A Clinical Decision Rule Based on the AST-to-Platelet Ratio Index Improves Adherence to Published Guidelines on the Management of Acute Variceal Bleeding.

BACKGROUND: Optimal management of acute upper gastrointestinal bleeding (UGIB) depends on identifying a variceal versus nonvariceal etiology. An objective measure predicting etiology could guide early management pending endoscopy. The AST-to-platelet ratio index (APRI) score has been studied as a marker of cirrhosis and portal hypertension, but has not been evaluated in the setting of acute UGIB. METHODS: In this single-center retrospective cohort study, we reviewed endoscopy reports and other data for patients with acute UGIB, and classified episodes as variceal bleeds or other. We assessed the diagnostic utility of the APRI score relative to other objective measures by Area Under the Receiver Operating Characteristic (AUROC) curve analysis. We constructed a clinical decision rule based on the APRI score, and assessed how it would have changed management. RESULTS: The APRI score performed well in predicting a variceal etiology of acute UGIB, with AUROC 0.89. We developed a clinical decision rule using an APRI score of 0.4 to guide early management of acute UGIB patients. Retroactively applying this to our cohort, adherence to published guidelines for administration of octreotide and antibiotics would have increased from 56% to 91%. CONCLUSIONS: The APRI score is an objective metric that helps predict a variceal etiology of acute UGIB. Using our proposed decision rule could improve adherence to guidelines on management of acute variceal bleeding. Although we were unable to demonstrate a survival benefit, improved adherence to evidence-based guidelines serves as a metric related to this most important outcome measure. Prospective study to validate these findings is indicated.

Training directors have positive perceptions of a competency-based gastroenterology and transplant hepatology fellowship program.

BACKGROUND & AIMS: In 2012, the American Board of Internal Medicine approved a pilot competency-based transplant hepatology (TH) training program. This program allows gastroenterology (GI) and TH fellowships to be completed in 3 years. We investigated the perceptions and beliefs of GI and TH division and fellowship program directors on the competency-based TH training program. METHODS: All current GI and TH division and fellowship program directors from the 162 fellowship programs accredited by the Accreditation Council for Graduate Medical Education were invited via e-mail to anonymously complete the online survey. The survey questioned their perceptions of the 3-year combined GI and TH training program. RESULTS: A total of 116 participants completed the survey (∼38% response rate). Most respondents were GI fellowship directors (61%); 15% were GI and hepatology division directors, 19% were TH fellowship directors, 14% were TH division directors, and 5% were GI division directors. Most of the respondents were in favor of the pilot program (85%). Only 63% of all respondents believed that graduates of the pilot program would achieve the same level of competency in GI as those who completed the traditional program. Overall, 71% believed incorporation of the 3-year training model would increase interest and participation in TH fellowships. CONCLUSIONS: Most of the academic GI and TH division and fellowship program directors embrace competency-based fellowship education and TH subspecialty training during the designated 3-year GI fellowship. Future studies will be needed to reevaluate these beliefs after several years.

Hepatitis C risk assessment, testing and referral for treatment in urban primary care: role of race and ethnicity.

AIM: To determine rates of hepatitis C (HCV) risk factor ascertainment, testing, and referral in urban primary care practices, with particular attention to the effect of race and ethnicity. METHODS: Retrospective chart review from four primary care sites in Philadelphia; two academic primary care practices and two community clinics was performed. Demographics, HCV risk factors, and other risk exposure information were collected. RESULTS: Four thousand four hundred and seven charts were reviewed. Providers documented histories of injection drug use (IDU) and transfusion for less than 20% and 5% of patients, respectively. Only 55% of patients who admitted IDU were tested for HCV. Overall, minorities were more likely to have information regarding a risk factor documented than their white counterparts (79% vs 68%, P < 0.0001). Hispanics were less likely to have a risk factor history documented, compared to blacks and whites (P < 0.0001). Overall, minorities were less likely to be tested for HCV than whites in the presence of a known risk factor (23% vs 35%, P = 0.004). Among patients without documentation of risk factors, blacks and Hispanics were more likely to be tested than whites (20% and 24%, vs 13%, P < 0.005, respectively). CONCLUSION: (1) Documentation of an HCV risk factor history in urban primary care is uncommon, (2) Racial differences exist with respect to HCV risk factor ascertainment and testing, (3) Minority patients, positive for HCV, are less likely to be referred for subspecialty care and treatment. Overall, minorities are less likely to be tested for HCV than whites in the presence of a known risk factor.

Description of a new hepatitis C risk assessment tool.

BACKGROUND: Because of the low prevalence of hepatitis C virus (HCV) infection in the general population, mass screening would be expensive and of low yield. Some researchers advocate targeted screening of persons at elevated HCV risk. METHODS: This cross-sectional study aimed to develop a patient-administered tool to assess HCV infection risk. Two hundred seven patients with unknown HCV status from a general medicine practice and 222 HCV-positive patients from a hepatology practice completed a 72-item survey about demographic, social, and clinical risk factors for HCV infection. General medicine patients also underwent HCV serologic testing. RESULTS: Three (1.5%) of 207 general medicine patients had positive HCV antibody test results. These patients plus the 222 hepatology patients were significantly more likely than HCV-negative patients to report an array of factors. In a multivariable model, 7 factors remained significantly associated with HCV infection: sex with a prostitute or an injecting drug user, exposure to blood products, refusal as a blood donor or as a life insurance applicant, witnessing illicit drug use, and self-reported HBV infection. A simplified model that assigned 1 point for each factor present predicted HCV infection as well as a weighted model (based on chi(2) testing and receiver operating characteristic curve comparison). In a population with a 2% prevalence of HCV infection, people who identified 2 risk factors had a 10% chance of HCV infection, whereas those with 4 or more risk factors had a 50% chance. CONCLUSIONS: A self-administered 72-item questionnaire can stratify patients into HCV risk groups. If validated in other primary care populations, this instrument could help target HCV screening.

Approach to the patient with chronic hepatitis C virus infection.

Chronic hepatitis C virus (HCV) infection is common and often asymptomatic. Antibodies against HCV are a highly sensitive marker of infection. Molecular testing for HCV is used to confirm a positive result on antibody testing and to provide prognostic information for treatment; however, quantitative HCV RNA does not correlate with disease severity or risk for progression. Chronic HCV infection is most frequently associated with remote or current intravenous drug use and blood transfusion before 1992, although as many as 20% of infected patients have no identifiable risk factor. In an estimated 15% to 20% of persons infected with HCV, the infection progresses to cirrhosis; alcohol intake is an important cofactor in this progression. Most specialists prefer to include an examination of liver histology in the management of patients with chronic HCV infection to aid prognostic and treatment decisions. The current standard of pharmacologic treatment of chronic HCV is weekly subcutaneous peginterferon in combination with daily oral ribavirin, which results in sustained virologic response in approximately 55% of chronically infected patients. Side effects of interferon therapy include myalgias, fever, nausea, irritability, and depression. The cost-effectiveness of interferon therapy is similar to that of many commonly accepted medical interventions. The primary care physician serves a vital role in identifying patients with chronic HCV infection, educating patients about risk factors for transmission, advising patients about the avoidance of alcohol, and aiding patients in making treatment decisions.
