We study how delivery times and prices for hospital medical devices respond to the introduction of centralized procurement. Our identification strategy leverages a legislative change in Italy that mandated purchases sub-set devices. The statutory centralization generated reduction an increase relative non-centralized purchases. use data on quantities suppliers discuss mechanisms potentially und...

INTRODUCTION Extensively used polymers in biomedical applications are naturally occurring or synthetic compounds consisting of large molecules obtained from linking of simple monomers. Potential biomedical applications of these polymers include carrier based drug delivery systems, tissue engineering scaffold and cell culture supports [1]. Polymer based drug delivery system can control the rate ...

Background:  A significant increase in cesarean section in worldwide is known as one of the health system problems. The WHO has estimated that cesarean section in recent years has been 10% in all countries. Despite the increasing popularity of cesarean section, the literature lacks insights about factors affecting the selection of this delivery method. In this vein, this study investigates the ...
