Emerging Infections Programs (EIP)
EIP Web Service
Background Enhanced EIP Web Service EIP Web Service Architecture Next Steps
What is EIP?
The Emerging Infections Programs (EIP) is a population-based network covering 15% of the population and consists of projects to improve patient outcomes through evaluation and improvement of emerging infection prevention and control methods.
Over 40 projects and around 20 special studies
A collaboration of CDC, state health departments, universities, hospitals, and other federal agencies.
Over 500 publications
EIP IT
Mix of information system types – study databases, case information management systems, site systems
Systems used for projects can vary by site Multiple transport methods in use Project protocols can change yearly
Adopted IT Strategy in 2012
Problem
CDC-developed case management system Two installations – CDC and at each site Current process was cumbersome and open
to errors Export to file from one system and upload
to other
Existing alternatives
SAMS PHINMS SFTP
Current EIP Web Service
Existing EIP Web Service release 1.5- Supports only a single EIP Program- Designed as proof of concept- Minimally extensible architecture
Enhanced Web Service aligns with key strategic EIP IT goals:- Improve and modernize current EIP technology- Adapt and transform PH information is and will be exchanged, expanding use of EHR data, utilizing other or novel sources
EIP IT Goals align with CDC surveillance strategy goal:…accelerating the utilization of emerging tools and approaches to improve the interoperability, availability, quality and/or timeliness of surveillance data
EIP Web Service v2.0
Is reusable by other C/I/O’s As CDC Shared Services, with appropriate resources to
NCEZID for additional support personnel and expansion to more scalable server configurations
Changed the framework and service to support a second EIP program
Provides support for new data interfaces through Requires only configuration and minor development
specific for new data
EIP Web Service – Data Flow
Data transport protocol designed for use between state surveillance information systems and CDC
State surveillance information systems invoke EIP Web Services (in CDC DMZ) to fulfill the application requests to transfer non-PII data to CDC
EIP Web Services logs and stores received data in EIP Repository is shared with EIP CDC programs.

EIP Web Service - System Architecture
Modular Approach
Adopted SOA – Service Oriented Architecture
Every function / feature is a service that can be hosted in the CDC DMZ
All the services can be shared and reused with minimal effort
EIP Services can be shared with other programs or other CIOs can hosted
Custom Security
OCISO approved custom IP based security Machine to machine communication Communication using HTTPS only. (HTTPS ports only) Passwords are encrypted; no clear password text IP based security; IP extracted on the fly from SOAP
requests
Why not SAMS authentication? No API available for SAMS SAMS does not support SOAP SAMS Identity proofing is limited to humans/users, not
for the machines
Multiple IP Support
ITSO does not support implementing firewall rules at the application level
All standard IPs are enabled by default Supports range of IP addresses from States Supports limited and logical firewall rules Unauthorized IPs blocked by EIP WS and
requests logged without processing Supports both IPV4 and IPV6 addresses
Extensible
EIP WS are SOAP-based services Expandable to RESTful services Easily extensible for two-way data
communication between states and CDC Expandable to transfer data types XML,
JSON, TEST, CSV, Excel and serializable binary data streams
Next Steps
ATO received
April 17 √
Testing with partners
May - June 2015
Replace existing EIP WS
July 2015
2nd EIP project implemented January 2016
Available for other CDC Programs

What is REDCap?
A secure, HIPAA-compliant, web-based application designed specifically to support data capture for research studies
• Research data collection forms and surveys
• Coordinate multi-site, collaborative studies through SAMS (Secure Access Management System)
• Diverse research applications
TMTM
REDCap Features
• WYSIWYG instrument design tool• Single event or multiple event
(longitudinal) surveys• Data export to common statistical
packages• Data import from Excel • Role-based user rights
management
TMTM
REDCap Features
• Interactive audit trail• Customizable reporting and analytics• Electronic delivery of surveys to
participants• Field validation, branching logic,
calculated fields• Data access groups (DAGS) • Reusable online question repository
TMTM
REDCap Features• Native mobile application for Android Devices
