backward chaining production rules
...starts with a list of goals (or a hypothesis) and works backwards from the consequent to the antecedent to see if there is data available that will support any of these consequents.[2] An inference engine using backward chaining would search the inference rules until it finds one which has a consequent (Then clause) that matches a desired goal. If the antecedent (If clause) of that rule is not known to be true, then it is added to the list of goals (in order for one's goal to be confirmed one must also provide data that confirms this new rule).

national disease surveillance database paramaters
Quality control and error checking are crucial for users to have faith in the accuracy and comprehensiveness of the data. Encryption of data refers to privacy and data protection before the transmission of the information. Standards for data transmission address the need for developers of electronic health records and clinical databases to adopt a single standard for communicating and transmitting the information. Standards for data definitions refer to the adoption of standards for clinical terminology and for schemas used to store clinical information in databases.
Relative risk
RR is a ratio of two risks - it is the ratio of the event rate of the outcome in the experimental group (EER - experimental event rate) to the event rate in the control group (CER - control event rate). RR=EER/CER In statistics and mathematical epidemiology, relative risk (RR) is the risk of an event (or of developing a disease) related to exposure. Relative risk is a ratio of the probability of the event occurring in the exposed group versus a non-exposed group.

Switches and routers
Switches provide a point of connection among devices on a network. They vary in the degree of functionality by which they manage data traffic that passes through them (hub-->bridge-->repeater--> router. The hub is the simplest and least expensive device providing passive transmission or receipt of data from one computer at a time. A bridge performs the functions of a hub and in addition can limit the sending of data to specific known hosts thereby providing a level of security. A repeater is a device that receives a signal and retransmits it at a higher level, simply extending a network. A network router is the most technically sophisticated switch and is capable of examining the contents of data passing through it, identifying the sender and receiver, and providing a higher level of security using the Internet protocol (IP) address. AMIA content outline 3.1.3 Networks

MLM and Arden
The Arden Syntax for Medical Logic Systems encodes medical knowledge in knowledge base form as Medical Logic Modules (MLMs). An MLM is a hybrid between a production rule (i.e. an "if-then" rule) and a procedural formalism. Each MLM is invoked as if it were a single-step "if-then" rule, but then it executes serially as a sequence of instructions, including queries, calculations, logic statements and write statements. Arden was developed for embedding MLMs into proprietary clinical information systems. It was designed to support clinical decision making in particular: an individual MLM should contain sufficient logic to make a single medical decision.
Blue Button
The Blue Button is a symbol for patients to view online and download their own personal health records. Several Federal agencies, including the Departments of Defense, Health and Human Services, and Veterans Affairs, implemented this capability for their beneficiaries. Blue Button has pledges of support from numerous health plans and some vendors of personal health record vendors across the US. Data from Blue Button-enabled sites can be used to create portable medical histories that facilitate dialog among health care providers, caregivers, and other trusted individuals or entities. Currently widespread Blue Button usage supports downloading human-readable data in ASCII.[3] As a step towards enabling the exchange of parseable data, on 16 January 2013 the Office of the National Coordinator for Health IT recently announced [1], an implementation guide for data holders and developers to enable automated data exchange among Blue Button+ compliant applications using structured data formats. Blue Button+ is designed to enhance the ways consumers get and share their health information in human-readable and machine-readable formats; and to enable the use of this information in third-party applications.

Put your people first 4. Act with integrity 5. Be a great communicator 6. Be a great listener 7. Be a problem solver 8. Lead through experience and competence, not through title or position
What is the principle difference between an ontology and a controlled vocabulary (terminology)?
The fundamental difference between an ontology and a controlled vocabulary is the level of abstraction and relationships among concepts. A formal ontology is a controlled vocabulary expressed in an ontology representation language. This language has a grammar for using vocabulary terms to express something meaningful within a specified domain of interest. The grammar contains formal constraints (e.g., specifies what it means to be a well-formed statement, assertion, query, etc.) on how terms in the ontology's controlled vocabulary can be used together. Controlled vocabulary used in making ontology not only to reduce the duplication of effort involved in building an ontology from scratch by using the existing vocabulary, but also to establish a mechanism for allowing differing vocabularies to be mapped onto the ontology.

Change - Motivation
defined as the process that initiates, guides and maintains goal-oriented behaviors. According to Maslow, people are motivated by unsatisfied needs. At lower levels of Maslow's hierarchy of needs, such as physiological needs, money is a motivator; however it tends to have a motivating effect on staff that lasts only for a short period (in accordance with Herzberg's two-factor model of motivation). At higher levels of the hierarchy, praise, respect, recognition, empowerment and a sense of belonging are far more powerful motivators than money, as both Abraham Maslow's theory of motivation and Douglas McGregor's theory X and theory Y (pertaining to the theory of leadership) demonstrate.

heuristic modeling and expert systems
• these simulate human expertise and reasoning processes • need these because in some settings you don't have enough data to use an probabilistic approach •these systems can explain their conclusions and be understandable to humans •examples -rule-based systems - individual logical statements in the form of production rules; rules determine if they should fire based on interference engine; 1975 MYCIN system (certainty factors); rules-based command executed and bottom-up (forword chaining) or backward chaining -frames or attributes; internist-1, QMR
probabilistic and data-driven classification or prediction
• updating probabilities based on evidence - Bayes theorem • decision analysis - formal methodology a statistical decision theory, Howard Raiffa; user decision tree circles equal chance squares equal decision nodes, used primarily for policy analysis and the formulation of guidelines and rules, allows you to lay out the sequence of decisions of possible outcomes eight steps of the decision-maker can focus on critical variables such as the probability of various branches the cost or risk of treatment; uses a fullback analysis • Bayesian belief networks
CDS methodology information retrieval
• used to find information, answer questions • can be user initiated such as searching MEDLINE or automated/semi automated such as infobutton • can be taxonomy/ontology based (controlled vocabulary, consisting of terms by which the concept has been pre-indexed) or text based --- more complicated expressions using term indexed resources can be done using Boolean expressions comprise the logical combinations of terms; hierarchical - so the higher levels room can be used to conotate the desire to explode the subtree into lower terms
