Data Source Descriptions

Mortality: Data on causes of death come from a database of death certificate information, collected and maintained by the Minnesota Department of Health (MDH) Center for Health Statistics and the Centers for Disease Control and Prevention (CDC), National Center for Health Statistics.

The primary cause of death is indicated by an International Classification of Diseases (ICD) code.  The ICD is designed to promote international comparability in the collection, processing, classification, and presentation of mortality statistics.  This includes providing a format for reporting causes of death on the death certificate.  The reported conditions are translated into medical codes through the use of classification structure and the selection and modification rules contained in the applicable version of the ICD, published by the World Health Organization.  The single selected cause for tabulation is called the underlying cause of death.  The 9th revision of the ICD was used from 1979-1998 and the 10th revision has been in effect since 1999.

Risk Factors: The primary source of statewide data on cardiovascular disease prevalence and risk factors is the Behavioral Risk Factor Surveillance System (BRFSS) Survey, conducted by the Minnesota Department of Health.  The BRFSS Survey is designed to measure health risk behavior in the non-institutionalized adult (aged 18 years or older) population.  The survey is a collaborative project of the Centers for Disease Control and Prevention (CDC) and health departments from states and territories.  Statewide prevalence estimates for heart attack (myocardial infarction), coronary heart disease and angina, stroke, and several cardiovascular disease-related behaviors and risk factors are derived from this survey, including high blood pressure, high blood cholesterol, overweight and obesity, cigarette smoking, poor dietary habits, and physical inactivity.  In some years the survey asks about personal awareness of the signs and symptoms of heart attack and stroke, and utilization of rehabilitation services after having a heart attack or stroke.

Adolescents: Statewide data on cardiovascular disease risk factors in school-age children come from the Minnesota Student Survey, conducted every three years as the result of a collaboration between Minnesota schools and the Minnesota Departments of Education, Employment and Economic Development, Health, Human Services, and Public Safety.  This voluntary written survey includes students in 6th, 9th, and 12th grade.  This report includes data from the 2001, 2004, 2007, and 2010 surveys.

Quality: Minnesota's 2008 Health Reform Law requires the Commissioner of Health to establish a standardized set of quality measures for health care providers across the state. These quality measures are reviewed annually, and based on medical evidence and developed through a process in which health care providers participate. The risk-adjusted measures are reported annually.

Statewide data on the quality of inpatient hospital care for heart disease come from the National Healthcare Quality Report (NHQR) and the National Healthcare Disparities Report (NHDR), produced by the Agency for Healthcare Research and Quality (AHRQ) at the US Department of Health & Human Services.  These summary measures of quality of care include hospital measures of care for five clinical conditions, including heart disease and are available by state through annual state snapshots which compare statewide performance to regional and national performance.

SHAPE: The Survey of the Health of Adults, the Population and the Environment (SHAPE) is a health surveillance project that monitors the health of adults in Hennepin County, Minnesota’s most populated county. Data from this project include important information from racial and ethnic communities. The information in this survey include questions concerning key health indicators; CVD-related data include prevalence of heart trouble or angina (heart disease), physical activity, dietary habits, cigarette smoking, high blood pressure, high blood cholesterol, overweight and obesity, and diabetes.

Health Plan Employer Data and Information Set (HEDIS): The Health Plan Employer Data and Information Set (HEDIS) is a set of data collection indicators developed to assist purchasers of health care (such as employers or the state government) in evaluating the effectiveness of care provided to health plan enrollees. Minnesota HMOs are required to collect data and report on standard clinical performance measures developed by the National Committee for Quality Assurance. Methodologies utilized by HMOs for data collection include administrative records (claims) or medical record audits.
