چکیده

BACKGROUND Subjective scoring of pupil reactivity is a fundamental element of the neurological examination for which the pupillometer provides an objective measure. METHODS This single-blinded observational study examined interrater reliability of pupil exam findings between two practitioners and between practitioners and a pupillometer. RESULTS From 2329 paired assessments, the interrater reliability between practitioners was only moderate for pupil size (k = 0.54), shape (k = 0.62), and reactivity (k = 0.40). Only 33.3% of pupils scored as non-reactive by practitioners were scored as non-reactive by pupillometry. CONCLUSIONS Despite the strong emphasis placed on the traditional pupil examination, especially for patients with a neurological illness, there is limited interrater reliability for subjective scoring of pupillary assessments. Thus, the use of automated pupillometers should be examined as a potential method to increase the reliability of measuring of pupil reactivity.

Reliability of the Modified Motor Assessment Scale and the Barthel Index.

Many physical therapists use descriptive and functional assessments of motor recovery for patients with stroke. The purpose of this study was to establish the reliability of two such assessments. The Modified Motor Assessment Scale (MMAS) assesses motor recovery; the Barthel Index assesses functional independence. Interrater and intrarater reliability were determined for the total scores and in...

Cost Implications of Interrater Agreement for Software Process Assessments

Much empirical research has been done recently on evaluating and modeling interrater agreement in software process assessments. Interrater agreement is the extent to which assessors agree in their ratings of software process capabilities when presented with the same evidence and performing their ratings independently. This line of research was based on the premise that lack of interrater agreem...
