Potential benefits and problems with computerized prescriber order entry: analysis of a voluntary medication error-reporting database.

PURPOSE: The potential benefits and problems associated with computerized prescriber-order-entry (CPOE) systems were studied. METHODS: A national voluntary medication error-reporting database, Medmarx, was used to compare facilities that had CPOE with those that did not have CPOE. The characteristics of medication errors reportedly caused by CPOE were explored, and the text descriptions of these errors were qualitatively analyzed. RESULTS: Facilities with CPOE reported fewer inpatient medication errors and more outpatient medication errors than facilities without CPOE, but the statistical significance of these differences could not be determined. Facilities with CPOE less frequently reported medication errors that reached patients (p < 0.01) or harmed patients (p < 0.01). More than 7000 CPOE-related medication errors were reported over seven months in 2003, and about 0.1% of them resulted in harm or adverse events. The most common CPOE errors were dosing errors (i.e., wrong dose, wrong dosage form, or extra dose). Both quantitative and qualitative analyses indicate that CPOE could lead to medication errors not only because of faulty computer interface, mis-communication with other systems, and lack of adequate decision support but also because of common human errors such as knowledge deficit, distractions, inexperience, and typing errors. CONCLUSION: A national, voluntary medication error-reporting database cannot be used to determine the effectiveness of a CPOE system in reducing medication errors because of the variability in the number of reports from different institutions. However, it may provide valuable information on the specific types of errors related to CPOE systems.

Medication errors involving wrong administration technique.

Wrong administration technique has consistently been one of the most harmful types of medication error in health systems participating in MEDMARX. Administration technique errors typically are made by nurses administering medications on the patient care unit, although errors in administration technique also occur in other phases of medication use and involve other health care personnel and locations. The most commonly reported causes of error have been performance deficit, failure to follow procedures or protocols, and knowledge deficit. Educating and training health care personnel on proper administration techniques and use of infusion pumps and dispensing devices could reduce the risk of error. The drug products most often associated with administration technique errors and patient harm could be targeted in staff education and training programs.

Medication errors related to product names.

Confusion arising from product naming practices can result in unauthorized drug and improper dose/quantity errors. Efforts by FDA, drug manufacturers, pharmacists, other health care professionals, and patients can reduce the risk of these errors.

Selected medication-error data from USP's MEDMARX program for 2002.

PURPOSE: Records from USP's MEDMARX database of medication errors for 2002 were studied. METHODS: Records of medication errors submitted to MEDMARX by participating health care institutions during 2002 were analyzed for error category index (whether a medication error actually occurred, whether it reached the patient, and, if so, the effect), node (the point in the medication-use process where the error occurred), type of error, cause, contributing factors, and drug products involved. RESULTS: The number of participating institutions was 482, and the number of medication error records released to MEDMARX was 192,477, an 82.2% increase from 2001. Errors that did not reach the patient were seen in 35% of the records, errors that reached the patient were seen in 49%, and errors that may have contributed to or resulted in harm were seen in 2%. The nodes, types of errors, causes of errors, contributing factors, and leading products by generic name are discussed. CONCLUSION: An analysis of over 192,000 records of medication errors submitted by nearly 500 health care facilities to USP's MEDMARX database in 2002 produced detailed information on the scope and nature of medication errors.

Medication errors: experience of the United States Pharmacopeia (USP) MEDMARX reporting system.

Medication errors are pervasive in America's health care system. MEDMARX is an Internet-accessible, anonymous medication error reporting program designed for hospitals and health systems to systematically collect, analyze, and report medication errors. This study examined 154,816 medication error reports that were submitted to MEDMARX between January 1, 1999, and December 31, 2001. Data fields analyzed were error category (based on the National Coordinating Council for Medication Error Reporting and Prevention's Error Category Index), type(s) of error, cause(s) of error, contributing factor(s), and product(s) involved. Approximately two-thirds of the errors reported reached the patient, with relatively few causing harm. Death was reported in 19 occurrences. Errors of omission and improper dose/quantity were the most commonly reported. Performance deficit and procedure/protocol not followed were consistently identified as causes of error. Distractions and workload increase were often cited as contributing factors. There was a similar pattern of products reported in each of the years. Implications for quality assurance, clinical practice, and health policy are presented.
