A new Yarkony-Kirk scale for pressure ulcers shows excellent reliability, outperforming the Shea classification. This grading system offers a more complete description of ulcer healing and prevention.

Area of Science:

  • Wound Care
  • Dermatology
  • Nursing Research

Background:

  • Existing pressure ulcer classification systems lack interrater reliability evaluation.
  • The Shea classification is commonly used but may not fully describe ulcer healing.
  • A need exists for a more comprehensive pressure ulcer grading scale.

Purpose of the Study:

  • To evaluate the interrater reliability of the new Yarkony-Kirk pressure ulcer scale.
  • To compare the Yarkony-Kirk scale with the Shea classification.
  • To assess the Yarkony-Kirk scale's ability to describe pressure ulcer healing more completely.

Main Methods:

  • Two nurses independently assessed 72 patients using both the Yarkony-Kirk scale and the Shea classification.
  • Interrater reliability was measured using correlation coefficients and percentage of identical ratings.

  • The Yarkony-Kirk scale includes grades for red areas, epidermis/dermis, subcutaneous fat, muscle, bone, joint space, and healed ulcers.

    • Main Results:

    • The Yarkony-Kirk scale demonstrated excellent interrater reliability (correlation = 0.90) compared to the Shea classification (correlation = 0.86).
    • Eighty-five percent of Yarkony-Kirk ratings were identical, versus 68% for the Shea classification.
    • The Yarkony-Kirk scale showed a lower percentage of ratings differing by more than one category (6% vs. 3%).

    Conclusions:

    • The Yarkony-Kirk scale possesses good interrater reliability and provides a more complete description of pressure ulcers.
    • This scale can aid in teaching prevention strategies and ulcer classification.
    • The Yarkony-Kirk scale offers advantages in assessing early-stage ulcers and healed sores.
