Impact of Users’ Experience with a Web-Based Reporting Portal on Timeliness and Quality of Reporting

The New York City Department of Health and Mental Hygiene’s (NYC DOHMH) Division of Disease Control (DDC) conducts surveillance of more than 90 specific diseases and conditions and relies on both provider reports and electronic laboratory reports for data. While laboratory reports provide vital laboratory data and represent the majority of the surveillance data that DOHMH receives, they are not always timely or sufficient to confirm a case. Provider reports, in contrast, contain data often not available in laboratory reports and can be more prompt than laboratory reports.

Improving Timeliness of Georgia Emergency Room Data

Timeliness of emergency room (ER) data is arguably its strongest attribute in terms of its contribution to disease surveillance. Timely data analyses may improve the efficacy of prevention and control measures. There are a number of studies that have looked at timeliness prior to the advent of Meaningful Use, and these studies note that ER data were not fast enough for them to be useful in real time2,3. However, the change in messaging practices in the Meaningful Use era potentially changes this.

Implementation of Integrated Disease Surveillance and Response (IDSR) in Swaziland

Swaziland adopted the Integrated Disease Surveillance and Response (IDSR) strategy in 2010 to strengthen Public Health Surveillance (PHS) that fulfills International Health Regulations (2005) and the Global Health Security Agenda (GHSA). This strategy allows the Ministry of Health (MoH), Epidemiology and Disease Control Unit (EDCU) to monitor, prevent and control priority diseases in the country. We used a health systems strengthening approach to pilot an intervention model for IDSR implementation at five hospitals in Swaziland over a pilot phase of three months.

Inconsistency of Timeliness in a Chief Complaint-Based Syndromic Surveillance System During Two Influenza Epidemic Seasons

Syndromic surveillance system has been developed and implemented all over the world, and many studies showed that syndromic data sources had improved timeliness towards traditional surveillance method in the early warning of some infectious disease epidemics. However, owing to the uncertainties of disease epidemic features, clinical manifestations and population behaviors, the early warning timeliness of syndromic data sources might change across time and population, and few studies had explored their consistency in different epidemic periods of infectious diseases.

Timeliness of Chlamydia Laboratory and Provider Reports: A Modern Perspective

Timeliness of reports sent by laboratories and providers is a continuous challenge for disease surveillance and management. Public health organizations often collect communicable disease reports with various degrees of timeliness raising the concern about the delay in patient information received. Timely reports are beneficial to accurately evaluate community health needs and investigate disease outbreaks. According to Indiana state law, chlamydia reports are required to be sent to public health within 3 days after a positive test result confirmation.

Evaluating the Performance of Syndromic Surveillance System using High-fidelity Outbreak Simulations

The evaluation of outbreak detection performance remained a major challenge to every syndromic surveillance system. Owing to the scarcity and uncertainty of infectious disease outbreaks in the real world, simulated outbreak datasets have been commonly used by scholars for performance evaluation. Although this method was powerful in estimating the performance of syndromic surveillance across a variety of outbreak scenarios, the inevitable differences between simulation and authentic outbreak event limited its external validity.

An Experimental Study Using Opt-in Internet Panel Surveys for Behavioral Health Surveillance

Today, surveyors in both the private and public sectors are facing considerable challenges with random digit dialed (RDD) landline telephone samples. The population coverage rates for landline telephone surveys are being eroded by wireless-only households, portable telephone numbers, telecommunication barriers (e.g., call forwarding, call blocking and pager connections), technological barriers (call-blocking, busy circuits) and increased refusal rates and privacy concerns.

Category-Specific Comparison of Univariate Alerting Methods for Biosurveillance Decision Support

Temporal alerting algorithms commonly used in syndromic surveillance systems are often adjusted for data features such as cyclic behavior but are subject to overfitting or misspecification errors when applied indiscriminately. In a project for the Armed Forces Health Surveillance Center to enable multivariate decision support, we obtained 4.5 years of outpatient, prescription and laboratory test records from all US military treatment facilities.

MoH+: A Global, Integrated, and Automated View of Official Outbreak Reporting

Previous studies have documented significant lags in official reporting of outbreaks compared to unofficial reporting (1,2). MoH+ provides an additional tool to analyze this issue, with the unique advantage of actively gathering a wide range of streamlined official communication, including formal publications, online press releases, and social media updates.

Influenza mortality surveillance using a statewide electronic death registration system F Nebraska, 2009–2010

Public health surveillance using death data is critical for tracking the impact of diseases such as influenza. However, utility of such systems is compromised by delayed reporting, particularly when it is paper based. In Nebraska, funeral directors are encouraged to initiate death certificates electronically by an electronic death registration system (EDRS). Although paper-based or mixed (electronic followed by paper) registration is still accepted statewide, EDRS usage has gradually increased over time.
