Impact of Inadequate Nutrition in Lung Transplant Recovery: A Meta-Analysis

Background: We aimed to appraise and compare the impact of inadequate nutrition in lung transplant recovery. Methods: Based on the inspection of the meta-analysis data, the odds ratio (OR) and mean difference (MD) with 95% confidence intervals (CIs) were derived by dichotomous random or fixed effect models. 6 papers with 1399 lung transplant who were available between 2020 and 2024 were comprised in this meta-analysis. Results: Frail had significantly higher hospital length of stay (MD, 2.80; 95% CI, 1.80-3.80, P< 0.001), and allcause mortality (OR, 2.33; 95% CI, 1.40-3.87, P=0.001) compared to non-frail in subjects with lung transplant. However, no significant difference was found between frail and non-frail in intubation post-lung transplant (MD, 7.00; 95% CI, -17.52-31.52, P=0.58), and intensive care unit length of stay (MD, -1.70; 95% CI, -4.53Conclusion: Using frail had significantly higher hospital length of stay, and all-cause mortality, however, no significant difference was found in intubation post-lung transplant, and intensive care unit length of stay compared to non-frail in subjects with lung transplant However, given that comparisons comprised a small number of studies, attention ought to be given to their values.
