Evaluation of REDCap as a Tool for Outbreak Data Management, Illinois, 2013-2014

The Research Electronic Data Capture (REDCap) application has been used to build and manage online surveys and databases in academic research settings. Public health agencies have begun to use REDCap to manage disease outbreak data. In addition to survey and database development, and data management and analysis, REDCap allows users to track data manipulation and user activity, automate export procedures for data downloads, and use ad hoc reporting tools and advanced features, such as branching logic, file uploading, and calculated fields.

Impact of Demographics on Healthcare Utilization

The Affordable Care Act (ACA) was promoted with two goals: expanding health insurance coverage and reducing healthcare costs. Expanded coverage is expected to partially reduce costs. Emergency department (ED) visits are costlier than comparable primary care physician visits. If uninsured patients use the local ED more often than insured patients with comparable conditions, insuring them may change usage and lower costs. Some reports in the literature do not fit this model of ED usage.

Tractable Use Cases for Collaboration in Public Health Surveillance

The mission of the ISDS TCC is to bridge the gap between the analytic needs of public health practitioners and the expertise of researchers from other fields for the enhancement of disease surveillance, including situational awareness of chronic as well as infectious threats and follow-up activities such as case linkage and contact tracing.

Modeling Spatial Heterogeneity with Excess Zeroes from School Absenteeism dSata

Absenteeism has been considered as a potential indicator for the early detection of infectious disease outbreaks in population, especially in primary schools. However, in practice this data are often characterized by an excess of zeros and spatial heterogeneity. In a project on integrated syndromic surveillance system (ISSC) in rural China, Random effect zero-inflated Poisson (RE-ZIP) model was applied to simultaneously quantify the spatial heterogeneity for “occurrence” and “intensity” on school absenteeism data.

Monitoring Acute Diarrhea via an Electronic Surveillance System in the Peruvian Navy

Syndromic surveillance can supplement diagnosis-based surveillance in resource-limited settings with limited laboratory infrastructure. Syndromic surveillance allows for early outbreak detection relative to traditional systems and enables community health monitoring during outbreaks. Monitoring and disease diagnosis can be strengthened using pre-diagnostic data and statistical algorithms to detect morbidity trends.

New Ways to Disseminate the US National Notifiable Disease Provisional Data

The NNDSS is a nationwide collaboration that enables all levels of public health (local, state, territorial, federal and international) to monitor, control, and prevent the occurrence and spread of state-reportable and nationally notifiable diseases and conditions. The NNDSS data are a critical source of information for monitoring disease trends, effectiveness of prevention and control programs, and policy development.

Surveillance of Cardio Vascular Risk Factors Among Patients Undergoing Coronary Artery Bypass Surgery

According to world health organization report 2011, coronary artery diseases are the number one cause of death globally: more people die annually from coronary artery diseases than from any other cause. An estimated 17.3 million people died from coronary artery diseases in 2008, representing 30% of all global deaths. Of these deaths, an estimated 7.3 million were due to coronary heart disease and 6.2 million were due to stroke.

Analytic Methodologies for Disease Surveillance Using Multiple Sources of Evidence

This presentation is for public health practitioners and methodology developers interested in using statistical methods to combine evidence from multiple data sources for increased sensitivity to disease outbreaks. Methods described will account for practical issues such as delays in outbreak effects between evidence types. Presented examples will include outbreaks from multiple years of authentic data as will as simulations. The ensuing discussions with attendees will explore the role and scope of multivariate surveillance for the situational awareness of public health monitors.

Project Tycho, Data for Health: Open Access to Newly Digitized U.S. Weekly Nationally Notifiable Disease Surveillance Data from 1888-Present

Background: Public health agencies in the United States such as the Public Health Service before 1950 and the Centers for Disease Control after 1950 have published nationally notifiable disease reports for cities and states every week since 1888 in journals such as the Public Health Reports and the Morbidity and Mortality Weekly Report. Because most of these reports have been publicly available in PDF or paper format only, opportunities to use this wealth of information for statistical and computational analysis have been greatly restricted.
