Page History

The organisations currently using PAT CAT have expressed interest in sharing aggregated data across their catchment boundaries. This functionality The PAT CAT Network has been created to provide this functionality and will provide the ability will be particularly useful to compare indicators across organisation and other multiple organisation catchments and/or state borders.

The PAT CAT Network allows information to be shared through the use of “Channels”. A channel defines a set of filters and graphs for which an organisation is willing to share data with another. An organisation “subscribes” to a channel to participate. Only aggregated data is shared. The data becomes available by “connecting’ to a channel and then viewing the data through the normal PAT CAT interface along with the organisations own data for comparison. When connected to a channel, the predefined filters replace the usual PAT CAT filter panel and the graphs for which shared data is available are flagged with a * on their tab. A filter is selected to recalculate the data.

To enable data sharing without PEN CS becoming a data custodian we have expanded the PCS Network to handle the PAT CAT Network data travel. The PCS Network is currently used to provide the prompts data travel from PHN/organisation to practice. It does not store any data from the individual organisations using PAT CAT, but rather stores the details of the direct data connections, i.e. who sends what to who.

Organisations are required to register to use the PAT CAT Network through the PCS Network before they can share and view data. Only Super Admins can register to the PAT CAT Network. 

...

This is done the first time the organisation clicks on the PAT CAT Network icon and is managed through the PCS Network.

The PAT CAT Network functionality is accessed through the new PAT CAT Network icon:

...

Clicking the PAT CAT Network icon will open up the PAT CAT Network window. From this window you can create and join channels, see and respond to notifications and manage your subscribed and created channels. More detail is provided below.

Channels

Information will be shared through 'Channels' that have to be created by the PAT CAT Super User within the respective organisations. These channels can be public or private. The organisation who created the channel will be its owner and will participate in all filters and graphs.

• Private Channel
  • Other registered participants can only join upon accepting the invitation from the channel creator.
  • Private channels will not be available for other organisations to request to join the channel
• Public Channel:
  • Other registered participants can only join after either accepting the invitation from the channel creator or approval of its join request.
  • Join request can be made by other organisations wanting to join the channel.
  • Channel owner must approve the join requests.
  • Public channels will be listed, so that other organisations can view their details

Channels contain the following information:

• Name
• Channel type (Public/Private)
• Graphs
• Filters

Channel creating will be done real time. This means that the moment the user clicks and assuming that all validations are passed, then the data will be in the PCS Network and will be instantly available for viewing.

Channel Invitation

Only organisations who are registered as participants in the PAT CAT network will receive invitations to a channel. Only the owner/creator of a channel can send an invite to a channel. Invites will be shown in the invite list. An organisation can send a join request to the owner/creator of that public channel. Once the join request is accepted by the owner the channel will become available.

To invite an organisation to your channel, click on the '+ Invite' button:

Selecting a Connected Channel Filter

Pre-Requisites:

• A organisation must be registered
• Be connected to a Channel
• Cached data is available at the source organisation

Selecting a channel filter will make PATCAT apply the selected filter to the organisations current data. This will also collect data from other organisation that also participates in the same filter and graph – provided the cache data has been generated by the source organisations

The following areas will display the data from other organisations:

• Benchmark report
  • The data will be appended to the current grid
  • The data will also be grouped, just like the current grouping functionality
• CSV and PDF download (Graph specific)
  • The data will be appended to the results
  • The data will also be grouped, just like the current grouping functionality

Channel Delete

• organisation must be owner of the Channel

In the My Channels listing, each channel will have a delete functionality that deletes the channel in the PCS Network in real-time. Local data will be updated to reflect the deletion.

PATCAT Data Caching

PATCAT windows service will be extended to provide functionality to cache aggregate data for PATCAT Network

During a given time, the data caching will go through the organisations participating filters and graphs in his/her local database. A collection of filter-graph combinations will be created. For each one, the data result will be saved against it.

This data is used to share when another organisation that participates in the same filter-graph requests for the data

Features:

• PCS Network does not store Patient Data
• PCS Network will only store Channel related data
• Data sharing is done directly between PAT CATs
• The aggregated value and percentage part of the data is encrypted
• Data transmission only through SSL
• Data sharing is only within the scope of the connected channel
• Organisations can only look at other PAT CAT data for the selected month
• Consent / Opt-In process for organisation is captured via the PCS Network
• Only PAT CAT Super Users can register to the PAT CAT Network. 
• Only PAT CAT Super Users can create channels
