Abstract 367: Comparison of the Healthcare Systems of the United States and Portugal: Epidemiology and Management of Coronary Heart Disease

Abstract

Objectives: Adoption of health technologies may yield significant individual and societal benefits. Because different healthcare systems vary in their adoption speeds, an understanding of the underlying healthcare system is critical. We compared the United States (US) and Portugal (PT) healthcare systems focusing on coronary heart disease (CHD). CHD remains one of the main causes of death in high-income countries with significant economic costs. Methods: We conducted a comprehensive literature review based on publications from national governmental bodies, international institutional organizations, professional associations, and scientific journals. We abstracted information regarding risk factors, incidence, access to health technologies, and hospital mortality rates in CHD observed between 2000 and 2011. Findings: The prevalence of obesity and high cholesterol levels is higher in the US while higher rates of hypertension and tobacco consumption prevail in PT. The 2009 incidence of cardiovascular disease per 100000 population in the US is 1944.5 versus 1320.4 in PT. The percentage of total health expenditure financed through public funds is 48.2% in the US versus 65.8% in PT. Public hospitals represent 26% (1526 of 5754) of US hospitals and 55% (129 of 231) of hospitals in PT. Between 2000 and 2011, the average high-risk device approval time was 43 months quicker in the European Union (EU) compared to the US. Drug-eluting stents were approved in 2002 in the EU and in PT versus 2003 in the US. Speeds of approval for pharmaceuticals vary – prasugrel, and ticagrelor were approved 5 and 8 months faster in PT compared to the US but PT approval of glycoprotein IIb/IIIa inhibitors was slower (18 months slower on average). However, US CHD standardized mortality is more than twice that of PT (126.5 vs 59.4 per 100000). Conclusions: Procedure and new technology use differ dramatically between the two healthcare systems for CHD care. Portugal offers an interesting contrast to the US for studies focusing on health technologies adoption, diffusion, cost-effectiveness and determinants of outcomes in the realm of CHD. How these factors directly impact patient outcomes remains unknown and deserves further investigation.
