Why Data? Epidemiology and Evaluation
The Montana Diabetes Program (MDP) collects, analyzes and reports data from many different sources to help the people of Montana understand the complexities of prediabetes and diabetes and make the best decisions for their health. Staff with a variety of expertise help with this work using skills from many different disciplines:
Public Health Terminology
|ADJUSTED MORTALITY RATE||A mortality rate statistically modified to eliminate the effect of different age distributions in the different populations.|
|BIAS||Deviation of results or inferences from the truth, or processes leading to such systematic deviation. Any trend in the collection, analysis, interpretation, publication, or review of data that can lead to conclusions that are systematically different from the truth.|
|CONFIDENCE INTERVAL||A range of values for a variable of interest, e.g., a rate, constructed so that this range has a specified probability of including the true value of variable. The specified probability is called the confidence level, and the end points of the confidence interval are called the confidence limits.|
|INCIDENCE RATE||A measure of the frequency with which an event, such as a new case of illness, occurs in a population at risk; the numerator is the number of new cases occurring during a given time period.|
|PREVALENCE||The number of proportion of cases or events or conditions in a given population.|
How common is diabetes and prediabetes?
- About 64,000 Montana adults currently have diagnosed diabetes. 1
- Across the US, the number of people diagnosed with diabetes increased from 1.5 million in 1958 to 26.9 million in 2018. 2
Annual Diabetes in Montana Infographic, 2019
- In 2017, 7.4% of Montana adults reported having prediabetes. 1
- Many more adults are estimated to have prediabetes, but not know it. In Montana, it is estimated that over 1 in 3 (37.4%) adults have prediabetes. 3
- Across the US, it is estimated that 88 million adults (34.5% of the adult US population) aged 18 years or older have prediabetes. 2
GIS and Spatial Analysis
MDP staff utilizes GIS software and tools such as ArcGIS Pro and ArcGIS Online to create maps and other visualizations with diabetes related datasets.
- Story maps: GIS tool to help create stories with text, interactive maps, pictures, and other multimedia content to share with a wide audience.
- ArcGIS Hub: Hub allows users to follow our program for updates and it gives them access to free accounts and Geospatial applications they can apply to their own work. Once signed up, users can directly collaborate with the MDP.
Where do we get our information about pre-diabetes and diabetes?
The Montana Diabetes Program uses many data sources for diabetes surveillance, evaluation, and decision making. Our goal is to benefit all Montanans by helping to prevent and reduce diabetes complications.
Check out the list of data sources below. You can also access the Public Health Data Resource Guide to learn more. It is important to remember that data sets don't contain information that can identify individuals.
- Behavioral Risk Factor Surveillance System (BRFSS) - To get this data, health related questions are asked of 400,00 adults in the United States by telephone every year.
- Montana Vital Statistics - Collects and analyzes data on vital events in Montana, including public information about all births and deaths.
- Montana Hospital and Emergency Department Discharge Data System - Analyzes information from the Montana Hospital Association's inpatient hospitalization data set to provide summary statistics and other reporting.
- Electronic Diabetes Quality Care Monitoring System (E-DQCMS) - an electronic registry to support diabetes related quality improvement efforts.
- Centers for Disease Control and Prevention (CDC) - The national public health agency of the United States.
- Centers for Medicare and Medicaid (CMS) Medicare Chronic Conditions Dashboard - provides information on the prevalence, utilization, and Medicare spending for beneficiaries with chronic conditions, including diabetes.
- American Diabetes Association (ADA) Statistics about Diabetes - Gives overall national statistics on diabetes, including diabetes prevalence, complications/co-morbid conditions, and cost of diabetes.
The DPHHS website is being redesigned and will be moved to a new platform in July.
Please be aware that some bookmarks to the DPHHS site may need to be updated after the move.
Thank you for your patience while we complete this move.
Montana Quick Stats
The Montana Quick Stats provides quick access to statistics with short description on topics related to diabetes.
These reports aim to increase the understanding of data related to diabetes prevention, education, and management as well as provides clinical recommendation to the health care community.
These reports are evaluations done by the Montana Diabetes program related to diabetes in Montana.
Special Reports and Presentations
MDP staff often participate in regional and national conferences and share data related to diabetes and its complications in oral and poster presentations. These reports and presentation cover variety of topics related to diabetes. Please contact the MDP to inquire about what other data may be available.
