Pharmacist engagement within a hepatitis C ambulatory care clinic in the era of a treatment revolution

DEA-registered clinical pharmacist practitioners: Progressing practice to increase patient care access

PURPOSE

This descriptive review aims to describe the impact of controlled substance prescriptive authority (CSPA) among Drug Enforcement Administration (DEA)-registered clinical pharmacist practitioners (pharmacists) within the Veterans Health Administration (VA). The practice perspectives of pharmacists with CSPA are also reviewed. A 3-part methodology included identification and query of DEA-registered pharmacists, practice impact data analysis, and time and motion prescribing analysis.

SUMMARY

Between quarter 1 of fiscal year 2018 and quarter 2 of fiscal year 2022, the number of DEA-registered pharmacists in the VA grew by 314%, from 21 to 87 pharmacists. Pharmacists in pain management and mental health reported benefits of CSPA, with the most common being practice autonomy (93%), increased efficiency (92%), and reduced burden on other prescribers (89%). Initial challenges to pharmacists obtaining DEA registration included a lack of incentive (46%) and concern about increased liability (37%). A time and motion analysis demonstrated that pharmacists with CSPA saved a median of 12 minutes for prescription writing compared to those without CSPA.

CONCLUSION

There is an opportunity for DEA-registered pharmacists to meet patient care needs to fill gaps in care from physician shortages, improve health equity, and provide quality healthcare for vulnerable, underserved populations, especially in areas where controlled substance prescribing is common. To fully optimize the role of the pharmacist, it is imperative that state practice acts be expanded to include pharmacist DEA authority as part of collaborative practice and that fair and equitable payment models be established for pharmacist comprehensive medication management.

Interprofessional Collaboration Between a Clinical Pharmacist and Specialty Physicians to Treat Hepatitis C in an Interdisciplinary Medical Practice Setting

Objective: Describes the activities of a clinical pharmacist in a gastroenterology (GI) clinic providing services to hepatitis C virus (HCV) patients, with a focus on practice management activities and tools. Practice Description: Located inside a GI specialty clinic in Fort Worth, Texas, the pharmacist provides comprehensive medication management under a collaborative practice agreement (CPA). Once referred by the GI physician, the pharmacist has face-to-face patient visits, develops the care plan, orders medications, and follows patients through sustained virologic response and the development of a hepatocellular carcinoma surveillance plan. Practice Innovation: The role of pharmacists in the management of HCV is important to understand. This article details a pharmacist-led clinic in an open GI medical practice. Evaluation: A retrospective chart review study was conducted to assess outcomes related to the integration of the clinical pharmacist. Methods: Completed by the study team, this study included manual chart reviews of patients with the ambulatory care pharmacist-driven HCV practice to pull data and information that were then tabulated using Qualtrics. Results: A total of 95 charts were surveyed, 78 records were created, and 49 patients were started on direct-acting antiviral (DAA) treatment by the pharmacist. Patients required multiple pharmacist communication actions. The minimum duration of the pharmacist service was 6 months and could extend more than 9 months depending on the time it took to get the patient started on medication. Pharmacist integration into the practice resulted in improved intake for the GI clinic, improved interprofessional interaction, and increased utilization of newer treatment modalities for HCV which feature cure rates up to 99% with limited side effects. Conclusion: Clinical pharmacists are well positioned to help navigate patients through the complexities of the medication use system, medication access, drug interactions and adverse effects, promote medication adherence, and allow patients to start and complete therapy.

Medication safety in patients with hepatic impairment: A survey of community pharmacists' knowledge level and their practice in caring for these patients

Aims

To study community pharmacists' level of knowledge on medication safety in patients with hepatic impairment and their practice in caring for these patients.

Methods

Pharmacists from Dutch community pharmacies (n = 1545) were invited to participate in an online survey. The survey consisted of 27 questions covering 2 main topics: knowledge and current practice. The level of knowledge was measured by a 6‐item knowledge test. Multiple linear regression was used to identify predictors of correctly answered responses.

Results

In total, 338 pharmacists (22%) completed the questionnaire. The mean knowledge score was 2.8 (standard deviation 1.6). Only 30.3% of respondents were able to appropriately advise on use of analgesics in severe cirrhosis. Postgraduate education on hepatic impairment, knowledge of recently developed practical guidance, and fewer years of practice were associated with a higher level of knowledge. In total, 70.4% indicated to evaluate medication safety in a patient with hepatic impairment at least once weekly. In the past 6 months, 83.3% of respondents consulted a prescriber about a patient with hepatic impairment. Frequently encountered barriers in practice were insufficient knowledge on the topic and a lack of essential patient information (i.e. diagnosis and severity of the impairment).

Conclusion

Community pharmacists regularly evaluate the safety of medication in patients with hepatic impairment, yet their level of knowledge was insufficient and additional education is needed. Pharmacists experienced several difficulties in providing pharmaceutical care. If these issues are resolved, pharmacists can play a more active role in ensuring medication safety in their patients with hepatic impairment.

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.

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.
