The palliative performance scale: examining its inter-rater reliability in an outpatient palliative radiation oncology clinic

Abstract

PPS was shown to have good overall inter-rater reliability in an outpatient palliative setting, but more research is needed to establish the validity and reliability of the tool in a variety of different palliative settings.

Nurse and physician inter-rater agreement of three performance status measures in palliative care outpatients

“…For the PPS, inter-rater agreement has only been compared in one clinical study [6], which found better correlation between scores rated by a physician and research assistant (Spearman rank correlation, r=0.86) than between the physician and radiation therapist (r=0.77). The reliability and validity of the PPS was recently assessed using web-based scenarios; two combined groups of physicians and nurses rated PS based on 11 scenarios, and the ratings of the two groups were compared [26].…”

Comfort level of caregivers of cancer patients receiving palliative care

“…The scale has eleven levels, from zero to 100%, divided in intervals of 10. A 100% level means that the patient is fully functional, and zero means death 15 .…”

Enhancing Communication in End‐of‐Life Care: A Clinical Tool Translating Between the Clinical Frailty Scale and the Palliative Performance Scale

“…Although interrater reliability has been validated for the CFS and the PPS, interrater reliability of the scores assigned was established to ensure the accuracy of the scores for the conversion chart. Interrater reliability within each measure was determined by comparing the scores that nurses and physicians within each specialty assigned.…”
