Older Adults with Dementia and Their Use of Acute Care Services in Alberta
Linking CPCSSN and administrative data will allow this team to produce reliable estimates of acute and long-term care use by older adults with dementia and identify risk factors for unplanned health care transitions.
Paediatric Asthma in Canada: An Epidemiological and Retrospective Cohort Study
This study’s aim is to apply the case definition for pediatric asthma in order to describe (1) the natural history of asthma and asthma-like symptoms, (2) the office-level management and (3) the effectiveness, side effects and safety of commonly used mediations for pediatric asthma in children in primary care.
Cholinesterase Inhibitor Prescribing in Primary Care
This study involves linking SAPCReN data with Alberta Health data to look at patterns of cholinesterase inhibitor prescribing in primary care clinics.
Identification of Frailty Using Administrative and Electronic Medical Record Data
The specific objectives of this study are to derive algorithms for frailty in community-dwelling seniors using administrative and electronic medical data and to validate these algorithms using primary care clinicians and patients. The differential risk of experiencing a hospital-related event will then be associated with natural ranges of frailty.
Pelvic Flood Disorders and Speech Disorders Case Definition Project
This study is focused on the development of case definitions for urinary incontinence, fecal incontinence, and pelvic organ prolapse using the CPCSSN database validated against the gold standard (chart review).
Diabetes Action Canada (DAC)
A secure data repository of de-identified clinical and social information about diabetic patients is being established for the purposes of national trials of preventative and therapeutic innovations. This project supports creating a ‘big data’ option for the purposes of public health surveillance and diabetes research, including data linkage and machine learning.
An Educational Intervention to Raise Family Physician Awareness of Alpha 1 Antitrypsin Deficiency (AATD) in the Canadian COPD Population
The objective of this project is to improve awareness, detection, and thus management of AATD, a genetically common but under recognized disease, among family physicians participating in SAPCReN.
Adult Asthma Case Definition Validation
The focus of this study is developing and validating a case definition for asthma in adult patients in primary care.
Hearing Loss in Older Adults in Canadian Primary Care: Development of a Case Definition
The aim of this study is to determine the prevalence of hearing loss in older adults by developing a case definition using SAPCReN data and to consider the prevalence of diabetes mellitus and dementia, two commonly reported comorbidities, in this population.
Department of Family Medicine Resident evaluation project
This project uses CPCSSN-AB data to measure patient outcomes for graduates of the University of Calgary Family Medicine program compared with graduates of other Canadian Family Medicine Residency programs.
Validation using CPCSSN Data Project
This study aims to show that CPCSSN data can effectively function as a reference standard when validating new case definitions, using the eight CPCSSN case definitions currently in use.
Lead by Dr. Scott Garrison, this pragmatic trial aims to enroll 8,750 community dwelling patients with hypertension to study medication timing. In particular, this project is designed to determine if switching the time of day blood pressure medications is taken to bedtime (compared to conventional morning use) reduces death, stroke, heart attack or hospital admission for congestive heart failure.
Complex Chronic Disease and High System Use
CPCSSN-AB and administrative data will be linked in order to investigate and characterize the clinical and socio-demographic profiles, resource use and health outcomes of primary care patients with complex chronic diseases.
Chronic Kidney Disease (CKD) Management in Primary Care
The aim of this project is to investigate current practice patterns of risk identification and to assess variation in patient, provider and regional level characteristics in the delivery of care, relative to established quality indicators.
Type 1 Diabetes Case Definition Validation
This study is focused on developing and validating a case definition for Type 1 diabetes using a machine learning approach. Furthermore, administrative and CPCSSN data will be linked for patients with diabetes and released to participating sentinels in the form of an interactive dashboard.
Risk factors for dementia in primary care settings
This PhD project is comparing the risk of developing dementia in seniors with and without cardiovascular disease risk factors.
Implementation of the CPCSSN Data Presentation Tool (DPT) in Primary Care Clinics
This project will further develop, implement and evaluate the CPCSSN DPT as a major resource for the production and distribution of primary care clinical data for public health surveillance and research.
Upcoming Projects/Research concepts
Incentivizing de-prescribing among primary care physicians.
Expectation Management and De-prescribing Trial
National Diabetes Complications Registry.
Chronic Kidney Disease Risk Assessment Tool for Renal Failure.
