Interfaces require cooperation by both vendor parties. Some companies are more complex to deal with than others. Interfaces are time-consuming to design, implement, and support. Interfaces require a one-time charge, which is based on the hours of technical effort required to achieve the interface. Software version upgrades can require interface redesign.
Version control can be a problem.
B. Patient information exists in different places, requiring interaction with several devices or systems. Images for the same patient may be stored in different systems leading to some confusion as to where an interested party needs to search in order to view the entire patient radiology record, which includes images, results, and order status information. The user may need to query multiple systems in order to find the information needed about the patient. In that case, it must be quite clear to the user that information is stored in multiple locations. C. Paper-based information is not well addressed.
