Educational Note: Paradoxical collider effect in the analysis of non-communicable disease epidemiological data: a reproducible illustration and web application

Classical epidemiology has focused on the control of confounding, but it is only recently that epidemiologists have started to focus on the bias produced by colliders. A collider for a certain pair of variables (e.g. an outcome Y and an exposure A) is a third variable (C) that is caused by both. In a directed…

Economic evaluation of the treatment of Acute Bacterial Skin and Skin Structure Infections (ABSSSIs) from the national payer perspective: introduction of a new treatment to the patient journey. A simulation of three European countries

Background: The aim of this study was to develop a spending predictor model to evaluate the direct costs associated with the management of ABSSSIs from the National health-care provider’s perspective of Italy, Romania, and Spain. Methodology: A decision-analytic model was developed to evaluate the diagnostic and clinical pathways of hospitalized ABSSSI patients based on scientific…

Economic evaluation of adjuvant therapy with osimertinib in patients with early-stage non–small cell lung cancer and mutated EGFR

Purpose The ADAURA trial demonstrated the superiority of osimertinib over a placebo with regard to disease-free survival, showing it to be indicated as an adjuvant therapy for treatment of non–small cell lung cancer with mutated epidermal growth factor receptor (EGFR). The aim of the present study was to conduct a cost-utility analysis and an analysis…

Economic assessment of abemaciclib for the adjuvant treatment of luminal HER2- breast cancer from the perspective of the Spanish health system

Introduction Abemaciclib is an oral inhibitor of cyclin-dependent kinases 4 and 6 (CDK4/6). Data from the clinical trial monarchE (2023) showed improved survival from invasive disease. The aim of the present article was to conduct an economic assessment of adjuvant treatment with abemaciclib in women with luminal, HER2- and node-positive breast cancer. Methods A Markov…

Economic Analysis of Cochlear Implants in Adults With Bilateral Severe-to-Profound Hearing Loss. A Systematic Review of the Literature

Objective To determine the cost-effectiveness or cost-utility of cochlear implants (CI) in adults with severe to profound bilateral hearing loss. Databases Reviewed PubMed (Medline), The Cochrane Library, Embase via Elsevier, EBSCOhost CINAHL, and Scopus. Methods The study included adult participants with severe to profound bilateral neurosensory hearing loss. The analysis encompassed quality of life improvements,…

Early mortality in multiple myeloma: the time-dependent impact of comorbidity. A population-based study in 621 real-life patients

Multiple myeloma is a heterogeneous disease with variable survival; this variability cannot be fully explained by the current systems of risk stratification. Early mortality remains a serious obstacle to further improve the trend towards increased survival demonstrated in recent years. However, the definition of early mortality is not standardized yet. Importantly, no study has focused…

Duration of the patient interval in breast cancer and factors associated with longer delays in low- and middle-income countries: A systematic review with meta-analysis

Objective Breast cancer survival is lower in low- and middle-income countries (LMICs) partially due to many women being diagnosed with late-stage disease. The patient interval refers to the time elapsed between the detection of symptoms and the first consultation with a healthcare provider and is considered one of the core indicators for early diagnosis and…

Does the use of health technology assessment have an impact on the utilisation of health care resources? Evidence from two European countries

Objectives A centralised approach to health technology assessment (HTA) may facilitate optimal use of HTA resources. A regional approach may increase the chances of local implementation of recommendations. This study aimed to compare assessment procedures in England (centralised HTA approach) with Spain (regional HTA approach) discussing key challenges and opportunities from both approaches. Methods We…
