Abstract

The Price-Volume Agreement (PVA) is a system that adjusts prices of pharmaceuticals when utilization quantities increase, and is expected to play a key role in managing pharmaceutical spending by National Health Insurance (NHI). However, the current system needs some improvement to meet the changing environment. In this study, various PVA revision senarios were developed using the 2015-2017 PVA results and NHI pharmaceuticals claims data, and the budget impact by each senario was analyzed. During the 3 years, total 112 medicines’ prices were reduced by 4.6% as a results of PVA. As the main factors for the revision scenarios, ‘Exclusion criteria’ to select the medicines included to PVA and ‘price reduction rate’ were developed and conjugated. As a results, total 16 scenarios were selected for the budget impact analysis. As a result of simulating the budget impact when these are applied, the maximum savings of over 100 billion won in 2017 was estimated. PVA is a system with great potential in post-market management of drug costs. Not only can the drug cost be contained, but the role of pharmaceutical spending management by government can be expanded through the efficient operation of the system. Through the scenario developed in this study, it is expected that this system can maximize its role and increase its effectiveness.
