Until now, getting physicians to order medications electronically has been slow to take off. But a new merger between SureScripts and RxHub is expected to give the practice a shot in the arm. Hitherto rivals, SureScripts and RxHub have agreed to join forces under the new name of SureScripts-RxHub. As a result of this merger, physicians should be able to prescribe and obtain information on formularies and patient drug histories--all done electronically. The new entity is using the recruiter Spencer Stuart to search for a CEO. SureScripts was formed in 2001 by the National Association of Chain Drug Stores and the National Community Pharmacists Association, while RxHub, also established in 2001, is a joint venture of CVS Caremark Corp., Express Scripts, and Medco Health Solutions. The news of the merger comes in the wake of a recent proposal by the Drug Enforcement Administration that would allow the electronic ordering of controlled substances if safeguards are met.
