Factor analysis and correlation between CIWA-Ar protocol and biochemical-hematic profile in patients with alcohol withdrawal syndrome

Background CIWA-Ar score is the gold standard for stratifying severity of alcohol withdrawal syndrome (AWS). Aim To identify the correlation between the different scales used in patients with AWS, and with the biochemical–haematological profile. Material and methods Prospective, analytical observational study in 49 patients with AWS diagnosed between February 2011 and July 2012. Maddrey, Glasgow, MELD, CIWA-Ar scores and laboratory values were obtained at diagnosis. Results There was no correlation between CIWA-Ar and other scales (R2 = 0.001, p = 0.823, 95%CI); however, a linear relationship (p = 0.000, 95%CI) was found. On the correlation matrix, CIWA-Ar was not associated with any of the study parameters. There were no significant differences in length of stay when analyzed by type of treatment. Conclusion CIWA-Ar is a good predictor of severity, albeit with no biochemical or hematic correlation.
