Key Terms to Review (32)
Adverse events: Adverse events are unintended and harmful outcomes that occur during medical care or treatment, which may or may not be related to the care provided. These events can range from minor complications to serious injuries or death, highlighting the importance of monitoring and improving quality in healthcare systems. Understanding adverse events is crucial for enhancing patient safety, reducing medical errors, and implementing effective quality measurement and improvement initiatives.
Barcoding Medication Administration: Barcoding medication administration is a safety process used in healthcare to ensure that the right patient receives the correct medication at the right dose and time. This system utilizes barcode technology to scan medication and patient identifiers, which significantly reduces the risk of medical errors related to drug administration and enhances patient safety by providing an additional layer of verification before medications are administered.
Clinical decision support tools: Clinical decision support tools are computer-based systems designed to assist healthcare providers in making clinical decisions by providing relevant patient information, evidence-based guidelines, and recommendations. These tools play a critical role in enhancing patient safety by reducing medical errors and supporting healthcare professionals in delivering effective care.
Communication errors: Communication errors refer to mistakes or misunderstandings that occur during the exchange of information between healthcare providers, patients, or their families. These errors can lead to misinterpretations of medical information, incorrect treatments, and ultimately compromise patient safety. Effective communication is vital in healthcare settings, as it ensures that all parties are on the same page regarding diagnoses, treatments, and care plans.
Computerized physician order entry systems: Computerized physician order entry (CPOE) systems are electronic platforms that allow healthcare providers to enter medical orders, such as medication prescriptions, laboratory tests, and imaging studies, directly into a computer system. These systems enhance patient safety by reducing the likelihood of errors associated with handwritten orders, improving communication among care teams, and providing clinical decision support to help avoid adverse drug interactions or other potential issues.
Continuous learning: Continuous learning is the ongoing, voluntary, and self-motivated pursuit of knowledge and skills for personal or professional development. This concept is especially important in healthcare, where the landscape is constantly evolving, and professionals must adapt to new technologies, treatments, and regulatory requirements to ensure patient safety and minimize medical errors.

This environment fosters a proactive approach to identifying potential risks and addressing medical errors before they lead to adverse outcomes, ultimately enhancing patient safety and care quality.
Diagnostic error: A diagnostic error occurs when a healthcare provider incorrectly identifies a patient's condition, which can lead to inappropriate or delayed treatment. This type of error can stem from misinterpretation of clinical findings, insufficient information, or cognitive biases that affect the decision-making process. The impact of diagnostic errors is significant as they can compromise patient safety and lead to adverse health outcomes, underscoring the importance of accuracy in medical diagnosis.
Electronic health record: An electronic health record (EHR) is a digital version of a patient’s paper chart that contains comprehensive medical history and treatment information. EHRs are designed to be shared across different healthcare settings, enabling better coordination of care, improved patient safety, and the reduction of medical errors. By providing real-time access to patient data, EHRs play a critical role in enhancing communication among healthcare providers and supporting clinical decision-making.
Evidence-based practice: Evidence-based practice is a problem-solving approach to healthcare that integrates the best available evidence from research, clinical expertise, and patient values to make informed decisions about patient care. This method enhances the quality of healthcare delivery by ensuring that treatments and interventions are backed by scientific data and real-world experiences, ultimately leading to improved patient outcomes.
Healthcare-associated infections: Healthcare-associated infections (HAIs) are infections that patients acquire while receiving treatment for medical or surgical conditions in a healthcare setting.

Medication error: A medication error is a preventable event that may cause or lead to inappropriate medication use or patient harm while the medication is in the control of healthcare professionals, patients, or consumers. This concept is closely linked to patient safety, as errors can occur at any stage of the medication process—from prescribing and dispensing to administration and monitoring—leading to adverse effects for patients. Understanding medication errors is crucial for developing strategies to improve healthcare systems and enhance the safety of medical practices.
Medication reconciliation: Medication reconciliation is a systematic process designed to ensure that a patient's medication lists are accurate and complete during transitions of care. This process helps to identify and resolve discrepancies in medications, which is crucial for preventing errors that could jeopardize patient safety. By accurately documenting a patient's medication history and comparing it to new prescriptions or changes, healthcare providers can reduce the risk of adverse drug events and improve overall patient outcomes.
Never Events: Never events are serious medical errors that are clearly identifiable, measurable, and preventable, which should never occur in a healthcare setting. These incidents highlight significant failures in patient safety and quality of care, as they are events that should be entirely avoidable with proper protocols in place. Recognizing and addressing never events is crucial for improving healthcare systems and protecting patient well-being.
Patient engagement: Patient engagement refers to the involvement of patients in their own healthcare decisions, fostering a partnership between patients and providers. This concept emphasizes the importance of patients being informed and active participants in their care, which can lead to improved health outcomes, enhanced patient safety, and overall satisfaction with the healthcare experience.
