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

Abstract

To create a clinical tool to translate between the Clinical Frailty Scale (CFS), which geriatrics teams use, and Palliative Performance Scale (PPS), which palliative care teams use, to create a common language and help improve communication between geriatric and palliative care teams. Cross-sectional. Two academic health centers: inpatient palliative care and chronic care units, an outpatient geriatric clinic, and inpatient referrals to a palliative care consultation service. Older adults (≥65) aged 80.9±8.0, with malignant (51%) and nonmalignant (49%) terminal diagnoses (N=120). Each participant was assigned four scores: a CFS score each from a geriatric physician and nurse and a PPS score each from a palliative care physician and nurse. Interrater reliability of each measure was calculated using kappa coefficients. For each measure, the mean of physician and nurse scores was used to calculate every possible combination of CFS and PPS scores to determine the combination with maximum agreement. Interrater reliability of each measure was very high for the CFS (weighted κ=0.92) and PPS (weighted κ=0.80). The CFS-PPS score matching that achieved maximum agreement (weighted κ=0.71) was used to create a conversion chart between the two measures. This conversion chart is a reliable means of translating scores between the CFS and PPS and is useful for geriatric and palliative care teams collaborating in the care of elderly adults.
