Role of the nurse practitioner in the management of patients with chronic hepatitis C

Effects of Health Insurance Among Patients on Hepatitis C Treatment Along the Texas-Mexico Border

The incidence and prevalence of hepatitis C virus (HCV) is steadily increasing across the world. Increasing morbidity and mortality rates associated with HCV are influencing research on treatment outcomes. The purpose of this project was to examine the effect of health insurance status and office visit compliance on sustained virologic response (SVR) in adult patients living along the Texas-Mexico border treated for HCV and who received dual or triple medication therapy between January 2010 and August 2013. The objective of this project was to determine whether there is an association between health insurance status, and/or office visit compliance, and SVR. We conducted a longitudinal retrospective chart review pilot study of patients who underwent treatment with dual and triple therapy in a border community in Texas. Results revealed that lack of insurance did not affect SVR in the Texas Tech University Health Sciences Center El Paso-based clinic setting due to enrollment into a managed healthcare program. Providing a financial benefit may improve treatment compliance of HCV-infected individuals, reduce overall cost, and improve the patient's quality of life.

Expanding capacity for hepatitis C treatment in the United States: team-based care and use of nonphysician providers

Hepatitis C treatment is rapidly evolving with significant improvements in patient outcomes. With an estimated prevalence of over 3 million persons living with chronic hepatitis C in the United States, it is anticipated that there will be an increase in the number of persons seeking care and treatment for chronic hepatitis C infection. Current systems of care may be overburdened with people seeking care for chronic hepatitis C virus (HCV). Interprofessional models of care have been shown to be feasible and effective in treating different populations affected by chronic HCV. Use of interprofessional teams, integrated models of care, and greater use of nonphysician providers offer a potential solution for expanding capacity to comprehensive HCV treatment and care in the United States.

Impact of provider type on hepatitis C outcomes with boceprevir-based and telaprevir-based regimens

GOALS

To examine the effect of provider type on outcomes and safety in a large hepatitis C virus (HCV)-infected cohort treated in routine medical practice.

BACKGROUND

Nonphysician providers (NPP) are uniquely positioned to expand health care infrastructure to meet HCV treatment demands.

STUDY

Retrospective, observational cohort analysis of 820 HCV genotype 1-infected veterans initiated on peginterferon/ribavirin and boceprevir or telaprevir in routine medical practice at 94 VA facilities before January 1, 2012 and followed through July 30, 2013. Provider type was determined from prescription records and included physicians (MD) or NPPs (ie, nurse practitioners, physician assistants, and pharmacists). Inverse probability-of-treatment weighting and unweighted logistic regression analysis was used for comparison of sustained virologic response (SVR), treatment discontinuation rates, and adverse hematologic events.

RESULTS

There was no significant difference in SVR by provider type overall (NPPs 52% vs. MDs 49%, P=0.33) and within patient subgroups, or in treatment discontinuation rates. In multivariate analyses, provider type was not associated with any significant difference in the odds of achieving SVR (NPP vs. MD; odds ratio 1.17; 95% confidence interval, 0.84-1.63; P=0.37 inverse probability of treatment weighting; odds ration 1.16, 95% confidence interval, 0.84-1.59, P=0.38 unweighted). Hematologic adverse event rates were similar: anemia: 57% NPP, 62% MD; thrombocytopenia: 43% NPP, 40% MD; neutropenia: 40% NPP, 39% MD.

CONCLUSIONS

Treatment prescribed by NPPs was as likely to result in SVR as treatment prescribed by MDs, even after accounting for patient differences. Engaging more NPPs as HCV treatment providers may allow wider access to HCV treatment.

Raising public awareness of hepatitis B and C through a testing road show

Over the past decade, as the profile of hepatitis B and C has been raised, a range of nurse-led services has been developed among substance misuse services, prisons and homeless services to reach those at the highest risk of infection. In the UK, it is estimated that up to two-thirds of people with hepatitis C are unaware of their infection (Cornberg et al, 2011). These patients represent those at the highest risk of developing cirrhosis and liver cancer, and many are unlikely to be in contact with services that offer routine testing. To help address this, the Welsh Hepatitis Nurse Forum (WHNF) carried out two road shows aimed at raising awareness of hepatitis B and C among the general public and offering testing. This paper describes the process, results and evaluation of the road shows that took place in 2011 and 2012. The road show is a unique way in which nurses can reach those who may not have regular contact with health services, and has proved useful for generally raising awareness. Further work is needed to evaluate the cost-effectiveness of the road shows.

Efficacy of pegylated interferon α-2b and ribavirin in chronic hepatitis C virus (genotypes 1 and 4) infection

BACKGROUND AND OBJECTIVE

The course of chronic hepatitis C in children is often mild or asymptomatic, but may lead to liver cirrhosis and neoplasm. The aim of our study was retrospective evaluation of treatment efficacy using pegylated interferon (IFN)-α2b with ribavirin in children and adolescents with chronic hepatitis C, both treatment naïve and re-treated.

METHODS

The study comprised 79 patients with chronic hepatitis C ages 8 to 18 years (43 patients re-treated; 54 infected with genotype 1 hepatitis C virus and 25 with genotype 4), treated with pegylated IFN-α2b (1.5 μg · kg⁻¹ · week⁻¹) plus ribavirin (15 mg · kg⁻¹ · day⁻¹) for 48 weeks. The primary endpoint was sustained virologic response (SVR).

RESULTS

Early viral response (EVR) was observed in 43.1% and end-of-treatment response in 47.9% of patients. In 44.3% of patients, SVR was achieved, which was maintained for at least the next 6 months. Patients not treated before significantly more frequently attained EVR, end-of-treatment response, and SVR (64%, 65.6%, and 63.9%, respectively) as compared with re-treated patients (30%, 33.3%, and 27.9%, respectively). Among 28 patients who attained EVR, 23 achieved SVR. In 2 patients, despite lack of EVR, SVR was observed. There were numerous adverse effects. They were not so severe as to discontinue therapy.

CONCLUSIONS

Combined therapy with pegylated IFN-α2b and ribavirin in patients with chronic hepatitis C, infected with hepatitis C virus genotypes 1 and 4, was more effective in treatment-naïve patients (63.9%) as compared with re-therapy cases (27.9%). SVR was maintained for at least the next 6 months in all of the patients. The applied treatment has limited efficacy and evokes numerous adverse effects; thus, search for new methods of treatment is mandatory.
