Public health tracking of diabetes is an essential part of reducing the disease burden in Connecticut, identifying high-risk groups, formulating sensible health care policy, and evaluating our state's progress in preventing this disease.
The objective of the Connecticut Diabetes Surveillance System (CDSS) is to provide timely and relevant information about diabetes and its complications in Connecticut, as well as related risk factor information. CDSS provides support to the Connecticut Diabetes Prevention and Control Program, a CDC-funded program within the Connecticut Department of Public Health. The links below provide current information regarding Connecticut deaths and hospitalizations due to diabetes and diabetes-related conditions, diabetes prevalence data, and related reports.

Diabetes Quality of Care and Maintenance in New England: Can Cross-State Collaboration Move Us Forward? (2018) - This  interstate analysis of Behavioral Risk Factor Surveillance System (BRFSS) data demonstrates that inadequate annual diabetes care among adults with diagnosed diabetes was endemic even in a relatively advantaged US census division, and traditional disparities (e.g., race/ethnicity, federal poverty level bracket) only partially explained patterns in diabetes maintenance activities.
