Hospitals are complex institutions where the health and lives of patients are at stake. Medical errors can have severe consequences, including increased patient harm, deaths, and higher healthcare costs. Common errors include surgical mistakes, diagnostic errors, medication errors, equipment failures, patient falls, hospital-acquired infections, and communication breakdowns. These issues can affect not only patients but also their families, healthcare professionals, and the wider community. Preventing errors requires a culture of safety, improved communication, and the use of strategies like checklists and error reporting systems. Additionally, addressing sleep deprivation and implementing sterile cockpit procedures can help minimise distractions and enhance patient safety. The active involvement of patients in their care is also essential, as is the reporting of near misses and adverse events to identify system vulnerabilities. Ultimately, reducing errors in hospitals is critical to improving patient outcomes and maintaining trust in the healthcare system.

What You'll Learn
Medical errors are a serious public health problem
Medical errors can occur anywhere in the healthcare system, including hospitals, clinics, surgery centers, doctors' offices, nursing homes, pharmacies, and patients' homes. Common types of medical errors include surgical errors, diagnostic errors, medication errors, equipment failures, patient falls, hospital-acquired infections, and communication failures. For example, medication-related harm affects one out of every 30 patients in healthcare, with more than a quarter of these cases considered severe or life-threatening.
Errors in surgery also have severe consequences, with intraoperative errors estimated to be the primary issue in 75% of malpractice cases involving surgeons. Surgical errors involving the wrong site, patient, or procedure should never occur, yet they persist due to factors such as clinician distractions, miscommunication, and inadequate staffing.
Communication breakdowns are the most common cause of medical errors. Verbal or written communication issues can occur between physicians, nurses, healthcare team members, or patients. Inadequate information flow can lead to problems such as a lack of crucial information when making prescribing decisions. Other factors contributing to medical errors include system and process failures, economic and financial pressures, and challenges related to the natural environment.
To reduce medical errors, it is essential to implement strategies such as staff education, eliciting staff advice, and budget appropriations to improve internal reporting and disclosure systems. Root cause analysis (RCA) is another tool used to identify the factors contributing to adverse events and develop improvement action plans. Additionally, reporting near misses, or incidents where harm to the patient was narrowly avoided, can provide invaluable information for proactively reducing errors and improving patient safety.

Medication errors can be prevented by using safety protocols
Medical errors are a leading cause of death and injury, with medication errors being the most common preventable cause of patient injury. In the US, it is estimated that 7,000 to 9,000 patients die from medication errors annually, with many more suffering adverse reactions or worsened medical conditions. These errors can also have severe consequences for healthcare professionals, including emotional distress, damage to their professional reputation, and legal consequences.
Medication errors typically involve administering the wrong drug or dose, using the wrong route, administering it incorrectly, or giving medication to the wrong patient. To prevent these errors, hospitals should implement safety protocols and a culture of safety that encourages reporting and addresses errors without a blame culture.
One safety protocol is to optimize the workflow to minimize interruptions during medication preparation and administration. This can be achieved through the use of automated medication dispensing systems and medicine packaging, which reduce the time needed for medication administration and decrease the risk of interruptions leading to errors. Implementing a "do not interrupt" intervention for nurses has been shown to reduce interruptions during medication administration.
Another safety protocol is to conduct regular safety audits and root cause analyses to identify potential vulnerabilities and areas for improvement. Hospitals can systematically review processes and protocols to detect and rectify issues before they lead to errors. A designated team can analyze the data, assess compliance with protocols, and evaluate the effectiveness of safety measures to develop a plan of action to address any issues.
Additionally, hospitals should provide education and training to healthcare professionals on identifying and reporting medical errors, as well as implementing corrective interventions to create a culture of safety. This includes understanding the different types of medical errors, such as surgical, diagnostic, medication, and communication errors, and their contributing factors to develop effective prevention strategies.

Surgical errors are preventable and can cause adverse effects
Surgical errors are preventable, yet they continue to occur at a high rate, with 10% of preventable patient harm in healthcare attributed to operating theatres. Surgical errors can cause adverse effects and are a leading cause of death and injury. Preventable adverse events in hospitals are a significant issue, with studies showing that 58% of hospital admissions experiencing adverse events in New York and 53% in Colorado and Utah were attributable to errors. This equates to around 44,000–98,000 deaths per year in US hospitals due to medical errors.
Surgical errors are a type of medical error that includes wrong-site, wrong-patient, wrong-procedure, and foreign body retention errors. These errors are preventable, and protocols such as the Universal Protocol and surgical safety checklists have been developed to reduce their occurrence. Despite this, surgical errors still occur, and investigations have shown that common causes include clinician factors such as fatigue and distraction, as well as miscommunication, staffing issues, and organisational factors.
The consequences of surgical errors can be severe, with intraoperative errors being the primary issue in 75% of malpractice cases involving surgeons. To reduce these errors, healthcare professionals should be encouraged to report medical errors and identify contributing factors. Confidential reporting options are essential to this process, as they allow for the identification of system deficiencies and failures. By understanding the underlying causes of errors, healthcare institutions can develop corrective measures and preventative strategies to improve patient safety and reduce adverse events.
Root cause analysis (RCA) is one method used to identify the factors contributing to adverse events. RCA focuses on systems and processes rather than individual actions. For example, after a patient with an erythromycin allergy was prescribed azithromycin and suffered an anaphylactic reaction, an action plan to educate medical staff about drug interactions was developed, and an electronic medical record "stop alert" was implemented to prevent similar incidents.
Healthcare institutions should adopt a patient safety culture and implement corrective interventions to improve patient safety and reduce adverse events. By encouraging a culture of reporting and addressing medical errors, healthcare professionals can work together to develop effective protocols and improve patient outcomes.

Diagnostic errors are common and can be harmful
Medical errors are a leading cause of death and injury, and diagnostic errors are among the most common types of medical errors. According to doctor reviews, harmful diagnostic errors were found in at least 0.7% of adult hospital admissions, and most people will suffer a diagnostic error in their lifetime.
Diagnostic errors can have severe consequences, including death and harm to patients. Missed or delayed diagnoses, particularly of serious illnesses such as cancer, are a prominent reason for malpractice claims. In addition to the harm caused to patients, diagnostic errors can also result in increased financial costs for the healthcare system.
There are several factors that contribute to diagnostic errors. One factor is the use of heuristics, or "rules of thumb," by clinicians when making a diagnosis, especially when faced with common symptoms. While heuristics can be useful, they can also lead to errors if applied incorrectly. Poor teamwork and communication between clinicians have also been identified as predisposing factors for diagnostic errors, particularly in emergency medicine and surgery. Lack of reliable systems for common outpatient clinical situations, such as triaging acutely ill patients by telephone and following up on test results, can also increase the likelihood of diagnostic errors.
To reduce diagnostic errors, it is important to address the underlying factors that contribute to them. This includes improving healthcare professional education and training in the diagnostic process, as well as enhancing teamwork and communication between clinicians. Implementing health information technology, such as clinical decision support (CDS) systems, can also help improve diagnosis and reduce errors. Regular feedback to clinicians on their diagnostic performance is also essential, as it can help identify areas where improvements can be made.

System failures can lead to mistakes by healthcare workers
Medical errors are a leading cause of death and injury, with a significant number of people harmed as a result of medical errors in hospitals. System failures are a major contributor to these errors, and healthcare workers can find themselves in a cycle of distress and burnout as a result.
System failures can be attributed to poorly designed system structures and processes, as well as the complex and stressful nature of healthcare work. For example, cost-control measures that increase workload and the rate of medical errors, or keeping dangerous and routine medications together without pharmacist supervision. These failures can lead to healthcare workers making mistakes, such as medication errors, surgical errors, diagnostic errors, equipment failures, patient falls, hospital-acquired infections, and communication failures.
Healthcare workers involved in adverse events may experience emotional and psychological trauma, including stress, anxiety, depression, guilt, and shame. This can lead to disturbances, nightmares, and difficulty concentrating, as well as feelings of sadness and hopelessness. The impact of system failures on healthcare workers can also contribute to decreased morale and burnout, with physical and psychological manifestations such as exhaustion, insomnia, and decreased productivity.
To address system failures and improve patient safety, healthcare institutions should adopt a patient safety culture, implement corrective interventions, and encourage a shift to system-based thinking. This includes developing protocols for addressing medical errors, improving teamwork and communication, and establishing systems for patient safety incident reporting. By encouraging individuals involved in all aspects of healthcare to report medical errors, institutions can identify system deficiencies and failures and develop corrective measures to prevent future errors.
Additionally, peer support systems and workforce management strategies can help staff feel supported and reduce the impact of system failures on their well-being. Healthcare workers should also be empowered and rewarded for identifying medical errors to improve patient safety and break the cycle of error and distress.
