Background: Given the paucity of information on dose intensity, the objective of this study is to describe the use of adjuvant chemotherapy for stage III colon cancer, focusing on relative dose intensity (RDI), overall survival (OS) and disease-free survival (DFS).
The impact of viral load suppression, genotype, race, and other factors on the risk of late-stage liver-related events in patients with hepatitis C (HCV) has been assessed previously using data from small observational cohorts or clinical trials. Data from large real-world practice samples are needed to improve risk factor estimates for late-stage liver events and death in HCV.OBJECTIVE To describe the natural history of HCV in real-world clinical practice. DESIGN, SETTING, AND PARTICIPANTS Observational cohort study. Patients with a detectable viral load (>25 IU/mL) and a recorded baseline genotype were selected from the Veterans Affairs (VA) HCV clinical registry (CCR), which compiles electronic medical records data from 1999 to present.EXPOSURES Risk factors included genotype, race, age, sex, and time to achieving an observed undetected viral load.
MAIN OUTCOMES AND MEASURESThe primary outcomes were time to death and time to a composite of liver-related clinical events. Secondary outcomes included the components of the composite clinical outcome. Outcomes were measured using a time-to-event format and were analyzed using Cox proportional hazards models.RESULTS A total of 28 769 of 360 857 unique HCV CCR patients met all study criteria. Only 24.3% of patients received treatment, and 16.4% of treated patients (4.0% of all patients) achieved an undetectable viral load. The unadjusted death rates were 6.8 (95% CI, 6.0-7.7) per 1000 person-years for patients who achieved viral load suppression vs 21.8 (95% CI, 21.5-22.2) deaths per 1000 person-years in patients who did not achieve this goal. Cox model results found that achieving viral suppression reduced risk of the composite clinical end point by 27% (hazard ratio [HR], 0.73 [95% CI, 0.66-0.82]) and the risk of death by 45% (HR, 0.55 [95% CI, 0.47-0.64]). Genotype 2 patients were at significantly lower risk, and genotype 3 patients were at higher risk for all study outcomes relative to genotype 1. Black patients were at lower risk for all liver events than white patients.
CONCLUSION AND RELEVANCEAchieving an undetectable viral load was associated with decreased hepatic morbidity and mortality. It remains to be determined whether newer treatment regimens can offer higher response rates with fewer adverse effects in real-world settings.
This paper describes the Centers of Excellence in Primary Care Education (CoEPCE), a seven-site collaborative project funded by the Office of Academic Affiliations (OAA) within the Veterans Health Administration of the United States Department of Veterans Affairs (VA). The CoEPCE was established to fulfill OAA's vision of large-scale transformation of the clinical learning environment within VA primary care settings. This was accomplished by funding new Centers within VA facilities to develop models of interprofessional education (IPE) to teach health professions trainees to deliver high quality interprofessional team-based primary care to Veterans. Using reports and data collected and maintained by the National Coordinating Center over the first six years of the project, we describe program inputs, the multicomponent intervention, activities undertaken to develop the intervention, and short-term outcomes. The findings have implications for lessons learned that can be considered by others seeking large-scale transformation of education within the clinical workplace and the development of interprofessional clinical learning environments. Within the VA, the CoEPCE has laid the foundation for IPE and collaborative practice, but much work remains to disseminate this work throughout the national VA system.
