One in three prescriptions are now e-prescriptions in Massachusetts, according to e-prescribing network provider Surescripts last week at the annual Safe-Rx Awards ceremony in Washington, D.C.

The Alexandria, Va.-based Surescripts also announced that more than 200,000 office-based prescribers -- one out of every three physicians, nurse practitioners and physician assistants in the U.S. -- now uses e-prescribing.

According to Surescripts, the 10 states with highest rates of e-prescribing were:

1. Massachusetts
2. Michigan
3. Rhode Island
4. Delaware
5. North Carolina
6. Connecticut
7. Pennsylvania
8. Hawaii
9. Indiana
10. Florida

It was determined that prescribers in the Bay State sent more than 11 million prescriptions electronically in 2009, representing 32.3 percent of all prescriptions in the state, Surescripts stated.

In addition, e-prescribing is growing substantially across the U.S., according to Surescripts, citing that in 2009, 47 states more than doubled their use of prescription routing while 39 more than doubled their use of prescription benefit information.
