PMID 30208156WHAT IT FOUND
In 243 adults aged 80 or over, hospitalization in the last 12 months was associated with physical frailty.
A model that included hospitalization, dyslipidemia and metabolic disease identified 55.5% to 58.3% of frail participants.
Key findings
01The final sample was 243 oldest-old participants: 36 were frail, 155 pre-frail and 52 non-frail.
02Hospitalization in the last 12 months was associated with physical frailty (p=0.0454).
03The selected model had sensitivity of 55.5% to 58.3% and specificity of 66.6% to 67.1%.

What it does not show
The study was cross-sectional, so it cannot establish causal relations between clinical variables and frailty. The sample came from three Basic Health Units in Curitiba, Paraná, so the results cannot be generalized. The selected model was modestly accurate: it identified 55.5% to 58.3% of frail participants and 66.6% to 67.1% of non-frail participants. Thirty-six participants could not answer the research questions, so family caregivers provided information for some assessments.
The easy way to misread this
Do not read recent hospitalization or dyslipidemia as causes of physical frailty. The study was cross-sectional, so it cannot establish causal relations, and the selected model identified only 55.5% to 58.3% of frail participants.
