Association Between Preoperative Frailty Using Frailty Index-Laboratory Test and Clinical Outcomes in Older Adults Undergoing Brain Tumor Surgery.
Sang Ok Kim, Youn-Jung Son, JiYeon Choi
PMID 40545253WHAT IT FOUND
Frailty from routine blood tests and vital signs before brain tumor surgery was not linked to longer hospital stay, but it was linked to more 90-day readmissions and more non-home discharge, though only 8 patients had high frailty.
Key findings
01Moderate frailty was associated with 90-day readmission odds 1.5 times higher than low frailty (95% CI 1.01 to 1.82).
02High frailty was associated with non-home discharge odds 2.1 times higher than low frailty (95% CI 1.03 to 2.99).
03Frailty level was not significantly associated with hospital length of stay in adjusted analysis (moderate p = 0.063, high p = 0.551).

What it does not show
The study was retrospective and done at one hospital, so it can show association but not cause. Only 8 patients were in the high-frailty group, so that group's results are imprecise and should not be treated as stable. Frailty was scored only from laboratory tests and vitality signs, not from a full assessment of function, mood, cognition, or social support. Patients with more than 30% missing FI-LAB items were excluded, which may limit generalizability. Laboratory and vitality values were not always recorded on the same day, which may affect frailty scores. The study did not test whether using the FI-LAB changes care or improves outcomes.
Declared interests
The authors declared no conflicts of interest. The work was funded by the National Research Foundation of Korea.
The easy way to misread this
Do not conclude that preoperative frailty screening caused readmission or non-home discharge, or that using the FI-LAB will improve outcomes. This was a retrospective association study, not a trial, and only 8 patients were in the high-frailty group.
