Article Synopsis
  • The study compares the cost-effectiveness of MDMA-assisted therapy (MDMA-AT) for chronic PTSD against a placebo with therapy (PT) using a health state-transition model.
  • MDMA-AT costs about $64,745 and generates 3.691 quality-adjusted life years (QALYs), while PT costs $33,132 and yields 3.314 QALYs, yielding an incremental cost-effectiveness ratio (ICER) of $83,845 per QALY.
  • To remain within a $150,000 willingness-to-pay threshold, the maximum allowed cost for the MDMA sessions was determined to be $20,314 each, showing that MDMA-AT offers better utility and lower PTSD

Background: The purpose of this systematic literature review (SLR) was to evaluate the accuracy of noninvasive diagnostic tools in detecting significant or advanced (F2/F3) fibrosis among patients with nonalcoholic fatty liver (NAFL) in the US healthcare context.

Methods: The SLR was conducted in PubMed and Web of Science, with an additional hand search of public domains and citations, in line with the PRISMA statement. The study included US-based original research on diagnostic test sensitivity, specificity and accuracy.

Objectives: This study aimed to review definitions of digital health and understand their relevance for health outcomes research. Four umbrella terms (digital health, electronic health, mobile health, and telehealth/telemedicine) were summarized in this article.

Methods: PubMed/MEDLINE, Embase, Cochrane Library, and EconLit were searched from January 2015 to May 2020 for systematic reviews containing key Medical Subject Headings terms for digital health (n = 38) and synonyms of "definition.

Background: Our study aimed to compare real-world healthcare resource utilization (HRU) and healthcare cost (HC) of Medicare-insured patients (≥65 years old) with Dupuytren's contracture (DC) treated with (collagenase) or fasciectomy.

Methods: DC patients treated with collagenase or fasciectomy between July 2011 and June 2017 were identified using the IBM MarketScan Medicare Supplemental Database. The index date was the date of the first procedure.

Purpose: Opioid therapy for managing chronic pain remains a challenge, as providers must weigh the medical benefit to the patient with the risk of adverse events. Manipulation of many extended-release (ER) opioid formulations may lead to increased serious medical outcomes or death. The economic burden of opioid use disorders due to opioid misuse and abuse may vary depending on which abuse deterrent opioid formulation is prescribed.

Objective: To compare concomitant benzodiazepine (BZDs) use among chronic pain patients adherent to extended-release tapentadol (TapER) or oxycodone (OxnER) and estimate the number of lives potentially saved by switching pa-tients to the less BZD coprescribed treatment.

Design: Retrospective database study.

Setting: Patients were identified using the IBM MarketScan® Commercial Database.

Objective: Studies examining differences in US healthcare resource utilization (HCRU) and associated healthcare costs between collagenase clostridium histolyticum (CCH) and fasciectomy for Dupuytren contracture (DC) are limited. This study evaluated US HCRU and direct healthcare cost for the treatment of DC in privately insured patients using insurance claims.

Methods: This retrospective observational cohort study analyzed data from large nationwide insurance claims databases; it included individuals diagnosed with DC between July 1, 2011, and June 30, 2017, who were adults at index date (date of first treatment: CCH or fasciectomy).

: Lower limb bypass occlusion in patients with chronic limb threating ischemia remains a challenge. We can choose between different treatment options: open surgery, local thrombolysis, thrombectomy/atherectomy devices. In this pilot study, we compare clinical outcomes and treatment costs between open surgery (OS) and percutaneous mechanical thrombectomy (pMTH).

The development of evidence to demonstrate 'value for money' is regarded as an important step in facilitating the search for the optimal allocation of limited resources and has become an essential component in healthcare decision making. Real-world evidence collected from de-identified individuals throughout the continuum of healthcare represents the most valuable source in technology evaluation. However, in the European Union, the value assessment based on real-world data has become challenging as individuals have recently been given the right to have their personal data erased in the case of consent withdrawal or when the data are regarded as being no longer necessary.

: We conducted a comparative assessment of the productivity loss associated with the two different treatment options for Dupuytren's disease: collagenase and fasciectomy. : The retrospective claims analysis was performed using the data from IBM MarketScan® Commercial (CD) and Health and Productivity Management (HPM) Databases over five years (2012-2016). We identified two cohorts of patients who underwent either collagenase or fasciectomy in the CD.

Purpose: Chronic pain treatment imposes a substantial economic burden on US society. Treatment costs may vary across subgroups of patients with different types of pain. The aim of our study was to compare healthcare costs (HC) and resource utilization in musculoskeletal (MP), neuropathic (NP), and cancer pain (CaP) patients treated with long-acting opioids (LAO), using real-world evidence.

Objective: Recent years have witnessed an increased interest in the use of multicriteria decision analysis (MCDA) to support health technology assessment (HTA) agencies for setting healthcare priorities. However, its implementation to date has been criticized for being "entirely mechanistic," ignoring opportunity costs, and not following best practice guidelines. This article provides guidance on the use of MCDA in this context.

Introduction: As budget constraints become more and more visible, there is growing recognition for greater transparency and greater stakeholders' engagement in the pharmaceuticals' pric-ing&reimbursement (P&R) decision making. New frameworks of drugs' value assessments are searched for. Among them, the multi-criteria decision analysis (MCDA) receives more and more attention.

Background: Health technology assessments (HTAs) are increasingly used to inform coverage, access, and utilization of medical technologies including molecular diagnostics (MDx). Although MDx are used to screen patients and inform disease management and treatment decisions, there is no uniform approach to their evaluation by HTA organizations.

Objectives: The International Society for Pharmacoeconomics and Outcomes Research Devices and Diagnostics Special Interest Group reviewed diagnostic-specific HTA programs and identified elements representing common and best practices.

Introduction: According to some experts, there is still room for improvement with regard to the inclusion of ethical considerations in Health Technology Assessment (HTA).

Areas Covered: The pros and cons of the introduction of non-economic criteria in the HTA process in Central and Eastern Europe (CEE) are discussed. In comparison to Western Europe, financial considerations are even more important in CEE settings; however, it could also be said that attachment to equity and justice is part of CEE's heritage.
