Highly efficacious and tolerable treatments that cure hepatitis C viral (HCV) infection exist today, increasing the feasibility of disease elimination. However, large healthcare systems may not be fully prepared for supporting recommended actions due to knowledge gaps, inadequate infrastructure and uninformed policy direction. Additionally, the HCV cascade of care is complex, with many embedded barriers, and a significant number of patients do not progress through the cascade and are thus not cured. The aim of this retrospective cohort study was to evaluate a large healthcare system’s HCV screening rates, linkage to care efficiency, and provider testing preferences. Patients born during 1945–1965, not previously HCV positive or tested from within the Electronic Health Record (EHR), were identified given that three-quarters of HCV-infected persons in the United States are from this Birth Cohort (BC). In building this HCV testing EHR prompt, non-Birth Cohort patients were excluded as HCV-specific risk factors identifying this population were not usually captured in searchable, structured data fields. Once completed, the BC prompt was released to primary care locations. From July 2015 through December 2016, 11.5% of eligible patients (n = 9,304/80,556) were HCV antibody tested (anti-HCV), 3.8% (353/9,304) anti-HCV positive, 98.1% (n = 311/317) HCV RNA tested, 59.8% (n = 186/311) HCV RNA positive, 86.6% (161/186) referred and 76.4% (n = 123/161) seen by a specialist, and 34.1% (n = 42/123) cured of their HCV. Results from the middle stages of the cascade in this large healthcare system are encouraging; however, entry into the cascade–HCV testing–was performed for only 11% of the birth cohort, and the endpoint–HCV cure–accounted for only 22% of all infected. Action is needed to align current practice with recommendations for HCV testing and treatment given that these are significant barriers toward elimination.
Objective. CDC recommends that all people born between 1945 and 1965 be tested for hepatitis C virus (HCV). We hypothesized that HCV testing in a large, urban primary care clinic would reveal higher rates of HCV infection than previously published.Methods. Through the Hepatitis Testing and Linkage to Care initiative, the primary care clinic at MedStar Washington Hospital Center in Washington, DC, provided HCV antibody (anti-HCV) testing and linkage to care from October 2012 through September 2013 for patients born between 1945 and 1965 without previously noted risk factors. We collected data on age, race/ethnicity, sex, anti-HCV and HCV ribonucleic acid (RNA) results, risk factors in those who tested anti-HCV positive, and health insurance type and made comparisons using χ 2 and Student's t-tests. Results.Of 1,123 patients tested, the mean age was 57 years, 742 (66.1%) were women, 969 (86.3%) were black/African American, and 654 (58.2%) had public health insurance. Of the 99 (8.8%) patients who tested anti-HCV positive, the mean age was 58 years, 54 were men, and 93 were black/African American; 41 of 74 anti-HCV-positive patients were intravenous drug users. Of 82 anti-HCV-positive patients, 51 were HCV RNA positive. Of the black/ African American patients tested, 49 of 317 men (15.5%) and 44 of 652 women (6.7%) were anti-HCV positive (p,0.001). The HCV prevalence rate in the birth cohort (8.8%) was significantly higher than the U.S. (3.3%) and DC (2.5%) rates (p,0.001), and the HCV prevalence rate among black/African American men in DC (15.5%) was substantially higher than the prevalence rate reported by CDC (8.1%). Conclusion.Testing initiatives in primary care settings need to be more rigorously upheld, and internal champions are needed to advocate for increased screening to ensure linkage to care and engagement in the HCV care cascade.
Hyponatremia (serum sodium concentration [Na+] < 136 mEq/L) is a potentially life-threatening condition. Recent evidence (Renneboog, Musch, Vandemergel, Manto, & Decaux, 2006) shows that even mild hyponatremia is associated with disorders of balance/gait. This retrospective analysis explored the influence of serum [Na+] on neuropsychological (NP) measurements at baseline from 44 patients with chronic hyponatremia who participated in an efficacy and safety study of an experimental compound over a decade ago. Group mean serum [Na+] was 124.8 ± 4.9 mEq/L. Age-adjusted partial correlations were computed between serum [Na+] and NP measurements, 39% of which were statistically significant--all involving psychomotor functioning. These findings replicate and extend previous observations that psychomotor deficits are, at least in part, associated with hyponatremia in these patients. While chronic hyponatremia is known to have deleterious effects on quality of life, motor and gait disturbances represent manifestations of mild hyponatremia that have until now gone unrecognized. A new class of medication, vasopressin antagonists, has been shown to correct hyponatremia. It will be important to explore the effects of correcting hyponatremia on psychomotor functioning in individuals with hyponatremia.
Objectives: CDC reported that 45% of Hepatitis C (HCV) infected people denied known risk factors. Electronic health record RF-based, non-Birth Cohort (born outside of years 1945–1965) screening is challenging as risk factors are often input as nonsearchable data. Testing non-Birth Cohort patients solely based on risk factors has the potential to miss a substantial number of HCV infected patients. The aim was to determine the HCV antibody positive prevalence who would have been missed had providers only followed risk factor based screening recommendations. Methods: A 1:3 case-control retrospective nested chart review was conducted. HCV risk factors and opioid prescriptions were manually abstracted from the Electronic Health Record; other variables were collected using Explorys. In July 2015 HCV screening data was collected on non-Birth Cohort patients who were HCV tested across MedStar Health, as a presumptive marker for high risk. Univariate and multivariate logistic regression models were utilized to determine HCV antibody positive predictors. Results: Eighteen (23%) HCV antibody positive and 123 (49%) HCV antibody negative had no identified risk factors; 6 (33%) HCV antibody positive reported risk factors only after a positive test result. There was a significant interaction between age over 40 and opioid prescription use; these groups were 11× more likely to be HCV antibody positive (CI95 1.6–74.8). Conclusions: HCV testing solely based on presence of risk factors in non-Birth Cohort patients has the potential to miss a significant number of HCV antibody positive patients. Given patient- and provider-level barriers in elucidating risk factors, universal HCV antibody screening may be warranted.
