IntroductionIn Argentina, high-cost drugs (HCD) induce a high economic burden for all the health system sectors. However, it does not exist in Argentina any data that indicates the real problem of HCD for Social Security. That is why, the present study explores the economic impact of the HCD for one of the main Institutions of the country.MethodsA descriptive study with an analytical stage was carried out based on data obtained from management, pharmacy and accounting area. Each drug was classified according to WHO recommendation (Anatomical-Therapeutic-Chemical-ATC classification). The prices were expressed in three ways: nominal value at the time of acquisition in local currency, updated using the CER (reference stabilization coefficient), and in US dollars. A total of 105 324 HCD dispensed were evaluated, which corresponded to 258 011 units destined to 10 450 patients.ResultsTotal annualized spend was US$57 million (US$6220 per patient). Only 1.9% of affiliates required HCD, although those expenses represented 21.9% of the institutions' total income. The first 5 drugs associated to the highest expenditure were enzalutamide, bevacizumab, nivolumab, palbociclib, pembrolizumab. Oncological and rheumatological diseases represented 62.8% of the HCD costs.ConclusionConsidering the results obtained, it can be deduced that if the HCD problem is approached in a scattered way by each subsector, it will become a potential risk for health system defund. The HCD topic requires of global policies at national or even regional level.
