Recent reports show that at least 95% of the world's population is breathing polluted air. However, impact air quality on pollution-related medical expenditure and utilization sparse. This study estimates short-term health care cost impacts pollution using a meteorological phenomenon-thermal inversion-as an instrumental variable for quality. Using information outpatient respiratory diseases from universal insurance claim data in Taiwan during 2006-2012, our suggest one-unit reduction index...

Studies from other countries indicate that utilization patterns of antidiabetic drugs change significantly after the introduction newer classes (e.g. dipeptidyl peptidase-4 inhibitors [DPP-4i]). Evidence on recent trends regarding drug use in Taiwan is lacking, especially for times DPP-4i). Therefore, aim present study was to assess: (i) and spending drugs; (ii) changes (iii) factors associated with choice versus older drugs.Cases type 2 diabetes were derived Taiwan's National Health...

Low-molecular-weight organic acids (LMWOAs), a type of small molecules with one or more carboxyl groups present in soil, play an important role the soil ecosystem. Greenhouse could be as key example to understand LMWOA distribution and its ecological effects on heavy metals. In this study, 54 samples 24 vegetable were collected from Wuqing, Tianjin, China, investigate LMWOAs greenhouse effect transfer metals vegetables. The results showed that mean concentrations lactic acid, acetic formic...

This paper contributes to the growing body of literature that debates whether adoption pharmaceutical innovation increases overall expenditure on health care. By examining data obtained from Taiwan and focusing diabetic patients, we use a new class drugs, namely, thiazolidinediones, as an example investigate effect prescribing drugs patients by impact treatment substitution expansion. Overall, our results indicate introduction mainly impacts outpatient drug does not give rise any offsetting...

This study empirically examines the effect of hospital competition on prescribing behaviors oral hypoglycemic agents (OHAs) for ambulatory care in a market setting where hospitals are classified into three levels according to Taiwanese accreditation system. Without distinguishing types structures and levels, there might be no significant relationship between behavior. However, may differ among at various under each type structure. Our findings suggest that mechanism improve quality regional...

Abstract Promoting competition between brand-name and generic drugs has long been recognized as an approach adopted to save on health care costs. However, there are substantial variations in the extent of across countries. This study empirically estimates determinants market share Taiwan, where medical providers a position profit directly from sale prescription drugs. Our empirical results point out that profit-seeking behavior plays important dominant role behind pharmaceutical market. As...
