Description

Computerized provider order entry (CPOE), sometimes referred to as electronic prescribing, is a computer application that health care providers use to enter orders or prescriptions into a computer system. It is used in inpatient and outpatient settings to electronically order medications, imaging studies, laboratory tests, procedures, admissions, and referrals (AHRQ-Dixon 2009). CPOE can be integrated with electronic health records (EHRs) or a standalone electronic interface, and is often combined with computerized clinical decision support systems (CDSS). CPOE increases the legibility and completeness of prescriptions and orders and reduces transcription errors by reducing or eliminating hand written prescriptions (Abramson 2012).

Expected Beneficial Outcomes

Reduced medication errors
Reduced adverse drug events
Improved patient safety
Increased adherence to clinical guidelines

Evidence of Effectiveness

There is strong evidence that computerized provider order entry (CPOE) reduces medication error rates (Kukreti 2014, Nuckols 2014, Georgiou 2013, Radley 2013, Maslove 2011, Eslami 2008, van Rosse 2008, Kaushal 2003). In some cases, it may also decrease adverse drug events (ADEs) (Nuckols 2014, Eslami 2008). Additional evidence is needed to confirm effects on ADEs.

CPOE decreases medication error rates in a variety of settings, including hospital settings (Nuckols 2014, Eslami 2008) such as pediatric (van Rosse 2008) and intensive care units (Maslove 2011, van Rosse 2008) and emergency departments (Georgiou 2013), though effectiveness may depend on the quality of the implementation process (van Rosse 2008). Overall, it appears to reduce chemotherapy medication error rates in outpatient settings, though some specific errors may increase (Kukreti 2014). CPOE decreases test volume and reduces the cost of pathology services (Georgiou 2007). It also appears to increase patient safety and provider adherence to guidelines (Eslami 2008).

CPOE combined with clinical decision support systems (CDSS) reduces medication prescribing errors (Ranji 2014, Stultz 2012, Schedlbauer 2009) and may also reduce adverse drug events (Stultz 2012, Wolfstadt 2008). Such systems can also improve medication management by increasing accuracy and improving record keeping (AHRQ-McKibbon 2011). Medication dosing advice within CPOE can improve some patient outcomes (Cochrane-Gillaizeau 2013, Sahota 2011) and increase physician compliance with care guidelines (Tawadrous 2011, Jamal 2009, Georgiou 2007).

Frequent CDSS alerts when prescribing lead to “alert fatigue” and may cause prescribers to miss or ignore important alerts (Stultz 2012, Moxey 2010, Eslami 2008). Prioritizing reminders with the greatest potential effects on patient safety might improve provider acceptance of higher level alerts (Eslami 2008).

Implementing CPOE, particularly with CDSS, can profoundly change workflows. Workflow changes may present new safety issues (Ranji 2014, AHRQ-Dixon 2009) and have the potential to introduce new errors (Maslove 2011, Eslami 2008).

Implementation

United States

Computerized provider order entry is required for meaningful use through the federal Medicare and Medicaid Electronic Health Records Incentive Programs (US DHHS-Meaningful use).
