Ambulatory Computerized Provider Order Entry (ACPOE or E-Prescribing)

Part of the Health Informatics book series (HI)


Medical errors arise in part from variations in clinical care. Two broad sources of variations in care are: (a) the progressive complexity of health care (providers caring for more patients with multiple and/or chronic medical needs, less time in which to see them, fragmentation and lack of coordination of care) and (b) barriers (internal and external) that practitioners face in adhering to evidence-based treatment guidelines.1–3

Since the 1970s, patient safety has embraced computerized order entry (among other technologies) as a way to reduce medication errors and improve guideline compliance. Order entry for medication delivery to patients has been studied extensively.4–13
