“If we cannot name it, we cannot control it, finance it, teach it, research it or put it into public policy.”
(When nurses can describe what they do in terms that the public and others can understand, they begin measuring it, evaluating it, and validating its impact on the nation’s health, research, and public policy. )
–By Lang, N. 1993
The focus of traditional clinical nurse is taking care of patients. Therefore, historically, computers in nursing were seen as to manage patient care data, to analysis data into information in order to monitor quality of care, and eventually help evaluate patient outcomes. With the commonly used of networks, clinicians are now using computers for communications via internet, obtain and exchange information and resources, and interact within multidiscipline and as well as interacting with patients and patient family members. In the meantime, nurses found themselves in the mid of using computer systems for patient care planning, system managing, policy making, nursing education, and nursing researches.

What is Six Sigma?
- A comprehensive and flexible system for achieving, sustaining and maximizing business success.
- is uniquely driven by close understanding of customer needs, disciplined use of facts, data, and statistical analysis, and diligent attention to managing, improving, and reinventing business processes.
- The goal of Six Sigma is to eliminate all defects
- Six Sigma implies a goal of no more than 3.4 defects per 1 million opportunities

Usability studies can be used to support IT in a number of ways. Which of the following are reasons to complete these studies in a health care setting? –assesses the adequacy of a design or redesign early in the systems life cycle, helps determine or clarify users’ requirements determination
Usability: the ease with which people can use an interface to achieve a particular goal. issue of human performance during computer interactions for specific tasks within a particular context. which deals with specific issues of human performance during computer interactions for specific tasks within a particular context. usability issues address the efficiency and effectiveness of an application. For example:
- the ease of learning an application
- the ease of using an application
- satisfaction with using
- efficiency of use
- error tolerance
- fit of the system to the task
- the speed of task completion and errors that occurred during application use when determining which system or application would be best used on a nursing unit.
- Heuristic Evaluation = discount usability evaluation method: to detect problems early in the design process, when they can be most easily and economically corrected.
- Formal usability test: use either experimental or observational studies of actual users using the interface to accomplish real-world tasks.
Ergonomics: the design and implementation of equipment, tools, and machines related to human safety, comfort, and convenience. commonly refers to attributes of physical equipment or to principles of arrangement of equipment in the work environment.

A systems development life cycle (SDLC) is a frame work for describing the phases of developing information systems.
- nursing informatics is the nursing specialty practice that “integrates nursing science, computer science, and information science to manage and communicate data, information, knowledge, and wisdom in nursing practice” (ANA 2008).
- the standards of nursing informatics practice:
- problem identification
- outcomes identification
- implementation (coordination of activities, teaching/ promotion/ education, consultation)
- The SDLC contains:
- initiation, analysis, design, implementation, and continuous improvement of support
- The nurse informatician working on tasks in the design phase of the Systems Development Life Cycle uses the findings of the –Analysis phase as a blue print– the findings and plans developed in the analysis phase provide the guide for the design phase of the SDLC
The informatics specialist is in a unique position to promote the integration of consumer informatics into the mainstream of health care delivery. true statement about the nurse informatics clinical specialist? –the nurse informatics clinical specialist can be part of the life cycle process. — with the increase in health care technology, the incorporation of a nurse informatics specialist can help to provide patients and nurses the tools to understand the use of technology and promote the widespread adoption of consumer informatics.

When displaying patient data for clinical decision making, which type of display tends to slow cognitive processing of the data? — multiple displays on one screen (distracting and slow cognitive processing of data. in most cases, multiple modes of presentation of data provide the best information)
The effective display or patient data for clinical decision making requires that information be rapidly available with minimal cognitive effort. The decision tree is a common presentation with potential options, consequences, and expected outcomes.
Graphs: line graphs, column graphs, and bar charts (compare variables), pie charts and area charts (illustrate the percentage composition of an entity)
Line graph: used to show data over a period of time. is considered the best type of chart for displaying data over time.
Table: use labeled columns and rows to present statistical or alphabetical data in an organized way. although technically not visual aids, they provide a different way of grouping and presenting analyzed data that an analyst wants to communicate to proposal readers.
Pictorial displays: visual indicators, such as colors, may be used to highlight information, such as abnormal lab results, and pictorial displays can be effective.
