Manitoba First Nation peoples' use of hospital-based mental health services: Trends and solutions

Lavoie JG, Phillips-Beck W, Kinew KA, Katz A

Rates of hospitalization for mental health are increasing for First Nation males and females. This is particularly evident for those affiliated with the Island Lake and Keewatin Tribal Councils. The length of stay has increased. Changes in rates of readmissions were not statistically significant. First Nations are admitted for mental health conditions at a younger age when compared with other Manitobans, and trends show that the First Nations` average age at admission is decreasing.


Overlap between child protection services and the youth justice system: Protocol for a retrospective population-based cohort study using linked administrative data in Manitoba, Canada

Nickel NC, Turnbull L, Wall-Wieler E, Au W, Ekuma O, MacWilliam L, Enns JE, Lee JB, McCulloch S, Burchill C, Brownell M

Children who have a history of involvement in child protection services are over-represented in the youth and adult criminal justice systems. There are significant health and socioeconomic implications for individuals involved in either or both child protection services and the justice system. Understanding the 'overlap' between these two systems would provide insight into the health and social needs of this population. This protocol describes a research programme on the relationship between the child welfare and the youth justice systems, looking specifically at the population involved in both child protection services and the youth justice system. We will examine the characteristics associated with involvement in these systems, justice system trajectories of individuals with a history of child protection services` involvement and early adult outcomes of children involved in both systems.


The Differential Effect of an Obesity Prevention Program for School-Aged Children: Subgroup Analysis of a Cluster Randomized Controlled Trial

Nickel N, Doupe M, Enns JE, Brownell M, Burland E, Chartier M, Chateau D, Crockett L, Katz A, Santos R, Sarkar J

Childhood obesity rates can vary substantially between male and female children and across different socio-economic groups and geographical regions. This deliverable looked at the effects of the Healthy BuddiesTM curriculum and found that the Healthy BuddiesTM curriculum was most effective in boys and children living in lower income neighborhoods or urban areas. As well, improved health behavior outcomes among urban and rural subgroups in the intervention arm were largely driven by children living in urban areas. These findings highlight opportunities to enhance the Healthy BuddiesTM curriculum to more broadly improve participants ‘health and to ensure it is relevant for all subgroups of children.

HDRN Canada Announces New Partnership with CanPath to Enable Data Linkage 

Network Canada (HDRN Canada) and the Canadian Partnership for Tomorrow’s Health (CanPath) have announced a new partnership that will enable linkage between CanPath cohort data and health data held at provincial and territorial data centres. Through this new partnership, researchers will now be able to submit requests for multi-jurisdictional research projects using CanPath data through HDRN Canada’s Data Access Support Hub (DASH). HDRN Canada and CanPath can support research teams interested in leveraging linked data, including COVID-19 related data from CanPath’s COVID-19 Questionnaire and provincial data centres where available, for Fall 2020 CIHR Project Grant proposals and research projects. We can also support funding applications by providing Letters of Support.




Revisiting Primary Care Provider Projection Models

Katz A, Chateau D, Taylor C, Koseva I


The 2009 MCHP Deliverable, Physician Resource Projection Models, developed a novel methodology for predicting resource needs for family doctors for Manitoba. The projections were based on previous patterns of services provided by family physicians over 30 years and population projections for Manitoba as a whole for 2015 and 2020.

This deliverable validated the methodology by comparing the projections to the current reality. Updated analyses add nurse practitioners to the models as well as analyses at the local level with projections to 2025.


Type 2 Diabetes in Manitoba

Ruth C, Sellers E, Chartrand C, McLeod L, Prior H, Sirski M, Dragan R, Chen H, McDougall C, Schultz J


This deliverable, undertaken in partnership with The First Nation Health and Social Secretariat of Manitoba provides an analysis of trends in incidence and prevalence of for all types of non-gestational diabetes from the 1985 to 2017 allowing comparison to national and international statistics. Then, using the wealth of data within the Repository, especially the Diabetes Education Resource for Children and Adolescents (DER-CA) clinical database, Manitobans diagnosed with type 2 diabetes mellitus (T2DM) were identified and their outcomes over the last 6 years were described. This includes diabetes control, complications, mortality and health service use including hospitalizations, continuity of primary care and specialist care. Multiple analyses were undertaken to examine whether the care received by Manitobans living with T2DM met current guidelines. There are also a number of special analyses in cohorts of people matched to those without diabetes for childhood onset T2DM, T2DM in pregnancy, and for mental health outcomes in adults. Information is presented for different age groups, by sex, by health region and by Tribal Council Area and results were compared between registered First Nation Manitobans and all other Manitobans.


Immigration Data Linkage


Immigration is a key dimension of the Canadian population dynamics. However, little is known about the characteristics of immigrants to Manitoba, as well as their social and health outcomes. The addition of the Immigration, Refugees and Citizenship Canada permanent resident database into the Manitoba Population Research Data Repository (Repository) at MCHP is the first step in addressing these gaps. The deliverable documented the linkage methodology used, evaluated potential biases in the linkage, and illustrated the potential for research using these data. Finally, basic primary care and death indicators have been used to compare immigrants versus non-immigrants.
