Kilkenny MF, Phan HT, Lindley RI, et al. - Researchers evaluated relationships between a published, generic frailty risk score, derived from administrative data, and patient outcomes following stroke/transient ischemic attack; and its accuracy for stroke in anticipating mortality compared with other measures of clinical status using coded data. Hospital admissions data were connected with patient-level data from the Australian Stroke Clinical Registry (2009–2013). Among 15,468 adult individuals, 15% died ≤ 90 days. Greater frailty was linked to poorer outcomes after a stroke or transient ischemic attack. When assessing risk-adjusted outcomes following a stroke/transient ischemic attack, the Frailty Score has the same precision as the Charlson and Elixhauser indices.
