Background:
The Geriatric Nutritional Risk Index (GNRI) is associated with readmission risk in older inpatients, but evidence is from single-centre studies.
Aim:
To quantify the association between GNRI and readmission risk, total hospital stay and intensive care unit (ICU) stay in older hospitalized patients.
Methods:
Searched Cochrane Library, Web of Science, PubMed and Embase until 23 October 2024 for case-control or cohort studies on GNRI and readmission in patients aged ≥60. Study quality was assessed using the Newcastle-Ottawa Scale. Analyses were performed in Stata 15.0 using random- or fixed-effects models based on heterogeneity (I2≥50%, p < 0.05). Effect sizes were reported as relative risk (RR) or standardized mean difference (SMD) with 95% confidence intervals (CI). Subgroup and sensitivity analyses were conducted.
Results:
Thirty-six studies were included. Twelve studies (n = 234,116) confirmed lower readmission risk in the high-GNRI group (RR = 0.60, 95%CI: 0.53-0.68; I2 = 70.8%). Twenty-six studies (n = 30,461) showed shorter total hospital and ICU stays.
Conclusions:
Lower GNRI is significantly associated with higher readmission risk and longer total hospital and ICU stays in older inpatients, supporting its role as a biomarker for adverse outcomes.
