ABSTRACT 

This literature review aims to highlight the overview of medication errors and strategies to avoid 

and decrease medication errors. Availability of various types of over-the-counter and prescribed 

medication has added to the risk of medication. Also, the medication chain has different steps, and 

different people are involved in each step, such as prescribing medication, dispensing, and 

administering medication. Every phase in the medication chain is prone to risks that can lead to 

medication errors. Medication safety is the responsibility of every healthcare professional 

involved in the medication chain to deliver effective and safe care to patients with an optimal 

outcome. A medication error can happen in every health care setting to decrease and prevent 

medication errors. It is critically important to have complete knowledge of the medication use 

chain and integrate evidence-based strategies, such as medication reconciliation, analysis of 

medication error, double-check, and avoiding interruption and distraction into practice. 

Medication errors can lead to patient harm, prevent on-time discharges, and increase care costs. 

Medication safety culture can shine in a setting of effectively applying strategy into practice, and 

everyone's collaboration and commitment to adhere to medication safety strategy can improve 

patient safety.  

 

Keywords: Reconciliation, Analysis, Medication Error, Strategy. 

 

INTRODUCTION 

Medication Error Overview and Prevention Strategies  

Healthcare expenses in the United States are approximately $3.5 trillion annually. The United 

States of America consumes more money per person in healthcare than other developed countries 

(CDC, 2021). A significant portion of healthcare costs is related to medication prices.  In 2016, 

almost $450 billion was spent on therapeutic medication. Over time, the medication costs are 

presumed to increase (Aitken & Kleinrock, 2017).  

           One of the primary missions of a healthcare professional is to deliver safe and effective care 

to the patient to reach optimal outcomes. Fostering evidence-based practices and safe use of 

medication is vital to high-quality and effective care (Carayon et al., 2020; Musharyanti et al., 

2019). Medication errors happen in every health facility globally, and they can cause severe 

consequences for patients. 

           Error in medicine is not one hundred percent avoidable, and it constitutes a significant threat 

to patient safety (Bonney, 2013). One of the most prevalent medical errors that healthcare 

professionals and patients can encounter is medication error. It constitutes 10 to 18 percent of 

overall medical errors in healthcare settings (Sarhadi et al., 2015).

           A medication error can occur at any phase of the medication chain. For example, a 

medication error can happen during writing a prescription, dispensing, or administering the 

medication. Studies indicate most medication errors (87%) happen when the medication is 

administered to the patient. The majority of medication errors at this step medication process are 

nursing related (Yousefi et al., 2014).  

           The financial and non-financial implications of medication error on the health system are 

critical. A medication error can prolong hospital stays and increase the cost of healthcare services. 

The financial burden of avoidable medication errors is approximately $2 billion annually in the 

United States of America (Eslami, 2007). 

           Expansion in the variety of medications has increased the complexity of medication 

administration and the prescription process. There are over 10,000 types of prescription medication 

in 300,000 types of products available over the counter in the United States (Anderson & Aspeden, 

2007). Approximately 5% of patients experience an adverse event from a medication side effect 

or an error during their stay in the hospital (Pelletier & Beaudin, 2018). 

 

Definition 

Medication error does not have a universal definition. The concept of medication error might vary 

from country to country based on differing local laws.  In the U.S., the National Coordinating 

Council for Medication Error Reporting and Prevention has defined medication error as:  

"Any preventable event that may cause or lead to inappropriate medication use or patient 

harm while the medication is in the control of the health care professional, patient, or 

consumer. Such events may be related to professional practice, health care products, 

procedures, and systems, including prescribing, order communication, product labeling, 

packaging, and nomenclature, compounding, dispensing, distribution, administration, 

education, monitoring, and use." (NCCMERP, 2021). 

 

Medication Error Strategies 

It is essential to develop strategies to decrease the risk of medication errors in the medication 

delivery chains. Healthcare personnel has applied evidence-based strategies into practice to reduce 

and prevent the possibility of medication errors in healthcare settings. 

 

Analysis of Medication Error Events 

Reporting a medication error is a critically important asset to limit medication error instances and 

create strategies to prevent further medication errors (Kohn, 1999). Notwithstanding the thorough 

impact these errors have on the healthcare system, they extensively go under-reported, mainly due 

to the fear of backlash (Zhan et al., 2008). 

          When medication error happens, it has to be considered as a learning opportunity to improve 

care and reduce the chance of the same medication error in the future. When the hospital takes 

punitive actions against staff who make the medication error, it can lead to the demoralization of 

other staff to report medication errors (Pelletier & Beaudin, 2018).  

           It is critically important to report medication errors to develop countermeasures in order to 

radically remove the occurrence of the same medication or reduce their impact. Significant causes 

of medication error are system-related rather than human-related factors (Rex et al., 2000). Some 

healthcare facilities have noticed success in enhancing the process and decreasing the medication 

errors via Lean Six Sigma methodology (De Koning et al., 2006).

Double Check 

Nuclear power, aviation, and other high-risk industries have a history of using double checks and 

triple checks to ensure that crucial processes are carried out correctly. Thankfully, most healthcare 

facilities now have incorporated chemotherapy and other high-risk medication (Neuss et al., 2016).  

          Moreover, in healthcare facilities where a double check is a requirement, it is also crucial to 

apply it into practice. Otherwise, it is straightforward for the second check to become lackadaisical, 

contributing to false reassurance in a state of genuinely increasing patient safety (Pelletier & 

Beaudin, 2018). 

 

Avoiding Distractions and Interruption Factors 

Every step, in medication administration, processing, prescribing, and preparation is prone to 

medication errors. Even though most healthcare facilities have applied automated systems for the 

medication delivery steps, humans are still involved in every step of medication delivery. For 

example, there is a computerized system for the dosage of the medication. Still, a doctor needs to 

add the medication dose into the system. 

          Recent studies indicate that disruption and interruptions can increase the possibility of 

medication error in the medication delivery steps (Hayes et al., 2015). At the same time, studies 

indicate that reducing or removing distractions and interruption can increase medication safety 

(Prakash et al., 2014).  

          On the other hand, some argue that specific interruptions are critical to delivering high-

quality, effective, and safe care to the patient (Rivera-Rodriguez & Karsh, 2010). A systematic 

review in 2014 showed that decreasing interruption during medication administration did not show 

strong evidence to support the prevention interruption and distraction strategy (Raban & 

Westbrook, 2014).  

 

Medication Reconciliation 

The chance of medication error is significantly high when the patient is transitioning from one 

service to another service, for example, when a patient is transferred from ICU to a regular ward 

or a patient is transferred from a primary doctor to a specialist. Studies indicate that unintended 

medication inconsistency is common, happening in 30% of patients when the patient is admitted 

to the hospital or transferred from one service to another. Moreover, it causes moderate to severe 

harm in 40% of patients (Bishop et al., 2015).  

           Medication reconciliation is a practice to review a patient medication list on both sides of 

care transition in an attempt to prevent unplanned discrepancies (Rose et al., 2017).  

While studies are commencing to indicate some preeminent practices in medication 

reconciliation, uncertainty regarding what functions still floats over, and successful studies 

indicate beneficial impacts on adverse drug events compared to actual patient harm (Kwan et al., 

2013). 

CONCLUSION 

The growth of available medication has increased drug side effects and errors that threaten patient 

safety. Medication errors can happen at any stage of the medication chain, especially during 

prescription and administration steps. It is essential to assure the staff to report medication errors 

without punitive consequences. Reporting medication errors is the correct key to find the causes 

and solutions to prevent future errors.  Several healthcare facilities are equipped with a 

computerized system that can be helpful to prevent medication errors. In addition to technology, 

we need to apply medication safety policies into the practice and encourage staff to stay compliant

with the practices. Moreover, we need more research to illustrate strategies and solutions to 

medication errors to safely provide practical, high-quality care to the patient.
