AIM： To test the psychometric properties of a Chinese [（Hong Kong） HK] translation of the chronic liver disease questionnaire （CLDQ）. METHODS： A Chinese （HK） translation of the CLDQ was developed by iterative translation and cognitive debriefing. It was then administered to 72 uncomplicated and 78 complicated chronic hepatitis B （CriB） patients in Hong Kong together with a structured questionnaire on service utilization, and the Chinese （HK） SF-36 Health Survey Version 2 （SF-36v2）. RESULTS： Scaling success was ≥ 80% for all but three items. A new factor assessing sleep was found and items of two （Fatigue and Systemic Symptoms） subscales tended to load on the same factor. Internal consistency and test-retest reliabilities ranged from 0.58-0.90 for different subscales. Construct validity was confirmed by the expected correlations between the SF-36v2 Health Survey and CLDQ scores. Mean scores of CLDQ were significantly lower in complicated compared with uncomplicated CHB, supporting sensitivity in detecting differences between groups.CONCLUSION： The Chinese （HK） CLDQ is valid, reliable and sensitive for patients with CHB. Some modifications to the scaling structure might further improve its psychometric properties,

BACKGROUND:This study aimed to evaluate the discriminatory performance of 11 vital sign-based early warning scores(EWSs)and three shock indices in early sepsis prediction in the emergency department(ED).METHODS:We performed a retrospective study on consecutive adult patients with an infection over 3 months in a public ED in Hong *** primary outcome was sepsis(Sepsis-3 definition)within 48 h of ED *** c-statistics and the DeLong test,we compared 11 EWSs,including the National Early Warning Score 2(NEWS2),Modified Early Warning Score,and Worthing Physiological Scoring System(WPS),etc.,and three shock indices(the shock index[SI],modified shock index[MSI],and diastolic shock index[DSI]),with Systemic Inflammatory Response Syndrome(SIRS)and quick Sequential Organ Failure Assessment(qSOFA)in predicting the primary outcome,intensive care unit admission,and mortality at different time ***:We analyzed 601 patients,of whom 166(27.6%)developed ***2 had the highest point estimate(area under the receiver operating characteristic curve[AUROC]0.75,95%CI 0.70-0.79)and was significantly better than SIRS,qSOFA,other EWSs and shock indices,except WPS,at predicting the primary ***,the pooled sensitivity and specificity of NEWS2≥5 for the prediction of sepsis were 0.45(95%CI 0.37-0.52)and 0.88(95%CI 0.85-0.91),*** discriminatory performance of all EWSs and shock indices declined when used to predict mortality at a more remote time ***:NEWS2 compared favorably with other EWSs and shock indices in early sepsis prediction but its low sensitivity at the usual cut-off point requires further modification for sepsis screening.
