Nursing Informatics Terminology Self Study: usability, ergonomics, change theory

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.

Nursing Informatics Terminology Self Study: Systems Development Life Cycle, Needs Assessment, Analysis Phase, Gap Analysis, Risk Analysis, Risk Management

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:
    • assessment
    • problem identification
    • outcomes identification
    • planning
    • implementation (coordination of activities, teaching/ promotion/ education, consultation)
    • evaluation
  • 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.
