Statistical evidence of medical errors serves as a reminder of the significant challenges facing healthcare systems and patients worldwide. A recent report from the Institute for Healthcare Improvement estimated that medical errors contribute to more than 250,000 deaths in the United States annually, making them a leading cause of mortality (5).  

Medical errors also result in substantial economic burdens. For example, a study published in Health Affairs estimated that medical errors cost the United States healthcare system $19.5 billion annually in extra healthcare spending (13). These costs encompass prolonged hospitalizations, additional treatments, legal expenses, and lost productivity.  

These statistics underscore the urgent need for comprehensive efforts to enhance patient safety, address the root causes of medical errors, and equip healthcare professionals with the knowledge and strategies necessary to prevent these costly and potentially fatal mistakes. 

Impact of Medical Errors 

Medical errors have far-reaching and profound consequences in American healthcare and globally, affecting patients, healthcare providers, and healthcare systems. These errors can result in serious harm, extended hospital stays, and even death, imposing immense physical and emotional burdens on patients and their families.  

For instance, a medication dosage error may lead to adverse drug reactions, prolonged hospitalization, and extensive medical costs. Beyond the individual level, medical errors strain healthcare resources and budgets, leading to increased healthcare expenditures and litigation costs for healthcare organizations. A recent report by (14), highlighted that healthcare-associated infections alone, often exacerbated by medical errors, cost the U.S. healthcare system billions of dollars annually (SHEA, 2020).  

Furthermore, medical errors erode public trust in healthcare institutions, hindering the delivery of effective care and undermining the overall quality of healthcare. Addressing medical errors is not only a moral imperative but also a financial and public health necessity to ensure safe and efficient healthcare delivery.

Medical errors have a wide-ranging impact on patients, often resulting in a spectrum of injuries that can vary from minor complications to severe and life-threatening consequences.  

Some examples of injuries caused by medical errors include the following:  

• Injuries caused by medication errors: Patients may receive the incorrect drug, dosage, or route of administration. For example, a patient on a prescribed medication for hypertension might mistakenly receive a medication intended for a different condition, leading to adverse drug reactions, allergic responses, or, in extreme cases, fatal overdoses (2).  
• Injuries caused by surgical errors: Surgical errors represent a significant risk, encompassing scenarios like wrong-site surgeries or the retention of surgical instruments within a patient's body. In the event of a wrong-site surgery or retention of surgical instruments within a patient’s body, a patient may undergo an additional surgery or unnecessary procedure, leading to complications, extended hospital stays, and long-term physical and emotional repercussions (9). 

• Injuries caused by diagnostic errors: Diagnostic errors, such as misdiagnoses or delayed diagnoses, present another facet of medical errors. These errors can have profound consequences as they may lead to patients receiving inappropriate treatments or experiencing disease progression due to the delay in receiving the correct diagnosis. For instance, a delayed cancer diagnosis might result in the cancer advancing to a more advanced and less treatable stage (4).  
• Injuries caused by lapses in infection control measures within healthcare settings: These lapses can contribute to hospital-acquired infections, resulting in complications, prolonged hospitalization, and increased healthcare costs (18). 
• Psychological injuries: Beyond the physical harm, medical errors can also inflict psychological injuries, with patients and their families often experiencing anxiety, post-traumatic stress disorder, or other emotional distress, especially in cases involving severe harm or near misses.  

These different types of injuries underscore the complex and far-reaching impact of medical errors on patients' physical and emotional well-being, emphasizing the critical need for comprehensive strategies to prevent the errors causing them. 

How Medical Errors Can Cause Death 

Medical errors can tragically lead to patient deaths through several pathways, each emphasizing the dire consequences of possible systemic failures within healthcare systems.  

Let’s discuss some examples below.  

• One of the most pervasive types of medical errors that can cause death is medication errors, where patients may inadvertently receive the wrong drug or an incorrect dosage. Such errors can result in fatal overdoses or severe adverse reactions, contributing to patient fatalities (8). For instance, administering a medication intended for another patient with a similar name can lead to grave consequences, highlighting the critical importance of medication safety measures. 
• Surgical errors represent another alarming category, encompassing scenarios like wrong-site surgeries or complications during procedures. In cases of wrong-site surgery, patients may undergo unnecessary procedures, while complications can lead to severe infections or life-threatening hemorrhages. These errors can result in fatal infections or excessive blood loss, ultimately contributing to patient deaths (10).  
• Diagnostic errors, where conditions are misdiagnosed or diagnosed too late, pose additional challenges. These errors can lead to treatment delays, allowing diseases to progress unchecked and reach an advanced, untreatable stage, further underscoring the significance of accurate and timely diagnosis in patient outcomes (4).  

• Lastly, lapses in infection control practices can lead to healthcare-associated infections, potentially culminating in sepsis and organ failure, with the dire consequence of patient deaths (18).  

These examples collectively emphasize the imperative of enhancing patient safety and mitigating medical errors to prevent the diverse ways in which they can tragically lead to the loss of life. 

Cost of Medical Errors 

The link between medical errors and the cost of healthcare is a substantial and concerning issue. Medical errors lead to significant financial burdens on healthcare systems, patients, and society at large. For example, a study published in Health Affairs estimated that medical errors in the United States cost an astonishing $19.5 billion annually in extra healthcare spending (13).  

These costs encompass a range of factors, including extended hospital stays, additional medical procedures to address complications, and increased medication and treatment expenses. Moreover, medical errors can result in costly litigation, settlements, and insurance premiums for healthcare organizations.  

In addition to direct costs, indirect costs such as lost productivity due to disabilities resulting from medical errors can further inflate the economic toll. These findings underscore that addressing medical errors is not only crucial for patient safety but also for reducing the financial strain on healthcare systems and individuals. 

Types of Medical Errors 

There are several types of medical errors, with each one carrying the potential to harm patients in distinct ways.

Examples of bedside strategies that not only enhance patient safety but also empower healthcare providers to actively engage in error prevention at the point of care include the following:  

• Using transparent and purposeful "time-out" procedures before surgical interventions, where the entire surgical team pauses to verify the patient's identity, procedure, and surgical site, to help prevent wrong-site surgeries (12).  
•  Using effective barcode scanning technology at the bedside to confirm the accuracy of medication administration, ensuring that patients receive the correct medications and dosages.  

• Using thorough handoffs during nursing shift changes to allow for direct communication between nurses, reducing the risk of information gaps and miscommunication.  
• Implementing medication reconciliation protocols by thoroughly reviewing a patient's medication history and comparing it to the prescribed medications at the bedside, to identify discrepancies and prevent potential medication errors. For instance, if a patient mentions taking a medication that is not listed in their current prescription, this can trigger a thorough investigation to avoid drug interactions or duplications that could lead to adverse effects. Research by (11), highlights the significance of medication reconciliation in reducing medication errors and enhancing patient safety at the bedside. 
• Using efficient patient identifiers, such as wristbands and two-factor identification, to prevent wrong-patient errors. In scenarios where patients share similar names or medical records, verifying the patient's identity before administering treatments or procedures is critical. For example, before administering medications, nurses can cross-reference the patient's identification wristband with the medication order, ensuring that the right patient receives the right medication and dosage. Studies, like the one by (7), emphasize the effectiveness of patient identification strategies in preventing wrong-patient errors and the potential harm they can cause. 

Organizational Strategies
