Asthma Surveillance & Epidemiology

Surveillance activities are one of five Infrastructure strategies under CDC’s Cooperative Agreement (CA) on comprehensive asthma control (2014-2019). Under the Cooperative Agreement, the goal of Surveillance Infrastructure strategy is to maintain and enhance a statewide surveillance system, collect and analyze asthma-related data, and identify populations disproportionately affected by asthma.

Moreover, the purpose of the Connecticut Asthma Program (CAP), Asthma Surveillance & Epidemiology team, is to provide the most recent and reliable data on Connecticut’s high-risk populations for asthma, identify asthma-related health disparities, and trends that stakeholders can use to help them guide program initiatives, rationalize intervention and develop custom local intervention/programs to target the most at-risk, to monitor progress toward Healthy People 2020 objectives and overall, to decrease the burden of asthma in Connecticut.

Statistics include prevalence rates tables for adult and children with current or lifetime asthma from the Behavioral Risk Factor Surveillance System (BRFSS); hospitalization and emergency department acute rates for adult and children from the Connecticut Hospital Information Management Exchange (CHIME) and Mortality rates based on the Connecticut Vital Records Registry data. 

Reports are comprehensive documents that gather information from different sources specifically produced for a better insight of the burden of asthma in Connecticut or produced after a statutorily mandate for descriptive purposes of asthma in Connecticut schools.

Data Briefs & Fact Sheets are targeted estimates on specific subjects, such as estimates of asthma prevalence among the youth based on the Connecticut Youth Tobacco Survey data; Hospital Healthcare Utilization across Selected Geographic Designations or the Asthma Fact Sheet for the five Largest Cities in Connecticut based on the Connecticut Hospital Information Management Exchange (CHIME) data.

Maps are produced using geocodable data from the Connecticut Health Information Exchange and the Connecticut Asthma Program.
