The dramatic growth in health expenditures is an important health policy concern worldwide. Therefore, understanding the factors that increase health expenditures provides policy makers with evidence for decision-making. We aim to examine long-term effects of carbon dioxide emission, urbanization rate and GDP per capita on health expenditures. This study investigates the effect of carbon dioxide emission, urban population, and GDP per capita on health expenditure for 21 OECD countries over the period 1992–2018. Panel ARDL Approach and Gengenbach, Urbain and Westerlund Panel Co-integration Test have been used in the article. Test results indicate the long-run relationship among health expenditure and carbon dioxide emission, urban population, and GDP per capita. Effect of carbon dioxide emission (CO2), urban population, and GDP per capita is significant and positive on health expenditure. Rapid economic growths of OECD countries recently and environmental pollution have increased health expenditures in the long term. [ABSTRACT FROM AUTHOR]

The Substance Abuse and Mental Health Services Administration's (SAMHSA) National Registry of Evidence-based Programs and Practices (NREPP) is an online database of mental health and substance- abuse interventions that have undergone an independent review process to rate their quality of research and readiness for dissemination. Originally conceived as a U.S.-based national registry, NREPP has effectively become an international resource on evidence-based programs and practices, containing information on interventions from around the world and drawing an international audience. The objectives of this descriptive study were to determine how many interventions in the registry (1) have been implemented outside the United States, (2) have materials translated into one or more languages, (3) have received funding from a non-U.S. source, and (4) have been evaluated in studies conducted outside the United States. The growing interest in other countries for tools to assist in the identification and implementation of evidence-based programs suggests that NREPP will become increasingly relevant and useful to international mental health constituencies.
