Chronic diseases have a major impact on populations and healthcare systems worldwide. Administrative health data are an ideal resource for chronic disease surveillance because they are population-based and routinely collected. For multi-jurisdictional surveillance, a distributed model is advantageous because it does not require individual-level data to be shared across jurisdictional boundaries. Our objective is to describe the process, structure, benefits, and challenges of a distributed model for chronic disease surveillance across all Canadian provinces and territories (P/Ts) using linked administrative data. The Public Health Agency of Canada (PHAC) established the Canadian Chronic Disease Surveillance System (CCDSS) in 2009 to facilitate standardized, national estimates of chronic disease prevalence, incidence, and outcomes. The CCDSS primarily relies on linked health insurance registration files, physician billing claims, and hospital discharge abstracts. Standardized case definitions and common analytic protocols are applied to the data for each P/T; aggregate data are shared with PHAC and summarized for reports and open access data initiatives. Advantages of this distributed model include: it uses the rich data resources available in all P/Ts; it supports chronic disease surveillance capacity building in all P/Ts; and changes in surveillance methodology can be easily developed by PHAC and implemented by the P/Ts. However, there are challenges: heterogeneity in administrative databases across jurisdictions and changes in data quality over time threaten the production of standardized disease estimates; a limited set of databases are common to all P/Ts, which hinders potential CCDSS expansion; and there is a need to balance comprehensive reporting with P/T disclosure requirements to protect privacy. The CCDSS distributed model for chronic disease surveillance has been successfully implemented and sustained by PHAC and its P/T partners. Many lessons have been learned about national surveillance involving jurisdictions that are heterogeneous with respect to healthcare databases, expertise and analytical capacity, population characteristics, and priorities.

Gout is associated with a high disease burden in older men and women. The cost is primarily attributable to hospitalization, probably due to the comorbidities associated with gout. As the majority of cases are managed by nonrheumatologists, it is important that guidelines for the diagnosis and treatment of gout are disseminated to and met by all physician groups.

This study found differences in the rate but not class of antidepressant prescribing in Nova Scotia and Australia. Antidepressant use increased in both areas over the time period. This may be due to increased exposure to marketing, promotion, education or different prescribing practices in Nova Scotia compared to Australia.

The application of these DUE criteria by pharmacists in hospital and community practice has the potential to improve utilization and dosing of this important class of medications for the management of the symptoms and progression of CHF.

There are significant controversies regarding rising antipsychotic prescription trends in children and adolescents. Many pharmacoepidemiology trend studies have been published, and interpretations of these data are helpful in explaining what is happening in prescribing practices, but not why these patterns exist. There is a lack of qualitative data in this area, and the experience of prescribing antipsychotics to children and adolescents has not been adequately researched. We conducted a qualitative study using an interpretive phenomenological analysis of physicians’ experiences of antipsychotic prescribing to children and adolescents. Prescribers participated in individual interviews and a focus group. We used a staged approach for data analysis of transcriptions. In all, 11 physicians including psychiatrists and general practitioners participated in our study. We identified themes related to context, role and identity, and decision-making and filtering. Struggles with health system gaps were significant leading to the use of antipsychotics as substitutes for other treatments. Physicians prescribed antipsychotics to youth for a range of indications and had significant concerns regarding adverse effects. Our results provide knowledge regarding the prescribers’ experience of antipsychotics for children and adolescents. Important gaps exist within the health system that are creating opportunities for the initiation and continued use of these agents.
