The Pieper-Zulkowski Pressure Ulcer Knowledge Test (PZ-PUKT) was developed and tested for nurses. The 72-item test shows good reliability for assessing pressure ulcer knowledge.

Area of Science:

  • Nursing
  • Medical Education
  • Clinical Assessment

Background:

  • Pressure ulcers represent a significant patient safety concern in healthcare settings.
  • Accurate knowledge of pressure ulcer prevention, risk assessment, staging, and wound description is crucial for nurses.
  • Existing knowledge assessment tools may not reflect current evidence-based practices.

Purpose of the Study:

  • To develop and evaluate the initial reliability of the Pieper-Zulkowski Pressure Ulcer Knowledge Test (PZ-PUKT).
  • To create an updated instrument for assessing nurses' knowledge regarding pressure ulcer prevention, risk, staging, and wound description.

Main Methods:

  • A cross-sectional instrument testing design was employed.
  • Content for the PZ-PUKT was derived from pressure ulcer research and guidelines from the past five years.

  • The 72-item test underwent reliability analysis with two cohorts of registered nurses (N=206 total).

    • Main Results:

    • The 72-item PZ-PUKT demonstrated a Cronbach's alpha of .80 for overall reliability.
    • Subscale reliability coefficients ranged from .56 (prevention/risk) to .67 (staging).
    • Nurses with wound care certification achieved significantly higher scores compared to other groups.

    Conclusions:

    • The PZ-PUKT is a reliable instrument with updated content relevant to pressure ulcer management.
    • Overall test reliability is strong, supporting its use in assessing nursing knowledge.
    • Further testing in diverse clinical settings is recommended to establish a passing cutoff score.
