Summary

The Karnofsky Performance Status (KPS) and ECOG performance scales show good reliability among raters. The ECOG scale demonstrated slightly better interobserver agreement, minimizing observer differences in oncology patient assessments.

Area of Science:

  • Oncology
  • Clinical Assessment
  • Biostatistics

Background:

  • Performance status scales are crucial for evaluating cancer patient prognosis and treatment efficacy.
  • The Karnofsky Performance Status (KPS) and Eastern Cooperative Oncology Group (ECOG) scales are widely used but require assessment of their interobserver reliability.

Purpose of the Study:

  • To compare the interobserver reliability and agreement between the KPS and ECOG performance scales.
  • To determine which scale offers better consistency among different raters in a medical oncology setting.

Main Methods:

  • 100 consecutive oncology patients were assessed using both KPS and ECOG scales.
  • Assessments were performed by three independent raters and the patients themselves.
  • Statistical analysis was used to evaluate agreement and interobserver variability.

Main Results:

  • High agreement was observed between most paired assessors for both scales.
  • The ECOG scale showed better agreement, particularly between RMO/patient and nurse/patient pairs, compared to KPS.
  • Individual raters showed no statistical difference between the scales, with good overall agreement for both.

Conclusions:

  • Both KPS and ECOG scales can be utilized with good interobserver reliability in oncology.
  • The ECOG scale is recommended for its ability to minimize interobserver variability and differences between raters.
