  • Calculating Multi-Rater Observation Agreement in Health Care Research Using the SAS® Kappa Statistic

  • The processes are described for calculating multi-rater observation agreement using the SAS® kappa statistic in a health care research study of the medication administration process (MAP). Registered nurses modeled the oral MAP a total of 27 times in a simulated laboratory environment. Four individuals observed each of the 27 modeling sessions and recorded the MAP functions and tasks observed for each session. Inter-rater reliability (IRR) among the four observers was examined using the kappa statistic and calculated using the SAS® FREQ, MEANS, and PRINT procedures. Results from pairwise comparisons ranged from fair to good. This technique expands the current functionality of the FREQ procedure to support kappa statistical analysis for more than two raters and several categories.
