Abstract
PURPOSE This descriptive report describes the process used to obtain access to providing ambrisentan from a health-system specialty pharmacy (HSSP) affiliated with a pulmonary hypertension Center of Comprehensive Care, develop a pulmonary arterial hypertension (PAH) care team at the HSSP, and characterize medication adherence and access metrics. SUMMARY PAH is a rare disease treated with several specialty medications requiring intensive monitoring. Historically, specialty medications used to treat PAH have been provided by only select specialty pharmacies due to restricted drug distribution channels. It is recommended that patients with PAH receive their care at centers with expertise in the diagnosis and management of this disorder, but the HSSPs at these expert centers are unable to provide specialty PAH medications. The current care model for PAH leads to patients receiving their medical and pharmaceutical care from separate entities. This descriptive report describes a multidisciplinary team's approach to gaining access to providing ambrisentan and developing a disease state care team within an established HSSP. After implementing this service, specialty pharmacy metrics were assessed, including proportion of days covered (PDC), time to first fill, patient contact rate, Risk Evaluation and Mitigation Strategy (REMS) program compliance, time to prior authorization (PA) approval, rate of optimal adherence (PDC of >80%), and PA renewal rate, to demonstrate a proof-of-concept HSSP model for PAH. In this model, the HSSP was able to demonstrate high-quality specialty pharmacy metrics with regard to medication adherence, medication access, and REMS program compliance. CONCLUSION The development of a PAH care team to provide ambrisentan at an existing HSSP was associated with high adherence rates, efficient and reliable medication access, and REMS program compliance.

Abstract
BACKGROUND The aim of this study was to assess health care resource utilization (HRU) and costs associated with delayed pulmonary arterial hypertension (PAH) diagnosis in the United States. METHODS Eligible adults with newly diagnosed PAH from Optum's de-identified Clinformatics® Data Mart Database (2016-2021) were assigned to mutually exclusive cohorts based on time between first PAH-related symptom and first PAH diagnosis (i.e., ≤12 months' delay, >12 to ≤24 months' delay, >24 months' delay). All-cause HRU and health care costs per patient per month (PPPM) were assessed during the first year following diagnosis and compared across cohorts using regression analysis adjusted for baseline covariates. Sensitivity analyses were conducted to assess outcomes during all available follow-up post-diagnosis. RESULTS Among 538 patients (mean age: 65.6 years; 60.6% female), 60.8% had ≤12 months' delay, 23.4% had a delay of >12 to ≤24 months, and 15.8% had >24 months' delay. Compared with ≤12 months, delays of >12 to ≤24 months and >24 months were associated with increased hospitalizations (incidence rate ratio [95% confidence interval]: 1.40 [1.11-1.71] vs 1.71 [1.29-2.12]) and outpatient visits (1.17 [1.06-1.30] vs 1.26 [1.08-1.41]). Longer delays were also associated with more intensive care unit (ICU) stays and 30-day readmissions. Diagnosis delays translated into excess costs PPPM of US$3986 [1439-6436] for >12 to ≤24 months and US$5366 [2107-8524] for >24 months compared with ≤12 months' delay; increased hospitalization costs (US$3248 [1108-5135] and US$4048 [1401-6342], respectively) being the driver. Sensitivity analyses yielded similar trends. CONCLUSIONS Delayed PAH diagnosis is associated with significant incremental economic burden post-diagnosis, driven by hospitalizations including ICU stays and 30-day readmissions, highlighting the need for increased awareness and a potential benefit of earlier screening.

Population Health Model Predicting the Long-Term Impact of Sotatercept on Morbidity and Mortality in Patients with Pulmonary Arterial Hypertension (PAH). Adv Ther 2024; 41:130-151. [PMID: 37851297 PMCID: PMC10796519 DOI: 10.1007/s12325-023-02684-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/15/2023] [Accepted: 09/08/2023] [Indexed: 10/19/2023]
Abstract
INTRODUCTION Pulmonary arterial hypertension (PAH) is a rare, progressive disease associated with significant morbidity and mortality. The phase 3 STELLAR trial tested sotatercept plus background therapy (BGT) versus placebo plus BGT. BGT was comprised of mono-, double-, or triple-PAH targeted therapy. Building on STELLAR findings, we employed a population health model to assess the potential long-term clinical impact of sotatercept. METHODS Based on the well-established ESC/ERS 4-strata risk assessment approach, we developed a six-state Markov-type model (low risk, intermediate-low risk, intermediate-high risk, high risk, lung/heart-lung transplant, and death) to compare the clinical outcomes of sotatercept plus BGT versus BGT alone over a lifetime horizon. State-transition probabilities were obtained from STELLAR. Risk stratum-adjusted mortality and lung/heart-lung transplant probabilities were based on COMPERA PAH registry data, and the post-transplant mortality probability was obtained from existing literature. Model outcomes were discounted at 3% annually. Sensitivity analyses were conducted to examine model robustness. RESULTS In the base case, sotatercept plus BGT was associated with longer life expectancy from model baseline (16.5 vs 5.1 years) versus BGT alone, leading to 11.5 years gained per patient. Compared with BGT alone, sotatercept plus BGT was further associated with a gain in infused prostacyclin-free life years per patient, along with 683 PAH hospitalizations and 4 lung/heart-lung transplant avoided per 1000 patients. CONCLUSIONS According to this model, adding sotatercept to BGT increased life expectancy by roughly threefold among patients with PAH while reducing utilization of infused prostacyclin, PAH hospitalizations, and lung/heart-lung transplants. Real-world data are needed to confirm these findings. TRIAL REGISTRATION ClinicalTrials.gov identifier, NCT04576988 (STELLAR).

Assessment of Knowledge, Attitude, and Practice Patterns in Pulmonary Arterial Hypertension among Cardiologists and Pulmonologists: Evidence from Turkey. MEDICINA (KAUNAS, LITHUANIA) 2023; 59:1869. [PMID: 37893587 PMCID: PMC10608633 DOI: 10.3390/medicina59101869] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/09/2023] [Revised: 10/03/2023] [Accepted: 10/18/2023] [Indexed: 10/29/2023]
Abstract
Background and Objectives: Pulmonary arterial hypertension (PAH) is a rare chronic disease of the small pulmonary arteries that causes right heart failure and death. Accurate management of PAH is necessary to decrease morbidity and mortality. Understanding current practices and perspectives on PAH is important. For this purpose, we intended to determine physicians' knowledge, attitudes, and practice patterns in adult pulmonary arterial hypertension (PAH) in Turkey. Materials and Methods: Between January and February 2022, an online questionnaire was sent via e-mail to all cardiologists and pulmonologists who were members of the Turkish Society of Cardiology (TSC) and the Turkish Thoracic Society (TTS). Results: A total of 200 physicians (122 pulmonologists and 78 cardiologists) responded to the questionnaire. Cardiologists were more frequently involved in the primary diagnosis and treatment of PAH than pulmonologists (37.2% vs. 23.8%, p = 0.042). More than half of the physicians had access to right heart catheterization. In mild/moderate PAH patients with a negative vasoreactivity test, the monotherapy option was most preferred (82.8%) and endothelin receptor antagonists (ERAs) were the most preferred group in these patients (73%). ERAs plus phosphodiesterase-5 inhibitors (PDE-5 INH) were the most preferred (69%) combination therapy, and prostacyclin analogues plus PDE-5 INH was preferred by only pulmonologists. Conclusions: Overall, clinical management of patients with PAH complied with guideline recommendations. Effective clinical management of PAH in specialized centers that having right heart catheterization achieve better outcomes.

[PMID: 36704610 PMCID: PMC9868346 DOI: 10.1002/pul2.12190] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/28/2022] [Revised: 01/03/2023] [Accepted: 01/05/2023] [Indexed: 01/11/2023] Open
Abstract
Pulmonary arterial hypertension (PAH) is a progressive disease with no cure. Healthcare resource utilization (HCRU; hospitalization, outpatient visits, and drug utilization) before diagnosis and productivity loss (sick leave and disability pension) before and after PAH diagnosis are not well known. By linking several Swedish national databases, this study have estimated the societal costs in a national PAH cohort (n = 749, diagnosed with PAH in 2008-2019) 5 years before and 5 years after diagnosis and compared to an age, sex, and geographically matched control group (n = 3745, 1:5 match). HCRU and productivity loss were estimated per patient per year. The PAH group had significantly higher HCRU and productivity loss compared to the control group starting already 3 and 5 years before diagnosis, respectively. HCRU peaked the year after diagnosis in the PAH group with hospitalizations (mean ± standard deviation; 2.0 ± 0.1 vs. 0.2 ± 0.0), outpatient visits (5.3 ± 0.3 vs. 0.9 ± 0.1), and days on sick leave (130 ± 10 vs. 13 ± 1) significantly higher compared to controls. Total costs during the entire 10-year period were six times higher for the PAH group than the control group. In the 5 years before diagnosis the higher costs were driven by productivity loss (76%) and hospitalizations (15%), while the 5 years after diagnosis the main cost drivers were drugs (63%), hospitalizations (16%), and productivity loss (16%). In conclusion, PAH was associated with large societal costs due to high HCRU and productivity loss, starting several years before diagnosis. The economic and clinical burden of PAH suggests that strategies for earlier diagnosis and more effective treatments are warranted.
