National study on the frequency, types, causes, and consequences of voluntarily reported emergency department medication errors

Background: Medication errors contribute to significant morbidity, mortality, and costs to the health system. Little is known about the characteristics of Emergency Department (ED) medication errors. Study Objective: To examine the frequency, types, causes, and consequences of voluntarily reported ED medication errors in the United States. Methods: A cross-sectional study of all ED errors reported to the MEDMARX system between 2000 and 2004. MEDMARX is an anonymous, confidential, de-identified, Internet-accessible medication error-reporting program designed to allow hospitals to report, track, and share error data in a standardized format. Results: There were 13,932 medication errors from 496 EDs analyzed. The error rate was 78 reports per 100,000 visits. Physicians were responsible for 24% of errors, nurses for 54%. Errors most commonly occurred in the administration phase (36%). The most common type of error was improper dose/quantity (18%). Leading causes were not following procedure/protocol (17%), and poor communication (11%), whereas contributing factors were distractions (7.5%), emergency situations (4.1%), and workload increase (3.4%). Computerized provider order entry caused 2.5% of errors. Harm resulted in 3% of errors. Actions taken as a result of the error included informing the staff member who committed the error (26%), enhancing communication (26%), and providing additional training (12%). Patients or family members were notified about medication errors 2.7% of the time. Conclusion: ED medication errors may be a result of the acute, crowded, and fast-paced nature of care. Further research is needed to identify interventions to reduce these risks and evaluate the effectiveness of these interventions.     

An observational study of drug administration errors in a Malaysian hospital (study of drug administration errors)

Background and objective: Drug administration errors were the second most frequent type of medication errors, after prescribing errors but the latter were often intercepted hence, administration errors were more probably to reach the patients. Therefore, this study was conducted to determine the frequency and types of drug administration errors in a Malaysian hospital ward. Methods: This is a prospective study that involved direct, undisguised observations of drug administrations in a hospital ward. A researcher was stationed in the ward under study for 15 days to observe all drug administrations which were recorded in a data collection form and then compared with the drugs prescribed for the patient. Results: A total of 1118 opportunities for errors were observed and 127 administrations had errors. This gave an error rate of 11·4 % [95% confidence interval (CI) 9·5–13·3]. If incorrect time errors were excluded, the error rate reduced to 8·7% (95% CI 7·1–10·4). The most common types of drug administration errors were incorrect time (25·2%), followed by incorrect technique of administration (16·3%) and unauthorized drug errors (14·1%). In terms of clinical significance, 10·4% of the administration errors were considered as potentially life‐threatening. Intravenous routes were more likely to be associated with an administration error than oral routes (21·3% vs. 7·9%, P < 0·001). Conclusion: The study indicates that the frequency of drug administration errors in developing countries such as Malaysia is similar to that in the developed countries. Incorrect time errors were also the most common type of drug administration errors. A non‐punitive system of reporting medication errors should be established to encourage more information to be documented so that risk management protocol could be developed and implemented.     

Emergency department medication lists are not accurate

Background: Medication errors are a common source of adverse events. Errors in the home medication list may impact care in the Emergency Department (ED), the hospital, and the home. Medication reconciliation, a Joint Commission requirement, begins with an accurate home medication list. Objective: To evaluate the accuracy of the ED home medication list. Methods: Prospective, observational study of patients aged > 64 years admitted to the hospital. After obtaining informed consent, a home medication list was compiled by research staff after consultation with the patient, their family and, when appropriate, their pharmacy and primary care doctor. This home medication list was not available to ED staff and was not placed in the ED chart. ED records were then reviewed by a physician, blinded to the research-generated home medication list, using a standardized data sheet to record the ED list of medications. The research-generated home medication list was compared to the standard medication list and the number of omissions, duplications, and dosing errors was determined. Results: There were 98 patients enrolled in the study; 56% (55/98, 95% confidence interval [CI] 46–66%) of the medication lists for these patients had an omission and 80% (78/98, 95% CI 70–87%) had a dosing or frequency error; 87% of ED medication lists had at least one error (85/98, 95% CI 78–93%). Conclusion: Our findings now add the ED to the list of other areas within health care with inaccurate medication lists. Strategies are needed that support ED providers in obtaining and communicating accurate and complete medication histories.
