Abstract: Techniques are described for providing information about a current state that is modeled with multiple state attributes. In some situations, the providing includes receiving from first and second sources indications of an ability to supply values for, respectively, an indicated one of the state attributes and another of the state attributes. In such situations, the providing also includes, in response to receiving a request from a first client for a value of the indicated one attribute, determining that the first source is available to supply the value, obtaining the value from the first source, and supplying a value obtained from the first source to the first client.

Abstract: Techniques are described providing mediated information about a current state that is modeled with multiple state attributes. In some situations, the providing includes receiving from a first source an indication of a first value for an indicated one of the state attributes of the modeled current state, receiving from a second source an indication of a second value for the indicated state attribute, and, after an indication from a client for a value for the indicated state attribute, sending to the client a mediated value for the indicated state attribute that is produced by mediating between available values for the indicated state attribute including at least the first and second values.

Abstract: A system that can collect data, directly from a client and use this data both to diagnose and to establish the severity of a client's condition. The system can also use this data to look-up one or more appropriate treatments according to treatment guidelines stored in its memory. It then uses this information to monitor if the treatment decisions made by the treating clinician or other medical provider is consistent with the stored treatment guidelines. The system can suggest treatments to the medical provider, inform the provider if the provider chooses a treatment or treatments that do not follow the treatment guidelines, require the provider to actively over-ride the treatment guidelines or require the provider to obtain agreement to over-ride from a supervisor. Additionally, the system can store information on treatments that do not follow the treatment guidelines for ongoing review of provider performance by provider supervisors.
