Hepatitis C Care in the Department of Veterans Affairs: Building a Foundation for Success

Success of the US Veterans Health Administration's Hepatitis C Virus Care Continuum in the Direct-acting Antiviral Era

BACKGROUND

Estimated hepatitis C prevalence within the Veterans Health Administration is higher than the general population and is a risk factor for advanced liver disease and subsequent complications. We describe the hepatitis C care continuum within the Veterans Health Administration 1 January 2014 to 31 December 2022.

METHODS

We included individuals in Veterans Health Administration care 2021-2022 who were eligible for direct-acting antiviral treatment 1 January 2014 to 31 December 2022. We evaluated the proportion of Veterans who progressed through each step of the hepatitis C care continuum, and identified factors associated with initiating direct-acting antivirals, achieving sustained virologic response, and repeat hepatitis C viremia.

RESULTS

We identified 133 732 Veterans with hepatitis C viremia. Hepatitis C treatment was initiated in 107 134 (80.1%), with sustained virologic response achieved in 98 136 (91.6%). In those who achieved sustained virologic response, 1097 (1.1%) had repeat viremia and 579 (52.8%) were retreated for hepatitis C. Veterans of younger ages were less likely to initiate treatment and achieve sustained virologic response, and more likely to have repeat viremia. Stimulant use and unstable housing were negatively associated with each step of the hepatitis C care continuum.

CONCLUSIONS

The Veterans Health Administration has treated 80% of Veterans with hepatitis C in care 2021-2022 and achieved sustained virologic response in more than 90% of those treated. Repeat viremia is rare and is associated with younger age, unstable housing, opioid use, and stimulant use. Ongoing efforts are needed to reach younger Veterans, and Veterans with unstable housing or substance use disorders.

A cross-sectional survey of viral hepatitis education within pharmacy curricula in the United States

BACKGROUND

The Viral Hepatitis National Strategic Plan emphasizes the importance of a collaborative provider workforce trained in hepatitis prevention and treatment to eliminate viral hepatitis in the United States by 2030. Although pharmacists play a key role in hepatitis management, literature lacks documentation of the amount of viral hepatitis education provided to pharmacy students.

AIM

Our study goal was to describe viral hepatitis education provided at United States pharmacy schools.

METHOD

In this cross-sectional survey study, investigators developed a 19-item Qualtrics questionnaire, sent questionnaire links to curricula content experts at 140 accredited pharmacy colleges/schools in May-June 2022, and allotted 28 days for completion. Questions assessed the viral hepatitis instruction provided to students and hepatitis instructors' training/experience. We used descriptive statistics for analysis.

RESULTS

Forty-eight pharmacy institutions across 29 states/territories responded; 44% had 50-99 students/class, and 58% used lecture and discussion to provide required hepatitis education. Students received more lecture (average = 3.4 h, range 0.8-1.6 h/hepatitis topic) than discussion (average = 1.7 h, range 0.6-0.9 h/hepatitis topic), with the most time spent on hepatitis C, followed by hepatitis B virus. Respondents reported 93% of their instructors had post-graduate training/certifications and 67% worked in clinical settings with hepatitis patients.

CONCLUSION

Survey results demonstrate variability in hepatitis education across United States pharmacy curricula. Data offer stakeholders in hepatitis elimination efforts knowledge about the viral hepatitis education provided to Doctor of Pharmacy students. Future directions include consideration of implementation of minimum hepatitis education standards to further support work toward national hepatitis elimination.

Alcohol Use and Sustained Virologic Response to Hepatitis C Virus Direct-Acting Antiviral Therapy

Importance

Some payers and clinicians require alcohol abstinence to receive direct-acting antiviral (DAA) therapy for chronic hepatitis C virus (HCV) infection.

Objective

To evaluate whether alcohol use at DAA treatment initiation is associated with decreased likelihood of sustained virologic response (SVR).

Design, Setting, and Participants

This retrospective cohort study used electronic health records from the US Department of Veterans Affairs (VA), the largest integrated national health care system that provides unrestricted access to HCV treatment. Participants included all patients born between 1945 and 1965 who were dispensed DAA therapy between January 1, 2014, and June 30, 2018. Data analysis was completed in November 2020 with updated sensitivity analyses performed in 2023.

Exposure

Alcohol use categories were generated using responses to the Alcohol Use Disorders Identification Test-Consumption (AUDIT-C) questionnaire and International Classification of Diseases, Ninth Revision and International Statistical Classification of Diseases and Related Health Problems, Tenth Revision diagnoses for alcohol use disorder (AUD): abstinent without history of AUD, abstinent with history of AUD, lower-risk consumption, moderate-risk consumption, and high-risk consumption or AUD.

Main Outcomes and Measures

The primary outcome was SVR, which was defined as undetectable HCV RNA for 12 weeks or longer after completion of DAA therapy. Multivariable logistic regression was used to estimate odds ratios (ORs) and 95% CIs of SVR associated with alcohol category.

Results

Among 69 229 patients who initiated DAA therapy (mean [SD] age, 62.6 [4.5] years; 67 150 men [97.0%]; 34 655 non-Hispanic White individuals [50.1%]; 28 094 non-Hispanic Black individuals [40.6%]; 58 477 individuals [84.5%] with HCV genotype 1), 65 355 (94.4%) achieved SVR. A total of 32 290 individuals (46.6%) were abstinent without AUD, 9192 (13.3%) were abstinent with AUD, 13 415 (19.4%) had lower-risk consumption, 3117 (4.5%) had moderate-risk consumption, and 11 215 (16.2%) had high-risk consumption or AUD. After adjustment for potential confounding variables, there was no difference in SVR across alcohol use categories, even for patients with high-risk consumption or AUD (OR, 0.95; 95% CI, 0.85-1.07). There was no evidence of interaction by stage of hepatic fibrosis measured by fibrosis-4 score (P for interaction = .30).

Conclusions and Relevance

In this cohort study, alcohol use and AUD were not associated with lower odds of SVR. Restricting access to DAA therapy according to alcohol use creates an unnecessary barrier to patients and challenges HCV elimination goals.

Hepatitis C care cascade in a large academic healthcare system, 2012 to 2018

To determine the hepatitis C virus (HCV) care cascade among persons who were born during 1945 to 1965 and received outpatient care on or after January 2014 at a large academic healthcare system. Deidentified electronic health record data in an existing research database were analyzed for this study. Laboratory test results for HCV antibody and HCV ribonucleic acid (RNA) indicated seropositivity and confirmatory testing. HCV genotyping was used as a proxy for linkage to care. A direct-acting antiviral (DAA) prescription indicated treatment initiation, an undetectable HCV RNA at least 20 weeks after initiation of antiviral treatment indicated a sustained virologic response. Of the 121,807 patients in the 1945 to 1965 birth cohort who received outpatient care between January 1, 2014 and June 30, 2017, 3399 (3%) patients were screened for HCV; 540 (16%) were seropositive. Among the seropositive, 442 (82%) had detectable HCV RNA, 68 (13%) had undetectable HCV RNA, and 30 (6%) lacked HCV RNA testing. Of the 442 viremic patients, 237 (54%) were linked to care, 65 (15%) initiated DAA treatment, and 32 (7%) achieved sustained virologic response. While only 3% were screened for HCV, the seroprevalence was high in the screened sample. Despite the established safety and efficacy of DAAs, only 15% initiated treatment during the study period. To achieve HCV elimination, improved HCV screening and linkage to HCV care and DAA treatment are needed.

Treating Hepatitis C in Individuals With Previous Incarceration: The Veterans Health Administration, 2012-2019

To determine whether the Veterans Health Administration's (VHA) hepatitis C (HCV) treatment campaign reached marginalized populations, we compared HCV care by previous incarceration status with Veterans Aging Cohort Study data. Of those with and those without previous incarceration, respectively, 40% and 21% had detectable HCV, 59% and 65% underwent treatment (P = .07); 92% and 94% of those who completed treatment achieved sustained virologic response. The VHA HCV treatment effort was successful and other systems should replicate those efforts. (Am J Public Health. 2023;113(2):162-165. https://doi.org/10.2105/AJPH.2022.307152).

User experience of a hepatitis c population management dashboard in the Department of Veterans Affairs

BACKGROUND

The Veterans Health Administration (VA) is the largest integrated healthcare organization in the US and cares for the largest cohort of individuals with hepatitis C (HCV). A national HCV population management dashboard enabled rapid identification and treatment uptake with direct acting antiviral agents across VA hospitals. We describe the HCV dashboard (HCVDB) and evaluate its use and user experience.

METHODS

A user-centered design approach created the HCVDB to include reports based on the HCV care continuum: 1) 1945-1965 birth cohort high-risk screening, 2) linkage to care and treatment of chronic HCV, 3) treatment monitoring, 4) post-treatment to confirm cure (i.e., sustained virologic response), and 5) special populations of unstably housed Veterans. We evaluated frequency of usage and user experience with the System Usability Score (SUS) and Unified Theory of Acceptance and Use of Technology 2 (UTAUT2) instruments.

RESULTS

Between November 2016 and July 2021, 1302 unique users accessed the HCVDB a total of 163,836 times. The linkage report was used most frequently (71%), followed by screening (13%), sustained virologic response (11%), on-treatment (4%), and special populations (<1%). Based on user feedback (n = 105), the mean SUS score was 73±16, indicating a good user experience. Overall acceptability was high with the following UTAUT2 rated from highest to least: Price Value, Performance Expectancy, Social Influence, and Facilitating Conditions.

CONCLUSIONS

The HCVDB had rapid and widespread uptake, met provider needs, and scored highly on user experience measures. Collaboration between clinicians, clinical informatics, and population health experts was essential for dashboard design and sustained use. Population health management tools have the potential for large-scale impacts on care timeliness and efficiency.

Association Between Electronic Health Record Time and Quality of Care Metrics in Primary Care

IMPORTANCE

Physicians across the US spend substantial time working in the electronic health record (EHR), with primary care physicians (PCPs) spending the most time. The association between EHR time and ambulatory care quality outcomes is unclear.

OBJECTIVE

To characterize measures of EHR use and ambulatory care quality performance among PCPs.

DESIGN, SETTING, AND PARTICIPANTS

A cross-sectional study of PCPs with longitudinal patient panels using a single EHR vendor was conducted at Brigham and Women's Hospital and Massachusetts General Hospital during calendar year 2021.

EXPOSURES

Independent variables included PCPs demographic and practice characteristics and EHR time measures (PCP-level mean of daily total EHR time, after-hours time, time from 5:30 pm to 7:00 am and time on weekends, and daily EHR time on notes, sending and receiving patient, staff, results, prescription, or system messages [in-basket], and clinical review).

MAIN OUTCOMES AND MEASURES

Outcome variables were ambulatory quality measures (year-end, PCP panel-level achievement of targets for hemoglobin A1c level control, lipid management, hypertension control, diabetes screening, and breast cancer screening).

RESULTS

The sample included 291 physicians (174 [59.8%] women). Median panel size was 829 (IQR, 476-1157) patients and mean (SD) clinical full-time equivalent was 0.54 (0.27). The PCPs spent a mean (SD) of 145.9 (64.6) daily minutes on the EHR. There were significant associations between EHR time and panel-level achievement of hemoglobin A1c control, hypertension control, and breast cancer screening targets. In adjusted analyses, each additional 15 minutes of total daily EHR time was associated with 0.58 (95% CI, 0.32-0.84) percentage point greater panel-level hemoglobin A1c control, 0.52 (95% CI, 0.33-0.71) percentage point greater hypertension control, and 0.28 (95% CI, 0.05-0.52) higher breast cancer screening rates. Each daily additional 15 minutes of in-basket time was associated with 2.26 (95% CI, 1.05-3.48) greater panel-wide hemoglobin A1c control, 1.65 (95% CI, 0.83-2.47) percentage point greater hypertension control, and 1.26 (95% CI, 0.51-2.02) percentage point higher breast cancer screening rates. Associations were largely concentrated among PCPs with 0.5 clinical full-time equivalent or less. There were no associations between EHR use metrics and diabetes screening or lipid management in patients with cardiovascular disease.

CONCLUSIONS AND RELEVANCE

This cross-sectional study found an association between EHR time and some measures of ambulatory care quality. Although increased EHR time is associated with burnout, it may represent a level of thoroughness or communication that enhances certain outcomes. It may be useful for future studies to characterize payment models, workflows, and technologies that enable high-quality ambulatory care delivery while minimizing EHR burden.

Cost-effectiveness of direct-acting antivirals for chronic hepatitis C virus in the United States from a payer perspective

BACKGROUND: Direct-acting antivirals (DAAs) have been a breakthrough therapeutic innovation in the treatment of chronic hepatitis C virus (HCV) with significantly improved efficacy, safety, and tolerability. OBJECTIVE: To evaluate the cost-effectiveness of treating patients with HCV with DAAs compared with pre-DAAs or no treatment over a lifetime horizon from the perspective of the US Veterans Affairs (VA) health care system. METHODS: A hybrid decision-tree and Markov model simulated the health outcomes of a cohort of 142,147 patients with HCV with an average age of 63 years. Demographic data, treatment rates and distribution, treatment efficacy by subpopulation, and health state costs were sourced from VA data. Treatment costs and utility values were sourced from publicly available databases and prior publications for older regimens. RESULTS: Over a lifetime horizon, the use of DAAs results in a significant reduction in advanced liver disease events compared with pre-DAA and no treatment. Total cost savings of $7 and $9 billion over a lifetime horizon (50 years) were predicted for patients who received DAA treatments compared with patients treated with pre-DAA treatments and those who were untreated, respectively. Cost savings were achieved quickly after treatment, with DAAs being inexpensive when compared with both the pre-DAA and untreated scenarios within 5 years. The DAA intervention dominated (ie, more effective and less costly) for both the pre-DAA and untreated strategies on both a per-patient and cohort basis. CONCLUSIONS: The use of DAA-based treatments in patients with HCV in the VA system significantly reduced long-term HCV-related morbidity and mortality, while providing cost savings within only 5 years of treatment.

Using the Electronic Health Record to Characterize the Hepatitis C Virus Care Cascade

OBJECTIVES

Chronic hepatitis C virus (HCV) infection is one of the main causes of hepatocellular carcinoma. Before initiating a multilevel HCV screening intervention, we sought to (1) describe concordance between the electronic health record (EHR) data warehouse and manual medical record review in recording aspects of HCV testing and treatment and (2) estimate the percentage of patients with chronic HCV infection who initiated and completed HCV treatment using manual medical record review.

METHODS

We examined the medical records for 177 patients (100 randomly selected patients born during 1945-1965 without evidence of HCV testing and 77 adult patients of any birth cohort who had completed HCV testing) with a primary care or relevant specialist visit at an academic health care system in Tampa, Florida, from 2015 through 2018. We used the Cohen κ coefficient to examine the degree of concordance between the searchable data warehouse and the medical record review abstractions. Descriptive statistics characterized referral to and receipt of treatment among patients with chronic HCV infection from medical record review.

RESULTS

We found generally good concordance between the data warehouse abstraction and medical record review for HCV testing data (κ ranged from 0.66 to 0.87). However, the data warehouse failed to capture data on HCV treatment variables. According to medical record review, 28 patients had chronic HCV infection; 16 patients were prescribed treatment, 14 initiated treatment, and 9 achieved and had a reported posttreatment undetected HCV viral load.

CONCLUSIONS

Using data warehouse data provides generally reliable HCV testing information. However, without the use of natural language processing and purposeful EHR design, manual medical record reviews will likely be required to characterize treatment initiation and completion.

Prevalence and Characteristics of Chronic Hepatitis C Among Asian Americans Are Distinct From Other Ethnic Groups

GOAL

The goal of this study was to determine the prevalence and characteristics of chronic hepatitis C (CHC) among Asian Americans compared with other ethnicities.

BACKGROUND

Chronic hepatitis C virus (HCV) affects an estimated 2.7 million in the United States, but there are limited data on HCV among Asian Americans.

STUDY

A total of 3,369,881 adults over the age of 18 who were patients of the integrated health care system in Southern California and 4903 Asian participants at community hepatitis screenings were included in a cross-sectional study. Variables included HCV serology, HCV genotype, comorbidities, and coinfections.

RESULTS

The prevalence of CHC was 1.3% in the general population (8271 adults) and 0.6% among Asians. The prevalence of CHC was significantly higher in the 1945-1965 birth cohort with 2.7% (5876) in the general population and 1.0% (313) among Asians (P<0.001). Asians had the highest rates of hepatitis B coinfection (2.9% vs. 0.2%, P<0.001). The distribution of genotypes among Asians differed from the general population with the most common genotype being 1b (27.5%) and a higher presence of genotype 6 (9.5%) (P<0.001). The presence of cirrhosis was 17.6% in Asians. Disaggregated Asian data showed that CHC was highest among Vietnamese and Cambodian and that genotype 6 was predominant among these 2 subgroups.

CONCLUSIONS

The prevalence of chronic HCV was significantly lower in Asians compared with other ethnicities. However, disaggregated data among Asians showed the highest prevalence rates among adults from Vietnam and Cambodia.

You Can't Have One Without the Other: Innovation and Ethical Dilemmas in Gastroenterology and Hepatology

Medical innovation and ethical dilemmas are intertwined in gastroenterology and hepatology. This narrative review explores direct-acting antiviral (DAA) therapy for hepatitis C virus (HCV) as a touchstone example of how medical innovation breeds ethical dilemmas. A few quandaries-informed consent as well as informed deferral during the first wave of DAA approvals, sobriety restrictions from payors, and high DAA costs for patients-are addressed through the lens of the foundational principles of clinical medical ethics: autonomy, beneficence, non-maleficence, justice, and utility. By placing these issues within a medical ethics framework, we hope not only to focus on the solutions that the gastroenterology and hepatology community developed in the advent of DAA therapy, but to highlight an ethical paradigm that can be applied to similar dilemmas that will be faced as new therapies for other gastrointestinal diseases are approved.

Strategies to Improve Delivery of Cirrhosis Care

Purpose of review

This review provides an overview of the current state of research around improving healthcare delivery for patients with cirrhosis in the outpatient, inpatient, and transitional care settings.

Recent findings

Recent studies have broadly employed changes to the model of care delivery, team composition, and technology to improve cirrhosis care. In the outpatient setting, approaches have included engaging caregivers, patient navigators, and non-physicians and using virtual care, smartphone applications, and wearables. Inpatient care approaches have focused on the role of interdisciplinary teams, education interventions, and changes to the medical record system, while post-discharge interventions have included day hospitals and care coordinator interventions. This review also describes the Veterans Health Administration’s novel, population-level approach to delivery of cirrhosis care, and addressed how the pandemic has impacted the delivery of cirrhosis care.

Summary

Comprehensive, evidence-based approaches to delivering high-quality cirrhosis care continue to evolve to meet the needs of a growing population in an ever-changing healthcare environment.

The Hepatic Innovation Team Collaborative: A Successful Population-Based Approach to Hepatocellular Carcinoma Surveillance

Simple Summary

Liver cancer is a growing problem that largely impacts people with cirrhosis. This article describes the Veterans Health Administration’s national cirrhosis quality improvement program and its focus on early detection of liver cancer.

Abstract

After implementing a successful hepatitis C elimination program, the Veterans Health Administration’s (VHA) Hepatic Innovation Team (HIT) Collaborative pivoted to focus on improving cirrhosis care. This national program developed teams of providers across the country and engaged them in using systems redesign methods and population health approaches to improve care. The HIT Collaborative developed an Advanced Liver Disease (ALD) Dashboard to identify Veterans with cirrhosis who were due for surveillance for hepatocellular carcinoma (HCC) and other liver care, promoted the use of an HCC Clinical Reminder in the electronic health record, and provided training and networking opportunities. This evaluation aimed to describe the VHA’s approach to improving cirrhosis care and identify the facility factors and HIT activities associated with HCC surveillance rates, using a quasi-experimental design. Across all VHA facilities, as the HIT focused on cirrhosis between 2018–2019, HCC surveillance rates increased from 46% (IQR 37–53%) to 51% (IQR 42–60%, p < 0.001). The median HCC surveillance rate was 57% in facilities with high ALD Dashboard utilization compared with 45% in facilities with lower utilization (p < 0.001) and 58% in facilities using the HCC Clinical Reminder compared with 47% in facilities not using this tool (p < 0.001) in FY19. Increased use of the ALD Dashboard and adoption of the HCC Clinical Reminder were independently, significantly associated with HCC surveillance rates in multivariate models, controlling for other facility characteristics. In conclusion, the VHA’s HIT Collaborative is a national healthcare initiative associated with significant improvement in HCC surveillance rates.

Innovations in Hepatitis C Screening and Treatment

New therapies offer hope for a cure to millions of persons living with hepatitis C virus (HCV) infection. HCV elimination is a global goal that will be difficult to achieve using the traditional paradigms of diagnosis and care. The current standard has evolved toward universal HCV screening and treatment, to achieve elimination goals. There are several steps between HCV diagnosis and cure with major barriers along the way. Innovative models of care can address barriers to better serve hardly reached populations and scale national efforts in the United States and abroad. Herein, we highlight innovative models of HCV care that aid in our progress toward HCV elimination.

Rates and Predictors of Undergoing Different Hepatocellular Carcinoma Screening Tests in Patients With Cirrhosis

INTRODUCTION

We aimed to assess rates and predictors of hepatocellular carcinoma (HCC) screening among patients with cirrhosis.

METHODS

We reviewed electronic health records of 11,361 patients with cirrhosis from 11 U.S. Veterans Health Administration facilities for receipt of HCC screening in the 6 months preceding October 1, 2019.

RESULTS

Nearly half of the cohort (46%) received HCC screening over a 6-month period. Screening rates and modalities (ultrasound, computed tomography, magnetic resonance imaging, serum alpha fetoprotein) varied by facility. Screening was associated with race/ethnicity, body mass index ≥ 25, cirrhosis etiology, thrombocytopenia, Fibrosis-4 ≥ 3.25, and lower Model for End-Stage Liver Disease-Sodium.

DISCUSSION

HCC screening rates varied by facility. Higher risk patients were more likely to receive screening.

Optimizing Hepatitis C Virus (HCV) Treatment in a US Colocated HCV/Opioid Agonist Therapy Program

Background

A minority of patients with opioid use disorder are treated for hepatitis C virus infection (HCV). While colocated HCV and opioid agonist therapy (OAT) along with harm reduction can facilitate prevention and cascade to cure, there are few real-world examples of such embedded care models in the United States in the direct-acting antiviral (DAA) era.

Methods

We conducted a retrospective chart review to determine sustained virologic response (SVR) and reinfection rates during the first 5-year period of DAA availability among individuals tested and treated on-site at Rhode Island’s only nonprofit methadone maintenance program.

Results

Of 275 who initiated DAAs, the mean age (range) was 43 (22–71) years, 34.5% were female, 57.5% had genotype 1a, 23.3% had cirrhosis, and 92% were Medicaid recipients. SVR was 85.0% (232/273), while modified intent-to-treat SVR was 93.2% (232/249); 17 patients did not achieve SVR, 2 awaited SVR 12 weeks post-end-of-treatment, and 24 were lost to follow-up. Thirty reinfections were identified over 375.5 person-years of follow-up (rate, 7.99/100 person-years). The median time to first reinfection (interquartile range) was 128 (85.25–202.5) days. Before July 1, 2018, 72 patients accessed DAAs over 3.7 years; after Medicaid DAA restrictions were lifted, 109 patients accessed DAAs over 1.3 years. The Prior Authorization (PA) process requires many steps, differing across 11 RI insurers, taking 45–120 minutes per patient.

Conclusions

DAA treatment was effective among a marginalized population in an urban colocated OAT/HCV program. Removing DAA restrictions facilitates treatment initiation. The PA process remains a modifiable barrier to expanding capacity in the United States.

Strategy Configurations Directly Linked to Higher Hepatitis C Virus Treatment Starts: An Applied Use of Configurational Comparative Methods

BACKGROUND

The Department of Veterans Affairs (VA) cares for more patients with hepatitis C virus (HCV) than any other US health care system. We tracked the implementation strategies that VA sites used to implement highly effective new treatments for HCV with the aim of uncovering how combinations of implementation strategies influenced the uptake of the HCV treatment innovation. We applied Configurational Comparative Methods (CCMs) to uncover causal dependencies and identify difference-making strategy configurations, and to distinguish higher from lower HCV treating sites.

METHODS

We surveyed providers to assess VA sites' use of 73 implementation strategies to promote HCV treatment in the fiscal year 2015. CCMs were used to identify strategy configurations that uniquely distinguished higher HCV from lower HCV treating sites.

RESULTS

From the 73 possible implementation strategies, CCMs identified 5 distinct strategy configurations, or "solution paths." These were comprised of 10 individual strategies that collectively explained 80% of the sites with higher HCV treatment starts with 100% consistency. Using any one of the following 5 solution paths was sufficient to produce higher treatment starts: (1) technical assistance; (2) engaging in a learning collaborative AND designating leaders; (3) site visits AND outreach to patients to promote uptake and adherence; (4) developing resource sharing agreements AND an implementation blueprint; OR (5) creating new clinical teams AND sharing quality improvement knowledge with other sites AND engaging patients. There was equifinality in that the presence of any one of the 5 solution paths was sufficient for higher treatment starts.

CONCLUSIONS

Five strategy configurations distinguished higher HCV from lower HCV treating sites with 100% consistency. CCMs represent a methodological advancement that can help inform high-yield implementation strategy selection and increase the efficiency and effectiveness of future implementation efforts.

Hepatitis C Virus Screening and Care: Complexity of Implementation in Primary Care Practices Serving Disadvantaged Populations

BACKGROUND

Hepatitis C virus (HCV) disproportionately affects disadvantaged communities.

OBJECTIVE

To examine processes and outcomes of Screen, Treat, Or Prevent Hepatocellular Carcinoma (STOP HCC), a multicomponent intervention for HCV screening and care in safety-net primary care practices.

DESIGN

Mixed-methods retrospective analysis.

SETTING

5 federally qualified health centers (FQHCs) and 1 family medicine residency program serving low-income communities in diverse locations with largely Hispanic populations.

PATIENTS

Persons born in 1945 through 1965 (baby boomers) who had never been tested for HCV and were followed through May 2018.

INTERVENTION

The Reach, Effectiveness, Adoption, Implementation, and Maintenance (RE-AIM) model guided implementation and evaluation. Test costs were covered for uninsured patients.

MEASUREMENTS

All practices tested patients for anti-HCV antibody (anti-HCV) and HCV RNA. For uninsured patients with chronic HCV in 4 practices, quantitative data also enabled assessment of HCV staging, specialist teleconsultation, direct-acting antiviral (DAA) treatment, and sustained virologic response (SVR). Implementation fidelity and adaptation were assessed qualitatively.

RESULTS

Anti-HCV screening was done in 13 334 of 27 700 baby boomers (48.1%, varying by practice from 19.8% to 71.3%). Of 695 anti-HCV-positive patients, HCV RNA was tested in 520 (74.8%; 48.9% to 92.9% by practice), and 349 persons (2.6% of those screened) were diagnosed with chronic HCV. In 4 FQHCs, 174 (84.9%) of 205 uninsured patients with chronic HCV had disease staging, 145 (70.7%) had teleconsultation review, 119 (58.0%) were recommended to start DAA therapy, 82 (40.0%) initiated free DAA therapy, 74 (36.1%) completed therapy (27.8% to 60.0% by practice), and 70 (94.6% of DAA completers) achieved SVR. Implementation was promoted by multilevel practice engagement, patient navigation, and anti-HCV screening with reflex HCV RNA testing.

LIMITATION

No control practices were included, and data were missing for some variables.

CONCLUSION

Despite a similar framework for STOP HCC implementation, performance varied widely across safety-net practices, which may reflect practice engagement as well as infrastructure or cost challenges beyond practice control.

Access to Comprehensive Services for Advanced Liver Disease in the Veterans Health Administration

BACKGROUND

The Veterans Health Administration (VHA) provides care to the one of the largest cohorts of patients with advanced liver disease (ALD) in the USA.

AIMS

We performed a national survey to assess system-wide strengths and barriers to care for Veterans with ALD in this national integrated healthcare setting.

METHODS

A 52-item survey was developed to assess access and barriers to care in Veterans with ALD. The survey was distributed to all VHA medical centers in 2015. Results were analyzed using descriptive statistics.

RESULTS

One hundred and fifty-three sites responded to this survey. Multidisciplinary services were available on-site at > 80% of sites. Ninety-five percent of sites had mental health and addictions treatment available, with 14% co-locating these services within the liver clinic. Few sites (< 25%) provided pharmacologic treatment for alcohol use disorder in primary care or hepatology settings. Seventy-two percent of sites reported at least one barrier to liver-related care. Of the sites reporting at least one barrier, 53% reported barriers to liver transplant referral, citing complex processes and lack of staff/resources to coordinate referrals. Palliative care was widely available, but 61% of sites reported referring < 25% of their patients with ALD for palliative services.

CONCLUSION

Multidisciplinary services for Veterans with ALD are widely available at VHA sites, though barriers to optimal care remain. Opportunities for improvement include the expansion of providers with hepatology expertise, integrating pharmacotherapy for alcohol use disorder into hepatology and primary care, streamlining the transplant referral process, and expanding palliative care referrals for patients with ALD.

A Path to Ending Hepatitis C in Ethiopia: A Phased Public Health Approach to Achieve Micro-Elimination

Ethiopia's hepatitis C virus (HCV) prevalence is predicted to rise by 2030. To halt this increasing trend, a suitable approach to the elimination of HCV is needed. This review explores the current status, challenges, and opportunities and outlines a strategy for the micro-elimination approach in Ethiopia. I searched PubMed and EMBASE using combined Medical Subject Heading databases for the literature on HCV micro-elimination. A phased public health approach to HCV micro-elimination, including preparation/capacity building (phase I), implementation (phase II), and rollout and scale-up (phase III), targeting people living with HIV, prisoners, chronic hepatitis and cancer patients, blood donors, and pregnant women is a pragmatic strategy to Ethiopia. This can be implemented at general and tertiary care referral hospitals with a future scale-up to district hospitals through task-shifting by training general practitioners, nurses, laboratory technologists, and pharmacists. Availability of the highly effective direct-acting antivirals (DAAs) can be ensured by expanding the existing program that provides highly subsidized DAAs through an agreement with Gilead Sciences, Inc. and eventually aiming at domestic generic manufacturing. The significant enablers to HCV micro-elimination in Ethiopia include the control of healthcare-associated HCV infection, blood safety, access to affordable testing and pan-genotypic DAAs, task-shifting, multisectoral partnership, and regulatory support. General population-based HCV screening and treatment are not cost-effective for Ethiopia because of high cost, program complexity, and disease epidemiology.

Expanding Hepatitis C Virus Care and Cure: National Experience Using a Clinical Pharmacist-Driven Model

Background

The US National Viral Hepatitis Action Plan depends on additional providers to expand hepatitis C virus (HCV) treatment capacity in order to achieve elimination goals. Clinical pharmacists manage treatment and medication within interdisciplinary teams. The study’s objective was to determine sustained virologic response (SVR) rates for clinical pharmacist–delivered HCV therapy in an open medical system.

Methods

Investigators conducted a multicenter retrospective cohort study of patients initiating direct-acting antivirals from January 1, 2014, through March 12, 2018. Data included demographics, comorbidities, treatment, and clinical outcomes. The primary outcome of SVR was determined for patients initiating (intent-to-treat) and those who completed (per-protocol) treatment. Chi-square tests were conducted to identify associations between SVR and adverse reactions, drug–drug interactions, and adherence.

Results

A total of 1253 patients initiated treatment; 95 were lost to follow-up, and 24 discontinued therapy. SVR rates were 95.1% (1079/1134) per protocol and 86.1% (1079/1253) intent to treat. The mean age (SD) was 57.4 (10.1) years, the mean body mass index (SD) was 28.7 (6.2) kg/m², 63.9% were male, 53.7% were black, 40.3% were cirrhotic, 88.4% were genotype 1, and 81.6% were treatment-naïve. Patients missing ≥1 dose had an SVR of 74.9%; full adherence yielded 90% (P < .0001).

Conclusions

HCV treatment by clinical pharmacists in an open medical system resulted in high SVR rates comparable to real-world studies with specialists and nonspecialists. These findings demonstrate the success of a clinical pharmacist–delivered method for HCV treatment expansion and elimination.

Pharmacist-driven multidisciplinary pretreatment workup process for hepatitis C care: A novel model for same-day pretreatment workup

OBJECTIVES

The objective is to describe and quantify the impact of a novel practice model for pharmacist involvement in care coordination and patient education in hepatitis C virus (HCV) care.

SETTING

This practice model was implemented in the gastroenterology clinic at the Richard L. Roudebush Veterans Affairs Medical Center in Indianapolis, Indiana.

PRACTICE DESCRIPTION

Traditional pretreatment workup for HCV requires multiple on-site appointments to complete imaging and laboratory assessments and for provider and social work appointments. High pretreatment time burden and increasing psychosocial complexity of the patient population present significant barriers to HCV eradication. Patients frequently miss appointments, and each on-site visit creates a separate opportunity for patients to be lost to follow-up.

PRACTICE INNOVATION

The pharmacist-driven multidisciplinary pretreatment workup process was launched by HCV pharmacists to mitigate barriers. Patients complete the pretreatment evaluation process, which includes same-day pharmacy education, provider visit, social work assessment, FibroScan, and laboratory assessments, in approximately 2.5 hours.

EVALUATION

Forty-six patients who completed the pharmacist-driven multidisciplinary pretreatment workup process versus 235 patients who completed traditional workup were analyzed for time from date of HCV consultation placement to treatment start and time from most recent HCV provider visit to treatment start.

RESULTS

From time of HCV consult entry to date of treatment start, patients were initiated on HCV treatment in an average of 42.2 ± 7.5 days and 184.1 ± 27.6 days (P = 0.0001) within the intervention and traditional workup groups, respectively. A decreased time from most recent HCV provider visit to treatment initiation was noted between groups with 38.2 ± 7.1 days and 54.7 ± 3.6 days (P = 0.04) in the intervention and traditional workup groups, respectively.

CONCLUSION

The pharmacist-driven multidisciplinary pretreatment workup process is an effective way to engage patients and decrease time to treatment initiation. This model could be replicated in other practice settings, especially those challenged by multi-step care coordination.

Primary care provider perceptions and experiences of implementing hepatitis C virus birth cohort testing: a qualitative formative evaluation

Background

In 2014, the Department of Veterans Affairs (VA) adopted a screening test policy for hepatitis C virus (HCV) in all “Baby Boomers” - those born between 1945 and 1965. About 1 in 12 Veterans were estimated to be infected with HCV yet approximately 34% of the birth cohort remained untested. Early HCV diagnosis and successful antiviral treatment decrease the risk of onward transmission, cirrhosis, hepatocellular carcinoma, liver transplant, and death. Implementing evidence-based HCV screening in primary care has great potential to reduce morbidity and mortality. To inform design and implementation of a quality improvement intervention, we studied primary care provider (PCP) perceptions of and experiences with HCV birth cohort testing.

Methods

We conducted a formative evaluation using qualitative semi-structured interviews guided by the integrated Promoting Action on Research Implementation in Health Services (i-PARIHS) framework. Twenty-two PCPs in six states across a large integrated US healthcare system were interviewed. Content analysis with a priori and emergent codes was performed on verbatim interview transcripts.

Results

We identified three themes related to primary care provider HCV testing and linkage practices, as mapped to i-PARIHS constructs: 1) evaluating cues to HCV testing (innovation/evidence), 2) framing HCV testing decisions (recipients), and 3) HCV testing and linkage to care in the new treatment era (context). The most frequently reported HCV testing cue was an electronic clinical reminder alert, followed by clinical markers and the presence of behavioral risk factors. Most PCPs saw testing as routine, but less urgent, leading to some reluctance. Providers largely saw themselves as performing guideline-concordant testing, yet no performance data were available to assess performance. Given the recent availability of new HCV medications, many PCPs were highly motivated to test and link patients to specialty care for treatment.

Conclusions

Our results suggest a multi-component intervention around awareness and education, feedback of performance data, clinical reminder updates, and leadership support, would address both a significant need, and be deemed acceptable and feasible to primary care providers.
