IDD). Adults with IDD live with complex physical and mental health conditions, use health services differently than the general population and continue to face challenges when accessing health services. Interprofessional primary care teams offer comprehensive and coordinated approaches to primary care delivery and are well-positioned to address the needs of adults with IDD and other vulnerable populations. Although interprofessional primary care teams are recommended, there is currently limited understanding of how interprofessional care is delivered and how access to a team of providers improves the health of this population. The aim of this paper is to describe the organizational attributes of interprofessional primary care for adults with IDD within and across models of team-based care in one local health service context. METHODS: A multiple case study was conducted with five interprofessional primary care teams in Ontario, Canada. Multiple methods were used to generate data including: a survey, document review, electronic medical record report and qualitative interviews. Pattern matching was the primary analytic approach for the within and across case analysis. RESULTS: Adults with IDD were found to be a small part of the patient population served and this group was poorly identified in three of five teams. Key organizational attributes that support the delivery of interprofessional primary care for adults with IDD were identified. Two examples of targeted programs of care for this group were also found. Despite the presence of interprofessional health providers in all teams, there were limited organizational processes to engage a wide-range of interprofessional services in the care of this group. There was no consistent reporting of outcomes or processes in place to measure the impact of interprofessional services for this population. CONCLUSIONS: This study provides important insights into the current state of interprofessional primary care for adults with IDD in Ontario and highlight a critical need for further work in the field to develop organizational structures and processes to engage in team-based care and demonstrate the value of the approach for this population.

Scoping review protocol documenting cancer outcomes and inequalities for adults living with intellectual and/or developmental disabilities.

INTRODUCTION: There is increasing attention on the cancer burden for adults with intellectual and developmental disabilities (IDD). Emerging evidence suggests there are differences in cancer experiences and outcomes for individuals living with IDD, from risk through survivorship. These differences may be attributed to features of the IDD, such as cognitive deficits and communication, as well as social determinants of health-like lower education levels and ableism. However, there is no comprehensive overview of the literature quantifying these potential disparities and describing the influencing factors. In this paper, we describe a scoping review protocol to systematically review published literature on cancer for adults with IDD. The purpose of this review is to identify differences in cancer risk, stage at diagnosis, treatment and survival along the cancer continuum for adults with IDD and outline potential contributing factors creating these disparities. METHODS AND ANALYSIS: We will follow Arksey and O'Malley's expanded framework for scoping reviews to conduct this review. We will systematically search electronic databases for peer-reviewed, published journal articles to identify appropriate studies in collaboration with a health science librarian. Two reviewers will independently review titles and abstracts followed by a full-text review to determine whether it meets inclusion criteria. A data chart for collecting and sorting information will be developed in consultation with the team. Results will be collated and reported following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) extension for scoping reviews: PRISMA-Scoping Reviews. Extracted information will be summarised quantitatively and qualitatively to meet review objectives. ETHICS AND DISSEMINATION: This scoping review will employ a methodology to identify literature related to cancer outcomes and experiences for adults with IDD. Results will be disseminated to relevant stakeholders who care for and support individuals with IDD at local, provincial and national levels and through publishing findings. By highlighting the disparities in the cancer system and gaps in the research, this scoping review can provide direction for future action.

What adults with intellectual and developmental disabilities say they need to access annual health examinations: System navigation support and person-centred care.

OBJECTIVE: To gain an understanding of the support needs of adults with intellectual and developmental disabilities (IDD) when scheduling, traveling to, and attending annual health examinations (AHEs). DESIGN: Qualitative study that is part of a large population-level intervention aiming to increase uptake of AHEs among adults with IDD. SETTING: Ontario. PARTICIPANTS: A total of 8 men and 5 women with IDD took part in semistructured interviews about their personal experiences related to AHEs. METHODS: Thematic analysis was used to examine experiences relating to scheduling, traveling to, and attending AHEs. MAIN FINDINGS: Support emerged as the overarching theme. Support included assistance navigating the health care system (assistance scheduling AHEs, reminders to book AHEs, financial assistance, transportation) and person-centred care (respect of privacy and autonomy, communication style, kindness, compassion, rapport with physician, health advocacy, and collaboration). Barriers to this support were also identified (lack of rapport, perception of unfriendliness, perception that the physician is too busy to tend to needs, and perception that the physician did not want to perform AHEs). CONCLUSION: For adults with IDD, system navigation support and person-centred care were central to accessing AHEs. In collaboration with informal caregivers, physicians have an important role in reducing barriers to patients accessing this valuable preventive care opportunity. Physicians can fulfil some of the needs disclosed by adults with IDD related to attending AHEs by offering support for scheduling appointments, by linking patients with IDD to resources that facilitate appointment attendance, and by increasing consultation duration.

Comprehensive preventive care assessments for adults with intellectual and developmental disabilities: Part 2: 2003 to 2014.

OBJECTIVE: To determine if there has been an increase in preventive care among adults with intellectual and developmental disabilities (IDD) as a result of the publication of the Canadian consensus guidelines on the care of adults with IDD in 2006 and 2011. DESIGN: Ecological study. SETTING: Ontario. PARTICIPANTS: The study group consisted of community-dwelling adults with IDD between the ages of 40 and 64 living in Ontario identified in 2009-2010 through administrative health and social services data. The comparison group consisted of a propensity-score-matched sample of the remaining Ontario population. MAIN OUTCOME MEASURES: A combined measure of a health examination or a Primary Care Quality Composite Score (PCQS) of 0.6 or greater, or both. Both measures were identified using administrative health data. RESULTS: Adults with IDD were 2.04% more likely to have had a health examination or a PCQS of 0.6 or greater before 2011-2012 and 1.70% less likely after 2011-2012. Adults without IDD were 1.03% more likely before 2011-2012 and 13.74% less likely after 2011-2012 to have had a health examination or a PCQS of 0.6 or greater. Male patients with IDD were 15.60% more likely and male patients without IDD were 7.39% less likely to have had a health examination or PCQS of 0.6 or greater compared with female patients. CONCLUSION: Despite the publication of the guidelines there has not been a corresponding increase in the uptake of the annual health examination or in the quality of preventive care among adults with IDD. More is required to reduce this documented inequity in care.

Market Segmentation as a Tool to Inform Health and Social Services Policy and Planning: The Case of Autism Spectrum Disorder and Intellectual Disability.

In the absence of complete public surveillance data, estimating the prevalence and needs of sub-groups of heterogeneous populations is nonetheless critical to properly inform health and social services planning and policy. We thus introduce market segmentation as an innovative tool for health and social services planners and policy makers. Segmentation is a process whereby broad populations are categorized into sub-groups with common characteristics and needs. Using the example of autism spectrum disorder and/or intellectual disability in Quebec, Canada, we triangulate available data and mathematical problem solving to present a portrait of the varying support needs of this under-served, yet growing, population.

Needles in the haystack: Using open-text fields to identify persons with intellectual and developmental disabilities in administrative home care data.

BACKGROUND: Use of administrative health data to study populations of interest is becoming more common. Identifying individuals with intellectual and developmental disabilities (IDD) in existing databases can be challenging due to inconsistent definitions and terminologies of IDD over time and across sectors, and the inability to rely on etiologies of IDD as they are frequently unknown. AIMS: To identify diagnoses related to IDD in an administrative database and create a cohort of persons with IDD. METHODS: Open-text diagnostic entries related to IDD were identified in an Ontario home care database (2003-2015) and coded as being either acceptable (e.g. Down syndrome) or ambiguous (e.g. intellectually challenged). The cognitive and functional skills of the resulting groups were compared using logistic regressions and standardized differences, and their age distributions were compared to that of the general home care population. RESULTS: Just under 1% of the home care population had a diagnostic entry related to IDD. Ambiguous terms were most commonly used (61%), and this group tended to be older and less impaired than the group with more acceptable terms used to describe their IDD. CONCLUSIONS: Open-text diagnostic variables in administrative health records can be used to identify and study individuals with IDD. IMPLICATIONS: Future work is needed to educate assessors on the importance of using standard, accepted terminology when recording diagnoses related to IDD.

Stakeholders' Perspectives towards the Use of the Comprehensive Health Assessment Program (CHAP) for Adults with Intellectual Disabilities in Manitoba.

BACKGROUND: No standardized tool is used in Canada for comprehensive health assessments of adults with intellectual disabilities. This study was conducted to determine the feasibility of implementing the Comprehensive Health Assessment Program (CHAP) in Manitoba, Canada. METHOD: This was a qualitative study using a purposive sample of physicians, nurse practitioners, support workers and families. Data were collected through individual interviews and focus groups and were analysed using content analysis. RESULTS: Use of the CHAP was perceived as beneficial for persons with intellectual disabilities. Improved continuity of care was of the reported benefits. Six barriers for the future implementation of the CHAP were identified including the time required to complete the CHAP, and the perceived lack of physicians' willingness to do comprehensive assessments. CONCLUSION: The future implementation of the CHAP was strongly supported. For its successful implementation, training of healthcare professionals and support staff and change in regulations and policies were recommended.

Informal Support and Burden among Parents of Adults with Intellectual and/or Developmental Disabilities.

BACKGROUND: Parents often play a lifelong role in supporting their sons and daughters with intellectual and/or developmental disabilities (IDD). There is a need to better understand parent resources, particularly when the individual with IDD has behaviour problems, as the latter has consistently been linked to parental burden. METHODS: The current study aimed to investigate the relationship between the behaviour support needs of 212 adults with IDD and parental burden, and whether perceived helpfulness of informal supports moderated this relationship. The helpfulness of individual sources of informal support was also explored. RESULTS: Informal support was negatively related to burden, although it did not act as a moderator. Individual sources varied in terms of how they were related to burden, but none acted as moderators. CONCLUSIONS: Although informal social support appears to be important to parents and may help alleviate burden, it does not appear to act as a moderator as anticipated.

Primary care of adults with developmental disabilities in Ontario.

The health status and healthcare of adults with developmental disabilities have not been well-studied in Ontario, due to the absence of population-based data. To address this deficit, the Health Care Access Research and Developmental Disabilities (H-CARDD) program - a provincial partnership of scientists, policymakers and clinicians - has used existing provincial-level administrative data to provide descriptive information on the health of adults with developmental disabilities and the quality of their primary care relative to other adults. H-CARDD's findings have revealed many gaps in the care of adults with developmental disabilities. While primary care providers are critical to achieving needed changes, the broader healthcare context and infrastructure also need to be considered.

Unmet needs of families of school-aged children with an autism spectrum disorder.

BACKGROUND: To aid decision making regarding the allocation of limited resources, information is needed on the perceived unmet needs of parents of school-aged children with an autism spectrum disorder. MATERIALS AND METHODS: A cross-sectional survey was conducted of 101 Canadian families of school-aged children with an autism spectrum disorder. RESULTS: Commonly reported unmet needs were for social activities for the child (78.2%), information about services (77.2%) and continuous service provision (74.3%). CONCLUSIONS: This study provides insight into needs which have not been met by the service system. Information about the unmet needs of children with an autism spectrum disorder and their families may help policy makers and service providers to develop resources and services that are responsive to their client group.

Beyond an autism diagnosis: children's functional independence and parents' unmet needs.

High demand has resulted in gaps in autism service provision. Our objective was to explore the association between children's functioning and parents' perceived unmet needs. We conducted a cross-sectional study of 97 families of school-aged children with an autism spectrum disorder. Log binomial regression was used to examine the relative risk for unmet need. Families of children with high functional independence had lower unmet need than families of children with moderate functional independence (RR = 0.81, 95% CI = 0.67-0.99). Those who experienced greater impact of the child's disability had greater unmet need (RR = 1.22, 95% CI = 1.03-1.45). The child's functioning and its impact on the family provide insight into unmet need which may inform service planning.

Organising health care services for persons with an intellectual disability.

BACKGROUND: When compared to the general population, persons with an intellectual disability have lower life expectancy, higher morbidity, higher rates of unmet health needs, and more difficulty finding and getting health care. Organisational interventions are used to reconfigure the structure or delivery of health care services and may prove useful to decrease the noted disparities. OBJECTIVES: To assess the effects of organisational interventions for the mental and physical health problems of persons with an intellectual disability. SEARCH STRATEGY: We searched the Cochrane Effective Practice and Organisation of Care Group specialised register (no year restriction), MEDLINE, EMBASE, CINAHL, other databases from January 1990 to April 2006 reference lists of included studies, and we consulted experts in the field. SELECTION CRITERIA: Randomised controlled trials, controlled clinical trials, controlled before and after studies and interrupted time series of organisational interventions aimed at improving care of mental and physical health problems of adult persons with an intellectual disability. DATA COLLECTION AND ANALYSIS: Two review authors independently extracted data and assessed study quality. Missing data were requested from authors of included studies. MAIN RESULTS: Eight studies met the selection criteria: six were randomised controlled trials, one was a controlled before and after study, and one was an interrupted time series. In general the studies were of acceptable methodological quality. The included studies investigated interventions dealing with the mental health problems of persons with an intellectual disability, none focused on physical health problems. Three of the studies identified effective organisational interventions and five showed no evidence of effect. Only two studies were similar enough to analyse using a meta-analysis. In the pooled analyses 25 participants received assertive community treatment and 25 received standard community treatment. Results from measures of function, caregiver burden and quality of life were non-significant. AUTHORS' CONCLUSIONS: There are currently no well designed studies focusing on organising the health services of persons with an intellectual disability and concurrent physical problems. There are very few studies of organisational interventions targeting mental health needs and the results of those that were found need corroboration. There is an urgent need for high quality health services research to identify optimal health services for persons with an intellectual disability and concurrent physical problem.

Addressing health disparities through promoting equity for individuals with intellectual disability.

Intellectual disabilities (ID) are conditions originating before the age of 18 that result in significant limitations in intellectual functioning and conceptual, social and practical adaptive skills. IDs affect 1 to 3% of the population. Persons with ID are more likely to have physical disabilities, mental health problems, hearing impairments, vision impairments and communication disorders. These co-existing disabilities, combined with the limitations in intellectual functioning and in adaptive behaviours, make this group of Canadians particularly vulnerable to health disparities. The purpose of this synthesis article is to explore potential contributory factors to health vulnerabilities faced by persons with ID, reveal the extent and nature of health disparities in this population, and examine initiatives to address such differences. The review indicates that persons with ID fare worse than the general population on a number of key health indicators. The factors leading to vulnerability are numerous and complex. They include the way society has viewed ID, the etiology of ID, health damaging behaviours, exposure to unhealthy environments, health-related mobility and inadequate access to essential health and other basic services. For persons with ID there are important disparities in access to care that are difficult to disentangle from discriminatory values and practice. Policy-makers in the United States, England and Scotland have recently begun to address these issues. It is recommended that a clear vision for health policy and strategies be created to address health disparities faced by persons with ID in Canada.

Regional variation in dental procedures among people with an intellectual disability, Ontario, 1995-2001.

BACKGROUND: The literature indicates that people with an intellectual disability have a prevalence of dental caries that is either lower than or similar to that of the general population. However, many of their caries go untreated, and extractions are more often used as a means of treatment than in the general population. A substantial percentage (40%) of day admissions to hospital of people with intellectual disabilities in Ontario is related to dental diseases. In this paper, we examine whether rates of in-hospital dental procedures are evenly distributed across Ontario and discuss possible explanations for the findings. MATERIALS AND METHOD: A retrospective analysis was made of routinely collected hospital admission data for people with an intellectual disability. Age- and gender-adjusted rates for dental procedures were calculated using the direct method of adjustment and 1996 census population estimates of Ontario. Three different summary measures for the assessment of regional variation were used. RESULTS: Two areas had dental procedure rates among those with an intellectual disability that were significantly lower than the overall Ontario rate: Hamilton-Wentworth and Quinte-Kingston and Rideau. The 3 district health council areas with the highest rates for dental procedures were Niagara, Essex-Kent and Lambton, and Durham-Haliburton-Kawartha and Pine Ridge; all 3 rates were higher than the overall Ontario rate. CONCLUSIONS: The use of day surgery and in-hospital visits to treat dental diseases in people with an intellectual disability varies considerably by region in Ontario. Observed differences may indicate inequities.
