Hosted TouchChart Scan
This article will assume an MSO environment with each practice represented by its own TouchWorks organization and connected to the datacenter over the Internet.
When implementing scan, the MSO needs to decide whether to install the Scan client on local PCs or run the application via the Citrix server. There are pros and cons to both.
First, a benefit of installing the application locally is the reduced cost of not needing Citrix. On a busy network, it is strongly advised that the batch process be deployed to queue the scanned images and transmit them off hours or at a time when users are less likely to be impacted by the increased bandwidth usage. In most cases, an MSO practice does not have WAN or LAN connectivity to the servers. Because of this, a local installation of Touch Chart requires a VPN connection.
The negative factors of installing locally are that the speed and efficiency because of the bandwidth needed to run the application.
In terms of running Scan through a Citrix environment, productivity and speed are typically greater because the communication between the client and the server occurs over a LAN. Security can also be better enforced through a Citrix environment. The batch process is also utilized in the Citrix model.
There are additional expenses associated with selecting the Citrix model, (A nominal fee from Allscripts for the remote scan setup, and the associated Citrix costs. The increased security, ease of administration and relative simplicity of upgrading the Touch Chart client make this an attractive option.
