We assessed the correlations of the Frailty Instrument for primary care of the Survey of Health,Ageing and Retirement in Europe (SHARE-FI on admission: non-frail, pre-frail, frail) with the outcomes of aShort-term Post-Acute Rehabilitative Care programme (N=172 admissions over one-year period, 95 of whichwere frail). SHARE-FI correlated with age (non-frail: mean 79.2 years; frail: 83.6; P<0.001). Adjusting for age,SHARE-FI correlated with longer length of stay (non-frail: median 30 days; frail: 42; P=0.047), higher rate ofemergency transfer to acute hospital (non-frail: 2.4%; frail: 21.1%; P=0.004), and lower home discharge rate(non-frail: 97.6%; frail: 81.9%; P=0.009). While frailty correlated with more disability on admission anddischarge, there was no statistically significant difference in Barthel Index (BI) improvement across frailtycategories (all groups had median BI improvement of ≥2 points, P=0.247). The post-acute rehabilitation of thefrail is worthwhile but requires more time and access to acute hospital facilities.
