Talk:CCOW

As far as I understand, CCOW is not indended for 'single sign-on', but for 'application synchronization'. The example would then be clearer if it was along the lines of: 'general practitioner Steph Saunders logs in. His applications subscribe to the context manager. He selects his patient Mary Jane in one of the applications. The other applications pick that up and also tune to that patient.' --Raboof (talk) 11:07, 29 January 2008 (UTC)


 * The article has changed and this concern is likely no longer an issue, but to clarify, CCOW consists of multiple contexts. One would be a 'patient context' that would ensure the same patient is selected in all applications.  Another context is the user context, which ensures that the same user, or care provider, is the one accessing those applications.  The result of maintaining the user context in a CCOW application is Single Sign On (SSO) so that the user of the machine cannot log in to one application as one user, and another application as another user.   I'd guess that patient context improves patient safety, user context improves security and privacy.  Side effect of this is happier users and as such, SSO becomes a big bullet as why an application should be CCOW enabled. 152.16.177.116 (talk) 17:50, 14 January 2010 (UTC)

I think the issue raised is definitely still an issue with the article. While the "single sign on" functionality is frequently used to describe the standard, it is "context switching" that is the chief benefit of the standard. "Single sign on" could be achieved with many password management tools, the real benefit for this standard is that when you have multiple application windows open - including those on different servers and technologies - switching "context" switches all the applications. I believe there are four primary contexts; the patient, the encounter, the account, and the study (?, not sure). For example, when you change patient in application A and you are logged into applications A, B, C, and D, they _all_ switch to the same patient view as if you had provided focus to each window and looked up the patient in that application directly. While this may seem like an odd piece of functionality, integration on the desktop essentially, in health care where disparate applications are often running simultaneously for different systems with different purposes this is a tremendous productivity boost. A common example; a Radiologist has open the image viewer (PACS), Radiology management system (RIS), transcription application, and medical record application. Pulling up a patient in the transcription system lets the PACS application switch to all the images on file for the patient, the RIS shows the patient's appointment history, and the medical record system shows their charts including pathology reports. A great time saver. Lyle (talk) 04:23, 19 April 2011 (UTC)

I think part of the issue with this article is that it refers to the "User" (Mary Jane) when I assume it means the Subject (generally patient). — Preceding unsigned comment added by 63.68.128.2 (talk) 19:53, 7 January 2015 (UTC)
