Medical errors are a serious issue that can have devastating consequences for patients and their families. While it is difficult to determine the exact number of deaths caused by medical errors, some studies estimate that over 200,000 patient deaths annually are due to preventable medical errors in the United States alone. This includes surgical errors, diagnostic errors, medication errors, equipment failures, and patient falls. These errors not only cause harm to patients but also negatively impact healthcare professionals, who may experience anger, guilt, and depression due to their mistakes. The high cost of medical errors, estimated at billions of dollars annually, further emphasizes the importance of improving patient safety and reducing errors in hospitals and other healthcare settings.

What You'll Learn
Misdiagnosis and diagnostic errors
Medical errors are a real concern, and people have died or been seriously injured due to errors in the healthcare system. While it is challenging to uncover the causes of these errors and provide solutions, it is important to recognise that they occur and can have severe consequences. Misdiagnosis and diagnostic errors are a significant subset of medical errors, and they can happen at any stage of the diagnostic process, from access and presentation to follow-up.
Diagnostic errors can have severe consequences for patients, ranging from no harm to severe harm or even death. A study by Schiff and colleagues (2009) defines diagnostic error as "any mistake or failure in the diagnostic process leading to a misdiagnosis, a missed diagnosis, or a delayed diagnosis." These errors can occur due to cognitive biases, system errors, or a combination of both. For example, cognitive forcing strategies (CFS) and reflection during the diagnostic process are techniques that can enhance metacognitive skills and improve diagnostic performance.
Diagnostic errors are an increasingly recognised threat to public health, with an estimated 5% of adults affected in outpatient settings. In hospital settings, diagnostic errors account for 6-17% of adverse events, and they are the most common reason for malpractice claims. The Institute of Medicine's report on diagnostic safety concluded that "most people will experience at least one diagnostic error in their lifetime."
To address diagnostic errors, it is essential to understand their causes and risks. The committee's approach to measurement proposes five purposes: establishing the incidence and nature of diagnostic errors, determining their causes and risks, evaluating interventions, education and training, and accountability. Autopsies, considered the "gold standard" for diagnosis, have seen declining rates, impacting the feedback clinicians receive on their diagnoses. Information technology has improved timely follow-ups on diagnostic tests, reducing delayed diagnoses, and structured protocols for telephone triage, teamwork, and communication training can also enhance diagnostic performance.
Additionally, health insurance claims databases offer opportunities to measure certain types of diagnostic errors, identify their clinical consequences and costs, and understand the factors associated with these errors. For instance, analyses of claims data could be used to identify the frequency of misdiagnosed acute coronary syndrome by exploring how often patients were seen before receiving the correct diagnosis.

Medication errors
Medical errors are a serious public health problem, and medication errors are a significant subset of these. While medication errors resulting in death are infrequent, they are a leading cause of injury and death.
While the exact number of deaths from medication errors is challenging to determine, studies have estimated that at least 44,000 Americans die in hospitals each year due to preventable medical errors, with the true number possibly being as high as 98,000. These numbers are based on extrapolations from studies conducted in New York, Colorado, and Utah, which found that the proportion of adverse events attributable to errors was 58% and 53%, respectively. Additionally, a recent study in Massachusetts found that 1% of hospital patients experienced preventable adverse events that were serious, life-threatening, or fatal. These studies indicate that medication errors are a significant issue that can have severe consequences for patients.
To reduce medication errors, healthcare professionals should be familiar with the different types of errors and their potential consequences. Encouraging the reporting of medical errors is essential to developing corrective measures and improving patient safety. By identifying the contributing factors and implementing prevention protocols, the incidence of medication errors can be reduced, improving patient outcomes and saving lives.

Surgical errors
The causes of surgical errors are often multifactorial, but common factors include miscommunication, unnecessary or emergency procedures, insufficient training, and provider burnout. Other factors include clinician issues (such as feeling rushed, distracted, or fatigued), changing or inadequate staffing, organisational problems, medical record-keeping issues, and cognitive errors.
To prevent surgical errors, several strategies have been developed. These include the implementation of checklists, counting instruments, using radio-frequency-marked sponges, and performing a surgical timeout. A surgical timeout involves pausing before the procedure to review the patient's identity, the consent form, the procedure, and the correct anatomical structures. Marking the correct surgical site, verifying the correct procedure and patient, and ensuring correct medication labelling are also crucial steps.

Patient falls
Falls are a significant issue, with an estimated 700,000 to 1 million hospitalized patients falling each year in the United States. The annual death rate from patient falls is 11,000, and between 30 and 51 percent of falls result in injuries. These injuries can be severe, including fractures and head trauma, and may even lead to death. The most common reasons for hospital falls include negligent nurses, nurse shortages, improperly trained staff, lack of communication among nursing staff, and an overall lack of a hospital safety culture.
To prevent patient falls, hospitals must conduct proper assessments to determine patients' fall risk. This includes considering factors such as a history of falling, medical conditions like past strokes or hip fractures, dizziness, lightheadedness, and the use of assistive devices. Additionally, medication side effects can increase the likelihood of falls, so a medication-induced fall risk assessment is crucial. Hospitals are required to implement and enforce fall risk precautions and have a written treatment plan to protect patients from falls.
Various strategies can be employed to reduce patient falls, such as staff education, patient mobility training, nutritionist support, identifying high-risk patients, providing patient safety companions, educating caregivers about fall prevention, and setting bed alarms for high-risk patients. However, it is important to balance fall prevention with other goals of hospitalization, especially for elderly patients who are at risk of losing mobility and functional status during their stay.
While patient falls can have serious consequences, they are preventable, and hospitals are responsible for implementing strategies to ensure patient safety and well-being.

Communication errors
While there is no precise data on the number of deaths caused by hospital errors, some studies indicate that over 200,000 people die annually in the United States due to preventable medical errors. Another study estimates that at least 251,454 people die each year in US hospitals from mistakes in care, accounting for a significant proportion of all hospital deaths.
Communication failures within hospitals can also cause delays in patient care, increase hospital stays, and negatively impact patient satisfaction scores. These issues may arise due to various factors, including ineffective policies and procedures, language barriers, poor communication skills, workload pressure, EHR issues, conflicts between staff members, and outdated communication technologies.
To address these issues, hospitals can implement modern clinical communication and collaboration (CC&C) platforms that integrate with EHRs and enable instant alerts. Additionally, hospitals can adopt communication strategies such as the RELATE model (Reassure, Explain, Listen/answer questions, Take action, Express appreciation), the STICC Protocol (Situation, Task, Intent, Concern, Calibrate), and the BATHE Protocol (Background, Affect, Troubles, Handling, Empathy). These strategies improve patient safety and ensure effective communication during shift handovers.
By utilizing modern communication platforms and implementing structured communication protocols, hospitals can significantly improve patient safety, reduce medical errors, and enhance overall patient care.

Frequently asked questions
It is estimated that anywhere between 44,000 to 400,000 people die from hospital errors in the US each year. However, some critics argue that these estimates are inflated and that the true number may be lower.
Hospital errors can include surgical errors, diagnostic errors, medication errors, equipment failures, and patient falls. Communication problems between medical professionals can also lead to errors, resulting in adverse events that cause harm to patients.
There are several reasons why it is challenging to determine the exact number of deaths caused by hospital errors. Firstly, studies may focus exclusively on hospitals and not on other parts of the healthcare system, such as clinics. Secondly, some errors may only have long-term effects that are difficult to trace back to the original error. Finally, there may be a culture of underreporting errors within the medical community due to concerns about confidentiality and liability, and blame.
