Longitudinal assessment of liver stiffness by transient elastography for chronic hepatitis C patients.

Background: Liver fibrosis is a common pathway of liver injury and is a feature of most chronic liver diseases. Fibrosis progression varies markedly in patients with hepatitis C virus (HCV). Liver stiffness has been recommended as a parameter of fibrosis progression/regression in patients with HCV.

Rate of sepsis hospitalizations after misdiagnosis in adult emergency department patients: a look-forward analysis with administrative claims data using Symptom-Disease Pair Analysis of Diagnostic Error (SPADE) methodology in an integrated health system.

Objectives: Delays in sepsis diagnosis can increase morbidity and mortality. Previously, we performed a Symptom-Disease Pair Analysis of Diagnostic Error (SPADE) "look-back" analysis to identify symptoms at risk for delayed sepsis diagnosis. We found treat-and-release emergency department (ED) encounters for fluid and electrolyte disorders (FED) and altered mental status (AMS) were associated with downstream sepsis hospitalizations.

Antecedent treat-and-release diagnoses prior to sepsis hospitalization among adult emergency department patients: a look-back analysis employing insurance claims data using Symptom-Disease Pair Analysis of Diagnostic Error (SPADE) methodology.

Objectives: The aim of this study was to identify delays in early pre-sepsis diagnosis in emergency departments (ED) using the Symptom-Disease Pair Analysis of Diagnostic Error (SPADE) approach.

Methods: SPADE methodology was employed using electronic health record and claims data from Kaiser Permanente Mid-Atlantic States (KPMAS). Study cohort included KPMAS members ≥18 years with ≥1 sepsis hospitalization 1/1/2013-12/31/2018.

Beyond the HIV Care Continuum and Viral Suppression: Broadening the Scope of Quality Metrics for Total HIV Patient Care.

Assessing quality care for people with HIV (PWH) should not be limited to reporting on HIV Care Continuum benchmarks, particularly viral suppression rates. At Kaiser Permanente Mid-Atlantic States (KPMAS), an integrated health system providing HIV care in the District of Columbia, Maryland, and Virginia, we created a comprehensive measure of HIV quality care, including both preventative measures and clinical outcomes. We included PWH ≥18 years old with ≥6 months KPMAS membership between 2015 and 2018.

Hepatitis C Care Pathway Associated With Increased Screening, Confirmation, and Diagnosis Communication to Patients.

National policy initiatives and the advent of highly efficacious direct-acting antivirals set the stage to increase the identification and care of patients with hepatitis C virus (HCV). We implemented a multifaceted HCV care pathway, inclusive of automated screening alerts for all patients born between 1945 and 1965 as they are registered for appointments, reflex laboratory orders for positive HCV antibody results, and a care coordinator to facilitate diagnosis communication and engagement in follow-up care. We report the impact of that pathway on HCV screening, confirmation, diagnosis communication, and co-infection screening.

Factors contributing to racial disparities in influenza vaccinations.

Background: Racial/ethnic disparities in rates of influenza vaccinations in the US remain an issue even among those with access, no out-of-pocket costs, and after adjusting for confounders. We used an approach called the Oaxaca-Blinder (OB) decomposition method to ascertain the contribution of covariates individually and in aggregate to the racial disparity in influenza vaccination.

Methods: We included members > = 18 years of age as of 05/01/2014 with continuous enrollment through 04/30/2015.

Impact of Alternative Encounter Types on HIV Viral Suppression Rates in an Integrated Health System.

Kaiser Permanente Mid-Atlantic States (KPMAS) members are increasingly utilizing electronic encounter types, such as telephone appointments and secure messaging for healthcare purposes, although their impact on health outcomes is unknown. We evaluated whether use of alternative encounters by adult human immunodeficiency virus (HIV)-infected patients affected the likelihood of achieving viral suppression (VS). Our study population of 3114 patients contributed 6520 patient-years between 2014 and 2016.

Kidney Function Decline in Patients with CKD and Untreated Hepatitis C Infection.

Background And Objectives: Studies evaluating the role of hepatitis C viral (HCV) infection on the progression of CKD are few and conflicting. Therefore, we evaluated the association of untreated HCV on kidney function decline in patients with stage 3-5 CKD.

Design, Setting, Participants, & Measurements: This retrospective cohort study included members of Kaiser Permanente Southern California and Kaiser Permanente Mid-Atlantic States aged ≥18 years, with incident HCV and CKD diagnoses from January 1, 2004 to December 31, 2014.

Increasing hepatitis C screening in a large integrated health system: science and policy in concert.

Objectives: To evaluate whether the updated 2013 US Preventive Services Task Force (USPSTF) hepatitis C virus (HCV) screening recommendations, related Affordable Care Act provisions, and the impending availability of efficacious therapies were associated with increased screening in an integrated health system.

Study Design: We analyzed 665,339 records of adult patients visiting Kaiser Permanente Mid-Atlantic States clinics from 2003 to 2014.

Methods: We used Cox proportional hazards to estimate time to HCV screening and confirmation after June 1, 2013, compared with prior.

Genome scan for cognitive trait loci of dyslexia: Rapid naming and rapid switching of letters, numbers, and colors.

Dyslexia, or specific reading disability, is a common developmental disorder that affects 5-12% of school-aged children. Dyslexia and its component phenotypes, assessed categorically or quantitatively, have complex genetic bases. The ability to rapidly name letters, numbers, and colors from rows presented visually correlates strongly with reading in multiple languages and is a valid predictor of reading and spelling impairment.
