The use of computerized physician order entry (CPOE) is growing and is currently utilized in about 10% of U.S. Hospitals.22 When linked with clinical decision support, it provides a unique and important tool to improve ordering decisions, thereby reducing medication errors, transcribing errors, decreasing the frequency of adverse drug events, and increasing compliance with evidence-based clinical guidelines.23 This leads to overall improved patient care. There is growing recognition of the importance and utility of CPOE technology, and currently, there is a concerted effort nation-wide to implement it in all hospitals and private practices. CPOE programs provide an excellent platform to increase the implementation of clinical practice guidelines, thereby changing physician behavior.
