To realize clinical data exchange between healthcare providers, there must be many standards in many layers. Terms and codes should be standardized, syntax to wrap the data must be mutually parsable, then transfer protocol or exchange media should be agreed. Among many standards for the syntax, HL7 and DICOM are most successful. However, everything could not be handled by HL7 solely. DICOM is g...

Abstract While transnational social ties and exchanges are a core concern within migration studies, health researchers have often overlooked their importance. Continuous circular of information networks, also defined as remittances, facilitate the diffusion innovations, potentially driving contemporary cultural change. Influences on health, wellbeing, care-seeking important, but under-researche...

Recent healthcare reform has pointed out the excessive amount of redundancies and waste in US healthcare spending, in which duplicate testing is one contributing factor. In this research, we investigate the sources of waste in terms of duplication of radiology imaging tests when information sharing across providers are fragmented and patients may switch from one hospital to another throughout t...

In this paper I ask whether a central bank policy of providing liquidity to banks during panics can prevent bank runs without causing moral hazard. This kind of policy has been widely advocated, most notably by Bagehot (1873). To analyze such a policy, I build a model with three key features: 1) bank panics can occur in equilibrium, 2) there can be moral hazard, 3) the central bank can create m...

Programs to expand coverage, however, do not necessarily ensure seamlessness for many individuals who are likely to experience shifts in program eligibility d...

A successful exchange model provides a simple and intuitive front-end shopping experience for eligible consumers, a support module to promote broker and navigator usage, and a robust back-end system to integrate with issuers, state and federal agency systems. States must examine the following four important criteria: • Implementation cost. • Solution flexibility and interoperability. • Speed to...

health insurance “across state lines” are often promoted to address the challenges of high health insurance costs and a lack of choice among insurers and have been a core component of alternative health reform proposals since the mid-2000s. Critics, however, argue that across state lines proposals would lead to deregulation and a “race to the bottom” where health insurers relocate to the states...

Later this year, new provisions of the Patient Protection and Affordable Care Act of 2010 will transform the health care industry. Consumers will be able to purchase insurance through health insurance marketplaces, but many people who already have insurance could see their premiums rise. Insurers will need to help consumers navigate the new system.
