Outcomes of Treatment for Hepatitis C Virus Infection by Primary Care Providers

Abstract

Background The Extension for Community Healthcare Outcomes (ECHO) model was developed to improve access to care for complex health problems such as hepatitis C virus (HCV) infection for underserved populations. Using videoconferencing technology, ECHO trains primary care providers to treat complex diseases. Methods A prospective cohort study compared treatment of HCV at the University of New Mexico (UNM) HCV clinic to treatment by primary care clinicians at 21 ECHO sites in rural areas and prisons in New Mexico. A total of 407 treatment naive patients with chronic HCV were enrolled. The primary end point was a sustained viral response (SVR). Results The rate of SVR was 57.5% (84/146) for patients treated at UNM and 58.2% (152 /261) at ECHO sites (P=0.89); difference between SVR rates 0.7% (95% CI -9.2%, 10.7%). In genotype 1 infection the SVR rate was 45.8% (38 /83) at UNM and 49.7% (73 /147) at ECHO sites (P=0.57). Serious adverse events occurred in 13.7% of the UNM HCV clinic cohort and 6.9% of the ECHO cohort. Conclusions This study demonstrates that the ECHO model is an effective way to treat HCV in underserved communities. Implementation of this model would allow other states and nations to treat more patients with HCV.

Mixed-Methods Evaluation of a Telehealth Collaborative Care Program for Persons with HIV Infection in a Rural Setting

“…This resembles the Enhancing Community Health Outcomes (ECHO) model for persons with hepatitis C infection in rural New Mexico. 12 We did not pursue this model because our patients stated during early, informal discussions that they preferred to maintain a routine, direct relationship with the HIV specialty clinic via telehealth. This message was repeated in formal interviews with patients in TCC.…”

The Prescribers’ Dilemma: Treatment of Hepatitis C Infection for Medicaid Insured Patients in United States

“…As the number of patients screened for HCV continues to increase, the provider workforce will lack the capacity to provide care for all the newly diagnosed HCV patients in need or wishing to be treated. Limiting DAA to certain prescribers may compromise public efforts to expand access to HCV treatment especially in the rural areas where the primary care clinics as the cornerstone of a "test-and-treat" approach to hepatitis C. 20,21 …”

Training Tomorrow's Comprehensive Primary Care Internists: A Way Forward for Internal Medicine Education

“…Two innovations will be important for managing advanced chronic disease: (1) patient registries, with responsibilities shared across the interprofessional primary care team, 18,19 and (2) decision support by subspecialists, selected and incentivized to promote high-quality care in the comprehensive primary care practice. 20 Tomorrow's comprehensive primary care internist, similar to current family practice physicians, will be able to competently perform common outpatient procedures needed by their patient population (eg, intrauterine device placement, colposcopy, suture of lacerations, incision and drainage of abscesses, joint injection). In some settings, comprehensive internists will provide integrated care by managing their patients in both the inpatient and outpatients arenas.…”
