BACKGROUND: Medication errors are preventable events that can cause or lead to inappropriate drug use. Knowing the prevalence and types of errors can help us institute corrective measures and avoid adverse drug events.
OBJECTIVE: This study determined the prevalence of medication errors and its specific types in the four main service wards of a tertiary government training medical center.
METHODS: This is a retrospective, descriptive chart review study. From the master list of admissions, systematic sampling was done to retrieve the required number of charts. Relevant pages such as order sheets, nurses' notes, therapeutic sheets were photographed. For prolonged admissions, only the first 7 days were reviewed. Each chart was evaluated by two people who then met and agreed on the errors identified.
RESULTS: The overall prevalence of medication errors is 97.8%. Pediatrics had the most (63.3/chart), followed by Medicine, OB-Gynecology, and Surgery (7.3/chart). The most common type of errors identified were prescribing, followed by compliance, then administration errors.
CONCLUSION: Medication errors are present in the four main wards in our hospital. We recommend orientation of all incoming first year residents on proper ordering and prescribing of drugs, as well as a prospective observational study to determine true prevalence of all types of medication errors.

Medication Errors

INTRODUCTIONMedication discrepancies and poor documentation of medication changes (e.g. lack of justification for medication change) in physician discharge summaries can lead to preventable medication errors and adverse outcomes. This study aimed to identify and characterise discrepancies between preadmission and discharge medication lists, to identify associated risk factors, and in cases of intentional medication discrepancies, to determine the adequacy of the physician discharge summaries in documenting reasons for the changes.

METHODSA retrospective clinical record review of 150 consecutive elderly patients was done to estimate the number of medication discrepancies between preadmission and discharge medication lists. The two lists were compared for discrepancies (addition, omission or duplication of medications, and/or a change in dosage, frequency or formulation of medication). The patients' clinical records and physician discharge summaries were reviewed to determine whether the discrepancies found were intentional or unintentional. Physician discharge summaries were reviewed to determine if the physicians endorsed and documented reasons for all intentional medication changes.

RESULTSA total of 279 medication discrepancies were identified, of which 42 were unintentional medication discrepancies (35 were related to omission/addition of a medication and seven were related to a change in medication dosage/frequency) and 237 were documented intentional discrepancies. Omission of the baseline medication was the most common unintentional discrepancy. No reasons were provided in the physician discharge summaries for 54 (22.8%) of the intentional discrepancies.

CONCLUSIONUnintentional medication discrepancies are a common occurrence at hospital discharge. Physician discharge summaries often do not have adequate information on the reasons for medication changes.

Wrong-route or -patient medication errors due to human mistakes have been considered difficult to resolve in clinical settings. In this study, we suggest a safety injection system that can help to prevent an injection when a mismatch exists between the drug and route or patient. For this, we prepared two distinct adapters with key and keyhole patterns specifically assigned to a pair of drug and route or patient. When connected to a syringe tip and its counterpart, a catheter injection-port, respectively, the adapters allowed for a seamless connection only with their matching patterns. In this study, each of the adapters possessed a specific key and keyhole pattern at one end and the other end was shaped to be a universal fit for syringe tips or catheter injection-ports in clinical use. With the scheme proposed herein, we could generate 27,000 patterns, depending on the location and shape of the key tooth in the adapters. With a rapid prototyping technique, multiple distinct pairs of adapters could be prepared in a relatively short period of time and thus, we envision that a specific adapter pair can be produced on-site after patient hospitalization, much like patient identification barcodes.

OBJECTIVE: To identify the technical considerations in implementing a barcode-based medication system and propose practical solutions for successful implementation of the system. In order to reduce medical errors related to medication and blood transfusion, we analyze various factors that hinder the successful implementation of the barcode-based medication system and discuss issues involved in the effective adoption of such a system. METHODS: The barcode-based medication system of this research uses one-dimensional, barcode bands on patients' wrists and two-dimensional barcodes attached to drug bags and blood bags. PDAs with barcode reading capability and wireless networking function are used, which enables Point of Care. The business process for applying the developed system and the current status of the system usage are analyzed. RESULTS: The factors causing a variety of system failures in the demonstration and pilot periods were identified and categorized as including PDA malfunction, PDA battery discharge due to users' carelessness, confusion in reading barcodes and so on. CONCLUSIONS: It is expected that the analyzed obstructive factors and the proposed technical considerations addressed in this paper can help other hospitals implement similar barcode-based medication systems successfully. Ultimately, this research will contribute to reducing medical errors and improving quality of patient care.

BACKGROUND: Pro re nata (PRN) prescription is a frequently used prescription method in hospitals. This study was conducted to investigate actual condition of PRN prescription and whether administration error occurred because of perception difference between doctors and nurses. METHODS: From May to July 2012, a survey was conducted among 746 doctors and nurses (88 doctors and 658 nurses) working at 5 hospitals located in Seoul, Gyeong-gi, and Gangwon Province. Doctors generating PRN prescription responded to actual conditions of PRN prescription and both doctors and nurses reported whether administration error occurred due to perception difference. RESULTS: Average number of PRN prescription of surgical residents was 4.6 +/- 5.4, which was larger than that of medical residents (1.7 +/- 1.0). Surgical residents more frequently recorded maximum number of daily intake (P = 0.034) and, although not statistically significant, more often wrote exact single dosage (P = 0.053) and maximum dosage per day (P = 0.333) than medical residents. Doctors expected nurses to notify them before the administration of medication; however, nurses were more likely to conduct PRN administration by their own decision without informing doctors. In addition, some doctors and nurses experienced administration errors because of it. CONCLUSION: Standard prescription methods need to be established since there is a perception difference in PRN prescription between doctors and nurses and this could be related to administration errors.

PURPOSE: This study was carried out to investigate perception and experience of medication errors by nurses. METHOD: Data collection through a survey was performed using structured questionnaires over the period of September 1 to October 15, 2004. Questionnaire were delivered to 222 nurses from 15 hospitals; thereafter, 205 questionnaires were responded (i.e., 92% response rate). The subject in the study was a nurse who had been working in the hospital for less than one year. RESULTS: The average perception rate was 87.5%. The perception rates of subjects in medication errors from four areas are 62% in wrong dosage form for drug administration, 61.5% in air into an IV set, 63% in crystals in an IV lines, and 83.5% in wrong time. The experience rates of subjects in medication errors from four areas are 85.5% in wrong time, 39.5% in wrong injection site, 34.5% in omission error, and 28% in wrong patient. CONCLUSION: The average perception rate and experience rates of medication errors were 87.5% and 23.5%, respectively. Education about the Five right in medication and knowledges about drugs would improve the perception of medication errors of nurses whose work experience is less than one year, and prevent them from medication errors.

PURPOSE: This study was done to investigate nurses' perceived importance of, and performance of intravenous fluid therapy. METHODS: Data were collected from a convenience sample of 234 nurses (return rate: 93%) working in 3 small-medium general hospitals. RESULTS: The score for perceived importance of intravenous fluid therapy (3.65+/-0.37) was higher than that of performance (3.45+/-0.39). There were positive correlations between perceived importance and performance (r=.576, p<.001). There were 180 (80.8%) errors in intravenous fluid therapy. Perceived importance and performance scores were higher in nurses who had not experienced medication errors in intravenous fluid therapy. CONCLUSION: The results indicate a need to develop appropriate strategies to improve perceived importance and performance and enhance safety management during intravenous fluid therapy for nurses in small-medium general hospitals.

Medication errors such as administration of wrong drugs, wrong dosage and erroneous route of administration are not rare among medical misadventures. We present an autopsy case of accidental injection of tranexamic acid instead of bupivacaine during spinal anesthesia, accompanying the quantitative result of the tranexamic acid in the blood, cerebrospinal fluid and each internal organs. We think that warning signs on syringes and ampoules, simple and unified guideline for drug administration, separative documentation of drug administration and interpersonal communication on drug information should be done to prevent this type of medical errors.

PURPOSE: The emergency department is prone to medical errors due to the patients'acuity and complexity. Collection and monitoring of data on medical errors are essential for setting priorities and improving patient safety. METHODS: Emergency physicians report medical errors voluntarily with an intranet-based error reporting system. The system is confidential and anonymous. Data on medical errors was collected at the emergency department of a tertiary teaching hospital with approximately 76,000 annual visits, during a nine-month period from April to December 2008. The collected data was analyzed prospectively. RESULTS: Of the 238 reports collected, 204 errors were analyzed. 90.6% of the errors were related to doctors and 21% were related to nurses. Error types were classified into clinical errors (57%), medication errors (7%) and administrative errors (35%). The levels of impact on patients caused by these errors were classified as near-miss in 28 (13%), no harm in 93 (45%), mild harm in 66 (32%), lethal in 5 (2%) and death in 2 (1%) cases. Errors that occurred in the elderly group (over 60 years of age) had more harmful impact than in other age groups (p=0.0003). The causes of these errors were human in 147 (72%), systems in 23 (11%) and both human and systems in 34 (17%). Most of these errors were preventable (99%). CONCLUSION: Data collected by the intranet-based medical error reporting system is useful to classify and analyze medical errors, and is also essential in the implementation of a patient safety system.
