Data Submission


Reporting Requirements

The required reporting of Emergency Illnesses and Health Conditions by healthcare providers, which include healthcare facility managers, is done in accordance with the DPH’s annual List of Reportable Diseases, Emergency Illnesses and Health Conditions in a format approved by the Commissioner.  See Conn. Gen. Stat. §§ 19a-2a(9) and 19a-215(b).  EpiCenter is the Commissioner’s new approved format for the reporting of Emergency Illnesses and Conditions. 


Data Reporters

Eligible Hospitals will have the option to attest to active engagement for the Syndromic Surveillance PH measure OR exclude from the measure because DPH did not declare readiness for 2017 in the required time frame. DPH will accept data from emergency departments and hospital-affiliated urgent care centers. DPH declared readiness for the Syndromic Surveillance PH measure on October 31, 2016.


Eligible Professionals: DPH does not have the capability to accept syndromic surveillance data in a MU-compliant manner for EPs. EPs must exclude from the measure based upon the criteria that EPs “Operate in a jurisdiction for which no public health agency is capable of receiving electronic syndromic surveillance data from EPs in the specific standards required to meet the CEHRT definition at the start of the EHR Reporting Period.”42 CFR 495.22(e)(10)(i)(B)(2)(ii) and 42 CFR 495.22 (e)(10)(i)(C)(2)(ii); 42 CFR 495.22 (e)(10)(ii)(C)(2)(ii).
