Comparison between HL7 and Legacy Syndromic Surveillance Data in New York City

Data from the Emergency Departments (EDs) of 49 hospitals in New York City (NYC) is sent to the Department of Health and Mental Hygiene (DOHMH) daily as part of the syndromic surveillance system. Currently, thirty-four of the EDs transmit data as flat files. As part of the Center for Medicare and Medicaid Services Electronic Health Record Incentive Program, otherwise known as Meaningful Use, many EDs in our system have switched or are in the process of switching to HL7 Messaging Standard Version 2.5.1.

Comparison of ILINet and ESSENCE for Influenza Surveillance at the Local Level

ILINet is used nationwide by sentinel healthcare providers for reporting weekly outpatient visit numbers for influenza-like illness to CDC. The Florida Department of Health receives urgent care center (UCC) data through ESSENCE from participating facilities. Seminole County is unique in that its four sentinel providers located in separate UCCs report into both systems, and all their discharge diagnoses are available through ESSENCE.

Determining Disease Load through the National Health Information System in Pakistan

Before the launch of standard National Health Information System (NMHIS) in 2000, there had been acute paucity of reliable and timely health information in Pakistan. Health Departments had no choice than to resort to estimates or carry expensive community based surveys to determine the disease incidence. After the development and deployment of NHMIS, overall Health System is reshaping itself based upon the regular and frequent information now available on a good number number of priority health problems.

Development of an Infectious Disease Surveillance Framework at Public Health Ontario

Since its inception in 2008, PHO has grown through new funding to establish the agency, as well as a series of program transfers from the Government of Ontario, including ID surveillance. PHO’s current role in ID surveillance in Ontario is to support the public health and health care systems with surveillance information, tools, and resources for the prevention and control of IDs. PHO also provides scientific and technical expertise for IDs, including different aspects of surveillance (e.g., data entry requirements, statistical algorithms, provincial surveillance reports).

Development of Mental Health Classification Related to Severe Weather Events

Real-time emergency department (ED) data are currently received from 78 of 80 New Jersey acute care and satellite EDs by Health Monitoring Systems Inc.’s (HMS) EpiCenter system. EpiCenter collects, manages and analyzes ED registration data for syndromic surveillance, and provides alerts to state and local health departments for surveillance anomalies.

Community Engagement among the BioSense 2.0 User Group

BioSense 2.0 has become a platform for technical receipt and analysis of syndromic surveillance data for many jurisdictions nationwide, as well as a collaborative effort that has engaged a larger community of syndromic surveillance practitioners, Governance Group, and federal agencies and organizations. The potential longterm benefits of BioSense 2.0 for resource and data sharing have at times been overshadowed by the short-term limitations of the system and disconnected efforts among the CoP.

Accrued – An R Package for Visualizing Data Quality for Aggregate Surveillance Data

The utility of specific sources of data for surveillance, and the quality of those data, are an ingoing issue in public health(1). Syndromic surveillance is typically conducted as a secondary use of data collected as part of routine clinical practice, and as such the data can be of high quality for the clinical use but of lower quality for the purpose of surveillance. A major data quality issue with surveillance data is that of timeliness. Data used in surveillance typically arrive as a periodic process, inherently creating a delay in the availability of the data for surveillance purposes.

Challenges of ELR Implementation: Moving Toward Semantic Understanding through Vocabulary Validation

Meaningful Use has increased interest in submission of ELR to public health agencies, prompting these agencies to analyze their reporting process. Tennessee’s reporting regulations require anyone with knowledge of or suspecting a reportable disease or event report to the local health department. Although it is understood that laboratories are more diligent and routine reporters, focus in listing of these events is from the healthcare provider perspective. Public health agencies must acknowledge the differences in provider case reporting and laboratory result reporting.

Evaluating Notifiable Disease Reporting by Providers: Analysis of Data Element Completeness

Completeness of public health information is essential for the accurate assessment of community health progress and disease surveillance. Yet challenges persist with respect to the level of completeness that public health agencies receive in reports submitted by health care providers. Missing and incomplete data can jeopardize information reliability and quality resulting in inaccurate disease evaluation and management (1). Additionally, incomplete data can prolong the time required for disease investigators to complete their work on a reported case.

Under-ascertainment of Illness due to Influenza in Administrative Databases, a Population-based Record Linkage Study

Under-ascertainment of severe outcomes of influenza infections in administrative databases has long been recognised. After reviewing registered deaths following an influenza epidemic in 1847, William Farr, of the Registrar-General's Office, London, England, commented: ''the epidemic carried off more than 5,000 souls over and above the mortality of the season, the deaths referred to that cause [influenza] are only 1,157"[1].
