Medication errors during medical emergencies in a large, tertiary care, academic medical center

Purpose

Evaluate the rate, type and severity of medication errors occurring during Medical Emergency Team (MET) care at a large, tertiary-care, academic medical center.

Methods

A prospective, observational evaluation of 50 patients that required MET care was conducted. Data on medication use were collected using a direct-observation method whereby an observer documented drug information such as drug, dose, frequency, rate of administration and administration technique. Subsequently, a team of three clinicians assessed rate, type and severity of medication errors using definitions consistent with United States Pharmacopeia MEDMARX system. Severity was assessed on a scale of minor, moderate and severe.

Results

One hundred eighty six doses were observed for 36 different medications. A total of 296 errors were identified; of these 196 errors (66%) were inappropriate aseptic technique. Of the remaining 100 errors, 46% were prescribing errors, 28% administration technique errors, 14% mislabeling errors, 10% drug preparation errors and 2% improper dose prescribing. Examples included: (1) prescribing errors, (2) administering wrong doses, (3) mislabeling, and (4) wrong administration technique such as not flushing intravenous medication through intravenous access. The rate of medication administration errors was 1.6 errors/dose including aseptic technique and 0.5 errors/dose excluding aseptic technique. A notable portion (14%) of errors was considered at least moderate in severity.

Conclusions

One out of 2 doses was administered in error after errors of using inappropriate aseptic technique were excluded. There is a need for education and systematic changes to prevent medication errors during medical emergencies as an effort to avoid harm.

Nurses' perceptions of how physical environment affects medication errors in acute care settings

The work that nurses perform in hospital environments is physically and psychologically intense, with the potential for burnout and stress. This issue is compounded by crowded and poorly designed work spaces in nursing units that can contribute to medical mistakes, including medication errors. This article is based on a study that examined the nurses' perception of how the physical environment in hospitals affects medication errors. Literature suggests that reduction of staff stress can be achieved through physical environmental considerations, such as improved air quality, acoustics, and lighting. However, there is no empirical study specifically exploring the relationship between aspects of the physical environment and medication errors. In this study, a cross-sectional survey was conducted with nursing staff (N = 84) in four hospitals in the Pacific Northwest region of the United States. The survey included questions on nursing unit design, medication room configurations, perceived incidence of errors, and adverse events. Respondents noted several physical environmental factors that are potentially problematic in the nursing station area and can lead to medication, documentation, and other types of nursing errors. These factors include inadequate space in charting and documentation area, lengthy walking distances to patient rooms, insufficient patient surveillance opportunity/lack of visibility to all parts of the nursing unit, small size of the medication room, inappropriate organization of medical supplies, high noise levels in nursing unit, poor lighting, and lack of privacy in the nursing stations. As administrators in acute care facilities consider strategies for organizational and staff interventions to reduce medication errors, it is important to consider physical environmental factors to have a comprehensive understanding of the issue.     

Medication errors: protecting both patient and provider

Administering the right medication in the right dose via the right route to the right patient is essential to quality patient care. Providers must be educated on all related policies and periodically reviewed. In addition, providers must take personal responsibility to assure knowledge and ability to determine the correct medication in any given scenario and calculate the correct dose. EMS administrators, employers, providers and medical directors must work together to identify system problems and establish policies and procedures for efficient and effective prevention of medication errors. Until next time, be safe!.     

Medication errors: professional issues and concerns

In the UK, medication errors are a growing problem. Dobrzanski et al (2002) estimated that in one trust the incidence of medication error ranged between 35 to 70 per cent. Such high estimations are a cause for concern, particularly when the administration and supply of medicines, which directly involves nurses, can contribute to the cause of medication error. Part of the National Patient Safety Agency's (NPSA) role is monitoring medication errors in hospitals. Although the NPSA can provide information on drug alerts that target primary care organisations, obtaining accurate figures for medication errors is more difficult. Medication errors can be extremely harmful for older people, therefore nurses who prescribe or administer medicines should be assessed for mathematical competence, but also be aware of the potential problems that can arise from medication errors (Banning 2005).     

Non-health care facility medication errors resulting in serious medical outcomes

Objective: The objective of this study is to provide an epidemiologic analysis of medication errors occurring outside of health care facilities that result in serious medical outcomes (defined by the National Poison Database System as “moderate effect,” “major effect,” “death,” or “death, indirect report”).

Methods: National Poison Database System data from 2000 through 2012 were used for this retrospective analysis of non-health care facility medication errors.

Results: From 2000 through 2012, Poison Control Centers in the United States received data on 67,603 exposures related to unintentional therapeutic pharmaceutical errors that occurred outside of health care facilities that resulted in serious medical outcomes. The overall average rate of these medication errors was 1.73 per 100,000 population, and there was a 100.0% rate increase during the 13-year study period. Medication error frequency and rates increased for all age groups except children younger than 6 years of age. Medical outcome was most commonly reported as moderate effect (93.5%), followed by major effect (5.8%) and death (0.6%). Common types of medication errors included incorrect dose, taking or administering the wrong medication, and inadvertently taking the medication twice. The medication categories most frequently associated with serious outcomes were cardiovascular drugs (20.6%) (primarily beta blockers, calcium antagonists, and clonidine), analgesics (12.0%) (most often opioids and acetaminophen, alone and combination products), and hormones/hormone antagonists (11.0%) (in particular, insulin, and sulfonylurea).

Conclusions: This study analyzed non-health care facility medication errors resulting in serious medical outcomes. The rate of non-health care facility medication errors resulting in serious medical outcomes is increasing, and additional efforts are needed to prevent these errors.     

Intravenous medication errors in the emergency department,knowledge, tendency to make errors and affecting factors: An observational study

BackgroundIntravenous medication errors are common in hospital settings particularly emergency department. This study aimed to determine intravenous medication preparation and administration errors, contributing factors, tendency towards making errors and knowledge level of emergency department healthcare workers.MethodsA cross-sectional study using a structured, direct observation method was conducted. It was conducted with 23 emergency healthcare workers working in the emergency department of a university hospital in Turkey. Data were collected by questionnaires: Knowledge Test on Intravenous Medication Administration, Intravenous Drug Administration Standard Observation Form, Drug and Transfusion Administration Sub-Dimension scale, Perceived Stress Scale and Pittsburgh Sleep Quality Index.ResultsIt was determined that the knowledge level of the emergency healthcare workers about intravenous medication administration was moderate, and the tendency mistakes regarding drug and transfusion applications was very low. There was no relationship between education level, years of work, years of work in the emergency department, perceived stress level and sleep quality, and the tendency of making mistakes in drug and transfusion applications.ConclusionIt is important for patient safety to prevent medication errors by determining the factors affecting intravenous medication administration, tendency to make mistakes and knowledge levels, which are frequently used in emergency department.     

Medication errors in emergency rooms, intensive care units and pediatric wards

Medication safety is a major concern worldwide that directly relates to patient care quality and safety. Reducing medication error incidents is a critical medication safety issue. This literature review article summarizes medication error issues related specifically to three hospital units, namely emergency rooms (ERs), intensive care units (ICUs), and pediatric wards. Time constrains, lack of patient history details and the frequent need to use rapid response life-saving medications are key factors behind high ER medication error rates. Patient hypo-responsiveness, complex medication administration and frequent need to use high-alert medications are key factors behind high ICU medication error rates. Medication error in pediatric wards are often linked to errors made by nurses in calculating dosage based on patient body weight. This article summarizes the major types of medication errors reported by these three units in order to increase nurse awareness of medication errors and further encourage nurses to apply proper standard operational procedures to medication administration.     

Medication errors in the emergency department: a systems approach to minimizing risk

Adverse drug events caused by medication errors represent a common cause of patient injury in the practice of medicine. Many medication errors are preventable and hence particularly tragic when they occur, often with serious consequences. The enormous increase in the number of available drugs on the market makes it all but impossible for physicians, nurses, and pharmacists to possess the knowledge base necessary for fail-safe medication practice. Indeed, the greatest single systemic factor associated with medication errors is a deficiency in the knowledge requisite to the safe use of drugs. It is vital that physicians, nurses, and pharmacists have at their immediate disposal up-to-date drug references. Patients presenting for care in EDs are usually unfamiliar to their EPs and nurses, and the unique patient factors affecting medication response and toxicity are obscured. An appropriate history, physical examination, and diagnostic workup will assist EPs, nurses, and pharmacists in selecting the safest and most optimum therapeutic regimen for each patient. EDs deliver care "24/7" and are open when valuable information resources, such as hospital pharmacists and previously treating physicians, may not be available for consultation. A systems approach to the complex problem of medication errors will help emergency clinicians eliminate preventable adverse drug events and achieve a goal of a zero-defects system, in which medication errors are a thing of the past. New developments in information technology and the advent of electronic medical records with computerized physician order entry, ward-based clinical pharmacists, and standardized bar codes promise substantial reductions in the incidence of medication errors and adverse drug events. ED patients expect and deserve nothing less than the safest possible emergency medicine service.     

Medication administration errors in adult patients in the ICU

OBJECTIVE: To quantify the incidence and specify the types of medication administration errors from a list of error-prone medications and to determine if patient harm resulted from these errors. DESIGN: An observational evaluation. SETTING: Five intensive care units (ICUs) in the United States. PATIENTS AND PARTICIPANTS: Eight hundred fifty-one patients who were at least 18 years of age and admitted to surgical, medical or mixed ICUs during a 3 month period were included. INTERVENTIONS: None. MEASUREMENTS AND RESULTS: A list of error-prone medications was adapted from the literature and evaluated for medication errors and patient harm. Of 5,744 observations in 851 patients, 187 (3.3%) medication administration errors were detected. the therapeutic classes most commonly associated with errors were vasoactive drugs 61 (32.6%) and sedative/analgesics 48 (25.7%). The most common type of error was wrong infusion rate with 71 (40.1%) errors. Twenty-one errors did not reach the patient and 159 reached the patient but did not result in harm, increased monitoring or intervention. Five errors required increased patient monitoring and two required intervention. None of the errors resulted in patient death. CONCLUSIONS: This multicenter evaluation found fewer medication administration errors than the published literature, possibly due to the varying observational techniques and pharmacist involvement. Lorazepam and wrong infusion rates are associated with errors that occurred frequently, resulted in the greatest potential for harm and were common oversights in the system. These errors should be considered potential areas for betterment in the medication use process to improve patient safety.     

Medication errors: ethical implications

Errors in health care are receiving much attention today, although committing such errors is not a new phenomenon. Nurses are taught procedures so that they are less likely to make mistakes. Yet nurses do make errors. Although many types of errors can and do occur in the health care setting, this article focuses on a discussion of medication errors and related ethical implications. Several ethical issues may arise as a result of medication errors: harm to patients, whether to disclose the error, erosion of trust, and impact on quality care. Nurses' appropriate ethical responses to medication errors need to be supported. Changing the health care system will help nurses to promote patient welfare, lessen the chance of harm, and reduce the likelihood of medication errors occurring.     

Medication administration errors and the pediatric population: a systematic search of the literature

Medication administration errors are a serious concern for the pediatric population. This article presented an overview of medication errors and safe medication administration practices. Additional information was presented regarding the pediatric population and specific factors that make this population susceptible to medication errors. A systematic literature search on medication administration errors in the pediatric population was presented. From the search, five themes emerged, including the incidence rate of medication administration errors, specific medications involved in medication administration errors and classification of the errors, why medication administration errors occur, medication error reporting, and interventions to reduce medication errors.Differences in study design made it difficult to compare the articles with regard to some of the themes. However, it was apparent that medication administration errors do occur in the pediatric population, regardless of the exact incidence rate. As previously stated, the NCC MERP believes that there is no acceptable incidence rate for medication errors. Errors in dosage were found to be a common reason as to why medication errors occur. There was some discrepancy with regard to medication error reporting, as it was found that medication errors are underreported, but the extent of this varied. Systems used to report medication errors also varied. It was found that the more detailed the information reported on the medication error, the more potential impact it had on leading to a system change to prevent such errors from occurring again. It is recommended that reporting systems be nonpunitive so that nurses are not afraid to report errors. In addition, more emphasis should be placed on near miss medication errors, as these occur frequently but are rarely reported and may provide greater insight into system flaws. Lastly, interventions found to reduce medication administration errors were congruent with current recommendations for safe medication administration. This calls into question if the current recommendations are being followed uniformly. Implications for future research and practice include that a formalized system check for safe medication administration be developed and utilized. System checks have been developed and are widely used during the prescribing and preparing stage, and less medication errors are noted during this early part of the medication process. Having a formalized system check during medication administration would aid in ensuring that current recommendations are being followed, which would lead to a decrease in medication administration errors.Parents and caregivers naturally expect that their children will be safe when in the health care system. Yet, providing health care will always involve some degree of risk due to both the complexity of the health care environment and the role that human judgment plays within it. Nurses play a role in improving the safety of children within their care. The role of the nurse is much wider than simply reporting patient safety incidents or near misses; it includes taking preventative actions, sharing experiences, learning from mistakes, and helping to devise solutions.
