Assessing clinical frailty scale scoring by junior medical learners on an inpatient geriatrics consultation service

The Clinical Frailty Scale (CFS) is incorporated into our institution's comprehensive geriatric assessment (CGA). CGAs and CFS scoring are completed by junior medical trainees on the Geriatric consult service. The agreement between CFS score assignment by junior trainees and Geriatrics trained individuals in this setting is unknown. Importantly, these scores assign a frailty level that impacts care pathways. We conducted a retrospective chart review from April-June 2019. A Geriatric medicine subspecialty resident assigned retrospective CFS scores based on data from the CGA. We compared scores to determine the level of agreement using the Cohen and Conger's Kappa inter-rater agreement metric and assessed whether patient characteristics influenced the likelihood of agreement between raters using a generalized linear model. Medical students assessed 43% (46/108) of patients (n = 13), and 57% (62/108) were assessed by PGY1s (n = 10). Inter-rater agreement measures showed substantial agreement overall and for PGY1s, but dropped to a moderate agreement for medical students. The retrospective inter-rater agreement of the CFS showed substantial agreement overall and decreased when limited to medical students, highlighting the need for interventions to improve the understanding of frailty early in medical training.
