NIS for decision support

Decision-Support Systems developed to assist nursing http://www.mieur.nl/mihandbook/r_3_3/panels/panel_14_01.htm (spaces indicate underscore lines "...book/r_3_3/panel_14...")

• System Analysis
  • Describe and identify nursing practice.
    • Establish the practice model/conceptual framework
    • Separate the project components
    • Define components and their purposes
    • Define terms and data
  • Decide purpose of data
    • Determine system linkages
    • Determine data needs from other systems
    • Decide data requirements for decisions
• Plan the design
  • Define the design
    • Decide design requirements
    • Clarify functional specifications
    • Determine program specifications
  • Prioritize the work
    • Estimate the development work load
    • Prioritize nursing needs
  • Assign resources
  • Allocate time and goals [Top]

Benefits include compliance to practice standards, tracking and monitoring quality, improved communication, and mechanisms to further the "science of nursing"

• Define database
  • Establish rules for determining data
    • Omit unnecessary information (experienced nurse is basis)
      • Use helps for explanations and Instructions
      • Incorporate standards of practice.
      • Omit cross-system data redundancy
    • Establish data quantity
      • Data differences between paper and electronic system
      • Impact on documentation requirements
      • Justify additional data requirements
      • Restrict to necessary items
  • Identify data elements
    • Identify sources
      • Use of manual and preexisting forms and standards
      • Use of nursing reference materials
    • Set text limits
    • Define each item/statement independently
    • Limit use of free text
    • Match data types between sources
  • User review of database
  • Determine data coding methods
    • Method and format for data storage
    • Method and format of data retrieval
    • Use of data by others
    • Space requirements
    • Flexibility needs
    • Choice of taxonomy [Top]

• Data manipulations
  • Data entry methods
    • Screen development
    • Consider ergonomics: movement, typing, data volume, consistency
    • Establish helps: navigation, information, instruction
    • Keep response times under 2 seconds
    • Establish methods for error checking
    • Determine data editing: errors, data change, inactive data
    • Establish security measures: audit trail, passwords, access
    • Develop methods to generate reports
  • Establish program design
    • Decide data format
    • Build in flexibility
    • Consider maintenance and revision needs. [Top]
