Computerized physician order entry (CPOE) is a technology that allows physicians to enter orders, medications, or procedures directly into the computer instead of handwriting them. [1] [2] The electronic medical system transmits the order to the appropriate department or individual so the order can be carried out. [3]

Computerized physician order entry
CPOE History
In 1971, Lockheed Martin developed the first CPOE system in the El Camino hospital in Mountain View, California. The system was rudimentary, withalmost no clinical decision support (no alerts, automatic calculations, or suggestions), but it did allow physicians to quickly order medications with a few simple clicks.
Despite the reported success of the medical information system in El Camino Hospital[5], others were slow to follow. In 1984, the Regenstrief Institute implemente a CPOE at Wishard Memorial Hospital. This system required keyboard input, but had more decision support than the El Camino system. It allowed automatic reordering and alerts for known adverse interactions. In 1988, the LDS Hospital in Salt Lake came out with HELP, a blood-product-specific CPOE system that added an additional "standing orders" feature, which automatically placed orders for specific procedures that were added over time. [4]
From 1994 to 2004, commercial CPOE grew quickly. Cerner came out with Millenium, Eclipsys changed their E7000 line into SCM, Siemens launched InVision, Meditech announced Magic, EpicCare was released, McKesson developed Horizon, and GE was just finishing Centricity. [5] However, as of 2009, less than 10% of the hospitals in the US had fully operational CPOE systems. [6]

System Configuration
The system should be configured correctly for ease of use and security.
- Passwords should be secure yet easy to remember. [7]
- Co-signatures allows for multiple levels of function and security (eg, an RN can place an order but only with a signature from a physician)
- Time-out settings prevent accidental unauthorized access.
- Clinical staff are sometimes reluctant to switch from paper to electronics. Active encouragement, additional training, and a deadline to fully integrate into CPOE increases compliance.

Some organizations hire computer scribes who follow and enter orders for physicians. This allows reluctant physicians to also comply with CPOE.

Handheld Computers
While handheld computers are good replacements for small reference books and interactive guides, they are unlikely to be significantly used in an integrated clinical record system. The interface is small and difficult to enter data into, security is more easily compromised, and wireless connections are slower than their Ethernet counterparts. [8]
Infection Control Concerns
There is considerable evidence and discussion of the keyboard as a source of pathogens; particularly the antibiotic resistant Methcillin Resistant Staph Aureus (MRSA) and Vancomycin Resistant Enterococcus (VRE). [9] MRSA may reside on medical surfaces for days to weeks. [10] Multiple precautions can be take to reduce transmission of infection. Physicians and nurses should be educated to the risks posed by the keyboard. Housekeeping staff should have keyboard cleaning techniques added the daily cleaning rounds. Standard housekeeping operating procedure should include cleaning keyboard surfaces every shift (every 8 hours) or at least every 12 hours.
