Development conceptual of pharmacoeconomic model of technology for early diagnosis and pharmacotherapy of pulmonary arterial hypertension

Abstract

Pulmonary arterial hypertension (PAH) is a rare, progressive disease with a poor prognosis in the absence of timely diagnosis and appropriate therapy. Despite significant advances in the treatment of PAH, many patients remain undiagnosed years after the onset of the disease. Evaluation of the implementation of early diagnostic technologies for PAH is increasingly being used to develop economic evidence for health care at the early stages of diagnosis. The development of models of early diagnosis technology for LAH is highly relevant and can be used in the development and management of new medical technologies, as well as to reduce the perceived risks during the implementation of screening programs for LAH diagnosis. The objective of the paper: Conceptual development of a pharmacoeconomic model of the technology of early diagnosis and pharmacotherapy of PAH. Our pharmacoeconomic analysis is based on the «cost–effectiveness» model, which reflects the effectiveness and associated costs of implementing diagnostic screening for early detection of patients with PAH. The analysis of input data of the existing health care system was conducted using systematic review, documentary, informational and graphical research methods. The presented pharmacoeconomic model describes not only the structure of the incidence of PAH in the studied risk group or at the level of the entire population, but also takes into account the pharmacoeconomic evaluation of the complex technology of timely medical care for patients with PAH based on diagnostic screening. A pharmacoeconomic model of the technology of early diagnosis and pharmacotherapy of pulmonary arterial hypertension was developed, which covered a horizon of 10 years and was conducted from the point of view of the existing health care system, showed that for patients with delayed diagnosis of PAH, the modeling determined the average life expectancy at the level of 4.13 years and 2.08 QALYs. It has been determined that a diagnostic screening strategy for PAH would be cost–effective compared to no screening at different thresholds of diagnostic cost. However, other factors such as public awareness and acceptance of the screening programme and availability of human resources should be considered.
