Alberta's Data and Analytic Strategy: Leveraging Linked Data to Drive Innovation

Background The Province of Alberta, Canada, maintains a mature data environment with linkable administrative and clinical data dating back up to 30 years. Alberta has a single payer, publicly funded and administered, universal health system, which maintains multiple administrative data sets. Main Aim The main aim of the strategy is to fully maximize the data assets in the province to drive health system health system innovation, with a focus on improving health outcomes and quality of life. Methods/Approach The Alberta Ministry of Health has created the Secondary Use Data Access (SUDA) initiative to leverage its administrative health data. SUDA envisions strengthening partnerships between the public and private sectors through two main data access approaches. The first is direct access to de-identified data held within the Alberta Health data warehouse by key health system stakeholders (e.g. academic institutions, professional associations, regulatory colleges). The second is indirect access to private and not-for-profit organizations, using a data access safe haven (DASH) approach. Indirect access is achieved through private sector investments to a trusted third party that hires analysts placed within the Ministry of Health offices. Results Staffing agreements and privacy impact assessments are in place. Indirect access includes a multiple stakeholder steering committee to vet and prioritize projects. Private and not-for-profit stakeholders do not have access to raw data, but rather receive access to aggregated data and statistical models. All data disclosures are done by Ministry staff to ensure compliance with Alberta's Health Information Act. Direct access has been established for one professional organization and one academic institution, with access restricted to de-identified data. Conclusion The Secondary Use Data Access initiative uses a safe haven approach to leveraging data to provide a more secure approach to data access. It reduces the need to provision data outside of the data warehouse while improving timely access to data. The approach provides assurances that people's health information is held secure, while also being used to create health system improvements

Alberta's Data Mobilization Strategy: Leveraging Linked Data for Innovation

Introduction The Province of Alberta maintains a mature data ecosystem with linkable data dating back over 30 years. The population-based nature of the data makes this a valuable asset for driving analytics to support health system innovation, with a focus on improving health outcomes and quality of life. Objectives and Approach Alberta Health has created the Secondary Use Data Access (SUDA) initiative to leverage its administrative health data. SUDA envisions strengthening partnerships between the public and private sectors with two main access approaches. The first is direct access to de-identified data held within the Alberta Health data warehouse by key health system stakeholders (e.g. academic instituions, Health Quality Council of Alberta, regulatory colleges). The second is indirect access to private and not-for-profit stakeholders, using a safe haven approach. Indirect access is achieved through private sector investments to a trusted third party that hires analysts to be placed within Alberta Health. Results Staffing agreements and privacy impact assessments have been drafted to support the work. The indirect access route includes a multiple stakeholder steering committee to vette and prioritize projects. Private and not-for-profit stakeholders do not have access to the data, but rather receive access to aggregate data and statitstical models. All disclosures are done by Alberta Health staff to ensure compliance with Alberta's Health Information Act. Direct access has been established for the Alberta Medical Association as part of a long standing data sharing agreement, with access restricted to de-identified data only. To date, seven industry proposals for analytics have been received and are currently being actioned. Conclusion/Implications The Secondary Use Data Access initiative uses a safe haven approach to leveraging data. It reduces the need to provision data outside of the data warehouse and allows for better monitoring of access and use of data. The approach provides assurances that people's health information is secure

The Long-Baseline Neutrino Experiment: Exploring Fundamental Symmetries of the Universe

The preponderance of matter over antimatter in the early Universe, the dynamics of the supernova bursts that produced the heavy elements necessary for life and whether protons eventually decay --- these mysteries at the forefront of particle physics and astrophysics are key to understanding the early evolution of our Universe, its current state and its eventual fate. The Long-Baseline Neutrino Experiment (LBNE) represents an extensively developed plan for a world-class experiment dedicated to addressing these questions. LBNE is conceived around three central components: (1) a new, high-intensity neutrino source generated from a megawatt-class proton accelerator at Fermi National Accelerator Laboratory, (2) a near neutrino detector just downstream of the source, and (3) a massive liquid argon time-projection chamber deployed as a far detector deep underground at the Sanford Underground Research Facility. This facility, located at the site of the former Homestake Mine in Lead, South Dakota, is approximately 1,300 km from the neutrino source at Fermilab -- a distance (baseline) that delivers optimal sensitivity to neutrino charge-parity symmetry violation and mass ordering effects. This ambitious yet cost-effective design incorporates scalability and flexibility and can accommodate a variety of upgrades and contributions. With its exceptional combination of experimental configuration, technical capabilities, and potential for transformative discoveries, LBNE promises to be a vital facility for the field of particle physics worldwide, providing physicists from around the globe with opportunities to collaborate in a twenty to thirty year program of exciting science. In this document we provide a comprehensive overview of LBNE's scientific objectives, its place in the landscape of neutrino physics worldwide, the technologies it will incorporate and the capabilities it will possess.Comment: Major update of previous version. This is the reference document for LBNE science program and current status. Chapters 1, 3, and 9 provide a comprehensive overview of LBNE's scientific objectives, its place in the landscape of neutrino physics worldwide, the technologies it will incorporate and the capabilities it will possess. 288 pages, 116 figure

Emergence and Spread of the SARS-CoV-2 Omicron Variant in Alberta Communities Revealed by Wastewater Monitoring

Wastewater monitoring of SARS-CoV-2 allows for early detection and monitoring of COVID-19 burden in communities and can track specific variants of concern. Targeted assays enabled relative proportions of SARS-CoV-2 Omicron and Delta variants to be determined across 30 municipalities covering >75% of the province of Alberta (pop. 4.5M) in Canada, from November 2021 to January 2022. Larger cities like Calgary and Edmonton exhibited a more rapid emergence of Omicron relative to smaller and more remote municipalities. Notable exceptions were Banff, a small international resort town, and Fort McMurray, a more remote northern city with a large fly-in worker population. The integrated wastewater signal revealed that the Omicron variant represented close to 100% of SARS-CoV-2 burden prior to the observed increase in newly diagnosed clinical cases throughout Alberta, which peaked two weeks later. These findings demonstrate that wastewater monitoring offers early and reliable population-level results for establishing the extent and spread of emerging pathogens including SARS-CoV-2 variants.Alberta Healt

A cluster randomized controlled trial comparing three methods of disseminating practice guidelines for children with croup [ISRCTN73394937]

Background: The optimal management of croup – a common respiratory illness in young children – is well established. In particular, treatment with corticosteroids has been shown to significantly reduce the rate and duration of intubation, hospitalization, and return to care for on-going croup symptoms. Furthermore treatment with a single dose of corticosteroids does not appear to result in any significant adverse outcomes, and yields overall cost-savings for both families and the health care system. However, as has been shown with many other diseases, there is a significant gap between what we know and what we do. The overall aim of this study is to identify, from a societal perspective, the costs and associated benefits of three strategies for implementing a practice guideline that addresses the management of croup. Methods/designs: We propose to use a matched pair cluster trial in 24 Alberta hospitals randomized into three intervention groups. We will use mixed methods to assess outcomes including linkage and analysis of administrative databases obtained from Alberta Health and Wellness, retrospective medical chart audit, and prospective telephone surveys of the parents of children diagnosed to have croup. The intervention strategies to be compared will be mailing of printed educational materials (low intensity intervention), mailing plus a combination of interactive educational meetings, educational outreach visits, and reminders (intermediate intensity intervention), and a combination of mailing, interactive sessions, outreach visits, reminders plus identification of local opinion leaders and establishment of local consensus processes (high intensity intervention). The primary objective is to determine which of the three intervention strategies are most effective at lowering the rate of hospital days per 1,000 disease episodes. Secondary objectives are to determine which of the three dissemination strategies are most effective at increasing the use of therapies of known benefit. An economic analysis will be conducted to determine which of the three intervention strategies will most effectively reduce total societal costs including all health care costs, costs borne by the family, and costs stemming from the strategies for disseminating guidelines.Science, Faculty ofStatistics, Department ofOther UBCReviewedFacult

Increasing rates of diabetes amongst status Aboriginal youth in Alberta, Canada

Objectives. To track and compare trends in diabetes rates from 1995 to 2007 for Status Aboriginal and general population youth. Study design. Longitudinal observational research study (quantitative) using provincial administrative data. Methods. De-identified data was obtained from Alberta Health and Wellness administrative databases for Status Aboriginal (First Nations and Inuit people with Treaty status) and general population youth (<20 years). Diabetes cases were identified using the National Diabetes Surveillance System algorithm. Crude annual diabetes prevalence and incidence rates were calculated. The likelihood of being a prevalent case and incident case of diabetes for the 2 populations was compared for the year 2007. Average Annual Percent Changes (AAPC) in prevalence and incidence from 1995 to 2007 were determined and compared between the 2 groups to examine trends over time. Results. While the prevalence of diabetes was higher in the general population in 1995, by 2007 there were no between group differences, reflected in the significantly higher AAPC of 6.98 for Status Aboriginal youth. Status Aboriginal males had a lower diabetes risk in 1995 compared with females, and experienced a greater increase in prevalence over the 13 years (AAPC 9.18) so that by 2007 their rates were equivalent to those of the females. Differences in diabetes incidence trends were only observed among male youth, where increases in incidence were greater for Status Aboriginal (AAPC 11.65) compared to general population males (AAPC 4.62) (p = 0.03). Conclusion. Youth-onset diabetes is an increasing problem in Alberta, especially among young Status Aboriginal males
