Population Health Surveillance

The CVC is actively involved in examining population-level issues related to access, delivery, treatment, and outcomes of heart disease in Alberta and Canada. Healthcare administrative databases have become a cornerstone in the process of assessing performance and providing feedback to improve quality of health care delivery at a population-level. The integrated system of health care delivery in Alberta, with one centralized provider and one payer, has facilitated the linking of inpatient, outpatient (including ED), ambulance, pharmaceutical, and laboratory data at the patient level. The volume of data generated by linking the health care databases to environment, census, and other databases (see figure) has brought us into the wider realm of “big-data”.

The CVC has one of the largest repositories of cardiovascular data at the University of Alberta.  This repository currently includes data on approximately 6.5 million hospitalizations for 2.5 million Canadians, and data on hospitalizations, outpatient care, medications, and vital status for over 900,000 Albertans suffering from heart disease over the last decade.  Our extensive portfolio of research using these data includes the following:

Our extensive portfolio of research using these data includes the following:

  • Trends in incidence and prevalence of specific cardiovascular conditions (acute coronary syndormes, heart failure, atrial fibrillation, congenital heart disease, syncope, etc)
  • Socio-economic and urban/rural differences in access to treatment and outcomes
  • Outcomes among vulnerable populations such as women and children, the elderly, ethnic minorities, and status aboriginal patients
  • Association of risk factors and use of evidence-based therapies on long-term outcomes
  • Impact alternative care patterns on outcomes
  • Impact of environmental and social factors on patient outcomes
  • Resource utilization and costs of care
  • Validity and reliability of disease coding
  • Novel methods to risk stratify patients
