Healthcare: E-Prescribing

What is E-Prescribing?
In general, E-prescribing is an electronic way to send an accurate, error-free and understandable prescription directly to a pharmacy from the point-of-care. It’s been described as the solution to improve patient safety and reducing sky-rocketing medication costs.

Adoption History
Based on HIMSS source, 7,000 Americans die and 1.5 million Americans are injured yearly and the cost of errors is $2 billion per year. Physicians write more than 4.5 billion prescriptions each year. Only 20% of prescriptions are prescribed electronically; 80% are handwritten.

On November 7, 2005, Medicare and Medicaid Service (CMS) published foundation standard of e-prescribing under Part D of the MMA.

On January, 1, 2006, the standards became effective.

On April, 2, 2008, the final e-prescribing rule was released by the Federal Register.

Beginning January 1, 2009, CMS will offer physician payment incentives of 2 percent for using e-prescribing in 2009 and 2010.

After May 2009, MMA will result in greater support for e-prescribing. But this does not mean that e-prescribing is required and will become the most common approach. And Most information about e-prescribing can be obtained from

Healthcare Information and Management System Society (HIMSS) http://www.himss.org/ASP/index.asp

E-Prescribing in China
HL7 China was formed in 2006, and e-prescribing has been adopted widely in major cities, e.g., Shanghai, Beijing. 90% of the grade-three hospitals has adopted e-prescribing systems based on the news. http://www.hl7china.com.cn/.

In this merging market, lots of software vendors are there already. Most of them just started a couple of years ago. Recently I spent lots of time thinking about what still can be done and debating with a physician from a different way of thinking. I would not post a lot of details technically, but basically I think that there are lots of new development opportunities we can do with e-prescribing. There is no winner yet. The best product with the right business model, right execution, right persons, high quality will win in the end.

Web 3.0

The definition of Web 3.0 is difficult to be precise. Especially there is no clear boundary between and Web 2.0 and Web 3.0. “Web 3.0 Emerging” by Jim Handler, IEEE Computer, Jan 2009 is a good article of articulating what Web 3.0 technologies cover.

Web 3.0 extends current Web 2.0 applications using semantic web technologies and graph-based open data. Web 3.0 establishes relationships among data elements from the same or different distributed web 2.0 applications. Web 3.0 integrates data elements to produce new mashups and combined applications.


The resource description framework (RDF), SPARQL query language (a SQL-like standard for querying RDF data) and the web ontology language (OWL) are the basic technologies used by Web 3.0 applications to link or integrate, mashup data from multiple websites or databases. But early Web 3.0 applications may not use RDF and OWL directly.

As we know, some successful and dominant Web 2.0 applications are Flickr, Wikipedia, Facebook, MySpace and YouTube. And the merging Web 3.0 applications are Metaweb, Powerset, Radar Networks and more.
