WISHIN Pulse employs a federated, hybrid data model – so participant data is not stored centrally or co-mingled with the data of other participants.  Using a record locator service, WISHIN Pulse knows which organizations to look to in order to get a patient’s health information – so very little health information (if any) is stored in the health information exchange (HIE).

WISHIN Pulse participants have the following options for how their data is stored: 

1.    WISHIN/Medicity hosts the participant organization’s data stage

  •  Data is not co-mingled with the data from other participants
  •  Highly available
  •  SLAs in place with Medicity to ensure performance
  •  No separate “hosting” fees (included in WISHIN subscription fees)
  •  Can be “turned off” at the request of the participant (covered in the participation agreement)
  •  Participants can do site visits of the data center if needed       

2.    The participant organization hosts its own data stage

  • Must be “highly available” in order to ensure timely return of query results to the exchange; this applies to hardware, software and network.
  • Participant pays for all hardware, software, and network components
  • Can be “turned off” at the request of the participant

Hosting Your Own Data Stage

If your organization wants to host your own data stage, you must:

1.    Acquire the following edge servers and host them in your own Tier 4 data center (these are minimum requirements): 

  • MediTrust Servers – 2 Servers with 2 CPUs, 16 GB RAM.  Storage should be SAN1 attached. 
  • Data Stage Servers – 2 Servers, Clustered, with 4 CPUs, 32 GB RAM.  Storage should be SAN1 Attached                      
    1
    Total storage required on the SAN could vary from 1 TB to much higher depending on the volume of data you would be hosting.

2.    Commit to the following:

  • Co-locate servers in a professionally managed Tier 4 data center
  • Provision the latest Wintel, clustered infrastructure
  • Coordinate patch management with HIE
  • Maintain a secure, fault-tolerant network
  • Provide DS3 or better connectivity to HIE
  • Manage backups and database maintenance
  • Manage disaster recovery & BCP plans
  • Monitor and support the infrastructure
  • Host the MediTrust & Data Stage software packages on the servers noted above
  • Participate and disclose security audit findings
