Evaluating a Collaborative Approach to Improve Prior Authorization Efficiency in the Treatment of Hepatitis C Virus

Insurance Approval Delay of Biologic Therapy Dose Escalation Associated with Disease Activity in Patients with Inflammatory Bowel Disease

BACKGROUND

Dose escalation of self-injectable biologic therapy for inflammatory bowel diseases may be required to counteract loss of response and/or low drug levels. Payors often require completion of a prior authorization (PA), which is a complex approval pathway before providing coverage. If the initial PA request is denied, clinic staff must complete a time and resource-intensive process to obtain medication approval.

AIMS

This study measured time from decision to dose escalate to insurance approval and evaluated impact of approval time on disease activity.

METHODS

This was a single-center retrospective analysis of adult patients with IBD prescribed an escalated dose of biologic therapy at an academic center with an integrated specialty pharmacy team from January to December 2018. Outcomes included time to insurance approval and the association between approval time and follow-up C-reactive protein (CRP) and Short Inflammatory Bowel Disease Questionnaire (SIBDQ) scores. Associations were tested using linear regression analyses.

RESULTS

220 patients were included, median age 39, 53% female, and 96% white. Overall median time from decision to dose escalate to insurance approval was 7 days [interquartile range (IQR) 1, 14]. Approval time was delayed when an appeal was required [median of 29 days (IQR 17, 43)]. Patients with a longer time to insurance approval were less likely to have CRP improvement (p = 0.019). Time to insurance approval did not significantly impact follow-up SIBDQ scores.

CONCLUSION

Patients who had a longer time to insurance approval were less likely to have improvement in CRP, highlighting the negative clinical impact of a complex dose escalation process.

2022 ASHP Survey of Health-System Specialty Pharmacy Practice: Clinical Services

PURPOSE

Results of the first ASHP national survey of clinical services provided by health-system specialty pharmacies (HSSPs) are presented.

METHODS

A survey questionnaire was developed by 26 HSSP contacts after reviewing available literature on the role and services of HSSPs. After pilot and cognitive testing resulting in a final questionnaire of 119 questions, a convenience sample of 441 leaders in HSSPs was contacted using email and invited to participate in the survey.

RESULTS

The survey response rate was 29%. Almost half of respondents (48%) had offered pharmacy services for 7 years or more, and most (60%) dispensed more than 15,000 prescriptions annually. Respondents most commonly (42%) reported a specialist model wherein staff are dedicated to specific specialty disease states. Over half of respondents reported providing several medication access, pretreatment assessment, and initial counseling services to patients referred to them, regardless of whether the HSSP was used for medication fulfillment. All HSSP activities were noted to be documented in the electronic health record and visible to providers frequently or always. Almost all respondents noted that HSSP pharmacists have a role in specialty medication selection. Disease-specific outcomes were tracked in 95% of responding HSSPs, with 67% reporting that outcomes were used to drive patient monitoring. HSSPs were often involved in continuity of care services such as transitions of care (reported by 89% of respondents), referral to other health-system services (53%), and addressing social determinants of health (60%). Most respondents (80%) reported providing clinical education to specialty clinic staff, including medicine learners (62%). Though only 12% of respondents had dedicated outcomes research staff, many reported annually publishing (47%) or presenting (61%) outcomes research.

CONCLUSION

HSSPs are a clinical and educational resource for specialty clinics and have developed robust patient care services that encompass the patient journey from before specialty medication selection through treatment monitoring and optimization.

Health-system specialty pharmacy role and outcomes: A review of current literature

DISCLAIMER

In an effort to expedite the publication of articles, AJHP is posting manuscripts online as soon as possible after acceptance. Accepted manuscripts have been peer-reviewed and copyedited, but are posted online before technical formatting and author proofing. These manuscripts are not the final version of record and will be replaced with the final article (formatted per AJHP style and proofed by the authors) at a later time.

PURPOSE

Specialty medications can have life-altering outcomes for patients with complex diseases. However, their benefit relies on appropriate treatment selection, patients' ability to afford and initiate treatment, and ongoing treatment optimization based on patient response to therapy. Mounting research demonstrates the benefits of the health-system specialty pharmacy (HSSP) in improving specialty medication access, affordability, and outcomes. The purpose of this rapid review is to describe the currently reported role and function of HSSP pharmacists and outcomes reported with use of the HSSP model, and to identify gaps in the literature where more information is needed to better understand the HSSP model and outcomes.

SUMMARY

Current literature describes the role of HSSP pharmacists in facilitating patient access, affordability, and initiation and maintenance of specialty medications. Though it is clear HSSP pharmacists are involved in treatment monitoring, often through utilizing the electronic health record, more information is needed to elucidate the frequency, method, and extent of monitoring. Despite several valuable continuity of care services reported to be provided by HSSPs, the breadth and degree of standardization of these services remains unclear. There is minimal literature describing HSSP education and research involvement. HSSPs have reported significant benefits of this patient care model, as demonstrated by higher adherence and persistence; better clinical outcomes; financial benefits to patients, payers and the health system; better quality of care; higher patient and provider satisfaction with services, and highly efficient specialty pharmacy services. More literature comparing clinical and diagnosis-related outcomes in HSSP versus non-HSSP patients is needed.

CONCLUSION

HSSPs provide comprehensive, patient-centered specialty medication management that result in improved care across the continuum of the specialty patient journey and act as a valuable resource for specialty clinics and patients beyond medication management. Future research should build on the current description of HSSP services, how services affect patient outcomes, and the impact HSSP network restrictions.

Impact of Removing Medicaid Fee-for-Service Hepatitis C Virus (HCV) Treatment Restrictions on HCV Provider Experience with Medicaid Managed Care Organizations in New York City

Immediately after the approval of direct-acting antiviral medications for the treatment of hepatitis C virus (HCV) in 2013, state Medicaid programs limited access to these expensive treatments based on liver disease stage, absence of active alcohol or substance use, and prescriber limitations. New York State fee-for-service (FFS) Medicaid eliminated these requirements in May 2016, but the effect on providers and patients obtaining prior authorization (PA) from Medicaid managed care organizations (MCOs) was unknown. We used a mixed methods approach to assess whether the removal of HCV treatment restrictions was associated with changes in Medicaid MCOs' PA approval processes and length of time to treatment initiation at two large urban New York City provider organizations participating in Project INSPIRE, an HCV care coordination demonstration project. At baseline, the top criteria for clinic care coordinators ranking MCOs as being "most difficult" were liver staging criteria, delayed treatment, and requiring a urine toxicology test. At follow-up, liver staging criteria were replaced by medication formulary limitations. Univariate analysis of the Project INSPIRE participant data suggests a decrease in the percentage of participants with insurance/PA-related treatment delays pre- versus post-policy change (23% versus 15%, p value = 0.02). Interrupted time series analysis found a 2 percentage point decrease (p value = 0.02) in the proportion of PAs each month with insurance-related treatment delays that was attributable to policy change. These results from two urban clinics indicate New York State FFS Medicaid's policy change for HCV treatment may have been associated with some changes in Medicaid MCO PA decisions, but MCO PA denials and treatment delays were still observed "on the ground" by clinic staff.

A Telementoring Program and Hepatitis C Virus Care in Rural Patients

Background: Rural patients with chronic hepatitis C virus (HCV) infection may be less likely to access HCV care than those in urban areas. A telementoring, task-shifting model has been implemented to address the unmet needs of HCV care. Evidence is needed on whether this intervention improves HCV care in rural HCV patients. Methods: We compared three key HCV care indicators among Medicare patients with chronic hepatitis C in 2014-2016 by urban-rural status between New Mexico with a telementoring program and Pennsylvania without such a program. We classified each patient's urban-rural status based on his or her ZIP code of residence. We used multivariable log-binomial regressions to examine the relative probability of receiving HCV care by urban and rural status in two states. Results: In New Mexico, 41.3% of HCV patients resided in rural areas (N = 1155). In Pennsylvania, rural patients accounted for 13.2% (N = 1775). The unadjusted overall rates of receiving HCV RNA or genotype testing within 12 months before HCV treatment were 76.1% in "rural-New Mexico" versus 73.3% in "rural-Pennsylvania," 66.2% in "urban-New Mexico," and 70.2% in "urban-Pennsylvania." Post-treatment HCV RNA testing rate was also high in "rural-New Mexico" (83.0%). After adjusting for demographic and clinical characteristics, "rural-New Mexico" HCV patients who received HCV treatment still had the highest probability of taking HCV RNA or genotype testing before HCV treatment, compared with other groups (relative risk [95% confidence interval]: 0.91 [0.84-1.00] in "rural-Pennsylvania," 0.85 [0.78-0.93] in "urban-New Mexico," and 0.93 [0.87-1.00] in "urban-Pennsylvania"). Conclusions: The telementoring program may help improve HCV care in rural patients.

A comparison of medication access services at 340B and non-340B hospitals

BACKGROUND

For patients that face barriers to filling their prescriptions, the availability of medication access services at their site of care can mean the difference between receiving prescribed drug therapy, and undue interruptions in care. Hospitals often provide medication access services that are not reimbursed by payers; however, they can be challenging to sustain. The 340B Drug Pricing Program allows covered entities to generate savings through discounted pricing for certain outpatient medications, which can then be used to provide more comprehensive services, including medication access services.

OBJECTIVE

To characterize medication access services provided at hospitals that participate in the 340B Drug Pricing Program compared to hospitals that do not participate in the 340B Program.

METHODS

Primary questionnaire response data was collected from a national sample of Directors of Pharmacy at non-federal acute care hospitals from March 2019 to May 2019. American Hospital Association Data Viewer was used to collect demographic information on 1,531 hospitals. Hospitals were excluded if they had 199 beds or fewer, did not have a unique Medicare provider ID, were federally owned, were located outside the continental U.S., or were non-acute care hospitals that served niche patient populations. This study utilized a proportional stratified sampling strategy to administer an electronic questionnaire to 340B and non-340B hospitals to assess the number and type of medication access service offerings. A final randomized sample of 500 hospitals were administered the questionnaire, and data was collected through recorded responses in Qualtrics software.

RESULTS

340B hospitals provided a significantly higher average number of medication access services compared to non-340B hospitals (6.20 vs. 3.91, p = 0.0001), adjusted for differences in hospital size and ownership type. For all nine medication access services that were assessed, a higher percentage of 340B hospitals reported providing the service compared to non-340B hospitals. This difference was statistically significant for six out of nine programs assessed.

CONCLUSIONS

340B hospitals provided more medication access services, on average, than comparably sized non-340B hospitals, suggesting that hospitals participating in the 340B Drug Pricing Program may be better positioned to create and administer programs that support medication access services.

Embedding an Advanced Pharmacy Technician in an Adult Specialty Pulmonary Clinic to Complete Prior Authorizations Improves Efficiency and Provider Satisfaction

PURPOSE

The purpose of this study is to assess the impact of a clinic embedded Medication Assistance Program (MAP) specialist on the prescription benefit prior authorization (PA) process and provider satisfaction in an adult pulmonary clinic.

METHODS

In this mixed methods study, a retrospective cohort analysis was done to determine the turnaround time for the PA process from initial referral to approval or final denial in an adult pulmonary clinic. Additionally, a pre- and post-implementation survey to providers was conducted to assess provider satisfaction and perceptions around the prescription benefit PA process. The first study aim assessed PA efficiency by summarizing PA approval rate and PA turnaround time using descriptive statistics. Any prescriptions written by a clinic provider requiring a PA during the timeframe of June 2018 through August 2018 were included. The second study aim assessed change in provider satisfaction, analyzed via the Mann-Whitney U test.

RESULTS

The MAP specialist completed 110 PAs over 3 months for 110 unique patients. Median turnaround time was 3 hours, with 76% of PAs approved in less than 24 hours. Initial approval rate was 82.7%, and overall approval rate following the appeals process was 87.3%. A significant difference between the pre- and post-survey responses were identified in 2 of the 17 questions.

CONCLUSION

Implementation of a clinic embedded MAP specialist to complete PAs demonstrated an efficient process while also improving provider satisfaction.

Psychosocial Obstacles to Hepatitis C Treatment Initiation Among Patients in Care: A Hitch in the Cascade of Cure

There are limited data examining the relationship between psychosocial factors and receipt of direct-acting antiviral (DAA) treatment among patients with hepatitis C in large health care organizations in the United States. We therefore sought to determine whether such factors were associated with DAA initiation. We analyzed data from an extensive psychological, behavioral, and social survey (that incorporated several health-related quality of life assessments) coupled with clinical data from electronic health records of patients with hepatitis C enrolled at four health care organizations during 2017-2018. Of 2,681 patients invited, 1,051 (39.2%) responded to the survey; of 894 respondents eligible for analysis, 690 (77.2%) initiated DAAs. Mean follow-up among respondents was 9.2 years. Compared with DAA recipients, nonrecipients had significantly poorer standardized scores for depression, anxiety, and life-related stressors as well as poorer scores related to physical and mental function. Lower odds of DAA initiation in multivariable analysis (adjusted by age, race, sex, study site, payment provider, cirrhosis status, comorbidity status, and duration of follow-up) included Black race (adjusted odds ratio [aOR], 0.59 vs. White race), perceived difficulty getting medical care in the preceding year (aOR, 0.48 vs. no difficulty), recent injection drug use (aOR, 0.11 vs. none), alcohol use disorder (aOR, 0.58 vs. no alcohol use disorder), severe depression (aOR, 0.42 vs. no depression), recent homelessness (aOR, 0.36 vs. no homelessness), and recent incarceration (aOR, 0.34 vs. no incarceration). Conclusion: In addition to racial differences, compared with respondents who initiated DAAs, those who did not were more likely to have several psychological, behavioral, and social impairments. Psychosocial barriers to DAA initiation among patients in care should also be addressed to reduce hepatitis C-related morbidity and mortality.

Changing Urban-Rural Disparities in the Utilization of Direct-Acting Antiviral Agents for Hepatitis C in U.S. Medicare Patients, 2014-2017

INTRODUCTION

The advent of direct-acting antiviral agents for treating hepatitis C virus infection has made hepatitis C virus elimination possible. Rural patients with hepatitis C virus infection may be less likely to access direct-acting antiviral agents, but the real-world evidence is scarce on urban-rural disparities in direct-acting antiviral agent utilization.

METHODS

This retrospective cohort study was conducted in 2019-2020 using Medicare data to examine urban-rural disparities in direct-acting antiviral agent utilization among newly diagnosed patients with hepatitis C virus infection in 2014-2016. Direct-acting antiviral agent use was defined as filling ≥1 prescription for direct-acting antiviral agents during 2014-2017, and patient's urban-rural status was classified on the basis of their ZIP code of residence. This study evaluated the associations between multilevel factors and direct-acting antiviral agent use with a focus on urban-rural disparities. It also assessed changes over time in urban-rural disparities in direct-acting antiviral agent utilization using multivariable cause-specific Cox regression analyses with time-varying hazard ratios.

RESULTS

Among 204,018 new patients with hepatitis C virus infection, about 30% received direct-acting antiviral agents during 2014-2017. Cumulative direct-acting antiviral agent use gradually increased over time in both urban and rural patients. However, the increase was greater in urban patients than in rural patients. In the first year of follow-up, rural patients had a similar rate of receiving direct-acting antiviral agents (adjusted hazard ratio=1.03, 95% CI=1.00, 1.07), but they were less likely to use direct-acting antiviral agents in later years than urban patients (adjusted hazard ratio=0.85, 95% CI=0.81, 0.90 in the second year, adjusted hazard ratio=0.82, 95% CI=0.76, 0.89 in the third year, and adjusted hazard ratio=0.76, 95% CI=0.64, 0.90 in the fourth year of follow-up).

CONCLUSIONS

This study reveals important gaps in hepatitis C virus treatment and suggests increasing urban-rural disparities in direct-acting antiviral agent utilization. Enhancing direct-acting antiviral agent uptake in rural populations with hepatitis C virus infection will help reduce hepatitis C virus‒related health disparities and reach the national goal of eliminating hepatitis C virus infection.

Can Telementoring Reduce Urban-Rural Disparities in Utilization of Direct-Acting Antiviral Agents?

Background: Expanding access to direct-acting antiviral agents (DAAs) for treating hepatitis C virus (HCV) infection is the national goal for HCV elimination, but important urban-rural disparities exist in DAA use. Evidence is needed to evaluate intervention efforts to reduce urban-rural disparities in DAA utilization. Methods: We used Medicare data to compare DAA use between urban HCV patients and rural HCV patients in two states: State A with a telementoring approach to train rural providers to treat HCV patients and State B without such an intervention. We focused on DAA utilization among newly diagnosed HCV patients in 2014-2016 and defined DAA use as filling at least one prescription of DAAs during 2014-2017. We classified patient's urban-rural status based on their ZIP code of residence. We assessed overtime changes in urban-rural disparities in DAA utilization for each state using multivariable cause-specific Cox regression analyses with time-varying hazard ratios. Results: Among 1,872 new HCV patients in State A, 135 (17.00%) rural patients and 243 (22.54%) urban patients received DAAs in 2014-2017. Although there was noticeable urban-rural disparities in DAA use during the first 24 months of follow-up (hazard ratios [HRs] = 0.73 [0.51 to 1.03] for 0-12 months and 0.61 [0.39 to 0.95] for 13-24 months), the disparities became nonsignificant afterward (HR = 1.06 [0.58 to 1.93] after 24 months). Most DAA users in rural areas (94, 70%) in State A received DAAs prescribed by primary care providers (PCPs). In State B, among 8,928 new HCV patients, 227 (18.22%) rural patients and 1,600 (20.83%) urban patients received DAAs in 2014-2017. Rural patients were less likely to receive DAAs over time (HR = 1.12 [0.93 to 1.36] in the first 12 months and HR = 0.62 [0.40 to 0.96] after 24 months). Only 81 (36%) DAA users in rural areas in State B were treated by PCPs. Conclusions: Our study suggests that the telementoring approach may help reduce urban-rural disparities in DAA utilization.

Case Management and Capacity Building to Enhance Hepatitis C Treatment Uptake at Community Health Centers in a Large Urban Setting

An estimated 4.1 million people in the United States are infected with hepatitis C virus (HCV). In 2014, the Hepatitis C Community Alliance to Test and Treat (HepCCATT) collaborative was formed to address hepatitis C in Chicago. From 2014 to 2017, the HepCCATT Case Management Program case managed 181 HCV-infected people and performed on-site capacity building at a 6-site community health center (CHC) that produced codified protocols, which were translated into a telehealth program to build capacity within CHCs to deliver hepatitis C care. HepCCATT's innovative approach to addressing multilevel barriers is a potential model for increasing access to hepatitis C care and treatment.

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.

PH Professional Network: The Burden of Prior Authorization for Pulmonary Hypertension Medications: A Practical Guide for Managing the Process

Medications for pulmonary hypertension (PH) are expensive and often require prior authorization from insurance payers. The task of submitting prior authorization requests and appealing denials can burden PH practices with a heavy workload and delay or interrupt medical treatment. However, it is possible to reduce this burden, improve success rates, and reduce waiting times by implementing a standard office workflow for managing the prior authorization process. Such a system involves several key components: assessment of existing staff and level of expertise; dedicated office staff to oversee the process from start to finish; streamlined gathering, storage, and transmittal of patient documents; direct communication with pharmacies and Risk Evaluation Mitigation Strategy programs; and careful documentation of PH diagnosis and treatment plans for a given patient, aimed at reducing the necessity for appeals. This article reviews prior authorization strategies and systems used at PH clinics, and case studies in other therapeutic areas that demonstrate how such systems can reduce staff time and waiting time for initiation of medications while improving the rate of success. The article also describes the special challenges of requesting prior authorization for PH medications prescribed to pediatric patients.

Building a Hepatitis C Clinical Program: Strategies to Optimize Outcomes

PURPOSE OF REVIEW

An increasing number of specialists and non-specialists are developing clinical programs to treat and cure hepatitis C virus (HCV). The goal of this paper is to evaluate and describe optimal strategies to improve outcomes related to HCV care delivery.

RECENT FINDINGS

Screening and diagnosis of HCV should be guided by established recommendations. Given the recognized disparity in HCV diagnosis and linkage to care, a multi-modal approach involving care coordination and technology resources should be used to improve patient engagement. Access to HCV treatment may be optimized through systematic documentation, prior authorization, and appeal processes. Treatment monitoring should emphasize medication adherence, side effect and drug interaction management, as well as elimination of practical barriers. Finally, post-treatment engagement to promote liver health and reduce the risk of complications or reinfection maximizes the benefit of HCV treatment.

SUMMARY

The landscape of HCV treatment has evolved from a specialist-driven model with few patients qualifying for treatment to an opportunity for non-specialists and other providers to provide curative therapies in most patients. Innovative practice models that employ a multidisciplinary approach will likely improve screening, diagnosis, engagement, and treatment outcomes.

Hepatitis C Management Simplification From Test to Cure: A Framework for Primary Care Providers

This article proposes a strategy for primary care providers to begin treating patients with hepatitis C virus (HCV). We are motivated by the need to expand HCV treatment and by developments that have simplified treatment for most patients. This article presents 5 steps to achieving quality HCV treatment in the primary care setting: (1) accurate diagnosis via reflex testing; (2) risk stratification and identifying comorbidities via pretreatment evaluation; (3) simple, once-daily, pan-genotypic HCV treatment regimens; (4) minimized on-treatment monitoring: and (5) posttreatment monitoring and high-quality care for comorbidities such as cirrhosis and injection drug use. We provide indications for referral to specialists: notably children, patients with genotype 3 and cirrhosis, advanced liver or kidney disease, previous treatment failures, drug interactions with recommended regimens, and hepatitis B co-infection. Finally, potential barriers for providers are discussed, as well as further research findings and policy interventions that can promote HCV treatment in the primary care setting. We believe that a substantial portion of patients with HCV can be treated safely and effectively by nonspecialists and that the engagement of primary care providers is critical to efforts to end the HCV epidemic.
