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
