OBJECTIVES: Chronic liver disease (CLD) is an important cause of morbidity and mortality, but the epidemiology is not well described. We conducted prospective population-based surveillance to estimate newly diagnosed CLD incidence, characterize etiology distribution, and determine disease stage. METHODS: We identified cases of CLD newly diagnosed during 1999–2001 among adult county residents seen in any gastroenterology practice in New Haven County, Connecticut; Multnomah County, Oregon; and Northern California Kaiser Permanente Medical Care Program (KPMCP, Oakland, California [total population 1.48 million]). We defined CLD as abnormal liver tests of at least 6 months' duration or pathologic, clinical, or radiologic evidence of CLD. Consenting patients were interviewed, a blood specimen obtained, and the medical record reviewed. RESULTS: We identified 2,353 patients with newly diagnosed CLD (63.9 cases/100,000 population), including 1,225 hepatitis C patients (33.2 cases/100,000). Men aged 45–54 yr had the highest hepatitis C incidence rate (111.3/100,000). Among 1,040 enrolled patients, the median age was 48 yr (range 19–86 yr). Hepatitis C, either alone (442 [42%]) or in combination with alcohol-related liver disease (ALD) (228 [22%]), accounted for two-thirds of the cases. Other etiologies included nonalcoholic fatty liver disease (NAFLD, 95 [9%]), ALD (82 [8%]), and hepatitis B (36 [3%]). Other identified etiologies each accounted for <3% of the cases. A total of 184 patients (18%) presented with cirrhosis, including 44% of patients with ALD. CONCLUSIONS: Extrapolating from this population-based surveillance network to the adult U.S. population, approximately 150,000 patients with CLD were diagnosed in gastroenterology practices each year during 1999–2001. Most patients had hepatitis C; heavy alcohol consumption among these patients was common. Almost 20% of patients, an estimated 30,000 per year, had cirrhosis at presentation. These results provide population-level baseline data to evaluate trends in identification of patients with CLD in gastroenterology practices. [ABSTRACT FROM AUTHOR]

Background: Hepatitis C virus (HCV) antiviral therapy entails a long treatment course, as well as significant side effects that can lead to medication non-adherence and premature termination of treatment. Few large studies have comprehensively examined patient perspectives on the treatment experience, particularly the social and personal effects., Objective: We sought to understand how a diverse group of patients' lives were affected during HCV treatment, and to obtain suggestions about how to better support patients during treatment., Methods: On average, 13 months after therapy we interviewed by telephone a consecutive sample of 200 patients treated for hepatitis C with ribavirin and pegylated interferon in a comprehensive, integrated health plan in the years 2008-2010. Mixed (quantitative and qualitative) survey methods were used., Results: The response rate was 68.9 %. Mean age at treatment was 51 years; 63.0 % were men; and Black, Hispanic, Asian, and White non-Hispanic racial/ethnic groups were similarly represented. Patients whose treatment was managed by nurses or clinical pharmacists (vs. physicians) were more likely to report their providers as being part of their support system (83.5 % vs. 58.9 %; p < 0.001). Most patients reported flu-like symptoms (93.5 %) and psychiatric problems (84.5 %), and 42.5 % reported side effects lasted up to 6 months after treatment. Black patients reported discontinuing treatment prematurely due to side effects more often than non-Blacks (29.4 % vs. 12.1 %; p < 0.001). Physical side effects (69.5 % of patients), psychiatric issues (43.5 %), and employment (27.4 %) were ranked among the three most difficult challenges. Patients desired help in anticipating and arranging work modifications during treatment. Most patients rated peer support, nutritional guidance, and weekly provider contact by telephone as potentially helpful resources for future patients undergoing HCV treatment., Conclusions: Patient perspectives can help formulate and refine HCV treatment support programs. Effective support programs for diverse populations are crucial as the complexities and costs of HCV treatment increase. The call for greater support from peers, providers, and employers demands new systems such as patient-centered care teams.

Goals: To examine a wide range of sociodemographic and clinical characteristics as potential predictors of complementary and alternative medicine (CAM) use among chronic liver disease (CLD) patients, with a focus on CAM therapies with the greatest potential for hepatotoxicity and interactions with conventional treatments., Background: There is some evidence that patients with CLD commonly use CAM to address general and CLD-specific health concerns., Study: Patients enrolled in a population-based surveillance study of persons newly diagnosed with CLD between 1999 and 2001 were asked about current use of CAM specifically for CLD. Sociodemographic and clinical information was obtained from interviews and medical records. Predictors of CAM use were examined using univariate and multivariate logistic regression analysis., Results: Of the 1040 participants, 284 (27.3%) reported current use of at least 1 of 3 CAM therapies of interest. Vitamins or other dietary supplements were the most commonly used therapy, reported by 188 (18.1%) patients. This was followed by herbal medicine (175 patients, 16.8%) and homeopathy (16 patients, 1.5%). Several characteristics were found to be independent correlates of CAM use: higher education and family income, certain CLD etiologies (alcohol, hepatitis C, hepatitis C and alcohol, and hepatitis B), and prior hospitalization for CLD., Conclusions: Use of CAM therapies that have the potential to interact with conventional treatments for CLD was quite common among this population-based sample of patients with CLD. There is a need for patient and practitioner education and communication regarding CAM use in the context of CLD.

Unlabelled: Standard death certificate-based methods for ascertaining deaths due to chronic liver disease (CLD), such as the U.S. vital statistics approach, rely on a limited set of diagnostic codes to define CLD. These codes do not include viral hepatitis or consider hepatocellular carcinoma (HCC) deaths, and thus, underestimate the true burden of CLD mortality. Deaths associated with CLD may be further misunderstood because of the inherent limitations of death record information. Using a comprehensive list of CLD-related codes to search death records, we investigated the CLD mortality rate and associated etiologies (derived from medical records) in a large managed care health plan. From the 16,970 deaths among health plan members in 2000, we confirmed 355 (2.1%) as CLD related, including 75 with HCC. The age-adjusted CLD mortality rate using the comprehensive codes was 11.9 per 100,000 compared with 6.3 per 100,000 using only conventional codes. Based on medical records, the underlying CLD was attributed to alcoholic liver disease (ALD) in 44% of deaths, HCV infection with ALD in 16%, HCV without ALD in 18%, and chronic HBV infection in 7%. Only 64% of HCV-associated, 48% of HBV-associated, and 64% of ALD-associated deaths ascertained by medical record had that specific etiology mentioned on the death certificate., Conclusion: CLD mortality burden was almost doubled by using a comprehensive list of mortality codes and considering HCC deaths as CLD related. Furthermore, the contributions of viral hepatitis and ALD to CLD mortality may be underestimated if based solely on death records.
