Medication Errors: A Common Hospital Concern?

Medication errors are a widespread issue in hospitals, with the FDA receiving over 100,000 reports of such incidents annually in the United States alone. These errors can lead to around 400,000 drug-related injuries in hospitals each year and are the most common preventable cause of patient injury. They can occur due to various factors, including human error, inadequate knowledge, poor coordination, and communication breakdowns. Older patients are more likely to be affected due to their increased medication needs, and certain medications, such as intravenous antibiotics, are more prone to errors. While technology has been instrumental in reducing errors, human factors and system flaws continue to play a role in their occurrence.

Medication errors are the most common cause of patient injury

Medication errors are the most common and preventable cause of patient injury in hospitals. These errors can occur at any healthcare facility, including hospitals, clinics, pharmacies, and patients' homes. They are often a result of administering the wrong drug, an incorrect dose, or using the wrong method. The reported incidence of medication errors in acute hospitals is approximately 6.5 per 100 admissions, with almost one in five medication doses given during hospital stays being in error.

Several factors contribute to an increased risk of medication errors, including older age, an overburdened healthcare system, multiple prescribed drugs, and multiple prescribers for a single patient. These errors have adverse consequences, such as drug-drug interactions, prolonged hospital stays, and heightened patient mortality risk. Globally, medication errors are responsible for 5% to 41.3% of hospital admissions, with approximately 400,000 drug-related injuries occurring in hospitals annually.

To reduce medication errors, hospitals can implement distraction-free zones during medication administration and use technology such as smart infusion pumps with Dose Error Reduction Software (DERS). Computerized medication order entry has shown a reduction in errors, with some studies reporting a decrease of at least 50%. Additionally, medication reconciliation, which involves documenting a definitive list of prescribed medications, can help prevent errors and improve patient safety.

Communication breakdowns are another leading cause of medication errors. Verbal or written miscommunication between physicians, nurses, healthcare team members, or patients can result in medical errors. To address this, healthcare providers can utilize electronic medical records to identify potential drug interactions and calculate dosages. Furthermore, the Joint Commission has made medication safety a National Patient Safety Goal, emphasizing the importance of preventing medication errors and improving patient outcomes.

Intravenous antibiotics are the drugs most associated with errors

Medication errors are a significant concern in hospitals, and intravenous antibiotics are the drugs most associated with these errors. Intravenous administrations carry a higher risk and severity of errors than other medication administrations. A study of 107 nurses preparing and administering 568 intravenous medications across six wards in two teaching hospitals found that nearly 70% of these intravenous administrations had at least one clinical error, and a quarter of these were serious errors that could cause permanent harm to patients.

Several factors contribute to the high error rate in intravenous antibiotic administration. One factor is skill and knowledge deficiencies among nurses, as errors and severity decrease with greater clinical experience. Procedural failures, such as checking patient identification, and clinical errors, such as incorrect intravenous administration rates, are common. Other errors include incorrect volume and drug incompatibility. These errors can have severe consequences, including permanent harm or even death.

The risk of medication errors is also influenced by factors such as older patient age, an overburdened healthcare system, a high number of prescribed drugs, comorbidities, and multiple prescribers for a single patient. In addition, interruptions during medication administration and preparation have been associated with procedural failures, clinical errors, and compromised patient safety. These interruptions can be minimized by implementing a "do not disturb" protocol for nurses, which has been shown to reduce interruptions and improve patient safety.

To reduce errors in intravenous antibiotic administration, hospitals can optimize their workflow to minimize interruptions and implement distraction-free zones during medication administration. Additionally, utilizing automated medication dispensing systems and medicine packaging can reduce the time required for medication preparation and administration. Implementing computerized medication order entry systems, as suggested by the World Health Organization (WHO), can also significantly reduce medication errors, with some studies reporting a decrease of at least 50%.

Furthermore, addressing knowledge gaps and providing adequate training for healthcare staff can help prevent errors related to skill and knowledge deficiencies. Standardization of procedures, proper documentation, and effective coordination of medication orders during transfer of care are also essential in reducing medication errors. By implementing these measures, hospitals can improve patient safety and reduce the risk of harm associated with intravenous antibiotic administration.

Interruptions during medication administration increase errors

Medication errors are the most common preventable cause of patient injury in hospitals. These errors include administering the wrong drug, an incorrect dose, using the wrong route, or giving medication to the wrong patient. Globally, medication errors account for 5% to 41.3% of hospital admissions, with one in seven Medicare patients in hospitals falling victim to a medical error.

Interruptions during medication administration have been identified as a significant cause of these errors, leading to procedural failures and compromised patient safety. Distractions during the prescribing or administration process can result from poor writing, misunderstood symbols or abbreviations, or improper translation. Illegible handwriting has long been a challenge in healthcare, with the Institute of Safe Medication Practices recommending the elimination of handwritten orders and prescriptions.

To minimize interruptions and reduce errors, a distraction-free period and zone should be implemented during medication administration. While this may not always be feasible in critical care or hospital settings, a "do not disturb" intervention has proven effective in reducing interruptions. Such an intervention involves minimizing non-medication-related interruptions, such as phone calls or conversations, to ensure a nurse's undivided attention during the administration process.

Additionally, optimizing nursing workflow is crucial. Automated medication dispensing systems and medicine packaging can reduce the time nurses spend on medication administration and decrease the need for preparation at the patient's bedside. Computerized medication order entry systems have also been shown to reduce medication errors by up to 50%, with the added benefit of clinical decision-support systems and alerts for high-risk medications.

By addressing interruptions and optimizing workflows, hospitals can significantly reduce medication errors, enhance patient safety, and improve overall healthcare standards.

Poor communication and coordination cause medication errors

Medication errors are the most common cause of patient injury and are preventable in most cases. They are also the third-leading cause of death in the US. Globally, medication-related errors account for 5% to 41.3% of hospital admissions.

Poor communication and coordination are significant causes of medication errors. Communication breakdowns can occur between physicians, nurses, healthcare team members, or patients. Verbal or written communication failures can lead to medication errors, with adverse outcomes such as decreased adherence to treatment, patient dissatisfaction, and inefficient use of resources.

Effective physician-patient communication is vital for favourable health outcomes, including increased patient satisfaction, compliance, and overall health status. For example, a 2008 study by Bartlett G et al. concluded that communication problems with patients led to increased adverse preventable effects, mostly drug-related. Similarly, a 40-year-old man with ileo-caecal tuberculosis failed to take his prescribed anti-tubercular therapy due to poor communication and presented with features of disseminated tuberculosis after taking only prednisolone for two weeks.

Communication breakdowns can also occur among healthcare providers. A study by the Joint Commission found that 80% of serious medical errors resulted from miscommunication between caregivers during patient handovers. Inaccurate, incomplete, or ambiguous information during shift changes increases the probability of medical mistakes.

Coordination issues can also lead to medication errors. Poor coordination of medication orders during the transfer of care can cause human errors. For instance, poor documentation and labelling of specimens may occur. Additionally, inadequate patient education can lead to medication errors, especially if patients find their medication regimens confusing or complicated.

To reduce medication errors, hospitals have adopted platforms that support text messages, audio and video calls, and instant alerts. These platforms improve patient safety, reduce medical errors, increase productivity, and significantly cut costs.

Adverse drug events are common in all settings of care

Adverse drug events (ADEs) are one of the most common preventable adverse events in all settings of care. They are caused by the widespread use of prescription and non-prescription medications, with clinicians having access to more than 10,000 prescription medications. Nearly one-third of adults in the United States take five or more medications, and polypharmacy (taking more medications than clinically necessary) is the strongest risk factor for ADEs. ADEs account for nearly 700,000 emergency department visits and 100,000 hospitalizations each year.

The medication-use process is complex, with many steps and risk points for error. Medication errors typically involve administering the wrong drug, an incorrect dose, using the wrong route, or giving medication to the wrong patient. These errors can occur due to human factors, impaired safety culture, or system flaws. Older adults are particularly vulnerable to ADEs as they tend to take more medications and are more susceptible to specific medication adverse effects. Pediatric patients are also at higher risk, especially when hospitalized, as medication doses for children are often weight-dependent.

Several factors increase the risk of medication errors, including older age, an overburdened healthcare system, multiple prescribed drugs, comorbidities, and multiple prescribers for a single patient. Inadequate staffing, while not a direct cause, can put healthcare workers in situations where they are more likely to make mistakes. Interruptions during medication administration and preparation have been associated with procedural failures, clinical errors, and compromised patient safety.

Medication errors can be prevented through various means. Computerized medication order entry systems have shown a reduction in medication errors, with some studies reporting a decrease of at least 50%. Clinical decision support systems and alerts can further decrease error rates, especially for high-risk medications. Additionally, medication review and reconciliation, which involves documenting a definitive list of a patient's medications, can help reduce errors, especially in hospitals. Implementing "do not interrupt" interventions for nurses during medication administration has also been found to reduce interruptions.
