The software environment is also adaptable to a broad range of behavior modification and self help applications including applications such as monitoring current wellness state. 2. Description of the Related Art Healthcare costs continue to escalate at a steep rate. Cost increases have occurred in all areas, including insurance premiums, medical equipment, medicines and costs for visits to doctors. A great deal of energy has gone into finding ways to reduce healthcare costs, from government control of aspects of health care to insurance company managed care plans to control patient utilization of the healthcare system and provider actions. Systems have been created to institute a process that automatically generates a database of candidate at risk patients. The process of identifying the patients can be fully automated. Along these lines, insurance records in electronic medium can be processed using the software that produces a database of at risk patients. This is one source of candidate patients for the present invention. Patients could also be selected manually by health care workers. Some known systems include a suite of knowledge sets for assessing and managing compliance with medical protocols. The knowledge sets can specify cause and effect behavior that relates patient beliefs and behavior to compliance management issues. Such knowledge sets can serve as a source of knowledge utilized by the present invention as described below in greater detail. SUMMARY OF THE INVENTION The present invention provides protocols and environment for applying knowledge to health care risk management. The protocols and environment identify a sequence of actions and knowledge sets based on patient information that may be involved in health care risk management. The protocols and environment for identified at risk patients can include assessing compliance risk, establishing compliance goals, identifying and applying required interventions, and collecting and annotating medical information relevant to the compliance management process. The environment provides a suite of software tools that seamlessly couple the protocols and knowledge in a health care provider intuitive fashion. The present invention includes a computer software environment and systems architecture. The computer software includes a computer readable medium and computer program instructions recorded on the computer readable medium and executable by a processor for performing the steps of the method of the present invention. The system architecture design enables reconfiguration to many client-server implementations to support different business models. For example, the present invention can support a standalone platform, a local area network, and/or world wide web implementations. The architecture may be based on Java technology that ensures portability and platform independence. The architecture can leverage the Java Enterprise technology, which provides for flexibility and incorporation of enterprise support services such as transaction management and security capabilities. Furthermore, the architecture is constructed using object technology that mirrors the problem domain taxonomy. Still other objects and advantages of the present invention will become readily apparent by those skilled in the art from a review of the following detailed description. The detailed description shows and describes preferred embodiments of the present invention, simply by way of illustration of the best mode contemplated of carrying out the present invention. As will be realized, the present invention is capable of other and different embodiments and its several details are capable of modifications in various obvious respects, without departing from the invention. Accordingly, the drawings and description are illustrative in nature and not restrictive.

DESCRIPTION OF THE PREFERRED EMBODIMENT(S) It has been determined that a small percentage of patients consume a significant portion of the health care plan's resources. This is particularly true in managed health care plans. Consequently, in an attempt to contain health care costs, it is desirable to address the issue of patients that consume a significant share of medical resources. This represents just another means of managing health care costs. The present invention addresses this problem by providing a way to identify these patients in the overall population of a healthcare plan and then manage their utilization of medical resources to control costs and more effectively deliver care to both the high utilization patients as well as all patients in the system. Like many other areas of activity, healthcare can benefit from automated/semi- automated processes such as decision aids for patient case management and data bases that collect patient specific performance for process improvement techniques that have been so useful in business today. In addition, data mining techniques can be utilized in health care to discover relationships among data that it would otherwise be impossible or impractical to obtain manually. These new relationships allow for process improvement, which in turn produces new relationships. Thus, the present invention provides a foundation and automated method for a learning organization. The present invention provides a protocol and environment, or software, to manage risk in healthcare and to assist in compliance management. Patients can enter the process through various mechanisms. In particular, identification of at risk patients can take place automatically through processing insurance records in electronic form. Among the aspects of the records that are analyzed are claims data, prescription data, referral data, and a review of overall utilization. Patients can also enter through referrals. Steps are carried out to reduce the cost of caring for these patients yet maintain an adequate level of care. Once these patients are identified, each patient is interviewed for compliance risk assessment. Assessing at risk patients can include posing a series of questions to the patients. The questions can evaluate a number of aspects of the patient's attitudes, including their beliefs and behaviors regarding their health, attitudes toward their health, managing their health and the healthcare system and/or any other topic. Examples of questions can include questions on the SF-12 health survey. More information on the SF-12 can be found at the following internet site http://qmetric.com/innohome/insfl2.shtml, the entire contents of which and all linked sites are hereby incorporated by reference. Analysis of the patients' answers to the questions can reveal patients' relative risk with respect to compliance with a treatment regimen and predict patient compliance with the regimen. In some cases, some of the at risk patients may be eliminated from further consideration by the system if their score indicates that they are not really at risk, or their beliefs indicate non- compliance. A nurse, physician or other person may pose the questions to the patients. In such an embodiment, the questions could be posed in person or over the telephone. The questioner could pose questions from a printed list of questions. On the other hand, the questions may be generated by a computer system and displayed on a graphical user interface (GUI) where the questioner can read them. The questioner can write down the answers or enter them into the GUI and the answers are stored in a database. According to another embodiment, the internet is utilized to conduct patient compliance risk assessment. A patient would access a web site. The web site would prompt the patient for a password or some other identifying number that will permit a server to identify the patient and access the patient's profile. After identifying a patient, the questions would be transmitted to the patient via the internet. Subsequently, the patient's answers would be transmitted over the internet to a compliance risk assessment system. Regardless of how the questions are posed to the patients, the questions are tightly coupled to the specific patient circumstances, including disease and health status. Patient responses are stored in a patient profile data set. Each patient has a patient profile, which contains a dynamic representation of the patient's current state. Patient responses may invite a new series of questions - the questions adapt to the responses. The adaptation process may be continued throughout the questioning. Along these lines, as answers are received to questions, a decision tree may be utilized to guide the questioning. The questioning may be stopped by the questioner or may be automatically terminated by a computer system. Termination of the questioning may take place upon reaching a certain point or may be terminated by the questioner, the patient or the system at an arbitrary point. Additionally, numerical values may be attached to answers to any or all of the questions. Assigning values to the answers can permit a more objective representation of the patient's compliance risk status to be developed. Also, quantifying patient responses can lead to more standardized care at least in part by replacing judgement calls by questioners with more standardized operations. If the assessment process leads to identifying a patient as at risk, a provider, whether a nurse, physician, nurse practitioner, physician's assistant or other person, may be assigned to a patient to develop, implement, and/or ensure compliance with a course of action. The adaptive decision tree can be employed to guide the caregiver to an appropriate course of action. In fact, the course of action may be continuously modified as patient attitudes and behavior changes, as reflected by continued interaction with the system. Figure 3 illustrates this process. As can be seen in Fig. 3, the results of the patient interviews performed in Risk Assessment provide the initial data used to form the plan to manage patient compliance. Patient interactions are recorded. These interactions can include facts and judgements as well as the patient's health status. The interaction and record thereof can go into developing the patient profile. Furthermore, the patient profile is used by the plan to adapt the compliance management process. Fig. 2 illustrates aspects of this portion of the present invention. During compliance management, interaction with the patient typically continues. Along these lines, assessment may continue of patient beliefs and behavior, particularly behavior with respect to carrying out the course of action, or care plan, developed for the patient. Along these lines, questions may be posed to the patient regarding particular issues that exist in their care plan. If necessary, the care plan may be altered through time to help ensure patient compliance and/or to adapt to changing circumstances, such as changing health status. Also if necessary, a health care worker may intervene to help ensure compliance. Fig. 4 illustrates the process of knowledge base mining. The contents of the patient profile database are the resource used in knowledge mining techniques. The techniques extract additional risk assessment and compliance management knowledge that can be subsequently used in the process. Fig. 5 illustrates various embodiments of a system according to the present invention. Fig. 6 illustrates in greater detail one, two, and three tier business models. As illustrated in Fig. 6, software according to the present invention may be built using functional building blocks, including user interface classes, business logic classes, data set classes, data provider classes, data resolver classes, class stubs, and the database. This functional decomposition allows for an architecture that can replicate and distribute the building blocks as necessary to seamlessly support one-, two-, and three tier business models as shown in Fig. 6.
