A recent article published in the Pharmacy Times, describes the astounding results of a study regarding the use of computerized provider order entry (CPOE) systems in hospitals. The study determined that as of 2008, the use of such systems has helped to avoid more than 17 million medication errors per year in hospitals nationwide so far.
According to the Institute of Medicine (IOM), hospitalized patients are subject on average to at least one medication error per day, which creates the potential for creating medical complications and lasting injury.
The researchers in the study estimated that as of 2008, around one third of all acute-care hospitals in the United States had begun using these types of systems, but only a little over half of them actually used them regularly. Based on that underlying presumption and other data the researchers collected, they estimated that as of 2008, around 26% of medication orders in acute-care hospitals were processed using the CPOE systems.
The computer systems are believed to reduce the chance of prescription medication error by 48%. Coupled with the degree to which CPOE systems have been adopted in hospitals nationwide, it is estimated that the use of the system has reduced the rate of medication errors by 12.5%. That means 17.4 million fewer medication errors throughout the United States in just one year.
There is a caveat however. The reduced number of errors does not necessarily correlate with less harm to the patient. Additionally, the implementation of the systems allows for new ways of making errors such as when a clinician selects either an incorrect medication or dosage from a pull down menu.
Even though the reduction in the errors was a welcomed achievement, the researchers noted that because there is not a universal use of these computer systems, there is much room for improvement to further reduce the widespread occurrence of medication errors.
