A Review of the Evidence from the Middle Eastern Countries on the Facilitators and Barriers of Pharmacoeconomic Studies

Saud Tan*

Pharmacoeconomic studies provide valuable information for healthcare decision-makers by assessing the economic impact of pharmaceutical interventions. Despite their importance, such studies face several challenges and barriers that may hinder their conduct and implementation. This review aims to explore the barriers and facilitators of pharmacoeconomic studies in Middle Eastern countries and suggest potential solutions to overcome these challenges.A systematic review was conducted by searching PubMed, Embase, and Scopus databases for relevant articles published from January 2010 to December 2021. The search was limited to studies conducted in Middle Eastern countries and those reporting on barriers and facilitators of pharmacoeconomic studies. The quality of the included studies was assessed using the Critical Appraisal Skills Program tool. A total of 25 studies were included in this review. The main barriers to conducting pharmacoeconomic studies in Middle Eastern countries included limited funding, lack of trained personnel, inadequate data availability, and cultural barriers. On the other hand, the main facilitators of conducting such studies were the presence of supportive policies and regulations, collaborations between academia and industry, and the availability of skilled researchers. Moreover, the use of modeling techniques and the development of local pharmacoeconomic guidelines were suggested as potential solutions to overcome the identified barriers.

Cost−effectiveness of Landiolol, an Ultra−short−acting Betablocker, for Treatment of Sepsis Related Tachyarrhythmia in Germany

Günther Krumpl and Evelyn Walter*

Background: Sepsis and septic-shock are associated with cardiovascular problems, including tachyarrhythmia, myocardial injury, and changes in vascular endothelial function that might affect cardiac output with potential fatal outcome. The consequences of sepsis extend well beyond the acute illness. Tachycardia and new-onset atrial-fibrillation (AF), often treated with less effective agents such as amiodarone, are key prognostic factors for sepsis and associated with increased use of health-care resources and costs. Early decrease of heart-rate is associated with improved outcome. The use of β-blockers for managing acute arrhythmias in patients with septic-shock has been described in the literature. Landiolol, an ultra-short-acting β1-selective adrenergic-receptor-antagonist, is used specifically for the acute management of atrial-fibrillation and atrial-flutter in critically ill patients with/without cardiac-dysfunction.

Methods: A decision-model was developed to reflect the cost-effectiveness of landiolol in addition to conventional-therapy vs. standard-of-care (SoC) to manage sepsis-related tachyarrhythmia. The model combines a short-term decision tree to describe the time span of the sepsis related hospitalization over 28 days. The endpoint of the decision tree was then combined with a Markov model to simulate a life-long time horizon, as AF and post discharge mortality occurrence following sepsis hospitalization was more common among patients with new-onset AF during sepsis. The model calculates total costs (incl. hospital-stay, ICU and ventilation, AF costs) quality-adjusted life-years/QALYs and life-years/LYs over life-time.

Results: Manage sepsis related tachyarrhythmia with landiolol led to estimated lifetime costs of 59.130.79 € (95%-CI=53,436-64,901) per patient and 4.02 QALYs (5.56 LYs) over a life-time horizon. SOC was associated with 60.935.11 € (95%-CI=47,928-73,124) and 3.55 QALYs (5.01 LYs). Landiolol yields cost savings of about 1,804.31 € per patient and a QALY gain of 0.47 or 5.63 months in perfect health. Landiolol resulted in a life year gain of 0.54 LYs.

Conclusion: The economic analysis shows that the use of landiolol is associated with costs saving from the payer’s perspective.
