PHLIP – Who and What

Actors and Use Cases

  • Electronic Lab Surveillance Message (ELSM)
          • Public Health Lab (PHL) to Centers for Disease Control and Prevention (CDC) WHO Global Influenza Surveillance Network
  • Electronic Test Order and Result (ETOR)
          • PHL to CDC Lab and back
          • PHL to PHL and back
  • Route-not-Read (RnR) hubs

PHLIP is supported by cooperative agreement #CCU303019 from the Centers for Disease Control and Prevention (CDC).

PHLIP – ELSM: Current Activities

Data exchange requirements developed and released

PHLIP Workgroup (PHLs and CDC) collaboratively build knowledge and improve process

Technical Assistance Team (TAT)

supports implementation virtually

and on site since March 2010

Technical Implementation

elr initiative vision
ELR initiative – Vision

Provide assistance to Public Health Labs and Public Health Agencies

Promote interoperability

Promote adherence of messaging and data standards amongst data exchange partners including LOINC, SNOMED and HL7 messages

Enable state public health labs (SPHLs) to exchange laboratory data with public health agencies (PHAs) building the data exchange infrastructure for other use cases

One-on-one tailored technical assistance, while developing a common baseline/framework and reusable components.

Collaborate with each other as well as other national efforts

elr initiative programs
ELR initiative – Programs

2010-2012

LTIAPH: Laboratory Technical Implementation Assistance for Public Health

ARRA HITECH grant for 10 ELC grantees plus 2 guests

Data flow from PHL to PHA

Consultative (not prescriptive/enforcer) role

ELC grantee list: Arizona, Florida, Houston, Iowa, Massachusetts, Michigan, New York State, Philadelphia, Rhode Island, and Virginia

LTIAPH is supported by Cooperative Agreement Number 1U50HK000105 from Centers for Disease Control and Prevention (CDC).

ELR initiative – Programs

2011 - current

ELRTA: Electronic Lab Reporting Technical Assistance

CDC sponsored assistance to PHA to connect to PHLs AND

Commercial labs – and provide help with v2.3.1 connections, if needed

Application process managed through CDC

Targeted Technical Assistance by APHL informatics team

ELRTA is supported by cooperative agreement #CCU303019 from the Centers for Disease Control and Prevention (CDC).

elr initiative program approach
ELR initiative - Program Approach

Balance level-of-effort between providing and developing a common framework and re-useable components and one-on-one assistance by building Menu of Services

Leverage “webinar” concept to plan milestones and share the knowledge with broader audience

Conduct Current State Assessment

Collaborate with other national efforts (ELR Taskforce, RCMT update, LabMCoP, S&I Framework lab related initiatives and PH reporting)

vocabulary messaging guidance
Vocabulary & Messaging Guidance

Formed Vocabulary Core Work Group

Developed “ELR 251 Constrained Profile”

Disease/agent prioritization (Tier-1, Tier-2, etc)

Pilot group : Chlamydia, Gonorrhea, Salmonellosis, Hep C, Pertussis and HIV

Map vocabulary for ‘Pilot Group’

Tests and Resulted Tests: LOINC

Test Results : SNOMED-CT

Specimen : SNOMED-CT

Leverage RCMT for Tier-1 and Tier-2

Technical Implementation

Review existing data flows / architecture

Create prototype tooling

Conversion to ELR 251

Up convert to ELR 2 5 1 from 2. 3.1, 2.3.z and other variations

Down convert from ELR 2.5.1 to 2.3.1
