    This study developed a method to measure nursing information processing. Experts, unlike novices, focused on vital signs, pain, and neurological status to assess patient conditions.

    Area of Science:

    • Nursing Science
    • Cognitive Psychology
    • Information Science

    Background:

    • Effective patient assessment relies on nurses' ability to process complex information.
    • Understanding cognitive differences between expert and novice nurses is crucial for improving patient care and education.

    Purpose of the Study:

    • To develop and demonstrate a methodology for measuring the information content and processing strategies used by nurses.
    • To identify key features of information processing that differentiate expert nurses from novices in patient condition assessment.
    • To suggest specific information processing characteristics that aid nurses in determining patient status.

    Main Methods:

    • A simulated client problem involving 59 data elements was presented to 23 expert and 37 novice associate degree nurses.

  • Latent Partition Analysis (LPA) was used to identify common categorization of 12 patient problem categories derived from data element sorting.
  • Statistical comparisons included t-tests and rank order correlations to analyze differences in data element selection and category emphasis between expert and novice groups.
  • Nine judges evaluated the 12 identified protocols for conformity to experienced nursing practice.

    • Main Results:

    • Twelve distinct categories of patient problems were identified through data element sorting and LPA.
    • Experts requested more data elements and placed greater emphasis on current vital signs, pain assessment, and neurological checks compared to novices.
    • Significant differences were observed in the mean number of data elements requested and the emphasis placed on specific LPA categories between the two groups.

    Conclusions:

    • The study successfully demonstrated a methodology for quantifying nursing information processing and content.
    • Expert nurses exhibit distinct information processing patterns, prioritizing critical physiological and neurological data for patient assessment.
    • Findings provide insights into cognitive strategies employed by nurses and can inform nursing education and clinical practice guidelines.
