Insurance Approval Delay of Biologic Therapy Dose Escalation Associated with Disease Activity in Patients with Inflammatory Bowel Disease. Dig Dis Sci 2023; 68:4331-4338. [PMID: 37725192 DOI: 10.1007/s10620-023-08098-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/19/2022] [Accepted: 08/26/2023] [Indexed: 09/21/2023]
Abstract
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.

Abstract
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.

Adherence and persistence to self-administered disease-modifying therapies in patients with multiple sclerosis: A multisite analysis. Mult Scler Relat Disord 2023; 75:104738. [PMID: 37182475 DOI: 10.1016/j.msard.2023.104738] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/30/2022] [Revised: 04/19/2023] [Accepted: 04/27/2023] [Indexed: 05/16/2023]
Abstract
BACKGROUND Though there are several disease-modifying therapy (DMT) options for patients with multiple sclerosis (MS), treatment outcomes rely on patient adherence and persistence. Previous studies have demonstrated suboptimal adherence rates and high rates of early treatment discontinuation. Health-system specialty pharmacies (HSPPs) are a growing practice model that have demonstrated adherence and persistence benefits through single site evaluations. Research is needed across multiple HSSPs to understand and validate the outcomes of this practice model. METHODS A multisite prospective cohort study was performed including patients with at least three fills of a DMT between January 2020 and June 2021 at an HSSP. Patients were excluded due to pregnancy or death. Enrollment occurred for 6 months followed by 12 months of follow-up. Adherence was measured using pharmacy claims to calculate proportion of days covered (PDC) during the follow-up period. Time to non-persistence was calculated as the time from an index DMT fill to the first date of a gap of >60 days between medication exhaust and fulfillment dates. Adherence and persistence calculations were assessed at the therapeutic class level (any self-administered DMT dispensed by the HSSPs). The Kaplan-Meier method was used to present the probability of being persistent, and Cox proportional hazards regression analysis was used to estimate hazard ratios of factors associated with non-persistence, which included age, sex, study site, insurance type, and whether the patient switched medication as potential factors. RESULTS The most common self-administered DMTs filled among 968 patients were glatiramer acetate (32%), fingolimod (18%), and dimethyl fumarate (18%). Most patients (96%) did not switch DMT during the study period. The median PDC was 0.97 (interquartile range 0.90-0.99), which was similar across all sites. Patients who had at least one DMT switch were 76% less likely to have a higher PDC than those who did not have any switch after adjusting for other covariates (Odds ratio: 0.24, 95% confidence interval [CI]: 0.14-0.40, p<0.001). Most patients (86%) were persistent to DMT over the 12-month study period. Among those non-persistent, median time to non-persistence was 231 (IQR 177-301) days. Patients who switched medications were 2.4 times more likely to be non-persistent (95% CI: 1.3 - 4.5, p = 0.005). The most common reasons for non-persistence were discontinuation/medication held for an extended period (30%), often due to patient or prescriber decision (75%). CONCLUSION High rates of DMT adherence and persistence were seen among patients serviced by HSSPs, indicating potential benefits of this model for patients with MS. Switching DMTs was associated with lower adherence and persistence and may be an opportunity for added care coordination or resources to optimize therapy transitions.

Abstract
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.

Abstract
BACKGROUND Chronic hepatitis C virus (HCV) infections are increasing among reproductive age individuals. Direct acting antivirals (DAAs) can cure HCV, but the use of DAAs is not currently recommended during pregnancy and breastfeeding. Individuals with HCV commonly have inadequate prenatal and postnatal care. OBJECTIVES The purpose of our study was to demonstrate the success of a quality improvement program to increase evaluation during pregnancy and ensuring access to DAA treatment medication during the postpartum period for individuals with chronic HCV to achieve cure 12 weeks after completing therapy. The primary outcome was documented HCV cure rate compared among individuals who received immediate treatment with DAA after delivery or after weaning or a traditional approach of referral to an infectious diseases specialist or hepatologist. The secondary outcome was the proportion of infants exposed to HCV evaluated. METHODS An interdisciplinary team developed a program to increase evaluation and HCV treatment for postpartum individuals. Individuals who received prenatal care from March 2017 to May 2021 were eligible. Individuals with chronic HCV had a laboratory evaluation before delivery, and appropriate DAAs were selected for postpartum treatment. The health system specialty pharmacy dispensed DAA prescriptions immediately after delivery to those who were not breastfeeding. Individuals who did breastfeed had the option to begin treatment after weaning. Cure was defined as a sustained viral response or undetectable HCV RNA collected 12 weeks after completing DAA treatment. RESULTS We demonstrate the success of an interdisciplinary team to ensure access to therapy for the treatment of postpartum chronic HCV. Only 3 infants (25%) with mothers referred were evaluated at our institution compared with 44% of infants (n = 10) whose mothers were treated after delivery. CONCLUSION An interdisciplinary team for HCV treatment improves access to treatment therapy with DAAs leading to the cure of chronic HCV after delivery.

Abstract
PURPOSE Direct-acting antivirals (DAAs) used to treat hepatitis C virus (HCV) infection are associated with significant drug-drug interactions (DDIs). Pharmacists are well positioned to identify and mitigate these DDIs. Data to guide assessment of the impact of HCV specialty pharmacy services on identifying and addressing DDIs with DAAs are lacking. The overall purpose of the study described here was to determine the incidence and severity of DDIs identified by specialty pharmacists among patients treated with DAAs prior to and 1 month into therapy. METHODS An observational, retrospective study was conducted to evaluate the impact of specialty pharmacy services in mitigating DDIs associated with use of DAAs. Adult patients with HCV infection (n = 200) who received DAAs and were enrolled with a specialty pharmacy service over a 1-year period were included. Endpoints included number, severity, and type of DDIs and DDIs per patient at baseline and 1 month into therapy, pharmacists' interventions, and safety and clinical outcomes. RESULTS Fifty-nine percent of patients had at least 1 DDI. A total of 170 DDIs were identified (137 at baseline and 33 at 1-month follow-up), and the mean number of DDIs per patient significantly decreased from baseline to 1-month follow-up (from 1.38 to 0.16, P < 0.0001). The rate of "potentially clinically significant" or "critical" interactions was significantly lower at 1-month follow-up vs baseline assessment (69.6% vs 81.7%, P < 0.0001). The most commonly identified DDIs involved acid suppressive medications (49.6% and 66.6% of DDIs at baseline and follow-up assessment, respectively) and cardiovascular medications (26.2% and 21.2%, respectively). Total number of DDI interventions was 131, with an acceptance rate of 85%. Most common intervention was patient education and monitoring. CONCLUSION Approximately 60% of patients had DDIs with DAAs. Implementing HCV specialty pharmacy services significantly decreased DDIs while maintaining SVR12.

Abstract
BACKGROUND: In 2019, the Utilization Review Accreditation Commission (URAC) required a new reporting measure for specialty pharmacies related to completion of therapy for hepatitis C virus (HCV). OBJECTIVE: To calculate HCV completion of therapy according to URAC criteria and compare it with a calculation with additional pharmacy proposed adjustments to assess its applicability. METHODS: This was an observational study of patients who received HCV treatment with a direct-acting antiviral (DAA) from 1 specialty pharmacy. All patients with prescription claims at a pharmacy who had a first fill for a DAA medication between the 2 measurement periods of January 1, 2018-December 31, 2018, and January 1, 2019-December 31, 2019, were included. Additional information was collected via a retrospective chart review and from the pharmacy's electronic medication system. The cumulative gap according to URAC was calculated from claims data by summing the number of days between the last days supply of 1 claim for the prescribed DAA and the subsequent claims. The pharmacy-proposed cumulative gap was calculated using additional information from patient chart notes in order to account for a true start date. RESULTS: A total of 1,485 patients were identified as having a first fill of a DAA between the 2 measurement periods. The HCV completion of therapy measure calculated per the URAC definition was 83.4% in 2018 and 86.5% in 2019. The only variable significantly associated with a > 15-day gap according to the URAC definition was if the first DAA order was delivered to the prescriber's office instead of the patient's home for 2018 (χ2 [1, N = 573] = 16.8, P < 0.001) and 2019 (χ2 [1, N = 836] = 12.6, P < 0.001). Using the pharmacy-proposed adjustment, the modified HCV completion rates for 2018 and 2019 were 88.9% and 89.9%, respectively. CONCLUSIONS: The accrediting body's definition of completion of therapy may report a falsely high rate of gaps in HCV therapy due to not accounting for the actual DAA start date. This information may prove beneficial for the accrediting body, as it reviews its initial definition of the HCV completion of therapy measure. DISCLOSURES: No outside funding supported this study. Levesque reports participation in AbbVie's speaker's bureau with regard to its immunology portfolio. The other authors have no possible financial or personal relationships with commercial entities to disclose that may have a direct or indirect interest in the matter of this study.

Abstract
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.

Evaluation of pharmaceutical intervention in direct-acting antiviral agents for hepatitis C virus infected patients in an ambulatory setting: a retrospective analysis. J Pharm Health Care Sci 2018; 4:17. [PMID: 30026959 PMCID: PMC6048910 DOI: 10.1186/s40780-018-0113-3] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/18/2018] [Accepted: 06/06/2018] [Indexed: 01/17/2023] Open
Abstract
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.
