This new

subdomain structure was used for IRT-based scoring. Unlike traditional CLDQ scores, IRT-based scores closely approximated a normal distribution. With traditional CLDQ scoring, LD severity significantly influenced both general QOL scores and subdomain scores (ANOVA p<0.05). While LD severity significantly influenced IRT-based general QOL scores it did not significantly influence IRT-based subdo-mains www.selleckchem.com/products/dabrafenib-gsk2118436.html scores. Traditional subdomain scores correlated highly with general QOL scores (r>0.7), while IRT-based subdomain scores did not. When the effect of general QOL on traditional subdomain scores was accounted for, the influence of non-LD-related factors on traditional subdomain scores was greatly reduced. Interestingly, when the effect of general QOL was accounted for, the influence of LD severity on traditional subdo-main scores was no longer significant. CONCLUSIONS: The strong influence of general QOL on “LD-specific” subdomain scores from the CLDQ renders them susceptible to the influence of non-liver disease-related factors and causes their clinical significance to be overestimated. This study questions the clinical utility of CLDQ subdomain

scores. Disclosures: this website Robert Gibbons – Stock Shareholder: Psychiatric Assessments Inc. The following people have nothing to disclose: Sujit V.

Beiser Background: Of the 3 million Americans chronically infected with Hepatitis C virus (HCV), it is estimated that only 25-50% are aware of their diagnosis. In August 2012, the CDC released recommendations for one-time HCV testing in persons born between 1945-1965 to improve screening in individuals at highest risk for chronic HCV infection. Aims: This study aims to assess the rate of HCV screening, follow-up testing, and linkage to care in an academic

primary care practice, selleckchem before and after the CDC birth cohort guidelines. Methods: All patients born 1945-1965 and seen in the primary care clinic at the University of Chicago from July 1st, 2010 to May 15th, 2013 were included in the study. Key demographics, results of HCV-related laboratory testing, and completion of hepatology follow-up were obtained from the electronic medical record database. All patients seen from July 2012 to May 2013 were identified as the post-guideline group. MedCalc software (medcalc.org) was used for statistical analysis as appropriate. Results: A total of 24,947 patients in the eligible birth cohort were identified; 16,811 and 8,066 fell in the pre- and post-guideline groups, respectively. Only one third of patients in the birth-cohort had screening by HCV antibody testing and this rate continued to be low in the post-guideline group (Table 1). For patients screening positive, rates of confirmatory testing with viral load, genotype analysis and referral to hepatology were high in both the pre- and post-guideline group (Table 1).
