Objectives: This study aimed to assess the prevalence of frailty in cirrhosis patients and the distribution of age, sex, and body mass index (BMI) in cirrhotic patients with frailty.
Methods: We performed a thorough literature search using PubMed, Embase, Web of Science, and the Cochrane Library from inception to 29 February 2024. The estimated prevalence with a 95% confidence interval (CI) was calculated with a random effect model. Subgroup analysis and sensitivity analysis were performed to assess the heterogeneity and characterize the distribution of age, sex, and body mass index (BMI) in cirrhotic patients. Publication bias was assessed by the funnel plot, Begg's test, and Egger's test.
Results: The 16 included studies, which were all observational, reported a prevalence of frailty in 8,406 cirrhosis patients ranging from 9 to 65%, and the overall estimated prevalence was 27% (95% CI: 21-33%; I2 = 97.7%, P < 0.001). This meta-analysis indicated that the estimated prevalence of frailty in cirrhosis patients was high, and compared to the non-frail cohort, the frail cohort tended to have a higher mean age, with a mean age of 63.3 (95% CI: 59.9, 66.7; Z = 36.48; P < 0.001), and a larger proportion of male patients with worse liver function, with a mean of 73.5% (95% CI: 71.4, 75.5%; Z = 7.65; P < 0.001), ND in the frail cohort, 54.8% (95% CI: 43.1, 66.5%; P < 0.001) and 23.4% (95% CI: 13.2, 33.7%; P < 0.001) were classified into Child-Pugh B and C, respectively. Meanwhile, the patients in the non-frail cohort are more likely to have a higher BMI, with a mean of 28.4 (95% CI: 24.1, 32.7; Z = 13.07; P < 0.001).
Conclusion: The current study suggests that cirrhosis patients have a high prevalence of frailty. Compared with the non-frail cohort, the frail patients tend to be male, older, and have a lower BMI with worse liver function.
