Genotype 1 hepatitis C virus and the pharmacist's role in treatment

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.

Outcomes of a Pharmacist-Led Hepatitis C Virus Treatment Program in an Urban Safety-Net Health System, Chicago, 2017-2019

OBJECTIVE

A recommendation in March 2020 to expand hepatitis C virus (HCV) screening to all adults in the United States will likely increase the need for HCV treatment programs and guidance on how to provide this service for diverse populations. We evaluated a pharmacist-led HCV treatment program within a routine screening program in an urban safety-net health system in Chicago, Illinois.

METHODS

We collected data on all patient treatment applications submitted from January 1, 2017, through June 30, 2019, and assessed outcomes of and patient retention in the treatment cascade.

RESULTS

During the study period, 203 HCV treatment applications were submitted for 187 patients (>1 application could be submitted per patient): 49% (n = 91) were aged 55-64, 62% (n = 116) were male, 67% (n = 125) were Black, and 15% (n = 28) were Hispanic. Of the 203 HCV treatment applications, 87% (n = 176) of patients were approved for treatment, 91% (n = 161) of whom completed treatment. Of the 161 patients who completed treatment, 81% (n = 131) attended their sustained virologic response (SVR) follow-up visit, 98% (n = 129) of whom reached SVR. The largest drop in the treatment cascade was the 19% decline from receipt of treatment to SVR follow-up visit.

CONCLUSION

The pharmacist-led model for HCV treatment was effective in navigating patients through the treatment cascade and achieving SVR. Widespread implementation of pharmacist-led HCV treatment models may help to hasten progress toward 2030 HCV elimination goals.

Hepatitis C virus infection and the role of a pharmaceutical care program

PURPOSE

The design, implementation, and assessment of a comprehensive pharmaceutical care program (CPCP) for hepatitis C virus (HCV)-infected patients treated with direct-acting antivirals (DAA) are described.

SUMMARY

The advent of DAA regimens has caused the evolution of the role of hospital pharmacists, leading to the development of more specialized models of pharmaceutical care. Three clinical pharmacists were incorporated into the pharmacy department of a general tertiary teaching hospital in Madrid, Spain, with the aim of developing and implementing a CPCP for HCV-infected patients. Pharmacists were responsible for proposing standards and local guidelines to physicians, monitoring adherence to guidelines, managing drug interactions and adverse drug events (ADEs), providing patient education, and evaluating health outcomes and costs. Implementation steps included (1) estimation of the healthcare demand and pharmacy resources, (2) definition of the workflow of the CPCP, (3) definition of the treatment care plan, for which tools were developed to support pharmaceutical validation, detection, and management of ADEs and drug-drug interactions, and (4) program assessment in terms of safety and cost-effectiveness. The pharmacists' interventions performed, severity of errors intercepted, and patients' satisfaction with the CPCP were also assessed. This CPCP demonstrates that the involvement of the pharmacist throughout the care plan prevents harmful medication errors in this population (0.1 per patient) and prompts significant cost savings (€1.2 million for 1,930 treated patients).

CONCLUSION

The implementation of a CPCP developed by hospital pharmacists for patients treated with DAA for HCV infection is an effective approach for preventing harmful medication errors and improving cost- effectiveness.

Evaluation of human immunodeficiency virus curricular content in schools of pharmacy in the United States

INTRODUCTION

Human immunodeficiency virus (HIV) is an important educational topic for student pharmacists given extended patient life expectancy and expanding pharmacist roles in HIV treatment and prevention. Data are lacking in regard to curricular content and type of training received by faculty to provide didactic and experiential HIV training.

METHODS

A cross-sectional, population-based survey of United States (US) pharmacy schools was conducted using a 15-item questionnaire. HIV content experts were surveyed at 135 four-year, accredited programs.

RESULTS

Thirty-seven responses were received from schools in the Midwestern (34%), Northeastern (26%), Southern (26%), and Western (14%) regions. Time devoted to didactic HIV education ranged from 0.5 to 60 hours. The majority of respondents (78%, n = 29) reported 10 or fewer hours of HIV-related content, with 41% (n = 15) reporting five or less hours of content. Experiential practice sites for HIV training were variable, with a majority (80%) including an outpatient infectious diseases/HIV clinic. Eighty percent of respondents also reported students receiving fewer than 25 encounters with people living with HIV (PLWH) throughout their entire experiential training. Over half (54%) of respondents reported that the primary HIV instructor devoted four hours per week or less to HIV care.

CONCLUSIONS

Diversity in the amount of time devoted to HIV didactic education existed among reporting US pharmacy schools. Few schools have dedicated faculty spending a substantial amount of time in direct care of PLWH. Minimum standards for HIV education in schools of pharmacy should be established.

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.

Treatment Outcomes of Hepatitis C-Infected Patients in Specialty Clinic vs. Primary Care Physician Clinic: A Comparative Analysis

Background

Oral direct-acting antivirals (DAAs) provide an exceptional opportunity to treat hepatitis C virus (HCV) infection.

Goals

We compared the treatment outcomes between specialty and primary care physician (PCP) clinics for patients treated with DAAs.

Methods

We performed a retrospective analysis of patients treated for HCV in our PCP clinics and specialty; liver and gastroenterology clinics and gastroenterology clinics. We used the two-sided t-test and the chi-square test to compare the means of continuous and categorical variables, respectively.

Results

Data from a total of 377 patients was analyzed (PCP clinic: n = 185 and specialty clinic: n = 192). There was no significant difference between age, race, and gender. Model for End-Stage Liver Disease (MELD) and Child-Turcotte-Pugh (CTP) scores were comparable at baseline. Greater than 90% of the patients achieved sustained virological response (SVR) with no difference between the groups.

Conclusions

Uncomplicated patients can be treated for hepatitis C by their PCPs with DAAs with similar treatment outcomes to specialty clinics. There should be explicit guidelines on patient eligibility for treatment by PCPs vs. specialists.

The Evolving Role of Pharmacists in Transgender Health Care

Pharmacists are increasingly part of a multifaceted team providing health care to members of the often marginalized transgender (TG) community. Some pharmacists, however, may feel unprepared to care for and interact with TG individuals. By providing comprehensive, respectful, and gender-affirming support, improving physical pharmacy environments with policies and procedures, pharmacists can be trustworthy providers for TG patients. This review focuses primarily on the health issues of TG persons and the pharmacist's role in promoting health, identifying barriers to health care, and providing health care resources for TG persons. The evolution of psychiatric diagnostic criteria, access to health care, and inclusion of TG, lesbian, gay, and bisexual topics in the educational curriculum are presented. Cultural competency and diversity training that addresses gender identity and sexual orientation issues should be important interdisciplinary and interprofessional activities for all health care professional education programs. Pharmacists play a key role in the health care needs of TG persons that include appropriate laboratory monitoring, complex pharmacotherapeutic challenges, and providing unbiased gender-affirming interactions. The pharmacy's physical environment, staff training, and policies and procedures can offer unique services to TG persons.

The benefits of a public pharmacist service in chronic hepattis C treatment: The real-life results of sofosbuvir-based therapy

BACKGROUND

In Brazil, the sofosbuvir-based therapy was introduced in the public health system (SUS) in 2015 to treat Chronic Hepatitis C (CHC). This drug and other direct-acting antiviral agents (DAAs) represent a major advance in the HCV-infection treatment due to their high effectiveness and tolerability. However, the drug safety profile is limited by significant drug interactions and its use is restricted for their high cost. Pharmacists have the opportunity to improve patient care by monitoring the therapy, recommending strategies to guarantee treatment adherence, effectiveness and safety, preventing complications of the disease, and drug-related problems, thus reducing the cost for patients and payers.

OBJECTIVE

This study aimed to assess the results of the one of the first patient group treated with sofosbuvir in Brazil and their opinions about the benefits of clinical pharmacist services in the achievement of the cure for CHC and in the management of their therapy difficulties.

METHODS

This cohort study (November 2015-January 2017) enrolled 240 patients followed up by the clinical pharmacists at the University Pharmacy (UPh) of the Federal University of Santa Catarina, Brazil, during the CHC treatment. The therapeutic schemes used were sofosbuvir + daclatasvir or + simeprevir associated or not with ribavirin. At the end of the therapy, the patients provided qualitative feedback about the clinical pharmacist services.

RESULTS

The study demonstrated high levels of treatment adherence (99.2% of completion rates) and effectiveness rates (Sustained Virological Response rates) (92.1%). Patients reported high levels of satisfaction with the care provided on account of the good rapport built with their pharmacist, the counseling and education on HCV-infection and on sofosbuvir-based therapy utilization, motivation for adherence, and convenient access to the pharmacist.

CONCLUSIONS

The clinical pharmacist services provided by the UPh was beneficial to patients treated for CHC with the sofosbuvir-based therapy.

Role of a clinical pharmacist as part of a multidisciplinary care team in the treatment of HCV in patients living with HIV/HCV coinfection

Background

The objective of the study was to evaluate the role of a clinical pharmacist in hepatitis C virus (HCV) treatment of patients living with HIV/HCV coinfection.

Methods

We conducted a descriptive study to quantify the functions of a clinical pharmacist in HCV treatment of patients living with HIV/HCV coinfection who were initiating HCV treatment at a publicly funded clinic between March 18, 2015 and September 15, 2016. The clinical pharmacist’s role was categorized into eight categories: 1) HCV prior authorization (PA) completion; 2) HCV medication adherence counseling; 3) HCV drug-drug interaction (DDI) counseling and screening; 4) HCV medication counseling regarding common adverse events (AEs); 5) HCV counseling regarding HCV treatment outcomes and risk of reinfection; 6) ordering laboratory tests and interpretation of HCV laboratory values; 7) HIV medication AE assessment; and 8) other (including refilling medications and management of other comorbidities).

Results

One hundred and thirty-five patients initiated treatment during this timeframe: 77.0% were males, 56.3% non-cirrhotic, 77.0% HCV treatment-naïve, 45.9% HCV genotype 1a, and 83.0% initiated on ledipasvir/sofosbuvir. The clinical pharmacist completed 150 PAs, counseled on HCV medication adherence in 79.2% of patients, conducted HCV DDI counseling and screening in 54.2%, and monitored HCV medication AEs in 54.2%. The clinical pharmacist counseled patients on HCV treatment outcomes and risk of reinfection in 53.1%, ordered laboratory tests in 44.8%, and reported and interpreted laboratory values in 44.8%. The clinical pharmacist assessed HIV medication AEs in 54.2% of patients and participated in other activities in 42.7%.

Conclusion

A clinical pharmacist’s expertise as part of a multidisciplinary care team facilitates optimal treatment outcomes and provides critical support in the management of DAA therapy in individuals living with HIV/HCV coinfection.

Evaluation of pharmaceutical intervention in direct-acting antiviral agents for hepatitis C virus infected patients in an ambulatory setting: a retrospective analysis

Background

Direct-acting antivirals (DAAs) are known to improve tolerability and have higher efficacy and shorter treatment durations compared with conventional interferon (IFN)-based treatments for hepatitis C virus (HCV) infection. Management of drug interactions and maintenance of patient adherence are important to achieve adequate therapeutic effects, sustained virological response (SVR). In order to maximize the benefits of oral DAA therapy, we established an ambulatory care pharmacy practice, a model of integrated collaboration between physicians and pharmacists, for patients receiving IFN-free DAA therapy. In this study, we evaluated pharmaceutical intervention for patients visiting the ambulatory care pharmacy practice.

Methods

HCV-infected outpatients who visited our ambulatory care pharmacy practice between September 2014 and May 2017 were eligible for inclusion in the study. When IFN-free DAAs were first prescribed, the physicians recommended all patients to visit the ambulatory care pharmacy practice after their clinical examination. Subsequently, at the second visit or later, the patients visited the pharmacy service before the physician's examination. The primary endpoint was SVR, defined as HCV RNA below the lower limit of quantification after the completion of treatment. We also evaluated the adherence rate to DAAs, suggestions to the physicians by the pharmacists, and questions from the patients. All data were obtained retrospectively using an electronic medical record system.

Results

Among the 401 study subjects, 386 patients completed the IFN-free DAA therapy. A total of 365 patients have reached 12 or 24 weeks after completing the treatment. The overall SVR rate was 98.1% (358/365). The proportion of patients with adherence ≥90% was 99.3% (398/401). Two-hundred and sixty-seven (84%) among 318 suggestions of prescription made by the pharmacists mainly to manage the adverse events were accepted by the physicians. The pharmacists received and answered 1072 questions on DAA therapy from the patients.

Conclusions

This study indicates that the pharmaceutical intervention may contribute to enhanced adherence to DAAs and higher SVR rates in comparison with previous reports. This study also demonstrates that collaboration between physicians and pharmacists in an ambulatory setting provides favorable outcomes for patients receiving IFN-free DAAs.

Implementation of a New Clinic-Based, Pharmacist-Managed PCSK9 Inhibitor Consultation Service

BACKGROUND

The proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitors alirocumab and evolocumab were approved by the FDA in 2015. In anticipation of provider interest and a potential increase in referrals to the on-site specialty pharmacy, we created a pharmacist-managed consultation service.

PROGRAM DESCRIPTION

The development of a clinic-based pharmacist-managed consultation service for the management of the PCSK9 inhibitor agents alirocumab and evolocumab is described. Key implementation steps included (a) creation of a pharmacy team and collaboration with cardiology; (b) completion of a needs assessment; (c) service creation; (d) collaboration with the on-site specialty pharmacy; (e) development of an electronic consult order and consult pool; (f) personnel training; and (g) service approval and marketing. The service development occurred over 9 months (July 2015-April 2016) and was implemented hospital-wide in May 2016.

OBSERVATIONS

The University of Illinois Hospital and Health Sciences System PCSK9 inhibitor consultation service successfully integrated the benefits of a clinical review process, information technology capabilities of an electronic medical record system, and collaboration with the on-site specialty pharmacy to provide a comprehensive service that aimed to facilitate appropriate medication management from prescribing to patient administration and provide monitoring for this class of specialty medications.

IMPLICATIONS/RECOMMENDATIONS

The PCSK9 pharmacist-managed consultation service provides a method for complex therapies to be managed comprehensively through the collaboration of ambulatory care clinics and outpatient specialty pharmacies.

Outcomes of Pharmacy-Led Hepatitis C Direct-Acting Antiviral Utilization Management at a Veterans Affairs Medical Center

BACKGROUND

The Veterans Affairs Health (VA) Administration has reported hepatitis C virus (HCV) infection rates among veterans to be twice that of the general U.S population. New HCV direct-acting antiviral (DAA) treatment options offer superior sustained virologic response (SVR) rates, improved side-effect profiles, and shortened treatment courses; yet, these new HCV DAAs are expensive, and utilization management strategies are needed to optimize use and improve clinical outcomes. A VA medical center uses pharmacist-led HCV DAA utilization management strategies that includes clinical guidance, optimizing operational flow, budget tracking and forecasting, and patient outcomes tracking.

OBJECTIVE

To assess the economic and clinical outcomes of pharmacy-led HCV DAA utilization management in a VA medical center.

METHODS

This was a single-center, retrospective cohort study. Patient electronic health records and the hepatitis C DAA outcomes tracking database were reviewed at a VA medical center. Patients with an HCV DAA prior authorization drug request and therapy initiated between October 1, 2014, and September 30, 2015, were included. The primary endpoint was the ratio of drug spend to cure rate calculated as the total dollars spent to the number of patients achieving SVR at least 12 weeks from end of treatment. Secondary endpoints included economic, clinical, and safety outcomes.

RESULTS

A total of 372 patients were included in the study. The overall cost ratio of total drug spend to cure rate was $40,135.22. The overall cure rate was 94.1%, with no discontinuations due to treatment failure. The ratio of drug spend to cure rate was $41,907.35 and $38,430.77 in cirrhotic and noncirrhotic patients, respectively, and $39,481.62 and $39,178.74 in treatment-experienced and naive patients, respectively. Ten patients discontinued therapy because of the adverse effects of anemia, nausea, vomiting, and anxiety. The medication possession ratio was 98.7% (± 0.13) for all patients included in the study.

CONCLUSIONS

This study suggests that pharmacist-led HCV DAA utilization management is an important factor in costs and cure rates. Utilization management strategies are valuable to help adequately manage patients with chronic hepatitis C (CHC) and may allow practitioners to maximize available funding for CHC, while maintaining high efficacy and safety.

DISCLOSURES

No outside funding supported this research. The authors have no conflicts of interest to report. Study concept and design were contributed primarily by Britt, along with Hashem, Brown, and Yang. Yang took the lead in data collection, along with Britt, and data interpretation was performed by all the authors. The manuscript was written and revised by Yang, Britt, Brown, and Hashem.

Patient satisfaction with the clinical pharmacist and prescribers during hepatitis C virus management

WHAT IS KNOWN AND OBJECTIVES

Clinical pharmacists play an important role in the management of patients undergoing hepatitis C virus (HCV) treatment. No satisfaction surveys have been published on clinical pharmacist interventions in HCV management. The objective was to evaluate patient satisfaction with clinical pharmacist and prescriber services in the HCV patient population at an urban academic hepatology clinic.

METHODS

An anonymous patient satisfaction survey was offered to patients who were initiating or receiving HCV treatment under the care of a clinical pharmacist. Survey items assessed demographics and satisfaction with HCV care. Satisfaction was assessed with 17 or 20 Likert-scale questions (1 = poor, 2 = fair, 3 = okay, 4 = good, 5 = great) and two or three open-ended questions. Survey results were analysed via comparative and descriptive statistics. A qualitative content analysis was used for the open-ended survey questions.

RESULTS AND DISCUSSION

Sixty-four patients completed 77 (24 pharmacist and 53 prescriber) patient satisfaction surveys. The mean age was 53 (±9·72) years. Patients reported high levels of satisfaction with the pharmacist and prescribers. All 24 (100%) patients ranked overall satisfaction with services provided by pharmacists as 'great', and 36 (69%) of 52 patients ranked overall satisfaction with services provided by prescribers as 'great'. Patients supported the inclusion of a clinical pharmacist on health care teams for other disease states.

WHAT IS NEW AND CONCLUSION

Patients reported high levels of satisfaction with the clinical pharmacist involved in HCV treatment management at an urban academic medical centre. Clinical pharmacist services were highly valued and recommended by the patients surveyed. The survey was able to identify areas in need of improvement in the clinic. Clinical pharmacists play an important role in the treatment and management of HCV. This survey may serve as a model for assessment of satisfaction in other pharmacist-run clinic settings.

How I treat hepatitis C virus infection in patients with hematologic malignancies

Hepatitis C virus (HCV) infection is not uncommon in cancer patients. Over the past 5 years, treatment of chronic HCV infection in patients with hematologic malignancies has evolved rapidly as safe and effective direct-acting antivirals (DAAs) have become the standard-of-care treatment. Today, chronic HCV infection should not prevent a patient from receiving cancer therapy or participating in clinical trials of chemotherapy because most infected patients can achieve virologic cure. Elimination of HCV from infected cancer patients confers virologic, hepatic, and oncologic advantages. Similar to the optimal therapy for HCV-infected patients without cancer, the optimal therapy for HCV-infected patients with cancer is evolving rapidly. The choice of regimens with DAAs should be individualized after thorough assessment for potential hematologic toxic effects and drug-drug interactions. This study presents clinical scenarios of HCV-infected patients with hematologic malignancies, focusing on diagnosis, clinical and laboratory presentations, complications, and DAA therapy. An up-to-date treatment algorithm is presented.
